Report Card: Logan’s Run
For our purposes, Dome City is a service. Provided by the city’s ancestors to provide a “good life” for their cloned descendants in a sustainable way, i.e., a way that does not risk the problems of overpopulation. The “good life” in this case is a particular hedonistic vision full of fashion, time at the spa, and easy casual sex.
There’s an ethical, philosophical, and anthropological question on whether this is the “right” sort of life one would want to structure a service around. I suspect it’s a good conversation that will last at least a few beers. Fascinating as that question may be, looking into the interaction design requires us to accept those as a given and see how well the touchpoints help these personas address their goal in this framework.

The answer does not program
Logan’s life is changed when he surrenders an ankh found on a particular runner. Instead being asked to identify, the central computer merely stays quiet a long while as it scans the objects. Then its lights shut off, and Logan has a discussion with the computer he has never had before.
The computer asks him to “approach and identify.” The computer gives him, by name, explicit instructions to sit facing the screen. Lights below the seat illuminate. He identifies in this chair by positioning his lifeclock in a recess in the chair’s arm, and a light above him illuminates. Then a conversation ensues between Logan and the computer.
The computer communicates through a combination of voice and screen, on which it shows blue text and occasional illustrative shapes. The computer’s voice is emotionless and soothing. For the most part it speaks in complete sentences. In contrast, Logan’s responses are stilted and constrained, saying “negative” instead of “no,” and prefacing all questions with the word, “Question,” as in, “Question: What is it?”
On the one hand it’s linguistically sophisticated
Speech recognition and generation would not have a commercially released product for four years after the release of Logan’s Run, but there is an odd inconsistency here even for those unfamiliar with the actual constraints of the technology. The computer is sophisticated enough to generate speech with demonstrative pronouns, referring to the picture of the ankh as “this object” and the label as “that is the name of the object.” It can even communicate with pragmatic meaning. When Logan says,
“Question: Nobody reached renewal,”
…and receives nothing but silence, the computer doesn’t object to the fact that his question is not a question. It infers the most reasonable interpretation, as we see when Logan is cut off during his following objection by the computer’s saying,…
“The question has been answered.”
Despite these linguistic sophistications, it cannot parse anything but the most awkwardly structured inputs? Sadly, this is just an introduction to the silliness that is this interface.
Logan undergoes procedure “033-03,” in which his lifeclock is artificially set to blinking. He is then instructed to become a runner himself and discover where “sanctuary” is. After his adventure in the outside performing the assignment he was forced to accept, he is brought in as a prisoner. The computer traps him in a ring of bars demanding to know the location of sanctuary. Logan reports (correctly) that Santuary doesn’t exist.
On the other hand, it explodes
This freaks the computer out. Seriously. Now, the crazy thing is that the computer actually understands Logan’s answer, because it comments on it. It says, “Unacceptable. The answer does not program [sic].” That means that it’s not a data-type error, as if it got the wrong kind of input. No, the thing heard what Logan was saying. It’s just unsatisfied, and the programmer decided that the best response to dissatisfaction was to engage the heretofore unused red and green pixels in the display, randomly delete letters from the text—and explode.That’s right. He decided that in addition to the Dissatisfaction() subroutine calling the FreakOut(Seriously) subroutine, the FreakOut(Seriously) subroutine in its turn calls Explode(Yourself), Release(The Prisoner), and the WhileYoureAtItRuinAllStructuralIntegrityoftheSurroundingArcitecture() subroutines.
Frankly, if this is the kind of coding that this entire society was built upon, this whole social collapse thing was less deep commentary and really just a matter of computer Darwinism catching up with them.
The Evidence Tray (ordinary use)
Sandmen surrender any physical objects recovered from the bodies of runners to the Übercomputer for evaluation via a strange device I’m calling The Evidence Tray.
