This document suggests a line of investigation into the problem of ARV displacement, using a composite quantum system model.
Section 2 includes a literature review relevant to this work.
Section 3 introduces the composite quantum system model associated to a viewer and the feedback images shown at feedback time. A simplified two state quantum system approximation is used.
Displacement is assumed to occur because confidence rankings associated with ARV trials may not correspond to the underlying probabilities of the event, but rather to their projection on a 2D plane following a perspective transform and may be distorted by a fisheye lens effect. The solution is to compensate for this effect by spacing ARV trials. The parameters of the perspective transform are unknown (orientation, field of view, focal distance, etc.).
