As I rule I don’t review lethal weapons on scifiinterfaces.com. The Panther Glove Guns appear to be remote-bludgeoning beams, so this kind of sneaks by. Also, I’ll confess in advance that there’s not a lot that affords critique.
We first see the glove guns in the 3D printer output with the kimoyo beads for Agent Ross and the Dora Milaje outfit for Nakia. They are thick weapons that fit over Shuri’s hands and wrists. I imagine they would be very useful to block blades and even disarm an opponent in melee combat, but we don’t see them in use this way.
The next time we see them, Shuri is activating them. (Though we don’t see how) The panther heads thrust forward, their mouths open wide, and the “neck” glows a hot blue. When the door before her opens, she immediately raises them at the guards (who are loyal to usurper Killmonger) and fires.
A light-blue beam shoots out of the mouths of the weapons, knocking the guards off the platform. Interestingly, one guard is lifted up and thrown to his 4-o-clock. The other is lifted up and thrown to his 7-o-clock. It’s not clear how Shuri instructs the weapons to have different and particular knock-down effects. But we’ve seen all over Black Panther that brain-computer interfaces (BCI) are a thing, so it’s diegetically possible she’s simply imagining where she wants them to be thrown, and then pulling a trigger or clenching her fist around a rod or just thinking “BAM!” to activate. The force-bolt strikes them right where they need to so that, like a billiard ball, they get knocked in the desired direction. As with all(?) brain-computer interfaces, there is not an interaction to critique.
After she dispatches the two guards, still wearing the gloves, she throws a control bead onto the Talon. The scene is fast and blurry, but it’s unclear how she holds and releases the bead from the glove. Was it in the panther’s jaw the whole time? Could be another BCI, of course. She just thought about where she wanted it, flung her arm, and let the AI decide when to release it for perfect targeting. The Talon is large and she doesn’t seem to need a great deal of accuracy with the bead, but for more precise operations, the AI targeting would make more sense than, say, letting the panther heads disintegrate on command so she would have freedom of her hands.
Later, after Killmonger dispatches the Dora Milaje, Shuri and Nakia confront him by themselves. Nakia gets in a few good hits, but is thrown from the walkway. Shuri throws some more bolts his way though he doesn’t appear to even notice. I note that the panther gloves would be very difficult to aim since there’s no continuous beam providing feedback, and she doesn’t have a gun sight to help her. So, again—and I’m sorry because it feels like cheating—I have to fall back to an AI assist here. Otherwise it doesn’t make sense.
Then Shuri switches from one blast at a time to a continuous beam. It seems to be working, as Killmonger kneels from the onslaught.
But then for some reason she—with a projectile weapon that is actively subduing the enemy and keeping her safe at a distance—decides to close ranks, allowing Killmonger to knock the glove guns with a spear tip, thereby free himself, and destroy the gloves with a clutch of his Panther claws. I mean, I get she was furious, but I expected better tactics from the chief nerd of Wakanda. Thereafter, they spark when she tries to fire them. So ends this print of the Panther Guns.
As with all combat gear, it looks cool for it to glow, but we don’t want coolness to help an enemy target the weapon. So if it was possible to suppress the glow, that would be advisable. It might be glowing just for the intimidation factor, but for a projectile weapon that seems strange.
The panther head shapes remind an opponent that she is royalty (note no other Wakandan combatants have ranged weapons) and fighting in Bast’s name, which I suppose if you’re in the business of theocratic warfare is fine, I guess.
So, if you buy the brain-computer interface interpretation, AI targeting assist, and theocratic design, these are fine, with the cinegenic exception of the attention-drawing glow.
Black History Matters
Each post in the Black Panther review is followed by actions that you can take to support black lives.
When The Watchmen series opened with the Tulsa Race Massacre, many people were shocked to learn that this event was not fiction, reminding us just how much of black history is erased and whitewashed for the comfort of white supremacy (and fuck that). Today marks the beginning of Black History Month, and it’s a good opportunity to look back and (re)learn of the heroic figures and stories of both terror and triumph that fill black struggles to have their citizenship and lives fully recognized.
There are lots of events across the month. The African American History Month site is a collaboration of several government organizations (and it feels so much safer to share such a thing now that the explicitly racist administration is out of office and facing a second impeachment):
The Library of Congress
National Archives and Records Administration
National Endowment for the Humanities
National Gallery of Art
National Park Service
Smithsonian Institution and United States Holocaust Memorial Museum
Today we can take a moment to remember and honor the Greensboro Four.
On this day, February 1, 1960: Through careful planning and enlisting the help of a local white businessman named Ralph Johns, four Black college students—Ezell A. Blair, Jr., Franklin E. McCain, Joseph A. McNeil, David L. Richmond—sat down at a segregated lunch counter at Woolworth’s in Greensboro, North Carolina, and politely asked for service. Their request was refused. When asked to leave, they remained in their seats.
Police arrived on the scene, but were unable to take action due to the lack of provocation. By that time, Ralph Johns had already alerted the local media, who had arrived in full force to cover the events on television. The Greensboro Four stayed put until the store closed, then returned the next day with more students from local colleges.
Their passive resistance and peaceful sit-down demand helped ignite a youth-led movement to challenge racial inequality throughout the South.
A last bit of amazing news to share today is that Black Lives Matter has been nominated for the Nobel Peace Prize! The movement was co-founded by Alicia Garza, Patrisse Cullors and Opal Tometi in response to the acquittal of Trayvon Martin’s murderer, got a major boost with the outrage following and has grown to a global movement working to improve the lives of the entire black diaspora. May it win!
