Door Bomb and Safety Catches

Johnny leaves the airport by taxi, ending up in a disreputable part of town. During his ride we see another video phone call with a different interface, and the first brief appearance of some high tech binoculars. I’ll return to these later, for the moment skipping ahead to the last of the relatively simple and single-use physical gadgets.

Johnny finds the people he is supposed to meet in a deserted building but, as events are not proceeding as planned, he attaches another black box with glowing red status light to the outside of the door as he enters. Although it looks like the motion detector we saw earlier, this is a bomb.

This is indeed a very bad neighbourhood of Newark. Inside are the same Yakuza from Beijing, who plan to remove Johnny’s head. There is a brief fight, which ends when Johnny uses his watch to detonate the bomb. It isn’t clear whether he pushes or rotates some control, but it is a single quick action. Continue reading

Brain Upload

Once Johnny has installed his motion detector on the door, the brain upload can begin.

3. Building it

Johnny starts by opening his briefcase and removing various components, which he connects together into the complete upload system. Some of the parts are disguised, and the whole sequence is similar to an assassin in a thriller film assembling a gun out of harmless looking pieces.

It looks strange today to see a computer system with so many external devices connected by cables. We’ve become accustomed to one piece computing devices with integrated functionality, and keyboards, mice, cameras, printers, and headphones that connect wirelessly.

Cables and other connections are not always considered as interfaces, but “all parts of a thing which enable its use” is the definition according to Chris. In the early to mid 1990s most computer user were well aware of the potential for confusion and frustration in such interfaces. A personal computer could have connections to monitor, keyboard, mouse, modem, CD drive, and joystick – and every single device would use a different type of cable. USB, while not perfect, is one of the greatest ever improvements in user interfaces. Continue reading

Red Phone

After the gravitic distortion is discovered, Barcalow flips a toggle switch upwards with his thumb. As Ibanez confirms that “Gravity is 225 and rising,” the light on the bridge turns red, and Barcalow turns to a monitor.

The monitor (seen above) features a video window in the top center. Along the left side of the screen 11 random numbers report the COMM STATS INTERSHIP. Along the right side of the screen 11 other random numbers report the COMM STATS INTRASHIP. Beneath the video some purple bars slide in and out from a central column of red rectangles. One of these rectangles is bright yellow. Beneath that a section reports SCANNING FREQUENCIES as 21 three-character strings, some of which are highlighted as red. At the bottom of the screen blue and yellow-green smears race back and forth across a rectangle. Everything is in Starship Troopers‘ signature saturated colors and a block font like Microgramma or Eurostile.

These details are almost immediately obscured, as Deladier looks up from her laptop (looking presciently like a modern Macbook Air with its aluminum casing) to look at the video monitor to demand a “Report,” and the video grows larger to fill the screen.

Here the snarky description must pause for some analysis.

Analysis

The red alert mechanism is actually pretty good. Both the placement of its switch at shoulder level and the fact that it must be flipped up help prevent against accidental activation. The fact that it’s a toggle switch means it can be undone with ease if necessary. The red light immediately provides feedback to everyone on the bridge (and throughout the ship?) that the system has gone into a red alert. No other action is necessary to alert the person who needs to be informed, i.e. the Captain. The only other improvement might be a klaxon warning to alert others who are sleeping, but it’s entirely possible that very thing is happening elsewhere on the ship, and the bridge is spared that distraction. So full marks.

The user interface on the monitor seems pretty crappy though. If someone is meant to monitor COMM STATS—intership or intraship—I cannot imagine how a column of undifferentiated numbers helps. A waveform would be more useful to track activity across a spectrum. Something. Anything other than a stack of numbers that are hard to read and interpret.

The SCANNING FREQUENCIES is similarly useless. Sure, it’s clear that the ship’s systems are scanning those frequencies, but the three-character strings require crew to memorize what those mean. If those frequencies are defined—as you imagine they must be to be at all useful as static variables—then you can remove the cognitive weight of having to memorize the differences between JL5 and LQ7 by giving them actual names, and only displaying the ones that have activity on them, and what that activity means. Does someone need to listen in? Shouldn’t that task be apparent? And why would that need to be shown generally to the bridge, rather than to a communications officer? And I’m not sure what those purple squiggles mean. It’s nice that they’re animated I guess, but if they’re meant to help the user monitor some variable, they’re too limited. Like the sickbay display on the original Star Trek, knowing the current state is likely not as useful as knowing how the information is trending over time. (See page 261 for more details on this.) So trendlines would be better here. The little sweeping candy colored smears are actually okay, though, presuming that it’s showing that the system is successfully sweeping all frequencies for additional signal. Perhaps a bit distracting, but easy to habituate.

It’s nice that the video screen fills the screen to match the needs of the communicators. But as with so many other sci-fi video calls, no effort is made to explain where the camera is on this thing. Somehow they can just look at the eyes of the other person on the monitor, and it works. This feels natural to the actors, looks natural to the audience, and would be natural in real life, but until we can figure out how to embed a camera within a screen, this can’t work this way, and we’re stuck with the gaze monitoring problem raised in the Volumetric Projection chapter of the book with the Darth Vader example.

So, all in all, this interface is mostly terrible until it becomes just a videophone. And even then there are questions.

Snarky description continues

Picking up the description where I left off, after the Captain demands a report, Barcalow tells her quickly “Captain, we’re in the path of an unidentified object heading toward us at high speed.” Ibanez then looks down at her monitor at the gravity well animation, to remark that the “Profile suggests an asteroid, ma’am.” You know, just before looking out the window.

Honestly, that’s one of the funniest two-second sequences in the whole movie.
