Alien head stem line

Using a tool that looks suspiciously identical to the Injection Carbon Reader, the stem line provides electrical current to nerve endings. It is inserted directly into the alien head and then controlled wirelessly via unseen controls on a nearby touch-sensitive slate pad.

The output on the stem line device animates with changes, but it seems the numbers appear near the middle and then slide to fixed positions on the top and bottom. If the point of the display was output, and it is meant to be seen from a distance, wouldn’t a simpler large-number display make more sense? If motion is meant to convey the meaning, like a digital gauge on a multimeter, then the text should be fixed on the graduated background and slide with it.

By stimulating the locus coeruleus of the alien, the Prometheus scientists seek to “trick it into thinking it’s still alive,” even though they have not confirmed the physiology of this 2000 year old alien specimen, or even that (in a quick Googling, the author learned that) this is the panic area of the nervous system. Were the results really that surprising?

HYP.SL

The android David tends to the ship and the hypersleping crew during the two-year journey.

The first part of the interface for checking in on the crew is a cyan-blue touch screen labeled “HYP.SL” in the upper left hand corner. The bulk of this screen is taken up with three bands of waveforms. A “pulse” of magnification flows across the moving waveforms from left to right every second or so, but its meaning is unclear. Each waveform appears to show a great deal of data, being two dozen or so similar waveforms overlaid onto a single graph. (Careful observers will note that these bear a striking resemblance to the green plasma-arc alien interface seen later in the film, and so their appearance may have been driven stylistically.)

HYP.SL

To the right of each waveform is a medium-sized number (in Eurostile) indicating the current state of the index. They are color-coded for easy differentiation. In contrast, the lines making up the waveform are undifferentiated, so it’s hard to tell if the graph shows multiple data points plotted to a single graph, or a single datapoint across multiple times. Whatever the case, the more complex graph would make identifying a recent trend more complicated. If it’s useful to summarize the information with a single number on the right, it would be good to show what’s happening to that single number across the length of the graph. Otherwise, you’re pushing that trendspotting off to the user’s short term memory and risking missing opportunities for preventative measures.

Another, small diagram in the lower left is a force-directed, circular edge bundling diagram, but as this and the other controls on the screen are inscrutable, we cannot evaluate their usefulness in context.

After observing the screen for a few seconds, David touches the middle of the screen, a wave of distortion spreads from his finger for a half a second, and we hear a “fuzz” sound. The purpose of the touch is unclear. Since it makes no discernable change in the interface, it could be what I’ve called one free interaction, but this seems unlikely since such cinematic attention was given to it. My only other guess is to register David’s presence there like a guard tour patrol system or watchclock that ensures he’s doing his rounds.
