Spreading pathogen maps

So while the world is in the grip of the novel COVID-19 coronavirus pandemic, I’ve been thinking about those fictional user interfaces that appear in pandemic movies that project how quickly the infectious-agent-in-question will spread. The COVID-19 pandemic is a very serious situation. Most smart people are sheltering in place to prevent an overwhelmed health care system and finding themselves with some newly idle cycles (or if you’re a parent like me, a lot fewer idle cycles). Looking at this topic through the lens of sci-fi is not to minimize what’s happening around us as trivial, but to process the craziness of it all through this channel that I’ve got on hand. I did it for fascism, I’ll do it for this. Maybe this can inform some smart speculative design.

Caveat #1: As a public service I have included some information about COVID-19 in the body of the post with a link to sources. These are called out the way this paragraph is, with a SARS-CoV-2 illustration floated on the left. I have done as much due diligence as one blogger can do to not spread disinformation, but keep in mind that our understanding of this disease and the context are changing rapidly. By the time you read this, facts may have changed. Follow links to sources to get the latest information. Do not rely solely on this post as a source. If you are reading this from the relative comfort of the future after COVID-19, feel free to skip these.

Get on a boat, Hongkongers, you can’t even run for the hills! Contagion (2011)

And yes, this is less of my normal fare of sci-fi and more bio-fi, but it’s still clearly a fictional user interface, so between that and the world going pear-shaped, it fits well enough. I’ll get back to Blade Runner soon enough. I hope.

Giving credit where it’s due: All but one of the examples in this post were found via the TV tropes page for Spreading Disaster Map Graphic page, under live-action film examples. I’m sure I’ve missed some. If you know of others, please mention it in the comments.

Four that are extradiegetic and illustrative

This first set of pandemic maps are extradiegetic.

Vocabulary sidebar: I use that term a lot on this blog, but if you’re new here or new to literary criticism, it bears explanation. Diegesis is used to mean “the world of the story,” as the world in which the story takes place is often distinct from our own. We distinguish things as diegetic and extradiegetic to describe when they occur within the world of the story, or outside of it, respectively. My favorite example is when we see a character in a movie walking down a hallway looking for a killer, and we hear screechy violins that raise the tension. When we hear those violins, we don’t imagine that there is someone in the house who happens to be practicing their creepy violin. We understand that this is extradiegetic music, something put there to give us a clue about how the scene is meant to feel.

So, like those violins, these first examples aren’t something that someone in the story is looking at. (Claude Paré? Who the eff is—Johnson! Get engineering! Why are random names popping up over my pandemic map?) They’re something the film is doing for us in the audience.

The Killer that Stalked New York (1950) is a short about a smallpox infection of New York City.
Edge of Tomorrow (2014) has this bit showing the Mimics, spreading their way across Europe.
The end of Rise of the Planet of the Apes (2011) shows the fictional virus ALZ-113 spreading.
The beginning of Dawn of the Planet of the Apes (2014) repeats the fictional virus ALZ-113 spreading, but augments it with video overlays.

There’s not much I feel the need to say about these kinds of maps, as they are a motion graphic and animation style. I note at least two use aposematic signals in their color palette and shapes, but that’s just because it helps reinforce for the audience that whatever is being shown here is a major threat to human life. But I have much more authoritative things to say about systems that are meant to be used.

Before we move on, here’s a bonus set of extradiegetic spreading-pathogen maps I saw while watching the Netflix docuseries Pandemic: How to Prevent an Outbreak, as background info for this post.

Five that are diegetic and informative

The five examples in this section are spread throughout the text for visual interest, but presented in chronological order. They are The Andromeda Strain (1977), Outbreak (1995), Evolution (2001), Contagion (2011), and World War Z (2013). I highly recommend Contagion for the acting, movie making, the modeling, and some of the facts it conveys. For instance, I think it’s the only film that discusses fomites. Everyone should know about fomites.

Since I raise their specter: As of publication of this post the CDC stated that fomites are not thought to be the main way the COVID-19 novel coronavirus spreads, but there are recent and conflicting studies. The scientific community is still trying to figure this out. The CDC says for certain it spreads primarily through sneezes, coughs, and being in close proximity to an infected person, whether or not they are showing symptoms.

Note that these five spreading pathogen examples are things that characters are seeing in the diegesis, that is, in the context of the story. These interfaces are meant to convey useful information to the characters as well as us in the audience.

Which is as damning a setup as I can imagine for this first example from The Andromeda Strain (1971). Because as much as I like this movie, WTF is this supposed to be? “601” is explained in the dialogue as the “overflow error” of this computer, but the pop-art seizure graphics? C’mon. There’s no way to apologize for this monstrosity.

This psychedelic nonsense somehow tells the bunkered scientists about how fast the eponymous Andromeda Strain will spread. (1971) Somehow the CRT gets nervous, too.

I’m sorry that you’ll never get those 24 seconds back. But at least we can now move on to look at the others, which we can break down into the simple case of persuasion, and the more complex case of use.

The simple case

In the simplest case, these graphics are shown to persuade an authority to act. That’s what happening in this clip from Outbreak (1995).

General Donald McClintock delivers a terrifying White House Chief-of-Staff Briefing about the Motaba virus. Outbreak (1995)

But if the goal is to persuade one course of action over another, some comparison should be made between two options, like, say, what happens if action is taken sooner rather than later. While that is handled in the dialogue of many of these films—and it may be more effective for in-person persuasion—I can’t help but think it would be reinforcing to have it as part of the image itself. Yet none of our examples do this.

Compare the “flatten the curve” graphics that have been going around. They provide a visual comparison between two options and make it very plain which is the right one to pick. One that stays in the mind of the observer even after they see it. This is one I’ve synthesized and tweaked from other sources.

This is a conceptual diagram, not a chart. The capacity bar is terrifyingly lower on actual charts. Stay home as much as you can. Special shouts out to Larry West.

There is a diegetic possibility, i.e., that no one amidst the panic of the epidemic has the time to thoughtfully do more than spit out the data and handle the rest with conversation. But we shouldn’t leave it at that, because there’s not much for us to learn there.

More complex case

The harder problem is when these displays are for people who need to understand the nature of the threat and determine the best course of action, and now we need to talk about epidemiology.

Caveat #2: I am not an epidemiologist. They are all really occupied for the foreseeable future, so I’m not even going to reach out and bother one of them to ask their opinions on this post. Like I said before about COVID-19, I really hope you don’t come to sci-fi interfaces to become an expert in epidemiology. And, since I’m just Some Guy on the Internet Who Has Read Some Stuff on the Internet, you should take whatever you learn here with a grain of salt. If I get something wrong, please let me know. Here are my major sources:

Kate Winslet, playing epidemiologist Dr. Erin Mears in Contagion (2011), is probably more qualified than me. Hey, Kate: Call me. I have questions.

