Computer interface system and method
First Claim
1. A system capable of remotely interfacing with a computer using visual cues, said system comprising:
- a video camera capable of capturing an image and converting the captured image into a video data stream; and
a video processor in communication with the video camera, wherein the video processor is capable of recognizing at least one visual cue, and in response to recognizing a visual cue, generating a computer command set and presenting the computer command set to the computer for execution.

Abstract
A system for interfacing with a computer using visual cues, and a method of performing visual-cue operation. In a computer system having a central processing unit (CPU), and memory, a data-storage device, and an interface for receiving, interpreting and executing commands formulated by a user, a camera is positioned to allow the user to enter its visual field. To remotely operate the computer, the user performs a predetermined motion or series of motions while in the camera'"'"'s field of view. The camera captures an image of the user and digitized the image into a video data stream. A video processor monitors the video data stream for indications that the user has entered a visual cue by performing a prescribed motion. When a visual cue is recognized, the video processor then generates a command set corresponding to the recognized cue. The command set then presented to the computer'"'"'s command processor for execution. Ease of use for the visual cue interface is enhanced by using the computer'"'"'s graphical display to superimpose a command template over the image of the user being captured by the camera.
