Deckard’s Elevator

3 Mar 2020 by Christopher Noessel

This is one of those interactions that happens over a few seconds in the movie, but turns out to be quite deep—and broken—on inspection.

When Deckard enters his building’s dark, padded elevator, a flat voice announces, “Voice print identification. Your floor number, please.” He presses a dark panel, which lights up in response. He presses the 9 and 7 keys on a keypad there as he says, “Deckard. 97.” The voice immediately responds, “97. Thank you.” As the elevator moves, the interface confirms the direction of travel with gentle rising tones that correspond to the floor numbers (mod 10), which are shown rising up a 7-segment LED display. We see a green projection of the floor numbers cross Deckard’s face for a bit until, exhausted, he leans against the wall and out of the projection. When he gets to his floor, the door opens and the panel goes dark.

A need for speed

An aside: To make 97 floors in 20 seconds you have to be traveling at an average of around 47 miles per hour. That’s not unheard of today. Mashable says in a 2014 article about the world’s fastest elevators that the Hitachi elevators in Guangzhou CTF Finance Building reach up to 45 miles per hour. But including acceleration and deceleration adds to the total time, so it takes the Hitachi elevators around 43 seconds to go from the ground floor to their 95th floor. If 97 is Deckard’s floor, it’s got to be accelerating and decelerating incredibly quickly. His body doesn’t appear to be suffering those kinds of Gs, so unless they have managed to upend Newton’s basic laws of motion, something in this scene is not right. As usual, I digress.

The input control is OK

The panel design is nice and was surprising in 1982, because few people had ridden in elevators serving nearly a hundred floors. And while most in-elevator panels have a single button per floor, it would have been an overwhelming UI to present the rider of this Blade Runner complex with 100 floor buttons plus the usual open door, close door, emergency alert buttons, etc. A panel that allows combinatorial inputs reduces the number of elements that must be displayed and processed by the user, even if it slows things down, introduces cognitive overhead, and adds the need for error-handling. Such systems need a “commit” control that allows them to review, edit, and confirm the sequence, to distinguish, say, “97” from “9” and “7.” Not such an issue from the 1st floor, but a frustration from 10–96. It’s not clear those controls are part of this input.

Deckard enters 8675309, just to see what will happen.

I’m a fan of destination dispatch elevator systems that increase efficiency (with caveats) by asking riders to indicate their floor outside the elevator and letting the algorithm organize passengers into efficient groups, but that only works for banks of elevators. I get the sense Deckard’s building is a little too low-rent for such luxuries. There is just one in his building, and in-elevator controls work fine for those situations, even if they slow things down a bit.

The feedback is OK

The feedback of the floors is kind of nice in that the 7-segment numbers rise up helping to convey the direction of movement. There is also a subtle, repeating, rising series of tones that accompany the display. Most modern elevators rely on the numeracy of its passengers and their sense of equilibrium to convey this information, but sure, this is another way to do it. Also, it would be nice if the voice system would, for the visually impaired, say the floor number when the door opens.

Though the projection is dumb

I’m not sure why the little green projection of the floor numbers runs across Deckard’s face. Is it just a filmmaker’s conceit, like the genetic code that gets projected across the velociraptors head in Jurassic Park?

Pictured: Sleepy Deckard. Dumb projection.

Or is it meant to be read as diegetic, that is, that there is a projector in the elevator, spraying the floor numbers across the faces of its riders? True to the New Criticism stance of this blog, I try very hard to presume that everything is diegetic, but I just can’t make that make sense. There would be much better ways to increase the visibility of the floor numbers, and I can’t come up with any other convincing reason why this would exist.

If *this* was diegetic, the scene would have ended with a shredded projector.

But really, it falls apart on the interaction details

Lastly, this interaction. First, let’s give it credit where credit is due. The elevator speaks clearly and understands Deckard perfectly. No surprise, since it only needs to understand a very limited number of utterances. It’s also nice that it’s polite without being too cheery about it. People in LA circa 2019 may have had a bad day and not have time for that shit.

