ABSTRACT:
Direct and absolute pointing is provided for with respect to a two-dimensional information display surface, much like how one would point a laser pointer or flashlight at a desired point. The displayed control may be moved by manipulating the pointing device in three dimensions. The translational position of the pointing device may be measured in three dimensions. Also, the three-dimensional orientation of the pointing device may be measured. A computing device may receive this information from the pointing device and determine where the pointing device is pointing to. If the pointing device is pointing at a display, then the computing device may cause the control to be displayed at the position to which the pointing device is pointing. In addition, the control may be displayed at an orientation that depends upon the orientation of the pointing device.
