Abstract
The present invention can include three-dimensional remote control systems that can detect an absolute location to which a remote control is pointing in first and second orthogonal axes and an absolute position of the remote control in a third orthogonal axis. Remote control systems of the present invention can employ absolute position detection with relative position detection. Absolute position detection can indicate an initial absolute position of the remote control and relative position detection can indicate changes in the position of the remote control. By combining absolute and relative position detection, remote control systems of the present invention can track remote controls more precisely than systems that only employ absolute position detection. The present invention also can include methods and apparatus for zooming in and out of an image shown on a display based on the absolute position of the remote control in the third axis.