Where’s the wake word?

But where’s the wake word? This is a phrase like “OK elevator” or “Hey lift” that signals to the natural language system that the user is talking to the elevator and not themselves, or another person in the elevator, or even on the phone. General AI exists in the Blade Runner world, and that might allow an elevator to use contextual cues to suss this out, but there are zero clues in the film that this elevator is sentient.

There are of course other possible, implicit “wake words.” A motion detector, proximity sensor, or even weight sensor could infer that a human is present, and start the elevator listening. But with any of these implicit “wake words,” you’d still need feedback for the user to know when it was listening. And some way to help them regain attention if they got the first interaction wrong, and there would be zero affordances for this. So really, making an explicit wake word is the right way to go.

It might be that touching the number panel is the attention signal. Touch it, and the elevator listens for a few seconds. That fits in with the events in the scene, anyway. The problem with that is the redundancy. (See below.) So if the solution was pressing a button, it should just be a “talk” button rather than a numeric keypad.

It may be that the elevator is always listening, which is a little dark and would stifle any conversation in the elevator less everyone end up stuck in the basement, but this seems very error prone and unlikely.

Deckard: *Yawns* Elevator: Confirmed. Silent alarm triggered.

This issue is similar to the one discussed in Make It So Chapter 5, “Gestural Interfaces” where I discussed how a user tells a computer they are communicating to it with gestures, and when they aren’t.

Where are the paralinguistics?

Humans provide lots of signals to one another, outside of the meaning of what is actually being said. These communication signals are called paralinguistics, and one of those that commonly appears in modern voice assistants is feedback that the system is listening. In the Google Assistant, for example, the dots let you know when it’s listening to silence and when it’s hearing your voice, providing implicit confirmation to the user that the system can hear them. (Parsing the words, understanding the meaning, and understanding the intent are separate, subsequent issues.)

Fixing this in Blade Runner could be as simple as turning on a red LED when the elevator is listening, and varying the brightness with Deckard’s volume. Maybe add chimes to indicate the starting-to-listen and no-longer-listening moments. This elevator doesn’t have anything like that, and it ought to.

Why the redundancy?

Next, why would Deckard need to push buttons to indicate “97” even while he’s saying the same number as part of the voice print? Sure, it could be that the voice print system was added later and Deckard pushes the numbers out of habit. But that bit of backworlding doesn’t buy us much.

It might be a need for redundant, confirming input. This is useful when the feedback is obscure or the stakes are high, but this is a low-stakes situation. If he enters the wrong floor, he just has to enter the correct floor. It would also be easy to imagine the elevator would understand a correction mid-ride like “Oh wait. Elevator, I need some ice. Let’s go to 93 instead.” So this is not an interaction that needs redundancy.

It’s very nice to have the discrete input as accessibility for people who cannot speak, or who have an accent that is unrecognizable to the system, or as a graceful degradation in case the speech recognition fails, but Deckard doesn’t fit any of this. He would just enter and speak his floor.

Why the personally identifiable information?

If we were designing a system and we needed, for security, a voice print, we should protect the privacy of the rider by not requiring personally identifiable information. It’s easy to imagine the spoken name being abused by stalkers and identity thieves riding the elevator with him. (And let’s not forget there is a stalker on the elevator with him in this very scene.)

This young woman, for example, would abuse the shit out of such information.

Better would be some generic phrase that stresses the parts of speech that a voiceprint system would find most effective in distinguishing people.

Tucker Saxon has written an article for VoiceIt called “Voiceprint Phrases.” In it he notes that a good voiceprint phrase needs some minimum number of non-repeating phonemes. In their case, it’s ten. A surname and a number is rarely going to provide that. “Deckard. 97,” happens to have exactly 10, but if he lived on the 2nd floor, it wouldn’t. Plus, it has that personally identifiable information, so is a non-starter.

