The transition from Beijing to the Newark copyshop is more involved. After he travels around a bit, he realizes he needs to be looking back in Newark. He “rewinds” using a pull gesture and sees the copyshop’s pyramid. First there is a predominantly blue window that unfolds as if it were paper.
And then the copyshop initial window expands. Like the Beijing hotel, this is a floor plan view, but unlike the hotel it stays two dimensional. It appears that cyberspace works like the current world wide web, with individual servers for each location that can choose what appearance to present to visitors.
Johnny again selects data records, but not with a voice command. The first transition is a window that not only expands but spins as it does so, and makes a strange jump at the end from the centre to the upper left.
Once again Johnny uses the two-handed expansion gesture to see the table view of the records.
Johnny searches again, but either because there are so few records or because they’re in English, he doesn’t use voice commands. Instead he just runs his fingers over the cells, which highlight as he does so. Again this would be familiar to a current day spreadsheet user.
The contents of the cell are, once more, not useful. Johnny dismisses the copyshop with a sweeping arm gesture which slides the “window” off the right of the screen.
Aside: At normal viewing speed, it looks like the window disappears and, as would be the case in a 1995 or current day desktop system, reveals the previously-displayed windows underneath. Stepping through frame by frame shows that actually it reveals an identical copy of the sliding content! Graphics programmers have always tried hard to avoid such visual glitches, but sometimes they slip into production code anyway.

At this point in the plot, Johnny hasn’t found the images he so desperately needs. He thinks for a moment, and decides to contact the owner of a local bulletin board. Unknown to him, he has also been located by the Pharmakom tracker. Shinji and the Yakuza are on the way, and Shinji orders “initiate the virus.”
Cyberspace is usually considered to be a 3D spatial representation of the Internet, an expansion of the successful 2D desktop metaphor. The representation of cyberspace used in books such as Neuromancer and Snow Crash, and by the film Hackers released in the same year, is an abstract cityscape where buildings represent organisations or individual computers, and this what we see in Johnny Mnemonic. How does Johnny navigate through this virtual city?
Gestures and words for flying
Once everything is connected up, Johnny starts his journey with an unfolding gesture. He then points both fingers forward. From his point of view, he is flying through cyberspace. He then holds up both hands to stop.
Both these gestures were commonly used in the prototype VR systems of 1995. They do however conflict with the more common gestures for manipulating objects in volumetric projections that are described in Make It So chapter 5. It will be interesting to see which set of gestures is eventually adopted, or whether they can co-exist.
Later we will see Johnny turn and bank by moving his hands independently.
We also see him using voice commands, saying “hold it” to stop forward motion immediately. Later we see him stretch one arm out and bring it back, apparently reversing a recent move.
In cyberpunk and related fiction users fly everywhere in cyberspace, a literal interpretation of the spatial metaphor. This is also how users in our real world MUD and MOO cyberspaces start. After a while, travelling through all the intermediate locations between your start and destination gets tedious. MUDs and MOOs allow teleporting, a direct jump to the desired location, and the cyberspace in Johnny Mnemonic has a similar capability.
Gestures for teleporting
Mid sequence, Johnny wants to jump to the Beijing hotel where the upload took place. To do this, he uses a blue geometric shape at the lower left of his view, looking like a high tech, floating tetrahedron. Johnny slowly spins this virtual object using repeated flicking gestures with his left hand, with his ring and middle fingers held together.
It looks very similar to the gesture used on a current-day smartphone to flick through a photo album or set of application icon screens. And in this case, it causes a blue globe to float into view (see below).
Johnny grabs this globe and unfolds it into a fullscreen window, using the standard Hollywood two handed “spread” gesture described in Chapter 5 of Make It So.
The final world map fills the entire screen. Johnny uses his left hand to enter a number on a HUD style overlay keypad, then taps on the map to indicate China.
I interpret this as Johnny using the hotel phone number to specify his destination. It would not be unusual for there to be multiple hotels with the same name within a city such as Beijing, but the phone number should be unique. But since Johnny is currently in North America, he must also specify the international dialing code or 2021 equivalent, which he can do just by pointing. And this is a well-designed user interface which accepts not only multimodal input, but in any order, rather than forcing the user to enter the country code first.
Keyboards and similar physical devices often don’t translate well into virtual reality, because tactile feedback is non-existent. Even touch typists need the feeling of the physical keyboard, in particular the slight concavity of the key tops and the orientation bumps on the F and J keys, to keep their fingers aligned. Here though there is just a small grid of virtual numbers which doesn’t require extended typing. Otherwise this is a good design, allowing Johnny to type a precise number and just point to a larger target.

