Abstract
Abstract A wireless control device includes a small, lightweight housing worn by an operator, for example on the operator's wrist, and a controlled device, for example a personal computer. Several optical emitters, preferably light emitting diodes operating in the infrared range, and several optical detectors are provided on the housing. At least one x-axis emitter-detector pair operates to detect an x-direction of a pointing motion or gesture, and at least one y-axis emitter-detector pair operates to detect a y-direction of a pointing motion or gesture. This motion can then be used to cause a response in the controlled device. For example, angles of the operator's hand at the wrist can be interpreted to induce motion of a cursor on a computer display. The device may also include a motion sensor, an environmental condition sensor, or a voice recognition sensor, and can also be adapted for gesture recognition and image scanning applications.
