Kubris

Perhaps the most unusual interface in the film is a game seen when Theo visits his cousin Nigel for a meal and to ask for a favor. Nigel’’s son Alex sits at the table silent and distant, his attention on a strange game that it’s designer, Mark Coleran, tells me is called “Kubris,” a 3D hybrid of Tetris and Rubik’s Cube.

Alex operates the game by twitching and sliding his fingers in the air. With each twitch a small twang is heard. He suspends his hand a bit above the table to have room. His finger movements are tracked by thin black wires that extend from small plastic discs at his fingertips back to a device worn on his wrist. This device looks like a streamlined digital watch, but where the face of a clock would be are a set of multicolored LEDs arranged in rows.  These LEDs flicker on and off in inscrutable patterns, but clearly showing some state of the game. There is an inset LED block that also displays an increasing score.

Brain Upload

Once Johnny has installed his motion detector on the door, the brain upload can begin.

3. Building it

Johnny starts by opening his briefcase and removing various components, which he connects together into the complete upload system. Some of the parts are disguised, and the whole sequence is similar to an assassin in a thriller film assembling a gun out of harmless looking pieces.

It looks strange today to see a computer system with so many external devices connected by cables. We’ve become accustomed to one piece computing devices with integrated functionality, and keyboards, mice, cameras, printers, and headphones that connect wirelessly.

Cables and other connections are not always considered as interfaces, but “all parts of a thing which enable its use” is the definition according to Chris. In the early to mid 1990s most computer user were well aware of the potential for confusion and frustration in such interfaces. A personal computer could have connections to monitor, keyboard, mouse, modem, CD drive, and joystick – and every single device would use a different type of cable. USB, while not perfect, is one of the greatest ever improvements in user interfaces. Continue reading

Black & Decker Hydrator

BttF_113

Lorraine prepares the family a pizza using a hydrator. She opens a sealed foil package, branded “Pizza Hut,” and removes a tiny puck of a pizza, placing it in the center of a large pizza tray. She inserts the tray into a “hydrator” oven and closes the hinged front door. A small green light illuminates on its panel. She puts her mouth close to the device and instructs it to, “Hydrate level 4, please.” A red light illuminates as a bubbling sound is heard for a few seconds. Then a timer bell rings, and both lights extinguish. Lorraine removes a full-sized and fully-cooked pizza from the oven.

It could be improved by not having her have to remember and enter the level of hydration. There might be an argument that this helps the hydrator feel like they’re doing enough effort, like the legendary Betty Crocker egg story. While snopes tells us that the usual version of this is poppycock, but also references Ernest Dichter’s research in which yes, the first generation of homemakers using instant cake mixes felt that a preparation that was too easy was too indulgent. So, perhaps the hydrator is first generation, and later generations will be able to detect the hydration needed from the packaging.  

Thumbpay

Biff(2015) pays for his taxi ride to the McFly household with his thumbprint. When the ride ends, a synthesized voice gives the price “one-seven-four-point-five-zero.” The taxi driver presents him with a book-sized device with the price at the top on a red 7-segment LED display. Biff presses his thumb on a reader at the bottom that glows white as it scans. When the payment is verified, the thumbprint reader and the price go dark as a sound plays like a register.

For due diligence, let me restate: multimodal biometric or multifactor authentication is more secure.

Thumbknob

To get Jennifer into her home, the police take her to the front door of her home. They place her thumb on a small circular reader by the door. Radial LEDs circle underneath her thumb for a moment as it reads. Then a red light above the reader turns off and a green light turns on. The door unlocks and a synthesized voice says, “Welcome home, Jennifer!”

Similarly to the Thumbdentity, a multifactor authentication would be much more secure. The McFly family is struggling, so you might expect them to have substandard technology, but that the police are using something similar casts that in doubt.

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.

Ghost trap

Once ghosts are bound by the streams from the Proton Packs, they can be trapped by a special trap. It has two parts: The trap itself, that is roughly the size of a toaster, and the foot pedal activation switch, which connects to the trap box by a long black cord.

Trap02

To open the trap, a ghostbuster simple steps on the foot pedal. For a second the trap sparks with some unknown energy, and opens to reveal a supernatural light within. Once open, the bound ghost can be manipulated down towards the trap.

Proton Pack

Proton-Pack-02

The Ghostbusters wear “unlicensed particle accelerators” to shoot a stream of energy from an attached gun. Usefully, this positively-charged stream of energy can bind ghosts. The Pack is the size of a large camper’s backpack and is worn like one. The Proton pack must be turned on and warmed up before use. Its switch, oddly, is on the back, where the user cannot get to it themselves.

Compartment 21

After the Communications Tower is knocked off, Barcalow, looking out the viewport, somehow knows exactly where the damage to the ship has occured. This is a little like Captain Edward Smith looking out over the bow of the RMS Titanic and smelling which compartment was ripped open by the iceburg, but we must accept the givens of the scene. Barcalow turns to Ibanez and tells her to “Close compartment 21!” She turns to her left, reaches out, and presses a green maintained-contact button labeled ENABLE. This button is right next to a similar-but-black button also labeled ENABLE. As she presses the button, a nearby green LED flashes for a total of 4 frames, or 0.16 second.

She looks up at some unseen interface, and, pleased with what she sees there, begins to relax, the crisis passed.

A weary analysis

Let’s presume he is looking at some useful but out-of-character-for-this-bridge display, and that it does help him identify that yes, out of all the compartments that might have been the one they heard damaged, it is the 21st that needs closing.

  1. Why does he have the information but she have the control? Time is wasted (and air—not to mention lives, people—is lost) in the time it takes him to instruct and her to react.
  2. How did she find the right button when it’s labeled exactly the same way as adjacent button? Did she have to memorize the positions of all of them? Or the color? (How many compartments and therefore colors would that mean she would need to memorize?) Wouldn’t a label reading, say, “21” have been more useful in this regard?
  3. What good does an LED do to flash so quickly? Certainly, she would want to know that the instruction was received, but it’s a very fast signal. It’s easy to miss. Shouldn’t it have stayed on to indicate not the moment of contact, but the state?
  4. Why was this a maintained-contact button? Those look very similar when pressed or depressed. A toggle switch would display its state immediately, and would permit flipping a lot of them quickly, in case a lot of compartments need sealing.
  5. Why is there some second place she must look to verify the results of her action, that is a completely separate place from Barcalow (remember he looks forward, she looks up). Sure, maybe redundancy. Sure, maybe he’s looking at data and she’s looking at video feeds, but wouldn’t it be better if they were looking at the same thing?

I know it’s a very quick interaction. And props to the scriptwriters for thinking about leaking air in space. But this entire interaction needs rethinking.
