The “spectacular” suicide experience from Soylent Green

The thanatorium is a speculative service for assisted suicide in Soylent Green. Suicide and death are not easy topics and I will do my best to address them seriously. Let me first take a moment to direct anyone who is considering or dealing with suicide to please stop reading this and talk to someone about it. I am unqualified to address—and this blog is not the place to work through—such issues.

There are four experiences to look at in the interface and service design of the Thanatorium: The patient, their beneficiaries, the usher to the beneficiaries, and the attendants to the patient. This post is about the patient themselves. Since there aren’t any technological interfaces, this will be a review of the service design from the patient’s and Soylent’s perspectives. If you’re only into this blog for technological interfaces, this is a post to skip, as it’s going to be about set design, lighting, props, signage, and ritual design, among other things.

Sol’s goals

Part of how we measure the efficacy of an experience is by checking whether it helps its user achieve their goals in the ways they would like them achieved. So let’s say that Sol’s goals are to take advantage of the service to have a good death, i.e. to pass painlessly and with dignity, and to have his belongings passed along according to his wishes. He wants psychological comfort as well, which in this case means helping him psychologically transition from the world he is leaving behind by setting up a liminal space for the ceremony, pointing toward notions of eternity and away from the horrible world he is leaving.

“People,” you say? Yeah, screw that. I’m out.

We are going to completely bypass the script question here about why Sol doesn’t bother to communicate to Thorn the Dark Secret in his goodbye note, but then does tell him when he happens to join him at the Thanatorium. That is what it is.

Sol’s experience

After Sol learns that his options are cannibalism or starvation, he makes the decision to die with dignity. To enact this wish, he dresses in his Sunday best, heads to the state-sponsored Thanatorium, officed in a low-rise building at the end of a wide street in downtown New York City.

Authors Islam Abohela and Noel Lavin insightfully note in their 2020 paper, The Height of Future Architecture: Significance of High versus Low Rise Architecture in Science Fiction Films, that the horizontality of this building contrasts earlier, vertical sci-fi visions of the cityscape as lofty and aspirational. In short, the building is in a horizontal repose suitable to its purpose. Further, the bright illumination spilling out from its frosted-glass doors onto the street helps to sell its next-world-ly promise, especially as the terminus of a dark road.

Initial greeting

At Sol’s approach a young worker opens the door and welcomes him. (How did she know of his approach, given the frosted glass? Let’s presume cameras, though we see no hint of this.)

With the door open, Sol feels the air conditioning pouring from inside and says, “It feels good.” She replies, “Yes, sir. Won’t you please come in?” He hesitates a moment with the gravity of it, but proceeds. Inside he walks through a turnstile and the greeter escorts him to one of the intake queues.

Worldbuilding question: The New York City of Soylent Green is oppressively hot and overcrowded. You would imagine that people would want to feel that refreshing cool air themselves, even if they weren’t there to suicide. I would expect people to be laying on the sidewalk there near the doors on the off-chance to feel a cool breeze. But the street leading to the Thanatorium is vacant. Why is this so? You might think well, it’s an authoritarian state, and curfew is probably enforced brutally. But then why is Sol allowed to just amble his way there? It would have been a nice beat to have seen Sol approached by an angry cop and challenged, only to have Sol point up the street to the Thanatorium, to which the cop softens and nods, allowing Sol to continue. This would have signaled that, despite curfew, the Thanatorium is open 24 hours a day, 7 days for “business.”

Intake

Taking a moment to appreciate the set design, the placid blues and non-descript “plop art” backdrops sell this space as a hospital rather than, say, an airport terminal, or church. It could have gone all “heavenly gate” but that would have been too soon in the patient experience, and lacked the personalized immersion that leads to…uh…the ecstasy meat (a gross, backworlded concept introduced in the beneficiaries post). The service keeps its powder dry to maximize that main event and thereby its output. So this design wins for being both familiar to the patients and effective for Soylent.

The film cuts away to show Thorn returning home to find Sol’s goodbye letter, and then running to the Thanatorium. When we cut back to Sol, he is in the middle of answering some questions by the intake staff, i.e. His favorite color and genre of music. Sol responds and the intake personnel marks his answers on a reusable plastic form. Before signing, Sol wants to confirm that the ceremony will last, “A full 20 minutes?”

“Certainly,” comes the reply, “Guaranteed.”

This scriptwriting moment bears a mention. This comes across as a negotiation, but what is being exchanged here? And what could Sol do with a guarantee when he won’t be there in case this mustache reneges on the deal? Nothing, of course, but it really sets up the transactional nature here. One’s death is so cheap in the world of Soylent Green that one can use it as a bargaining chip. Dark.

There’s a lot that we don’t get to examine in this intake experience because the scene is cut, but per Sol’s goals identified above, we have to imagine it would include questions about his beneficiaries and privacy. Additional questions appear in the text below.

