Deckard’s Front Door Key

I’m sorry. I could have sworn in advance that this would be a very quick post. One or two paragraphs.

  • Narrator
  • It wasn’t.

Exiting his building’s elevator, Deckard nervously pulls a key to his apartment from his wallet. The key is similar to a credit card. He inserts one end into a horizontal slot above the doorknob, and it quickly *beeps*, approving the key. He withdraws the key and opens the door.

The interaction…

…is fine, mostly. This is like a regular key, i.e. a physical token that is presented to the door to be read, and access granted or denied. If the interaction took longer than 0.1 second it would be important to indicate that the system was processing input, but it happens nearly instantaneously in the scene.

A complete review would need to evaluate other use cases.

  • How does it help users recover when the card is inserted incorrectly?
  • How does it reject a user when it is not the right key or the key has degraded too far to be read?

But of what we do see: the affordance is clear, being associated with the doorknob. The constraints help him know the card goes in lengthwise. The arrows help indicate which way is up and the proper orientation of the card. It could be worse.

A better interaction might arguably be no interaction, where he can just approach the door, and a key in his pocket is passively read, and he can just walk through. It would still need a second factor for additional security, and thinking through the exception use cases; but even if we nailed it, the new scene wouldn’t give him something to nervously fumble because Rachel is there, unnerving him. That’s a really charming character moment, so let’s give it a pass for the movie.

Accessibility

A small LED would help it be more accessible to deaf users to know if the key has been accepted or rejected.

The printing

The key has some printing on it. It includes the set of five arrows pointing the direction the key must be inserted. Better would be a key that either used physical constraints to make it impossible to insert the card incorrectly or to build the technology such that it could be read in any way it is inserted.

The rest of the card has numerals printed in MICR and words printed in a derived-from-MICR font like Data70. (MICR proper just has numerals.) MICR was designed such that the blobs on the letterforms, printed in magnetic ink, would be more easily detectible by a magnetic reader. It was seen as “computery” in the 1970s and 1980s (maybe still to some degree today) but does not make a lot of sense here when that part of the card is not available to the reader.

Privacy

Also on the key is his name, R. DECKARD. This might be useful to return the key to its rightful owner, but like the elevator passphrase, it needlessly shares personally identifiable information of its owner. A thief who found this key could do some social hacking with the name and gain access to his apartment. There is another possible solution for getting the key back to him if lost, discussed below.

The numbers underneath his name are hard to read, but a close read of the still frame and correlation across various prop recreations seem to agree it reads

015 91077
VP45 66-4020

While most of this looks like nonsense, the five-digit number in the upper right is obviously a ZIP code, which resolves to Arcadia, California, which is a city in Los Angeles county, where Blade Runner is meant to take place.

Though a ZIP code describes quite a large area, between this and the surname, it’s providing a potential identity thief too much.

Return if found?

There are also some Japanese characters and numbers on the graphic beneath his thumb. It’s impossible to read in the screen grab.

If I was consulting on this, I’d recommend—after removing the ZIP code—that this be how to return they key if it is found, so that it could be forwarded, by the company, to the owner. All the company would have to do is cross-reference the GUID on the key to the owner. It would be a nice nod to the larger world.

(Repeated for easy reference.)

The holes

You can see there are also holes punched in the card. (re: the light dots in the shadow in the above still.) They must not be used in this interaction because his thumb is covering so much of them. They might provide an additional layer of data, like the early mechanical key card systems. This doesn’t satisfy either of the other aspects of multifactor authentication, though, since it’s still part of the same physical token.

This…this is altered.

I like to think this is evidence that this card works something like a Multipass from The Fifth Element, providing identity for a wide variety of services which may have different types of readers. We just don’t see it in the film.

Security

Which brings us, as so many things do in sci-fi interfaces, back to multi-factor authentication. The door would be more secure if it required two of the three factors. (Thank you Seth Rosenblatt and Jason Cipriani for this well-worded rule-of-thumb)

  • Knowledge (something the user and only the user knows)
  • Possession (something the user and only the user has)
  • Inherence (something the user and only the user is)

The key counts as a possession factor. Given the scene just before in the elevator, the second factor could be another voiceprint for inherence. It might be funny to have him say the same phrase I suggested in that post, “Have you considered life in the offworld colonies?” with more contempt or even embarrassment that he has to say something that demeaning in front of Rachel.