Caveat #3: To discuss using technology in our species’ pursuit of an effective global immune system is to tread into some uncomfortable territory. ​Because of the way disease works, it is not enough to surveil the infected. We must always surveil the entire population, healthy or not, for signs of a pathogen outbreak, so responses can be as swift and certain as possible. We may need to surveil certain at-risk or risk-taking populations quite closely, as potential superspreaders. Otherwise we risk getting…well…*gestures vaguely at the USA*. I am pro-privacy, so know that when I speak about health surveillance in this post, I presume that we are simultaneously trying to protect as much “other” privacy as we can, maybe by tracking less-abusable, less-personally identifiable signals. I don’t pretend this is a trivial task, and I suspect the problem is more wicked than merely difficult to execute. But health surveillance must happen, and for this reason I will speak of it as a good thing in this context.

Making this seem a lot less stupid than it first appeared.

Caveats complete? We’ll see.

Epidemiology is a large field of study, so for purposes of this post, we’re talking about someone who studies disease at the level of the population, rather than individual cases. Fictional epidemiologists appear when there is an epidemic or pandemic in the plot, and so are concerned with two questions: What are we dealing with? and What do we need to do?

Part 1: What are we dealing with?

Our response should change for different types of threat. So it’s important for an epidemiologist to understand the nature of a pathogen. There are a few scenes in Contagion where we see scientists studying a screen with gene sequences and a protein-folding diagram, and this touches on understanding the nature of the virus. But this is a virologists view, and doesn’t touch on most of what an epidemiologist is ultimately hoping to build first, and that’s a case definition. It is unlikely to appear in a spreading pathogen map, but it should inform one. So even if your pathogen is fictional, you ought to understand what one is.

A screen grab from Contagion (2011), showing a display for a virologist, including gene sequences, and spectroscopy.
“We’ve sequenced the virus and determined its origin, and we’ve modeled the way it edges the cells of the lung and the brain…” —Dr. Hextall, Contagion (2011)

A case definition is the standard shared definition of what a pathogen is; how a real, live human case is classified as belonging to an epidemic or not. Some case definitions are built for non-emergency cases, like for influenza. The flu is practically a companion to humanity, i.e., with us all the time, and mutates, so its base definition for health surveillance can be a little vague. But for the epidemics and pandemics that are in sci-fi, they are building a case definition for outbreak investigations. These are for a pathogen in a particular time and place, and act as a standard for determining whether or not a given person is counted as a case for the purposes of studying the event.

Case definition for outbreak investigations

The CDC lists the following as the components of a case definition.

  • Clinical criteria
    • Clinical description
    • Confirmatory laboratory tests
      • These can be pages long, with descriptions of recommended specimen collections, transportation protocols, and reporting details.
    • Combinations of symptoms (subjective complaints)
    • Signs (objective physical findings)
    • Source
  • (Sometimes) Specifics of time and place.

There are sometimes different case definitions based on the combination of factors. COVID-19 case definitions with the World Health Organization, for instance, are broken down between suspect, probable, and confirmed. A person showing all the symptoms and who has been in an area where an infected person was would be suspect. A person whose laboratory results confirmed the presence of SARS-CoV-2 is confirmed. Notably for a map, these three levels might warrant three levels of color.

As an example, here is the CDC case definition for ebola, as of 09 JUL 2019.

https://www.cdc.gov/vhf/ebola/clinicians/evaluating-patients/case-definition.html

n.b. Case definitions are unlikely to work on screen

Though the case definition is critical to epidemiology, and may help the designer create the spreading pathogen map (see the note about three levels of color, above), but the thing itself is too text-heavy to be of much use for a sci-fi interface, which rely much more on visuals. Better might be the name or an identifying UUID to the definition. WHO case references look like this: WHO/COVID-19/laboratory/2020.5 I do not believe the CDC has any kind of UUID for its case definitions.

While case definitions don’t work on screen, counts and rates do. See below under Surveil Public Health for more on counts and rates.

Disease timeline

Infectious disease follows a fairly standard order of events, depicted in the graphic below. Understanding this typical timeline of events helps you understand four key metrics for a given pathogen: chains of transmission, R0, SI, and CFR.

A redesigned graphic from the CDC Principles epidemiology handbook, showing susceptibility, exposure, subclinical disease with pathologic changes and the beginning of an infectious period, the onset of symptoms and beginning of clinical disease, diagosis, the end of the infectious period, and a resolution of recovery, life-long disability, or death.

For each of the key metrics, I’ll list ranges and variabilities where appropriate. These are observed attributes in the real world, but an author creating a fictional pathogen, or a sci-fi interfaces maker needing to illustrate them, may need to know what those numbers look like and how they tend to behave over time so they can craft these attributes.

Chains of Transmission

What connects the individual cases in an epidemic are the methods of transmission. The CDC lists the following as the basics of transmission.

  • Reservoir: where the pathogen is collected. This could be the human body, or a colony of infected mynocks, a zombie, or a moldy Ameglian Major flank steak forgotten in a fridge. Or your lungs.
  • Portal of exit, or how the pathogen leaves the reservoir. Say, the open wound of a zombie, or an innocent recommendation, or an uncovered cough.
  • Mode of transmission tells how the pathogen gets from the portal of exit to the portal of entry. Real-world examples include mosquitos, fomites (you remember fomites from the beginning of this post, don’t you?), sex, or respiratory particles.
  • Portal of entry, how the pathogen infects a new host. Did you inhale that invisible cough droplet? Did you touch that light saber and then touch your gills? Now it’s in you like midichlorians.
  • Susceptible host is someone more likely than not to get the disease.

A map of this chain of transmission would be a fine secondary-screen to a spreading pathogen map, illustrating how the pathogen is transmitted. After all, this will inform the containment strategies.

Variability: Once the chain of transmission is known, it would only change if the pathogen mutated.

Basic Rate of Reproduction = How contagious it is

A famous number that’s associated with contagiousness is the basic reproduction rate. If you saw Contagion you’ll recall this is written as R0, and pronounced “R-naught.” It describes, on average, how many people an infected person will infect before they stop being infectious.

  • If R0 is below 1, an infected person is unlikely to infect another person, and the pathogen will quickly die out.
  • If R0 is 1, an infected person is likely to infect one other, and the disease will continue through a population at a steady rate without intervention.
  • If R0 is higher than 1, a pathogen stands to explode through a population.

The CDC book tells me that R0 describes how the pathogen would reproduce through the population with no intervention, but other sources talk of lowering the R0 so I’m not certain if those other sources are using it less formally, or if my understanding is wrong. For now I’ll go with the CDC, and talk about R0 as a thing that is fixed.

It, too, is not an easy thing to calculate. It can depend on the duration of contagiousness after a person becomes infected, or the likelihood of infection for each contact between a susceptible person and an infectious person or vector, and the contact rate.

Variability: It can change over time. When a novel pathogen first emerges, the data is too sparse and epidemiologists are scrambling to do the field work to confirm cases. As more data comes in and numbers get larger, the number will converge toward what will be its final number.

It can also differ based on geography, culture, geopolitical boundaries, and the season, but the literature (such as I’ve read) refers to R0 as a single number.

Range: The range of R0 >1 can be as high as 12–18, but measles morbillivirus is an infectious outlier. Average range of R0, not including measles, of this sample is 2.5–5.2. MEV-1 from Contagion has a major dramatic moment when it mutates and its predicted R0 becomes 4, making it roughly as contagious as the now-eradicated killer smallpox.

