ABSTRACT:
The present invention provides a cursor control device for use in three dimensional space. The cursor control device is based on point and click technology such that a user points a remote member of the cursor control device to a television assembly and depresses appropriate keys for corresponding functions. In particular, a mouse key on the remote member enables control of cursor movement functioning of a cursor displayed through the television assembly. A base unit portion of the present invention device is coupled to or interfaced with the television assembly. The base unit provides an ultrasound source for use of ultrasound by the remote member for determining positioning angular orientation of the remote member in three dimensional space. The base unit includes an infrared receiver for receiving infrared signals generated by an infrared transmitter at the remote member. Mouse commands and other commands from the remote member are communicated through infrared signals to the base unit.