Now, I’d guess most people in the audience secure their own homes simply with a key. More security is available to anyone with the money, but economics and the added steps for daily usage prevent us from adopting more. So, adding second factor, while more secure, might read to the audience as an indicator of wealth, paranoia, or of living in a surveillance state, none of which would really fit Blade Runner or Deckard. But I would be remiss if I didn’t mention it.

St. God’s: Healthmaster Inferno

After Joe goes through triage, he is directed to the “diagnosis area to the right.” He waits in a short queue, and then enters the diagnosis bay.

The attendant wears a SMARTSPEEK that says, “Your illness is very important to us. Welcome to the Healthmaster Inferno.”

The attendant, DR. JAGGER, holds three small metal probes, and hands each one to him in turn saying, “Uh, this one goes in your mouth. This one goes in your ear. And this one goes up your butt.” (Dark side observation about the St. God’s: Apparently what it takes to become a doctor in Idiocracy is an ability to actually speak to patients and not just let the SMARTSPEEK do all the talking.)

Joe puts one in his mouth and is getting ready to insert the rest, when a quiet beeping causes the attendant to pause and correct himself. “Shit. Hang on a second.” He takes the mouth one back and hands him another one. “This one…No.” He gathers them together, and unable to tell them apart, he shuffles them trying to figure it out, saying “This one. This one goes in your mouth.” Joe reluctantly puts the offered probe into his mouth and continues.

The diagnosis is instant (and almost certainly UNKNOWN). SMARTSPEEK says, “Thank you for waiting. Dr. Lexus will be with you shortly.”

Remote wingman via EYE-LINK

EYE-LINK is an interface used between a person at a desktop who uses support tools to help another person who is live “in the field” using Zed-Eyes. The working relationship between the two is very like Vika and Jack in Oblivion, or like the A.I. in Sight.

In this scene, we see EYE-LINK used by a pick-up artist, Matt, who acts as a remote “wingman” for pick-up student Harry. Matt has a group video chat interface open with paying customers eager to lurk, comment, and learn from the master.

Harry’s interface

Harry wears a hidden camera and microphone. This is the only tech he seems to have on him, only hearing his wingman’s voice, and only able to communicate back to his wingman by talking generally, talking about something he’s looking at, or using pre-arranged signals.

Tap your beer twice if this is more than a little creepy.

Matt’s interface

Matt has a three-screen setup:

  1. A big screen (similar to the Samsung Series 9 displays) which shows a live video image of Harry’s view.
  2. A smaller transparent information panel for automated analysis, research, and advice.
  3. An extra, laptop-like screen where Matt leads a group video chat with a paying audience, who are watching and snarkily commenting on the wingman scenario. It seems likely that this is not an official part of the EYE-LINK software.

Hotel Remote

The Internet 2021 shot that begins the film ends in a hotel suite, where it wakes up lead character Johnny. This is where we see the first real interface in the film. It’s also where this discussion gets more complicated.

A note on my review strategy

As a 3D graphics enthusiast, I’d be happy just to analyze the cyberspace scenes, but when you write for Sci Fi Interfaces, there is a strict rule that every interface in a film must be subjected to inspection. And there are a lot of interfaces in Johnny Mnemonic. (Curse your exhaustive standards, Chris!)

A purely chronological approach which would spend too much time looking at trees and not enough at the forest. So I’ll be jumping back and forth a bit, starting with the gadgets and interfaces that appear only once, then moving on to the recurring elements, variations on a style or idea that are repeated during the film.

