A special subset of spacesuit interfaces is the communication subsystems. I wrote a whole chapter about Communications in Make It So, but spacesuit comms bear special mention, since they’re usually used in close physical proximity but still must be mediated by technology, the channels for detailed control are clumsy and packed, and these communicators are often being overseen by a mission control center of some sort. You’d think this is rich territory, but spoiler: There’s not a lot of variation to study.
Every single spacesuit in the survey has audio. This is so ubiquitous and accepted that, after 1950, no filmmaker has thought the need to explain it or show an interface for it. So you’d think that we’d see a lot of interactions.
Spacesuit communications in sci-fi tend to be many-to-many with no apparent means of control. Not even a push-to-mute if you sneezed into your mic. It’s as if the spacewalkers were in a group, merely standing near each other in air, chatting. No push-to-talk or volume control is seen. Communication with Mission Control is automatic. No audio cues are given to indicate distance, direction, or source of the sound, or to select a subset of recipients.
The one seeming exception to the many-to-many communication is seen in the reboot of Battlestar Galactica. As Boomer is operating a ship above a ground crew, shining a light down on them for visibility, she has the following conversation with Tyrol.
Raptor 478, this is DC-1, I have you in my sights.
Copy that, DC-1. I have you in sight.
How’s it looking there? Can you tell what happened?
Lieutenant, don’t worry…about my team. I got things under control.
Copy that, DC-1. I feel better knowing you’re on it.
Then, when her copilot gives her a look about what she has just said, she says curtly to him, “Watch the light, you’re off target.” In this exchange there is clear evidence that the copilot has heard the first conversation, but it appears that her comment to him is addressed to him and not for the others to hear. Additionally, we do not hear chatter going on between the ground grew during this exchange. Unfortunately, we do not see any of the conversationalists touch a control to give us an idea about how they switch between these modes. So, you know, still nothing.
More recent films, especially in the MCU, has seen all sorts of communication controlled by voice with the magic of General AI…pause for gif…
…but as I mention more and more, once you have a General AI in the picture, we leave the realm of critique-able interactions. Because an AI did it.
In short, sci-fi just doesn’t care about showing audio controls in sci-fi spacesuits, and isn’t likely to start caring anytime soon. As always, if you know of something outside my survey, please mention it.
For reference, in the real world, a NASA astronaut has direct control over the volume of audio that she hears, using potentiometer volume controls. (Curiously the numbers on them are not backwards, unlike the rest of the controls.)
A spacewalker uses the COMM dial switch mode selector at the top of the DCM to select between three different frequencies of wireless communication, each of which broadcasts to each other and the vehicle. When an astronaut is on one of the first two channels, transmission is voice-activated. But a backup, “party line” channel requires push-to-talk, and this is what the push-to-talk control is for.
By default, all audio is broadcast to all other spacewalkers, the vehicle, and Mission Control. To speak privately, without Mission Control hearing, spacewalkers don’t have an engineered option. But if one of the radio frequency bands happens to be suffering a loss of signal to Mission Control, she can use this technological blind spot to talk with some degree of privacy.
So the first Fritzes are now a thing. Before I went off on that awesome tangent, where were we? Oh that’s right. I was reviewing Blade Runner as part of a series on AI in sci-fi. I was just about to get to Spinners. Now vehicles are complicated things as they are, much less when they are navigating proper 3D space. Additionally, the police force is, ostensibly, a public service, which complicates things even further. So this will get lengthy. Still, I think I can get this down to eight or so subtopics.
In the distant future of 2019⸮, flying cars, called “spinners,” are a reality. They’re largely for the wealthy and powerful (including law enforcement). The main protagonist, Deckard, is only ever a passenger in a few over the course of the film. His partner Gaff flies one, though, so we have enough usage to review.
To pilot the spinner, Gaff keeps his hands on each handle of a split yoke. Within easy reach of his fingers are a few unlabeled buttons and small lights. Once we see him reach with his right thumb to press one of the buttons, but we don’t see any result, so it’s not clear what these buttons do. It’s nice that they don’t require him to take his hands off the controls. (This might seem like a prescient concept, but WP tells me the first non-horn wheel-mounted controls date back as far back as 1966.)
It is contextualizing to note the mode of agency here. That is, the controls are manual, with no AI offering assistance or acting as an agent. (The AI is in the passenger’s seat, lol fight me.) It appears to be up to Gaff to observe conditions, monitor displays, perform wayfinding, and keep the spinner on track.
Note that we never see what his feet are doing and never see him doing other things with his hands other than putting on a headset before lift-off. There are lots of other controls to the pilot’s left and in the console between seats, but we never see them in use. So, you know, approach with caution. There are a lot of unknowns here.