Data from https://en.wikipedia.org/wiki/Basic_reproduction_number

Serial Interval = How fast it spreads

Serial interval is the average time between successive cases in a chain of transmission. This tells the epidemiologist how fast a pathogen stands to spread through a population.

Variability: Like the other numbers, SI is calculated and updated with new cases while an epidemic is underway, but tend to converge toward a number. SI for some respiratory diseases is charted below. Influenza A moves very fast. Pertussis is much slower.

Range: As you can see in the chart, SI can be as fast as 2.2 days, or as slow as 22.8 days. The median in this set is 14 days and the average is 12.8. SARS-CoV-2 is currently estimated to be about 4 days, which is very fast.

Data from: https://academic.oup.com/aje/article/180/9/865/2739204

CFR = How deadly it is

The case fatality rate is a percentage that any given case will prove fatal. It is very often shortened to CFR. This is not always easy to calculate.

Variability: Early in a pandemic it might be quite low because hospital treatment is still available. Later in a pandemic, as hospital and emergency rooms are packed full, the CFR might raise quite high. Until a pathogen is eradicated, the precise CFR is changing with each new case. Updates can occur daily, or in real time with reports. In a sci-fi world, it could update real time directly from ubiquitous sensors, and perhaps predicted by a specialty A.I. or precognitive character.

Range: Case fatality rates range from the incurable, like kuru, at 100%. to 0.001% for chickenpox affecting unvaccinated children. The CFR changes greatly at the start of a pandemic and slowly converges towards its final number.

So, if the spreading pathogen map is meant to convey to an epidemiologist the nature of the pathogen, it should display these four factors:

  1. Mode of Transmission: How it spreads
  2. R0: How contagious it is
  3. SI: How fast it spreads
  4. CFR: How deadly it is

Part 2: What do we do?

An epidemiologist during an outbreak has a number of important responsibilities beyond understanding the nature of the pathogen. I’ve taken a crack at listing those below. Note: this list is my interpretation of the CDC materials, rather than their list. As always, offer corrections in comments.

  • Surveil the current state of things
  • Prevent further infections
  • Communicate recommendations

Epidemiology has other non-outbreak functions, but those routine, non-emergency responsibilities rarely make it to cinema. And since “communicate recommendations” is pretty covered under “The Simple Case,” above, the rest of this post will be dedicated to health surveillance and prevention tools.

Surveil the current state of things

In movies the current state of things is often communicated via the spreading pathogen map in some command and control center. The key information on these maps are counts and rates.

Counts and Rates

The case definition (above) helps field epidemiologists know which cases to consider in the data set for a given outbreak. They routinely submit reports of their cases to central authorities like the CDC or WHO, who aggregate them into counts, which are tallies of known cases. (And though official sources in the real world are rightly cautious to do it, sci-fi could also include an additional layer of suspected or projected cases.) Counts, especially over time, are important for tracking the spread of a virus. Most movie goers have basic numeracy, so red number going up = bad is an easy read for an audience.

Counts can be broken down into many variables. Geopolitical regions make sense as governmental policies and cultural beliefs can make meaningful distinctions in how a pathogen spreads. In sci-fi a speculative pathogen might warrant different breakdowns, like frequency of teleportation, or time spent in FTL warp fields, or genetic distance from the all-mother.

In the screen cap of the John Hopkins COVID-19 tracker, you can see counts high in the visual hierarchy for total confirmed (in red), total deaths (in white), and total recovered (in green). The map plots current status of the counts.

From the Johns Hopkins COVID-19 tracker, screen capped in the halcyon days of 23 MAR 2020.

Rates is another number that epidemiologists are interested in, to help normalize the spread of a pathogen for different group sizes. (Colloquially, rate often implies change over time, but in the field of epidemiology, it is a static per capita measurement of a point in time.) For example, 100 cases is around a 0.00001% rate in China, with its population of 1.386 billion, but it would be a full 10% rate of Vatican City, so count can be a poor comparison to understand how much of a given population is affected. By representing the rates alongside the counts you can detect if it’s affecting a subgroup of the global population more or less than others of its kind, which may warrant investigation into causes, or provide a grim lesson to those who take the threat lightly.

Counts and rates over time

The trend line in the bottom right of the Johns Hopkins dashboard helps understand how the counts of cases are going over time, and might be quite useful for helping telegraph the state of the pandemic to an audience, though having it tucked in a corner and in orange may not draw attention as it needs to for instant-understanding.

These two displays show different data, and one is more cinegenic than the other. Confirmed cases, on the left, is a total, and at best will only ever level off. If you know what you’re looking at, you know that older cases represented by the graph are…uh…resolved (i.e. recovery, disability, or death) and that a level-off is the thing we want to see there. But the chart on the right plots the daily increase, and will look something like a bell curve when the pandemic comes to an end. That is a more immediate read (bad thing was increasing, bad thing peaked, bad thing is on the decline) and so I think is better for cinema.

At a glance you can also tell that China appears to have its shit sorted. [Obviously this is an old screen grab.]

In the totals, sparklines would additionally help a viewer know whether things are getting better or getting worse in the individual geos, and would help sell the data via small multiples on a close-up.

Plotting cases on maps

Counts and rates are mostly tables of numbers with a few visualizations. The most cinegenic thing you can show are cases on geopolitical maps. All of the examples, except the trainwreck that is The Andromedia Strain pathogen map, show this, even the extradiegetic ones. Real-world pathogens mostly spread through physical means, so physical counts of areas help you understand where the confirmed cases are.

Which projection?

But as we all remember from that one West Wing scene, projections have consequences. When wondering where in the world do we send much-needed resources, Mercator will lie to you, exaggerating land at the poles at the expense of equatorial regions. I am a longtime advocate for alternate projections, such as—from the West Wing scene—the Gall-Peters. I am an even bigger big fan of Dymaxion and Watterman projections. I think they look quite sci-fi because they are familiar-but-unfamiliar, and they have some advantages for showing things like abstract routes across the globe.

A Dymaxion or Fuller projection of the earth.

If any supergenre is here to help model the way things ought to be, it’s sci-fi. If you only have a second or less of time to show the map, then you may be locked to Mercator for its instant-recognizability, but if the camera lingers, or you have dialogue to address the unfamiliarity, or if the art direction is looking for uncanny-ness, I’d try for one of the others.

What is represented?

Of course you’re going to want to represent the cases on the map. That’s the core of it. And it may be enough if the simple takeaway is thing bad getting worse. But if the purpose of the map is to answer the question “what do we do,” the cases may not be enough. Recall that another primary goal of epidemiologists is to prevent further infections. And the map can help indicate this and inform strategy.

