The Dark Dimension mode (5/5)

We see a completely new mode for the Eye in the Dark Dimension. With a flourish of his right hand over his left forearm, a band of green lines begin orbiting his forearm just below his wrist. (Another orbits just below his elbow, just off-camera in the animated gif.) The band signals that Strange has set this point in time as a “save point,” like in a video game. From that point forward, when he dies, time resets and he is returned here, alive and well, though he and anyone else in the loop is aware that it happened.


In the scene he’s confronting a hostile god-like creature on its own mystical turf, so he dies a lot.

Tibet mode: Display for interestingness (2 of 5)

Without a display, the Eye asks Strange to do all the work of exploring the range of values available through it to discover what is of interest. (I am constantly surprised at how many interfaces in the real world repeat this mistake.) We can help by doing a bit of “pre-processing” of the information and provide Strange a key to what he will find, and where, and ways to recover exactly where interesting things happen.


The watch from the film, for reasons that will shortly become clear.

To do this, we’ll add a ring outside the saucer that will stay fixed relative to the saucer’s rotation and contain this display. Since we need to call this ring something, and we’re in the domain of time, let’s crib some vocabulary from clocks. The fixed ring of a clock that contains the numbers and minute graduations is called a chapter ring. So we’ll use that for our ring, too.


What chapter ring content would most help Strange? Continue reading

Jasper’s Music Player


After Jasper tells a white lie to Theo, Miriam, and Kee to get them to escape the advancing gang of Fishes, he returns indoors. To set a mood, he picks up a remote control and presses a button on it while pointing it at a display.


He watches a small transparent square that rests atop some things in a nook. (It’s that decimeter-square, purplish thing on the left of the image, just under the lampshade.) The display initially shows an album queue, with thumbnails of the album covers and two bright words, unreadably small. In response to his button press, the thumbnail for Franco Battiato’s album FLEURs slides from the right to the left. A full song list for the album appears beneath the thumbnail. Then track two, the cover of Ruby Tuesday, begins to play. A small thumbnail to the right of the album cover appears, featuring some white text on a dark background and a cycling, animated border. Theo puts the remote control down, picks up the Quietus box, and walks over to Janice. *sniff*

This small bit of speculative consumer electronics gets around 17 seconds of screen time, but we see enough to consider the design.  Continue reading

Scenery display

BttF_096Jennifer is amazed to find a window-sized video display in the future McFly house. When Lorraine arrives at the home, she picks up a remote to change the display. We don’t see it up close, but it looks like she presses a single button to change the scene from a sculpted garden to one of a beach sunset, a city scape, and a windswept mountaintop. It’s a simple interface, though perhaps more work than necessary.

We don’t know how many scenes are available, but having to click one button to cycle through all of them could get very frustrating if there’s more than say, three. Adding a selection ring around the button would allow the display to go from a selected scene to a menu from which the next one might be selected from amongst options.


The first computer interface we see in the film occurs at 3:55. It’s an interface for housing and monitoring the tesseract, a cube that is described in the film as “an energy source” that S.H.I.E.L.D. plans to use to “harness energy from space.” We join the cube after it has unexpectedly and erratically begun to throw off low levels of gamma radiation.

The harnessing interface consists of a housing, a dais at the end of a runway, and a monitoring screen.


Fury walks past the dais they erected just because.

The housing & dais

The harness consists of a large circular housing that holds the cube and exposes one face of it towards a long runway that ends in a dais. Diegetically this is meant to be read more as engineering than interface, but it does raise questions. For instance, if they didn’t already know it was going to teleport someone here, why was there a dais there at all, at that exact distance, with stairs leading up to it? How’s that harnessing energy? Wouldn’t you expect a battery at the far end? If they did expect a person as it seems they did, then the whole destroying swaths of New York City thing might have been avoided if the runway had ended instead in the Hulk-holding cage that we see later in the film. So…you know…a considerable flaw in their unknown-passenger teleportation landing strip design. Anyhoo, the housing is also notable for keeping part of the cube visible to users near it, and holding it at a particular orientation, which plays into the other component of the harness—the monitor.

Precrime forearm-comm


Though most everyone in the audience left Minority Report with the precrime scrubber interface burned into their minds (see Chapter 5 of the book for more on that interface), the film was loaded with lots of other interfaces to consider, not the least of which were the wearable devices.

Precrime forearm devices

These devices are worn when Anderton is in his field uniform while on duty, and are built into the material across the left forearm. On the anterior side just at the wrist is a microphone for communications with dispatch and other officers. By simply raising that side of his forearm near his mouth, Anderton opens the channel for communication. (See the image above.)


There is also a basic circular display in the middle of the posterior left forearm that displays a countdown for the current mission: The time remaining before the crime that was predicted to occur should take place. The text is large white characters against a dark background. Although the translucency provides some visual challenge to the noisy background of the watch (what is that in there, a Joule heating coil?), the jump-cut transitions of the seconds ticking by commands the user’s visual attention.

On the anterior forearm there are two visual output devices: one rectangular perpetrator information (and general display?) and one amber-colored circular one we never see up close. In the beginning of the film Anderton has a man pinned to the ground and scans his eyes with a handheld Eyedentiscan device. Through retinal biometrics, the pre-offender’s identity is confirmed and sent to the rectangular display, where Anderton can confirm that the man is a citizen named Howard Marks.

Wearable analysis

Checking these devices against the criteria established in the combadge writeup, it fares well. This is partially because it builds on a century of product evolution for the wristwatch.

It is sartorial, bearing displays that lay flat against the skin connected to soft parts that hold them in place.

They are social, being in a location other people are used to seeing similar technology.

It is easy to access and use for being along the forearm. Placing different kinds of information at different spots of the body means the officer can count on body memory to access particular data, e.g. Perp info is anterior middle forearm. That saves him the cognitive load of managing modes on the device.

The display size for this rectangle is smallish considering the amount of data being displayed, but being on the forearm means that Anderton can adjust its apparent size by bringing it closer or farther from his face. (Though we see no evidence of this in the film, it would be cool if the amount of information changed based on distance-to-the-observer’s face. Writing that distanceFromFace() algorithm might be tricky though.)

There might be some question about accidental activation, since Anderton could be shooting the breeze with his buddies while scratching his nose and mistakenly send a dirty joke to a dispatcher, but this seems like an unlikely and uncommon enough occurrence to simply not worry about it.

Using voice as the input is cinemagenic, but especially in his line of work a subvocalization input would keep him more quiet—and therefore safer— in the field. Still, voice inputs are fast and intuitive, making for fairly apposite I/O. Ideally he might have some haptic augmentation of the countdown, and audio augmentation of the info so Anderton wouldn’t have to pull his arm and attention away from the perpetrator, but as long as the information is glanceable and Anderton is merely confirming data (rather than new information), recognition is a fast enough cognitive process that this isn’t too much of a problem.

All in all, not bad for a “throwaway” wearable technology.