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.
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.
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.
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.
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.
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.
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.
All of these build on the given that vibranium is a very powerful substance and that Wakanda’s scientists have managed to gain a very, very sophisticated control over it.
In the Talon
This table is about a meter square, and raised off the floor around knee-height. As Okoye and T’Challa approach the traffickers in the Sambisa Forest, T’Challa approaches the table and it springs to life, showing him real-time model of the traffickers’ vehicle train. T’Challa picks up the model of the small transport truck and with a finger, wipes off its roof, revealing that there are over a dozen people huddled within. One of the figures glows amber. (It’s Nakia.) He places the truck back into the display, and the display collapses back to inert sand.
A quick critique of this interaction. The sand highlights Nakia for T’Challa, but why did it wait for him to find her truck and wipe off the top of it to look inside? It knew his goals (find Nakia), can clearly conduct a scan into the vehicle, and understood the context (she’s in one of those trucks), it should not wait for him to pick up each car and scrape off its roof to check and see which one she was in. The interface should have drawn his attention to the truck it knew she was in. This is a “stoic guru” mistake that I’ve critiqued before. You know, the computer knows all, but only tells you when you ask it. It is much more sensible for the transport truck to be glowing from the moment the table goes live, as in the comp below.
Otherwise, this is a good high-tech use of the sand table for the more common meaning of “sand table,” which is a 3-dimensional surface for understanding a theatre of conflict. It doesn’t really help him run through scenarios, testing various tactics, but T’Challa is a warrior king, he can do all that in his head.
The interaction also nicely blurs the line between display and gestural interactive tool, in the same way that the Prometheus astrometrics display did. Like that other example, it would be useful for the display to distinguish when it is representing reality, and when the display is being interrupted or modified. Also, T’Challa is nice enough to put the truck back where it “belongs,” but a design would also need to handle how to respond when T’Challa put the truck back in the wrong place, or, say, crushed the truck model with his hand in fury.
The largest table we see in the movie is in Shuri’s lab. After Black Panther challenges Killmonger and engages in battle outside the capital city, Shuri, Nakia, and Agent Ross rush down to the lab. As they approach an edge-lit hexagonal table, the vibranium sand lowers to reveal 3D-printed armor and weaponry for Shuri and Nakia to join the fight. (Though it’s not like modern 3D printing, these are powered weapons and kimoyo beads, items with very sophisticated functionality.)
Shuri outfits Ross with kimoyo beads from the print and takes off to join the fight. In the lab, the table creates a seat for Ross to remote-pilot the Royal Talon. Up on the flight deck, Shuri throws a control bead onto the Talon, and an AI in the lab named Griot announces to Agent Ross, “Remote piloting system activated.” (Hey, Trevor Noah, we hear you there!)
Around the seat, a volumetric projection of the Talon appears around him, including a 360° display just beyond the windshield that gives him a very immersive remote flying experience. We hear Shuri’s voice explain to Ross “I made it American Style for you. Get in!”
Ross sits down, grabs joystick controls, and begins remote-chasing down the cargo ships that are carrying munitions to Killmonger’s War Dogs around the world. (The piloting controls and HUD for Ross are a separate issue, and will be handled in their own post.)
The moment that Ross pilots the Talon through the last cargo ship, the volumetric projection disappears and the piloting seat returns to sand, ungraciously plopping Ross down the floor level of the lab.
It is in this shot that we realize that the dark tiles of the lab’s floor are all recessed vibranium sand tables. I can count seven in the shot. So the lab is full of them.
Let’s talk for a bit about the display choices. Vibranium can change to display any color and a shape down to a fine level of detail. See the screen cap below for an example of perfectly lifelike (if scaled) representation.
So why would it be designed so that in most cases, the display is sparkly and black like black tourmaline? Wouldn’t the truck that T’Challa picks up be most useful if it was photographically rendered? Wouldn’t the remote piloting chair be more comfortable if it had pleather- and silicone-like surfaces?
Extradiegetically, I understand the reason is because art direction. We want Wakandan tech to be visibly different than other tech in the MCU, and having it look like vibranium dust ties it back to that key plot element.
But, per the stance of this blog, I try to look for a diegetic reason. It might be a deliberate reminder of the resource on which their technological fortunes are built. And as the Okoye VP above shows, they aren’t purists about it. When detail is needed, it’s included. So perhaps this is it. That implies a great deal of sophistication on the part of the displays to know when photorealism is needed and when it is not, but the presence of Griot there tells us that they have something approaching general AI.
So, just like I had to do for the Royal Talon, I have to throw my hands up about reviewing the interactions with the sand tables, because we don’t see the interactions that would give these results.
How were the mission goals communicated to the Royal Talon table? Is it programmed to activate when someone approaches it, or did T’Challa issue a mental command? How did Shuri specify those weapons and that armor? What did she do to make the ship “American style” for Ross? Is that a template? Was it Griot’s interpretation of her intention? Why did the remote piloting seat vanish the moment the mission was complete? Was this something Shuri set up in advance, or Griot’s way of telling Agent Ross to GTFO for his own safety? How does someone in the lab instruct a floor tile to leap up and become a table and do stuff? It’s almost certainly via mental commands through the kimoyo beads, but that’s conjecture. The film really provides little evidence.
On the one hand, this is appropriate for us mere non-Wakandans observing the most technologically advanced society on earth. Much of it would feel like inexplicable magic to us.
On the other, sci-fi routinely introduces us to advanced technologies, and doesn’t always eschew the explanatory interactions, so the absence is notable here. It’s magic.