As a Sandman enters the large interrogation chamber, a transparent cylinder lowers from the ceiling. At the top of this cylinder an arm continuously rotates bearing four pin lights. A chrome cone sits in the center of the base. The Sandman can access the interior of the cylinder through a large oblong opening in the side the top of which is just taller than Sandmen (who seem to be a near-uniform height).
The Sandman puts any evidence he has found into the bottom of this cylinder. (What if the evidence was too large to fit? What if the critical evidence is not physical, or ephemeral? But I digress.) In response to his placing the objects, lights on the rotating arm illuminate, scanning them. The voice of the Übercomputer prompts the Sandman to “identify,” a request that is repeated on a large screen mounted on the wall in view through the transparent backing of the Evidence Tray.
The Sandman identifies himself by placing his palm on a cone in the cylinder’s center, positioning his lifeclock in the small indention in its tip. The base section of the cylinder illuminates, and after a pause, the voice and screen confirm that his identity has been “affirmed.” Logan removes his hand, and in a flash of blue light the objects in the tray disappear. The film gives no clue as to whether the objects are teleported somewhere or disintegrated into thin air.
Objections
There are of course the usual objections to the authentication. The lifeclock check is really a biometric check, something that Logan “is” (since he can’t remove the lifeclock) and—per the principles of multifactor authentication—should need to provide an additional factor, such as something he has (like a key) and something he knows (like a password).
There’s another objection there to the fact that the authentication requires that his hand be put into a teleport/distingration chamber. Perhaps narratively this shows the audence the insane levels of trust citizens have in their Nanny Program, but for the real world let’s just say it’s best that you don’t require police to submit to a Flash Gordon Wood Beast just to hand over exhibit A.
There’s a nice touch to the transparent walls allowing him to see the computer screen through it, to get the visual confirmation of what he’s hearing. But I suspect the curved surface also adds a bit of distortion to his view that doesn’t help readability. So the industrial design aspects of the interface sort of even out. Unless I’m missing something. Any industrial designers want to weigh in?
A final objection is the unnecessarily vast architecture that is part of the workflow. Why this giant room with a thin cylinder in the middle of it? Sure there are narrative reasons for it (welcome to this digital heart of darkness) but it seems like something that Sandmen would be doing routinely, and this giant ritual just makes a creepy, big deal about it.
Better
Better might be a wide, waist-high cubby off to the side of their offices, whatever those are, with a wide tray and computer screen. Sandmen could drop the evidence into the tray and place their hands into an authenticator outside the tray, initiating the scan. This would save them the awkward time of waiting for the computer to order them to authenticate, and tightly couple the objects with their identity. The improved semiotics say, “I, Logan, found these and am surrendering them to you.” Then if the computer needed to speak more about it, it could summon them to an interlocution room, or something with a similarly awkward 70s name.
Dispatch
At dispatch for the central computer, Sandmen monitor a large screen that displays a wireframe plan of the city, including architectural detail and even plants, all color coded using saturated reds, greens, and blues. When a Sandman has accepted the case of a runner, he appears as a yellow dot on the screen. The runner appears as a red dot. Weapons fire can even be seen as a bright flash of blue. The red dots of terminated runners fades from view.
Using the small screens and unlabeled arrays of red and yellow lit buttons situated on an angled panel in front of them, the seated Sandman can send a call out to catch runners, listen to any spoken communications, and respond with text and images.
*UXsigh* What are we going to do with this thing? With an artificial intelligence literally steps behind them, why rely on a slow bunch of humans at all for answering questions and transmitting data? It might be better to just let the Sandmen do what they’re good at, and let the AI handle what it’s good at.
But OK, if it’s really that limited of an Übercomputer and can only focus on whatever is occupying it at the moment, at least make the controls usable by people. Let’s do the hard work of reducing the total number of controls, so they can be clustered all within easy reach rather than spread out so you have to move around just to operate them all. Or use your feet or whatever. Differentiate the controls so they are easy to tell apart by sight and touch rather than this undifferentiated mess. Let’s take out a paint pen and actually label the buttons. Do…do something.
