ABSTRACT:
The invention relates to a display system using a remote control handunit having "pointing function" capability for moving a cursor displayed on a display screen by changing the angular position of the remote control handunit. Specifically, the individual transmitting transducers of the remote control handunit are driven with signals having a predetermined phase relationship relative to each other such that the resultant phase received by the receiver is indicative of transmitter angular position.