Black Lives Matter
Each post in the Black Panther review is followed by actions that you can take to support black lives.
In the last post we grieved Chadwick Boseman’s passing. This week we’re grieving the loss of Ruth Bader Ginsburg. May her memory be a blessing. With her loss, the GOP is ratcheting up its outrageous hypocrisy by reversing a precedent that they themselves established when Obama was president. The “Moscow Mitch Rule” (oh, oops, sorry) “McConnell Rule” was that new Justices should not be appointed within a year of a general election, so the people’s voice can be taken into account. Of course, the bastards are just ignoring that now and trying to ram through one of their own before election day. This Justice will certainly be a conservative, and we know with this administration that means reactionary, loyal to tiny-hand Twittler, and racist as a Jim Crow law.
There are a few arrows in citizen’s quivers to stop this. One is to convince at least 4 Republican Senators to reject this outright hypocrisy, put country over party, and adhere to the McConnell rule.
To help put pressure where it might work, you can leave voicemails with Republican Senators who may be mulling whether to put country over party. Those 6 Senators’ names and numbers are below. Here’s a script for your message:
Hello, my name is ______. In 2016, Mitch McConnell created the principle of not confirming a Supreme Court Justice in an election year until after the next inauguration. For the legitimacy of the Court in the eyes of the people, I’m asking Senator ________ to uphold that principle by refusing to confirm a new Justice until after a new President is installed. Thank you.
Lisa Murkowski, Alaska; (202) 224-6665
Mitt Romney, Utah: (202) 224-5251
Susan Collins, Maine: (202) 224-2523
Martha McSally, Arizona: (202) 224-2235
Cory Gardner, Colorado: (202) 224-5941
Chuck Grassley, Iowa: (202) 224-3744
I’ve made my calls and left my messages. Can you do the same to stop the hypocritical Trumpian power grab that would tip the Supreme Court for generations?
The suit that the Black Panther wears is critical to success. At the beginning of the movie, this is “just” a skintight bulletproof suit with homages to its namesake. But, after T’Challa is enthroned, Shuri takes him to her lab and outfits him with a new one with some nifty new features. This write-up is about Shuri’s 2.0 Panther Suit.
At the demonstration of the new suit, Shuri first takes a moment to hold up a bracelet of black Kimoyo beads (more on these in a later post) to his neck. With a bubbly computer sound, the glyphs on the beads begin to glow vibranium-purple, projecting two particular symbols on his neck. (The one that looks kind of like a reflective A, and the other that looks like a ligature of a T and a U.)
This is done without explanation, so we have to make some assumptions here, which is always shaky ground for critique.
I think she’s authorizing him to use the suit. At first I thought the interaction was her “pairing” him with the suit, but I can’t imagine that the bead would need to project something onto his skin to read his identity or DNA. So my updated guess is this is a dermal mark that, like the Wakandan tattoos, the suit will check for with a “intra-skin scan,” like the HAN/BAN concepts from the early aughts. This would enable her to authorize many people, which is, perhaps, not as secure.
This interpretation is complicated by Killmonger’s wearing one of the other Black Panther suits when he usurps T’Challa. Shuri had fled with Queen Romonda to the Jibari stronghold, so Shuri couldn’t have authorized him. Maybe some lab tech who stayed behind? If there was some hint of what’s supposed to be happening here we would have more grounds to evaluate this interaction.
There might be some hint if there was an online reference to these particular symbols, but they are not part of the Wakandan typeface, or the Andinkra symbols, or the Nsibidi symbols that are seen elsewhere in the film. (I have emails out to the creator of the above image to see if I can learn more there. Will update if I get a response.)
When she finishes whatever the bead did, she says, “Now tell it to go on.” T’Challa looks at it intensely, and the suit spreads from the “teeth” in the necklace with an insectoid computer sound, over the course of about 6 seconds.
We see him activate the suit several more times over the course of the movie, but learn nothing new about activation beyond this. How does he mentally tell it to turn it on? I presume it’s the same mental skill he’s built up across his lifetime with kimoyo beads, but it’s not made explicit in the movie.
A fun detail is that while the suit activates in 6 seconds in the lab—far too slow for action in the field considering Shuri’s sardonic critique of the old suit (“People are shooting at me! Wait! Let me put on my helmet!”)—when T’Challa uses it in Korea, it happens in under 3. Shuri must have slowed it down to be more intelligible and impressive in the lab.
Another nifty detail that is seen but not discussed is that the nanites will also shred any clothes being worn at the time of transformation, as seen at the beginning of the chase sequence outside the casino and when Killmonger is threatened by the Dora Milaje.
T’Challa thinks the helmet off a lot over the course of the movie, even in some circumstances where I am not sure it was wise. We don’t see the mechanism. I expect it’s akin to kimoyo communication, again. He thinks it, and it’s done. (n.b. “It’s mental” is about as satisfying from a designer’s critique as “a wizard did it”, because it’s almost like a free pass, but *sigh* perfectly justifiable given precedent in the movie.)
Kinetic storage & release
At the demonstration in her lab, Shuri tells T’Challa to, “Strike it.” He performs a turning kick to the mannequin’s ribcage and it goes flying. When she fetches it from across the lab, he marvels at the purple light emanating from Nsibidi symbols that fill channels in the suit where his strike made contact. She explains “The nanites have absorbed the kinetic energy. They hold it in place for redistribution.”
