Eye of Agamotto (1 of 5)

This is one of those sci-fi interactions that seems simple when you view it, but then on analysis it turns out to be anything but. So set aside some time, this analysis will be one of the longer ones even broken into four parts.

The Eye of Agamotto is a medallion that (spoiler) contains the emerald Time Infinity Stone, held on by a braided leather strap. It is made of brass, about a hand’s breadth across, in the shape of a stylized eye that is covered by the same mystical sigils seen on the rose window of the New York Sanctum, and the portal door from Kamar-Taj to the same.

World builders may rightly ask why this universe-altering artifact bears a sigil belonging to just one of the Sanctums.

We see the Eye used in three different places in the film, and in each place it works a little differently.

  • The Tibet Mode
  • The Hong Kong Modes
  • The Dark Dimension Mode

Motion Detector

Johnny, with newly upgraded memory, goes straight to the hotel room where he meets the client’s scientists. Before the data upload, he quickly installs a motion detector on the hotel suite door. This is a black box that he carries clipped to his belt. He uses his thumb to activate it as he takes hold and two glowing red status lights appear.

Once placed on the door, there is just one glowing light. We don’t see exactly how Johnny controls the device, but for something this simple just one touch button would be sufficient.

jm-5-motion-detector-b-adjusted

A little later, after the brain upload (discussed in the next post), the motion detector goes off when four heavily armed Yakuza arrive outside the door. The single light starts blinking, and there’s a high pitched beep similar to a smoke alarm, but quieter. Continue reading

Itchy’s SFW Masturbation Chair

With the salacious introduction, “Itchy, I know what you’d like,” Saun Dann reveals himself as a peddler of not just booby trapped curling irons, but also softcore erotica! The Life Day gift he gives to the old Wookie is a sexy music video for his immersive media chair.

SWHS-Chair-03

The chair sits in the family living room, and has a sort of helmet fixed in place such that Itchy can sit down and rest his head within it. On the outside of the helmet are lights that continuously blink out of sync with each other and seem unrelated to the actual function of the chair. Maybe a fairy-lights power indicator?

Time circuits (which interface the Flux Capacitor)

BttF_137Time traveling in the DeLorean is accomplished in three steps. In the first, he traveler turns on the “time circuits” using a rocking switch in the central console. Its use is detailed in the original Back to the Future, as below.

In the second, the traveler sets the target month, day, year, hour, and minute using a telephone keypad mounted vertically on the dashboard to the left, and pressing a button below stoplight-colored LEDs on the left, and then with an extra white status indicator below that before some kind of commit button at the bottom.

In the third, you get the DeLorean up to 88 miles per hour and flood the flux capacitor with 1.21 gigawatts of power.

Seems simple.

It’s not… Continue reading

The bug VP

StarshipT_030

In biology class, the (unnamed) professor points her walking stick (she’s blind) at a volumetric projector. The tip flashes for a second, and a volumetric display comes to life. It illustrates for the class what one of the bugs looks like. The projection device is a cylinder with a large lens atop a rolling base. A large black plug connects it to the wall.

The display of the arachnid appears floating in midair, a highly saturated screen-green wireframe that spins. It has very slight projection rays at the cylinder and a "waver" of a scan line that slowly rises up the display. When it initially illuminates, the channels are offset and only unify after a second.

STARSHIP_TROOPERS_vdisplay

StarshipT_029

The top and bottom of the projection are ringed with tick lines, and several tick lines runs vertically along the height of the bug for scale. A large, lavender label at the bottom identifies this as an ARACHNID WARRIOR CLASS. There is another lavendar key too small for us to read.The arachnid in the display is still, though the display slowly rotates around its y-axis clockwise from above. The instructor uses this as a backdrop for discussing arachnid evolution and "virtues."

After the display continues for 14 seconds, it shuts down automatically.

STARSHIP_TROOPERS_vdisplay2

Interaction

It’s nice that it can be activated with her walking stick, an item we can presume isn’t common, since she’s the only apparently blind character in the movie. It’s essentially gestural, though what a blind user needs with a flash for feedback is questionable. Maybe that signal is somehow for the students? What happens for sighted teachers? Do they need a walking stick? Or would a hand do? What’s the point of the flash then?

