The 3D air-mouse you wear as a ring

The MagicMouse is a true 3D mouse. Users can move the cursor about the screen simply by pointing and moving their index finger. Zooming is achieved by moving the hand nearer to or farther from the screen. Since both actions can be done simultaneously, the mouse makes it possible to work easily in three dimensions to pan and zoom through 3D maps, for example, or manipulate objects in computer-aided design (CAD) drawing packages.