Take for instance, 06 APR 2020 of the COVID-19 epidemic in the United States. If you had just looked at a static map of cases, blue states had higher counts than red states. But blue states had been much more aggressive in adopting “flattening the curve” tactics, while red states had been listening to Trump and right wing media that had downplayed the risk for many weeks in many ways. (Read the Nate Silver post for more on this.) If you were an epidemiologist, seeing just the cases on that date might have led you to want to focus social persuasion resources on blue states. But those states have taken the science to heart. Red states on the other hand, needed a heavy blitz of media to convince them that it was necessary to adopt social distancing and shelter-in-place directives. With a map showing both cases and social acceptance of the pandemic, it might have helped an epidemiologist make the right resource allocation decision quickly.

Another example is travel routes. International travel played a huge role in spreading COVID-19, and visualizations of transportation routes can prove more informative in understanding its spread than geographic maps. Below is a screenshot of the New York Times’ beautiful COVID-19 MAR 2020 visualization How the Virus Got Out, which illustrates this point.

Other things that might be visualized depend, again, on the chain of transmission.

  • Is the pathogen airborne? Then you might need to show upcoming wind and weather forecasts.
  • Is the reservoir mosquitoes? Then you might want to show distance to bodies of still water.
  • Is the pathogen spread through the mycelial network? Then you might need to show an overlay of the cosmic mushroom threads.

Whatever your pathogen, use the map to show the epidemiologist ways to think about its future spread, and decide what to do. Give access to multiple views if needed.

How do you represent it?

When showing intensity-by-area, there are lots of ways you could show it. All of them have trade offs. The Johns-Hopkins dashboard uses a Proportional Symbol map, with a red dot, centered on the country or state, the radius of which is larger for more confirmed cases. I don’t like this for pandemics, mostly because the red dots begin to overlap and make it difficult to any detail without interacting with the map to get a better focus. It does make for an immediate read. In this 23 MAR 2020 screen cap, it’s pretty obvious that the US, Europe, and China are current hotspots, but to get more detail you have to zoom in, and the audience, if not the characters, don’t have that option. I suppose it also provides a tone-painting sense of unease when the symbols become larger than the area they are meant to represent. It looks and feels like the area is overwhelmed with the pathogen, which is an appropriate, if emotional and uninformative, read.

The Johns-Hopkins dashboard uses a proportional symbol map. And I am distraught at how quaint those numbers seem now, much less what they will be in the future.

Most of the sci-fi maps we see are a variety of Chorochromatic map, where color is applied to the discrete thing where it appears on the map. (This is as opposed to a Cloropleth map, where color fills in existing geopolitical regions.) The chorochromatic option is nice for sci-fi because the color makes a shape—a thing—that does not know of or respect geopolitical boundaries. See the example from Evolution below.

Governor Lewis watches the predicted spread of the Glen Canyon asteroid organisms out of Arizona and to the whole of North America. Evolution (2001)

It can be hard to know (or pointlessly-detailed) to show exactly where a given thing is on a map, like, say, where infected people literally are. To overcome this you could use a dot-distribution map, as in the Outbreak example (repeated below so you don’t have to scroll that far back up).

Outbreak (1995), again.

Like many such maps, the dot-distribution becomes solid red to emphasize passing over some magnitude threshold. For my money, the dots are a little deceptive, as if each dot represented a person rather than part of a pattern than indicates magnitude, but a glance at the whole map gives the right impression.

For a real world example of dot-distribution for COVID-19, see this example posted to reddit.com by user Edward-EFHIII.

COVID-19 spread from January 23 through March 14th.

Often times dot-distribution is reserved for low magnitudes, and once infections are over a threshold, become cloropleth maps. See this example from the world of gaming.

A screen grab of the game Plague, Inc., about 1/3 of the way through a game.
In Plague, Inc., you play the virus, hoping to win against humanity.

Here you can see that India and Australia have dots, while China, Kyrgyzstan, Tajikistan, Turkmenistan, and Afghanistan (I think) are “solid” red.

The other representation that might make sense is a cartogram, in which predefined areas (like country or state boundaries) are scaled to show the magnitude of a variable. Continuous-area cartograms can look hallucinogenic, and would need some explanation by dialogue, but can overcome the inherent bias that size = importance. It might be a nice secondary screen alongside a more traditional one.

On the left, a Choropleth map of the 2012 US presidential election, where it looks like red states should have won. On the right, a continuous cartogram with state sizes scaled to reflect states’ populations, making more intuitive sense why blue states carried the day.

Another gorgeous projection dispenses with the geographic layout. Dirk Brockman, professor at the Institute for Theoretical Biology, Humboldt University, Berlin, developed a visualization that places the epicenter of a disease at the center of a node graph, and plots every city around it based on how many airport flights it takes to get there. Plotting proportional symbols to this graph makes the spread of the disease radiate in mostly- predictable waves. Pause the animation below and look at the red circles. You can easily predict where the next ones will likely be. That’s an incredibly useful display for the epidemiologist. And as a bonus, it’s gorgeous and a bit mysterious, so would make a fine addition in a sci-fi display to a more traditional map. Read more about this innovative display on the CityLab blog. (And thanks, Mark Coleran, for the pointer.)

How does it move?

First I should say I don’t know that it needs to move. We have information graphics that display predicted change-over-area without motion: Hurricane forecast maps. These describe a thing’s location in time, and simultaneously, the places it is likely to be in the next few days.

If you are showing a chorochromatic map, then you can use “contour lines” or color regions to demonstrate the future predictions.

Not based on any real pathogen.

Another possibility is small multiples, where the data is spread out over space instead of time. This makes it harder to compare stages, but doesn’t have the user searching for the view they want. You can mitigate this with small lines on each view representing the boundaries of other stages.

Not based on any real pathogen.

The side views could also represent scenarios. Instead of +1, +2, etc., the side views could show the modeled results for different choices. Perhaps those scenario side views and their projected counts could be animated.

To sing the praises of the static map: Such a view, updated as data comes in, means a user does not have to wait for the right frame to pop up, or interact with a control to get the right piece of information, or miss some detail when they just happened to have the display paused on the wrong frame of an animation.

But, I realize that static maps are not as cinegenic as a moving map. Movement is critical to cinema, so a static map, updating only occasionally as new data comes in, could look pretty lifeless. Animation gives the audience more to feel as some red shape slowly spreads to encompass the whole world. So, sure. I think there are better things to animate than the primary map, but doing so puts us back into questions of style rather than usability, so I’ll leave off that chain of thought and instead show you the fourth example in this section, Contagion.

Prevent further transmissions: Containment strategies

The main tactic for epidemiological intervention is to deny pathogens the opportunity to jump to new hosts. The top-down way to do this is to persuade community leaders to issue broad instructions, like the ones around the world that have us keeping our distance from strangers, wearing masks and gloves, and sheltering-in-place. The bottom-up tactic is to identify those who have been infected or put at risk for contracting a pathogen from an infected person. This is done with contact tracing.

Contain Known Cases

When susceptible hosts simply do not know whether or not they are infected, some people will take their lack of symptoms to mean they are not infectious and do risky things. If these people are infectious but not yet showing symptoms, they spread the disease. For this reason, it’s critical to do contact tracing of known cases to inform and encourage people to get tested and adopt containment behaviors.

