Rocky Horror Vivification Interfaces

As we continue to look at the interfaces in The Rocky Horror Picture Show, this post will focus on the interfaces used to bring Rocky to life. The fancy Latinate word for this is vivification.

Come up to the lab

The interfaces in the lab where the procedure happens are mounted on an illuminated glass-brick wall. They are heavy and industrial-looking, cased in powder coat red and bolted together. They connect by pipe conduits. It very much reminds me of the ghost containment panel in Ghostbusters, which world be released nine years later.

They include…

We’ll talk about the whole set in a later post, but for now let’s focus on the ones involved in the vivification scene—when Frank-N-Furter brings Rocky to life before the Transylvanian conventioneers. These devices are the Sonic Oscillator, the Reactor Power Input, and the Handwheel.

Screenshot from the movie showing a distance shot of the laboratory interfaces on the wall. Labels in dripping blood type read “Sonic Oscillator”, “Reactor Power Input”, and “Handwheel”. Arrows point from the label to the interface.

Throughout the scene, Frank-N-Furter acts as a dramatic ringleader, telling his helpers what to do next. He begins by calling to Riff Raff, who stands at the instrument panel. Frank shouts, “Throw open the switches on the Sonic Oscillator!” Which brings us to…

The Sonic Oscillator

Screenshot from the movie showing Frank at the vat pointing with an intense expression toward Riff Raff. At his side are Columbia and Magneta. Dripping blood typography reads “THROW OPEN THE SWITCHES ON THE SONIC OSCILLATOR”.

This box has two large, vertical lever switches on the left. To the right of the switches is a column with small, dim, cowled displays. (That right half is the Reactor Power Input, to be discussed below.) Riff Raff pulls each of the the levers down, and as he does so, one of the cowled screens illuminate with faint green oscilloscope waves. It has no other discernible effect.

Several critiques about this interface.

  • Up maps more intuitively to on, open, and more. The levers should be pushed up to turn the oscillators on.
  • If they’re critical they remain in an up position for a duration or to prevent accidental activation, it should either latch or the friction joint holding it in place should be very strong.
  • The prop makers were probably constrained to the size of available oscilloscopes, but the screens are quite small compared to their housing. If they are meant to be read at any distance, those screens should be larger, and the displays be reworked to be more legible.
  • These controls are poorly mapped to their actuators. Imagine the improvement: Levers half this height could be stacked on top of the other, and be much more clearly associated with their screens by dint of being adjacent to them and only to them. As it is, when off, the rightmost lever is closest to the screen it does not control.
  • The two levers are quite close to each other. If they are meant to be operated simultaneously, that’s fine, but in the scene Riff Raff operates them separately, so it’s not their only use. If they weren’t stacked to improve their mappings like I suggested above, they should at least be moved apart to decrease the risk of accidental activation.

Three More Triangles!

Next Frank shouts, “And step up the reactor power input three…more…points!

Screenshot from the movie showing Frank pointing dramatically to Riff Raff. Dripping blood typography reads “STEP UP THE REACTOR POWER INPUT THREE… MORE… POINTS!”

The right half of the box has an unlabeled, diamond-shaped dial on top, and, below, a set of eight red triangles arranged in a circle looking a bit like the Umbrella Corporation logo.

(Sorry about the darkness of these images. Keeping the illumination of the buttons visible means I can’t raise the midtone levels, like I could for the prior images.)

At Frank’s command, Riff Raff presses three alternating triangles in the umbrella control. (If numbering like a clock that goes to 8, he presses 5, then 7, then 1.) They illuminate as he presses them. With each button, the needle in the dial steps to the next graduation. Steam begins to escape from the nearby pipes (a side effect, one presumes). Neither the steam nor the reactor power input has any other discernible effect.

Several critiques about this interface.

  • The face should illuminate when the input is above zero for better readability, glanceability, and association with the illuminated buttons.
  • The needle is barely visible, especially from a distance. The needle should be as visible as the glowing buttons.
  • The umbrella-top arrangement of the buttons is poorly mapped. Up maps to more. Right also maps to more in left-to-right reading cultures. This clock wheel arrangement implies circularity, which makes no sense to modify a variable between 0 and 7.
  • Skipping places makes no sense. (The every-other button thing.) Had Frank asked to step it up five or more points, the interaction and display would have been awkward and error prone to both execute and read.
  • Presuming buttons show target value and the dial shows actual value, then they should be tightly mapped. Think of a thermostat where the target temperature is displayed adjacent to the actual temperature. See the comp below for a better suggestion of mapping.
  • If [measurement does not equal target] is an issue, then we need an alert. If the reading exceeds the setting, the setting button should blink; if it falls short, all buttons between the reading and the setting should blink to signal that it the value is not where it should be. Though, I have to note that if that kind of precision is called for, then it shouldn’t be buttons at all, but be a control that offers more precision, like a dial.
  • Riff Raff should just be able to press any button and have it and all the lower value buttons illuminate automatically. Press three, and one and two should illuminate without his having to press them. He shouldn’t have to press all three in sequence. It should also not prevent him from doing so, if he (or Frank) want to be dramatic.
  • Generally speaking, graduations should be labeled. This particular interface has few enough elements that I might give it a pass, since I suspect it can be easily subitized, positively (how many are lit) or negatively (how many are dim).
A comp showing a fan-shaped dial. The glowing fan is divided for 7 graduations. A needle points around 2.8. Above each graduation is a button. The first three are illuminated and glowing. The last four are not. The graphic has the “dripping blood” treatment seen throughout the graphics.

