Sci-fi Spacesuits: Identification

15 Aug 2021 by Christopher Noessel

Spacesuits are functional items, built largely identically to each other, adhering to engineering specifications rather than individualized fashion. A resulting problem is that it might be difficult to distinguish between multiple, similarly-sized individuals wearing the same suits. This visual identification problem might be small in routine situations:

(Inside the vehicle:) Which of these suits it mine?
What’s the body language of the person currently speaking on comms?
(With a large team performing a manual hull inspection:) Who is that approaching me? If it’s the Fleet Admiral I may need to stand and salute.

But it could quickly become vital in others:

Who’s body is that floating away into space?
Ensign Smith just announced they have a tachyon bomb in their suit. Which one is Ensign Smith?
Who is this on the security footage cutting the phlebotinum conduit?

There a number of ways sci-fi has solved this problem.

Name tags

Especially in harder sci-fi shows, spacewalkers have a name tag on the suit. The type is often so small that you’d need to be quite close to read it, and weird convention has these tags in all-capital letters even though lower-case is easier to read, especially in low light and especially at a distance. And the tags are placed near the breast of the suit, so the spacewalker would also have to be facing you. So all told, not that useful on actual extravehicular missions.

Faces

Screen sci-fi usually gets around the identification problem by having transparent visors. In B-movies and sci-fi illustrations from the 1950s and 60s, the fishbowl helmet was popular, but of course offering little protection, little light control, and weird audio effects for the wearer. Blockbuster movies were mostly a little smarter about it.

Seeing faces allows other spacewalkers/characters (and the audience) to recognize individuals and, to a lesser extent, how their faces synch with their voice and movement. People are generally good at reading the kinesics of faces, so there’s a solid rationale for trying to make transparency work.

Armageddon (1998), The Martian (2015), Prospect (2018)

Face + illumination

As of the 1970s, filmmakers began to add interior lights that illuminate the wearer’s face. This makes lighting them easier, but face illumination is problematic in the real world. If you illuminate the whole face including the eyes, then the spacewalker is partially blinded. If you illuminate the whole face but not the eyes, they get that whole eyeless-skull effect that makes them look super spooky. (Played to effect by director Scott and cinematographer Vanlint in Alien, see below.)

Firefly (2002), Battlestar Galactica (2004), Stargate Universe (2009–2011)

Identification aside: Transparent visors are problematic for other reasons. Permanently-and-perfectly transparent glass risks the spacewalker getting damage from infrared lights or blinded from sudden exposure to nearby suns, or explosions, or engine exhaust ports, etc. etc. This is why NASA helmets have the gold layer on their visors: it lets in visible light and blocks nearly all infrared.

Only in 2001 does the survey show a visor with a manually-adjustable translucency. You can imagine that this would be more safe if it was automatic. Electronics can respond much faster than people, changing in near-real time to keep sudden environmental illumination within safe human ranges.

You can even imagine smarter visors that selectively dim regions (rather than the whole thing), to just block out, say, the nearby solar flare, or to expose the faces of two spacewalkers talking to each other, but I don’t see this in the survey. It’s mostly just transparency and hope nobody realizes these eyeballs would get fried.

So, though seeing faces helps solve some of the identification problem, transparent enclosures don’t make a lot of sense from a real-world perspective. But it’s immediate and emotionally rewarding for audiences to see the actors’ faces, and with easy cinegenic workarounds, I suspect identification-by-face is here in sci-fi for the long haul, at least until a majority of audiences experience spacewalking for themselves and realize how much of an artistic convention this is.

Color

Other shows have taken the notion of identification further, and distinguished wearers by color. Mission to Mars, Interstellar, and Stowaway did this similar to the way NASA does it, i.e. with colored bands around upper arms and sometimes thighs.

Mission to Mars (2000), Interstellar (2014), Stowaway (2021)

Destination Moon, 2001: A Space Odyssey, and Star Trek (2009) provided spacesuits in entirely different colors. (Star Trek even equipped the suits with matching parachutes, though for the pedantic, let’s acknowledge these were “just” upper-atmosphere suits.)The full-suit color certainly makes identification easier at a distance, but seems like it would be more expensive and introduce albedo differences between the suits.

Destination Moon (1950), 2001: A Space Odyssey (1968), Star Trek (2009)

One other note: if the visor is opaque and characters are only relying on the color for identification, it becomes easier for someone to don the suit and “impersonate” its usual wearer to commit spacewalking crimes. Oh. My. Zod. The phlebotinum conduit!

According to the Colour Blind Awareness organisation, blindness (color vision deficiency) affects approximately 1 in 12 men and 1 in 200 women in the world, so is not without its problems, and might need to be combined with bold patterns to be more broadly accessible.

What we don’t see

Heraldry

Blog from another Mog Project Rho tells us that books have suggested heraldry as space suit identifiers. And while it could be a device placed on the chest like medieval suits of armor, it might be made larger, higher contrast, and wraparound to be distinguishable from farther away.

Directional audio

Indirect, but if the soundscape inside the helmet can be directional (like a personal Surround Sound) then different voices can come from the direction of the speaker, helping uniquely identify them by position. If there are two close together and none others to be concerned about, their directions can be shifted to increase their spatial distinction. When no one is speaking leitmotifs assigned to each other spacewalker, with volumes corresponding to distance, could help maintain field awareness.

HUD Map

Gamers might expect a map in a HUD that showed the environment and icons for people with labeled names.

Search

If the spacewalker can have private audio, shouldn’t she just be able to ask, “Who’s that?” while looking at someone and hear a reply or see a label on a HUD? It would also be very useful if I’ve spacewalker could ask for lights to be illuminated on the exterior of another’s suit. Very useful if that other someone is floating unconscious in space.