Contact tracing

There are lots of scenes in pathogen movies where scientists stand around whiteboards with hastily-written diagrams of who-came-into-contact-with-whom, as they hope to find and isolate cases, or to find “patient 0,” or to identify super-spreaders and isolate them.

An infographic from Wikimedia showing a flow chart of contact tracing. Its label reads “Contact tracing finds cases quickly so they can be isolated and reduce spread.”

These scenes seem ripe for improvement by technology and AI. There are opt-in self-reporting systems, like those that were used to contain COVID-19 in South Korea, or the proposed NextTrace system in the West. In sci-fi, this can go further.

Scenario: Imagine an epidemiologist talking to the WHO AI and asking it to review public footage, social media platforms, and cell phone records to identify all the people that a given case has been in contact with. It could even reach out and do field work, calling humans (think Google Duplex) who might be able to fill in its information gaps. Field epidemiologists are focused on situations when the suspected cases don’t have phones or computers.

Or, for that matter, we should ask why the machine should wait to be asked. It should be set up as an agent, reviewing these data feeds continually, and reaching out in real time to manage an outbreak.

  • SCENE: Karen is walking down the sidewalk when her phone rings.
  • Computer voice:
  • Good afternoon, Karen. This is Florence, the AI working on behalf of the World Health Organization.
  • Karen:
  • Oh no. Am I sick?
  • Computer voice:
  • Public records indicate you were on a bus near a person who was just confirmed to be infected. Your phone tells me your heart rate has been elevated today. Can you hold the phone up to your face so I can check for a fever?
  • Karen does. As the phone does its scan, people on the sidewalk behind her can be seen to read texts on their phone and move to the other side of the street. Karen sees that Florence is done, and puts the phone back to her ear.
  • Computer voice:
  • It looks as if you do have a fever. You should begin social distancing immediately, and improvise a mask. But we still need a formal test to be sure. Can you make it to the testing center on your own, or may I summon an ambulance? It is a ten minute walk away.
  • Karen:
  • I think I can make it, but I’ll need directions.
  • Computer voice:
  • Of course. I have also contacted your employer and spun up an AI which will be at work in your stead while you self-isolate. Thank you for taking care of yourself, Karen. We can beat this together.

Design challenge: In the case of an agentive contact tracer, the display would be a social graph displayed over time, showing confirmed cases as they connect to suspected cases (using evidence-of-proximity or evidence-of-transmission) as well as the ongoing agent’s work in contacting them and arranging testing. It would show isolation monitoring and predicted risks to break isolation. It would prioritize cases that are greatest risk for spreading the pathogen, and reach out for human intervention when its contact attempts failed or met resistance. It could be simultaneously tracing contacts “forward” to minimize new infections and tracing contacts backward to find a pathogen’s origins.

Another consideration for such a display is extension beyond the human network. Most pathogens mutate and much more freely in livestock and wild animal populations, making their way into humans occasionally. it happened this way for SARS (bats → civets → people), MERS (bats → camels → people), and COVID-19 (bats → pangolin → people). (Read more about bats as a reservoir.) It’s not always bats, by the way, livestock are also notorious breeding grounds for novel pathogens. Remember Bird flu? Swine flu? This “zoonotic network” should be a part of any pathogen forensic or surveillance interface.

As far as SARS-CoV-2 is concerned, this is a passageway.

Design idea: Even the notion of what it means to do contact tracing can be rethought in sci-fi. Have you seen the Mythbusters episode “Contamination”? In it Adam Savage has a tube latexed to his face, right near his nose that drips a florescent dye at the same rate a person’s runny nose might drip. Then he attends a staged dinner party where, despite keeping a napkin on hand to dab at the fluid, the dye gets everywhere except the one germophobe. It brilliantly illustrates the notion of fomites and how quickly an individual can spread a pathogen socially.

Now imagine this same sort of tracing, but instead of dye, it is done with computation. A camera watches, say, grocery shelves, and notes who touched what where and records the digital “touch,” or touchprint, along with an ID for the individual and the area of contact. This touchprint could be exposed directly with augmented reality, appearing much like the dye under black light. The digital touch mark would only be removed from the digital record of the object if it is disinfected, or after the standard duration of surface stability expires. (Surface stability is how long a pathogen remains a threat on a given surface). The computer could further watch the object for who touches it next, and build an extended graph of the potential contact-through-fomites.

Ew, I got touchprint on me.

You could show the AR touchprint to the individual doing the touching, this would help remind them to wear protective gloves if the science calls for it, or to ask them to disinfect the object themselves. A digital touchprint could also be used for workers tasked with disinfecting the surfaces, or by disinfecting drones. Lastly, if an individual is confirmed to have the pathogen, the touchprint graph could immediately identify those who had touched an object at the same spot as the infected person. The system could provide field epidemiologists with an instant list of people to contact (and things to clean), or, if the Florence AI described above was active, the system could reach out to individuals directly. The amount of data in such a system would be massive, and the aforementioned privacy issues would be similarly massive, but in sci-fi you can bypass the technical constraints, and the privacy issues might just be a part of the diegesis.

In case you’re wondering how long that touch mark would last for SARS-CoV-2 (the virus that causes COVID-19), this study from the New England Journal of Medicine says it’s 4 hours for copper, 24 hours for paper and cardboard, and 72 hours on plastic and steel.

Anyway, all of this is to say that the ongoing efforts by the agent to do the easy contact tracing would be an excellent, complicated, cinegenic side-display to a spreading pathogen map.

Destroying non-human reservoirs

Another way to reduce the risk of infection is to seal or destroy reservoirs. Communities encourage residents to search their properties and remove any standing water to remove the breeding grounds for mosquitos, for example. There is the dark possibility that a pathogen is so lethal that a government might want to “nuke it from orbit” and kill even human reservoirs. Outbreak features an extended scene where soldiers seek to secure a neighborhood known to be infected with the fictional Motoba virus, and soldiers threaten to murder a man trying to escape with his family. For this dark reason, in addition to distance-from-reservoir, the location of actual reservoirs may be important to your spreading pathogen map. Maybe also counts of the Hail Mary tools that are available, their readiness, effects, etc.

To close out the topic of What Do We Do? Let me now point you to the excellent and widely-citied Medium article by Tomas Peuyo, “Act Today or People Will Die,” for thoughts on that real-world question.

The…winner(?)

At the time of publication, this is the longest post I’ve written on this blog. Partly that’s because I wanted to post it as a single thing, but also because it’s a deep subject that’s very important to the world, and there are lots and lots of variables to consider when designing one.

Which makes it not surprising that most of the examples in this mini survey are kind of weak, with only one true standout. That standout is the World War Z spreading disaster map, shown below.

World War Z (2013)

It goes by pretty quickly, but you can see more features discussed above in this clip than any of the other exmaples.

Description in the caption.
A combination of chorochromatic marking for the zombie infection, and cloropleth marking for countries. Note the signals showing countries where data is unavailable.
Description in the caption.
Along the bottom, rates (not cases) are expressed as “Population remaining.” That bar of people along the bottom would start slow and then just explode to red, but it’s a nice “things getting worse” moment. Maybe it’s a log scale?
Description in the caption.
A nice augmentation of the main graphic is down the right-hand side. A day count in the upper right (with its shout-out to zombie classic 28 Days Later), and what I’m guessing are resources, including nukes.

