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.
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:
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.