Mediated Reality Identification

Lastly I didn’t see any mediated reality assists: augmented or virtual reality. Imagine a context-aware and person-aware heads-up display that labeled the people in sight. Technological identification could also incorporate in-suit biometrics to avoid the spacesuit-as-disguise problem. The helmet camera confirms that the face inside Sargeant McBeef’s suit is actually that dastardly Dr. Antagonist!

We could also imagine that the helmet could be completely enclosed, but be virtually transparent. Retinal projectors would provide the appearance of other spacewalkers—from live cameras in their helmets—as if they had fishbowl helmets. Other information would fit the HUD depending on the context, but such labels would enable identification in a way that is more technology-forward and cinegenic. But, of course, all mediated solutions introduce layers of technology that also introduces more potential points of failure, so not a simple choice for the real-world.

Oh, that’s right, he doesn’t do this professionally.

So, as you can read, there’s no slam-dunk solution that meets both cinegenic and real-world needs. Given that so much of our emotional experience is informed by the faces of actors, I expect to see transparent visors in sci-fi for the foreseeable future. But it’s ripe for innovation.

Sci-fi Spacesuits: Audio Comms

3 Aug 2021 by Christopher Noessel

A special subset of spacesuit interfaces is the communication subsystems. I wrote a whole chapter about Communications in Make It So, but spacesuit comms bear special mention, since they’re usually used in close physical proximity but still must be mediated by technology, the channels for detailed control are clumsy and packed, and these communicators are often being overseen by a mission control center of some sort. You’d think this is rich territory, but spoiler: There’s not a lot of variation to study.

Every single spacesuit in the survey has audio. This is so ubiquitous and accepted that, after 1950, no filmmaker has thought the need to explain it or show an interface for it. So you’d think that we’d see a lot of interactions.

*Destination Moon* (1950): Woody learns from the narrator that without air, he needs to extend his radio antenna in order to communicate in space. (Note: You’re not missing something, this live action film had an animated explanatory sequence starring Woody Woodpecker.)

Spacesuit communications in sci-fi tend to be many-to-many with no apparent means of control. Not even a push-to-mute if you sneezed into your mic. It’s as if the spacewalkers were in a group, merely standing near each other in air, chatting. No push-to-talk or volume control is seen. Communication with Mission Control is automatic. No audio cues are given to indicate distance, direction, or source of the sound, or to select a subset of recipients.

The one seeming exception to the many-to-many communication is seen in the reboot of Battlestar Galactica. As Boomer is operating a ship above a ground crew, shining a light down on them for visibility, she has the following conversation with Tyrol.

*Battlestar Galactica* (Season 1, Episode 2, “Water” 2004): Boomer and Tyrol confirm contact with each other.

Tyrol
Raptor 478, this is DC-1, I have you in my sights.
Boomer
Copy that, DC-1. I have you in sight.
Tyrol
Understood.
Boomer
How’s it looking there? Can you tell what happened?
Tyrol
Lieutenant, don’t worry…about my team. I got things under control.
Boomer
Copy that, DC-1. I feel better knowing you’re on it.

Then, when her copilot gives her a look about what she has just said, she says curtly to him, “Watch the light, you’re off target.” In this exchange there is clear evidence that the copilot has heard the first conversation, but it appears that her comment to him is addressed to him and not for the others to hear. Additionally, we do not hear chatter going on between the ground grew during this exchange. Unfortunately, we do not see any of the conversationalists touch a control to give us an idea about how they switch between these modes. So, you know, still nothing.

More recent films, especially in the MCU, has seen all sorts of communication controlled by voice with the magic of General AI…pause for gif…

…but as I mention more and more, once you have a General AI in the picture, we leave the realm of critique-able interactions. Because an AI did it.

In short, sci-fi just doesn’t care about showing audio controls in sci-fi spacesuits, and isn’t likely to start caring anytime soon. As always, if you know of something outside my survey, please mention it.

For reference, in the real world, a NASA astronaut has direct control over the volume of audio that she hears, using potentiometer volume controls. (Curiously the numbers on them are not backwards, unlike the rest of the controls.)

A spacewalker uses the COMM dial switch mode selector at the top of the DCM to select between three different frequencies of wireless communication, each of which broadcasts to each other and the vehicle. When an astronaut is on one of the first two channels, transmission is voice-activated. But a backup, “party line” channel requires push-to-talk, and this is what the push-to-talk control is for.

By default, all audio is broadcast to all other spacewalkers, the vehicle, and Mission Control. To speak privately, without Mission Control hearing, spacewalkers don’t have an engineered option. But if one of the radio frequency bands happens to be suffering a loss of signal to Mission Control, she can use this technological blind spot to talk with some degree of privacy.

Sci-fi Spacesuits: Interface Locations

6 Jul 2021 by Christopher Noessel

A major concern of the design of spacesuits is basic usability and ergonomics. Given the heavy material needed in the suit for protection and the fact that the user is wearing a helmet, where does a designer put an interface so that it is usable?

Chest panels

Chest panels are those that require that the wearer only look down to manipulate. These are in easy range of motion for the wearer’s hands. The main problem with this location is that there is a hard trade off between visibility and bulkiness.

Arm panels

Arm panels are those that are—brace yourself—mounted to the forearm. This placement is within easy reach, but does mean that the arm on which the panel sits cannot be otherwise engaged, and it seems like it would be prone to accidental activation. This is a greater technological challenge than a chest panel to keep components small and thin enough to be unobtrusive. It also provides some interface challenges to squeeze information and controls into a very small, horizontal format. The survey shows only three arm panels.

The first is the numerical panel seen in 2001: A Space Odyssey (thanks for the catch, Josh!). It provides discrete and easy input, but no feedback. There are inter-button ridges to kind of prevent accidental activation, but they’re quite subtle and I’m not sure how effective they’d be.

The second is an oversimplified control panel seen in Star Trek: First Contact, where the output is simply the unlabeled lights underneath the buttons indicating system status.

