EASILY DEPLOYABLE INTERACTIVE DIRECT-POINTING SYSTEM AND PRESENTATION CONTROL SYSTEM AND CALIBRATION METHOD THEREFOR
First Claim
1. A method for controlling a parameter related to a position of a computer display cursor based on a point-of-aim of a pointing device within an interaction region, comprising:
- projecting an image of a computer display to create the interaction region;
establishing at least one calibration point having a predetermined relation to said interaction region;
directing a pointing line to substantially pass through said calibration point while measuring a position of and an orientation of the pointing device, said pointing line having a predetermined relationship to said pointing device; and
controlling the parameter related to the position of the cursor within the interaction region using measurements of the position of and the orientation of the pointing device.

Abstract
A method for controlling movement of a computer display cursor based on a point-of-aim of a pointing device within an interaction region includes projecting an image of a computer display to create the interaction region. At least one calibration point having a predetermined relation to said interaction region is established. A pointing line is directed to substantially pass through the calibration point while measuring a position of and an orientation of the pointing device. The pointing line has a predetermined relationship to said pointing device. Movement of the cursor is controlled within the interaction region using measurements of the position of and the orientation of the pointing device.
