Jumping back in the film a bit, we’re going to visit the Ministry of Art. When Theo goes there to visit his brother, after the car pulls to the front of the secured building, Theo steps out and walks toward a metal-detector gate.
Its quite high, about 3 meters tall. The height helps to reinforce the notion that this is a public space.
This principle, that short ceilings are personal, and high ceilings are public, is I believe a well-established one in architectural design. Read the Alexandrian pattern if you’d like to read more about it.
Is it a public space? It is, since it’s a Ministry. But it isn’t, since he joins his brother in what looks like a rich person’s private dining room. I was always a bit confused by what this place was meant to be. Perhaps owning to The Dark Times, Nigel has cited Minister rights and cordoned off part of the Tate Modern to live in. If anyone can explain this, please speak up.
On the downside, the height makes the text more out of sight and harder to read by the people meant to be reading it.
The distance is balanced by the motion graphics of the translucent sign atop the gate. Animated red graphics point the direction of ingress, show a security stripe pattern, and provide text instructions.
Motion is a very strong attention-getting signal, and combined with the red colors, does all the attention-getting that the height risks. But even that’s not a critical issue, as there is of course a guard standing by to ensure his understanding and compliance.
Note that there is no interaction here (which is the usual filter for this blog), but since I’m publishing an interview with the designer of this and the Kubris interface soon, I thought I’d give it a quick nod.
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 date overlays the upper right hand corner of the screen, 06-DEC-2027, 08:10:58.
Across the bottom is a control panel of white numbers and icons on red backgrounds.
A radio button control for the number of video feeds to be displayed. Though we are seeing the 4-up display, the icon does not appear to be different than the rest.
16 enumerated icons, the purpose for which is unclear.
Video control icons for reverse, stop, play, and fast forward.
Three buttons with gray backgrounds and icons.
A wide button blinking MASTER ALARM
The scene cuts to Jasper’s rushing to the car outside the home, where none of the cacophony can be heard.
Similar to his car dashoard, it makes sense that Jasper has made this alarm himself. This might explain the clunky layout and somewhat inscrutable icons. (What do the numbers do? What about that flower on the gray background?)
The three jobs of an intruder alarm
Jasper’s alarm is OK. It certainly does the job of grabbing the household’s attention, which is the first job of an alarm, and does it without alerting the intruders, as we see in the shot outside the house.
It could do a bit better at the second job of an alarm, which is to inform the household of the nature of the problem. That they have to gather around the monitor takes precious time that could be used for making themselves safer. It could be improved by removing this requirement.
If Jasper had added more information to the audio alarm, even so basic as a prerecorded “Motion on the road! Motion on the road!” then they might not have needed to gather around the monitor at all.
If the relevant video feeds could be piped to wearable devices, phones, or their car, then they can fill in their understanding at the same time that they are taking steps to getting the hell out of there.
Having the artificial intelligence that we have in actual-world 2017 (much less speculative 2027), we know that narrow AI can process that video to have many more details in the broadcast message. “Motion on the road! I see three cars and at least a dozen armed men!”
There is arguably a third job of an advanced alarm, and this is to help the household understand the best course of action. This can be problematic when the confidence of the recommendation is low. But if the AI can confidently make a recommendation, it can use whatever actuators it has to help them along their way.
It could be informational, such as describing the best option. The audio alarm could encourage them to “Take the back road!” It could even alert the police (though in the world of Children of Men, Jasper would not trust them and they may be disinclined to care.)
The alarm could give some parameters and best-practice recommendations like, “You have 10 minutes to be in the car! Save only yourselves, carry nothing!”
It could keep updating the situation and the countdown so the household does not have to monitor it.
It can physically help as best it can, like remotely starting and positioning cars for them.
This can get conceptually tricky as the best course of action may be conditional, e.g. “If you can get to the car in 5 minutes, then escape is your best option, but if it takes longer or you have defenses, then securing the home and alerting the police is the better bet.” But that may be too much to process in the moment, and for a household that does not rehearse response scenarios, the simpler instruction may be safer.
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 →
In a very brief scene, Theo walks through a security arch on his way into the Ministry of Energy. After waiting in queue, he walks towards a rectangular archway. At his approach, two horizontal green laser lines scan him from head to toe. Theo passes through the arch with no trouble.
Though the archway is quite similar to metal detection technology used in airports today, the addition of the lasers hints at additional data being gathered, such as surface mapping for a face-matching algorithm.
We know that security mostly cares about what’s hidden under clothes or within bodies and bags, rather than confirming the surface that security guards can see, so it’s not likely to be an actual technological requirement of the scan. Rather it is a visual reminder to participants and onlookers that the scan is in progress, and moreover that this the Ministry is a secured space.
Though we could argue that the signal could be made more visible, laser light is very eye catching and human eyes are most sensitive at 555nm, and this bright green is the closest to the 808 diode laser at 532nm. So for being an economic, but eye catching signal, this green laser is a perfect choice.
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 →
Johnny leaves the airport by taxi, ending up in a disreputable part of town. During his ride we see another video phone call with a different interface, and the first brief appearance of some high tech binoculars. I’ll return to these later, for the moment skipping ahead to the last of the relatively simple and single-use physical gadgets.
Johnny finds the people he is supposed to meet in a deserted building but, as events are not proceeding as planned, he attaches another black box with glowing red status light to the outside of the door as he enters. Although it looks like the motion detector we saw earlier, this is a bomb.
This is indeed a very bad neighbourhood of Newark. Inside are the same Yakuza from Beijing, who plan to remove Johnny’s head. There is a brief fight, which ends when Johnny uses his watch to detonate the bomb. It isn’t clear whether he pushes or rotates some control, but it is a single quick action.Continue reading →
After ditching Chewie, Boba Fett heads to a public video phone to make a quick report to his boss who turns out to be…Darth Vader (this was a time long before the Expanded Universe/Legends, so there was really only one villain to choose from).
To make the call, he approaches an alcove off an alley. The alcove has a screen with an orange bezel, and a small panel below it with a 12-key number panel to the left, a speaker, and a vertical slot. Below that is a set of three phone books. For our young readers, phone books are an ancient technology in which telephone numbers were printed in massive books, and copies kept at every public phone for reference by a caller.
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 →
