Report Card: Johnny Mnemonic

There are no more interfaces within the film to analyse. But before moving on to the grades, some final (and brief – I promise) discussion about cyberpunk and virtual reality.

Read all Johnny Mnemonic reviews in chronological order.

Cyberpunk Love

As stated at the beginning, Johnny Mnemonic is a cyberpunk film, with the screenplay written by noted cyberpunk author William Gibson, loosely based on one of his short stories of the same name. Why would user interface designers care? Because the cyberpunk authors were the first to write extensively about personal computing technologies, world wide networks, 2D/3D GUIs, and AI. Cyberspace, both the idea and the word itself, comes from cyberpunk fiction. Just as Star Trek inspired NASA engineers and astronauts, the cyberspace depicted by the authors inspired virtual reality programmers and designers. In the first virtual reality wave of the mid to late 1990s, it seemed that everybody working in the field had read Neuromancer.

If you’ve never read any cyberpunk and are now curious, Neuromancer by William Gibson is still the classic work. For a visual interpretation, the most cyberpunk of all films, in style and tone rather than plot, is Blade Runner. Cyberpunk founder Bruce Sterling, who wrote the foreword for “Make It So”, often writes about design; and sometimes cyberpunk author Neal Stephenson has also written interesting and thought provoking non-fiction about computers and user experience. It’s beyond the scope of this post to outline all their ideas for you, but if you are interested start with:

In the Beginning was the Command Line

VR Love

Johnny Mnemonic also includes scenes set in virtual reality, a trend that began with Tron (although that particular film did not use the term). These virtual reality scenes with their colorful graphics  were most likely included to make computer systems less boring and more comprehensible to a general audience. However, these films from Tron onwards have never been successful. (If you work around computer people you’ll hear otherwise from plenty of fans, but computer geeks are not a representative sample.)

In the more recent Iron Man films, Tony Stark in his workshop uses a gestural interface, voice commands, and large volumetric projections. This could easily have been depicted as a VR system, but wasn’t. Could there be a usability problem when virtual reality interfaces are used in film?

The most common reason given for not using VR is that such sequences remind the audience that they’re watching an artificial experience, thus breaking suspension of disbelief. Evidence for this is the one financially successful VR film, The Matrix, which very carefully made its virtual reality identical to the real world. The lesson is that in film, just like most fields, user interfaces should not draw too much attention to themselves.

Cyberspace Summary

In the five minute sequence about cyberspace, we’ve seen a variety of interface elements and actions. The single most impressive quality of the Johnny Mnemonic cyberspace is, to me, just how flexible and multi-modal it is.

JM-38-cyberspace-montage

Cyberspace was envisioned as a 3D spatial metaphor. Here we’ve seen that with specialized hardware, you can fly with hand gestures or voice commands. Or if you’re in a hurry, you can teleport directly. Destinations can be specified precisely with numbers or graphically by pointing. Other actions can be expressed by pointing and other gestures, or by typing in text or numbers, or by speaking.

The primary output channel is obviously visual, but voice feedback is used to indicate successful actions rather than cluttering up the screen. The visual style at the top level of interaction is three dimensional, but internal systems use more conventional 2D interfaces when 3D would be confusing or excessive. Most “applications” run in what is currently called full screen mode, but there is some evidence that the user could have multiple systems appearing side by side in a kind of three-dimensional window manager.

It’s been two decades since Johnny Mnemonic was released, but the film version of cyberspace still looks like an interface that would be both fun and effective. (OK, replace the datagloves with modern motion capture cameras.) That’s quite a lot of staying power, and it’s still worth seeing the film for these five minutes alone.

(And now, finally, after writing far more words than I’d originally intended, there are no more interfaces left to analyze in the film. Roll credits in the Report Card, coming up next.)

Cyberspace: Bulletin Board

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.

Cyberspace: Newark Copyshop

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

Cyberspace: Beijing Hotel

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.

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

Cyberspace: Navigation

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.

jm-31-navigation-animated

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.

Phone System Analysis

Note to readers: The author and editor of this series of posts would like to be Matrix-style cool, competent, stylishly-dressed world-changers with superhuman abilities. In reality we are much closer to the protagonists of Johnny Mnemonic: always frantically improvising to stay one step ahead of disaster with a mix of clunky technology. (And we don’t even have a cybernetic dolphin helping out.) So, um, yeah. This post is out of order. Sorry. Please pretend you haven’t read Cyberspace: the Hardware yet. OK. On to an analysis of the phone system.

jm-22-1-phone-montage

The video phones in Johnny Mnemonic all seem easy to use and reliable, but this is generally true of all phones in film and TV, video or otherwise. The audience want to see the characters communicate, not struggle with technology – unless difficulty or failure is necessary for the plot! Continue reading
