Abstract

We discuss a pointing system, the viewing tablet, that enables input or instructions to be given to information system by the operator viewing a sheet object and pointing out its position in the field of vision. The operator has a small video camera that picks up an image of the partial area including the viewing position and points out an object in the field of vision. The viewing tablet processes the partial area image on the object including the viewing position to detect the position in a part pointed out with a finger and gives input or instructions to information system. A transparent space code sheet is overlapped for use that is added with position information on the sheet object to determine the position in the object from the partial area image. We studied the basic technique required for this pointing system and confirmed its feasibility.
