Disclosure (1994)

Our next 3D file browsing system is from the 1994 film Disclosure. Thanks to site reader Patrick H Lauke for the suggestion.

Like Jurassic Park, Disclosure is based on a Michael Crichton novel, although this time without any dinosaurs. (Would-be scriptwriters should compare the relative success of these two films when planning a study program.) The plot of the film is corporate infighting within Digicom, manufacturer of high tech CD-ROM drives—it was the 1990s—and also virtual reality systems. Tom Sanders, executive in charge of the CD-ROM production line, is being set up to take the blame for manufacturing failures that are really the fault of cost-cutting measures by rival executive Meredith Johnson.

The Corridor: Hardware Interface

The virtual reality system is introduced at about 40 minutes, using the narrative device of a product demonstration within the company to explain to the attendees what it does. The scene is nicely done, conveying all the important points we need to know in two minutes. (To be clear, some of the images used here come from a later scene in the film, but it’s the same system in both.)

The process of entangling yourself with the necessary hardware and software is quite distinct from interacting with the VR itself, so let’s discuss these separately, starting with the physical interface.

In Disclosure the virtual reality user wears a headset and one glove, all connected by cables to the computer system. Like most virtual reality systems, the headset is responsible for visual display, audio, and head movement tracking; the glove for hand movement and gesture tracking. 

There are two “laser scanners” on the walls. These are the planar blue lights, which scan the user’s body at startup. After that they track body motion, although since the user still has to wear a glove, the scanners presumably just track approximate body movement and orientation without fine detail.

Lastly, the user stands on a concave hexagonal plate covered in embedded white balls, which allows the user to “walk” on the spot.

Searching for Evidence

The scene we’re most interested in takes place later in the film, the evening before a vital presentation which will determine Tom’s future. He needs to search the company computer files for evidence against Meredith, but discovers that his normal account has been blocked from access.   He knows though that the virtual reality demonstrator is on display in a nearby hotel suite, and also knows about the demonstrator having unlimited access. He sneaks into the hotel suite to use The Corridor. Tom is under a certain amount of time pressure because a couple of company VIPs and their guests are downstairs in the hotel and might return at any time.

The first step for Tom is to launch the virtual reality system. This is done from an Indy workstation, using the regular Unix command line.

Next he moves over to the VR space itself. He puts on the glove but not the headset, presses a key on the keyboard (of the VR computer, not the workstation), and stands still for a moment while he is scanned from top to bottom.

On the left is the Indy workstation used to start the VR system. In the middle is the external monitor which will, in a moment, show the third person view of the VR user as seen earlier during the product demonstration.

Now that Tom has been scanned into the system, he puts on the headset and enters the virtual space.

The Corridor: Virtual Interface

“The Corridor,” as you’ve no doubt guessed, is a three dimensional file browsing program. It is so named because the user will walk down a corridor in a virtual building, the walls lined with “file cabinets” containing the actual computer files.

Three important aspects of The Corridor were mentioned during the product demonstration earlier in the film. They’ll help structure our tour of this interface, so let’s review them now, as they all come up in our discussion of the interfaces.

  1. There is a voice-activated help system, which will summon a virtual “Angel” assistant.
  2. Since the computers themselves are part of a multi-user network with shared storage, there can be more than one user “inside” The Corridor at a time.
    Users who do not have access to the virtual reality system will appear as wireframe body shapes with a 2D photo where the head should be.
  3. There are no access controls and so the virtual reality user, despite being a guest or demo account, has unlimited access to all the company files. This is spectacularly bad design, but necessary for the plot.

With those bits of system exposition complete, now we can switch to Tom’s own first person view of the virtual reality environment.

Virtual world Tom watches his hands rezzing up, right hand with glove. Disclosure (1994)

There isn’t a real background yet, just abstract streaks. The avatar hands are rezzing up, and note that the right hand wearing the glove has a different appearance to the left. This mimics the real world, so eases the transition for the user.

Overlaid on the virtual reality view is a Digicom label at the bottom and four corner brackets which are never explained, although they do resemble those used in cameras to indicate the preferred viewing area.

To the left is a small axis indicator, the three green lines labeled X, Y, and Z. These show up in many 3D applications because, silly though it sounds, it is easy in a 3D computer environment to lose track of directions or even which way is up. A common fix for the user being unable to see anything is just to turn 180 degrees around.

We then switch to a third person view of Tom’s avatar in the virtual world.

Tom is fully rezzed up, within cloud of visual static. Disclosure (1994)

This is an almost photographic-quality image. To remind the viewers that this is in the virtual world rather than real, the avatar follows the visual convention described in chapter 4 of Make It So for volumetric projections, with scan lines and occasional flickers. An interesting choice is that the avatar also wears a “headset”, but it is translucent so we can see the face.

Now that he’s in the virtual reality, Tom has one more action needed to enter The Corridor. He pushes a big button floating before him in space.

Tom presses one button on a floating control panel. Disclosure (1994)

This seems unnecessary, but we can assume that in the future of this platform, there will be more programs to choose from.

The Corridor rezzes up, the streaks assembling into wireframe components which then slide together as the surfaces are shaded. Tom doesn’t have to wait for the process to complete before he starts walking, which suggests that this is a Level Of Detail (LOD) implementation where parts of the building are not rendered in detail until the user is close enough for it to be worth doing.

Tom enters The Corridor. Nearby floor and walls are fully rendered, the more distant section is not complete. Disclosure (1994)

The architecture is classical, rendered with the slightly artificial-looking computer shading that is common in 3D computer environments because it needs much less computation than trying for full photorealism.

Instead of a corridor this is an entire multistory building. It is large and empty, and as Tom is walking bits of architecture reshape themselves, rather like the interior of Hogwarts in Harry Potter.

Although there are paintings on some of the walls, there aren’t any signs, labels, or even room numbers. Tom has to wander around looking for the files, at one point nearly “falling” off the edge of the floor down an internal air well. Finally he steps into one archway room entrance and file cabinets appear in the walls.

Tom enters a room full of cabinets. Disclosure (1994)

Unlike the classical architecture around him, these cabinets are very modern looking with glowing blue light lines. Tom has found what he is looking for, so now begins to manipulate files rather than browsing.