The third is the mission computers seen on the forearms of the astronauts in Mission to Mars. These full color and nonrectangular displays feature rich, graphic mission information in real time, with textual information on the left and graphic information on the right. Input happens via hard buttons located around the periphery.

*Mission to Mars* (2000): Phil sees that Woody is likely to overshoot

Side note: One nifty analog interface is the forearm mirror. This isn’t an invention of sci-fi, as it is actually on real world EVAs. It costs a lot of propellant or energy to turn a body around in space, but spacewalkers occasionally need to see what’s behind them and the interface on the chest. So spacesuits have mirrors on the forearm to enable a quick view with just arm movement. This was showcased twice in the movie Mission to Mars.

*Mission to Mars* (2000): Phil looks for Earth with his “rear view mirror.” It’s that tiny white dot.

HUDs

The easiest place to see something is directly in front of your eyes, i.e. in a heads-up display, or HUD. HUDs are seen frequently in sci-fi, and increasingly in sc-fi spacesuits as well. One is Sunshine. This HUD provides a real-time view of each other individual to whom the wearer is talking while out on an EVA, and a real-time visualization of dangerous solar winds.

These particular spacesuits are optimized for protection very close to the sun, and the visor is limited to a transparent band set near eye level. These spacewalkers couldn’t look down to see the top of a any interfaces on the suit itself, so the HUD makes a great deal of sense here.

Star Trek: Discovery’s pilot episode included a sequence that found Michael Burnham flying 2000 meters away from the U.S.S. Discovery to investigate a mysterious Macguffin. The HUD helped her with wayfinding, navigating, tracking time before lethal radiation exposure (a biological concern, see the prior post), and even doing a scan of things in her surroundings, most notably a Klingon warrior who appears wearing unfamiliar armor. Reference information sits on the periphery of Michael’s vision, but the augmentations occur mapped to her view. (Noting this raises the same issues of binocular parallax seen in the Iron HUD.)

Star Trek: Discovery (2017–) S01E01, “The Vulcan Hello”

Iron Man’s Mark L armor was able to fly in space, and the Iron HUD came right along with it. Though not designed/built for space, it’s a general AI HUD assisting its spacewalker, so worth including in the sample.

Aside from HUDs, what we see in the survey is similar to what exists in existing real-world extravehicular mobility units (EMUs), i.e. chest panels and arm panels.

Inputs illustrate paradigms

Physical controls range from the provincial switches and dials on the cigarette-girl foldout control panels of Destination Moon to the simple and restrained numerical button panel of 2001, to strangely unlabeled buttons of Star Trek: First Contact’s arm panels (above), and the ham-handed touch screens of Mission to Mars.

*Mission to Mars* (2000): Jim tests the atmosphere and learns it is Earth-like.

As the pictures above reveal, the input panels reflect the familiar technology of the time of the creation of the movie or television show. The 1950s were still rooted in mechanistic paradigms, the late 1960s interfaces were electronic pushbutton, the 2000s had touch screens and miniaturized displays.

Real world interfaces

For comparison and reference, the controls for NASA’s EMU has a control panel on the front, called the Display and Control Module, where most of the controls for the EMU sit.

The image shows that inputs are very different than what we see as inputs in film and television. The controls are large for easy manipulation even with thick gloves, distinct in type and location for confident identification, analog to allow for a minimum of failure points and in-field debugging and maintenance, and well-protected from accidental actuation with guards and deep recesses. The digital display faces up for the convenience of the spacewalker. The interface text is printed backwards so it can be read with the wrist mirror.

The outputs are fairly minimal. They consist of the pressure suit gauge, audio warnings, and the 12-character alphanumeric LCD panel at the top of the DCM. No HUD.

The gauge is mechanical and standard for its type. The audio warnings are a simple warbling tone when something’s awry. The LCD panel provides information about 16 different values that the spacewalker might need, including estimated time of oxygen remaining, actual volume of oxygen remaining, pressure (redundant to the gauge), battery voltage or amperage, and water temperature. To cycle up and down the list, she presses the Mode Selector Switch forward and backward. She can adjust the contrast using the Display Intensity Control potentiometer on the front of the DCM.

The DCMs referenced in the post are from older NASA documents. In more recent images on NASA’s social media, it looks like there have been significant redesigns to the DCM, but so far I haven’t seen details about the new suit’s controls. (Or about how that tiny thing can house all the displays and controls it needs to.)

Sci-fi Spacesuits: Biological needs

24 Jun 2021 by Christopher Noessel

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.

Mission to Mars (2000), McConnell verifies that the team can remove their helmets.

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.

*Sunshine* (2007): Truman asks spacewalker Shelby to calm down since his vital signs are stressed.

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.

*Sunshine* (2007): Cassie warns Capa that he’s using a lot of oxygen.

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.

*Alien* (1979): The away team’s suit exhales as they walk the alien wreckage.
Look for the white plume in the left image and a dark plume on the right.

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.

*The Fifth Element* (1997): Mondoshawan spacesuits have tiny lights along the exterior.

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.

*Guardians of the Galaxy* (2012) ~~Peter~~ Starlord puts his Helmet on Gamora in space outside the Kyln.

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.

Vibranium-based Cape Shields

16 Mar 2021 by Christopher Noessel

Editor’s Note: Today’s guest post is penned by Lonny Brooks. Be sure and read his introduction post if you missed it when it was published.

The Black Panther film represents one of the most ubiquitous statements of Afrofuturist fashion and fashionable digital wearables to celebrate the Africana and Black imagination. The wearable criteria under Director Ryan Cooglar’s lead and that of the formidable talent of costume designer Ruth E. Carter took into account African tribal symbolism. The adinkra symbol, for “cooperation,” emblazoned across W’Kabi’s (played by Daniel Kaluuya) blanket embodies the role of the Border tribe where they lived in a small village tucked into the mountainous borderlands of Wakanda, disguised as farmers and hunters.

