Agent Ross’ remote piloting

by

4

Remote operation appears twice during Black Panther. This post describes the second, in which CIA Agent Ross remote-pilots the Talon in order to chase down cargo airships carrying Killmonger’s war supplies. The prior post describes the first, in which Shuri remotely drives an automobile.

In this sequence, Shuri equips Ross with kimoyo beads and a bone-conducting communication chip, and tells him that he must shoot down the cargo ships down before they cross beyond the Wakandan border. As soon as she tosses a remote-control kimoyo bead onto the Talon, Griot announces to Ross in the lab “Remote piloting system activated” and creates a piloting seat out of vibranium dust for him. Savvy watchers may wonder at this, since Okoye pilots the thing by meditation and Ross would have no meditation-pilot training, but Shuri explains to him, “I made it American style for you. Get in!” He does, grabs the sparkly black controls, and gets to business.

The most remarkable thing to me about the interface is how seamlessly the Talon can be piloted by vastly different controls. Meditation brain control? Can do. Joystick-and-throttle? Just as can do.

Now, generally, I have a beef with the notion of hyperindividualized UI tailoring—it prevents vital communication across a community of practice (read more about my critique of this goal here)—but in this case, there is zero time for Ross to learn a new interface. So sure, give him a control system with which he feels comfortable to handle this emergency. It makes him feel more at ease.

The mutable nature of the controls tells us that there is a robust interface layer that is interpreting whatever inputs the pilot supplies and applying them to the actuators in the Talon. More on this below. Spoiler: it’s Griot.

Too sparse HUD

The HUD presents a simple circle-in-a-triangle reticle that lights up red when a target is in sights. Otherwise it’s notably empty of augmentation. There’s no tunnel in the sky display to describe the ideal path, or proximity warnings about skyscrapers, or airspeed indicator, or altimeter, or…anything. This seems a glaring omission since we can be certain other “American-style” airships have such things. More on why this might be below, but spoiler: It’s Griot.

What do these controls do, exactly?

I take no joy in gotchas. That said…

  • When Ross launches the Talon, he does so by pulling the right joystick backward.
  • When he shoots down the first cargo ship over Birnin Zana, he pushes the same joystick forward as he pulls the trigger, firing energy weapons.

Why would the same control do both? It’s hard to believe it’s modal. Extradiegetically, this is probably an artifact of actor Martin Freeman’s just doing what feels dramatic, but for a real-world equivalent I would advise against having physical controls have wholly different modes on the same grip, lest we risk confusing pilots on mission-critical tasks. But spoiler…oh, you know where this is going.

It’s Griot

Diegetically, Shuri is flat-out wrong that Ross is an experienced pilot. But she also knew that it didn’t matter, because her lab has him covered anyway. Griot is an AI with a brain interface, and can read Ross’ intentions, handling all the difficult execution itself.

This would also explain the lack of better HUD augmentation. That absence seems especially egregious considering that the first cargo ship was flying over a crowded city at the time it was being targeted. If Ross had fired in the wrong place, the cargo ship might have crashed into a building, or down to the bustling city street, killing people. But, instead, Griot quietly, precisely targets the ship for him, to insure that it would crash safely in nearby water.

This would also explain how wildly different interfaces can control the Talon with similar efficacy.

An stained-glass image of William of Ockham. A modern blackletter caption reads, “It was always Griot.”

So, Occams-apology says, yep, it’s Griot.

An AI-wizard did it?

In the post about Shuri’s remote driving, I suggested that Griot was also helping her execute driving behind the scenes. This hearkens back to both the Iron HUD and Doctor Strange’s Cloak of Levitation. It could be that the MCU isn’t really worrying about the details of its enabling technologies, or that this is a brilliant model for our future relationship with technology. Let us feel like heroes, and let the AI manage all the details. I worry that I’m building myself into a wizard-did-it pattern, inserting AI for wizard. Maybe that’s worth another post all its own.

But there is one other thing about Ross’ interface worth noting.

The sonic overload

When the last of the cargo ships is nearly at the border, Ross reports to Shuri that he can’t chase it, because Killmonger-loyal dragon flyers have “got me trapped with some kind of cables.” She instructs him to, “Make an X with your arms!” He does. A wing-like display appears around him, confirming its readiness.

Then she shouts, “Now break it!” he does, and the Talon goes boom shaking off the enemy ships, allowing Ross to continue his pursuit.

First, what a great gesture for this function. Very ordinarily, Wakandans are piloting the Talon, and each of them would be deeply familiar with this gesture, and even prone to think of it when executing a hail Mary move like this.