That it ends automatically seems pointlessly limited. Why wouldn’t it continue to spin until it’s dismissed? Maybe the way she activated it indicated it should only play for a short while, but it didn’t seem like that precise a gesture.

Of course it’s only one example of interaction, but there are so many other questions to answer. Are there different models that can be displayed? How would she select a different one? How would she zoom in and out? Can it display aimations? How would she control playback? There are quite a lot of unaddressed details for an imaginative designer to ponder.

Display

The display itself is more questionable.

Scale is tough to tell on it. How big is that thing? Students would have seen video of it for years, so maybe it’s not such an issue. But a human for scale in the display would have been more immediately recognizable. Or better yet, no scale: Show the thing at 1:1 in the space so its scale is immediately apparent to all the students. And more appropriately, terrifying.

And why the green wireframe? The bugs don’t look like that. If it was showing some important detail, like carapice density, maybe, but this looks pretty even. How about some realistic color instead? Do they think it would scare kids? (More than the “gee-whiz!” girl already is?)

And lastly there’s the title. Yes, having it rotate accomodates viewers in 360 degrees, but it only reads right for half the time. Copy it, flip it 180º on the y-axis, and stack it, and you’ve got the most important textual information readable at most any time from the display.

Better of course is more personal interaction, individual displays or augmented reality where a student can turn it to examine the arachnid themselves, control the zoom, or follow up on more information. (Wnat to know more?) But the school budget in the world of Starship Troopers was undoubtedly stripped to increase military budget (what a crappy world that would be amirite?), and this single mass display might be more cost effective.

The Dropship

WallEDropShip-08

The Axiom Return Vehicle’s (ARV’s) first job is to drop off Eve and activate her for her mission on Earth. The ARV acts as the transport from the Axiom, landing on the surface of Earth to drop off Eve pods, then returning after an allotted time to retrieve the pods and return them to the Axiom.

The ARV drops Eve at the landing site by Wall-E’s home, then pushes a series of buttons on her front chest. The buttons light up as they’re pushed, showing up blue just after the arm clicks them. At the end of the button sequence, Eve wakes up and immediately begins scanning the ground directly in front of her. She then continues scanning the environment, leaving the ARV to drop off more Eve Pods elsewhere.

If It Ain’t Broke…

There’s an oddity in ARV’s use of such a crude input device to activate Eve. On first appearance, it seems like it’s a system that is able to provide a backup interface for a human user, allowing Eve to be activated by a person on the ground in the event of an AI failure, or a human-led research mission. But this seems awkward in use because Eve’s front contains no indication of what the buttons each do, or what sequence is required.

A human user of the system would be required to memorize the proper sequence as a physical set of relationships. Without more visual cues, it would be incredibly easy for the person in that situation to push the wrong button to start with, then continue pushing wrong buttons without realizing it (unless they remembered what sound the first button was supposed to make, but then they have one /more/ piece of information to memorize. It just spirals out of control from there).

What was originally for people is now best used by robots.

WallEDropShip-03

So if it’s not for humans, what’s going on? Looking at it, the minimal interface has strong hints of originally being designed for legacy support: large physical buttons, coded interface, and tilted upward for a person standing above it. BNL shows a strong desire to design out people, but leave interactions (see The Gatekeeper). This style of button interface looks like a legacy control kept by BNL because by the time people weren’t needed in the system anymore, the automated technology had already been adapted for the same situation.

Large hints to this come from the labels. Each label is an abstract symbol, with the keys grouped into two major areas (the radial selector on the top, and the line of large squares on the bottom). For highly trained technicians meant to interact only rarely with an Eve pod, these cryptic labels would either be memorized or referenced in a maintenance manual. For BNL, the problem would only appear after both the technicians and the manual are gone.

It’s an interface that sticks around because it’s more expensive to completely redo a piece of technology than simply iterate it.

Despite the information hurdles, the physical parts of this interface look usable. By angling the panel they make it easier to see the keypad from a standing position, and the keys are large enough to easily press without accidentally landing on the wrong one. The feedback is also excellent, with a physical depression, a tactile click, and a backlight that trails slightly to show the last key hit for confirmation.

If I were redesigning this I would bring in the ability for a basic- or intermediate-skill technician to use this keypad quickly. An immediate win would be labeling the keys on the panel with their functions, or at least their position in the correct activation sequence. Small hints would make a big difference for a technician’s memory.