Theater 11

The usher comes and retrieves Sol, making small talk and escorting him down halls, past the beneficiaries’ observation room, to “theater 11,” which is the death chamber to which he’s been assigned, with attendants waiting there standing aside a bed in the center of the room. The inclusion of “11” reminds us that there are many such theaters in the Thanatorium. It would have been nice for the beneficiaries only room to have had a similar number, i.e. “Observation 11: beneficiaries only,” linking the two together for the users and the audience.

We’ll get back to Sol’s experience in a moment, but first a note on the floor markings and the architecture.

I first thought the red line on the floor might have been wayfinding lines like you see in some hospitals. If it was a particularly busy day, and the patient ambulatory, the intake personnel could say, “Follow the red line on the floor to theater 11.” But, a glance at the scenes that precede this show that these markings are only present in the antechamber leading into the theater and the theater itself. So it serves as more of a decoration, a red line leading to a red circle in the middle of which is a white gray, and black circle. The end of the line in two senses.

This sense of the terminus is reinforced by the design of the room. The small passageway down which Sol walks joins with the more expansive theater, creating a sort of “reverse womb” implying a balance between the beginning and end of life. It’s not critical that patients pick up on any of this, of course, but all contributes to a sense of liminality; of interest to both Sol and Soylent.

So all good, but I wish the lighting here had echoed the approach to the building. It should have been a glowing pool of light at the end of a dark passageway, rather than the even overhead lighting reminiscent of a school cafeteria that we see in the film. Pools of light in the center combined with many flickering pinpoints of light at the periphery would have increased the sense of other-worldliness and unified the approach to the building with the entrance to the theater, creating a rhythm of self-similar spectacle. It also would have let the scale of the 180° screen become apparent only once the ceremony started, adding to its thrill and overwhelming scale.

The attendant behavior

In service design, the behavior of the frontstage staff is of particular concern, as humans are good at reading other humans for cues about unfamiliar things. In this case, the attendants are silent, wear beatific expressions, and move with a dance-like deliberateness throughout their parts. It is perhaps the most effective cue-of-transition for the patient. The outfits are a little goofy, but borrow semantically from western Christian liturgy, so are kind-of appropriate. If the patient were atheist or from a different religious tradition, other costumes with different signifiers would be more appropriate.

It’s also of note that not everyone is comfortable with being touched by strangers. It signals a warmth in the scene, but might feel threatening to some patients. Another question to add to the intake questionnaire.

Disrobing

Once Sol is in the theater, the attendants greet him with silent handshakes, lead him to the bed, and begin to help him disrobe. This segment bears many questions.

Why does he need to be naked?

I get why he is disrobed here, from Soylent’s perspective. I’ve never been a mortician, but it does seem that getting the clothes off of a living person would be easier than getting it off a dead person, why make the task harder for Soylent employees down the line? Just work it into the ceremony, some product manager says. And from Sol’s perspective, he’d like to see his clothes being taken away in a nice basket with some assurances that the clothes would be washed and given back to the community; an additional assurance that he’s doing a good, selfless thing in this world with dwindling resources.

But then there are the pants. Maybe it’s me, but there is not a dignified way to remove one’s pants around other, clothed, people. Did they help him out of his pants? Did he do that and just hand the clothes to them? Is he just in his underwear? All of it seems awkward.

I think the service could take a privacy clue from hospitals, public pools, and spas: provide a small room where a patient can undress themselves and switch into a robe. This would also be an opportunity to get a shower, which the movie demonstrates is a cherished luxury in the world of Soylent Green, another reward to lure citizens. Water is in short supply in the world of Soylent Green, but the corpses that are sent en masse to The Exchange for processing don’t get otherwise cleaned, so it would be another nice, hygienic worldbuilding hint.

In the scene, the disrobing is taken as a solemn moment, but Sol is distracted from thinking too hard about it by the appearance of an orange floodlight.

That orange floodlight

During the disrobing, a floodlight of Sol’s favorite color illuminates. I complained briefly about this in the prior post, but what’s causing this light to come on? The usher is back at intake, so it’s not him. Maybe the light is on a timer, but that seems hard for the attendants to manage against the other things that need to happen.

Also, why does it come on at this moment in the ceremony? It might be a deliberate distraction for Sol, meant to focus his attention on the meaning of the ceremony rather than the mundane disrobing, but if so, you might think that the light should illuminate before the disrobing begins. But recall that it’s only happenstance that Sol’s favorite color is the warm and flattering orange. If a patient’s favorite color happened to be blue—which is the most popular color around the world—it would grant everything in theater 11 a cool, detached appearance, and give the patient’s own skin a deathly pallor. Not great for the experience.

Much better would be to keep the custom-color flood light off until the overture begins—when the patient’s attention is not drawn to themselves but focused on the chamber around them—and illuminate it with the rise of the music, in response to the usher’s controls. This would maximize the impact of the color on Sol’s emotional state while not making his own skin and the attendants look off-putting.