The spinner is more like a VTOL aircraft or helicopter than a spaceship. That is, it is constantly in the presence of planetary gravity and must overcome the constant resistance of air. So the standards I established in the piloting controls post are of only limited use to us here.
The vertical velocity, up or down. (Controlled by the angle of the control stick called the collective. The collective is to the left of the pilot’s hip when they are seated.)
The thrust. (Controlled by the twistgrip on the collective.)
Movement forward, rearward, left, and right. (Controlled with the stick in front of the pilot, called the cyclic.)
Yaw of the vehicle. (Controlled with the pair of antitorque pedals at the pilot’s feet.)
Since we don’t see Gaff when the spinner is moving up and down, let’s presume that the thing he’s gripping is like a Y-shaped cyclic, with lots of little additional controls around the handles. Then, if we presume he has a collective somewhere out of sight to his left and antitorque pedals at his feet, this interface meets modern helicopter standards for control. From the outside, those appear to be well mapped (collective up = helicopter up, cyclic right = helicopter right). Twist for thrust is a little weird, but it’s a standard and certainly learnable, as I recall from my motorcycling days. So let’s say it’s complete and convincing. Is it the best it could be? I’m not enough of an aeronautical engineer (read: not at all) to imagine better options, so let’s move along. I might have more to say if it was agentive.
There are two large screens in the dashboard. The one directly in front of Gaff shows a stylized depiction of the 3D surfaces around him as cyan highlights on a navy blue background. Approaching red shapes describe a pill-shaped tunnel-in-the-sky display. These have been tested since 1981 and found to provide higher tracking performance to ideal paths in manual flight, lower cognitive workload, and enhanced situational awareness. (https://arc.aiaa.org/doi/abs/10.2514/3.56119) So, this is believable and well done. I’m not sure that Gaff could readily use the 3D background to effectively understand the 3D terrain, but it is tertiary, after the real world and the tunnel display.
I have to say that it’s a frustrating anti-trope to run into again, but it must be said: If the spinner knows where the ship should be, and general artificial intelligence exists in this diegesis, why exactly are humans doing the piloting? Shouldn’t the spinner fly itself? But back to the interfaces…
Above the tunnel-in-the-sky display is a cyan 7-segment LED scroll display. In the gif above it displays “MAXIMUM SPEED” and later it provides some wayfinding text. I’m not sure how many different types of information it is meant to cycle through, but it sure would be a pain to wait for vital information to appear, and distracting to have to control it to get to the one you wanted.
There is also a vertical screen in the middle of the console listing cyan labels ALT, VEL, and PTCH. These match to altitude, velocity, and pitch variables, reinforcing the helicopter model. The yellow numbers below these labels change in the scene very slowly, and—remarkably for a four-second interface from 1982—do not appear to change randomly. That’s awesome.
But then, there’s a paragraph of cyan text in the middle of the screen that appears over the course of the scene, letter by letter. This animation calls unnecessary attention to itself. There are also smaller, thin screens in the pilot’s door that also continually scroll that same teeny tiny cyan text. I’m not sure WTF all this text is supposed to be, since it would be horribly distracting to a pilot. There are also a few rows of white LEDs with cylon-eye displays traveling back and forth. They are distracting, but at least they’re regular, and might be habituate-able and act as some sort of ambient display. Anyway, if we were building this thing for real, we’d want to eliminate these.
Lastly, at the bottom of the center screen are some unlabeled bar charts depicting some variables that appear to be wiggling randomly. So, like, only the top fifth of this screen can be lauded. The rest is fuigetry. *sigh* It’s hard to escape.
To help navigate the 3D space, pilots have a number of tools. First, there are windows where you expect windows to be in a car, and there are also glass panels under their feet. The movie doesn’t make a big deal out of it, but it’s clear in the scene where the spinner lifts off from the street level. These transparent panes surround pilots and passengers and allow them to track visual cues for landmarks and to identify collision threats.
The tunnel-in-the-sky display above is the most obvious wayfinding tool. Somehow Gaff has entered a destination, and the tunnel guides him where it needs to go. Since this entails a safe path through the air, it’s the most important display. Other bits of information (like the ALT, VEL, and PTCH in the center screen) should be oriented around it. This would make them glanceable, allowing Gaff glance to check them and quickly return his eyes to the windshield. In fact, we have to admit that a heads up display would allow Gaff to keep his attention where it needs to be rather than splitting it between the real world and these dashboard displays. Modern vehicle drivers are used to this split attention, and can manage it well enough. But I suspect that a HUD would be better.
