Klaatunian interior

DtESS-034

When the camera first follows Klaatu into the interior of his spaceship, we witness the first gestural interface seen in the survey. To turn on the lights, Klaatu places his hands in the air before a double column of small lights imbedded in the wall to the right of the door. He holds his hand up for a moment, and then smoothly brings it down before these lights. In response the lights on the wall extinguish and an overhead light illuminates. He repeats this gesture on a similar double column of lights to the left of the door.

The nice thing to note about this gesture is that it is simple and easy to execute. The mapping also has a nice physical referent: When the hand goes down like the sun, the lights dim. When the hand goes up like the sun, the lights illuminate.

He then approaches an instrument panel with an array of translucent controls; like a small keyboard with extended, plastic keys. As before, he holds his hand a moment at the top of the controls before swiping his hand in the air toward the bottom of the controls. In response, the panels illuminate. He repeats this on a similar panel nearby.

Having activated all of these elements, he begins to speak in his alien tongue to a circular, strangely lit panel on the wall. (The film gives no indication as to the purpose of his speech, so no conclusions about its interface can be drawn.)

Gort also operates the translucent panels with a wave of his hand. To her credit, perhaps, Helen does not try to control the panels, but we can presume that, like the spaceship, some security mechanism prevents unauthorized control.

Missing affordances

Who knows how Klaatu perceives this panel. He’s an alien, after all. But for us mere humans, the interface is confounding. There are no labels to help us understand what controls what. The physical affordances of different parts of the panels imply sliding along the surface, touch, or turning, not gesture. Gestural affordances are tricky at best, but these translucent shapes actually signal something different altogether.

Overcomplicated workflow

And you have to wonder why he has to go through this rigmarole at all. Why must he turn on each section of the interface, one by one? Can’t they make just one “on” button? And isn’t he just doing one thing: Transmitting? He doesn’t even seem to select a recipient, so it’s tied to HQ. Seriously, can’t he just turn it on?

Why is this UI even here?

Or better yet, can’t the microphone just detect when he’s nearby, illuminate to let him know it’s ready, and subtly confirm when it’s “hearing” him? That would be the agentive solution.

Maybe it needs some lockdown: Power

OK. Fine. If this transmission consumes a significant amount of power, then an even more deliberate activation is warranted, perhaps the turning of a key. And once on, you would expect to see some indication of the rate of power depletion and remaining power reserves, which we don’t see, so this is pretty doubtful.

Maybe it needs some lockdown: Security

This is the one concern that might warrant all the craziness. That the interface has no affordance means that Joe Human Schmo can’t just walk in and turn it on. (In fact the misleading bits help with a plausible diversion.) The “workflow” then is actually a gestural combination that unlocks the interface and starts it recording. Even if Helen accidentally discovered the gestural aspect, there’s little to no way she could figure out those particular gestures and start intergalactic calls for help. And remembering that Klaatu is, essentially, a space ethics reconn cop, this level of security might make sense.

Good morning, Korben

5E-alarm_notext

Korben’s alarm clock is a transparent liquid-crystal display that juts out from a panel at the foot of his bed. When it goes off, it emits a high-pitched repetitive whine. To silence it, Korben must sit up and pinch it between his fingers.

There’’s some subtle, wicked effeciveness to that deactivation. Like a regular alarm clock, the tactic is to emit some annoying sound that persists until the sleeper can rouse themselves enough to turn off the alarm. The usual problem with this tactic is that the sleeper is stupefied in his half-awakeness. If he can sleepily stop the alarm and just go back to sleep, he’ll do it. This clock dissuades sleepy flailing with its sharp-ish corners. After just a few times trying to do that and failing, the scratches on his hand will teach him. Even if the motion is memorized, the sleeper has to wake enough to target it properly and execute the simple but precise input.

The display itself shows the time in astronomical format, i.e. “02:00″, the date (Director Luc Besson‘s birthday), “18 MAR 2263″, and a temperature, 27.5° C.” Since this is quite warm, I presume this is the temperature outside.

