Video Phone Calls

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.

New Darwin

First is the phone call Johnny makes from the New Darwin hotel.

jm-3-phone-hotel-c-adjusted

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.

Taxi

The second phone call takes place in Newark, as Johnny rides in a taxi from the airport. Since this is a moving vehicle rather than a room, it shows that wireless videophones also exist. We don’t see how the call is made, just the conversation. Johnny is looking at and speaking into a small screen in front of his seat.

jm-10-taxi-a-adjusted

Quick aside: The blue lines at the bottom of the screen are a street map, with the glowing dot being the taxi. While it’s not the focus of this particular interface, it’s interesting that this map seems to be fixed with the indicator moving sideways. Aircraft and now car navigators use a moving map with the indicator moving up for forward. But this is for the passenger rather than the driver so doesn’t need to be particularly useful. And it’s blue, so must be advanced.

At the other end is Ralphie, who is using a desk screen with a keyboard.

jm-10-taxi-b-adjusted

We get to see things from Ralphie’s end. His keyboard only has ten keys in two rows of five. Ralphie touches the middle key in the bottom row to end the call.

Is this a dedicated phone rather than a computer? The only full-sized keyboards we see in Johnny Mnemonic are part of systems implied to be outdated or salvaged. Perhaps by 2021 voice recognition is good enough to handle most input. Or perhaps by 2021 status indicators have changed and once again nobody who considers themselves important would have a QWERTY keyboard on their desk, leaving others to do the more “menial” typing.

Shinji’s mobile

There is a cyberspace sequence (discussed in a separate post) during which there is a conversation between a Pharmakom tracker and Shinji, the leader of the Yakuza searching for Johnny, who is in en route by car. Shinji’s phone seems to be just like a current day mobile, if perhaps a little smaller than we’re used to.

Takahashi’s desk phone

Takahashi, head of Pharmakom in Newark, has a desktop screen too. This is a general purpose computer which at various times displays video of his daughter and a corporate database entry about Anna, the Pharmakom founder.

jm-15-takahashi-a-adjusted

There is no keyboard, but later we will see that the desk surface has hand gesture tracking capability. Here the screen displays an onscreen video phone window and numeric keypad, similar to what we saw in the New Darwin sequence, but Takahashi doesn’t use that interface. Instead he just says “Get me Karl” and the phone dials the recipient automatically.

Takahashi doesn’t prefix his command with a control phrase such as“Siri” or “Computer” which would imply that the computer is always listening. For an executive with a private office this would be reasonable: who else could he be addressing? A second possibility is that the computer does voice recognition and would not respond to commands from anyone else.

Street Preacher’s Phone

As before, the recipient has chosen to show a video splash screen on connection instead of a live video feed.

jm-15-takahashi-b-adjusted

“Karl” is more commonly known as Street Preacher and works within a church of sorts. We don’t know whether this is genuine religion belief on his part or a cover operation. His phone system is built into a large book, which I thought was intended to be a Bible but Chris identifies as a 16th century ecclesiastical history. There are no controls visible, but we see Karl “pick up” by opening the book so perhaps he “hangs up” by closing it again. Otherwise it could be operated purely by voice.

jm-15-takahashi-c-adjusted

Public phone

Earlier in the film, Johnny picked up an “Infobahn 3000” handset with built in phone keypad.

jm-16-phonebooth-a

His next phone call is from a public phone booth. On screen we see the now familiar videophone keypad. (Apparently this time in cyan, although it’s a very minor color shift.). To the right of the screen are physical buttons, some of which are labelled “start” “stop” and “pause” so perhaps duplicate the onscreen controls. Johnny begins by borrowing Jane’s phone card and swiping it through the payment slot.

jm-16-phonebooth-b-adjusted

The red Infobahn handset is connected to Jane’s card by a cable, although we don’t see Johnny doing this. Johnny types on the handset keypad rather than using the onscreen controls, presumably doing some hacking through the interface.

At first sight it seems unlikely that the phone system could be hacked through an EFTPOS card reader. However there is a long and unhappy history of programmers leaving backdoors and unused functionality in products, often excused with “Well, nobody else knows about it”, which are then exploited. Payment cards themselves often have embedded integrated circuits. This particular hack is not completely implausible.

jm-16-phonebooth-c

When the Pharmakom splash screen appears, Johnny types again on the handset. He is manipulating the internal company phone system to gain access to a number that normally would not be available to the public.

jm-16-phonebooth-e-adjusted

The new number connects Johnny to a surprised corporate type who wants to know how Johnny got through.

jm-16-phonebooth-g-adjusted

We’ll learn later on that this gentleman is not at all who he seems to be. For now, note that Johnny talks and listens directly to the screen and speakers in the phone booth, not the handset he is holding.