Beautiful interaction

Chris’ blog looks at the interactions with speculative technology, and here the interactions are marvelously subtle. They do not have buttons or levers, which might give away their true nature. To activate them, a user does what would come naturally, which is to hold the fabric before them, like a shield. (There might be a mental command as well, but of course we can’t perceive that.) The shield-like gesture activates the shield technology. It’s quick. It fits the material of the technology. You barely even have to be trained to use it. We never see the use case for when a wearer is incapacitated and can’t lift the cape into position, but there’s enough evidence in the rest of the film to expect it might act like Dr. Strange’s cape and activate its shield automatically.

But, for me, the Capes are more powerful not as models of interaction, but for what they symbolize.

The Dual Role of the Capes

The role of the Border Tribe is to create the illusion of agrarian ruggedness as a deception for outsiders that only tells of a placid, developing nation rather than the secret technologically advanced splendor of Wakanda’s lands. The Border Tribe is the keeper of Wakanda’s cloaking technology that hides the vast utopian advancement of Wakandan advantage.

The Border Tribe’s role is built into the fabric of their illustrious and enviably fashionable capes. The adinkra symbol of cooperation embedded into the cape reveals, by the final scenes of the Black Panther film, how the Border Tribe defenders wield their capes into a force field wall of energy to repel enemies.

Ironically we only see them at their most effective when Wakanda is undergoing a civil war between those loyal to Kilmonger who is determined to avenge his father’s murder and his own erasure from Wakandan collective memory, and those supporting King T’Challa. Whereas each Black Panther King has selected to keep Wakanda’s presence hidden literally under the cooperative shields of the Border Tribe, Kilmonger—an Oakland native and a potential heir to Wakandan monarchy—was orphaned and left in the U.S.

If this sounds familiar, consider the film as a grand allusion to the millions of Africans kidnapped and ripped from their tribal lineages and taken across the Atlantic as slaves. Their cultural heritage was purposefully erased, languages and tribal customs, memories lost to the colonial thirst for their unpaid and forced labor.

Kilmonger represents the Black Diaspora, former descendants of African homelands similarly deprived of their birthrights. Kilmonger wants the Black Diaspora to rise up in global rebellion with the assistance of Wakandan technical superiority. In opposition, King T’Challa aspires for a less vengeful solution. He wantsWakanda to come out to the world, and lead by example. We can empathize with both. T’Challa’s plan is fueled by virtue. Kilmonger’s is fueled by justice—redeploy these shields to protect Black people against the onslaught of ongoing police and state violence.

W. E. B. Du Bois in 1918
(image in the public domain)

Double Consciousness and the Big Metaphor

The cape shields powered by the precious secret meteorite called Vibranium embodies what the scholar W.E.B. Dubois referred to as a double consciousness, where members of the Black Diaspora inhabit two selves.

Their own identity as individuals
The external perception of themselves as a members of an oppressed people incessantly facing potential erasure and brutality.

The cape shields and their cloaking technology cover the secret utopic algorithms that power Wakanda, while playing on the petty stereotypes of African nations as less-advanced collectives.

The final battle scene symbolizes this grand debate—between Kilmonger’s claims on Wakanda and assertion of Africana power, and King T’Challa’s more cooperative and, indeed, compliant approach working with the CIA. Recall that in its subterfuge and cloaking tactics, the CIA has undermined and toppled numerous freely-elected African and Latin American governments for decades. In this final showdown, we see W’Kabi’s cloaked soldiers run down the hill towards King T’Challa and stop to raise their shields cooperatively into defensive formation to prevent King T’Challa’s advance. King T’Challa jumps over the shields and the force of his movement causes the soldier’s shields to bounce away while simultaneously revealing their potent energy.

The flowing blue capes of the Border Tribe are deceptively enticing, while holding the key to Wakanda’s survival as metaphors for cloaking their entire civilization from being attacked, plundered, and erased. Wakanda and these capes represent an alternative history: What if African peoples had not experienced colonization or undergone the brutal Middle Passage to the Americas? What if the prosperous Black Greenwood neighborhood of Tulsa, Oklahoma had developed cape shield technology to defend themselves against a genocidal white mob in 1921? Or if the Black Panther Party had harnessed the power of invisible cloaking technology as part of their black beret ensemble?

In the forecasting imagination game, Afro-Rithms From The Future, and the game event we played in 2019 in Los Angeles based on the future universe we created, we generated the question:

What would be an article of fashion that would give you more Black Feminist leadership and more social justice?

One participant responded with: “I was thinking of the notion of the invisibility cloak but also to have it be reversed. It could make you invisible and also more visible, amplifying what you normally” have as strengths and recognizing their value. Or as another player, states “what about a bodysuit that protects you from any kind of harm” or as the game facilitator adds “how about a bodysuit that repels emotional damage?!” In our final analysis, the cape shields have steadfastly protected Wakanda against the emotional trauma of colonization and partial erasure.

In this way the cape shields guard against emotional damage as well. Imagine how it might feel to wear a fashionable cloak that displays images of your ancestral, ethnic, and gender memories reminding you of your inherent lovability as multi-dimensional human being—and that can technologically protect you and those you love as well.

Okoye’s grip shoes

5 Jan 2021 by Christopher Noessel

Like so much of the tech in Black Panther, this wearable battle gear is quite subtle, but critical to the scene, and much more than it seems at first. When Okoye and Nakia are chasing Klaue through the streets of Busan, South Korea, she realizes she would be better positioned on top of their car than within it.

She holds one of her spears out of the window, stabs it into the roof, and uses it to pull herself out on top of the swerving, speeding car. Once there, she places her feet into position, and the moment the sole of her foot touches the roof, it glows cyan for a moment.

She then holds onto the stuck spear to stabilize herself, rears back with her other spear, and throws it forward through the rear-window and windshield of some minions’ car, where it sticks in the road before them. Their car strikes the spear and get crushed. It’s a kickass moment in a film of kickass moments. But by all means let’s talk about the footwear.