Virtual Filing Cabinets

The four nearest cabinets according to the titles above are

  1. Communications
  2. Operations
  3. System Control
  4. Research Data.

There are ten file drawers in each. The drawers are unmarked, but labels only appear when the user looks directly at it, so Tom has to move his head to centre each drawer in turn to find the one he wants.

Tom looks at one particular drawer to make the title appear. Disclosure (1994)

The fourth drawer Tom looks at is labeled “Malaysia”. He touches it with the gloved hand and it slides out from the wall.

Tom withdraws his hand as the drawer slides open. Disclosure (1994)

Inside are five “folders” which, again, are opened by touching. The folder slides up, and then three sheets, each looking like a printed document, slide up and fan out.

Note the tilted axis indicator at the left. The Y axis, representing a line extending upwards from the top of Tom’s head, is now leaning towards the horizontal because Tom is looking down at the file drawer. In the shot below, both the folder and then the individual documents are moving up so Tom’s gaze is now back to more or less level.

At this point the film cuts away from Tom. Rival executive Meredith, having been foiled in her first attempt at discrediting Tom, has decided to cover her tracks by deleting all the incriminating files. Meredith enters her office and logs on to her Indy workstation. She is using a Command Line Interface (CLI) shell, not the standard SGI Unix shell but a custom Digicom program that also has a graphical menu. (Since it isn’t three dimensional it isn’t interesting enough to show here.)

Tom uses the gloved hand to push the sheets one by one to the side after scanning the content.

Quick note: This is harder than it looks in virtual reality. In a 2D GUI moving the mouse over an interface element is obvious. In three dimensions the user also has to move their hand forwards or backwards to get their hand (or finger) in the right place, and unless there is some kind of haptic feedback it isn’t obvious to the user that they’ve made contact.

Tom now receives a nasty surprise.

The shot below shows Tom’s photorealistic avatar at the left, standing in front of the open file cabinet. The green shape on the right is the avatar of Meredith who is logged in to a regular workstation. Without the laser scanners and cameras her avatar is a generic wireframe female humanoid with a face photograph stuck on top. This is excellent design, making The Corridor usable across a range of different hardware capabilities.

Tom sees the Meredith avatar appear. Disclosure (1994)

Why does The Corridor system place her avatar here? A multiuser computer system, or even just a networked file server,  obviously has to know who is logged on. Unix systems in general and command line shells also track which directory the user is “in”, the current working directory. Meredith is using her CLI interface to delete files in a particular directory so The Corridor can position her avatar in the corresponding virtual reality location. Or rather, the avatar glides into position rather than suddenly popping into existence: Tom is only surprised because the documents blocked his virtual view.

Quick note: While this is plausible, there are technical complications. Command line users often open more than one shell at a time in different directories. In such a case, what would The Corridor do? Duplicate the wireframe avatar in each location? In the real world we can’t be in more than one place at a time, would doing so contradict the virtual reality metaphor?

There is an asymmetry here in that Tom knows Meredith is “in the system” but not vice versa. Meredith could in theory use CLI commands to find out who else is logged on and whether anyone was running The Corridor, but she would need to actively seek out that information and has no reason to do so. It didn’t occur to Tom either, but he doesn’t need to think about it,  the virtual reality environment conveys more information about the system by default.

We briefly cut away to Meredith confirming her CLI delete command. Tom sees this as the file drawer lid emitting beams of light which rotate down. These beams first erase the floating sheets, then the folders in the drawer. The drawer itself now has a red “DELETED” label and slides back into the wall.

Tom steps further into the room. The same red labels appear on the other file drawers even though they are currently closed.

Talking to an Angel

Tom now switches to using the system voice interface, saying “Angel I need help” to bring up the virtual reality assistant. Like everything else we’ve seen in this VR system the “angel” rezzes up from a point cloud, although much more quickly than the architecture: people who need help tend to be more impatient and less interested in pausing to admire special effects.

The voice assistant as it appears within VR. Disclosure (1994)

Just in case the user is now looking in the wrong direction the angel also announces “Help is here” in a very natural sounding voice.

The angel is rendered with white robe, halo, harp, and rapidly beating wings. This is horribly clichéd, but a help system needs to be reassuring in appearance as well as function. An angel appearing as a winged flying serpent or wheel of fire would be more original and authentic (yes, really: ​​Biblically Accurate Angels) but users fleeing in terror would seriously impact the customer satisfaction scores.

Now Tom has a short but interesting conversation with the angel, beginning with a question:

  • Tom
  • Is there any way to stop these files from being deleted?
  • Angel
  • I’m sorry, you are not level five.
  • Tom
  • Angel, you’re supposed to protect the files!
  • Angel
  • Access control is restricted to level five.

Tom has made the mistake, as described in chapter 9 Anthropomorphism of the book, of ascribing more agency to this software program than it actually has. He thinks he is engaged in a conversational interface (chapter 6 Sonic Interfaces) with a fully autonomous system, which should therefore be interested in and care about the wellbeing of the entire system. Which it doesn’t, because this is just a limited-command voice interface to a guide.

Even though this is obviously scripted, rather than a genuine error I think this raises an interesting question for real world interface designers: do users expect that an interface with higher visual quality/fidelity will be more realistic in other aspects as well? If a voice interface assistant has a simple polyhedron with no attempt at photorealism (say, like Bit in Tron) or with zoomorphism (say, like the search bear in Until the End of the World) will users adjust their expectations for speech recognition downwards? I’m not aware of any research that might answer this question. Readers?

Despite Tom’s frustration, the angel has given an excellent answer – for a guide. A very simple help program would have recited the command(s) that could be used to protect files against deletion. Which would have frustrated Tom even more when he tried to use one and got some kind of permission denied error. This program has checked whether the user can actually use commands before responding.

This does contradict the earlier VR demonstration where we were told that the user had unlimited access. I would explain this as being “unlimited read access, not write”, but the presenter didn’t think it worthwhile to go into such detail for the mostly non-technical audience.

Tom is now aware that he is under even more time pressure as the Meredith avatar is still moving around the room. Realising his mistake, he uses the voice interface as a query language.

“Show me all communications with Malaysia.”
“Telephone or video?”
“Video.”

This brings up a more conventional looking GUI window because not everything in virtual reality needs to be three-dimensional. It’s always tempting for a 3D programmer to re-implement everything, but it’s also possible to embed 2D GUI applications into a virtual world.