WallEDropShip-04

To improve it even more, I would bring in the holographic technology BNL has shown elsewhere. With an overlay hologram, the pod itself could display real-time assistance, of the right sequence of keypresses for whatever function the technician needed.

This small keypad continues to build on the movie’s themes of systems that evolve: Wall-E is still controllable and serviceable by a human, but Eve from the very start has probably never even seen a human being. BNL has automated science to make it easier on their customers.

Mangalore Bomb

TheFifthElement-MangaloreBomb-005

Sadly for Zorg, just after he deactivates his bomb, a fallen Mangalore warrior remotely activates his own bomb in Plavalaguna’s suite. The remote control is made from a combination lock. The Mangalore twists the dial to the right numbers, and on reaching the last number, a red LED lights in the center. In the diva’s suite, the box that secretly housed the bomb opens, and the bomb rises like a small metallic ziggurat, accentuated in places with red LEDs. A red, 7-segment countdown timer begins ticking down its final 5 seconds.

Aggression

Mangalores are warlike, as in they really like war. They breathe war. They sleep war. They eat war for breakfast, then poop war, then root around in their couches for war scraps and snack on that. The detonation device isn’t very sophisticated, and that’s just fine by Mangalores. If a Mangalore declared a Design major instead of War in college, they’d have been killed on the spot. This device is perfect for a species that just wants to grab something cheap and convenient, make a few modifications, and get to the boom.

We don’t see a deactivation mechanism. And while you can imagine that a nice safety would be to deactivate if the dial drifted more than, say, 5 clicks from the final activation number, Mangalores wouldn’t have it. They’d “liberate” your mother’s homeland merely for having suggesting it.

If I had to improve it in any way, it’s that it places a burden on memory, and there’s not a lot of indication that Mangalores excel in the thinking skills department, c.f. warlike. Do they have the capacity to memorize a series of numbers in order? And it is easy to recall the series in the middle of a war zone? If not, what would be better? They have their weapons with them nearly at all times, so how about a little glowing, red button on the forestock?

Ha. Joke’s on you, Mangalores. As we know from earlier in the movie, you couldn’t resist pressing it, long before you made it to ocean liners. I think if you’re that warlike and stupid, this would be best for everyone.

Zorg bomb

TheFifthElement-ZorgBomb-001

When Zorg believes he has recovered the sacred stones, he affixes a bomb to the door of Plavalaguna’s suite. The bomb is a little larger than a credit card, with a slot at the top for a key card to be dropped in. The front of the bomb houses all the buttons and lights. The bottom and top edges are rounded back.

The interface for the bomb is quite simple. Zorg presses three large, transparent buttons along the top in order from left to right to activate the bomb. These buttons glow bright red during the countdown. Below these buttons, four red LEDs blink in succession counting off quarter seconds. At the bottom of the display a 4-character, 7-segment timer counts down from the time set: 20 minutes. The device audibly ticks off each second as it passes.

timebomb

Activation

An (adhesive? magnetic?) backing lets Zorg simply place the bomb on the wall to affix it there. Zorg presses the three large buttons in order from left to right to activate it and start the countdown.

Activation analysis

The bomber is after simple activation, but also wants very much to avoid accidental activation. Pressing the buttons in order might happen accidentally, for example from a tire or foot rolling across it. Better would be to have the activation code something much less likely to happen accidentally, like 1-3-2 or 2-3-1.

There’s also a question of whether a bomber would put giant glowing lights, reflective yellow tape, or an audible tick on the bomb (LEDs, if you didn’t know, don’t come with a ticking sound built in.) Each of these draws attention to the bomb, giving helpless victims time to evacuate, alert the authorities, or inform any explosive ordnance disposal personnel that happen to be wandering by. Yes, Zorg wants the bomb to explode, but only after a certain time, so he can get away. He should affix the bomb in some hidden place and design it with a less attention-getting display to suit his fiendish goals.

TheFifthElement-ZorgBomb-003

Deactivation

Once Zorg realizes that the box he stole was empty, he returns to the Fhloston Paradise liner to look for the stones. His first task is to deactivate the bomb. To do this he pulls out a keycard, and gingerly holds it above the bomb. His caution and nervousness implies that it has a jostle-sensitive anti-handling sensors, and that if he bumped it, it would go off. Fortunately for him, he manages to slip the card in without jostling the bomb, and sure enough, it stops with five seconds to go.

