Topography “Pups”

The “pups,” as low-grade sociopath and geologist Fifield calls them, are a set of spheres that float around and spatially map the surface contours of a given space in real-time.

To activate them, Fifield twists their hemispheres 90 degrees along their equator, and they begin to glow red along two red rings.

When held up for a few seconds, they rise to the vertical center of the space they are in, and begin to fly in different directions, shining laser in a coronal ring as they go.

In this way they scan the space and report what they detect of the internal topography back to the ship, where it is reconstructed in 3D in real time. The resulting volumetric map features not just the topography, but icons (yellow rotating diamonds with last initials above them) to represent the locations of individual scientists and of course the pups themselves.

The pups continue forward along the axis of a space until they find a door, at which they will wait until they are let inside. How they recognize doors in alien architecture is a mystery. But they must, or the first simple dead-end or burrow would render it inert.

The pups are simple, and for that they’re pretty cool. Activation by twist-and-lift is easy through the constraints of the environment suits, easy to remember, and quick to execute, but deliberate enough not to be performed accidentally. Unfortunately we never see how they are retreived, but it raises some interesting interaction design challenges.

Bridge VP: Mapping

The main interface on the bridge is the volumetric projection display. This device takes up the center of the bridge and is the size of a long billiards table. It serves multiple purposes for the crew. Its later use is to display the real-time map of the alien complex.

Map of the alien complex

The redshirt geologist named Chance in the landing party uses some nifty tools to initiate mapping of the alien complex. The information is sent from these floating sensors back to the ship, which displays the results in real time.

The display of this information is rich with a saturated-color, color-coded, edge-opacity style, leaving outer surfaces rendered in a gossamer cyan, and internal features rendered in an edge-lit green wireframe. In the area above the VP surface, other arbitrary rectangles of data can be summoned for particular tasks, including in-air volumetric keyboards. The flat base of the bridge VP is mirrored, which given the complex 3D nature of the information, causes a bit of visual confusion. (Am I seeing two diamonds reflected or four on two levels?)

Later in the film, Janek tells Ravel to modify the display; specifically, to “strip away the dome” and “isolate that area, bring it up.” He is even to enlarge and rotate the alien spaceship when they find it. Ravel does these modifications this through a touch screen panel at his station, though he routes the results to the “table.” We don’t see the controls in use so can’t evaluate them. But being able to modify displays are one of the ways that people look for patterns and make sense of such information.

A major question about this interface is why this information is not routed back to the people who can use it the most, i.e. the landing party. Chance has to speak to Janek over their intercom and figure out his cardinal directions in one scene. I know they’re redshirts, but they’re already wearing high tech spacesuits. And in the image below we see that this diegesis has handheld volumetric projections. They couldn’t integrate one of those to a sleeve to help life-critical wayfinding?

Security and Control’s control

The mission is world-critical, so like a cockpit, the two who are ultimately in control are kept secure. The control room is accessible (to mere humans, anyway) only through a vault door with an armed guard. Hadley and Sitterson must present IDs to the guard before he grants them access.

Sitterson and Hadley pass security.

Truman, the guard, takes and swipes their cards through a groove in a hand-held device. We are not shown what is on the tiny screen, but we do hear the device’s quick chirps to confirm the positive identity. That sound means that Truman’s eyes aren’t tied to the screen. He can listen for confirmation and monitor the people in front of him for any sign of nervousness or subterfuge.

Hadley boots up the control room screens.

The room itself tells a rich story through its interfaces alone. The wooden panels at the back access Bronze Age technology with its wooden-handled gears, glass bowls, and mechanical devices that smash vials of blood. The massive panel at which they sit is full of Space Age pushbuttons, rheostats, and levers. On the walls behind them are banks of CRT screens. These are augmented with Digital Age, massive, flat panel displays and touch panel screens within easy reach on the console. This is a system that has grown and evolved for eons, with layers of technology that add up to a tangled but functional means of surveillance and control.

The interfaces hint at the great age of the operation.

Utter surveillance

In order for Control to do their job, they have to keep tabs on the victims at all times, even long before the event: Are the sacrifices conforming to archetype? Do they have a reason to head to the cabin?

The nest empties.

To these ends, there are field agents in the world reporting back by earpiece, and everything about the cabin is wired for video and audio: The rooms, the surrounding woods, even the nearby lake.

Once the ritual sacrifice begins, they have to keep an even tighter surveillance: Are they behaving according to trope? Do they realize the dark truth? Is the Virgin suffering but safe? A lot of the technology seen in the control room is dedicated to this core function of monitoring.

The stage managers monitor the victims.

There are huge screens at the front of the room. There are manual controls for these screens on the big panel. There is an array of CRTs on the far right.

The small digital screens can display anything, but a mode we often see is a split in quarters, showing four cameras in the area of the stage. For example, all the cameras fixed on the rooms are on one screen. This provides a very useful peripheral signal in Sitterson and Hadley’s visual field. As they monitor the scenario, motion will catch their eyes. If that motion is not on a monitor they expect it to be, they can check what’s happening quickly by turning their head and fixating. This helps keep them tightly attuned to what’s happening in the different areas on “stage.”

For internal security, the entire complex is also wired for video, including the holding cages for the nightmare monsters.

Sitterson looks for the escapees amongst the cubes.

The control room watches the bloody chaos spread.

One screen that kind of confuses us appears to be biometrics of the victims. Are the victims implanted with devices for measuring such things, or are sophisticated non-invasive environmental sensors involved? Regardless of the mechanisms, if Control has access to vital signs, how are they mistaken about Marty’s death? We only get a short glance at the screen, so maybe it’s not vital signs, but simple, static biometrics like height, and weight, even though the radiograph diagram suggests more.

Sitterson tries to avoid talking to Mordecai.

Communications

Sitterson and Hadley are managing a huge production. It involves departments as broad ranging as chemistry, maintenance, and demolitions. To coordinate and troubleshoot during the ritual, two other communications options are available beyond the monitors; land phone lines and direct-connection, push-to-talk microphones.

Hadley receives some bad news.