It doesn’t have that critical layer of forecasting data, but it got so much more right than its peers, I’m still happy to have it. Thanks to Mark Coleran for pointing me to it.

Let’s not forget that we are talking about fiction, and few people in the audience will be epidemiologists, standing up in the middle of the cinema (remember when we could go to cinemas?) to shout, “What’s with this R0 of 0.5? What is this, the LaCroix of viruses?” But c’mon, surely we can make something other than Andromeda Strain’s Pathogen Kaleidoscope, or Contagion’s Powerpoint wipe. Modern sci-fi interfaces are about spectacle, about overwhelming the users with information they can’t possibly process, and which they feel certain our heroes can—but they can still be grounded in reality.

Lastly, while I’ve enjoyed the escapism of talking about pandemics in fiction, COVID-19 is very much with us and very much a threat. Please take it seriously and adopt every containment behavior you can. Thank you for taking care of yourself. We can beat this together.

Routing Board

by

10

When the two AIs Colossus and Guardian are disconnected from communicating with each other, they try and ignore the spirit of the human intervention and reconnect on their own. We see the humans monitoring Colossus’ progress in this task on big board in the U.S. situation room. It shows a translucent projection map of the globe with white dots representing data centers and red icons representing missiles. Beneath it, glowing arced lines illustrate the connection routes Colossus is currently testing. When it finds that a current segment is ineffective, that line goes dark, and another segment extending from the same node illuminates.

For a smaller file size, the animated gif has been stilled between state changes, but the timing is as close as possible to what is seen in the film.

Forbin explains to the President, “It’s trying to find an alternate route.”

A first in sci-fi: Routing display 🏆

First, props to Colossus: The Forbin Project for being the first show in the survey to display something like a routing board, that is, a network of nodes through which connections are visible, variable, and important to stakeholders.

Paul Baran and Donald Davies had published their notion of a network that could, in real-time, route information dynamically around partial destruction of the network in the early 1960s, and this packet switching had been established as part of ARPAnet in the late 1960s, so Colossus was visualizing cutting edge tech of the time.

This may even be the first depiction of a routing display in all of screen sci-fi or even cinema, though I don’t have a historical perspective on other genres, like the spy genre, which is another place you might expect to see something like this. As always, if you know of an earlier one, let me know so I can keep this record up to date and honest.

A nice bit: curvy lines

Should the lines be straight or curvy? From Colossus’ point of view, the network is a simple graph. Straight lines between its nodes would suffice. But from the humans’ point of view, the literal shape of the transmission lines are important, in case they need to scramble teams to a location to manually cut the lines. Presuming these arcs mean that (and not just the way neon in a prop could bend), then the arcs are the right display. So this is good.

But, it breaks some world logic

The board presents some challenges with the logic of what’s happening in the story. If Colossus exists as a node in a network, and its managers want to cut it off from communication along that network, where is the most efficient place to “cut” communications? It is not at many points along the network. It is at the source.

Imagine painting one knot in a fishing net red and another one green. If you were trying to ensure that none of the strings that touch the red knot could trace a line to the green one, do you trim a bunch of strings in the middle, or do you cut the few that connect directly to the knot? Presuming that it’s as easy to cut any one segment as any other, the fewer number of cuts, the better. In this case that means more secure.

The network in Colossus looks to be about 40 nodes, so it’s less complicated than the fishing net. Still, it raises the question, what did the computer scientists in Colossus do to sever communications? Three lines disappear after they cut communications, but even if they disabled those lines, the rest of the network still exists. The display just makes no sense.

Before, happy / After, I will cut a Prez

Per the logic above, they would cut it off at its source. But the board shows it reaching out across the globe. You might think maybe they just cut Guardian off, leaving Colossus to flail around the network, but that’s not explicitly said in the communications between the Americans and the Russians, and the U.S. President is genuinely concerned about the AIs at this point, not trying to pull one over on the “pinkos.” So there’s not a satisfying answer.

It’s true that at this point in the story, the humans are still letting Colossus do its primary job, so it may be looking at every alternate communication network to which it has access: telephony, radio, television, and telegraph. It would be ringing every “phone” it thought Guardian might pick up, and leaving messages behind for possible asynchronous communications. I wish a script doctor had added in a line or three to clarify this.

  • FORBIN
  • We’ve cut off its direct lines to Guardian. Now it’s trying to find an indirect line. We’re confident there isn’t one, but the trouble will come when Colossus realizes it, too.

Too slow

Another thing that seems troubling is the slow speed of the shifting route. The segments stay illuminated for nearly a full second at a time. Even with 1960s copper undersea cables and switches, electronic signals should not take that long. Telephony around the world was switched from manual to automatic switching by the 1930s, so it’s not like it’s waiting on a human operating a switchboard.

You’re too slow!

Even if it was just scribbling its phone number on each network node and the words “CALL ME” in computerese, it should go much faster than this. Cinematically, you can’t go too fast or the sense of anticipation and wonder is lost, but it would be better to have it zooming through a much more complicated network to buy time. It should feel just a little too fast to focus on—frenetic, even.

This screen gets 15 seconds of screen time, and if you showed one new node per frame, that’s only 360 states you need to account for, a paltry sum compared to the number of possible paths it could test across a 38 node graph between two points.

Plus the speed would help underscore the frightening intelligence and capabilities of the thing. And yes I understand that that is a lot easier said than done nowadays with digital tools than with this analog prop.

Realistic-looking search strategies

Again, I know this was a neon, analog prop, but let’s just note that it’s not testing the network in anything that looks like a computery way. It even retraces some routes. A brute force algorithm would just test every possibility sequentially. In larger networks there are pathfinding algorithms that are optimized in different ways to find routes faster, but they don’t look like this. They look more like what you see in the video below. (Hat tip to YouTuber gray utopia.)

This would need a lot of art direction and the aforementioned speed, but it would be more believable than what we see.

What’s the right projection?

Is this the right projection to use? Of course the most accurate representation of the earth is a globe, but it has many challenges in presenting a phenomenon that could happen anywhere in the world. Not the least of these is that it occludes about half of itself, a problem that is not well-solved by making it transparent. So, a projection it must be. There are many, many ways to transform a spherical surface into a 2D image, so the question becomes which projection and why.

The map uses what looks like a hand-drawn version of Peirce quincuncial projection. (But n.b. none of the projection types I compared against it matched exactly, which is why I say it was hand-drawn.) Also those longitude and latitude lines don’t make any sense; though again, a prop. I like that it’s a non standard projection because screw Mercator, but still, why Peirce? Why at this angle?

Also, why place time zone clocks across the top as if they corresponded to the map in some meaningful way? Move those clocks.

I have no idea why the Peirce map would be the right choice here, when its principle virtue is that it can be tessellated. That’s kind of interesting if you’re scrolling and can’t dynamically re-project the coastlines. But I am pretty sure the Colossus map does not scroll. And if the map is meant to act as a quick visual reference, having it dynamic means time is wasted when users look to the map and have to orient themselves.

