PS-COO-144 · r2 COORDINATION OBSERVED ENGAGED

PARTIAL VIEW RECONCILIATION

One object between two people, showing each of them a different face.

01 DEFINITION

Condition in which a single device stands between two people and presents a different face to each, so what each is being shown is unavailable to the other, and neither can tell whether the exchange is going as they think it is.

02 CONDITIONS

UNCERTAINTY CONFLICTING Each side holds a different account of what is currently on the object.

TIME PRESSURE MODERATE The exchange keeps moving; neither side can stop to compare faces.

ERROR ASYMMETRY ASYMMETRIC Reading something unfinished and waiting through a silence are not the same failure.

OPERATOR STATE CONCURRENT Both people are conducting the exchange while reading their own side of it.

03 WHERE IT APPEARS

MEDICALA screen between clinician and patient shows each of them a different side of the same consultation.

RETAILA terminal facing both ways puts one account in front of the customer and another in front of the assistant.

PUBLIC SERVICEA counter device shows the applicant one thing and the officer another, and neither sees the other's side.

FINANCEA shared surface at a desk presents different fields to the two people sitting either side of it.

EDUCATIONA device between tutor and learner shows each a view the other cannot see.

LOGISTICSA handheld held between driver and receiver displays a different face to each at the point of handover.

04 WHAT AEON WORKED THROUGH HERE

A device standing between two people carried the exchange in both directions, and each of them saw only their own side of it. One was reading something the other had not finished writing; the other was waiting through a silence that meant typing and could have meant anything. The work went into what each face says about the other — that something is coming, that it has been read — so that neither of them was running the conversation blind.

What stays unresolved is what each side is owed about the other's face — showing both to both turns the object into a document they read together rather than a channel between them, and showing neither leaves each of them running a conversation they can only half see.