Spider phone

Just before his brain is scanned by Spider, Johnny tries to make another call. This time he uses a typical 1990s computer CRT display and keyboard. He wears a conventional looking earpiece and microphone, and there is a small camera mounted on top of the display. He types the number on the keyboard and reaches a Pharmakom receptionist, but Johnny is interrupted.

jm-19-old-phonecall-adjusted

Van call

The last phone call is made by Johnny to Pharmakom again. This time he is in Spider’s van, which doesn’t have a built in phone like the taxi we saw earlier. He uses the handset for audio and a small portable screen for video. There must be a wireless transmitter and receiver somewhere, but it isn’t obvious.

jm-22-puppet-call-a-adjusted
jm-22-puppet-call-b-adjusted

Johnny doesn’t realise that he is actually talking to Takahashi, the head of Pharmakom, through a puppet avatar, which I’ll talk about in the next post. 

The Memory Doubler

In Beijing, Johnny steps into a hotel lift and pulls a small package out his pocket. He unwraps it to reveal the “Pemex MemDoubler”.

jm-4-memdoubler-a

Johnny extends the cable from the device and plugs it into the implant in his head. The socket glows red once the connection is made.

jm-4-memdoubler-b-adjusted
jm-4-memdoubler-c-adjusted

Analysis: The jack

The jack looks like an audio plug, and like most audio plugs is round and has no coronal-orientation requirement. It also has a bulbous rather than pointed tip. Both of these are good design, as Johnny can’t see the socket directly and while accidentally poking yourself with a headphone style point is unlikely to be harmful, it would certainly be irritating.

The socket’s glow would be a useful indicator that the thing is working, but Johnny can’t see it! Probably these sockets and jacks are produced and used for other devices as well, as red status lights are common in this world.

There are easier and more convenient fictional brain plug interfaces, such as the neck plugs previously discussed on this website for Ghost In The Shell. But Johnny doesn’t want his implant to be too obvious, so this not so convenient plug may be a deliberate choice. Perhaps he tells inquisitive people that it’s for his Walkman.

Analysis: The device

The product name got a few chuckles from audiences in the 1990s, as the name is similar to a common classic Macintosh extension at the time, the Connectix RAM Doubler. This applied in-memory lossless data compression techniques to allow more or larger programs to run within the existing RAM.

The MemDoubler is apparently a software or firmware updater, modifying Johnny’s implant to use brain tissue twice as efficiently as before. It has voice output, again a slightly artificial sounding but not unpleasant voice. This announces that Johnny’s current capacity is 80 gigabytes. As the update is applied, a glowing progress bar gradually fills until the voice announces the new capacity of 160G.

jm-4-memdoubler-d

(Going from 80G to 160G seems quaint today. But we should remember that the value of a mnemonic courier is secrecy, not quantity.)

Why does the MemDoubler need voice output? For such a simple task, the progress bar and a three digit numeric counter would seem adequate. But if there are complications—which for something wired into the brain might have an all too literal meaning for “fatal error”—a voice announcement would be able to include much more detail about the problem, or even alert bystanders if Johnny is rendered unconscious by the problem. (Given how current software installers operate, Johnny is fortunate that the MemDoubler did not insist on reciting the entire end user license agreement and warranty before the update could start.) Maybe the visual should be the default (to respect his professional need for secrecy), and the voice announcement adopted in an alert mode.

It’s also interesting that Johnny installs this immediately before he needs it, in the lift that is taking him to the hotel room where he will receive the data to be stored. Suppose someone else had been in the lift with him? In this world of routine body implants doubling your memory is probably not a crime, but at the time of writing diabetics will inject themselves in private even though that is harmless and necessary. Perhaps body-connected technology will be common enough in 2021 that public operation is considered normal, just as we have become accustomed to mobile phone conversations being carried out in public.

Videoconferencing

BttF_122

Marty Sr. answers a call from a shady business colleague shortly after coming home. He takes the call in the den on the large video screen there. As he approaches the screen, he sees a crop of a Renoir painting, “Dance at La Moulin de la Galette,” with a blinking legend “INCOMING CALL” along the bottom. When he answers it, the Renoir shrinks to a corner of the screen, revealing the live video feed with his correspondent. During the conversation, the Renoir disappears, and text appears near the bottom of the screen providing reminders about the speaker. This appears automatically, with no prompting from Marty Sr.

