Abstract
Apparatus for determining the position of a cursor with respect to a floating coordinate system, such as a menu. The floating menu incorporates two sensing devices similar to that in the cursor. A processing unit determines the position of the two sensing devices and the position of the cursor with respect to a fixed coordinate system. From this data the position of the cursor with respect to the floating menu is determined.