What would be a better voiceprint phrase for this scene? Some of Saxon’s examples in the article include, “Never forget tomorrow is a new day” and “Today is a nice day to go for a walk.” While the system doesn’t care about the meaning of the phrase, the humans using it would be primed by the content, and so it would just add to the dystopia of the scene if Deckard had to utter one of these sunshine-and-rainbows phrases in an elevator that was probably an uncleaned murder scene. but I think we can do it one better.

(Hey Tucker, I would love use VoiceIt’s tools to craft a confirmed voiceprint phrase, but the signup requires that I permit your company to market to me via phone and email even though I’m just a hobbyist user, so…hard no.)

Deckard: Hi, I’m Deckard. My bank card PIN code is 3297. The combination lock to my car spells “myothercarisaspinner” and my computer password is “unicorn.” 97 please.

Here is an alternate interaction that would have solved a lot of these problems.

ELEVATOR
Voice print identification, please.
DECKARD
SIGHS
DECKARD
Have you considered life in the offworld colonies?
ELEVATOR
Confirmed. Floor?
DECKARD
97

Which is just a punch to the gut considering Deckard is stuck here and he knows he’s stuck, and it’s salt on the wound to have to repeat fucking advertising just to get home for a drink.

So…not great

In total, this scene zooms by and the audience knows how to read it, and for that, it’s fine. (And really, it’s just a setup for the moment that happens right after the elevator door opens. No spoilers.) But on close inspection, from the perspective of modern interaction design, it needs a lot of work.

Thumbpay

21 Oct 2015 by Christopher Noessel

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

21 Oct 2015 by Christopher Noessel

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.

Sleep Pod—Wake Up Countdown

5 Mar 2015 by Maximiliano Pena

On each of the sleep pods in which the Odyssey crew sleep, there is a display for monitoring the health of the sleeper. It includes some biometric charts, measurements, a body location indicator, and a countdown timer. This post focuses on that timer.

To show the remaining time of until waking Julia, the pod’s display prompts a countdown that shows hours, minutes and seconds. It shows in red the final seconds while also beeping for every second. It pops-up over the monitoring interface.

Julia’s timer reaches 0:00:01.

The thing with pop-ups

We all know how it goes with pop-ups—pop-ups are bad and you should feel bad for using them. Well, in this case it could actually be not that bad.

The viewer

Although the sleep pod display’s main function is to show biometric data of the sleeper, the system prompts a popup to show the remaining time until the sleeper wakes up. And while the display has some degree of redundancy to show the data—i.e. heart rate in graphics and numbers— the design of the countdown brings two downsides for the viewer.

Position: it’s placed right in the middle of the screen.
Size: it’s roughly a quarter of the whole size of the display

Between the two, it partially covers both the pulse graphics and the numbers, which can be vital, i.e. life threatening—information of use to the viewer. Continue reading →

The Evidence Tray (ordinary use)

18 Nov 2013 by Christopher Noessel

Sandmen surrender any physical objects recovered from the bodies of runners to the Übercomputer for evaluation via a strange device I’m calling The Evidence Tray.

As a Sandman enters the large interrogation chamber, a transparent cylinder lowers from the ceiling. At the top of this cylinder an arm continuously rotates bearing four pin lights. A chrome cone sits in the center of the base. The Sandman can access the interior of the cylinder through a large oblong opening in the side the top of which is just taller than Sandmen (who seem to be a near-uniform height).

The Sandman puts any evidence he has found into the bottom of this cylinder. (What if the evidence was too large to fit? What if the critical evidence is not physical, or ephemeral? But I digress.) In response to his placing the objects, lights on the rotating arm illuminate, scanning them. The voice of the Übercomputer prompts the Sandman to “identify,” a request that is repeated on a large screen mounted on the wall in view through the transparent backing of the Evidence Tray.

