Johnny finds he needs a favor from a friend in cyberspace. We see Johnny type something on his virtual keyboard, then selects from a pull down menu.
A quick break in the action: In this shot we are looking at the real world, not the virtual, and I want to mention how clear and well-defined all the physical actions by actor Keanu Reeves are. I very much doubt that the headset he is wearing actually worked, so he is doing this without being able to see anything.
Will regular users of virtual reality systems be this precise with their gestures? Datagloves have always been expensive and rare, making studies difficult. But several systems offer submillimeter gestural tracking nowadays: version 2 of Microsoft Kinect, Google’s Soli, and Leap Motion are a few, and much cheaper and less fragile than a dataglove. Using any of these for regular desktop application tasks rather than games would be an interesting experiment.
Back in the film, Johnny flies through cyberspace until he finds the bulletin board of his friend. It is an unfriendly glowing shape that Johnny tries to expand or unfold without success.
When Theo, Kee, and Miriam flee the murderous Fishes, they take refuge in Jasper’s home for the night. They are awoken in the morning by Jasper’s sentry system.
A loud cacophonous alarm sounds, made up of what sounds like recorded dog barks, bells clanging, and someone banging a stick on a metal trash can lid. Jasper explains to everyone in the house that “It’s the alarm! Someone’s breaking in!”
They gather around a computer screen with large speakers on either side. The screen shows four video feeds labeled ROAD A, FOREST A, FRONT DOOR, and ROAD B. Labels reading MOTION DETECTED <> blink at the bottom of the ROAD A and ROAD B feeds, where we can see members of the Fishes removing the brush that hides the driveway to Jasper’s house.

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.Continue reading →
After selecting its location from a map, Johnny is now in front of the virtual entrance to the hotel. The virtual Beijing has a new color scheme, mostly orange with some red.
The “entrance” is another tetrahedral shape made from geometric blocks. It is actually another numeric keypad. Johnny taps the blocks to enter a sequence of numbers.
The tetrahedral keypad
Note that there can be more than one digit within a block. I mentioned earlier that it can be difficult to “press” with precision in virtual reality due to the lack of tactile feedback. Looking closely, here the fingers of Johnny’s “hands” cast a shadow on the pyramid, making depth perception easier.Continue reading →
The miniseries represents the best that the reboot has to offer. Its story is contained, the characters fill their roles, and it doesn’t overstay its welcome. The miniseries even ends on a solid cliffhanger: Will humanity survive?
Battlestar Galactica also picked a rarely chosen theme for its run. The well-used and anachronistic technology was in direct opposition to the Star Wars Prequels being released at the time. After getting my feet wet with my previous reviews, this was an entertaining choice because of its difficulty, detail, and setting.
I was constantly reminded during the review process that this miniseries represented—and this can’t be stated strongly enough—the end of human civilization.
Perhaps the most unusual interface in the film is a game seen when Theo visits his cousin Nigel for a meal and to ask for a favor. Nigel’s son Alex sits at the table silent and distant, his attention on a strange game that it’s designer, Mark Coleran, tells me is called “Kubris,” a 3D hybrid of Tetris and Rubik’s Cube.
Alex operates the game by twitching and sliding his fingers in the air. With each twitch a small twang is heard. He suspends his hand a bit above the table to have room. His finger movements are tracked by thin black wires that extend from small plastic discs at his fingertips back to a device worn on his wrist. This device looks like a streamlined digital watch, but where the face of a clock would be are a set of multicolored LEDs arranged in rows. These LEDs flicker on and off in inscrutable patterns, but clearly showing some state of the game. There is an inset LED block that also displays an increasing score. Continue reading →
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.