This is an augmented reality teleconference, as mentioned in Chapter 8 of Make It So: Interaction Design Lessons from Science Fiction. See more information in that chapter. In short, it’s a particularly good example of one type of augmentation that is very useful for people having to interact with networks of people much larger than Dunbar’s number equips us for. Unfortunately, the information appears in a distracting scroll across the bottom, and is not particularly pertinent to the conversation, so could benefit from a bit of context awareness or static high-resolution display to be really useful.

When the conversation is done, the screen fades to black, and an animated AT&T logo appears as a female voice offers Thank you for using AT&T. Afterwards, another odd crop of a famous impressionist artwork appears on screen. (1887-88 Self-Portrait with Grey Felt Hatby Van Gogh, if you’re curious.) This must be a preference set by the McFlys.

During the conversation, Needles convinces Marty Sr. to front some money for a shady deal. To provide the money, he grabs his briefcase and presses one of several lit buttons on its surface. A thin reader raises from the surface on mechanized accordion arms. The slot glows white, and Marty inserts his ID card into the recess and yanks it to the right. Marty presses another button and the reader retracts.

Though pretty cool, this portable authenticator seems multimodal, the two objects are both of the same type, i.e. something he possesses, and so is only marginally more secure than unimodal systems.

Almost instantly, Marty is caught in the act and fired by his boss over the same video phone. To bring home the news, Fujitsu-san presses some button off screen and large letters YOU’RE FIRED appear overlaid on the screen, animating repeatedly for emphasis. Simultaneously, he sends Marty faxes, which Marty receives numerous times in the faxes in his suitcases and others which are installed all over the house, including the in the closet where Jennifer is hiding.

I’m not sure what would lead Needles or Marty(2015) to engage in something illegal that is obviously and instantly discoverable by authorities, but that is not a matter of interaction design.

Barbarella’s energy box

Barbarella-037

In addition to the portable brainwave detector, Dianthus also provides Barbarella with a number of weapons from the Museum of Conflict for her mission. All of these weapons are powered by a single energy box.

We only see it in use after she fires a single shot from the smallest of the weapons. She tries a second shot, but when it doesn’’t work, she glances at a device on the cuff of her boot. The device is designed in a taijitu, a yin-yang set of lights: one red, one white. They are blinking in an alternating pattern, and after viewing it she tells Pygar, ““My energy box is completely dead.””

Energy-Box

Though having a visual signal is quite useful to understand the state of an invisible resource like power, the signal would be much more useful if it showed the amount of energy remaining, and gave warnings before the power was completely out. Failing all that, it would be more useful if she just put the device on the glove of her shooting hand so it was in her field of view at all times.

And though Barbarella’s culture doesn’t understand war, even a peaceful person can quickly come to realize the risk in making your available resources—like power for your weapons—wholly visible to your enemies.

Portable brainwave detector

Barbarella-032

Through the atom transmitter Dianthus bestows several gifts on Barbarella to help her with her mission. The first of these is the “portable brainwave detector…to test for Durand-Durand’s presence.” To operate it, Barbarella must press “a contact,” (Dianthus is offscreen when he indicates the contact, but later we see her operating the leaf-like button near the wrist) and if Durand-Durand is around, the ball of lights will glow and an alarm will sound.

vlcsnap-00002

The device is wearable, wrapping around Barbarella’s forearm, and held in place by a ring. This aspect of the design is good, since it means the device is ever-present for operation, and the design of it makes it lovely enough to be overlooked as a fashion accessory. In fact many characters see her wearing it and make no mention.

PBD_worn

Manual activation is less than ideal, though, since this might tip off the suspect. This is especially true with the blinking, glowing ball of light and audio feedback. And, in fact, this is what happens later in the film when Durand-Durand trips over the device. The blinking light and audio catch his attention, betray the device for what it is, and blow Barbarella’’s cover in the process.

Portable Brainwave Device

The best feedback would be invisible, like a haptic vibration through the cuff to her skin. Ideally, the device would be constantly on, to detect the subject passively, the moment he came into range. But presuming battery life is the issue, the activation cue should be something much more subtle, like Barbarella’s touching the back of the ring with the thumb of the same hand. Such a gesture would match the existing design of the object, be discreet to an observer, and yet still discrete enough to prevent accidental activation.