Once Korben cancels the alarm, his apartment comes to life. Heavy-beat music begins to play and lights automatically illuminate near the fake-fish tank above the stove and in his cigarette dispenser.

All these signals combine to make it difficult for sleepy Korben to stay in bed past when awake Korben knows he should be up and moving.

Course-correction

The stage managers’ main raison d’être is to course-correct if and when victims begin to deviate from the path required of the ritual.

This begins with the Prep team, long before the victims enter the stage. For example, Jules’ hair dye and Marty’s laced pot. These corrections become more necessary and intense once the victims go on stage.

Making sure there are sexy times

The ritual requires that a sexy young couple have sexy times on stage before they suffer and die. “The mood” can be ruined by many things, but control has mechanisms to cope with most of them. We see three in the movie.

Temperature

The temperature can’t be too hot or too cold, but this isn’t something that can be set and forgot. What counts as the right temperature is a subjective call for the people involved and their circumstances, such as being drunk, or amount and type of clothes worn. Fortunately, the video-audio panopticon lets the stage managers know when a victim speaks about this directly, and do something about it. The moment Jules complains, for instance, Sitterson is able to reach over to a touch-screen display and tap the temperature a few degrees warmer.

Sitterson heats things up.

The gauge is an interesting study. It implies a range possible between 48 and 92 degrees Fahrenheit, each of which is uncomfortable enough to encourage different behaviors in the victims, without the temperature itself being life-threatening.

Moreover, we see that it’s a “blind” control. Before Sitterson taps it, he is only shown the current temperature as a blue rectangle that fills up four bars and that it is exactly 64 degrees. But if he knew he wanted it to be 76 degrees, what, other than experience or training, tells him where he should touch to get to that desired new temperature? Though the gauge provides immediate feedback, it still places a burden on his long-term memory. And for novice users, such unlabeled controls require a trial-and-error method that isn’t ideal. Even the slim area of white coloring at the top, which helpfully indicates temperatures warmer than cooler, appears too late to be useful.

Better would be to have the color alongside or under the gauge with smaller numbers indicated along its length such that Sitterson could identify and target the right temperature on the first try.

Libido

The next thing that can risk the mood is a lack of a victim’s amorous feelings. Should someone not be “feeling it,” Control can pipe sex pheromones to areas on stage. We see Hadley doing this by operating a throttle lever on the electronic-era control panel. After Hadley raises this lever, we see small plumes of mist erupt from the mossy forest floor that Jules and Curt are walking across.

Hadley introduces pheromones to the forest air.

This control, too, is questionable. Let’s first presume it’s not a direct control, like a light switch, but more of a set-point control, like a thermostat. Similar to the temperature gauge above, this control misses some vital information for Hadley to know where to set the lever to have the desired amount of pheromone in the air, like a parts-per-million labeling along the side. Perhaps this readout occurs on a 7-segment readout nearby or a digital reading on some other screen, but we don’t see it.

There is also no indication about how Hadley has specified the location for the pheromone release. It’s unlikely that he’s releasing this everywhere on stage, lest this become a different sort of ritual altogether. There must be some way for him to indicate where, but we don’t see it in use. Perhaps it is one of the lit square buttons to his right.

An interesting question is why the temperature gauge and pheromone controls, which are similar set-point systems, use not just different mechanisms, but mechanisms from different eras. Certainly such differentiation would help the stage managers’ avoid mistaking one for the other, and inadvertently turn a cold room into an orgy, so perhaps it is a deliberate attempt to avoid this kind of mistake.

Lights

The final variable that stands in the way of Jules’ receptiveness (the authors here must acknowledge their own discomfort in having to write about this mechanistic rape in our standard detached and observational tone) is the level of light. After she complains that it is too dark, Hadley turns a simple potentiometer and the “moonlight” on a soft bed of moss behind them grows brighter.

Control responds to Jules’ objection to the darkness.

This, too, is a different control than the others; though it controls what is essentially a floating-point variable. But since it is more of a direct control than the other two, its design as a hard-stop dial makes sense, and keeps it nicely differentiated from the others.

