ABSTRACT:
The invention provides a holder for a position indicator device used to position a cursor on a visual display. The holder comprises a rectangular base member having rotatably-mounted ball bearings and apertures adapted to allow the spherical transport ball of the position indicator device to come in contact with a supporting surface. When the holder is coupled to the position indicator, only the ball bearings and transport ball make contact with the supporting surface, thereby providing for smoother and faster movement of the position indicator and correspondingly more accurate positioning of the associated cursor.
