Pointing device and cursor for use in intelligent computing environments
First Claim
1. A computer-readable medium having computer-executable instructions for directing a laser beam within a space to act as a cursor or laser pointer, said computer-executable instructions comprising:
- receiving movement control commands generated by a movement control device each of which specifies the direction the laser beam is to be pointed, and directing a laser beam generated by a cursor device to move about the space as specified by the movement control commands, wherein the laser beam movement varies between a fast motion mode and a slow motion mode depending on the current speed of the laser beam.

Abstract
A system and process for directing a laser beam within a space is presented. The system includes a pointing device which periodically outputs orientation data indicative of the direction it is pointing and a cursor device which projects a laser beam. The orientation data is used to compute the direction the pointing device is pointing in terms of yaw and pitch angles. The laser beam is directed to locations in the space relative to the amount of movement of the pointing device. In an absolute mode, the pointed device and the laser beam of the cursor device are pointed at the same location in the space, whereas in a relative mode, the pointing device does not point at the same location as the laser beam. The position of the laser can be used to select a variety of hardware devices known to be in a room for future control actions.