Tom looks at a conventional 2D display of file icons inside VR. Disclosure (1994)

The window shows a thumbnail icon for each recorded video conference call. This isn’t very helpful, so Tom again decides that a voice query will be much faster than looking at each one in turn.

“Show me, uh, the last transmission involving Meredith.”

There’s a short 2D transition effect swapping the thumbnail icon display for the video call itself, which starts playing at just the right point for plot purposes.

Tom watches a previously recorded video call made by Meredith (right). Disclosure (1994)

While Tom is watching and listening, Meredith is still typing commands. The camera orbits around behind the video conference call window so we can see the Meredith avatar approach, which also shows us that this window is slightly three dimensional, the content floating a short distance in front of the frame. The film then cuts away briefly to show Meredith confirming her “kill all” command. The video conference recordings are deleted, including the one Tom is watching.

Tom is informed that Meredith (seen here in the background as a wireframe avatar) is deleting the video call. Disclosure (1994)

This is also the moment when the downstairs VIPs return to the hotel suite, so the scene ends with Tom managing to sneak out without being detected.

Virtual reality has saved the day for Tom. The documents and video conference calls have been deleted by Meredith, but he knows that they once existed and has a colleague retrieve the files he needs from the backup tapes. (Which is good writing: the majority of companies shown in film and TV never seem to have backups for files, no matter how vital.) Meredith doesn’t know that he knows, so he has the upper hand to expose her plot.

Analysis

How believable is the interface?

I won’t spend much time on the hardware, since our focus is on file browsing in three dimensions. From top to bottom, the virtual reality system starts as believable and becomes less so.

Hardware

The headset and glove look like real VR equipment, believable in 1994 and still so today. Having only one glove is unusual, and makes impossible some of the common gesture actions described in chapter 5 of Make It So, which require both hands.

The “laser scanners” that create the 3D geometry and texture maps for the 3D avatar and perform real time body tracking would more likely be cameras, but that would not sound as cool.

And lastly the walking platform apparently requires our user to stand on large marbles or ball bearings and stay balanced while wearing a headset. Uh…maybe…no. Apologetics fails me. To me it looks like it would be uncomfortable to walk on, almost like deterrent paving.

Software

The Corridor, unlike the 3D file browser used in Jurassic Park, is a special effect created for the film. It was a mostly-plausible, near future system in 1994, except for the photorealistic avatar. Usually this site doesn’t discuss historical context (the  “new criticism” stance), but I think in this case it helps to explain how this interface would have appeared to audiences almost two decades ago.

I’ll start with the 3D graphics of the virtual building. My initial impression was that The Corridor could have been created as an interactive program in 1994, but that was my memory compressing the decade. During the 1990s 3D computer graphics, both interactive and CGI, improved at a phenomenal rate. The virtual building would not have been interactive in 1994, was possible on the most powerful systems six years later in 2000, and looks rather old-fashioned compared to what the game consoles of the 21st C can achieve.

For the voice interface I made the opposite mistake. Voice interfaces on phones and home computing appliances have become common in the second decade of the 21st C, but in reality are much older. Apple Macintosh computers in 1994 had text-to-speech synthesis with natural sounding voices and limited vocabulary voice command recognition. (And without needing an Internet connection!) So the voice interface in the scene is believable.

The multi-user aspects of The Corridor were possible in 1994. The wireframe avatars for users not in virtual reality are unflattering or perhaps creepy, but not technically difficult. As a first iteration of a prototype system it’s a good attempt to span a range of hardware capabilities.

The virtual reality avatar, though, is not believable for the 1990s and would be difficult today. Photographs of the body, made during the startup scan, could be used as a texture map for the VR avatar. But live video of the face would be much more difficult, especially when the face is partly obscured by a headset.

How well does the interface inform the narrative of the story?

The virtual reality system in itself is useful to the overall narrative because it makes the Digicom company seem high tech. Even in 1994 CD-ROM drives weren’t very interesting.

The Corridor is essential to the tension of the scene where Tom uses it to find the files, because otherwise the scene would be much shorter and really boring. If we ignore the virtual reality these are the interface actions:

  • Tom reads an email.
  • Meredith deletes the folder containing those emails.
  • Tom finds a folder full of recorded video calls.
  • Tom watches one recorded video call.
  • Meredith deletes the folder containing the video calls.

Imagine how this would have looked if both were using a conventional 2D GUI, such as the Macintosh Finder or MS Windows Explorer. Double click, press and drag, double click…done.

The Corridor slows down Tom’s actions and makes them far more visible and understandable. Thanks to the virtual reality avatar we don’t have to watch an actor push a mouse around. We see him moving and swiping, be surprised and react; and the voice interface adds extra emotion and some useful exposition. It also helps with the plot, giving Tom awareness of what Meredith is doing without having to actively spy on her, or look at some kind of logs or recordings later on.

Meredith, though, can’t use the VR system because then she’d be aware of Tom as well. Using a conventional workstation visually distinguishes and separates Meredith from Tom in the scene.

So overall, though the “action” is pretty mundane, it’s crucial to the plot, and the VR interface helps make this interesting and more engaging.

How well does the interface equip the character to achieve their goals?

As described in the film itself, The Corridor is a prototype for demonstrating virtual reality. As a file browser it’s awful, but since Tom has lost all his normal privileges this is the only system available, and he does manage to eventually find the files he needs.

At the start of the scene, Tom spends quite some time wandering around a vast multi-storey building without a map, room numbers, or even coordinates overlaid on his virtual view. Which seems rather pointless because all the files are in one room anyway. As previously discussed for Johnny Mnemonic, walking or flying everywhere in your file system seems like a good idea at first, but often becomes tedious over time. Many actual and some fictional 3D worlds give users the ability to teleport directly to any desired location.

Then the file drawers in each cabinet have no labels either, so Tom has to look carefully at each one in turn. There is so much more the interface could be doing to help him with his task, and even help the users of the VR demo learn and explore its technology as well.

Contrast this with Meredith, who uses her command line interface and 2D GUI to go through files like a chainsaw.

Tom becomes much more efficient with the voice interface. Which is just as well, because if he hadn’t, Meredith would have deleted the video conference recordings while he was still staring at virtual filing cabinets. However neither the voice interface nor the corresponding file display need three dimensional graphics.