Getting onto the bed

Once disrobed, the attendants help Sol onto the bed. How they do this is left off-screen, but it’s a non-trivial problem since as you can see in the screen shot, Sol is 5’7″ and the bed height is well above his waist. Hopefully there’s a set of retractable steps under the bed skirt that can make this accessible to Sol without his having to be hoisted up by the attendants, which would be undignified.

Hemlock

Once in bed, the attendants provide the “hemlock,” (which is what I’m calling the deadly draught they provide in homage to the death of Socrates) and Sol drinks.

We don’t see the glass in the room prior to its being handed to him, but I imagine since this is the point of no return, it bears some attention. Should it be waiting already poured, or should he watch it being poured? Should be pour it himself? If poured, should it be from a gold, porcelain, or glass pitcher? Should there be a tray? Where should all this be staged?

For materials, gold is a good funereal symbol for never tarnishing, but might be too tempting a theft target for poverty-stricken citizens. Stoneware has a nice connotation of being of-the-earth, but is a poor choice for being opaque and here implying its contents are something to be hidden. So I’d recommend a simple glass pitcher that emphasizes clarity. The Toyo pitcher shown below has no handle and so requires two hands to operate, granting a ceremonial, human feel to the act of pouring. While we’re at it, ditch the footed highball glass for a stange or zombie glass to match the pitcher’s simplicity. Have them sitting on an end table on a tray at the side of the bed in their own pool of light and have the attendant pour and hand the glass to the patient. When they depart the chamber one attendant can take the tray out with them for cleaning, and the other can push the end table back under the bed.

Another argument for delaying the floodlight until the overture is that light can change the apparent color of the drink. It just so happens that Sol’s orange flatters the amber color of the draught, but if his favorite color had been, say, red, it might have made the drink look like a wicked ink. Keep the floodlight off to keep the apparent color of the drink something pleasant and unthreatening.

Sol makes no expression in response to the taste of the hemlock, so we have no clue how it’s flavored, but it’s in everyone’s interest that it be palatable, if not pleasant. It would have been a nice touch at intake to ask him to select from a menu of favorite flavors as well, especially to hide the taste of whatever other drugs need to be mixed in.

Once Sol has imbibed the draught, he lies back on the wedge pillow and the attendants draw a sheet up to his chest.

As the orange floodlight dims to a candlelight whisper, Sol waits for the overture to begin as the attendants depart.

Overture

Alone at last, Sol is treated to an audio overture as the drugs work through his system. The music is the principal theme from the first movement of Tchaikovsky’s Symphony No. 6, the “Pathétique.” He stares up at the ceiling, bathed in his favorite color, listening to his favorite music unaware that things are about to become even more spectacular.

Cinerama

The overture complete (and, per my ecstasy meat theory, the MDMA and opiates have kicked in) the audio-visual presentation starts. The music changes to the first movement of Beethoven’s “Symphony #6 (The Pastoral),” and a very wide-angle video presentation begins on the wrap-around screen above him, starting with a verdant field of tulips blowing in a breeze.

The tiny angles in the screen edge hint that this is meant to work exactly like Cinerama with multiple projectors and stitched edges, though the lack of deformation and perspective in the images is all wrong.

It later transitions to images of fauna, other flora, wholesome livestock, and sunsets—all romantic scenes of a highly-selective-memory of Earth’s heyday. It’s important to remember that audiences in 1973 may have heard of a Cinerama display like this, but few of them had seen it. And the 180+° screen seen in the film dwarfs the original Cinerama 2.65:1 display ratio. So though folks today may yawn at this in comparison to IMAX or Oculus AR displays, at the time this would have seemed very sci-fi.

From our vantage point, it all seems a little cruel, bathing Sol in scenes of what he cannot have and what for him will never be, but maybe it points at an afterlife where the things you recall fondly will be yours again, in abundance. (Hey that seems like a formula for every afterlife story.) Mixed with the drugs in Sol’s system, it would help flood his mind and body with euphoria and all the pleasant neurotransmitters that entails.

I minimize this gif because it is so freaking distracting, as it would be to users.

At a few minutes into the presentation, the SPEAKING PERMITTED light of the beneficiaries interface begins blinking, and the patient is able to talk to their loved ones. This would interrupt the spectacle of the display, but add a flood of additional emotions (and thereby hormones) from heartfelt declarations of love and farewell. Immediately afterward “Morning Mood” from Grieg’s “Peer Gynt Suite #1” plays as biophilic videos play: Alpine mountainscapes with grazing donkeys, tarns with floral banks. Finally it segues to scenes depicting the end-of-a-day: A sunset over waves crashing on the black rocks of a pristine West Coast beach, another sun sets through gaps in swiftly drifting clouds.

The screen fades to black as “Aase’s Death” plays from the “Peer Gynt Suite.” In the film, this is the point where Sol shares the Dark Secret and tells Thorn he must go the Exchange and provide proof to the elders. (Ugh. Screenwriters, again, if this was so important, why did he wait until this moment—which he was not sure would come—to convey this information? It makes no sense. But I digress.)

