He definitely says it. I think the prototype is maybe simulating gaze detection at the moment based on the position of the reticle position set by the thumbstick and possibly current head position + previous position + guess work on what a players focus is likely to be. I certainly get the impression from the way he says it that this is something they are looking at the moment in a more advanced way and is a common conversation point in their software/hardware dev teams at the moment. VERY exciting.