This display could use some rethinking as well. It’s nice that it’s overhead, so that dispatch can be thinking about field strategy rather than ground tactics. But if that’s the case, it could use some design help and some strategic information. How about downplaying the saturation on the things that don’t matter that much, like walls and plants? Then the Sandmen can focus more on the interplay of the Runner and his assailants. Next you could augment the display with information about the runner, and perhaps a best-guess prediction of where they’re likely to run, maybe the health of individuals, or the amount of ammunitition they have.
Which makes me realize that more than anything, this screen could use the hand of a real-time strategy game user interface designer, because that’s what they’re doing. The Sandmen are playing a deadly, deadly video game right here in this room, and they’re using a crappy interface to try and win it.
Cleanup
Sandmen have a clean-up crew to quickly rid the citys floors of the unsightly corpses they create when they terminate runners. Logan summons one through the CB function of his SandPhone, telling dispatch, “Runner terminated, 0.31, ready for cleanup.”
Minutes later, Cleanup arrives. This crew floats around the city in a slow-moving hover platforms, that look a little like a vertical knee raise machine with anti-gravity pads and a faulty muffler. The controls aren’t apparent, but the operator maneuvers the platform over the cadaver to spray it with a fast-acting solvent that emits out the base.
This is the surface question of the Cleanup platform interface. If the operators don’t move, how are they controlling the platform? Of course it could be a brain interface, but that’s an easy answer. There are at least three alternative types of input that could explain what we see on screen.
- Force-sensing resistors or strain gauge that read the amount of force being applied to a stationary surface and act accordingly. The grips could be outfitted with force strips for each finger giving a high degree of complex input.
- Gaze interactions, where eye tracking equipment registers glances, blinks, pupil dilation, and eyelid spread over time as controls.
- Subvocal recognition allow a user to move their throat and mouth as if they were speaking, and even without actually producing any sound, register it as speech input.
Each of these technologies permit input via movements that are difficult to detect through observation, but facilitate rich enough input to pilot a personal vehicle through 3D space. Sadly, this level of sensory sophistication is not in evidence anywhere else in the film, so we’ll just have to chalk it up to a nifty tech for our real world toolboxes.
And though these technologies are cool, they don’t answer any of the experience or service design questions from the perspective of the Übercomputer. Why it is good for the operator to appear perfectly still in the first place? Is there some reason why they need to be dehumanized or robotic? It can’t be that they’re doing something horrible. Sandmen do the actual killing (and as we see do it gleefully, cruelly) and are highly visible, clearly human participants in the system?
The SandPhone
Not everyone is comfortable giving over to the flimsy promise of Carrousel [sic]. Some citizens run, and Sandmen find and terminate these cultural heretics.
Sandmen carry a device with them that has many different uses. It goes unnamed in the movie, so let’s just call it the SandPhone. It is a thick black rectangle about 20cm at its long edge, about the size of a very large cell phone. Near the earpiece on one broad side is a small screen for displaying text and images. Below that is a white line. The lower half of this face is metallic grill that covers a microphone. On the left edge is a momentary button that allows talking. Just above this is a small red button. When not in use, the device is holstered on the sandman’s belt.
The SandPhone lets the Sandman receive information through a display that can show both image and text. The Sandman sends back information and requests by voice in a CB radio metaphor.
Notifications
The first time we see the device is when Logan and Francis are attending Carrousel. Somehow, on his belt it catches his attention. With the crowd too loud for sound, and no evidence it’s light, my bet’s on haptics. Realizing he’s got a message, he picks it up, presses the edge button and the screen displays two lines of text:
RUNNER: GREAT HALL
ENTRANCE WEST.
He then puts the device to his face as we would a cell phone and shouts, "Affirmative!" as loud as he can.