There is hope for version 2.0 of The Corridor, even restricting ourselves to 1994 capabilities. The first and most obvious is to copy 2D GUI file browsers, or the 3D file browser from Jurassic Park, and show the corresponding text name next to each graphical file or folder object. The voice interface is so good that it should be turned on by default without requiring the angel. And finally add some kind of map overlay with a you are here moving dot, like the maps that players in 3D games such as Doom could display with a keystroke.

Film making challenge: VR on screen

Virtual reality (or augmented reality systems such as Hololens) provide a better viewing experience for 3D graphics by creating the illusion of real three dimensional space rather than a 2D monitor. But it is always a first person view and unlike conventional 2D monitors nobody else can usually see what the VR user is seeing without a deliberate mirroring/debugging display. This is an important difference from other advanced or speculative technologies that film makers might choose to include. Showing a character wielding a laser pistol instead of a revolver or driving a hover car instead of a wheeled car hardly changes how to stage a scene, but VR does.

So, how can we show virtual reality in film?

There’s the first-person view corresponding to what the virtual reality user is seeing themselves. (Well, half of what they see since it’s not stereographic, but it’s cinema VR, so close enough.) This is like watching a screencast of someone else playing a first person computer game, the original active experience of the user becoming passive viewing by the audience. Most people can imagine themselves in the driving seat of a car and thus make sense of the turns and changes of speed in a first person car chase, but the film audience probably won’t be familiar with the VR system depicted and will therefore have trouble understanding what is happening. There’s also the problem that viewing someone else’s first-person view, shifting and changing in response to their movements rather than your own, can make people disoriented or nauseated.

A third-person view is better for showing the audience the character and the context in which they act. But not the diegetic real-world third-person view, which would be the character wearing a geeky headset and poking at invisible objects. As seen in Disclosure, the third person view should be within the virtual reality.

But in doing that, now there is a new problem: the avatar in virtual reality representing the real character. If the avatar is too simple the audience may not identify it with the real world character and it will be difficult to show body language and emotion. More realistic CGI avatars are increasingly expensive and risk falling into the Uncanny Valley. Since these films are science fiction rather than factual, the easy solution is to declare that virtual reality has achieved the goal of being entirely photorealistic and just film real actors and sets. Adding the occasional ripple or blur to the real world footage to remind the audience that it’s meant to be virtual reality, again as seen in Disclosure, is relatively cheap and quick.
So, solving all these problems results in the cinematic trope we can call Extradiegetic Avatars, which are third-person, highly-lifelike “renderings” of characters, with a telltale Hologram Projection Imperfection for audience readability, that may or may not be possible within the world of the film itself.

The Thanatorium: Usher Panel

The thanatorium is a speculative device for assisted suicide in Soylent Green. Suicide and death are not easy topics and I will do my best to address them seriously. Let me first take a moment to direct anyone who is considering or dealing with suicide to please stop reading this and talk to someone about it. I am unqualified to address—and this blog is not the place to work through—such issues.

There are four experiences to look at in the interface and service design of the Thanatorium: The patient, their beneficiaries, the usher to the beneficiaries, and the attendants to the patient. This post is about the interface for the usher. This Thanatorium personnel is there as a stage manager of sorts, both to help the patient and the beneficiaries go where they need to go, ensure the beneficiaries do not do what they must not, and run the tech aspects of the ceremony.

The usher, left, ushing.

Note that—as I backworlded in the last post—these notes presume that the reason the beneficiaries are separated from the patients are to prevent them from trying to stop the event, and to minimize distractions during the cinerama display for gross biochemical reasons. Also recall that we’re having to go with a best-guess as to what the usual experience is, since we only see Thorn’s tardy thuggery in the film.

The usher’s tasks

Based on what we see in the film, the usher has a lot to do for each event…

  • Receive the patient’s preferences (music category, color, whatever other questions intake asked before we join that scene) from the intake personnel 
  • Escort the patient to the “theater” and the beneficiaries to the observation room
  • Set the color of the light and the music to the patient’s preferences
  • Close the portal for the hemlock drinking
  • Open the portal for last farewells
  • Close the portal for the cinerama display
  • Start the cinerama display
  • Get help if the patient gets up or otherwise interrupts the ceremony
  • Wait for when the patient dies
  • Open the portal to view the body’s being shuttled away
  • Ensure the beneficiaries behave, answer any questions
  • Escort the beneficiaries back to the lobby
A screen shot from the movie showing the existing usher panel.

The interface barely touches on any of this

With all that in mind, we can see that this interface is woefully ill-equipped for any of his tasks. In the prior post I argue that the features for speaking to the patient—the speaker, the audio jack, and the SPEAKING PERMITTED indicator—should be separated from the usher’s stage manager functions. So we’re only going to pay attention in this post to the row of backlit rocker toggles labeled PORTAL, EFFECTS, CHAMBER 2, AUDIO, VISUAL, CHAMBER 1 and a little bit of the authorization key that looks like a square metal button in the screen cap above. And note I’m going to make suggestions that are appropriate to the early 1970s rather than use either modern real-world or speculative interface technologies.


First, that authorization key is pretty cool

The fact that it’s a featureless, long metal cuboid is so simple it feels sci-fi. Even the fact that its slot is unlabeled is good—it would help prevent a malicious or grief-panicked user from figuring out how to take control. You could even go one step further and have a hidden magnetic switch, so there’s not even a slot to clue in users. Production designer note, though, this means that the panel needs to be wood (or something non-magnetic) rather than a ferromagnetic metal. Aluminum, maybe, since it’s paramagnetic, but you also don’t want anything that can scratch or wear easily and give away the position of the secret spot.

A side view of a magnetic cabinet lock. When the magnet gets close to the right spot on the cabinet door, it pulls the latching mechanism open, allowing the door to be opened.
This is a cabinet lock, but the same principle would apply.

But, the buttons don’t match the scene

The PORTAL button never changes state, though we see the portal open and close in the scene. AUDIO is dim though we hear the audio. Maybe dim equals on? No, because VISUAL is lit. There’s some gymnastics we could do to apologize for this, but Imma give up and just say it’s just a moviemaking error.

And they are poorly clustered

Why is CHAMBER 2 before CHAMBER 1? Why are the three AV buttons split up by CHAMBER 2? A more reasonable chunking of these would be PORTAL on its own, CHAMBER 1 & CHAMBER 2 together, and the remaining A/V buttons together. These groups should be separated to make them easier to identify and help avoid accidental activation (though the stakes here are pretty low.)

