<p>A system for tracking a spatially manipulated user controlling object using a camera associated with a processor. While the user spatially manipulates the controlling object, an image of the controlling object is picked-up via a video camera, and the camera image is analyzed to isolate the part of the image pertaining to the controlling object for mapping the position and orientation of the device in a two-dimensional space. Robust data processing systems and computerized method employing calibration and tracking algorithms such that minimal user intervention is required for achieving and maintaining successful tracking of the controlling object in changing backgrounds and lighting conditions.</p> |