The Sandman identifies himself by placing his palm on a cone in the cylinder’s center, positioning his lifeclock in the small indention in its tip. The base section of the cylinder illuminates, and after a pause, the voice and screen confirm that his identity has been “affirmed.” Logan removes his hand, and in a flash of blue light the objects in the tray disappear. The film gives no clue as to whether the objects are teleported somewhere or disintegrated into thin air.

Objections

There are of course the usual objections to the authentication. The lifeclock check is really a biometric check, something that Logan “is” (since he can’t remove the lifeclock) and—per the principles of multifactor authentication—should need to provide an additional factor, such as something he has (like a key) and something he knows (like a password).

There’s another objection there to the fact that the authentication requires that his hand be put into a teleport/distingration chamber. Perhaps narratively this shows the audence the insane levels of trust citizens have in their Nanny Program, but for the real world let’s just say it’s best that you don’t require police to submit to a Flash Gordon Wood Beast just to hand over exhibit A.

There’s a nice touch to the transparent walls allowing him to see the computer screen through it, to get the visual confirmation of what he’s hearing. But I suspect the curved surface also adds a bit of distortion to his view that doesn’t help readability. So the industrial design aspects of the interface sort of even out. Unless I’m missing something. Any industrial designers want to weigh in?

A final objection is the unnecessarily vast architecture that is part of the workflow. Why this giant room with a thin cylinder in the middle of it? Sure there are narrative reasons for it (welcome to this digital heart of darkness) but it seems like something that Sandmen would be doing routinely, and this giant ritual just makes a creepy, big deal about it.

Better

Better might be a wide, waist-high cubby off to the side of their offices, whatever those are, with a wide tray and computer screen. Sandmen could drop the evidence into the tray and place their hands into an authenticator outside the tray, initiating the scan. This would save them the awkward time of waiting for the computer to order them to authenticate, and tightly couple the objects with their identity. The improved semiotics say, “I, Logan, found these and am surrendering them to you.” Then if the computer needed to speak more about it, it could summon them to an interlocution room, or something with a similarly awkward 70s name.

The SandPhone

5 Nov 2013 by Christopher Noessel

Not everyone is comfortable giving over to the flimsy promise of Carrousel [sic]. Some citizens run, and Sandmen find and terminate these cultural heretics.

Sandmen carry a device with them that has many different uses. It goes unnamed in the movie, so let’s just call it the SandPhone. It is a thick black rectangle about 20cm at its long edge, about the size of a very large cell phone. Near the earpiece on one broad side is a small screen for displaying text and images. Below that is a white line. The lower half of this face is metallic grill that covers a microphone. On the left edge is a momentary button that allows talking. Just above this is a small red button. When not in use, the device is holstered on the sandman’s belt.

The SandPhone lets the Sandman receive information through a display that can show both image and text. The Sandman sends back information and requests by voice in a CB radio metaphor.

Notifications

The first time we see the device is when Logan and Francis are attending Carrousel. Somehow, on his belt it catches his attention. With the crowd too loud for sound, and no evidence it’s light, my bet’s on haptics. Realizing he’s got a message, he picks it up, presses the edge button and the screen displays two lines of text:

RUNNER: GREAT HALL
ENTRANCE WEST.

He then puts the device to his face as we would a cell phone and shouts, “Affirmative!” as loud as he can.

Perp wayfinding

Running with the device outside the Great Hall, Logan uses the SandPhone as a detector. By holding it flat out in front of him he hears a rhythmic pulse. Turning it this way and that, he listens for the change in pitch. It rises when he is pointing towards the targeted runner.

Bio identification

When he and Francis have terminated the runner, he snaps the device off his belt, and pressing the edge button, he reports back to dispatch, “Runner terminated, 0.31. Ready for cleanup.” Then by placing the device near the head of the dead runner, the device displays on the screen the last photographic image of him on file. Since the face on the SandPhone screen does not match the face he sees before him, Logan lifts the device to his face and, holding the edge button, requests an identity check of dispatch. Instantly he pulls the device away from his face to show the text:

IDENT. AFFIRM
NEW YOU #483
FACE CHANGE.