One square by itself labeled PORTAL. Two squares side-by-side labeled CHAMBER 1 and CHAMBER 2. And three squares together labeled AUDIO, VISUAL, and EFFECTS.
If we were just dealing with these 6 buttons, this might be a reasonable clustering. But, read on…

The PORTAL button is the wrong type and orientation

Look close at the screen shot and you’ll see that each button consists of three parts. A white, back-lit square which bears the label, and two black pushbuttons that act like rocker switches. That is, press the upper one in, and the lower one pops out. Press that popped-out lower one in, and the upper one pops out again. When the lower button is pressed in, the button is “on,” which you can tell because those are the only ones with the upper button popped out and the back light illuminated.

Rocker switches are good for things with two mutually exclusive states, like ON and OFF. The PORTAL button is the only one for which this makes unambiguous sense, with its two states being OPEN and CLOSED. But, we have to note that it is poorly mapped. The button has a vertical orientation, but the portal closes from right to left. It means the usher has to memorize which toggle state is open and which one is closed. It would more usable to have an inferrable affordance. Cheapest would be to turn the button sideways so it maps more clearly, but an even tighter mapping would be a slider mounted sideways with OPEN and CLOSED labels. I don’t think the backlit status indicator is necessary here because there’s already a giant signal of the state of the portal, and that’s the adjacent portal.

An image of a slider switch.

What do EFFECTS and CHAMBER even do?

What does the EFFECTS button do? I mean, if AUDIO and VISUAL have their own controls, what’s left? Lasers? A smoke machine? Happiness pheromones? (I’m getting The Cabin in the Woods vibes here.) Whatever it is, if there are multiple, they should have individual controls, in case the patient wants one but not the other, or if there’s any variability that needs controlling.

Also what do CHAMBER 1 and CHAMBER 2 do? It’s very poor labeling. What chambers do they refer to? Maybe the observation room is chamber 1 and the theater is chamber 2? If so, different names could save the usher’s having to memorize them. Also, what do these switches control? Lights? Door locks? We would need to know to really make design recommendations for these.

The AV controls are incomplete

Which takes us to AUDIO, and VISUAL. Each of these is missing something.

Sure, they might need ON/OFF controls as we see here. But how about a volume control to accommodate the hard-of-hearing and the sound-sensitive? How about a brightness control for the video? These could have an OFF state and replace the toggle switches.

We know from the movie itself that the service has offered Sol his choice of music genre. Where is the genre selector? This is a non-trivial problem since the number of genres is on the order of 1000. They probably don’t offer all of them, but at intake they do ask Sol his preference as an open-ended question, so it implies a huge selection. Radio band selectors would have made sense to audiences in the 1970s, and signal a huge number of options, but risk being “out of tune” and imply that it’s broadcast. So either have a small number of options with a 15° rotary switch (and rewrite the intake scene so Sol selects from a menu) or three 10-digit rotary switches with a “commit” momentary button, and have a small reference booklet hanging there.

I also want to believe that the theme of the video can be selected. Sol has chosen “nature” but you could imagine patients requesting for their end-of-life ceremony something else like “family,” “celestial,” “food” (given the diegesis, this should be first) or even “religious” (with a different one for each of the world’s twelve major religions). So it would make sense to have a video theme selector as well, say, on the order of 20 options. That could be a 15° rotary switch. Labeling gets tough, but it could just be numbers with an index label to the side.

I’m going to presume that they never need scrubbing controls (REWIND or FAST FORWARD) for the AV. The cinerama plays through once and stops. Sudden rewinding or fast forwarding would be jarring for the patient and ruin the immersion. Have a play button that remains depressed while the cinerama is ongoing. But if the patient passes more quickly than expected, a RESET button would make sense. So would a clock or a countdown timer, since Sol had confirmed at intake that it would be at least 20 minutes, and to let the usher know how much time they have left to get those neurotransmitter numbers up up up.

Some controls are straight up missing

How does an usher set the lights according to the patient’s preferences? They ask at intake, and we see Sol’s face washed with a soothing amber color once the attendants leave, so there should be a color selector. Three RGB slide potentiometers would provide perfect control, but I doubt anyone would quibble that the green they’d asked for was #009440 and not #96b300, so you could go with a selector. The XKCD color survey results show that there are on the order of about 30 colors, so something similar to the video-theme selector above would work, with a brightness potentiometer to the side.

I will always be in awe of this undertaking and visualization, Randall Monroe.

These controls ought to be there

The patient experience is a bit of a show, so to signal its beginning and end, there should be lighting controls for the usher to dim and raise the lights, like in a theater. So let’s add those.

Also, the usher has a minor medical task to accomplish: Monitoring the health of the patient to know when they’ve passed. The three metrics for clinical death are a cessation of all three of…

  1. breath
  2. blood flow
  3. brain activity

…so there should be indicators for each of these. As discussed in the medical chapter of the book, this is ideally a display of values over time, but in the resource-poor and elecromechanical world of Soylent Green, it might have to be a collection of gauges, with an indicator bulb near the zero for when activity has stopped. A final, larger indicator bulb should light when all three gauges are still. To really underscore the morbidness of this interface, all those indicators should be green.

A comp showing the three clinical death gauges and incdicators, as described.

If you buy my backworlding, i.e. that part of the point of preventing interruptions is to maximize the dopamine and serotonin being released into the patient’s body, there should also be status indicators showing the level of these neurotransmitters in the patient’s bloodstream. They can be the same style of gauges, but I’d add a hand drawn arrow to some point along the chapter ring that reads “quota.” Those indicators should be larger than the clinical death indicators to match their importance to Soylent’s purposes.

Lastly, thinking of Thorn’s attack, the usher should have a panic button to summon help if the patient or the beneficiaries are getting violent (especially once they discover they’re locked in.) This should be hidden under the panel so it can be depressed secretly.

Where should this panel go?

As described in the beneficiaries post we’re going to leave the communication interface just below the portal, where they are now for those fleeting moments when they can wish the patient goodbye.

A screen shot of the movie showing Thorn at the portal addressing the usher, angrily, as usual.

And there’s no need to put the usher’s controls under the nose of the beneficiaries. (In fact with the medical monitoring it would be kind of cruel.) So let the usher have a lectern beside the door, in a dim pool of light, and mount the controls to the reading top. (Also give them a stool to rest on, have we learned nothing?) Turn the lectern such that the interface is not visible to beneficiaries in the room. This lets the usher remain respectfully out of the center of attention, but in a place where they can keep an eye on both the patient when the portal is open, and the beneficiaries throughout.