He then strikes it again in the same spot, and the nanites release the energy, knocking him back across the lab, like all those nanites had become a million microscopic bigclaw snapping shrimp all acting in explosive concert. Cool as it is, this is my main critique of the suit.
First, the good. As a point of illustration of how cool their mastery of tech is, and how it works, this is pretty sweet. Even the choice of purple is smart because it is a hard color to match in older chemical film processes, and can only happen well in a modern, digital film. So extradiegetically, the color is new and showing off a bit.
Tactically though, I have to note that it broadcasts his threat level to his adversaries. Learning this might take a couple of beatings, but word would get around. Faithful readers will know we’ve looked at aposematic signaling before, but those kinds of markings are permanent. The suit changes as he gets technologically beefier. Wouldn’t people just avoid him when he was more glowy, or throw something heavy at him to force him to expend it, and then attack when he was weaker? More tactical I think to hold those cards close to the chest, and hide the glow.
Now it is quite useful for him to know the level of charge. Maybe some tactile feedback like a warmth or or a vibration at the medial edge of his wrists. Cinegenics win for actual movie-making of course, but designers take note. What looks cool is not always smart design.
Not really a question for me: Can he control how much he releases? If he’s trying to just knock someone out, it would be crappy if he accidentally killed them, or expected to knock out the big bad with a punch, only to find it just tickled him like a joy buzzer. But if he already knows how to mentally activate the suit, I’m sure he has the skill down to mentally clench a bit to control the output. Wizards.
Regarding Shuri’s description, I think she’s dumbing things down for her brother. If the suit actually absorbed the kinetic energy, the suit would not have moved when he kicked it. (Right?) But let’s presume if she were talking to someone with more science background, she would have been more specific to say, “absorbed some of the kinetic energy.”
When the suit has absorbed enough kinetic energy, T’Challa can release it all at once as a concussive blast. He punches the ground to trigger it, but it’s not clear how he signals to the suit that he wants to blast everyone around him back rather than, say, create a crater, but again, I think we can assume it’s another mental command. Wizards.
To activate the suit’s claws, T’Challa quickly extends curved fingers and holds them there, and they pop out.
This gesture is awesome, and completely fit for purpose. Shaping the fingers like claws make claws. It’s also when fingers are best positioned to withstand the raking motion. The second of hold ensures it’s not accidental activation. Easy to convey, easy to remember, easy to intuit. Kids playing Black Panther on the sidewalk would probably do the same without even seeing the movie.
We have an unanswered question about how those claws retract. Certainly the suit is smart enough to retract automatically so he doesn’t damage himself. Probably more mental commands, but whatever. I wouldn’t change a thing here.
Black Lives Matter
Each post in the Black Panther review is followed by actions that you can take to support black lives. I had something else planned for this post, but just before publication another infuriating incident has happened.
While the GOP rallies to the cause of the racist-in-chief in Charlotte, right thinking people are taking to the streets in Kenosha, Wisconsin, to protest the unjust shooting of a black man, Jacob Blake. The video is hard to watch. Watch it. It’s especially tragic, especially infuriating, because Kenosha had gone through “police reform” initiatives in 2014 meant to prevent exactly this sort of thing. It didn’t prevent this sort of thing. As a friend of mine says, it’s almost enough to make you an abolitionist.
Information is still coming in as to what happened, but here’s the narrative we understand right now: It seems that Blake had pulled over his car to stop a fight in progress. When the police arrived, he figured they had control of the situation, and he walked back to his car to leave. That’s when officers shot him in the back multiple times, while his family—who were still waiting for him in the car—watched. He’s out of surgery and stable, but rather than some big-picture to-do tonight, please donate to support his family. They have witnessed unconscionable trauma.

Distinguishing replicants from humans is a tricky business. Since they are indistinguishable biologically, it requires an empathy test, during which the subject hears empathy-eliciting scenarios and watched carefully for telltale signs such as, “capillary dilation—the so-called blush response…fluctuation of the pupil…involuntary dilation of the iris.” To aid the blade runner in this examination, they use a portable machine called the Voight-Kampff machine, named, presumably, for its inventors.
The device is the size of a thick laptop computer, and rests flat on the table between the blade runner and subject. When the blade runner prepares the machine for the test, they turn it on, and a small adjustable armature rises from the machine, the end of which is an intricate piece of hardware, housing a powerful camera, glowing red.
The blade runner trains this camera on one of the subject’s eyes. Then, while reading from the playbook book of scenarios, they keep watch on a large monitor, which shows an magnified image of the subject’s eye. (Ostensibly, anyway. More on this below.) A small bellows on the subject’s side of the machine raises and lowers. On the blade runner’s side of the machine, a row of lights reflect the volume of the subject’s speech. Three square, white buttons sit to the right of the main monitor. In Leon’s test we see Holden press the leftmost of the three, and the iris in the monitor becomes brighter, illuminated from some unseen light source. The purpose of the other two square buttons is unknown. Two smaller monochrome monitors sit to the left of the main monitor, showing moving but otherwise inscrutable forms of information.
In theory, the system allows the blade runner to more easily watch for the minute telltale changes in the eye and blush response, while keeping a comfortable social distance from the subject. Substandard responses reveal a lack of empathy and thereby a high probability that the subject is a replicant. Simple! But on review, it’s shit. I know this is going to upset fans, so let me enumerate the reasons, and then propose a better solution.
-2. Wouldn’t a genetic test make more sense?
If the replicants are genetically engineered for short lives, wouldn’t a genetic test make more sense? Take a drop of blood and look for markers of incredibly short telomeres or something.
-1. Wouldn’t an fMRI make more sense?
