Computer system has data processor that generates feedback data based on absolute position of user's gaze point with respect to display during initial phase, and based on image data during phase subsequent to initial phase

摘要

Image devices (135a,135b) register image data representing the movements (MR) of the body (145) of a user (140) and forward a representation of the image data to a data processor (110). The data processor generates feedback data based on the absolute position of the user's gaze point with respect to a display (120) during an initial phase. The data processor generates feedback data based on the image data during a phase subsequent to the initial phase. Independent claims are also included for the following: (1) a method for controlling a computer system; (2) a computer program; and (3) a computer readable medium.