Much better. The comp raises the additional question of how it is turned off. I presume in the original they were toggle buttons that you would press again to turn off, so that could work here. So—press any but the current setting, and it changes. Press the current illuminated setting and the whole thing turns off. If the stakes are high enough, though, Riff might need a separate control or a safeguarded control. We can’t say because we don’t know what this actually does.

Put your hump into it, Riff!

After stepping up the reactor power three… more… points, Riff Raff kneels down to a handwheel, which he cranks clockwise to lower a ceiling-mounted apparatus from high in a cupola to just above the vat.

Screenshot from the movie: Riff Raff turning the handwheel while smiling creepily and looking toward the vat.

This is mechanical, which puts constraints on usability changes. Certainly that grip could be made wider and the axis could be raised to some more ergonomic position. (Or, given what we see on screen, it could be steam-powered and activated by a valve.) But note that, as it is, narratively, this does some things.

  1. It adds to the weight of the scene via the effort heuristic.
  2. It signals that Riff Raff is a servant, having to do difficult manual labor in a humbling position amid steam; which increases the surprise of his later mutiny. (And presages the awesome steam conversation scene in Alien four years later.)

The rainbow soup

The apparatus Riff lowers houses seven colored cylinders of matching-colored, viscous fluid. When they come within reach, Frank-N-Furter turns valves at the bottom of each one to allow the fluids to pour into the vat, turning its contents into a layered, upside-down rainbow.

Manual valves are a fine interface, since it appears precision is not required. This step is more improvisational art than science, it seems.

Aside: Watching this scene carefully I notice that even though the colored fluids are in an inexplicable order in the interface: yellow blue red purple orange blue green (no, I have no idea why there are two blues, maybe one was supposed to be indigo?), Curry takes pains to open them in rainbow order: red orange yellow green blue blue purple. Note this was *not* a reference to the rainbow flag, which goes in the opposite display order and which Gilbert Baker wouldn’t invent until three years after this film was released. It was Curry (or someone on set) paying attention to real-world light spectra.

Anyway, after enough of the fluid has been dropped to create a layered rainbow effect in the vat, Frank-N-Furter frantically closes the valves. (If you’re wondering, editing makes it difficult to tell in what order he closes the valves, but it seems random.) After a beat, Riff Raff cranks the handwheel counterclockwise to lift Rocky—who is gripping the ceiling-mounted apparatus—out of the vat. The rest of the procedure is analog and does not involve technological interfaces, but does involve a musical number in which Rocky is unwrapped like a reverse mummy, while singing.

Screenshot from the movie showing Frank on Riff Raff’s shoulders, gaping in awe at his creation Rocky, as Rocky is being unwrapped and exposing his physique. Dripping blood typography reads “SHA LA LA LA THAT AIN’T NO CRIME”.

That’s it. That’s how Rocky is brought to life. And, now I am happy to declare…

This is the best series of interfaces in the movie

Not for its usability. It’s fairly wretched for that (see lengthy notes above). But…

Diegetically, the unusability is a feature. First, by contributing to the perception to the conventioneers that big, dramatic science is happening before their eyes. It’s impressive theatrics. I think it could go even farther in seeming usable while still maintaining inscrutable complexity, but this does the trick for Transylvanians. Second, it builds on guild mentality. That is, the inscrutability helps deter others from thinking they could easily do it themselves. It’s a kind of job security through obscurity.

Extradiegetically, because the film is partly meant to mock B-movie sci-fi, the fact that they are…

  • poorly designed
  • pseudoscientific at best,
  • cinegenic, and
  • histrionic;

…they are perfect.

No notes.

I mean, 1800-ish words of notes.

But you know, “no notes.”

As if all this drama wasn’t enough. In the next post it’s going to get turned up to 11. Triple Contact Electro Magnet

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.

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.

An image showing the components of such a video selector, including the label.

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.

XKCD color graph showing the outlines with crowdsourced regions and labels. But please check out the full post as linked in the image caption. It’s so much more awesome than just this.
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.

An image of a lectern
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 Monster from the Id

The plastic educator has a side effect that serves as the mystery at the dark heart of the film. Use of the device gives rise to ““monsters from the id,”” which manifest while the user is asleep and attack the sleeper’’s enemies. Our first clue to the origins of the monster appear when Morbius explains the Krell gauges.

The encyclopedia registers a negligible amount of power.

“Gauges line the curving walls of the lab in stacks of two,” Morbius explains, ““Their calibrations appear to indicate that they are set in decimal series, each division recording exactly ten times as many amperes as the one preceding it. Ten times ten, times ten, times ten, times ten, times ten, on and on and on, row after row, gauge after gauge.””

He turns on the encyclopedia and a small bit of light appears on the first gauge. He turns on the plastic educator and the gauge shows a little more.

Asleep, Morbius’’ id manifests as a horrible monster.

This explanation helps to set up the awesome power of Morbius’’ monster when we see Morbius sleeping in the lab, and sixteen of the gauges are lit up. (It’s 10^16 times more powerful than an encyclopedia.) We know the (then) unbelievable technologies showed the barest sliver of a reading, and here they are blasting power to…somewhere.

After waking, both Morbius’’ monster and the power gauges fade.

The connection is severed as Morbius awakens, and within seconds the monster fades and the gauges behind him dim one by one.

Adams wrestles Morbius into the seat of the educator.

This dramatic link is underscored when the monster has come into the underground city to destroy Morbius, Adams, and Alta. As Adams wrestles Morbius down, we hear the angry pounding of the monster against the vault like doors, and see the gauges glowing and fluctuating wildly in the background.