If this map was only for tracking issues relating to Colossus, it should be an azimuthal map, but not over the north pole. The center should be the Colossus complex in Colorado. That might be right for a monitoring map in the Colossus Programming Office. This map is over the north pole, which certainly highlights the fact that the core concern of this system is the Cold War tensions between Moscow and D.C. But when you consider that, it points out another failing. 

Later in the film the map tracks missiles (not with projected paths, sadly, but with Mattel Classic Football style yellow rectangles). But missiles could conceivably come from places not on this map. What is this office to do with a ballistic-missile submarine off of the Baja peninsula, for example? Just wait until it makes its way on screen? That’s a failure. Which takes us to the crop.

Crop

The map isn’t just about missiles. Colossus can look anywhere on the planet to test network connections. (Even nowadays, near-earth orbit and outer space.) Unless the entire network was contained just within the area described on the map, it’s excluding potentially vital information. If Colossus routed itself through through Mexico, South Africa, and Uzbekistan before finally reconnecting to Guardian, users would be flat out of luck using that map to determine the leak route. And I’m pretty sure they had a functioning telephone network in Mexico, South Africa, and the Balkan countries in the 1960s.

This needs a complete picture

SInce the missiles and networks with which Colossus is concerned are potentially global, this should be a global map. Here I will offer my usual fanboy shout-outs to the Dymaxion and Pacific-focused Waterman projection for showing connectedness and physical flow, but there would be no shame in showing the complete Peirce quincuncial. Just show the whole thing.

Maybe fill in some of the Pacific “wasted space” with a globe depiction turned to points of interest, or some other fuigetry. Which gives us a new comp something like this.

I created this proof of concept manually. With more time, I would comp it up in Processing or Python and it would be even more convincing. (And might have reached London.)

All told, this display was probably eye-opening for its original audience. Golly jeepers! This thing can draw upon resources around the globe! It has intent, and a method! And they must have cool technological maps in D.C.! But from our modern-day vantage point, it has a lot to learn. If they ever remake the film, this would be a juicy thing to fully redesign.

Cyberspace: the hardware

by

3

And finally we come to the often-promised cyberspace search sequence, my favourite interface in the film. It starts at 36:30 and continues, with brief interruptions to the outside world, to 41:00. I’ll admit there are good reasons not to watch the entire film, but if you are interested in interface design, this will be five minutes well spent. Included here are the relevant clips, lightly edited to focus on the user interfaces.

First, what hardware is required?

Johnny and Jane have broken into a neighbourhood computer shop, which in 2021 will have virtual reality gear just as today even the smallest retailer has computer mice. Johnny clears miscellaneous parts off a table and then sits down, donning a headset and datagloves.

jm-30-hardware-a

Headset

Headsets haven’t really changed much since 1995 when this film was made. Barring some breakthrough in neural interfaces, they remain the best way to block off the real world and immerse a user into the virtual world of the computer. It’s mildly confusing to a current day audience to hear Johnny ask for “eyephones”, which in 1995 was the name of a particular VR headset rather than the popular “iPhone” of today.

Video Phone Calls

by

2

The characters in Johnny Mnemonic make quite a few video phone calls throughout the film, enough to be grouped in their own section on interfaces.

The first thing a modern viewer will note is that only one of the phones resembles a current day handheld mobile. This looks very strange today and it’s hard to imagine why we would ever give up our beloved iPhones and Androids. I’ll just observe that accurately predicting the future is difficult (and not really the point) and move on.

More interesting is the variety of phones used. In films from the 1950s to the 1990s, everyone uses a desk phone with a handset. (For younger readers: that is the piece you picked up and held next to your ear and mouth. There’s probably one in your parents’ house.) The only changes were the gradual replacement of rotary dials by keypads, and some cordless handsets. In 21st century films everyone uses a small sleek handheld box. But in Johnny Mnemonic every phone call uses a different interface.

New Darwin

First is the phone call Johnny makes from the New Darwin hotel.

jm-3-phone-hotel-c-adjusted

As previously discussed, Johnny is lying in bed using a remote control to select numbers on the onscreen keypad. He is facing a large wall mounted TV/display screen, with what looks like a camera at the top. The camera is realistic but unusual: as Chapter 10 of Make It So notes, films very rarely show the cameras used in visual communication. Continue reading →

Galactica’s Wayfinding

by

image05

The Battlestar Galactica is a twisting and interlocking series of large hallways that provide walking access to all parts of the ship.  The hallways are poorly labeled, and are almost impossible for someone without experience to navigate. Seriously, look at these images and see if you can tell where you are, or where you’re supposed to head to find…well, anything.

image03

Billy (a young political assistant steeped in modern technology) finds this out after losing the rest of his tour group.

The hallways lack even the most basic signage that we expect in our commercial towers and office buildings.  We see no indication of what deck a given corridor is on, what bulkhead a certain intersection is located at, or any obvious markings on doorways.

We do see small, cryptic alphanumerics near door handles:

image02

Based off of current day examples, the alphanumeric would mark the bulkhead the door was at, the level it was on, and which section it was in.  This would let anyone who knew the system figure out where they were on the ship. Continue reading →

Internet 2021

by

1

The opening shot of Johnny Mnemonic is a brightly coloured 3D graphical environment. It looks like an abstract cityscape, with buildings arranged in rectangular grid and various 3D icons or avatars flying around. Text identifies this as the Internet of 2021, now cyberspace.

Internet 2021 display

Strictly speaking this shot is not an interface. It is a visualization from the point of view of a calendar wake up reminder, which flies through cyberspace, then down a cable, to appear on a wall mounted screen in Johnny’s hotel suite. However, we will see later on that this is exactly the same graphical representation used by humans. As the very first scene of the film, it is important in establishing what the Internet looks like in this future world. It’s therefore worth discussing the “look” employed here, even though there isn’t any interaction.

Cyberspace is usually equated with 3D graphics and virtual reality in particular. Yet when you look into what is necessary to implement cyberspace, the graphics really aren’t that important.

MUDs and MOOs: ASCII Cyberspace

People have been building cyberspaces since the 1980s in the form of MUDs and MOOs. At first sight these look like old style games such as Adventure or Zork. To explore a MUD/MOO, you log on remotely using a terminal program. Every command and response is pure text, so typing “go north” might result in “You are in a church.” The difference between MUD/MOOs and Zork is that these are dynamic multiuser virtual worlds, not solitary-player games. Other people share the world with you and move through it, adventuring, building, or just chatting. Everyone has an avatar and every place has an appearance, but expressed in text as if you were reading a book.

guest>>@go #1914
Castle entrance
A cold and dark gatehouse, with moss-covered crumbling walls. A passage gives entry to the forbidding depths of Castle Aargh. You hear a strange bubbling sound and an occasional chuckle.