Looks cheap? Perfect.

In total, the lectern panel would look something like this…

The “READY” indicators are explained in the attendant’s post.

…and the scene could go something like this…

  • Interior. Thanatorium observation room.
  • The Usher escorts Thorn into the room. Thorn rushes to the portal. The usher steps behind a lectern near the door.
  • Usher
  • It’s truly a shame you missed the overture.
  • The Usher slides a switch on the lectern panel, and the portal closes.
  • Thorn
  • I want to see him.
  • Usher, looking down at his interface
  • That is prohibited during the ceremony.
  • Worm’s eye view. Thorn takes a few steps toward him and knocks the lectern to the ground. It falls with its interface in the foreground. In the background, we see Thorn slam the usher against the wall.
  • Thorn
  • Well I can assure you, open that damned thing right now, or I swear to God you’ll die before he does!
  • Usher
  • OK, OK!
  • The usher falls to his hands and knees and we see him slide the switch to open the portal. Thorn steps back to it, and the usher gets on his feet to right the lectern

The Thanatorium: A beneficiary’s experience

The thanatorium is a speculative service for assisted suicide in Soylent Green. Suicide and death are not easy topics and I will do my best to address them seriously. Let me first take a moment to direct anyone who is considering or dealing with suicide to please stop reading this and talk to someone about it. I am unqualified to address—and this blog is not the place to work through—such issues.

There are four experiences to look at in the interface and service design of the Thanatorium: The patient, their beneficiaries, the usher, and the attendants to the patient. This post is about the least complicated of the bunch, the beneficiaries.

Thorn’s experience

We have to do a little extrapolation here because the way we see it in the movie is not the way we imagine it would work normally. What we see is Thorn entering the building and telling staff there to take him to Sol. He is escorted to an observation room labeled “beneficiaries only” by an usher. (Details about the powerful worldbuilding present in this label can be found in the prior post.) Sol has already drunk the “hemlock” drink by the time Thorn enters this room, so Sol is already dying and the robed room attendants have already left.

Aaand I just noticed that the walls are the same color as the Soylent. Ewww.

This room has a window view of the “theater” proper, with an interface mounted just below the window. At the top of this interface is a mounted microphone. Directly below is an intercom speaker beside a large status alert labeled SPEAKING PERMITTED. When we first see the panel this indicator is off. At the bottom is a plug for headphones to the left, a slot for a square authorization key, and in the middle, a row of square, backlit toggle buttons labeled PORTAL, EFFECTS, CHAMBER 2, AUDIO, VISUAL, and CHAMBER 1. When the Sol is mid-show, EFFECTS and VISUAL are the only buttons that are lit.

When the usher closes the viewing window, explaining that it’s against policy for beneficiaries to view the ceremony, Thorn…uh…chokes him in order to persuade him to let him override the policy.

Persuasion.

“Persuaded,” the usher puts his authorization key back in the slot. The window opens again. Thorn observes the ceremony in awe, having never seen the beautiful Earth of Sol’s youth. He mutters “I didn’t know” and “How could I?” as he watches. Sol tries weakly to tell Thorn something, but the speaker starts glitching, with the SPEAKING PERMITTED INDICATOR flashing on and off. Thorn, helpfully, pounds his fist on the panel and demands that the usher do something to fix it. The user gives Thorn wired earbuds and Thorn continues his conversation. (Extradiegetically, is this so they didn’t have to bother with the usher’s overhearing the conversation? I don’t understand this beat.) The SPEAKING PERMITTED light glows a solid red and they finish their conversation.

Yes, that cable jumps back and forth like that in the movie during the glitch. It was a simpler time.

Sol dies, and the lights come up in the chamber. Two assistants come to push the gurney along a track through a hidden door. Some mechanism in the floor catches the gurney, and the cadaver is whisked away from Thorn’s sight.

Regular experience?

So that’s Thorns corrupt, thuggish cop experience of the thanatorium. Let’s now make some educated guesses about what this might imply for the regular, non-thug experience for beneficiaries.

  1. The patient and beneficiaries enter the building and greeted by staff.
  2. They wait in queue in the lobby for their turn.
  3. The patient is taken by attendants to the “theater” and the beneficiaries taken by the usher to the observation room.
  4. Beneficiaries witness the drinking of the hemlock.
  5. The patient has a moment to talk with the beneficiaries and say their final farewells.
  6. The viewing window is closed as the patient watches the “cinerama” display and dies. The beneficiaries wait quietly in the observation room with the usher.
  7. The viewing window is opened as they watch the attendants wheel the body into the portal.
  8. They return to the lobby to sign some documents for benefits and depart.

So, some UX questions/backworlding

We have to backworld some of the design rationales involved to ground critique and design improvements. After all, design is the optimization of a system for a set of effects, and we want to be certain about what effects we’re targeting. So…

Why would beneficiaries be separated from the patient?

I imagine that the patient might take comfort from holding the hands or being near their loved ones (even if that set didn’t perfectly overlap with their beneficiaries). So why is there a separate viewing room? There are a handful of reasons I can imagine, only one of which is really satisfying.

Maybe it’s to prevent the spread of disease? Certainly given our current multiple pandemics, we understand the need for physical separation in a medical setting. But the movie doesn’t make any fuss about disease being a problem (though with 132,000 people crammed into every square mile of the New York City metropolitan area you’d figure it would be), and in Sol’s case, there’s zero evidence in the film that he’s sick. Why does the usher resist the request from Thorn if this was the case? And why wouldn’t the attendants be in some sort of personal protective gear?

Maybe it’s to hide the ugly facts of dying? Real death is more disconcerting to see than most people are familiar with (take the death rattle as one example) and witnessing it might discourage other citizens from opting-in for the same themselves. But, we see that Sol just passes peacefully from the hemlock drink, so this isn’t really at play here.

Maybe it’s to keep the cinerama experience hidden? It’s showing pictures of an old, bountiful earth that—in the diegesis—no longer exists. Thorn says in the movie that he’s too young to know what “old earth” was like, so maybe this society wants to prevent false hope? Or maybe to prevent rioting, should the truth of How Far We’ve Fallen get out? Or maybe it’s considered a reward for patients opting-in to suicide, thereby creating a false scarcity to further incentivize people to opt-in themselves? None of this is super compelling, and we have to ask, why does the usher give in and open the viewport if any of this was the case?

