Abstract

The system provides a gestural interface to various visually presented elements, presented on a display screen or screens. A gestural vocabulary includes ‘instantaneous’ commands, in which forming one or both hands into the appropriate ‘pose’ results in an immediate, one-time action; and ‘spatial’ commands, in which the operator either refers directly to elements on the screen by way of literal ‘pointing’ gestures or performs navigational maneuvers by way of relative or “offset” gestures. The system contemplates the ability to identify the users hands in the form of a glove or gloves with certain indicia provided thereon, or any suitable means for providing recognizable indicia on a user'"'"'s hands or body parts. A system of cameras can detect the position, orientation, and movement of the user'"'"'s hands and translate that information into executable commands.

Claims

1. A method of controlling a computer display comprising:

detecting a physical control gesture made by a user;

translating the control gesture to an executable command;

updating the computer display in response to the executable command.
