Brain interfaces as wearables

There are lots of brain devices, and the book has a whole chapter dedicated to them. Most of these brain devices are passive, merely needing to be near the brain to have whatever effect they are meant to have (the chapter discusses in turn: reading from the brain, writing to the brain, telexperience, telepresence, manifesting thought, virtual sex, piloting a spaceship, and playing an addictive game. It’s a good chapter that never got that much love. Check it out.)

This is a composite SketchUp rendering of the shapes of all wearable brain control devices in the survey.

This is a composite rendering of the shapes of most of the wearable brain control devices in the survey. Who can name the “tophat”?

Since the vast majority of these devices are activated by, well, you know, invisible brain waves, the most that can be pulled from them are sartorial– and social-ness of their industrial design. But there are two with genuine state-change interactions of note for interaction designers.

Star Trek: The Next Generation

The eponymous Game of S05E06 is delivered through a wearable headset. It is a thin band that arcs over the head from ear to ear, with two extensions out in front of the face that project visuals into the wearer’s eyes.

STTNG The Game-02

The only physical interaction with the device is activation, which is accomplished by depressing a momentary button located at the top of one of the temples. It’s a nice placement since the temple affords placing a thumb beneath it to provide a brace against which a forefinger can push the button. And even if you didn’t want to brace with the thumb, the friction of the arc across the head provides enough resistance on its own to keep the thing in place against the pressure. Simple, but notable. Contrast this with the buttons on the wearable control panels that are sometimes quite awkward to press into skin.

Minority Report (2002)

The second is the Halo coercion device from Minority Report. This is barely worth mentioning, since the interaction is by the PreCrime cop, and it is only to extend it from a compact shape to one suitable for placing on a PreCriminal’s head. Push the button and pop! it opens. While it’s actually being worn there is no interacting with it…or much of anything, really.



Head: Y U No house interactions?

There is a solid physiological reason why the head isn’t a common place for interactions, and that’s that raising the hands above the heart requires a small bit of cardiac effort, and wouldn’t be suitable for frequent interactions simply because over time it would add up to work. Google Glass faced similar challenges, and my guess is that’s why it uses a blended interface of voice, head gestures, and a few manual gestures. Relying on purely manual interactions would violate the wearable principle of apposite I/O.

At least as far as sci-fi is telling us, the head is not often a fitting place for manual interactions.

Wearable Control Panels

As I said in the first post of this topic, exosuits and environmental suits are out of the definition of wearable computers. But there is one item commonly found on them that can count as wearable, and that’s the forearm control panels. In the survey these appear in three flavors.

Just Buttons

Fairly late in sci-fi they acknowledged the need for environmental suits, and acknowledged the need for controls on them. The first wearable control panel belongs to the original series of Star Trek, “The Naked Time” S01E04. The sparkly orange suits have a white cuff with a red and a black button. In the opening scene we see Mr. Spock press the red button to communicate with the Enterprise.

This control panel is crap. The buttons are huge momentary buttons that exist without a billet, and would be extremely easy to press accidentally. The cuff is quite loose, meaning Spock or the redshirt have to fumble around to locate it each time. Weeeeaak.

Star Trek (1966)


Some of these problems were solved when another WCP appeared 3 decades later in the the Next Generation movie First Contact.

Star Trek First Contact (1996)


This panel is at least anchored, and located in places that could be located fairly easily via proprioception. It seems to have a facing that acts as a billet, and so might be tough to accidentally activate. It’s counter to its wearer’s social goals, though, since it glows. The colored buttons help to distinguish it when you’re looking at it, but it sure makes it tough to sneak around in darkness. Also, no labels? No labels seems to be a thing with WCPs since even Pixar thought it wasn’t necessary.

The Incredibles (2004)

Admittedly, this WCP belonged to a villain who had no interest in others’ use of it. So that’s at least diegetically excusable.


Hey, Labels, that’d be greeeeeat

Zipping back to the late 1960s, Kubrick’s 2001 nailed most everything. Sartorial, easy to access and use (look, labels! color differentiation! clustering!), social enough for an environmental suit, billeted, and the inputs are nice and discrete, even though as momentary buttons they don’t announce their state. Better would have been toggle buttons.

2001: A Space Odyssey (1968)


Also, what the heck does the “IBM” button do, call a customer service representative from space? Embarrassing. What’s next, a huge Mercedez-Benz logo on the chest plate? Actually, no, it’s a Compaq logo.

A monitor on the forearm

The last category of WCP in the survey is seen in Mission to Mars, and it’s a full-color monitor on the forearm.

Mission to Mars


This is problematic for general use and fine for this particular application. These are scientists conducting a near-future trip to Mars, and so having access to rich data is quite important. They’re not facing dangerous Borg-like things, so they don’t need to worry about the light. I’d be a bit worried about the giant buttons that stick out on every edge that seem to be begging to be bumped. Also I question whether those particular buttons and that particular screen layout are wise choices, but that’s for the formal M2M review. A touchscreen might be possible. You might think that would be easy to accidentally activate, but not if it could only be activated by the fingertips in the exosuit’s gloves.