Second, when an outsider needed to perform the action, why didn’t she just tell Griot to just do it? If there’s an interpretation layer in the system, why not just speak directly to that controller? It might be so the human knows how to do it themselves next time, but this is the last cargo ship he’s been tasked with chasing, and there’s little chance of his officially joining the Wakandan air force. The emergency will be over after this instance. Maybe Wakandans have a principle that they are first supposed to engage the humans before bringing in the machines, but that’s heavy conjecture.

Third, I have a beef about gestures—there’s often zero affordances to tell users what gestures they can do, and what effects those gestures will have. If Shuri was not there to answer Ross’ urgent question, would the mission have just…failed? Seems like a bad design.

How else could have known he could do this? If Griot is on board, Griot could have mentioned it. But avoiding the wizard-did-it solutions, some sort of context-aware display could detect that the ship is tethered to something, and display the gesture on the HUD for him. This violates the principle of letting the humans be the heroes, but would be a critical inclusion in any similar real-world system.

Any time we are faced with “intuitive” controls that don’t map 1:1 to the thing being controlled, we’re faced with similar problems. (We’ve seen the same problems in Sleep Dealer and Lost in Space (1998). Maybe that’s worth its own write-up.) Some controls won’t map to anything. More problematic is that there will be functions which don’t have controls. Designers can’t rely on having a human cavalry like Shuri there to save the day, and should take steps to find ways that the system can inform users of how to activate those functions.

Fit to purpose?

I’ve had to presume a lot about this interface. But if those things are correct, then, sure, this mostly makes it possible for Ross, a novice to piloting, to contribute something to the team mission, while upholding the directive that AI Cannot Be Heroes.

If Griot is not secretly driving, and that directive not really a thing, then the HUD needs more work, I can’t diegetically explain the controls, and they need to develop just-in-time suggestions to patch the gap of the mismatched interface. 

Black Georgia Matters

Each post in the Black Panther review is followed by actions that you can take to support black lives. As this critical special election is still coming up, this is a repeat of the last one, modified to reflect passed deadlines.

The state flag of Georgia, whose motto clearly violates the doctrine of separation of church and state.
Always on my mind, or at least until July 06.

Despite outrageous, anti-democratic voter suppression by the GOP, for the first time in 28 years, Georgia went blue for the presidential election, verified with two hand recounts. Credit to Stacey Abrams and her team’s years of effort to get out the Georgian—and particularly the powerful black Georgian—vote.

But the story doesn’t end there. Though the Biden/Harris ticket won the election, if the Senate stays majority red, Moscow Mitch McConnell will continue the infuriating obstructionism with which he held back Obama’s efforts in office for eight years. The Republicans will, as they have done before, ensure that nothing gets done.

To start to undo the damage the fascist and racist Trump administration has done, and maybe make some actual progress in the US, we need the Senate majority blue. Georgia is providing that opportunity. Neither of the wretched Republican incumbents got 50% of the vote, resulting in a special runoff election January 5, 2021. If these two seats go to the Democratic challengers, Warnock and Ossof, it will flip the Senate blue, and the nation can begin to seriously right the sinking ship that is America.

What can you do?

If you live in Georgia, vote blue, of course. You can check your registration status online. You can also help others vote. Important dates to remember, according to the Georgia website…

  • 14 DEC Early voting begins
  • 05 JAN 2021 Final day of voting

Residents can also volunteer to become a canvasser for either of the campaigns, though it’s a tough thing to ask in the middle of the raging pandemic.

The rest of us (yes, even non-American readers) can contribute either to the campaigns directly using the links above, or to Stacey Abrams’ Fair Fight campaign. From the campaign’s web site:

We promote fair elections in Georgia and around the country, encourage voter participation in elections, and educate voters about elections and their voting rights. Fair Fight brings awareness to the public on election reform, advocates for election reform at all levels, and engages in other voter education programs and communications.

We will continue moving the country into the anti-racist future regardless of the runoff, but we can make much, much more progress if we win this election. Please join the efforts as best you can even as you take care of yourself and your loved ones over the holidays. So very much depends on it.

Black Reparations Matter

This is timely, so I’m adding this on as well rather than waiting for the next post: A bill is in the house to set up a commission to examine the institution of slavery and its impact and make recommendations for reparations to Congress. If you are an American citizen, please consider sending a message to your congresspeople asking them to support the bill.

Kimoyo Beads

by

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.

https://www.vote.org/

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.