Now, it’s not explicit, the effect the shoe has in the world of the story. But we can guess, given the context, that we are meant to believe the shoes grip the car roof, giving her a firm enough anchor to stay on top of the car and not tumble off when it swerves.

She can’t just be stuck

I have never thrown a javelin or a hyper-technological vibranium spear. But Mike Barber, PhD scholar in Biomechanics at Victoria University and Australian Institute of Sport, wrote this article about the mechanics of javelin throwing, and it seems that achieving throwing force is not just by sheer strength of the rotator cuff. Rather, the thrower builds force across their entire body and whips the momentum around their shoulder joint.

Okoye is a world-class warrior, but doesn’t have superpowers, so…while I understand she does not want the car to yank itself from underneath her with a swerve, it seems that being anchored in place, like some Wakandan air tube dancer, will not help her with her mighty spear throwing. She needs to move.

It can’t just be manual

Imagine being on a mechanical bull jerking side to side—being stuck might help you stay upright. But imagine it jerking forward suddenly, and you’d wind up on your butt. If it jerked backwards, you’d be thrown forward, and it might be much worse. All are possibilities in the car chase scenario.

If those jerking motions happened to Okoye faster than she could react and release her shoes, it could be disastrous. So it can’t be a thing she needs to manually control. Which means it needs to some blend of manual, agentive, and assistant. Autonomic, maybe, to borrow the term from physiology?

So…

To really be of help, it has to…

monitor the car’s motion
monitor her center of balance
monitor her intentions
predict the future motions of the cars
handle all the cybernetics math (in the Norbert Wiener sense, not the sci-fi sense)
know when it should just hold her feet in place, and when it should signal for her to take action
know what action she should ideally take, so it knows what to nudge her to do

These are no mean feats, especially in real-time. So, I don’t see any explanation except…

AGI is in the Wakandan arsenal (c.f. Griot helping Ross), so this is credible given the diegesis, but I did not expect to find it in shoes.

An interesting design question is how it might deliver warning signals about predicted motions. Is it tangible, like vibration? Or a mild electrical buzz? Or a writing-to-the-brain urge to move? The movie gives us no clues, but if you’re up for a design challenge, give it a speculative design pass.

Wearable heuristics

As part of my 2014 series about wearable technologies in sci-fi, I identified a set of heuristics we can use to evaluate such things. A quick check against those show that they fare well. The shoes are quite sartorial, and look like shoes so are social as well. As a brain interface, it is supremely easy to access and use. Two of the heuristics raise questions though.

Wearables must be designed so they are difficult to accidentally activate. It would have been very inconvenient for Okoye to find herself stuck to the surface of Wakanda while trying to chase Killmonger later in the film, for example. It would be safer to ensure deliberateness with some mode-confirming physical gesture, but there’s no evidence of it in the movie.
Wearables should have apposite I/O. The soles glow. Okoye doesn’t need that information. I’d say in a combat situation it’s genuinely bad design to require her to look down to confirm any modes of the shoes. They’re worn. She will immediately feel whether her shoes are fixed in place. While I can’t name exactly how an enemy might use the knowledge about whether she is stuck in place or not, but on general principle, the less information we give to the enemy, the safer you’ll be. So if this was real-world, we would seek to eliminate the glow. That said, we know that undetectable interactions are not cinegenic in the slightest, so for the film this is a nice “throwaway” addition to the cache of amazing Wakandan technology.

Black Georgia Matters and Today is the Day

Each post in the Black Panther review is followed by actions that you can take to support black lives.

Today is the last day in the Georgia runoff elections. It’s hard to overstate how important this is. If Ossoff and Warnock win, the future of the country has a much better likelihood of taking Black Lives Matter (and lots of other issues) more seriously. Actual progress might be made. Without it, the obstructionist and increasingly-frankly-racist Republican party (and Moscow Mitch) will hold much of the Biden-Harris administration back. If you know of any Georgians, please check with them today to see if they voted in the runoff election. If not—and they’re going to vote Democrat—see what encouragement and help you can give them.

Some ideas…

Pay for a ride there and back remotely.
Buy a meal to be delivered for their family.
Make sure they are protected and well-masked.
Encourage them to check their absentee ballot, if they cast one, here. https://georgia.ballottrax.net/voter/
If their absentee ballot has not been registered, they can go to the polls and tell the workers there that they want to cancel their absentee ballot and vote in person. Help them know their poll at My Voter Page: https://www.mvp.sos.ga.gov/MVP/mvp.do

This vote matters, matters, matters.

Kimoyo Beads

3 Nov 2020 by Christopher Noessel

One of the ubiquitous technologies seen in Black Panther is the kimoyo bead. They’re liberally scattered all over the movie like tasty, high-tech croutons. These marble-sized beads are made of vibranium and are more core to Wakandan’s lives than cell phones are to ours. Let’s review the 6 uses seen in the film.

1. Contact-EMP bombs

We first see kimoyo beads when Okoye equips T’Challa with a handful to drop on the kidnapper caravan in the Sambisa forest. As he leaps from the Royal Talon, he flings these, which flatten as they fall, and guide themselves to land on the hoods of the caravan. There they emit an electromagnetic pulse that stops the vehicles in their tracks. It is a nice interaction that does not require much precision or attention from T’Challa.

2. Comms

Wakandans wear bracelets made of 11 kimoyo beads around their wrists. If they pull the comms bead and place it in the palm, it can project very lifelike volumetric displays as part of realtime communication. It is unclear why the bead can’t just stay on the wrist and project at an angle to be facing the user’s line of sight, as it does when Okoye presents to tribal leaders (below.)

We see a fascinating interaction when T’Challa and W’Kabi receive a call at the same time, and put their bracelets together to create a conference call with Okoye.

The scaled-down version of the projection introduces many of the gaze matching problems identified in the book. Similarly to those scenes in Star Wars, we don’t see the conversation from the other side. Is Okoye looking up at giant heads of T’Challa and W’Kabi? Unlikely. Wakanda is advanced enough to manage gaze correction in such displays.