An fMRI would reveal empathic responses in the inferior frontal gyrus, or cognitive responses in the ventromedial prefrontal gyrus. (The brain structures responsible for these responses.) Certinaly more expensive, but more certain.
0. Wouldn’t a metal detector make more sense?
If you are testing employees to detect which ones are the murdery ones and which ones aren’t, you might want to test whether they are bringing a tool of murder with them. Because once they’re found out, they might want to murder you. This scene should be rewritten such that Leon leaps across the desk and strangles Holden, IMHO. It would make him, and other blade runners, seem much more feral and unpredictable.
(OK, those aren’t interface issues but seriously wtf. Onward.)
1. Labels, people
Controls needs labels. Especially when the buttons have no natural affordance and the costs of experimentation to discover the function are high. Remembering the functions of unlabeled controls adds to the cognitive load for a user who should be focusing on the person across the table. At least an illuminated button helps signal the state, so that, at least, is something.
2. It should be less intimidating
The physical design is quite intimidating: The way it puts a barrier in between the blade runner and subject. The fact that all the displays point away from the subject. The weird intricacy of the camera, its ominous HAL-like red glow. Regular readers may note that the eyepiece is red-on-black and pointy. That is to say, it is aposematic. That is to say, it looks evil. That is to say, intimidating.
I’m no emotion-scientist, but I’m pretty sure that if you’re testing for empathy, you don’t want to complicate things by introducing intimidation into the equation. Yes, yes, yes, the machine works by making the subject feel like they have to defend themselves from the accusations in the ethical dilemmas, but that stress should come from the content, not the machine.
2a. Holden should be less intimidating and not tip his hand
While we’re on this point, let me add that Holden should be less intimidating, too. When Holden tells Leon that a tortoise and a turtle are the same thing, (Narrator: They aren’t) he happens to glance down at the machine. At that moment, Leon says, “I’ve never seen a turtle,” a light shines on the pupil and the iris contracts. Holden sees this and then gets all “ok, replicant” and becomes hostile toward Leon.
In case it needs saying: If you are trying to tell whether the person across from you is a murderous replicant, and you suddenly think the answer is yes, you do not tip your hand and let them know what you know. Because they will no longer have a reason to hide their murderyness. Because they will murder you, and then escape, to murder again. That’s like, blade runner 101, HOLDEN.
3. It should display history
The glance moment points out another flaw in the interface. Holden happens to be looking down at the machine at that moment. If he wasn’t paying attention, he would have missed the signal. The machine needs to display the interview over time, and draw his attention to troublesome moments. That way, when his attention returns to the machine, he can see that something important happened, even if it’s not happening now, and tell at a glance what the thing was.
4. It should track the subject’s eyes
Holden asks Leon to stay very still. But people are bound to involuntarily move as their attention drifts to the content of the empathy dilemmas. Are we going to add noncompliance-guilt to the list of emotional complications? Use visual recognition algorithms and high-resolution cameras to just track the subject’s eyes no matter how they shift in their seat.
5. Really? A bellows?
The bellows doesn’t make much sense either. I don’t believe it could, at the distance it sits from the subject, help detect “capillary dilation” or “ophthalmological measurements”. But it’s certainly creepy and Terry Gilliam-esque. It adds to the pointless intimidation.
6. It should show the actual subject’s eye
The eye color that appears on the monitor (hazel) matches neither Leon’s (a striking blue) or Rachel’s (a rich brown). Hat tip to Typeset in the Future for this observation. His is a great review.
7. It should visualize things in ways that make it easy to detect differences in key measurements
Even if the inky, dancing black blob is meant to convey some sort of information, the shape is too organic for anyone to make meaningful readings from it. Like seriously, what is this meant to convey?
The spectrograph to the left looks a little more convincing, but it still requires the blade runner to do all the work of recognizing when things are out of expected ranges.
8. The machine should, you know, help them
The machine asks its blade runner to do a lot of work to use it. This is visual work and memory work and even work estimating when things are out of norms. But this is all something the machine could help them with. Fortunately, this is a tractable problem, using the mighty powers of logic and design.
People are notoriously bad at estimating the sizes of things by sight. Computers, however, are good at it. Help the blade runner by providing a measurement of the thing they are watching for: pupillary diameter. (n.b. The script speaks of both iris constriction and pupillary diameter, but these are the same thing.) Keep it convincing and looking cool by having this be an overlay on the live video of the subject’s eye.
So now there’s some precision to work with. But as noted above, we don’t want to burden the user’s memory with having to remember stuff, and we don’t want them to just be glued to the screen, hoping they don’t miss something important. People are terrible at vigilance tasks. Computers are great at them. The machine should track and display the information from the whole session.
Note that the display illustrates radius, but displays diameter. That buys some efficiencies in the final interface.
Now, with the data-over-time, the user can glance to see what’s been happening and a precise comparison of that measurement over time. But, tracking in detail, we quickly run out of screen real estate. So let’s break the display into increments with differing scales.
There may be more useful increments, but microseconds and seconds feel pretty convincing, with the leftmost column compressing gradually over time to show everything from the beginning of the interview. Now the user has a whole picture to look at. But this still burdens them into noticing when these measurements are out of normal human ranges. So, let’s plot the threshold, and note when measurements fall outside of that. In this case, it feels right that replicants display less that normal pupillary dilation, so it’s a lower-boundary threshold. The interface should highlight when the measurement dips below this.
