Haggerty and Ericson describe a related operation within surveillance systems, in which bodies are "broken down into a series of discrete signifying flows” that can subsequently be reassembled as informational “data doubles.” Breathing Room does not produce a data double in this fuller sense. It deliberately constructs something much poorer. The system does not reconstruct an identity or profile. It retains only a narrow operational fragment of an encounter: someone crossed this boundary.

This distinction is important. Translation is not simply representation. The count does not represent the person in their totality, nor does it need to. It produces a version of bodily presence that can participate in another operation.

Something becomes unavailable through this translation: intention, familiarity, discomfort, vulnerability, expectation and the many other qualities through which entering a shared space may be experienced.

But not my membrane. I enter and it changes. You enter and it changes again. Everyone inside contributes to the position of the same boundary. And by presence, I do not simply mean that my body happens to be somewhere. I mean that I have become perceptible enough to make a difference. Before the room can move around me, it has to know that I am there. The room itself exists as a complete system, with or without human in it. I enter the room would preferably disrupt the system. Like in Charlie Angels, Cameron Diaz broke into Red Star mainframe by flipping and tumbling past a room full of laser beams. I fumble onto the laser beams, would make my presence very perceptible.

One disrupted laser beam could not tell if I’m still present in side or not, but with 2 laser beams, that would be sufficient to tell. First beam breaks, then the second one: +1. That is me now. Or rather, that is the part of me the system can use.