Description

The wakeup call arrives in the hotel room as a voice announcement—a sensible if obvious choice for someone who is asleep—and also as text on a wall screen, giving the date, time, and temperature. The voice is artificial sounding but pleasant rather than grating, letting you know that it’s a computer and not some hotel employee who let himself in. The wall display functions as both a passive television and an interactive computer monitor. Johnny picks up a small remote control to silence the wake up call.

jm-2-check-email-a

This remote is a small black box like most current-day equivalents, but with a glowing red light at one end. At the time of writing blue lights and indicators are popular for consumer electronics, apparently following the preference set by science fiction films and noted in Make It So. Johnny Mnemonic is an outlier in using red lights, as we’ll see more of these as the film progresses. Here the glow might be some kind of infrared or laser beam that sends a signal, or it might simply indicate the right way to orient the control in the hand for the controls to make sense.

Explorer Surveillance

The Control Room of Jurassic Park has a basic video/audio feed to the Tour Explorers that a controller (or, in this case, John Hammond) can use to talk to the tour participants.  He is able to switch to different cameras using the number keys on the keyboard attached to the monitor. The cameras themselves appear to be fixed in place.

JurassicPark_FordSurveillance01

We never see the cameras themselves in the Explorers, but we do see Malcolm tap on one of the cameras during the tour while Hammond is watching it’s feed, so they are visible to the riders.

Hammond occasionally speaks through his audio link, and can hear a constant audio feed from the Explorers. He has some kind of mute button (he says a couple disparaging comments that the other characters don’t appear to hear), but the feed from the Explorers is real-time. It isn’t obvious how he switches between the different Explorers’ audio feeds, or whether he hears both Explorers simultaneously. Continue reading

Dome City Rail

LogansRunCar-08

Citizens move between the distant parts of the city by means of a free, public transportation system. It is an ultra-light rail, featuring cars for two passengers, that move between long translucent tubes that connect the domes of the city. When one car stops at a station, its door slides open to allow exit and entry. We never see a car waiting behind another. Once seated, riders press a red button on a panel between the two seats (just visible in the screen capture below), and the car seals shut and takes off to the next station.

LogansRunCar-04

LogansRun144

A small panel inside the car alerts passengers to the name of the next stop as well as any additional information that is of use. When Logan and Jessica head to Cathedral Station, the panel blinks a red light to draw their attention. (The paired green light is never seen illuminated. What’s it there for?) A female voice says “Entering a reservation for violent delinquents. Authorized persons only.” The screen before them reads, “personal risk area.” (For those wondering why it stops there at all, anyone can get out of their car here, but Logan has to use his personal communication device with Control to have the gate to Cathedral opened.

Eepholes

TheFifthElement-police-027

Please forgive the title. It’s a portmanteau of “e” and “peepholes” that was too goofy to resist and not part of the official Fifth Element canon.

When the police have an apartment in lockdown, they have a special tool to evaluate individual citizens in their apartments. It’s an electronic peephole that allows them to see and communicate with the citizen inside their apartment. To use it, a police officer places a handheld device shaped something like an iron up to the door near eye height. Pressing a button at the thumb switches a status light from green to red and opens an electronic “hole” in the door, through which the officer can see, but out of which the citizen cannot.

TheFifthElement-police-029

While the eephole is activated, the intercom between the yellow circles in which the citizen has placed his or her hands glows orange, letting them know that the call is active. Then the officer can freely interrogate the citizen.

Officer: Sir, are you classified as human?
Korben: Negative. I am a meat popsicle.

Analysis

How the device works is something of a mystery, but we have to take its results at face value. We’re concerned about the interaction, and that works OK. The device has a single handle and flat plate that fits against the door readily. The thumb button is placed so it’s easy to activate while holding it up with one hand. The fact that it’s portable rather than embedded in the door means that it can be taken away by the police after their business is done, rather than leaving it there to be hacked.

If I had to make any improvements, I would hope to make the device stick to the door so the officer could have both hands ready for his weapon should he need it, or feel more free to dodge out of the way. I would also omit any of the many glowing lights that appear extraneous, at least to what we see in this scene. I might also provide some output to the officer that the interaction is under warrant, or maybe even that it’s being being recorded, to remind them not to abuse this breach of privacy. Clearly it causes stress among the citizens subject to it.
