Patent Images
1. A method for controlling a location of a pointer displayed by a pointing device on a display surface, comprising:
- determining a current virtual location of a virtual pointer displayed on a display surface by a pointing device;
determining a next physical location of the virtual pointer according to a pose of the pointing device;
determining a distance between the current virtual location and the next physical location;
comparing the distance to a plurality of predetermined thresholds; and
moving the virtual pointer based on a numerical relationship between the distance and the predetermined thresholds.

Abstract
The invention provides a method to stabilize a pointer displayed within an output image. The method enables the user to magnify selected areas within the output image. This allows the user to ‘zoom’ in on areas of interest in the output image, and to make accurate selections with the stabilized pointer. Design features of the method enable pixel and sub-pixel accurate pointing, which is not possible with most conventional direct pointing devices. The invention can be worked for 2D and 3D pointers.
