This post from the médialab at Sciences Po project AIME describes what I1 have been talking about as the click, in PCP. Christophe Leclercq writes:
What we are trying to capture is both much more delicate and at the same time omnipresent and often invisible. In experience, we are only interested in those moments where one can clearly discern that one has the wrong template, that one is in the middle of deeply shocking one’s interlocutor, or that the beings one is addressing seem to be disconcerted, off-balance, vague, embarrassed, or ill-at-ease. This, then, is a situation of ontological crisis, what one could call, via the etymology, deontological crises. When one is in the midst of such crises that one has to begin a kind of delicate negotiation to choose among the available templates the one that best captures the situation. And, if you don’t have one to hand, well then, you have to get busy inventing it.