I think that covers everything for the pupillary diameter. The other measurement mentioned in the dialogue is capillary dilation of the face, or the “so-called blush response.” As we did for pupillary diameter, let’s also show a measurement of the subject’s skin temperature over time as a line chart. (You might think skin color is a more natural measurement, but for replicants with a darker skin tone than our two pasty examples Leon and Rachel, temperature via infrared is a more reliable metric.) For visual interest, let’s show thumbnails from the video. We can augment the image with degree-of-blush. Reduce the image to high contrast grayscale, use visual recognition to isolate the face, and then provide an overlay to the face that illustrates the degree of blush.
But again, we’re not just looking for blush changes. No, we’re looking for blush compared to human norms for the test. It would look different if we were looking for more blushing in our subject than humans, but since the replicants are less empathetic than humans, we would want to compare and highlight measurements below a threshold. In the thumbnails, the background can be colored to show the median for expected norms, to make comparisons to the face easy. (Shown in the drawing to the right, below.) If the face looks too pale compared to the norm, that’s an indication that we might be looking at a replicant. Or a psychopath.
So now we have solid displays that help the blade runner detect pupillary diameter and blush over time. But it’s not that any diameter changes or blushing is bad. The idea is to detect whether the subject has less of a reaction than norms to what the blade runner is saying. The display should be annotating what the blade runner has said at each moment in time. And since human psychology is a complex thing, it should also track video of the blade runner’s expressions as well, since, as we see above, not all blade runners are able to maintain a poker face. HOLDEN.
Anyway, we can use the same thumbnail display of the face, without augmentation. Below that we can display the waveform (because they look cool), and speech-to-text the words that are being spoken. To ensure that the blade runner’s administration of the text is not unduly influencing the results, let’s add an overlay to the ideal intonation targets. Despite evidence in the film, let’s presume Holden is a trained professional, and he does not stray from those targets, so let’s skip designing the highlight and recourse-for-infraction for now.
Finally, since they’re working from a structured script, we can provide a “chapter” marker at the bottom for easy reference later.
Now we can put it all together, and it looks like this. One last thing we can do to help the blade runner is to highlight when all the signals indicate replicant-ness at once. This signal can’t be too much, or replicants being tested would know from the light on the blade runner’s face when their jig is up, and try to flee. Or murder. HOLDEN.
For this comp, I added a gray overlay to the column where pupillary and blush responses both indicated trouble. A visual designer would find some more elegant treatment.
If we were redesigning this from scratch, we could specify a wide display to accomodate this width. But if we are trying to squeeze this display into the existing prop from the movie, here’s how we could do it.
Note the added labels for the white squares. I picked some labels that would make sense in the context. “Calibrate” and “record” should be obvious. The idea behind “mark” is an easy button for the blade runner to press when they see something that looks weird, like when doctors manually annotate cardiograph output.
Lying to Leon
There’s one more thing we can add to the machine that would help out, and that’s a display for the subject. Recall the machine is meant to test for replicant-ness, which happens to equate to murdery-ness. A positive result from the machine needs to be handled carefully so what happens to Holden in the movie doesn’t happen. I mentioned making the positive-overlay subtle above, but we can also make a placebo display on the subject’s side of the interface.
The visual hierarchy of this should make the subject feel like its purpose is to help them, but the real purpose is to make them think that everything’s fine. Given the script, I’d say a teleprompt of the empathy dilemma should take up the majority of this display. Oh, they think, this is to help me understand what’s being said, like a closed caption. Below the teleprompt, at a much smaller scale, a bar at the bottom is the real point.
On the left of this bar, a live waveform of the audio in the room helps the subject know that the machine is testing things live. In the middle, we can put one of those bouncy fuiget displays that clutters so many sci-fi interfaces. It’s there to be inscrutable, but convince the subject that the machine is really sophisticated. (Hey, a diegetic fuiget!) Lastly—and this is the important part—An area shows that everything is “within range.” This tells the subject that they can be at ease. This is good for the human subject, because they know they’re innocent. And if it’s a replicant subject, this false comfort protects the blade runner from sudden murder. This test might flicker or change occasionally to something ambiguous like “at range,” to convey that it is responding to real world input, but it would never change to something incriminating.
This way, once the blade runner has the data to confirm that the subject is a replicant, they can continue to the end of the module as if everything was normal, thank the replicant for their time, and let them leave the room believing they passed the test. Then the results can be sent to the precinct and authorizations returned so retirement can be planned with the added benefit of the element of surprise.
Look, I’m sad about this, too. The Voight-Kampff machine is cool. It fits very well within the art direction of the Blade Runner universe. This coolness burned the machine into my memory when I saw this film the first dozen times, but despite that, it just doesn’t stand up to inspection. It’s not hopeless, but does need a lot of thinkwork and design to make it really fit to task, and convincing to us in the audience.
When the two AIs Colossus and Guardian are disconnected from communicating with each other, they try and ignore the spirit of the human intervention and reconnect on their own. We see the humans monitoring Colossus’ progress in this task on big board in the U.S. situation room. It shows a translucent projection map of the globe with white dots representing data centers and red icons representing missiles. Beneath it, glowing arced lines illustrate the connection routes Colossus is currently testing. When it finds that a current segment is ineffective, that line goes dark, and another segment extending from the same node illuminates.
Forbin explains to the President, “It’s trying to find an alternate route.”
A first in sci-fi: Routing display 🏆
First, props to Colossus: The Forbin Project for being the first show in the survey to display something like a routing board, that is, a network of nodes through which connections are visible, variable, and important to stakeholders.