Perp wayfinding
Running with the device outside the Great Hall, Logan uses the SandPhone as a detector. By holding it flat out in front of him he hears a rhythmic pulse. Turning it this way and that, he listens for the change in pitch. It rises when he is pointing towards the targeted runner.
Bio identification
When he and Francis have terminated the runner, he snaps the device off his belt, and pressing the edge button, he reports back to dispatch, "Runner terminated, 0.31. Ready for cleanup." Then by placing the device near the head of the dead runner, the device displays on the screen the last photographic image of him on file. Since the face on the SandPhone screen does not match the face he sees before him, Logan lifts the device to his face and, holding the edge button, requests an identity check of dispatch. Instantly he pulls the device away from his face to show the text:
IDENT. AFFIRM
NEW YOU #483
FACE CHANGE.
Send backup
Much later in the film we see Logan alert dispatch to the location of the underground hideout by reaching down to the holstered device and pressing the white line button on its face. Its screen pulses green, and his position is highlight on the runner board (see below) at dispatch. Minutes later the location is raided by Sandmen.
Analysis
The first thing to note is that this is pretty close to a modern smart phone. He receives images and text messages, can talk to dispatch, and it has a biometric capability for identifying citizens. It’s tempting to paint this as visionary, but keep in mind that the first mobile phone was demonstrated in 1973, three years earlier, so it’s likely that the film makers were riffing off of the demo technology they’d heard about or maybe even seen in person.
We evaluate an interface’s design by how well it helps its user achieves his goals. (Even if those goals are anethma. That’s how we judge an interface.) In this case, the SandPhone helps Logan get the information he needs, when he needs it, across multiple channels. It doesn’t distract him with other functions. It’s context aware and doesn’t apparently have battery issues.
There are improvements of course.
We should make sure his hands are free by making the information available as an augmented reality display instead of a handheld device. This would also give him the information privately rather than display it for anyone (notably members of the resistance) to see it. Wayfinding would be more sensible as an overlay to his vision through this device.
Some surface tweaks might also be made, such as giving him a means of text input so he wouldn’t have to shout above the roar of Carrousel. Some silent means of input would help for when he needs to provide silent input as well. First I thought optical inputs might be ideal, given the augmented reality, but we don’t want his eyes distracted like that, even for the duration of glances. Instead some other gestural input—perhaps a face twitch or subvocal input—that lets him keep the rest of his body tense and ready for action.
Citizen biometrics should be a background fact, given the penopticon of Dome City. The information would come to him when he gets his assignement. But turn those same biometrics around on Logan, and his body could request reinforcements before he even thought to do so manually. When his heart rate elevates and galvanic skin response lowers, dispatch would know something was up, and route backup immediately.
A strategic interaction designer would even ask why he has to chase runners at all, when predictive algorithms could guess which citizens were likely to run and take action to forestall their rebellion. But then we’re into Minority Report, and this needs to stay Logan’s Run.
Carrousel [sic]
The hedonistic and carefree lifestyle in Dome City comes with a price. When a citizen’s lifeclock begins to blink, it means he or she is now too old, and due to attend a public ritual called Carrousel and die in a public spectacle. As this is a major event in the lives of citizens, most of the public attends these events.
Description
Lastdays are outfitted in special clothes and masks. After filing wearing these costumes and encircling a huge lifeclock, lastdays expose their palms to show the blinking lifeclock to confirm their status.
Then they look up to a crystal at the ceiling that begins to spin. The lastdays become weightless, and they struggle to reach the top, for the opportunity to reach renewal.
When they fail—and they always fail—they explode in a fiery shower of sparks. The audience greets each explosion with a roar of excitement and applause.
Analaysis
A public ritual is at the edge of the definition of interface that I provided in Make It So:
All parts of a thing that enable its use.
But in this case, the culture of Dome City pays for its lavish lifestyle admidst fixed resources with these public executions, and something must turn what by rights should be met with horror and revulsion into something palatable, even enjoyable. It is in this sense that citizens use Carrousel.