Psst…did you know the namesake of the James Webb telescope was a filthy homophobe? Now you do.

The camera is all close up in their faces for this final beat, so we don’t know what is playing on the screen, but I’d like to think it’s images of stars and nebulae to evoke not just the end of a terrestrial day, but a connection to things that by comparison seem eternal, everlasting.

Communication signals

The dialogue makes me realize another signal is missing for Sol, that is, how does he know when the audio channel to the observation room is open? Now, it would be nice if the audio channel were tied to the state of the viewing portal. That is, audio is connected when the portal is open and they can see each other; and off when the portal is closed. But, we know that Soylent wants the usher to have control of the channels to silence either party at will, so in lieu of that, let’s give some signal to Sol near the observation window to let him know when the audio channel is open. It should look akin to the interface on the other side in the observation room, but it would have to be redesigned for a 10-foot rather than 2-foot experience. It would also have to not be distracting to the patient when their attention is on the cinerama, so a dim, backlit visual might be enough for sighted users. Separate and custom-designed rooms should be built for differently abled patients.

After his plea to Thorn, Sol finally passes, marking the end of his experience with the Thanatorium.


All told, Sol’s experience suits his goals fairly well. He wants a sense of dignity, spectacle, importance, connection to his loved one, and otherworldliness that he receives. There are little things to fix throughout, as mentioned in the text.

My biggest criticism is of being physically separated from loved ones, when a held hand might take the edge off of the fear of death and add a nice dose of oxytocin to the result, but Soylent’s interest is more about maximizing control of the end product, so this, full of risk, would not make it into the final design.

The Thanatorium: A beneficiary’s experience

The thanatorium is a speculative service for assisted suicide in Soylent Green. Suicide and death are not easy topics and I will do my best to address them seriously. Let me first take a moment to direct anyone who is considering or dealing with suicide to please stop reading this and talk to someone about it. I am unqualified to address—and this blog is not the place to work through—such issues.

There are four experiences to look at in the interface and service design of the Thanatorium: The patient, their beneficiaries, the usher, and the attendants to the patient. This post is about the least complicated of the bunch, the beneficiaries.

Thorn’s experience

We have to do a little extrapolation here because the way we see it in the movie is not the way we imagine it would work normally. What we see is Thorn entering the building and telling staff there to take him to Sol. He is escorted to an observation room labeled “beneficiaries only” by an usher. (Details about the powerful worldbuilding present in this label can be found in the prior post.) Sol has already drunk the “hemlock” drink by the time Thorn enters this room, so Sol is already dying and the robed room attendants have already left.

Aaand I just noticed that the walls are the same color as the Soylent. Ewww.

This room has a window view of the “theater” proper, with an interface mounted just below the window. At the top of this interface is a mounted microphone. Directly below is an intercom speaker beside a large status alert labeled SPEAKING PERMITTED. When we first see the panel this indicator is off. At the bottom is a plug for headphones to the left, a slot for a square authorization key, and in the middle, a row of square, backlit toggle buttons labeled PORTAL, EFFECTS, CHAMBER 2, AUDIO, VISUAL, and CHAMBER 1. When the Sol is mid-show, EFFECTS and VISUAL are the only buttons that are lit.

When the usher closes the viewing window, explaining that it’s against policy for beneficiaries to view the ceremony, Thorn…uh…chokes him in order to persuade him to let him override the policy.

Persuasion.

“Persuaded,” the usher puts his authorization key back in the slot. The window opens again. Thorn observes the ceremony in awe, having never seen the beautiful Earth of Sol’s youth. He mutters “I didn’t know” and “How could I?” as he watches. Sol tries weakly to tell Thorn something, but the speaker starts glitching, with the SPEAKING PERMITTED INDICATOR flashing on and off. Thorn, helpfully, pounds his fist on the panel and demands that the usher do something to fix it. The user gives Thorn wired earbuds and Thorn continues his conversation. (Extradiegetically, is this so they didn’t have to bother with the usher’s overhearing the conversation? I don’t understand this beat.) The SPEAKING PERMITTED light glows a solid red and they finish their conversation.

Yes, that cable jumps back and forth like that in the movie during the glitch. It was a simpler time.

Sol dies, and the lights come up in the chamber. Two assistants come to push the gurney along a track through a hidden door. Some mechanism in the floor catches the gurney, and the cadaver is whisked away from Thorn’s sight.

Regular experience?

So that’s Thorns corrupt, thuggish cop experience of the thanatorium. Let’s now make some educated guesses about what this might imply for the regular, non-thug experience for beneficiaries.

