Abstract
An apparatus for indicating the position of an object in a three dimensional space is described. The apparatus includes a video arrangement for producing a stereoscopic image of a scene including the object. Overlay generators superimpose on this image a stereoscopic image of a cursor. Cursor control means are provided for varying the apparent position of the cursor in the scene and for providing an output representing the apparent position of the cursor.