Let me take a moment to appreciate how clever this interaction is from a movie maker’s perspective. It’s easy to imagine each of them holding their own bead separately and talking to individual instances of Okoye’s projection. (Imagine being in a room with a friend and both of you are on a group call with a third party.) But in the scene, she turns to address both T’Challa and W’Kabi. Since the system is doing body-and-face gaze correction, the two VP displays would look slightly different, possibly confusing the audience into thinking these were two separate people on the call. Wakandans would be used to understanding these nuances, but us poor non-Wakandan’s are not.

Identical Okoyes ensures (at least) one of the displays is looking at something weird. It’s confusing. — This is confusing.

Having gaze correction so both Okoyes are looking at T’Challa when she’s talking to him makes it look like there are two different characters. It’s confusing. — This is also confusing.

The shared-display interaction helps bypass these problems and make the technology immediately understandable and seamless.

Later Shuri also speaks with Okoye via communication bead. During this conversation, Shuri removes another bead, and tosses it into a display to show an image and dossier of Killmonger. Given that she’s in her lab, it’s unclear why this gesture is necessary rather than, say, just looking toward a display and thinking, “Show me,” letting the AI Griot interpret from the context what to display.

A final communication happens immediately after as Shuri summons T’Challa to the the lab to learn about Killmonger. In this screenshot, it’s clear that the symbol for the comms bead is an asterisk or star, which mimics the projection rats of the display, and so has some nice semantics to help users learning which symbols do what.

3. Presentation

In one scene, Okoye gives the tribe rulers a sitrep using her kimoyo beads as a projector. Here she is showing the stolen Wakandan artifact. Readers of the book will note the appearance of projection rays that are standard sci-fi signals that what is seen is a display. A lovely detail in the scene is how Okoye uses a finger on her free hand to change the “slide” to display Klawe. (It’s hard to see the exact gesture, but looks like she presses the projection bead.) We know from other scenes in the movie that the beads are operated by thought-command. But that would not prevent a user from including gestures as part of the brain pattern that triggers an event, and would make a nice second-channel confirmation as discussed in UX of Speculative Brain-Computer Inputs post.

4. Remote piloting

When T’Challa tours Shuri’s lab, she introduces him to remote access kimoyo beads. They are a little bigger than regular beads and have a flared, articulated base. (Why they can’t just morph mid-air like the ones we see in the kidnapper scene?) These play out in the following scene when the strike team needs to commandeer a car to chase Klawe’s Karavan. Oyoke tosses one on the hood on a parked car, its base glows purple, and thereafter Shuri hops into a vibranium-shaped simulacrum of the car in her lab, and remotely operates it.

A quick note: I know that the purple glow is there for the benefit of the audience, but it certainly draws attention to itself, which it might not want to do in the real world.

In the climactic battle of the tribes with Killmonger, Shuri prints a new bracelet and remote control bead for Agent Ross. She places the bracelet on him to enable him to remote pilot the Royal Talon. It goes by very quickly, and the scene is lit quite sparsely, but the moment she puts it on him, you can see that the beads are held together magnetically.

5. Eavesdropping

When Agent Ross is interrogating the captured Klawe, we get a half-second shot to let us know that a kimoyo bead has been placed on his shoulder, allowing T’Challa, Okoye, and Nakia to eavesdrop on the conversation. The output is deliveredby a flattened bone-conducting speaker bead behind their left hears.

6. Healing

Later in the scene, when Killmonger’s bomb grievously wounds Agent Ross in his spine, T’Challa places one of Nakia’s kimoyo beads onto the wound, stabilizing Ross long enough to ferry him to Wakanda where Shuri can fully tend to him. The wound conveniently happens to be kimoyo-bead sized, but I expect that given its shape-shifting powers, it could morph to form a second-skin over larger wounds.

I wondered if kimoyo beads were just given to Wakandan royalty, but it’s made clear in the scene where T’Challa and Nakia walk through the streets of Birnin Zana that every citizen has a bracelet. There is no direct evidence in the film, but given the pro-social-ness throughout, I want to believe that all citizens have free access to the beads, equipping each of them to participate equitably in the culture.

So, most of the interaction is handled through thought-command with gestural augmentation. This means that most of our usual concerns of affordances and constraints are moot. The one thing that bears some comment is the fact that there are multiple beads on the bracelet with different capabilities. How does a user know which bead does what?

As long as the beads can do their job in place on the wrist, I don’t think it matters. As long as all of the beads are reading the user’s thoughts, only the one that can respond need respond. The others can disregard the input. In the real world you’d need to make sure that one thought isn’t interpretable as multiple things, a problem discussed on my team at IBM as disambiguation. Or if they are you must design an interaction where the user can help disambiguate the input, or tell the system which meaning they intend. We never this edge case in Black Panther.

It seems that some of the beads have specialized functions that cannot be performed by another, each has several symbols engraved into it, the indentions of which glow white for easy identification. The glow is not persistent across all uses, so it must be either context-aware and/or a setting that users can think to change. But even when not lit, the symbols are clear, and clearly distinguishable, so once the user learns the symbols, the labeling should help.

Black Votes Matter

Today is an important day in the United States. It’s election day 2020. Among one of the most important days in U.S. politics, ever. Among Trump’s litany of outrageous lies across his presidency is this whopper: “I have done more for Black Americans than anybody, except for the possible exception of Abraham Lincoln.” (Pause for your spit take and cleaning your screen.)

