Patent attributes
A user-worn eye-tracking device, method, and system. The eye-tracking device may have an outward appearance resembling standard eyeglasses or sunglasses, and may also comprise a built-in wireless transceiver and an optional optical display. In addition to eye-tracking, the device can allow the user to inconspicuously transmit data by a process in which the user simply moves his or her eyes and/or optionally gazes at various internal or external display targets. The device's eye tracking system and software track the motion and gaze of the user's eyes, and convert this gaze into eye-position data and/or message symbols and system control commands. The device then transmits any of the resulting eye position data, commands or messages using its transceiver. In a preferred embodiment, the device is self-contained and operates, when placed on the user's head, without the need of external battery packs or external transceivers.