There is also that crawling LED display above the tunnel-in-the-sky screen. In one scene it shows “SECTOR FOUR (4)…QUAD-” (we don’t get to see the end of this phrase) but it implies that one of the bits of information this scroll provides is a reminder of the name of the neighborhood you’re currently in. That really only helps if you’re way off course, and seems too low a fidelity for actual wayfinding assistance, but presuming the tunnel-in-the-sky is helping provide the rest of the wayfinding, this information is of secondary importance.
A special note about takeoff: ENVIRON CTR
The display sequence infamous for appearing in both Alien and Blade Runner happens as Gaff lifts off in a spinner early in the film. White all-cap letters label this blue screen “ENVIRON CTR,” above a grid of square characters. Then two 8-digit sequences “drop” down the center of the square grid: 92886599 | 95654085. Once they drop 3 rows, the background turns red, the grid disappears to be replaced by a big blinking label PURGE. Characters at the bottom read “24556 DR 5”, and don’t change.
After the spinner lifts off the display shows a complex diagram of a circle-within-a-circle, illustrating the increasing elevation from the ground below. The delightful worldbuilding thing about the sequence is that it is inscrutable, and legible only by a trained driver, yet gets full focus on screen. There’s not really enough information about the speculative engineering or functional constraints of the spinner to say why these screens would be necessary or useful. I have a suspicion that a live camera view would be more useful than the circle-within-a-circle view, but gosh, it sure is cool. Here’s the shot from Alien, by the way, for easy comparison.
Of special note is a scene just before his call to Sebastian’s apartment. Deckard is sitting in his parked vehicle in a call with Bryant. A police spinner glides by and we hear an announcement over his loudspeaker, directed to Deckard’s vehicle saying, “This sector’s closed to ground traffic. What are you doing here?” From inside his vehicle, Deckard looks towards his video phone in the console (we never see if there is video, but he’s looking in that direction rather than out the window) and without touching a thing, responds defensively, “I’m working. What are you doing?” The policeman’s reply comes through the videophone’s speakers, “Arresting you, that’s what I’m doing.”
Note that Deckard did not have to answer the call or even put Bryant on hold. We don’t know what the police officer did on their end, but this interaction implies that the police can make an instant, intrusive audio connection with vehicles it finds suspicious. It’s so seamless it will slip by you if you don’t know to look for it, but it paints quite a picture of intercar communication. Can you imagine if our cars automatically shared an audio space with the cars around it?
Another aspect of the car is that it is an interface not just for the people using the car, but for the citizens observing or near the spinner as it goes about its business. There are a number of features that helps it act as an interface to the public.
Police exist as a social service, and the 995 repeated around the outside helps remind citizens of the number they can call in case of an emergency.
Modern patrol cars have beacons and sirens to tell other drivers to get out of the way when they are on urgent business. Police spinners are gravid with beacons, having 12 of them visible from the front alone. (See below.) As the spinner is taking off, yellow and blue beacons circle as a warning. This would be of no help to a blind person nearby, but the vehicle does make some incidental noise that serves as an audible warning.
The rich light strip makes sense because it has such a greater range of movement than ground-based cars, and needs more attention grabbing power. Another nice touch is that, since the spinner can be above people, there are also beacons on the chassis.
Upshot: Spinners do well
So, all in all, the spinner fares quite well on close inspection. It builds on known models of piloting, shows mostly-relevant data, uses known best practices for assistance, and has a lot of well-considered surface features for citizens.
Now if only I could figure out why they’re called spinners.
As soon as the Black Queen hears of Durand-Durand’s betrayal, she reveals a panel that is hidden by furs. It is vertical with a handful of transparent, organically-shaped knobs. She clicks the top one out of its off position and rotates it back and forth a few times, and the panel begins to glow as a video image appears on the high walls of the chamber, showing the events happening inside the throne room.
Later the Queen turns the top knob counterclockwise to click it back into its stop position to stop the video feed. Then she turns another one the same direction to reveal a different video feed of the labyrinth, indicating that each knob is connected to a particular view. There’s indirect evidence that the degree of rotation controls the volume of audio.
Typically remotes have separate controls for power, channel selection, and volume. Coupling them like this adds extra work to the task of switching channels. The Dark Queen has to turn one off before turning the next one on, and readjust the volume each time. If switching channels is something she does regularly, that’s going to be a pain. But if the large screen can display more than one video feed at a time, automatically diving the screen real estate equally to accomodate the multiple views, these controls make a lot of sense, even allowing her to set the volume per feed to a sensible level.
The only thing that might improve the interface is some label to know which control displays which video feed. Seeing as how they’re translucent, I’d suggest coating them with a rear projection film and piping the video feed directly onto the button from beneath. That provides a direct mapping from the control to the display, and a glanceable preview to let the Dark Queen what might be interesting to watch in the first place.
