Jasper’s Music Player


After Jasper tells a white lie to Theo, Miriam, and Kee to get them to escape the advancing gang of Fishes, he returns indoors. To set a mood, he picks up a remote control and presses a button on it while pointing it at a display.


He watches a small transparent square that rests atop some things in a nook. (It’s that decimeter-square, purplish thing on the left of the image, just under the lampshade.) The display initially shows an album queue, with thumbnails of the album covers and two bright words, unreadably small. In response to his button press, the thumbnail for Franco Battiato’s album FLEURs slides from the right to the left. A full song list for the album appears beneath the thumbnail. Then track two, the cover of Ruby Tuesday, begins to play. A small thumbnail to the right of the album cover appears, featuring some white text on a dark background and a cycling, animated border. Theo puts the remote control down, picks up the Quietus box, and walks over to Janice. *sniff*

This small bit of speculative consumer electronics gets around 17 seconds of screen time, but we see enough to consider the design.  Continue reading

Video Phone Calls

The characters in Johnny Mnemonic make quite a few video phone calls throughout the film, enough to be grouped in their own section on interfaces.

The first thing a modern viewer will note is that only one of the phones resembles a current day handheld mobile. This looks very strange today and it’s hard to imagine why we would ever give up our beloved iPhones and Androids. I’ll just observe that accurately predicting the future is difficult (and not really the point) and move on.

More interesting is the variety of phones used. In films from the 1950s to the 1990s, everyone uses a desk phone with a handset. (For younger readers: that is the piece you picked up and held next to your ear and mouth. There’s probably one in your parents’ house.) The only changes were the gradual replacement of rotary dials by keypads, and some cordless handsets. In 21st century films everyone uses a small sleek handheld box. But in Johnny Mnemonic every phone call uses a different interface.

New Darwin

First is the phone call Johnny makes from the New Darwin hotel.


As previously discussed, Johnny is lying in bed using a remote control to select numbers on the onscreen keypad. He is facing a large wall mounted TV/display screen, with what looks like a camera at the top. The camera is realistic but unusual: as Chapter 10 of Make It So notes, films very rarely show the cameras used in visual communication. Continue reading

Hotel Remote

The Internet 2021 shot that begins the film ends in a hotel suite, where it wakes up lead character Johnny. This is where we see the first real interface in the film. It’s also where this discussion gets more complicated.

A note on my review strategy

As a 3D graphics enthusiast, I’d be happy just to analyze the cyberspace scenes, but when you write for Sci Fi Interfaces, there is a strict rule that every interface in a film must be subjected to inspection. And there are a lot of interfaces in Johnny Mnemonic. (Curse your exhaustive standards, Chris!)

A purely chronological approach which would spend too much time looking at trees and not enough at the forest. So I’ll be jumping back and forth a bit, starting with the gadgets and interfaces that appear only once, then moving on to the recurring elements, variations on a style or idea that are repeated during the film.


The wakeup call arrives in the hotel room as a voice announcement—a sensible if obvious choice for someone who is asleep—and also as text on a wall screen, giving the date, time, and temperature. The voice is artificial sounding but pleasant rather than grating, letting you know that it’s a computer and not some hotel employee who let himself in. The wall display functions as both a passive television and an interactive computer monitor. Johnny picks up a small remote control to silence the wake up call.


This remote is a small black box like most current-day equivalents, but with a glowing red light at one end. At the time of writing blue lights and indicators are popular for consumer electronics, apparently following the preference set by science fiction films and noted in Make It So. Johnny Mnemonic is an outlier in using red lights, as we’ll see more of these as the film progresses. Here the glow might be some kind of infrared or laser beam that sends a signal, or it might simply indicate the right way to orient the control in the hand for the controls to make sense.

Scenery display

BttF_096Jennifer is amazed to find a window-sized video display in the future McFly house. When Lorraine arrives at the home, she picks up a remote to change the display. We don’t see it up close, but it looks like she presses a single button to change the scene from a sculpted garden to one of a beach sunset, a city scape, and a windswept mountaintop. It’s a simple interface, though perhaps more work than necessary.

We don’t know how many scenes are available, but having to click one button to cycle through all of them could get very frustrating if there’s more than say, three. Adding a selection ring around the button would allow the display to go from a selected scene to a menu from which the next one might be selected from amongst options.

Is serial presentation a problem in The Circuit?


In the prior post I described the wonky sex teleporter known as The Circuit and began a critique. Today I go deep into a particular issue to finish the critque.

We only see Logan encounter two riders when using The Circuit, but we can presume that there are a lot of people on there. Why does it only show Logan a single choice at a time? If he actually has, say, 12 candidates that are a match, a serial presentation like this puts a significant burden on his memory. Once he gets to #12 and thinks he’s seen enough candidates, was it #3 or #5 he liked best?

The serial presentation also looks like it might make extra work. If he gets to #12 and decides he was most fond of #2, does he have to jump back through 10 people to get there? What does he say to each of them in turn? Does he have to reject them each again? How awkward is that? If not, and he can jump back to #2, what’s the control for that? Does he have to remember what station they were on and retune them in again? Continue reading

The Circuit


One of my favorite interfaces in Logan’s Run is one of the worst in the survey. It’s called The Circuit, and it’s a system for teleporting partners for casual sex right into your living room. ZOMGEVERYBODYSIGNUP.

Credit where it’s due: I first explored this interface in Issue 04 of Raymond Cha’s awesome print zine FAQNP in 2012. I’m going to go into even more nerdly depth on some of the topics here, but it was in that publication that I first got riled up about it. If you want to read those thoughts, you’ll need to go find a back issue and you totally should because the whole zine rocks.

