OS1 as a wearable computer (4/8)

In Make It So, I posited my definition of an interface as “all parts of a thing that enable its use,” and I still think it’s a useful one. With this definition in mind, we can speak of each of those components and capabilities above (less the invisible ones) and evaluate its parts according to the criteria I’ve posited for all wearable technology:

  • Sartorial (materially suitable for wearing)
  • Social (fits into our social lives)
  • Easy to access and use
  • Tough to accidentally activate
  • Having apposite inputs and outputs (suitable for use while being worn)



It’s sartorial and easy to access/use. It’s ergonomic, well designed for grabbing, fitting into the ear canal, staying in place, and pulling back out again. Its speakers produce perfect sound and the wirelessness makes it as unobtrusive as it can be without being an implant.

It’s slightly hidden as a social signal, and casual observers might think the user is speaking to himself. This has, in the real world, become less and less of a social stigma, and in the world of Her, it’s ubiquitous, so that’s not a problem for that culture.

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.

War game equipment


The recruits practice their war skills with capture the flag games. Each participant carries visible-laser weapons (color coded to match the team color) to fire at members of the other team, and wears a special vest that detects when it is hit with a laser, flashing briefly with red lights on the front and back and thereafter delivering a debilitating shock to the wearer until the game is over.

Jack’s Bike


Jack’s Bike is a compact, moto-cross-like motorcycle. It’s stored folded up in a rear cargo area of the Bubbleship when not in use. To get it ready to ride Jack:

  1. Unlocks the cargo pod from a button on his wrist
  2. Pulls it out of the Bubbleship
  3. Unfolds its components (which lock automatically into place)
  4. Rides off.

When Jack mounts the bike it automatically powers on and is ready to ride.

Night Vision Goggles


Genarro: “Are they heavy?”
Excited Kid: “Yeah!”
Genarro: “Then they’re expensive, put them back”
Excited Kid: [nope]

The Night Vision Goggles are large binoculars that are sized to fit on an adult head.  They are stored in a padded case in the Tour Jeep’s trunk.  When activated, a single red light illuminated in the “forehead” of the device, and four green lights appear on the rim of each lens. The green lights rotate around the lens as the user zooms the binoculars in and out. On a styling point, the goggles are painted in a very traditional and very adorable green and yellow striped dinosaur pattern.

Tim holds the goggles up as he plays with them, and it looks like they are too large for his head (although we don’t see him adjust the head support at all, so he might not have known they were adjustable).  He adjusts the zoom using two hidden controls—one on each side.  It isn’t obvious how these work. It could be that…

  • There are no controls, and it automatically focuses on the thing in the center of the view or on the thing moving.
  • One side zooms in, and the other zooms out.
  • Both controls have a zoom in/zoom out ability.
  • Each side control powers its own lens.
  • Admittedly, the last option is the least likely.

Unfortunately the movie just doesn’t give us enough information, leaving it as an exercise for us to consider.

The Jacket


Dr. Brown gives Marty some 21st century clothes in order to blend in. The first is the pair of Nike MAGs. The other item of clothing Marty must don is a jacket. It has two functions. When Marty first tries it on, the sleeves are nearly twice as long as they ought to be. After complaining that it doesn’t fit, Dr. Brown reaches and pinches a blinking and beeping red LED at the base of the jacket’’s zipper. In response, the sleeves retract to a proper length, the pocket flaps shrink, and the epaulettes flatten out as a synthesized voice states, ““Adjusting fit.”

Wearable soundboard

One of Griff Tannan’’s gang, named Data, wears a sound board on his vest. When Tannan gets a rise out of Marty by asking if he’’s “chicken,” the gang member underscores the accusation by removing a protective plate over some buttons on his vest and holds one down to play a looping sound clip of a clucking chicken.


That’s pretty awesome, actually. Having all the sounds available at the touch of a button adds a layer of remix culture expressiveness with maximum speed. No modes, no menus, just remembering which sound goes with which button, and his spatial memory is perfect for that. If the buttons were labeled with the sound, or shaped informatively, it might reduce the burden on memory.


You might also reduce the time it takes to respond by removing the protective plate, but Griff is enough of a loose cannon that he might go violent if an accidental sound effect insulted him. So that extra step is probably the safest.

But if we were to really make this it’s most awesome, you’d make it agentive, such that the plate constantly listened to the conversation for keywords or keyphrases and responded with appropriate snarky sound effects. (Smartphone startup founded around this idea in 3…2…1…)