That blue-green in the upper left of this still is the observation booth.

So, maybe it’s to prevent beneficiaries from trying to interfere with the suicide. This society would want impediments against last-minute shouts of, “Wait! Don’t do it!” There’s some slight evidence against this, as when Sol is drinking the Hemlock, the viewing port is wide open, so beneficiaries might have pounded on the window if this was standard operating procedure. But its being open might have been an artifact of Sol’s having walked in without any beneficiaries. Maybe the viewport is ordinarily closed until after the hemlock, opened for final farewells, closed for the cinerama, and opened again to watch as the body is sped away?

Ecstasy Meat

This rationale supports another, more horrible argument. What if the reason is that Soylent (the company) wants the patient to have an uninterrupted dopamine and seratonin hit at the point of dying, so those neurotransmitters are maximally available in the “meat” before processing? (Like how antibiotics get passed along to meat-eaters in industrialized food today.) It would explain why they ask Sol for his favorite color in the lobby. Yes it is for his pleasure, but not for humane reasons. It’s so he can be at his happiest at the point of death. Dopamine and seratonin would make the resulting product, Soylent green, more pleasurable and addictive to consumers. That gives an additional rationale as to why beneficiaries would be prevented from speaking—it would distract from patients’ intense, pleasurable experience of the cinerama.

A quickly-comped up speculative banner ad reading “You want to feel GOOD GOOD. Load up on Soylent Green today!”
Now, with more Clarendon.

For my money, the “ecstasy meat” rationale reinforces and makes worse the movie’s Dark Secret, so I’m going to go with that. Without this rationale, I’d say rewrite the scene so beneficiaries are in the room with the patient. But with this rationale, let’s keep the rooms separate.

Beneficiary interfaces

Which leads us to rethinking this interface.

Beneficiary interfaces

A first usability note is that the SPEAKING PERMITTED indicator is very confusing. The white text on a black background looks like speaking is, currently, permitted. But then the light behind it illuminates and I guess, then speaking is permitted? But wait, the light is red, so does that mean it’s not permitted, or is? And then adding to the confusion, it blinks. Is that the glitching, or some third state? Can we send this to its own interface thanatorium? So to make this indicator more usable, we could do a couple of things.

  • Put a ring of lights around the microphone and grill. When illuminated, speaking is permitted. This presumes that the audience can infer what these lights mean, and isn’t accessible to unsighted users, but I don’t think the audio glitch is a major plot point that needs that much reinforcing; see above. If the execs just have to have it crystal clear, then you could…
  • Have two indicators, one reading SPEAKING PERMITTED and another reading SILENCE PLEASE, with one or the other always lit. If you had to do it on the cheap, they don’t need to be backlit panels, but just two labeled indicator lamps would do.

And no effing blinking.

Thorn voice: NO EFFING BLINKING!

I think part of the affective purpose of the interface is to show how cold and mechanistic the thanatorium’s treatment of people are. To keep that, you could add another indicator light on the panel labeled somewhat cryptically, PATIENT. Have it illuminated until Sol passes, and then have a close up shot when it fades, indicating his death.

Ah, yes, good to have a reminder that’s why he’s a critic and not a working FUI designer.

A note on art direction. It would be in Soylent’s and our-real-world interest to make this interface feel as humane as possible. Maybe less steel and backlit toggles? Then again, this world is operating on fumes, so they would make do with what’s available. So this should also feel a little more strung together, maybe with some wires sticking out held together with electrical tape and tape holding the audio jack in place.

Last note on the accommodations. What are the beneficiaries supposed to do while the patient is watching the cinerama display? Stand there and look awkward? Let’s get some seats in here and pipe the patient’s selection of music in. That way they can listen and think of the patient in the next room.

If you really want it to feel extradiegetically heartless, put a clock on the wall by the viewing window that beneficiaries can check.


Once we simplify this panel and make the room make design sense, we have to figure out what to do with the usher’s interface elements that we’ve just removed, and that’s the next post.

Thanatorium: “Beneficiaries” only

In the subsequent post of the Soylent Green reviews, I’m going to talk about the design of the viewing room and the interface there. But first I need to talk about the design of something outside the viewing room. When Thorn enters the building and tells the staff there to take him to Sol, who is there to commit suicide, they pass a label on the wall reading “beneficiaries only.” This post is about the heavy worldbuilding provided by the choice of that one word, “beneficiaries.”

Here let me repeat my mantra that suicide is not an easy topic. Anyone who is considering or dealing with suicide to please stop reading this and talk to someone about it. I am unqualified to address—and this blog is not the place to work through—such issues.

It’s totally weird to call the people witnessing the suicide “beneficiaries,” right? Like their defining characteristic is that they get something out of the death? That’s crass. Shouldn’t they be called “loved ones” or something more sensitive?

To answer that question, we need to talk about Reverend Thomas Robert Malthus, seen here in a still from the movie.

Just to be clear, this is not an actual still. This is a Midjourney image.

In 1798, this clergyman anonymously published a book called An Essay on the Principle of Population, Chapter 11 of which describes what has come to be known as a Malthusian Crisis. This happens when a given population, which tends to grow exponentially, surpasses its ability to feed itself, which tends to grow linearly. The result is a period of strife, starvation, and warfare where the population numbers “correct themselves” back down to what can be sustained.

It would be irresponsible of me to invoke Malthus without pointing out that many people have taken this argument to dark and unethical conclusions—specifically almost always some sort of top-down population control with anti-poor, racist, or genocidal undertones. Sometimes overtones. Compare freely the English Poor Laws as they were curtailed by the Poor Law Amendment Act of 1834, the British government’s approach to famine in Ireland and India, social Darwinism, eugenics, the Holocaust, India’s forced sterilizations, China’s former one-child policy, and a lot of knee-jerk conservatism today. “iF We hElP ThE PoOr, It oNlY EnCoUrAgEs tHeM To hAvE MoRe cHiLdReN AnD ThErEbY ExAcErBaTe pOvErTy!” You may recognize echoes of this oversimplification from some recent indie sci-fi.

Though this gives me the opportunity to link to the Half-Earth Project. Hat tip mashable.