After he taps a location, the zoomrects indicate a transition into a new cyberspace, in this case, Beijing.
In Johnny Mnemonic we see two different types of binoculars with augmented reality overlays and other enhancements: Yakuz-oculars, and LoTek-oculars.
Yakuz-oculars
The Yakuza are the last to be seen but also the simpler of the two. They look just like a pair of current day binoculars, but this is the view when the leader surveys the LoTek bridge.
I assume that the characters here are Japanese? Anyone?
In the centre is a fixed-size green reticule. At the bottom right is what looks like the magnification factor. At the top left and bottom left are numbers, using Western digits, that change as the binoculars move. Without knowing what the labels are I can only guess that they could be azimuth and elevation angles, or distance and height to the centre of the reticule. (The latter implies some sort of rangefinder.)
So far, this is a simple uncluttered display. But why is there a brightly glowing Pharmakom logo at the top right? It blocks part of the view, and probably doesn’t help anyone trying to keep their eyes adapted for night vision.
LoTek-oculars
The LoTeks, despite their name, have more impressive binoculars. They’re first used when Johnny gets out of his airport taxi.
There’s a third tube above the optics, a rectangular inlet, and an antenna.
In these binoculars, the augmented reality overlay is much more dynamic. Instead of a fixed circle, green lines converge in a bounding box around the image of Johnny. Text slides onto the display from left to right, the last line turning yellow.
Zoomrect
The animated transition of the bounding box resembles what Classic MacOS programmers of the 1990s called “zoomrects” used for showing windows opening or closing. It’s a very effective technique to draw attention to a particular area of an image.
Animated text
Text appearing character by character is ubiquitous in film interfaces. In the 1960s and 1970s mainframe and minicomputer terminals really did display incrementally, as the characters arrived one by one over slow serial port links. On any more recent computer it actually takes extra programming to achieve this effect, as the normal display of text is so fast that we would perceive it as instantaneous. But people like to see incremental text, or have been conditioned by film to expect it, so why not?
Bioscanning
The binoculars detect Johnny’s implant. It might just be possible to detect this passively from infrared or electronic signals, but more likely the binoculars include a high resolution microwave radar as well. If there had been more than one person in view, the bounding box would indicate which one the text refers to. And note that the last line of text is a different color. What that means is unclear here, but it becomes clear (and I’ll discuss it) later.
The second time we see the LoTek binoculars is when a lookout spots Street Preacher, a very bad guy and another who wants to remove Johnny’s head. Once again the binoculars have performed more than just a visual scan.
The binocular view and overlay are being relayed to another character, the LoTek leader J-Bone who can watch on a monitor. Here the film anticipates the WiFi webcam.
The overlay text now changes.
Narrow AI?
This is interesting, because the binoculars can not only detect implants and other cyborg modifications, but are apparently able to evaluate and offer advice. It appears that the green text is used for the factual (more or less) information about what has been detected, while yellow text is uncertain or or speculative.
Does this imply a general artificial intelligence? Not necessarily. This warning could be based solely on the detected signature, in the same way that current day military passive sonars and radar warning receivers can identify threats based on identifying characteristics of a received signal. In the world of Johnny Mnemonic it would make sense to assume that anyone with full custom biomechanics is extremely dangerous. Or, since Street Preacher is a resident rather than a stranger and already feared by others, his appearance and the warning could have been entered into a LoTek facial recognition database that the binocular system uses as a reference.
These textual overlays are an excellent interface, not interfering with normal vision and providing a fast and easy-to-understand analysis. But, the user must have faith that the computer analysis is accurate. There’s no reason given as to why any of the text is displayed. If Johnny was carrying an implant in his pocket instead of his brain, would the computer know the difference?
An alternative approach would be some kind of sensor fusion or false spectrum display, with the raw infrared or radar image overlaid over the visuals and the viewer responsible for interpreting the data. The problem with such systems is that our visual system didn’t evolve to interpret such imagery, so a lot of training and practice is required to be both fast and accurate. And the overlay itself interferes with our normal visual recognition and processing. If the computer can do a better job of deciphering the meaning of non-visual data, it should do so and summarise for the human viewer.
Further advantages of this interface are that even a novice sentry will benefit from the built-in scanning and threat analysis, and the wireless transmission ensures that the information is shared rather than being limited to the person on watch.
