EYE-TRACKING SYSTEM FOR ENTERING COMMANDS

Abstract:

In certain embodiments, an eye-tracking system for entering commands includes a computer, a pair of three-dimensional glasses, and a display. The computer generates a three-dimensional graphical user interface with graphical elements, where each graphical element corresponds to a command. The pair of three-dimensional glasses directs the three-dimensional graphical user interface towards a pair of eyes of a user. The display displays the graphical elements to the user. The display includes light-emitting diodes configured to illuminate the pair of eyes and a camera configured to track movement of the pair of eyes relative to the three-dimensional graphical user interface to yield a pair of tracked eyes. The computer interprets a movement of the pair of tracked eyes relative to the three-dimensional graphical user interface as an interaction with a selected graphical element, and initiates the command corresponding to the selected graphical element.
