Abstract
A system for controlling the automatic scrolling of information on a computer display. The system includes a computer display, a computer gimbaled sensor for tracking the position 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. A scrolling function is performed based upon the screen gaze coordinates of the user's eye relative t activation area(s) on the display. The gimbaled sensor system contains a platform mounted at the top of the display. The gimbaled sensor system tracks the user's head and eye allowing the user to be free from attachments while the gimbaled sensor system is tracking, still allowing the user to freely move his head. A method of controlling automatic scrolling of information on a display includes the steps of finding a screen gaze coordinate on the display of the user determining whether the screen gaze coordinate is within at least one activated control region, and activating scrolling to provide a desired display of information when the gaze direction is within at least one activated control region. In one embodiment, the control regions are defi…