Nearly everything we see in the ritual helps to hide its raw, morbid truth. The false promise of renewal hides the finality of the act. The masks won by participants hide the individual identity from the audience, easing the sense of personal loss. The identical costumes dehumanize participants, underscoring their role in the culture. The ritual actions give participants something to do during a time that is psychologically stressful. The public-ness of it reinforces its cultural importance and imprints onto the audience that one day, they do will participate.

Dome City Rail
Citizens move between the distant parts of the city by means of a free, public transportation system. It is an ultra-light rail, featuring cars for two passengers, that move between long translucent tubes that connect the domes of the city. When one car stops at a station, its door slides open to allow exit and entry. We never see a car waiting behind another. Once seated, riders press a red button on a panel between the two seats (just visible in the screen capture below), and the car seals shut and takes off to the next station.
A small panel inside the car alerts passengers to the name of the next stop as well as any additional information that is of use. When Logan and Jessica head to Cathedral Station, the panel blinks a red light to draw their attention. (The paired green light is never seen illuminated. What’s it there for?) A female voice says "Entering a reservation for violent delinquents. Authorized persons only." The screen before them reads, “personal risk area." (For those wondering why it stops there at all, anyone can get out of their car here, but Logan has to use his personal communication device with Control to have the gate to Cathedral opened.
The panel and voice output are useful to alert riders whose attention has drifted. Text could be put in the environment of course, since this information rarely changes, but it’s a bit harder to read when it’s moving and isn’t as likely to gain a distracted rider’s attention.
The last bit of interface is the LED displays on the walls of fancier stops like Arcade (the dome with the shopping mall and Caroussel.) We never see this sign change, but it makes sense that while riders are at the station, it displays the stop as a reinforcing bit of information, and can display alternate messages for citizens waiting on a car otherwise.
The interface is incredibly simple because the system is so constrained. You have to hop on at a station, and like an airport tram or a shabbat elevator, the car runs along a fixed loop. You hop out when you’re there. The main negative issues I see are selecting a stop and perhaps safety.
Selecting a stop
It’s a waste of time and energy to have cars stopping and starting at unwanted stations. It can also be distracting to have the car tell you about all the intermediate stops when you’re not interested in them.
To solve this problem, the track system should be built with track bypasses so we have to worry less about track congestion at stops. Then riders could either ride the “local” from stop to stop, or optionally have some way to indicate their desired stop, bypassing the ones in between. What’s this indication look like? In the panopticon of Dome City, the Übercomputer can just listen to your conversations wherever you’re having them, and when you get to a car default to the stop expressed in conversation. Logan and Jessica had just spoken about Cathedral Station, so when they stepped in, it could have just asked them to confirm. If the selection was wrong, or no stop had been mentioned recently, riders should be able to speak their destination or the event to which they’re headed. As a last fallback, a screen displaying discrete options could allow them to select a destination by touch or gesture.
Rider safety
The safety issue is subtle, but if riders have no control over the cars, why are the seats facing forward? It’s much safer in a head-on collision to be seated "backward," like an infant’s car seat. Psychologically, people are most comfortable sitting forward to see in the direction of potential collisions, but if you lived in an UberNanny State like Dome City, the system would just force people to sit in the safest way.
It’s going to be more complicated than this
Getting public transportation experience design right is tough enough. But it’s going to get more complicated. Here at the dawn of computer-driven cars and computer-requested and computer-wayfinding "routeless" busses, the challenges will be manifold. How do you signal a stop? How does it gracefully degrade? How do you pay? How do you get to a just-in-time defined stop? How do you indicate your destination(s), willingness to share the ride, and urgency? How do you not disenfranchise people just because they have no cell phone? Dome City is small and constrained enough to ignore such problems, like a light rail in a small, wealthy, downtown core, making it almost too simple to be instructive.