  1. The patient and beneficiaries enter the building and greeted by staff.
  2. They wait in queue in the lobby for their turn.
  3. The patient is taken by attendants to the “theater” and the beneficiaries taken by the usher to the observation room.
  4. Beneficiaries witness the drinking of the hemlock.
  5. The patient has a moment to talk with the beneficiaries and say their final farewells.
  6. The viewing window is closed as the patient watches the “cinerama” display and dies. The beneficiaries wait quietly in the observation room with the usher.
  7. The viewing window is opened as they watch the attendants wheel the body into the portal.
  8. They return to the lobby to sign some documents for benefits and depart.

So, some UX questions/backworlding

We have to backworld some of the design rationales involved to ground critique and design improvements. After all, design is the optimization of a system for a set of effects, and we want to be certain about what effects we’re targeting. So…

Why would beneficiaries be separated from the patient?

I imagine that the patient might take comfort from holding the hands or being near their loved ones (even if that set didn’t perfectly overlap with their beneficiaries). So why is there a separate viewing room? There are a handful of reasons I can imagine, only one of which is really satisfying.

Maybe it’s to prevent the spread of disease? Certainly given our current multiple pandemics, we understand the need for physical separation in a medical setting. But the movie doesn’t make any fuss about disease being a problem (though with 132,000 people crammed into every square mile of the New York City metropolitan area you’d figure it would be), and in Sol’s case, there’s zero evidence in the film that he’s sick. Why does the usher resist the request from Thorn if this was the case? And why wouldn’t the attendants be in some sort of personal protective gear?

Maybe it’s to hide the ugly facts of dying? Real death is more disconcerting to see than most people are familiar with (take the death rattle as one example) and witnessing it might discourage other citizens from opting-in for the same themselves. But, we see that Sol just passes peacefully from the hemlock drink, so this isn’t really at play here.

Maybe it’s to keep the cinerama experience hidden? It’s showing pictures of an old, bountiful earth that—in the diegesis—no longer exists. Thorn says in the movie that he’s too young to know what “old earth” was like, so maybe this society wants to prevent false hope? Or maybe to prevent rioting, should the truth of How Far We’ve Fallen get out? Or maybe it’s considered a reward for patients opting-in to suicide, thereby creating a false scarcity to further incentivize people to opt-in themselves? None of this is super compelling, and we have to ask, why does the usher give in and open the viewport if any of this was the case?

That blue-green in the upper left of this still is the observation booth.

So, maybe it’s to prevent beneficiaries from trying to interfere with the suicide. This society would want impediments against last-minute shouts of, “Wait! Don’t do it!” There’s some slight evidence against this, as when Sol is drinking the Hemlock, the viewing port is wide open, so beneficiaries might have pounded on the window if this was standard operating procedure. But its being open might have been an artifact of Sol’s having walked in without any beneficiaries. Maybe the viewport is ordinarily closed until after the hemlock, opened for final farewells, closed for the cinerama, and opened again to watch as the body is sped away?

Ecstasy Meat

This rationale supports another, more horrible argument. What if the reason is that Soylent (the company) wants the patient to have an uninterrupted dopamine and seratonin hit at the point of dying, so those neurotransmitters are maximally available in the “meat” before processing? (Like how antibiotics get passed along to meat-eaters in industrialized food today.) It would explain why they ask Sol for his favorite color in the lobby. Yes it is for his pleasure, but not for humane reasons. It’s so he can be at his happiest at the point of death. Dopamine and seratonin would make the resulting product, Soylent green, more pleasurable and addictive to consumers. That gives an additional rationale as to why beneficiaries would be prevented from speaking—it would distract from patients’ intense, pleasurable experience of the cinerama.

A quickly-comped up speculative banner ad reading “You want to feel GOOD GOOD. Load up on Soylent Green today!”
Now, with more Clarendon.

For my money, the “ecstasy meat” rationale reinforces and makes worse the movie’s Dark Secret, so I’m going to go with that. Without this rationale, I’d say rewrite the scene so beneficiaries are in the room with the patient. But with this rationale, let’s keep the rooms separate.

Beneficiary interfaces

Which leads us to rethinking this interface.

Beneficiary interfaces

A first usability note is that the SPEAKING PERMITTED indicator is very confusing. The white text on a black background looks like speaking is, currently, permitted. But then the light behind it illuminates and I guess, then speaking is permitted? But wait, the light is red, so does that mean it’s not permitted, or is? And then adding to the confusion, it blinks. Is that the glitching, or some third state? Can we send this to its own interface thanatorium? So to make this indicator more usable, we could do a couple of things.

  • Put a ring of lights around the microphone and grill. When illuminated, speaking is permitted. This presumes that the audience can infer what these lights mean, and isn’t accessible to unsighted users, but I don’t think the audio glitch is a major plot point that needs that much reinforcing; see above. If the execs just have to have it crystal clear, then you could…
  • Have two indicators, one reading SPEAKING PERMITTED and another reading SILENCE PLEASE, with one or the other always lit. If you had to do it on the cheap, they don’t need to be backlit panels, but just two labeled indicator lamps would do.

And no effing blinking.

Thorn voice: NO EFFING BLINKING!