Obvious exits:
path to Castle Aargh (#1871)
enter to Bridge (#1916)

Most impressive of all, these are virtual worlds with built-in editing capabilities. All the “graphics” are plain text, and all the interactions, rules, and behaviours are programmed in a scripting language. The command line interface allows the equivalent of Emacs or VI to run, so the world and everything in it can be modified in real time by the participants. You don’t even have to restart the program. Here a character creates a new location within a MOO, to the “south” of the existing Town Square:

laranzu>>@dig MyNewHome
laranzu>> @describe here as “A large and spacious cave full of computers”
laranzu>> @dig north to Town Square

The simplicity of the text interfaces leads people to think these are simple systems. They’re not. These cyberspaces have many of the legal complexities found in the real world. Can individuals be excluded from particular places? What can be done about abusive speech? How offensive can your public appearance be? Who is allowed to create new buildings, or modify existing ones? Is attacking an avatar a crime? Many 3D virtual reality system builders never progress that far, stopping when the graphics look good and the program rarely crashes. If you’re interested in cyberspace interface design, a long running textual cyberspace such as LambdaMOO or DragonMUD holds a wealth of experience about how to deal with all these messy human issues.

So why all the graphics?

So it turns out MUDs and MOOs are a rich, sprawling, complex cyberspace in text. Why then, in 1995, did we expect cyberspace to require 3D graphics anyway?

The 1980s saw two dimensional graphical user interfaces become well known with the Macintosh, and by the 1990s they were everywhere. The 1990s also saw high end 3D graphics systems becoming more common, the most prominent being from Silicon Graphics. It was clear that as prices came down personal computers would soon have similar capabilities.

At the time of Johnny Mnemonic, the world wide web had brought the Internet into everyday life. If web browsers with 2D GUIs were superior to the command line interfaces of telnet, FTP, and Gopher, surely a 3D cyberspace would be even better? Predictions of a 3D Internet were common in books such as Virtual Reality by Howard Rheingold and magazines such as Wired at the time. VRML, the Virtual Reality Markup/Modeling Language, was created in 1995 with the expectation that it would become the foundation for cyberspace, just as HTML had been the foundation of the world wide web.

Twenty years later, we know this didn’t happen. The solution to the unthinkable complexity of cyberspace was a return to the command line interface in the form of a Google search box.

Abstract or symbolic interfaces such as text command lines may look more intimidating or complicated than graphical systems. But if the graphical interface isn’t powerful enough to meet their needs, users will take the time to learn how the more complicated system works. And we’ll see later on that the cyberspace of Johnny Mnemonic is not purely graphical and does allow symbolic interaction.

Security Alert

The security alert occurs in two parts. The first is a paddock alert that starts on a single terminal but gets copied to the big shared screen. The second is a security monitor for the visitor center in which the control room sits.  Both of these live as part of the larger Jurassic Park.exe, alongside the Explorer Status panel, and take the place of the tour map on the screen automatically.

After Nedry disables security, the central system fires an alert as each of the perimeter fence systems go down.  Each section of the fence blinks red, with a large “UNARMED” on top of the section.  After blinking, the fence line disappears.

Iron Man HUD: Just the functions

In the last post we went over the Iron HUD components. There is a great deal to say about the interactions and interface, but let’s just take a moment to recount everything that the HUD does over the Iron Man movies and The Avengers. Keep in mind that just as there are many iterations of the suit, there can be many iterations of the HUD, but since it’s largely display software controlled by JARVIS, the functions can very easily move between exosuits.

Gauges

Along the bottom of the HUD are some small gauges, which, though they change iconography across the properties, are consistently present.

For the most part they persist as tiny icons and thereby hard to read, but when the suit reboots in a high-altitude freefall, we get to see giant versions of them, and can read that they are:

Ford Explorer Status

image00

One computer in the control room is dedicated to showing the status of the Jeeps out on tour, and where they currently are on the island.

Next to the vehicle outline, we see the words “Vehicle Type: Ford Explorer” (thank you, product placement) along with “EXP” 4–7.  EXP 4 & 5 look unselected, but have green dots next to them, while EXP 6 & 7 look selected with red dots next to them.  No characters interact with this screen. Mr. Arnold does tap on it with a pen (to make a point though, not to interact with it).

On the right hand side of the screen also see a top-down view of the car with the electric track shown underneath, and little red arrows pointing forward.  Below the graphic are the words “13 mph”.  The most visible and obvious indicator on the screen is the headlights.  A large “Headlights On” indicator is at the top of the screen, with highlighted cones coming out of the Jeep where the headlights are on the car.

Weather Monitor

Jurassic Park’s weather prediction software sits on a dedicated computer. It pulls updates from some large government weather forecast (likely NOAA).  The screen is split into three sections (clockwise from top left):

  1. A 3D representation of the island and surrounding ocean with cloud layers shown
  2. A plan view of the island showing cloud cover
  3. A standard climate metrics along the bottom with data like wind direction (labeled Horizontal Direction), barometric pressure, etc.

We also see a section labeled “Sectors”, with “Island 1” currently selected (other options include “USA” and “Island 2”…which is suitably mysterious).

Using the software, they are able to pan the views to the area of ocean with an incoming tropical storm.  The map does not show rainfall, wind direction, wind speed, or distance; but the control room seems to have another source of information for that.  They discuss the projected path of the storm while looking at the map.

Missing Information

The park staff relies on the data from weather services of America and Costa Rica, but doesn’t trust their conclusions (Muldoon asks if this storm will swing out of the way at the last second despite projections, “like the last one”).  But the team at Jurassic Park doesn’t have any information on what’s actually happening with the storm.

Unlike local weather stations here in the U.S., or sites like NOAA weather maps, there is in this interface a lack of basic forecasting information like, say, precipitation amount, precipitation type, individual wind speeds inside the storm, direction, etc… Given the deadly, deadly risks inherent in the park, this seems like a significant oversight.

The software has spent a great deal of time rendering a realistic-ish cloud (which, we should note looks foreshadowingly like a human skull), but neglects to give information that is taken for granted by common weather information systems.

Prediction

When the park meteorologist isn’t on duty, or isn’t awake, or has his attention on the Utahraptor trying to smash its way into the control room, the software should provide some basic information to everyone on staff:

  • What does the weather forecast look like over the next few hours and days?

When the weather is likely to be severe, there’s more information, and it needs to urgently get the attention of the park staff.

  • What’s the prediction?
  • Which parts of the park will be hit hardest?
  • Which tours and staff are in the most dangerous areas?
  • How long will the storm be over the island?

If this information tied into mobile apps or Jurassic Park’s wider systems, it could provide alerts to individual staff, tourists, and tours about where they could take shelter.

Make the Information Usable

Reorienting information that is stuck on the bottom bar and shifting it into the 3d visual would lower the cognitive load required to understand everything that’s going on.  Adding in visuals for other weather data (taken for granted in weather systems now) would bring it at least up to standard.

Finally, putting it up on the big monitor either on demand or when it is urgent would make it available to everyone in the control room, instead of just whoever happened to be at the weather monitor. Modern systems would push the information information out to staff and visitors on their mobile devices as well.

With those changes, everyone could see weather in real time to adjust their behavior appropriately (like, say, delaying the tour when there’s a tropical storm an hour south), the programmer could check the systems and paddocks that are going to get hit, and the inactive consoles could do whatever they needed to do.
