Tattoo-o-matic

StarshipTroopers-Tattoo-01

After he is spurned by Carmen and her new beau in the station, Rico realizes that he belongs in the infantry and not the fleet where Carmen will be working. So, to cement this new identity, Rico decides to give in and join his fellow roughnecks in getting matching tattoos.  The tattoos show a skull over a shield and the words “Death from Above”. (Incidentally, Death From Above is the name of the documentary detailing the making of the film, a well as the title of a hilarious progressive metal video by the band Holy Light of Demons. You should totally check it out.) 

To get the tattoo, Johnny lies back in a chair, and a technician of some sort works briefly at waist-high controls beneath a nearby screen. Then the technician walks away while Johnny’s tattoo is burned with blue lasers onto his arm.

A man seated in a futuristic setting is receiving a tattoo from a robotic arm. The tattoo features the word 'DEATH' surrounded by a star emblem. A computer screen in the background displays various graphs and a logo related to the tattooing process.

At the upper left corner of the screen a display reads SELECTED above the image being burned into Rico’s arm. (With white indicating no color.) Beneath it, is a square divided into four quadrants is filled with unintelligible numbers scrolling along, above the words AUTOMATIC SEQUENCE CONTROL.  Down the center of the screen beneath the word LASERS is a column filled with boxes showing sine waves and their corresponding frequencies from the shorter blue wavelengths moving down to yellow, red, and finally a double-lined white waveform. At the right of the screen is a large screen-green rectangular grid on which the selected pattern wipes in from top to bottom as the corners blink in red and yellow.

There are two main problems that are apparent in the scene.

1. We don’t need the technician

What does the technician do? Essentially, he presses a button and then walks away. Even as Johnny’s friends rush him out of the room in celebration, no one stops them to pay, which seem to indicate that everything has already been taken care of before he sits in the chair. Also, we notice that Johnny’s arm has not been strapped down, wrapped in healing bandages, or secured in any way. He stays relatively still throughout the procedure, but it seems a safe assumption that not all customers will be stoic soldier types who are able to sit still while their arm is literally charred by lasers in front of their own eyes. The machine must be able to compensate for movement, either by adjusting the lasers or shutting off completely, so, again, no technician is necessary. Also, when a fellow roughneck pours liquor over Johnny’s arm while his skin is in the process of being vaporized by lasers, the liquor doesn’t ignite in a horrifying fireball as we might expect, indicating that the lasers must have scaled back their intensity just in the nick of time—this is a pretty context-aware system with a lot of built-in error correction. Maybe they’re there for insurance purposes but given what we see in the scene, they serve no real purpose. Assuming the Death from Above design was one already in the machine, he could have completed the entire transaction himself from start to liquor-soaked finish.

2. The screen doesn’t make sense

As the image of the selected design scans into view on the right side of the screen, we can see that there is no exact correlation between the parts of the image on screen, and the parts of the image on-skin. The wireframe wipes in from top-to-bottom. The tattoo is finishing up in the middle. The tattoo is already 90% complete when the animation begins. The blinking numbers, the wiggling sine waves. It doesn’t mean anything and isn’t useful. So all told, the information on the screen initially appears complex, but given the total automation of the system it’s actually quite simple: Here’s what’s happening, and here’s the progress.

But maybe it’s not for the technician

Maybe it’s not for the technician at all. You can imagine that while having your skin seared by painful, painful lasers, all that fuigetry would be a welcome distraction, and a progress bar would be a welcome reassurance that it won’t last forever. With this in mind, the main problem with the screen is that it should be facing the customer, who is the real user.

The Aesculaptor Mark III

LogansRun177

The device with which the cosmetic surgery is conducted is delightfully called the Aesculaptor Mark III. Doc brags that it is “the latest. It’s completely self-contained.

In it, the patient lies flat in a recess on a rounded table, the tilt and orientation of which is computer controlled. Above the table is a metallic sphere with six spidery articulated arms. Some of these house laser scalpels and some of these house healing sprays. The whole mechanism is contained in a cylinder of glass.

To control the system, Doc has a panel made up of unlabeled buttons and dials, a single blue monitor, and another panel displaying a random five-digit number and two levers. One is labeled “ANODYNE” and the other is labeled “KINESIS.”

