Patent US 6,421,064

A system for controlling the automatic scrolling of information includes a screen, a computer system, gimbaled sensor system for following and tracking the position and movement of the user's head and user's eye, and a scroll activating interface algorithm using a neural network to find screen gaze coordinates implemented by the computer system so that scrolling function is performance based upon the screen gaze coordinates of the user's eye relative to a certain activation area on the screen. A method of controlling scrolling includes the acts of finding a screen gaze coordinates on the screen, determining whether the screen gaze coordinate is within at least one activated control region, and activating scrolling to provide a display of information when the gaze direction is within at least one activated control region.