As infuriating and insulting as this statement is emotionally (like, fuck you for adding “possible” in there, like it’s somehow possible that you’ve done more than freed our black citizens from slavery, you maggot-brained, racist, malignant narccicist) let’s let the Brookings institute break down why, if you believe Black Lives Matter, you need to get out there and vote blue all the way down the ticket.

https://www.cnn.com/2020/11/02/us/ocoee-massacre-100th-anniversary-trnd/index.html

You should read that whole article, but some highlights/reminders

Trump ended racial sensitivity training, and put a ban on trainings that utilize critical race theory
Hate crimes increased over 200% in places where Trump held a campaign rally in 2016
He dismissed the Black Lives Matters movement, said there were “fine people” among white supremacist groups, and rather than condemning the (racist, not gay) Proud Boys, told them to “stand by.”
Not a single one of his 53 confirmed appeals court judges circuit justices is black.
The criminal mishandling of the COVID-19 pandemic has killed twice as many black Americans as it has white Americans. (Don’t forget he fired the pandemic response team.)

If you are reading this on election day, and have not already done so, please go vote blue. Know that if you are in line even when the polls officially closed, they have to stay open for the entire line to vote. If you have voted, please help others in need. More information is below.

If you are reading this just after election day, we have every evidence that Trump is going to try and declare the election rigged if he loses (please, please let it be when he loses to a massive blue waver). You can help set the expectation among your circle of friends, family, and work colleagues that we won’t know the final results today. We won’t know it tomorrow. We may have a better picture at the end of the week, but it will more likely take until late November to count everyone’s vote, and possibly until mid December to certify everyone’s vote.

And that’s what we do in a liberal democracy. We count everyone’s vote, however long that takes. To demand it in one day during a pandemic is worse than a toddler throwing a “I want it now” tantrum. And we are so very sick of having a toddler in this position.

The Royal Talon piloting interface

7 Sep 2020 by Christopher Noessel

Since my last post, news broke that Chadwick Boseman has passed away after a four year battle with cancer. He kept his struggles private, so the news was sudden and hard-hitting. The fandom is still reeling. Black people, especially, have lost a powerful, inspirational figure. The world has also lost a courageous and talented young actor. Rise in Power, Mr. Boseman. Thank you for your integrity, bearing, and strength.

Black Panther’s airship is a triangular vertical-takeoff-and-landing vehicle called the Royal Talon. We see its piloting interface twice in the film.

The first time is near the beginning of the movie. Okoye and T’Challa are flying at night over the Sambisa forest in Nigeria. Okoye sits in the pilot’s seat in a meditative posture, facing a large forward-facing bridge window with a heads up display. A horseshoe-shaped shelf around her is filled with unactivated vibranium sand. Around her left wrist, her kimoyo beads glow amber, projecting a volumetric display around her forearm.

She announces to T’Challa, “My prince, we are coming up on them now.” As she disengages from the interface, retracting her hands from the pose, the kimoyo projection shifts and shrinks. (See more detail in the video clip, below.)

The second time we see it is when they pick up Nakia and save the kidnapped girls. On their way back to Wakanda we see Okoye again in the pilot’s seat. No new interactions are seen in this scene though we linger on the shot from behind, with its glowing seatback looking like some high-tech spine.

Now, these brief glimpses don’t give a review a lot to go on. But for a sake of completeness, let’s talk about that volumetric projection around her wrist. I note is that it is a lovely echo of Dr. Strange’s interface for controlling the ~~time stone~~ Eye of Agamatto.

Wrist projections are going to be all the rage at the next Snap, I predict.

But we never really see Okoye look at this VP it or use it. Cross referencing the Wakandan alphabet, those five symbols at the top translate to 1 2 K R I, which doesn’t tell us much. (It doesn’t match the letters seen on the HUD.) It might be a visual do-not-disturb signal to onlookers, but if there’s other meaning that the letters and petals are meant to convey to Okoye, I can’t figure it out. At worst, I think having your wrist movements of one hand emphasized in your peripheral vision with a glowing display is a dangerous distraction from piloting. Her eyes should be on the “road” ahead of her.

The image has been flipped horizontally to illustrate how Okoye would see the display.

Similarly, we never get a good look at the HUD, or see Okoye interact with it, so I’ve got little to offer other than a mild critique that it looks full of pointless ornamental lines, many of which would obscure things in her peripheral vision, which is where humans need the most help detecting things other than motion. But modern sci-fi interfaces generally (and the MCU in particular) are in a baroque period, and this is partly how audiences recognize sci-fi-ness.

I also think that requiring a pilot to maintain full lotus to pilot is a little much, but certainly, if there’s anyone who can handle it, it’s the leader of the Dora Milaje.

One remarkable thing to note is that this is the first brain-input piloting interface in the survey. Okoye thinks what she wants the ship to do, and it does it. I expect, given what we know about kimoyo beads in Wakanda (more on these in a later post), what’s happening is she is sending thoughts to the bracelet, and the beads are conveying the instructions to the ship. As a way to show Okoye’s self-discipline and Wakanda’s incredible technological advancement, this is awesome.

Unfortunately, I don’t have good models for evaluating this interaction. And I have a lot of questions. As with gestural interfaces, how does she avoid a distracted thought from affecting the ship? Why does she not need a tunnel-in-the-sky assist? Is she imagining what the ship should do, or a route, or something more abstract, like her goals? How does the ship grant her its field awareness for a feedback loop? When does the vibranium dashboard get activated? How does it assist her? How does she hand things off to the autopilot? How does she take it back? Since we don’t have good models, and it all happens invisibly, we’ll have to let these questions lie. But that’s part of us, from our less-advanced viewpoint, having to marvel at this highly-advanced culture from the outside.

Black Health Matters

Each post in the Black Panther review is followed by actions that you can take to support black lives.

Thinking back to the terrible loss of Boseman: Fuck cancer. (And not to imply that his death was affected by this, but also:) Fuck the racism that leads to worse medical outcomes for black people.

One thing you can do is to be aware of the diseases that disproportionately affect black people (diabetes, asthma, lung scarring, strokes, high blood pressure, and cancer) and be aware that no small part of these poorer outcomes is racism, systemic and individual. Listen to Dorothy Roberts’ TED talk, calling for an end to race-based medicine.