This isn’t an exhaustive list of every wearable control panel from the survey, but a fair enough recounting to point out some things about them as wearable objects.

  • The forearm is a fitting place for controls and information. Wristwatches have taken advantage of this for…some time. 😛
  • Socially, it’s kind of awkward to have an array of buttons on your clothing. Unless it’s an exosuit, in which case knock yourself out.
  • If you’re meant to be sneaking around, lit buttons are counterindicated. As are extruded switch surfaces that can be glancingly activated.
  • The fitness of the inputs and outputs depend on the particular application, but don’t drop the understandability (read: labels) simply for the sake of fashion. (I’m looking at you, Roddenberry.)

Fifth Element Day at the New Parkway is on!

9 P.M. Tuesday, 18 MAR 2014, $10, New Parkway Theater


Thanks to the fast action of connections on social media, we have the requisite numbers to cover the licensing costs to show The Fifth Element on 18 March at the New Parkway!


You’ll notice on the original page as well as this one that sales are being routed to Brown Paper Tickets. That’s the ticket sales service that New Parkway likes to work with. If you were one of the VIPs who ordered through, look for an email in your inbox over the next few days that confirms your name will be on a VIP Will-Call List at the door, cross-referenced with the email account you provided.


I’m certainly going to introduce myself and the movie to begin. Then I’ll offer up a little trivia game about the interfaces in the film. (Hint: This very blog might be the best place to shop for clues.) The reward for most correct answers will be a copy of Make It So 2nd edition print (with all those pesky errata from the 1st edition fixed.)


Stretch Goal

If we make it to 100 people, I’ll try to get my hands on one of the replica prop kits for a multipass, and offer that as another prize. Tell your friends and family and get us to 100 people!

If we make it past 100, and get to the max capacity of 140, I’ll come up with some other, even crazier stretch goal.

Scifiinterfaces content

After the trivia, there are a couple of things I could do. But I’ll put it to you, blog readers: What sounds best?

If there’s some other idea you’ve got to make this first scifiinterfaces movie night more fun than a Mangalore concert, drop it in the comments. I’ll check back occasionally on results, and finalize things sometime as we near the event.

Seriously, this is going to be supergreen.


Fifth Element Day at the New Parkway?

9 P.M. Tuesday, 18 MAR 2014, $10


Regular readers of the blog will recall that Korben Dallas’ Busy Day starts when he wakes up on 18 March 2263. This is also Director Luc Besson’s birthday, natch. Let’s celebrate this most incredible sci-fi film (with its most incredible interfaces) with a viewing on that most auspicious of days.


If we get enough people, we can get the rights to view it at the New Parkway Cinema in Oakland and enjoy the film the way it was meant to be enjoyed: With a bunch of other sci-fi nerds, on the big silver screen, with couches, beanbags, food, and a full bar (remember, Luc’s French.)


How many is enough people?

At $10 tickets, we need at least 50 to secure the rights and have the show. More than that and we get to thank New Parkway for working with me on such short notice. Much more than that and I can have a trivia contest with prizes. And if anyone’s interested, I could either play the Fifth-Element-centric pilot of Sci-Fi University beforehand, or maybe even a live, short-but-nerdy review of one of the other interfaces that appear everywhere in the film. I’ll get feedback on the site once it’s going.

When is the cutoff date?

There’s not a lot of time! We need that 50 as soon as possible so we can secure the cinema and the rights, etc. Ideally we could get that number by end of day today, 19 February. But that’s not a ton of time. So the final cutoff will be this Friday, 21 February 2014 at 4 P.M. Pacific Standard Time

Buy your tickets at Brown Paper Tickets. If we can’t get at least 50 people, you’re not charged. But once we get those 50, the thing’s happening, the sale goes through, and we let Korben Dallas and Leeloo save the universe one more time.


UPDATE1: My math was off by half. We need 50 for the licensing. I’ve changed the above, and if you’re wondering, it used to say 25.

UPDATE2: We made the numbers! It’s on!

What is the role of interaction design in the world of AI? (8/8)

Totally self-serving question. But weren’t you wondering it? What is the role of interaction design in the world of AI?

In a recent chat I had with Intel’s Futurist-Prime Genevieve Bell (we’re like, totally buds), she pointed out that Western cultures have more of a problem with the promise of AI than many others. It’s a Western cultural conceit that the reason humans are different—are valuable—is because we think. Contrast that with animist cultures, where everything has a soul and many things think. Or polytheistic cultures, where not only are there other things that think, but they’re humanlike but way more powerful than you. For these cultures, artificial intelligence means that technology has caught up with their cultural understandings. People build identities and live happy lives within these constructions just fine.

I’m also reminded of her keynote at Interaction12 where she spoke of the tendency of futurism to herald each new technology as ushering doomsday or utopia, when in hindsight it’s all terribly mundane. The internet is the greatest learning and connecting technology the world has ever created but for most people it’s largely cat videos. (Ah. That’s why that’s up there.) This should put us at ease about some of the more extreme predictions.

If Bell is right, and AIs are just going to be this other weird thing to incorporate into our lives, what is the role of the interaction designer?