When Doc receives a mysterious call (on what may be the earliest wireless telephone in mainstream science fiction,) he receives instructions to murder Logan. To do so he turns off the healing by moving the ANODYNE lever into the lower position.

So. Yeah. Also just terrible. I mean there’s the plot question. I ordinarily don’t drop into questions of plot, but come on. If Doc wanted to eliminate Logan, wouldn’t he increase the anodyne, so Logan wouldn’t know he was being killed until it was too late? If you wanted to torture him, wouldn’t you put him under a paralytic first, and only then turn off the anodyne? Turning on the KINESIS (moving lasers?) and turning off the anodyne just seem counter to his actual goals. Unless you want to fantheory this so that Doc’s instruction was “make him escape.”

But yes, back to the interface. There’s almost nowhere to start. Undifferentiated controls? Unlabeled controls? No visual hierarchy? Only the device itself and an oscilloscope to monitor the system and the patient’s trending state? Un-safeguarded knife switches for the primary controls? And note that the fail state is in the direction of gravity. If that knife switch gets loose, oops, you’re screwed.

Logan’s Run took place long before the lessons of the Therac-25, with its tragic interface and programming problems that resulted in the deaths of several cancer patients, but even audiences in 1976 would not believe that any medical device would have such an easy means of disabling the only aspect of it that keeps it from becoming an abattoir.

New You Selector

In addition to easy sex and drugs, citizens of Dome City who are either unhappy or even just bored with the way they look can stop by one of the New You salons for a fast, easy cosmetic alternation.

At the salon we get a glimpse of an interface a woman is using to select new facial features. She sits glancing down at a small screen on which she sees an image of her own face. A row of five unlabeled, gray buttons are mounted on the lower bevel of the screen. A black circle to the right of the screen seems to be a camera. She hears a soft male voice advising, “I recommend a more detailed study of our projections. There are new suggestions for your consideration.

She presses the fourth button, and the strip of image that includes her chin slides to the right, replaced with another strip of image with the chin changed. Immediately afterwards, the middle strip of the image slides left, replaced with different cheekbones.

In another scene, she considers a different shape of cheekbones by pressing the second button.

So. Yeah. Terrible.

  • The first is poor mapping of buttons to the areas of the face. It would make much more sense, if the design was constrained to such buttons, to place them vertically along the side of the screen such that each button was near to the facial feature it will change.
  • Labels would help as well, so she wouldn’t have to try buttons out to know what they do (though mapping would help that.)
  • Another problem is mapping of controls to functions. In one scene, one button press changes two options. Why aren’t these individual controls?
  • Additionally, if the patron is comparing options, having the serial presentation places a burden on her short term memory. Did she like the apple cheeks or the modest ones better? If she is making her decision based on her current face, it would be better to compare the options in questions side-by-side.
  • A frontal view isn’t the only way her new face would be seen. Why does she have to infer the 3D shape of the new face from the front view? She should be able to turn it to any arbitrary angle, or major viewing angles at once, or watch videos of her moving through life in shifting light and angle conditions, all with her new face on.
  • How many options for each component are there? A quick internet search showed, for noses, types show anything between 6 and 70. It’s not clear, and this might change how she makes her decision. If it’s 70, wouldn’t some subcategories or a wizard help her narrow down options?
  • Recovery. If she accidentally presses the wrong button, how does she go back? With no labeling and an odd number of buttons to consider, it’s unclear in the best case and she’s forced to cycle through them all in the worst.
  • The reason for the transition is unclear. Why not a jump cut? (Other than making sure the audience notices it.) Or a fade? Or some other transition.
  • Why isn’t it more goal-focused? What is her goal in changing her face? Like, can she elect to look more like a perticular person? Or what she thinks her current object of affection will like? (Psychologically quite dystopian.) Or have her face follow current face fashion trends? Or point out the parts of herself that she doesn’t like? Or randomize it, and just “try something new?”

OK I guess for both showing how easy cosmetic surgery is in the future, and how surface Dome City’s residents’ concepts of beauty are, this is OK. But for actual usability, a useless mess.