If you’re the reading sort, check out the books Black Man in a White Coat by Damon Tweedy, or the infuriating history covered in Medical Apartheid by Harriet Washington.

If you are black, in Boseman’s memory, get screened for cancer as often as your doctor recommends it. If you think you cannot afford it and you are in the USA, this CDC website can help you determine your eligibility for free or low-cost screening: https://www.cdc.gov/cancer/nbccedp/screenings.htm. If you live elsewhere, you almost certainly have a better healthcare system than we do, but a quick search should tell you your options.

Cancer treatment is equally successful for all races. Yet black men have a 40% higher cancer death rate than white men and black women have a 20% higher cancer death rate than white women. Your best bet is to detect it early and get therapy started as soon as possible. We can’t always win that fight, but better to try than to find out when it’s too late to intervene. Your health matters. Your life matters.

Trivium Bracelet

12 Feb 2019 by Christopher Noessel

The control token in Las Luchadras is a bracelet that slaps on and instantly renders its wearer an automaton, subject to the remote control.

Here’s something to note about this speculative technology. Orlak could have sold this, just this, to law enforcement around the world and made himself a very rich and powerful person. But the movie makes clear he is a mad engineer, not a mad businessperson, so we have to move on.

From Orlak’s point of view, getting the bracelet on its victim should be very easy. Fortunately, it does just that. Orlak can slap it on in a flick. But it’s also trivially easy for a bystander to remove, which seems like…a design oversight. It should work more like a handcuff, that requires a key to remove. It can’t look like a handcuff, of course, since Orlak wants it to go unnoticed. But in addition to the security, the handcuff function would enable the device to fit wrists of many sizes. As it is, it appears to be tailor-made to an individual.

As the diagram illustrates, not all wrists are made the same, and it would not help Orlak to have to carry around a sizing set when he hasn’t had time to secretly get the victim’s measurements.

From http://oai.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=ADA209600

Lastly, the audience might have benefited from seeing some visual connection between the bracelet and the remote, like a shared material that had an unusual color or glow, but Orlak would not want this connection since it could help someone identify him as the controller.

The Cloak of Levitation, Part 2: Could it ever work?

6 Jul 2017 by Christopher Noessel

How could this work as technology instead of magic?

In the prior post I looked at the Cloak as a bit of wearable technology. Today let’s ask ourselves how possible this is in the real world.

The abilities of the Cloak listed in the first post imply a great deal of functionality: Situational awareness, lightning fast thinking, precision actuators throughout its fabric, gravity controls for itself and its wearer, goal awareness, knowledge of the world. Some of these aren’t going to happen, but some are conceivable over time.

Parts of it are conceivable over time

Some of those abilities make sense with what we know of the arc of technology.

Actuators

Technology keeps shrinking, so a fabric made of strong actuators might be conceivable. I’m not sure muscle wire will ever be this strong, but let’s presume generative design can discover a way to use its relatively weak strength for greater-than-human feats of strength, and that wires can be coordinated when woven into a fabric.

Sensors

The Cloak has complete situational awareness, but where are its sensors? It demonstrates field awareness. We don’t see sensors, but it has to be building this awareness from something. One possibility is that if it was able to connect to sensors around it, much like The Machine and Samaritan Super AIs from Person of Interest or Batman’s cellular panopticon. Alternately, the cape could be dotted with sensors that detect in the x-ray or infrared spectrums, so they can be hidden under the fabric. Let’s say this is pretty futuristic, but possible.

The Cloak’s AI

Yes we have crazy fast processors that seem to keep getting faster, so perhaps the processors could become embeddable in the cloth or perhaps the fibulae. And the amount of cloth in the Cloak is much more than most wearables, so sure, let’s say the computational power can be made this small and sartorial.

Writing this blog takes my vocabulary to some obscure places.

There is the problem of the AI. Some of the Cloak’s abilities imply general, rather than narrow, artificial intelligence. It has complete situation awareness, a clear theory of mind, and seems to learn. We’re not at general AI yet and at least according to Nick Bostrom’s poll, computer scientists are estimating it will be about another decade until we get there, if we can get there at all. Opinions are split as to whether it’s possible, but let’s go optimistic with this one and put it in the conceivable category, with the caveat that it may be wishful thinking.

But some parts break the laws of physics

But then there are a few things that just break the laws of physics, the first of which is flying.

There’s no evidence from other things in the scenes that it is employing a propellant of some kind to do this lifting. It just moves where it wants to. Cloak don’t give a shit. Add the fact that it can hang in place (see the vitrine gif, above) as if it can just ignore the Earth’s gravity, and we’ve got something that earns the Isaac Newton seal of WTF.

It also seems able to pull in any arbitrary direction in space with a great deal of force, as it does when it drags around one of the beefier zealots in a defend-the-master move that would make a Molossus war dog lower its head in respect. Flatworms are the closest thing to a muscled bit of fabric that evolution has come up with, and I don’t think physics would allow it to do this kind of maneuver, either.

Then, when Strange flies wearing it, it doesn’t seem to use its powers to carry him. That would look more like a hammock, or a flying carpet. Instead it somehow grants the power of arbitrary space positioning to him, and then it just gets to relax and ride along and concentrate on looking majestic.

So it can pull in any direction with no anchor, propellant, or regard for gravity; and grant this ability to someone on contact. Sorry, but I think we have to admit that these aspects of the Cloak are just wish fulfillment.

Even if flight could be overlooked, then there comes the question of where’s the power coming from? I don’t see much battery technology trending towards infinite especially when it has to be small enough to be wearable.

So while an engaging vision, we have to be quite careful about drawing design lessons from the Cloak. Enabling technology would be far in the future. And even though personal flight technology (of sorts) exists, but we should take in mind their designs have to deal with the very real issues of thrust and power.

That’s enough for today. In the next post we’ll look at the intelligence and agency evident in the Cloak.