Send backup

Much later in the film we see Logan alert dispatch to the location of the underground hideout by reaching down to the holstered device and pressing the white line button on its face. Its screen pulses green, and his position is highlight on the runner board (see below) at dispatch. Minutes later the location is raided by Sandmen.

Analysis

The first thing to note is that this is pretty close to a modern smart phone. He receives images and text messages, can talk to dispatch, and it has a biometric capability for identifying citizens. It’s tempting to paint this as visionary, but keep in mind that the first mobile phone was demonstrated in 1973, three years earlier, so it’s likely that the film makers were riffing off of the demo technology they’d heard about or maybe even seen in person.

We evaluate an interface’s design by how well it helps its user achieves his goals. (Even if those goals are anethma. That’s how we judge an interface.) In this case, the SandPhone helps Logan get the information he needs, when he needs it, across multiple channels. It doesn’t distract him with other functions. It’s context aware and doesn’t apparently have battery issues.

There are improvements of course.

We should make sure his hands are free by making the information available as an augmented reality display instead of a handheld device. This would also give him the information privately rather than display it for anyone (notably members of the resistance) to see it. Wayfinding would be more sensible as an overlay to his vision through this device.

Some surface tweaks might also be made, such as giving him a means of text input so he wouldn’t have to shout above the roar of Carrousel. Some silent means of input would help for when he needs to provide silent input as well. First I thought optical inputs might be ideal, given the augmented reality, but we don’t want his eyes distracted like that, even for the duration of glances. Instead some other gestural input—perhaps a face twitch or subvocal input—that lets him keep the rest of his body tense and ready for action.

Citizen biometrics should be a background fact, given the penopticon of Dome City. The information would come to him when he gets his assignement. But turn those same biometrics around on Logan, and his body could request reinforcements before he even thought to do so manually. When his heart rate elevates and galvanic skin response lowers, dispatch would know something was up, and route backup immediately.

A strategic interaction designer would even ask why he has to chase runners at all, when predictive algorithms could guess which citizens were likely to run and take action to forestall their rebellion. But then we’re into Minority Report, and this needs to stay Logan’s Run.

Lifeclock: The central conceit

25 Sep 2013 by Christopher Noessel

The central technological conceit of the movie is the lifeclock, a rosette crystal that is implanted in each citizens left palm at birth. This clock changes color in stages over the course of the individuals lifetime.

Though the information in the movie is somewhat contradictory as to the actual stages, the DVD has an easter egg that explains the stages as follows.

White		Birth to 8 years
Yellow		9 to 15 years
Green		16 to 23 years
Red		24 years to 10 days before Lastday (30 years)
Blinking Red		from 10 days before Lastday to Lastday
Black		End of Lastday (Carousel/death)

Lifeclocks derive their signal and possibly power from a local-area broadcast in the city. When Logan and Jessica leave the city their lifeclocks turn clear.

The signal of the lifeclock is so central to life that most citizens dress exclusively in colors that match their lifeclock color. Only certain professions, such as Sandmen and the New You doctor, are seen to wear clothing that lacks clear reference to a lifeclock color, even though the individuals in these professions have lifeclocks and are still subject to carousel at Lastday. We can presume, though are not shown explicitly, that certain rights and responsibilities are conferred on citizens in different stages, such as legal age of sexual consent and access to intoxicants, so the clothing acts as a social signal of status.

As an interface the lifeclock is largely passive, and can be discussed for its usability in two main ways.

Color

The first is the color. Are the stages easily discernable by people? The main problem would be between the red and green stages since the forms of red-green color blindness affects around 4% of the population. To accommodate for this, reds are made more discernable with a brighter glow than the green. As a wavelength, red carries the farthest, and blinking is of course a highly visible and attention-getting signal, which makes it difficult for an individual to socially hide that his or her time for carousel has come.