And I would be remiss if I didn’t make mention of the number of times Malthus has been been debunked. Scientific American did it. Forbes did it. These guys did it. Lots of people have done it. In short, we are not herds of helpless animals subject to brutal laws of nature. We think. We can invent industries and institutions and technologies that help us reduce waste, feed more, and more fairly distribute resources. We can raise people out of poverty with democracy, access to birth control, education, supply-chain citizenship, the empowerment of women, and even increasing vegetarian choices in diet. Had Malthus been able to predict Norman Borlaug and The Green Revolution, he would have quietly tossed his manuscript into the fire.

Anyway, the reason I bring all this up is because Soylent Green seems to be conceived as a Malthusian Crisis writ large. Given its timing I wouldn’t be surprised if writer Stanley R Greenberg had read himself some Paul Ehrlich, felt a panicked inspiration, and then grabbed his typewriter. The movie cites other factors, like climate change, that lead to its crisis; and illustrates contributing factors, like inequality, that exacerbate it. But with the titular green being food and the set decoration being mostly sweating extras lying about, the movie is a neon sign built to point at questions of feeding an overpopulated planet.

Which takes us back to that label outside the viewing room.


We’re all beneficiaries of that costume and set design. /s

One of the Malthusian levers to address the problem is systemically reducing the population. Speedy, public suicide services would be one of the tools by which a society could do that. And though this society does not go as far as Children of Men did (which placed ads for the suicide kits called Quietus throughout British cityscapes), characters in Soylent Green do speak about the “death benefit” several times in the movie. This points to survivors getting some payout when citizens suicide. Want to kill yourself? The government will pay your loved ones!

So though it might be seen as a poor, crass choice to refer to loved ones who are witnessing a suicide as “beneficiaries,” this framing within the diegesis helps encourage the act, by subtly implying though its choice of language that the loved ones are not there to witness an act of selfish escape as much as an act of kindness, both for their loved ones and the world.

Even the font of this wall sign—which looks like the least sci-fi typeface of all time: Clarendon—does not speak of sci-fi-ness, but of friendliness, early advertising, and 19th century broadsides. It nefariously adds a veneer of friendliness to what amounts to a murderous propaganda.

Naming is a narrative design choice, and the right name can do a lot of worldbuilding in a very small space, even if it’s misguided and driven by the popular panic of its times.

Report Card: Logan’s Run

LogansRun-Report-Card

For our purposes, Dome City is a service. Provided by the city’s ancestors to provide a “good life” for their cloned descendants in a sustainable way, i.e., a way that does not risk the problems of overpopulation. The “good life” in this case is a particular hedonistic vision full of fashion, time at the spa, and easy casual sex.

There’s an ethical, philosophical, and anthropological question on whether this is the “right” sort of life one would want to structure a service around. I suspect it’s a good conversation that will last at least a few beers. Fascinating as that question may be, looking into the interaction design requires us to accept those as a given and see how well the touchpoints help these personas address their goal in this framework.

Sci: F (0 of 4) How believable are the interfaces?

The Fade Out drug is the only, only interface that’s perfectly believable. And while I can make up some reasons the Clean Up Rig is cool, that’s clearly what I’m bringing to it, and the rest of the bunch, to an interface, has massive problems with fundamental believability and usability. Seriously, the movie is a study in bad design.

Fi: A (4 of 4)

How well do the interfaces inform the narrative of the story?

Here the interfaces are fine. The Lifeclock tells us of their forced life limit. The Circuit tells us of the easy sex. Fade Out tells of easy inebriation. New You of easy physical changes.

The interfaces help tell the story of this bizarre dystopia, help paint the “vast, silly spectacle” that Roger Ebert criticized when he write his original review in 1976.

Other interfaces help move the plot along in effective, if sometimes ham-handed ways, like the SandPhone and Aesculator Mark III. So even when they’re background tech, they help. Full marks.

Interfaces: D (1 of 4)
How well do the interfaces equip the characters to achieve their goals?

Sure, if you ignore all the usability problems and handwaving the movie does, the characters are getting what they want on a surface level. But ultimately, the service design of Dome City fails for every reason it could fail.

  • The system was poorly implemented.
  • Its touchpoints are unusable.
  • Its touchpoints don’t let its users achieve the system goals.

But the main reason it fails is that it fails to take into account some fundamental aspects of human nature, such as

  • Biophilia
  • The (entirely questionable) tendency towards punctuated serial monogamy in pair bonds
  • A desire for self-determination
  • Basic self-preservation.

If you don’t understand the goals of your users, you really have no hope of designing for them. And if you’re designing an entire, all-consuming world for those same users, misjudging the human universals puts your entire project—and their world—at risk.

Related lessons from the book

  • The Übercomputer’s all caps and fixed-width evoke “that look” of early computer interfaces (page 33), as does its OCR sans-serif typeface (page 37) and blue color (page 42).
  • The SandPhone would have been much more useful as Augmented Reality (chapter 8, page 157)
  • The Aesculaptor could use a complete revamp from the Medical Chapter (chapter 9, page 258), most notably using waveforms (page 263) and making it feel humane (page 281).
  • The Evidence Tray reminds us of multifactor authentication (page 118).
  • Of course The Circuit appears in the Sex chapter (chapter 13, page 293) and as my redesign showed, needed to modernize its matchmaking (page 295) use more subtle cues (page 301). Certainly Jessica-5 could have used a safeword (page 303).

New lessons

  • The Lifeclock reminds us to keep meaningful colors distinguishable.
  • The Circuit shows why a serial presentation democritizes options.
  • The Circuit also shows us that matchmaking must account for compatability, availability, and interest.
  • The Aesculaptor tells why a system should never fail into a worse state.
  • Carrousel implies that we don’t hide the worst of a system, but instead cover it in a dazzle pattern.
  • The improvements I suggested for the SandPhone imply that solving problems higher up the goal chain are much harder but more disruptive.
  • The Evidence Tray gives us the opposite of the “small interfaces” lesson (page 296), too large an interface can overpromise for small interactions.

I grew up in Texas, and had the chance to visit the Fort Worth Water Gardens and Market Center where some of the scenes were shot. So I have a weirdly personal connection to this movie. Despite that, on review, the interfaces just suck, bless their little interactive hearts. Use them as fodder for apologetics and perhaps as a cautionary tale, but little, little else.