TheFifthElement-ZorgBomb-006

Deactivation analysis

The keycard is a mostly-smart deactivation strategy. As we can see, Zorg is quite nervous during the deactivation, and in such high-stress times, it’s better to rely on an object than a stressed villain’s memory for something like a password. The card is thin like a credit card and can fit in a wallet, so it’s easy to carry around. There’s a risk that the card could be misplaced, but the importance of the key will ensure that Zorg will keep track of it. There’s a risk it could be ruined and become useless, but we can presume Zorg made it with tough, ruggedized materials.

The problem with the shape is one of orientation. There are four ways a card can be oriented to a slot, and looking at the card, there is no clear indication of the correct one. The copper circuitry printed on both sides is asymmetrical, so it’s at least possible to tell the current orientation. Perhaps this is the “password” that the system requires, and the random stranger picking it up only has a one in four chance of getting it right.

Fortunately for Zorg, he remembers the correct orientation, and is able to stop the bomb.

Or, this bomb, anyway.

The Positronic Ray

Barbarella-136

To combat the Resistance uprising, Durand-Durand unleashes his dread Positronic Ray. To control it, he approaches a high backed chair and touches a spot on the back. The curved tip of the chair extends upwards a bit allowing him to sit down. As soon as he sits, the tip retracts to rest just above his head and the video panel slides close to him. The ray itself is mounted on a two-axis swivel just behind him, with the barrel pointing out of a horizontal window.

The interface consists of a complex array of transparent knobs mounted on a glowing flat panel, set beneath a large rectangular video screen. While he is using the weapon, we see his hands twiddling some of the shapes clockwise and counterclockwise.

Barbarella-139

The chair interface seems fine, if technically unnecessary, giving the gunner a small ritual feeling of power. The weapons interface, on the other hand, is a disaster. It has around 50 visible controls, none labeled for what they control or their extents, none have the slightest ergonomic consideration, and few are differentiated from the others in shape or placement. Also they’re all transparent, so add a lot of visual noise to the difficultly of use.

From his video screen we can tell that there are only a number of things to control: target (coupled to the camera), beam size (coupled to the camera zoom), and a trigger. Control for these simple variables could be accomplished with a joystick for targeting, a thumb button for triggering, and a slider at his left hand for zoom/beam size. Three controls which Durand-Durand could really think of as two.

Additionally, the screen only shows him what he’s currently focused on, failing to grant any of the field awareness that he’d need to keep the enemy at bay. Ultimately it’s a weapons interface that only a pacifist could love. Admittedly, he’s a mad engineer, and not a mad interaction designer, so maybe it’s just his insanity that explains this fiddly spread of extraneous controls with poor mapping and myopic feedback.

I’d love to credit this bad interface with saving the people of the city of SoGo, but unfortunately if its destruction hadn’t come from the Positronic Ray, it would have come from being swallowed by the Mathmos. Ultimately, they were doomed.

SoGo, destroyed

Helmet transition

Barbarella-008

The spherical helmet that Barbarella wears with her environmental suit can change from completely reflective to completely translucent. To do so she reaches with both hands and touches controls (never shown) on the back of the helmet to activate the transition. Over 40 seconds the reflectivity withdraws into the base of the helmet, revealing Barbarella’’s face through the glass.

Direct exposure to most of the electromagnetic spectrum is dangerous. To avoid Barbarella’s accidentally frying her own head in space, the suit must be designed against accidental activation. The strategy shown is called two-hand trip, which requires two hands to touch different controls at the same time to start the process. This is most often used in machines where you want hands out of the way of processes that could pinch or cut, but that aren’t dangerous after the process begins. In this case it’s less about mechanical danger than the risks with exposure.

Another strategy would be to use two-hand control, which would require constant contact during the transition. But since this transition is so slow (and presuming there is some undo mechanism that we never see) having this “two-hand trip” is not disastrous. If something or someone accidentally tripped it, she has more than enough time to recover.

On the other hand, 40 seconds is a long time for anyone to wait for things in the days of switchable glass. If your Barbarella was less dreamy-eyed & patient than this one, you might have to make a different tradeoff.