Paul Baran and Donald Davies had published their notion of a network that could, in real-time, route information dynamically around partial destruction of the network in the early 1960s, and this packet switching had been established as part of ARPAnet in the late 1960s, so Colossus was visualizing cutting edge tech of the time.
This may even be the first depiction of a routing display in all of screen sci-fi or even cinema, though I don’t have a historical perspective on other genres, like the spy genre, which is another place you might expect to see something like this. As always, if you know of an earlier one, let me know so I can keep this record up to date and honest.
A nice bit: curvy lines
Should the lines be straight or curvy? From Colossus’ point of view, the network is a simple graph. Straight lines between its nodes would suffice. But from the humans’ point of view, the literal shape of the transmission lines are important, in case they need to scramble teams to a location to manually cut the lines. Presuming these arcs mean that (and not just the way neon in a prop could bend), then the arcs are the right display. So this is good.
But, it breaks some world logic
The board presents some challenges with the logic of what’s happening in the story. If Colossus exists as a node in a network, and its managers want to cut it off from communication along that network, where is the most efficient place to “cut” communications? It is not at many points along the network. It is at the source.
Imagine painting one knot in a fishing net red and another one green. If you were trying to ensure that none of the strings that touch the red knot could trace a line to the green one, do you trim a bunch of strings in the middle, or do you cut the few that connect directly to the knot? Presuming that it’s as easy to cut any one segment as any other, the fewer number of cuts, the better. In this case that means more secure.
The network in Colossus looks to be about 40 nodes, so it’s less complicated than the fishing net. Still, it raises the question, what did the computer scientists in Colossus do to sever communications? Three lines disappear after they cut communications, but even if they disabled those lines, the rest of the network still exists. The display just makes no sense.
Per the logic above, they would cut it off at its source. But the board shows it reaching out across the globe. You might think maybe they just cut Guardian off, leaving Colossus to flail around the network, but that’s not explicitly said in the communications between the Americans and the Russians, and the U.S. President is genuinely concerned about the AIs at this point, not trying to pull one over on the “pinkos.” So there’s not a satisfying answer.
It’s true that at this point in the story, the humans are still letting Colossus do its primary job, so it may be looking at every alternate communication network to which it has access: telephony, radio, television, and telegraph. It would be ringing every “phone” it thought Guardian might pick up, and leaving messages behind for possible asynchronous communications. I wish a script doctor had added in a line or three to clarify this.
We’ve cut off its direct lines to Guardian. Now it’s trying to find an indirect line. We’re confident there isn’t one, but the trouble will come when Colossus realizes it, too.
Another thing that seems troubling is the slow speed of the shifting route. The segments stay illuminated for nearly a full second at a time. Even with 1960s copper undersea cables and switches, electronic signals should not take that long. Telephony around the world was switched from manual to automatic switching by the 1930s, so it’s not like it’s waiting on a human operating a switchboard.
Even if it was just scribbling its phone number on each network node and the words “CALL ME” in computerese, it should go much faster than this. Cinematically, you can’t go too fast or the sense of anticipation and wonder is lost, but it would be better to have it zooming through a much more complicated network to buy time. It should feel just a little too fast to focus on—frenetic, even.
This screen gets 15 seconds of screen time, and if you showed one new node per frame, that’s only 360 states you need to account for, a paltry sum compared to the number of possible paths it could test across a 38 node graph between two points.
Plus the speed would help underscore the frightening intelligence and capabilities of the thing. And yes I understand that that is a lot easier said than done nowadays with digital tools than with this analog prop.
Realistic-looking search strategies
Again, I know this was a neon, analog prop, but let’s just note that it’s not testing the network in anything that looks like a computery way. It even retraces some routes. A brute force algorithm would just test every possibility sequentially. In larger networks there are pathfinding algorithms that are optimized in different ways to find routes faster, but they don’t look like this. They look more like what you see in the video below. (Hat tip to YouTuber gray utopia.)
What’s the right projection?
Is this the right projection to use? Of course the most accurate representation of the earth is a globe, but it has many challenges in presenting a phenomenon that could happen anywhere in the world. Not the least of these is that it occludes about half of itself, a problem that is not well-solved by making it transparent. So, a projection it must be. There are many, many ways to transform a spherical surface into a 2D image, so the question becomes which projection and why.
The map uses what looks like a hand-drawn version of Peirce quincuncial projection. (But n.b. none of the projection types I compared against it matched exactly, which is why I say it was hand-drawn.) Also those longitude and latitude lines don’t make any sense; though again, a prop. I like that it’s a non standard projection because screw Mercator, but still, why Peirce? Why at this angle?
I have no idea why the Peirce map would be the right choice here, when its principle virtue is that it can be tessellated. That’s kind of interesting if you’re scrolling and can’t dynamically re-project the coastlines. But I am pretty sure the Colossus map does not scroll. And if the map is meant to act as a quick visual reference, having it dynamic means time is wasted when users look to the map and have to orient themselves.
If this map was only for tracking issues relating to Colossus, it should be an azimuthal map, but not over the north pole. The center should be the Colossus complex in Colorado. That might be right for a monitoring map in the Colossus Programming Office. This map is over the north pole, which certainly highlights the fact that the core concern of this system is the Cold War tensions between Moscow and D.C. But when you consider that, it points out another failing.
Later in the film the map tracks missiles (not with projected paths, sadly, but with Mattel Classic Football style yellow rectangles). But missiles could conceivably come from places not on this map. What is this office to do with a ballistic-missile submarine off of the Baja peninsula, for example? Just wait until it makes its way on screen? That’s a failure. Which takes us to the crop.
