Patent ID: 8531355

Claim:
A self-contained, head-mountable, vision-controlled device for wirelessly transmitting and receiving text information in an inconspicuous manner using only eye-gaze direction control, comprising: a head-mountable frame configured to hold a lens in front of an eye of a user; at least one user eye-tracking sensor positioned to optically track gaze direction of one or both eyes of the user; at least one processor programmed to execute eye tracking executable code and control executable code to rotate a virtual surface interface using only eye gaze direction mediated commands; at least one optical system configured to render a virtual image of a visual display viewable by a user of said device, said optical system spatially positioned within a boundary defined by said lens in front of the eye of the user; wherein said visual display displays at least one target for a symbol intended for wireless transmission when said eye of the user is directed toward said target, said target being positioned on a rotating virtual surface spinning perpendicular to the user's eye gaze direction; at least one wireless transceiver mounted on said frame, said wireless transceiver receiving wireless information and transmitting said wireless information to said optical system; at least one battery mounted on said frame to power said at least one eye tracking sensor, said at least one processor, said at least one wireless transceiver, and said at least one visual display; and wherein said at least one processor programmed to execute said executable eye tracking code, and said executable control code causing said eye-tracking and display device to transmit wireless information by tracking the gaze direction of said eye of said user with said eye tracking sensor, and using only the gaze direction of said eye of said user as input translating the gaze direction of said eye of said user into rotating or moving said virtual surface to display at least one symbol or command, selecting said at least one symbol or command, constructing text to be transmitted, and transmitting said text using said at least one wireless transceiver.