I think part of the affective purpose of the interface is to show how cold and mechanistic the thanatorium’s treatment of people are. To keep that, you could add another indicator light on the panel labeled somewhat cryptically, PATIENT. Have it illuminated until Sol passes, and then have a close up shot when it fades, indicating his death.

Ah, yes, good to have a reminder that’s why he’s a critic and not a working FUI designer.

A note on art direction. It would be in Soylent’s and our-real-world interest to make this interface feel as humane as possible. Maybe less steel and backlit toggles? Then again, this world is operating on fumes, so they would make do with what’s available. So this should also feel a little more strung together, maybe with some wires sticking out held together with electrical tape and tape holding the audio jack in place.

Last note on the accommodations. What are the beneficiaries supposed to do while the patient is watching the cinerama display? Stand there and look awkward? Let’s get some seats in here and pipe the patient’s selection of music in. That way they can listen and think of the patient in the next room.

If you really want it to feel extradiegetically heartless, put a clock on the wall by the viewing window that beneficiaries can check.


Once we simplify this panel and make the room make design sense, we have to figure out what to do with the usher’s interface elements that we’ve just removed, and that’s the next post.

Sci-fi Spacesuits: Biological needs

Spacesuits must support the biological functioning of the astronaut. There are probably damned fine psychological reasons to not show astronauts their own biometric data while on stressful extravehicular missions, but there is the issue of comfort. Even if temperature, pressure, humidity, and oxygen levels are kept within safe ranges by automatic features of the suit, there is still a need for comfort and control inside of that range. If the suit is to be warn a long time, there must be some accommodation for food, water, urination, and defecation. Additionally, the medical and psychological status of the wearer should be monitored to warn of stress states and emergencies.

Unfortunately, the survey doesn’t reveal any interfaces being used to control temperature, pressure, or oxygen levels. There are some for low oxygen level warnings and testing conditions outside the suit, but these are more outputs than interfaces where interactions take place.

There are also no nods to toilet necessities, though in fairness Hollywood eschews this topic a lot.

The one example of sustenance seen in the survey appears in Sunshine, we see Captain Kaneda take a sip from his drinking tube while performing a dangerous repair of the solar shields. This is the only food or drink seen in the survey, and it is a simple mechanical interface, held in place by material strength in such a way that he needs only to tilt his head to take a drink.

Similarly, in Sunshine, when Capa and Kaneda perform EVA to repair broken solar shields, Cassie tells Capa to relax because he is using up too much oxygen. We see a brief view of her bank of screens that include his biometrics.

Remote monitoring of people in spacesuits is common enough to be a trope, but has been discussed already in the Medical chapter in Make It So, for more on biometrics in sci-fi.

Crowe’s medical monitor in Aliens (1986).

There are some non-interface biological signals for observers. In the movie Alien, as the landing party investigates the xenomorph eggs, we can see that the suit outgases something like steam—slower than exhalations, but regular. Though not presented as such, the suit certainly confirms for any onlooker that the wearer is breathing and the suit functioning.

Given that sci-fi technology glows, it is no surprise to see that lots and lots of spacesuits have glowing bits on the exterior. Though nothing yet in the survey tells us what these lights might be for, it stands to reason that one purpose might be as a simple and immediate line-of-sight status indicator. When things are glowing steadily, it means the life support functions are working smoothly. A blinking red alert on the surface of a spacesuit could draw attention to the individual with the problem, and make finding them easier.

Emergency deployment

One nifty thing that sci-fi can do (but we can’t yet in the real world) is deploy biology-protecting tech at the touch of a button. We see this in the Marvel Cinematic Universe with Starlord’s helmet.

If such tech was available, you’d imagine that it would have some smart sensors to know when it must automatically deploy (sudden loss of oxygen or dangerous impurities in the air), but we don’t see it. But given this speculative tech, one can imagine it working for a whole spacesuit and not just a helmet. It might speed up scenes like this.

What do we see in the real world?

Are there real-world controls that sci-fi is missing? Let’s turn to NASA’s space suits to compare.

The Primary Life-Support System (PLSS) is the complex spacesuit subsystem that provides the life support to the astronaut, and biomedical telemetry back to control. Its main components are the closed-loop oxygen-ventilation system for cycling and recycling oxygen, the moisture (sweat and breath) removal system, and the feedwater system for cooling.

The only “biology” controls that the spacewalker has for these systems are a few on the Display and Control Module (DCM) on the front of the suit. They are the cooling control valve, the oxygen actuator slider, and the fan switch. Only the first is explicitly to control comfort. Other systems, such as pressure, are designed to maintain ideal conditions automatically. Other controls are used for contingency systems for when the automatic systems fail.

Hey, isn’t the text on this thing backwards? Yes, because astronauts can’t look down from inside their helmets, and must view these controls via a wrist mirror. More on this later.