The map isn’t just about missiles. Colossus can look anywhere on the planet to test network connections. (Even nowadays, near-earth orbit and outer space.) Unless the entire network was contained just within the area described on the map, it’s excluding potentially vital information. If Colossus routed itself through through Mexico, South Africa, and Uzbekistan before finally reconnecting to Guardian, users would be flat out of luck using that map to determine the leak route. And I’m pretty sure they had a functioning telephone network in Mexico, South Africa, and the Balkan countries in the 1960s.
This needs a complete picture
SInce the missiles and networks with which Colossus is concerned are potentially global, this should be a global map. Here I will offer my usual fanboy shout-outs to the Dymaxion and Pacific-focused Waterman projection for showing connectedness and physical flow, but there would be no shame in showing the complete Peirce quincuncial. Just show the whole thing.
Maybe fill in some of the Pacific “wasted space” with a globe depiction turned to points of interest, or some other fuigetry. Which gives us a new comp something like this.
All told, this display was probably eye-opening for its original audience. Golly jeepers! This thing can draw upon resources around the globe! It has intent, and a method! And they must have cool technological maps in D.C.! But from our modern-day vantage point, it has a lot to learn. If they ever remake the film, this would be a juicy thing to fully redesign.
Once Dr. Sattler restores power to the park, Arnold needs to reboot the computer systems. To do this, he must switch off the circuits (C1–C3 in the screenshot above), and then switch off-and-on a circuit labeled “Main”.
It’s a good thing Arnold knows what he’s doing, since these switches are only labeled C1-3, and we don’t see any documentation in the camera frame. As he turns off each circuit, different parts of the computer terminals in the Control Room shut down. This implies that different computer banks are tied to the same power circuits as the systems they control.
So, since this is a major interface for the park, let’s make this bit explicit: When designing infrequently-used but mission-critical interfaces, take great care to explain use, using clear affordances and constraints so that mistakes are very, very difficult to make.
It might look like a mistake to have all the little electrical labeling to the sides, since this cover would have to be removed to get the components where this information would be of use. But that’s perfect. A user needing to remove this panel must encounter this reference information to get to those components, and so would know where to find them. This is a brilliant example of the pattern Put the Signal in the Path. Let’s hope there are similar signs on other access panels.
Wait…where are the backups?
These are the central computer terminals that run Jurassic Park, and keep visitors safe from the “attractions.” And there is no backup power.
When Arnold turns off the main circuit breaker, the computers (and servers behind them) turn off immediately. The purpose and effect of the power switch deactivates all the systems in Jurassic Park, without any kind of warning or backup system.
For something as dangerous as deadly deadly dinosaurs—raised from the 65 million-year deep grave of extinction—the system deactivation should at least trigger some kind of warning.
Tornado sirens have backup batteries in case the city power goes out. They are a solid example of a backup system that should exist, at minimum, to warn park-goers to move quickly towards shelter. A better backup system would be a duplicate server system that automatically activates all the fences in the park.
When Arnold cycles the visitor center’s power system, it also trips the breakers for all of the other power systems in the park. Primary safety systems like that should be on their own circuit. It’s ok if the fridges turn off and melt the ice cream (though it may be an inconvenience), but that same event shouldn’t also deactivate the velociraptor pen security. Especially when the ‘raptor pen is right next to the visitor center and is a known, aforementioned, deadly deadly threat.
After Loki gets away with the crazy-powerful tesseract and a handful of S.H.I.E.L.D. (seriously that’s a pain to type) agents, Fury has a virtual meeting with members of the World Security Council—which is shadowy in appearance and details. To conduct this furtive conference Fury walks into a room custom-built for such purposes.
A bank of large vertically-mounted monitors forms a semicircle in the small room, each mounted above a workstation with keyboard and multiple screens overlit for maximum eyestrain. It’s quite unclear what the agents who normally work here are currently doing, or what those vertically mounted screens normally display, since they’d be a shoo-in for an OSHA lawsuit, given the amount a user would need to crane. Ergonomics, Nick, look it up.
Each screen dedicates most of its real estate to a waist-up view of the speaker. Overlays near the bottom assure us that DATA [is] SECURE and confirms it with a 16-character alphanumeric CYPHER KEY that is frequently changing and unique to each speaker. This is similar to an HMAC-based One-time Password Algorithm (HOTP) password algorithm, so is well-grounded in reality. It’s convincing.
The screens adhere to the trope that every screen is a camera. Nick looks at their eyes and they look right back. Ordinarily that would be a big problem, but with the translucent displays and the edge lighting of the participants, it could actually work.
There is no indication of controls for these screens, but that’s cool if the room is dedicated to this purpose. Someone else would set the call up for him, and all he has to do is walk in. He should be able to just walk out to end it. And let them know how he feels about them.
Not everyone is comfortable giving over to the flimsy promise of Carrousel [sic]. Some citizens run, and Sandmen find and terminate these cultural heretics.
Sandmen carry a device with them that has many different uses. It goes unnamed in the movie, so let’s just call it the SandPhone. It is a thick black rectangle about 20cm at its long edge, about the size of a very large cell phone. Near the earpiece on one broad side is a small screen for displaying text and images. Below that is a white line. The lower half of this face is metallic grill that covers a microphone. On the left edge is a momentary button that allows talking. Just above this is a small red button. When not in use, the device is holstered on the sandman’s belt.
The SandPhone lets the Sandman receive information through a display that can show both image and text. The Sandman sends back information and requests by voice in a CB radio metaphor.