Black is a questionable signal since this indicates actual violation of the law but does not draw any attention to itself. Casual observation of a relaxed hand with a black lifeclock might even be mistaken for a colored lifeclock in shadow, but as the citizenry has complete faith in the system and a number of countermeasures in place to ensure that everyone either attends carousel or is terminated, perhaps this is not a concern.

But if we’re just going on human signal processing, the red should be reserved for LastWeek, and a blinking red for after LastDay. That leaves a color gap between 24 and 30. I’d make this phase blue, since it looks so clearly different from red. The new colors would be as follows.

White		Birth to 8 years
Yellow		9 to 15 years
Green		16 to 23 years
Blue		24 years to 10 days before Lastday (30 years)
Red		from 10 days before Lastday to Lastday
Blinking Red		End of Lastday (Carousel/death)

Location on the body

The second question is the location of the lifeclock. Where should it be placed? It is a social signal, and as such needs to be visible. The parts of the body that are most often seen uncovered in the film are the hand, the neck, and the head. The neck and head are problematic since these are not visible to the citizen himself, useful for reinforcing compliance with the system. This leaves the hand.

Given the hand, the palm seems an odd choice since in a relaxed position or when the hand is in use, the palm is often hidden from view of other people. The colored clothing seen in the film show that a citizens life stage is not really considered a private matter, so a location on the back of the hand would have made more sense. To keep it in view of its owner, a location on the fleshy pad between the thumb and the forefinger would have made a better, if less cinematic, choice.

Portable brainwave detector

28 Feb 2013 by Christopher Noessel

Through the atom transmitter Dianthus bestows several gifts on Barbarella to help her with her mission. The first of these is the “portable brainwave detector…to test for Durand-Durand’s presence.” To operate it, Barbarella must press “a contact,” (Dianthus is offscreen when he indicates the contact, but later we see her operating the leaf-like button near the wrist) and if Durand-Durand is around, the ball of lights will glow and an alarm will sound.

The device is wearable, wrapping around Barbarella’s forearm, and held in place by a ring. This aspect of the design is good, since it means the device is ever-present for operation, and the design of it makes it lovely enough to be overlooked as a fashion accessory. In fact many characters see her wearing it and make no mention.

Manual activation is less than ideal, though, since this might tip off the suspect. This is especially true with the blinking, glowing ball of light and audio feedback. And, in fact, this is what happens later in the film when Durand-Durand trips over the device. The blinking light and audio catch his attention, betray the device for what it is, and blow Barbarella’s cover in the process.

Portable Brainwave Device

The best feedback would be invisible, like a haptic vibration through the cuff to her skin. Ideally, the device would be constantly on, to detect the subject passively, the moment he came into range. But presuming battery life is the issue, the activation cue should be something much more subtle, like Barbarella’s touching the back of the ring with the thumb of the same hand. Such a gesture would match the existing design of the object, be discreet to an observer, and yet still discrete enough to prevent accidental activation.

Remote Monitoring

27 Dec 2012 by Christopher Noessel

The Prometheus spacesuits feature an outward-facing camera on the chest, which broadcasts its feed back to the ship, where the video it overlaid with the current wearer’s name, and inscrutable iconographic and numerical data along the periphery. The suit also has biometric sensors, continuously sending it’s wearer’s vital signs back to the ship. On the monitoring screen, a waveform in the lower left appears is similar to a EKG, but is far too smooth and regular to be an actual one. It is more like an EKG icon. We only see it change shape or position along its bounding box once, to register that Weyland has died, when it turns to a flat line. This supports its being iconic rather than literal.

In addition to the iconic EKG, a red selection rectangle regularly changes across a list in the upper left hand corner of the monitor screens. One of three cyan numbers near the top occasionally changes. Otherwise the peripheral data on these monitoring screens does not change throughout the movie, making it difficult to evaluate its suitability.