Anyway, this interface is such a hot, hot mess that I have to break it up into a couple of posts. This first one is a description and the first part of a critique. Continue reading



Amongst its many holdings (including taxi cab companies) Zorg industries manufactures weapons, including their flagship weapon, the ZF-1. It has a great many features. It stores as a sealed pod, and can be activated by a remote control. With a press of a button, shielding retracts and parts extend so it can be handled like a traditional small arms weapon.

Zorg makes a pitch to the Mangalores for the ZF-1, so we’ll just let his own words sell it.

It’s light. The handle is adjustable for easy carrying. Good for righties and lefties. Breaks down into four parts. Undetectable by x-ray. Ideal for quick, discreet interventions. A word on firepower: Titanium recharger. 3,000 round clip with liquid bursts of 3-to-300.”

Next he pitches something quite unique to the weapon.

“With the Replay™ button—another Zorg invention—it’s even easier. One shot…and Replay™ sends every following shot to the same location…”

As he turns and points the weapons at the Mangalores, the ammunition arcs around to home in on the first shot.


But wait, don’t answer. The ZF-1 has other features as well.

…And to finish the job, all the Zorg oldies but goldies: Rocket launcher, arrow launcher with explosive, poisonous gas heads (very practical), our famous net launcher, the always-efficient flamethrower (my favorite), and for the grand finale, the all-new Ice Cube™ System.

After the Magalores fail to uphold their end of the bargain, Zorg leaves them to play with the weapons. As they do, one discovers that the glowing red button on the side is actually an explosive self-destruct.



I know Mangaglores are not meant to be shining examples of intellect, but if I was considering a purchase, I would yes, compliment the incredibly nifty technology of Replay, but follow it up with four more important questions about the design of the thing.

First, Mr. Zorg, what good is the remote control? Doesn’t this make the weapon hackable remotely? Isn’t that device easy to misplace? What on-weapon means do we have to unlock it?

Second, how are you selecting from among the six different types of ammunition?


On the exterior, we only see that red button. There might be some other subtle switches somewhere on the exterior, but you had to support the weight of the device with your left hand, so it’s fairly immobilized and I didn’t see you moving it. Unless it can only fire in exactly the order we saw, there’s got to be some other control. With your right hand hidden up inside the weapon, there must be other activation switches there. What switches are tucked up in there that are easy to differentiate by touch and easy to activate with your palm remaining against the grip?

Third, there’s that red button. Sure, who wouldn’t want to carry around a device that could erupt as an all-consuming fireball, but I notice that it doesn’t have a safety cover on it, gives no pause or warning during which the command can be retracted, and draws attention to itself by its glow. Isn’t that going to be increadibly easy to, you know, accidentally kill all my troops?

Fourth, during the demonstration we got a good glimpse at the front of the weapon. It’s got animated, blinking red LEDs whose pattern merges together to form a bright red diamond shape near the top of the weapon before looping over again.


I’m not a militarily-minded person, but isn’t it counter to a soldier’s goals to have anything blinking, glowing, or pinpointing the soldier’s exact midline to enemies, much less something that does all three at once, and in red, the color that travels the farthest in atmosphere?

What was that about “discreet” interventions?

Roach Cam


To learn the plans of the President, Zorg’s flunky named Right Arm infiltrates the briefing room via a remote-controlled cockroach. This adorable insect has a small parabolic receiver antenna on its back. Right Arm can watch what it sees with its eyes and listen to what it can hear through its… cerci?


The screen he uses is mostly full of the roachcam video. But it is unfortunately surrounded by some screen-green sciencey nonsense. A row across the top is headed “001” with rectangles labeled “MOVE”, “METHOD”, “CHECK”, and “SYSTEM.” A row just below is headed “A-B” with rectangles labeled “SPEED”, “TIMER”, “EXIT”, and “FILTERS.” A column of screen-green nonsense shapes fills the left side. A small butterfly-shaped graph at the bottom-left is labeled “CHECK.” A small box labeled “CALCULATING” is in the lower middle, which occasionally fills with scrolling nonsense. The right side of the screen is full of a circular graph showing a seizure-inducing flashing pair of green concentric circles. A green 8×8 grid on the right stays empty the whole time, though it is arguably the most likely useful thing, i.e. an overhead view of threats, say, like presidents brandishing cockroach-smashing shoes. Below the unused grid is a diagram of the roach itself, probably useful for understanding the health of the vehicle. Below that is a bit of unintelligible text reversed out of a gray background. When the roach nears the President, a bit of green nonsense text appears overlaid on the video feed, though it never changes.

I think this screen would have been less distracting and more helpful for Right Arm if you stripped away all the gunk at the top, the nonsensical overlay, trashed the column of hastily-drawn icons, saved him the constant distraction of the seizure circle by removing it, and leaving him with the two things that would actually be useful: the map (populated of course with some useful information), and the roach health diagram. Even though this screen is seen only for a few seconds at most, it reads as if it was hastily put together, unlike most other things seen in the film.



He is able to control the roach’s movement by means of a joystick with a rotating head. In contrast to the screen, this provides exactly what Right Arm needs to control the roach, and no more. He can move it forward and back by pushing the joystick forward and back. He can have it strafe right or left by moving the joystick appropriately. And when he wants to have it turn right or left, he can twist the joystick head in that direction. Pushing or twisting farther results in more motion. All told, a perfect input control for the task at hand. At least until you ask the roach.