Marty’s Subliminal Messages

Over the course of the movie, several times we hear subliminal messages spoken to directly control Marty. We never see the inputs used by Control, but they do, at least on one occasion, actually influence him, and is one of the ways the victims are nudged into place.

Marty breaks the fourth wall

In addition to Dana & Curt’s almost not getting it on, another control-room panic moment comes when Marty accidentally breaks a lamp and finds one of the tiny spy cameras embedded throughout the cabin. Knowing that this level of awareness or suspicion could seriously jeopardize the scenario, Hadley bolts to a microphone where he says, “Chem department, I need 500 ccs of Thorazine pumped into room 3!”

Marty finds a spy camera

Hadley speaks a command to the Chem department

Careful observers will note while watching the scene that a menu appears on a screen behind him as he’s stating this. The menu lists the following four drugs.

  • Cortisol (a stress hormone)
  • Pheromones (a category of hormonal social signals, most likely sex pheromones)
  • Thorazine (interestingly, an antipsychotic known to cause drowsiness and agitation)
  • Rhohyptase (aka Rhohypnol, the date rape drug)

Given that content, the timing of the menu is curious. It appears, overlaid on the victim monitoring screen, the moment that Hadley says “500.” (Before he can even specify “Thorazine.”) How does it appear so quickly? Either there’s a team in the Chem department also monitoring the scene, and who had already been building a best-guess menu for what Hadley might want in the situation and they just happened to push it to Hadley’s screen at that moment; Or there’s an algorithmic voice- and goal-awareness system that can respond quickly to the phrase “500 ccs” and provide the top four most likely options. That last one is unlikely, since…

  • We don’t see evidence of it anywhere else in the movie
  • Hadley addresses the Chem department explicitly
  • We’d expect him to have his eyes on the display, ready to make a selection on its touch surface, if this was something that happened routinely

But, if we were designing the system today with integrated voice recognition capabilities, it’s what we’d do.

Curt suggests they stick together

After the attack begins on the cabin itself, Curt wisely tells the others, “Look, we’ve got to lock this place down…We’ll go room by room, barricade every window and every door. We’ve got to play it safe. No matter what happens, we have to stay together.” Turns out this is a little too wise for Hadley’s tastes. Sitterson presses two yellow, back-lit buttons on his control panel to open vents in the hallway, that emit a mist. As Curt passes by the vents and inhales, he pauses, turns to the others and says, “This isn’t right…This isn’t right, we should split up. We can cover more ground that way.”

Sitterson knocks some sense out of Curt.

This two-button control seems to indicate drug (single dose) and location, which is sensible. But if you are asking users to select from different variables, it’s a better idea to differentiate them by clustering and color, to avoid mistakes and enable faster targeting.

Locking the doors

Once the victims are in their rooms, Hadley acknowledges it’s time to, “Lock ‘em in.” Sitterson flips a safety cover and presses a back-lit rocker switch, which emits a short beep and bolts the doors to all the victims’ rooms at the same time.

Sitterson bolts the victims’ doors.

Marty in particular notices the loud “clunk” as the bolts slide into place. He tests the door and is confounded when he finds it is, in fact, locked tight. Control’s earlier concern about tipping their hand seems to matter less and less, since this is a pretty obvious manipulation.

The edge of the world

Bolted doors pale in comparison to the moment when Curt, Dana, and Holden violently encounter the limits of the stage. After the demolition team seals the tunnel to prevent escape that way, Curt tries to jump the ravine to the other side so he can fetch help. Unfortunately for him, the ravine is actually an electrified display screen, showing a trompe-l’œil illusion of the far side. By trying to jump the ravine, Curt unwittingly commits suicide by slamming into it.

Curt slams into the edges of the “world” of the cabin.

The effect of the screen is spectacular, full of arcs zipping along hexagonal lines and sparks flying everywhere. Dana and Holden rush to the edge of the cliff to watch him tumble down its vast, concave surface. It seems that if you’ve come this far, Control isn’t as concerned about tipping its hand as it is finishing the job.