The monitoring panel on Prometheus features five of the monitoring feeds gathered on a single translucent screen. One of these feeds has the main focus, being placed in the center and scaled to double the size of the other monitors. How the monitoring crewperson selects which feed to act as the main focus is not apparent.

Vickers has a large, curved, wall-sized display on which she’s able to view David’s feed at one point, so these video feeds can be piped to anyone with authority.

David is able to turn off the suit camera at one point, which Vickers back on the Prometheus is unable to override. This does not make sense for a standard-issue suit supplied by Weyland, but it is conceivable that David has a special suit or has modified the one provided to him during transit to LV-223.

Security and Control’s control

30 Oct 2012 by Christopher Noessel

The mission is world-critical, so like a cockpit, the two who are ultimately in control are kept secure. The control room is accessible (to mere humans, anyway) only through a vault door with an armed guard. Hadley and Sitterson must present IDs to the guard before he grants them access.

Sitterson and Hadley pass security.

Truman, the guard, takes and swipes their cards through a groove in a hand-held device. We are not shown what is on the tiny screen, but we do hear the device’s quick chirps to confirm the positive identity. That sound means that Truman’s eyes aren’t tied to the screen. He can listen for confirmation and monitor the people in front of him for any sign of nervousness or subterfuge.

Hadley boots up the control room screens.

The room itself tells a rich story through its interfaces alone. The wooden panels at the back access Bronze Age technology with its wooden-handled gears, glass bowls, and mechanical devices that smash vials of blood. The massive panel at which they sit is full of Space Age pushbuttons, rheostats, and levers. On the walls behind them are banks of CRT screens. These are augmented with Digital Age, massive, flat panel displays and touch panel screens within easy reach on the console. This is a system that has grown and evolved for eons, with layers of technology that add up to a tangled but functional means of surveillance and control.

The interfaces hint at the great age of the operation.

Utter surveillance

In order for Control to do their job, they have to keep tabs on the victims at all times, even long before the event: Are the sacrifices conforming to archetype? Do they have a reason to head to the cabin?

The nest empties.

To these ends, there are field agents in the world reporting back by earpiece, and everything about the cabin is wired for video and audio: The rooms, the surrounding woods, even the nearby lake.

Once the ritual sacrifice begins, they have to keep an even tighter surveillance: Are they behaving according to trope? Do they realize the dark truth? Is the Virgin suffering but safe? A lot of the technology seen in the control room is dedicated to this core function of monitoring.

The stage managers monitor the victims.

There are huge screens at the front of the room. There are manual controls for these screens on the big panel. There is an array of CRTs on the far right.

The small digital screens can display anything, but a mode we often see is a split in quarters, showing four cameras in the area of the stage. For example, all the cameras fixed on the rooms are on one screen. This provides a very useful peripheral signal in Sitterson and Hadley’s visual field. As they monitor the scenario, motion will catch their eyes. If that motion is not on a monitor they expect it to be, they can check what’s happening quickly by turning their head and fixating. This helps keep them tightly attuned to what’s happening in the different areas on “stage.”

For internal security, the entire complex is also wired for video, including the holding cages for the nightmare monsters.

Sitterson looks for the escapees amongst the cubes.

The control room watches the bloody chaos spread.

One screen that kind of confuses us appears to be biometrics of the victims. Are the victims implanted with devices for measuring such things, or are sophisticated non-invasive environmental sensors involved? Regardless of the mechanisms, if Control has access to vital signs, how are they mistaken about Marty’s death? We only get a short glance at the screen, so maybe it’s not vital signs, but simple, static biometrics like height, and weight, even though the radiograph diagram suggests more.

Sitterson tries to avoid talking to Mordecai.

Communications

Sitterson and Hadley are managing a huge production. It involves departments as broad ranging as chemistry, maintenance, and demolitions. To coordinate and troubleshoot during the ritual, two other communications options are available beyond the monitors; land phone lines and direct-connection, push-to-talk microphones.
