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.
