And finally we come to the often-promised cyberspace search sequence, my favourite interface in the film. It starts at 36:30 and continues, with brief interruptions to the outside world, to 41:00. I’ll admit there are good reasons not to watch the entire film, but if you are interested in interface design, this will be five minutes well spent. Included here are the relevant clips, lightly edited to focus on the user interfaces.
Johnny and Jane have broken into a neighbourhood computer shop, which in 2021 will have virtual reality gear just as today even the smallest retailer has computer mice. Johnny clears miscellaneous parts off a table and then sits down, donning a headset and datagloves.
Headsets haven’t really changed much since 1995 when this film was made. Barring some breakthrough in neural interfaces, they remain the best way to block off the real world and immerse a user into the virtual world of the computer. It’s mildly confusing to a current day audience to hear Johnny ask for “eyephones”, which in 1995 was the name of a particular VR headset rather than the popular “iPhone” of today.Continue reading →
As mentioned, Johnny in the last phone conversation in the van is not talking to the person he thinks he is. The film reveals Takahashi at his desk, using his hand as if he were a sock puppeteer—but there is no puppet. His desk is emitting a grid of green light to track the movement of his hand and arm.
The Make It So chapter on gestural interfaces suggests Takahashi is using his hand to control the mouth movements of the avatar. I’d clarify this a bit. Lip synching by human animators is difficult even when not done in real time, and while it might be possible to control the upper lip with four fingers, one thumb is not enough to provide realistic motion of the lower lip.Continue reading →
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.
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 →
The hospital doesn’t have the equipment to decrypt and download the actual data. But Jane knows that the LoTeks can, so they drive to the ruined bridge that is the LoTek home base. As mentioned earlier under Door Bombs and Safety Catches the bridge guards nearly kill them due to a poorly designed defensive system. Once again Johnny is not impressed by the people who are supposed to help him.
When Johnny has calmed down, he is introduced to Jones, the LoTek codebreaker who decrypts corporate video broadcasts. Jones is a cyborg dolphin.Continue reading →
The second half of the film is all about retrieving the data from Johnny’s implant without the full set of access codes. Johnny needs to get the data downloaded soon or he will die from the “synaptic seepage” caused by squeezing 320G of data into a system with 160G capacity. The bad guys would prefer to remove his head and cryogenically freeze it, allowing them to take their time over retrieval.
1 of 3: Spider’s Scanners
The implant cable interface won’t allow access to the data without the codes. To bypass this protection requires three increasingly complicated brain scanners, two of them medical systems and the final a LoTek hacking device. Although the implant stores data, not human memories, all of these brain scanners work in the same way as the Non-invasive, “Reading from the brain” interfaces described in Chapter 7 of Make It So.
The first system is owned by Spider, a Newark body modification
specialist. Johnny sits in a chair, with an open metal framework
surrounding his head. There’s a bright strobing light, switching on
and off several times a second.
Nearby a monitor shows a large rotating image of his head and skull, and three smaller images on the left labelled as Scans 1 to 3. Continue reading →
In Johnny Mnemonic we see two different types of binoculars with augmented reality overlays and other enhancements: Yakuz-oculars, and LoTek-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.)Continue reading →
Later, in the brain hacking scene, we’ll hear two more sentences spoken.
Completionists: There’s also extensive use of voice output during a cyberspace search sequence, but there Johnny is wearing a headset so he is the only one who can hear it. That is sufficiently different to be left out of this discussion.
Voice is public
Sonic output in general and voice in particular have the advantage of being omnidirectional, so the user does not need to pay visual attention to the device, and, depending on volume and ambient noise, can be understood at much greater distances than a screen can be read. These same qualities are not so desirable if the user would prefer to keep the message or information private. We can’t tell whether these systems can detect the presence or absence of people, but the hotel message centre only spoke when Johnny was alone. Later in the film we will see two medical systems that don’t talk at all. This is most likely deliberate because few patients would appreciate their symptoms being broadcast to all and sundry.
Unless you’re the only one in the room
The bathroom tap is interesting because the temperature message was in English. This is a Beijing hotel, and the scientists who booked the suite are Vietnamese, so why? It’s not because we the audience need to know this particular detail. But we do have one clue: Johnny cursed rather loudly once he was inside the bathroom. I suggest that there is a hotel computer monitoring the languages being used by guests within the room and adjusting voice outputs to match. Current day word processors, web browsers, and search engines can recognise the language of typed text input and load the matching spellcheck dictionaries, so it’s a fair bet that by 2021 our computers will be able to do the same for speech.
After fleeing the Yakuza in the hotel, Johnny arrives in the Free City of Newark, and has to go through immigration control. This process appears to be entirely automated, starting with an electronic passport reader.
Once Johnny has installed his motion detector on the door, the brain upload can begin.
3. Building it
Johnny starts by opening his briefcase and removing various components, which he connects together into the complete upload system. Some of the parts are disguised, and the whole sequence is similar to an assassin in a thriller film assembling a gun out of harmless looking pieces.
It looks strange today to see a computer system with so many external devices connected by cables. We’ve become accustomed to one piece computing devices with integrated functionality, and keyboards, mice, cameras, printers, and headphones that connect wirelessly.
Cables and other connections are not always considered as interfaces, but “all parts of a thing which enable its use” is the definition according to Chris. In the early to mid 1990s most computer user were well aware of the potential for confusion and frustration in such interfaces. A personal computer could have connections to monitor, keyboard, mouse, modem, CD drive, and joystick – and every single device would use a different type of cable. USB, while not perfect, is one of the greatest ever improvements in user interfaces.Continue reading →
Johnny, with newly upgraded memory, goes straight to the hotel room where he meets the client’s scientists. Before the data upload, he quickly installs a motion detector on the hotel suite door. This is a black box that he carries clipped to his belt. He uses his thumb to activate it as he takes hold and two glowing red status lights appear.
Once placed on the door, there is just one glowing light. We don’t see exactly how Johnny controls the device, but for something this simple just one touch button would be sufficient.
A little later, after the brain upload (discussed in the next post), the motion detector goes off when four heavily armed Yakuza arrive outside the door. The single light starts blinking, and there’s a high pitched beep similar to a smoke alarm, but quieter.Continue reading →