The suit is insulated thoroughly enough that the astronaut’s own body heats the interior, even in complete shade. Because the astronaut’s body constantly adds heat, the suit must be cooled. To do this, the suit cycles water through a Liquid Cooling and Ventilation Garment, which has a fine network of tubes held closely to the astronaut’s skin. Water flows through these tubes and past a sublimator that cools the water with exposure to space. The astronaut can increase or decrease the speed of this flow and thereby the amount to which his body is cooled, by the cooling control valve, a recessed radial valve with fixed positions between 0 (the hottest) and 10 (the coolest), located on the front of the Display Control Module.

The spacewalker does not have EVA access to her biometric data. Sensors measure oxygen consumption and electrocardiograph data and broadcast it to the Mission Control surgeon, who monitors it on her behalf. So whatever the reason is, if it’s good enough for NASA, it’s good enough for the movies.


Back to sci-fi

So, we do see temperature and pressure controls on suits in the real world, which underscores their absence in sci-fi. But, if there hasn’t been any narrative or plot reason for such things to appear in a story, we should not expect them.

The Cookie

In one of the story threads, Matt uses an interface as part of his day job at Smartelligence to wrangle an AI that is the cloned a mind of a client named Greta. Matt has three tasks in this role. 

  1. He has to explain to her that she is an artificial intelligence clone of a real world person’s mind. This is psychologically traumatic, as she has decades of memories as if she were a real person with a real body and full autonomy in the world.
  2. He has to explain how she will do her job: Her responsibilities and tools.
  3. He has to “break” her will and coerce her to faithfully serve her master—who is the the real-world Greta. (The idea is that since virtual Greta is an exact copy, she understands real Greta’s preferences and can perform personal assistant duties flawlessly.)

The AI is housed in a small egg-shaped device with a single blue light camera lens. The combination of the AI and the egg-shaped device is called “The Cookie.” Why it is not called The Egg is a mystery left for the reader, though I hope it is not just for the “Cookie Monster” joke dropped late in the episode.

Zed-Eyes

In the world of “White Christmas”, everyone has a networked brain implant called Zed-Eyes that enables heads-up overlays onto vision, personalized audio, and modifications to environmental sounds. The control hardware is a thin metal circle around a metal click button, separated by a black rubber ring. People can buy the device with different color rings, as we see alternately see metal, blue, and black versions across the episode.

To control the implant, a person slides a finger (thumb is easiest) around the rim of a tiny touch device. Because it responds to sliding across its surface, let’s say the device must use a sensor similar to the one used in The Entire History of You (2011) or the IBM Trackpoint,

A thumb slide cycles through a carousel menu. Sliding can happen both clockwise and counterclockwise. It even works through gloves.

The button selects or executes the selected action. The complete list of carousel menu options we see in the episode are: SearchCameraMusicMailCallMagnifyBlockMapThe particular options change across scenes, so it is context-aware or customizable. We will look at some of the particular functions in later posts. For now, let’s discuss the “platform” that is Zed-eyes. Continue reading

Cyberspace: Newark Copyshop

The transition from Beijing to the Newark copyshop is more involved. After he travels around a bit, he realizes he needs to be looking back in Newark. He “rewinds” using a pull gesture and sees the copyshop’s pyramid. First there is a predominantly blue window that unfolds as if it were paper.

jm-35-copyshop-a-animated

And then the copyshop initial window expands. Like the Beijing hotel, this is a floor plan view, but unlike the hotel it stays two dimensional. It appears that cyberspace works like the current world wide web, with individual servers for each location that can choose what appearance to present to visitors.

Johnny again selects data records, but not with a voice command. The first transition is a window that not only expands but spins as it does so, and makes a strange jump at the end from the centre to the upper left.

Once again Johnny uses the two-handed expansion gesture to see the table view of the records. Continue reading

The Doctor’s Office

image03

The doctor’s office is a stark, concrete room with a single desk framed under large windows and a tall vaulted ceiling.  Two chairs sit on a carpet in front of the desk for patients.  A couple pieces of art and personal photos line the room, but they are overwhelmed by the industrial-ness of the rest of the space.

When the doctor enters, he carries a large folder with the patient’s health information and background on paper.  He then talks with the patient directly, without help from notes or his patient’s folder.

There is no visible computer in the room.

image04

While not a traditional interface, this office is interesting because it lacks any traditional interactive features of a futuristic doctor’s office; things like holograms, giant computer screen walls, and robots are completely absent. Continue reading

Galactica’s Wayfinding

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

Bulkhead Doors

image09

At every major intersection, and at the entrance to each room, the Battlestar Galactica has very large pressure doors.  These doors each have a handle and a large wheel on each side.  During regular operation crewmembers open the door with the handle and close it firmly, but do not spin the wheel.  Occasionally, we see crew using the wheel as a leverage point to close the door.

 

Sealing it off

We never directly see a crewmember spin the wheel on the door after it closes.  While Chief Tyrol is acting as head of damage control, he orders all bulkheads in a section of the ship sealed off.  This order is beyond the typical door closing that we witness day-to-day.

image14

This implies that the door has three modes: Open, Closed, and Sealed.

image08

Crewmembers could use the door most of their day in an open or closed mode, where an easy pull of the handle unlatches the door and allows them to enter or leave quickly.  In an emergency, a closed door could be sealed by spinning the valve wheel on one side of the door.

 

Danger?

As with other parts of the Galactica, the doors are completely manual, and cannot be activated remotely. (Because Cylon hacking made them go network-less.) Someone has to run up to the door in an emergency and seal it off.

One worry is that, because there is a valve wheel on both sides, an untrained crewmember might panic and try to unseal the door by turning it in the wrong direction.  This would endanger the entire crew.

image13  image10

The other worry is that the valve spins along a single axis (we see no evidence either way during the show), requiring the crew to know which side of the door they were on to seal it against a vacuum.  “Righty Tighty, Lefty Loosey” would fail in this instance, and might cause hesitation or accidental unsealing in an actual emergency.

Ideally, the doors would have wheels that spun identically on either side, so that a clockwise spin always sealed the door, and a counter-clockwise spin always unsealed it.

image15

Current water-tight doors have two sides, the ‘important’ side and the ‘unimportant’ side.  The important side faces towards the ‘center’ of the vessel, or the core of the larger block of the ship, and can be sealed off quickly from that side with a wheel and heavy ‘dogs’.

Weathertight doors have a handle-latch on both sides that is connected (much like a doorknob), and can seal/unseal the door from either side.

If there is a technical limitation to that mechanism (unlikely, but possible), then a large and obvious graphic on the door (a clockwise or counterclockwise arrow) could serve to remind the crew which direction of turn sealed the door.  In this case, sealing the door is the primary action to call out because it is the action done under a panic situation, and the action most easily forgotten in the heat of the moment.

Otherwise, the doors could be a danger to the crew: the crew on the ‘safe’ side could seal the door against depressurization, but crew on the ‘unsafe’ side might try to unseal it to save themselves in a panic.

Air pressure might keep the door properly closed in this instance, but it is still a risk.

 

Effective?

image12

We see during the damage control incident that the doors are quickly closed and sealed by the crew, even in an emergency, making the rest of the ship airtight.  This either shows that the doors are effective at their job, or the crew is very well trained for such a situation.

Like the rest of the Galactica, the technology relies on people to work.  A couple hints or minor tweaks to that technology could make the crew’s lives much easier without putting them at danger from the Cylons or the empty void of space.

Captain’s Board

image06

The Captain’s Board is a double hexagon table at the very center of the CIC.  This board serves as a combination of podium and status dashboard for the ship’s Captain.  Often, the ship’s XO or other senior officers will move forward and use a grease pen or replacement transparency sheet to update information on the board.

image05For example, after jumping from their initial position to the fleet supply base in the nebula, Colonel Tigh replaces the map on the ‘left’ side of the board with a new map of the location that the Galactica had just jumped to.  This implies that the Galactica has a cache of maps in the CIC of various parts of the galaxy, or can quickly print them on the fly.

After getting hit by a Cylon fighter’s nuclear missile, Tigh focuses on a central section of the board with a grease pen to mark the parts of the Galactica suffering damage or decompression. The center section of the board has a schematic, top-down view of the Galactica.

During the initial fighting, Lt. Gaeda is called forward to plot the location of Galactica’s combat squadrons on the board.  This hand-drawn method is explicitly used, even when the Dradis system is shown to be functioning.

image07

The transparency sheets are labeled with both a region and a sector: in this case, “Caprica Region, SECT OEL”.  More text fills the bottom of the label: “Battlestar Galactica Starchart…”

Several panels of physical keys and low-resolution displays ring the board, but we never see any characters interacting with them.  They do not appear to change during major events or during shifts in the ship status.

The best use of these small displays would be to access reference data with a quick search or wikipedia-style database.  Given what we see in the show, it is likely that it was just intended as fuigetry.

 

Old School

Charts and maps are an old interface that has been well developed over the course of human history.  Modern ships still use paper charts and maps to track their current location as a backup to GPS.

Given the Galactica’s mission to stay active even in the face of complete technological superiority of the opponent, a map-based backup to the Dradis makes sense in spite of the lack of detailed information it might need to provide.  It is best as, and should be, a worst-case backup.  

Here, the issue becomes the 3-dimensional space that the Galactica inhabits.  The maps do an excellent job of showing relationships in a two dimensional plane, but don’t represent the ‘above’ and ‘below’ at all.  

In those situations, perhaps something like a large fish tank metaphor might work better, but wouldn’t allow for quick plotting of distance and measurements by hand.  Instead, perhaps something more like the Pin Table from the 2000 X-Men movie that could be operated by hand:

image01

It would provide a shake-resistant, physical, no-electricity needed 3-D map of the surrounding area.  Markups could be easily accomplished with a sticky-note-like flag that could attach to the pins.
