Abstract

An acoustic mouse system is described that controls indications on an X-Y surface of the face of a display. The system comprises a support for holding at least three acoustic receivers in an x-y plane, and a hand movable acoustic transmitter that is movable both parallel to the x-y plane and in a z direction perpendicular to the x-y plane. The transmitter generates periodic acoustic oscillations in the direction of the support and its receivers. Detection circuitry, responsive to signals from the acoustic receivers, provides signals indicative of the absolute position of the acoustic transmitter in the x-y plane. A processor is responsive to the signals from the detection circuitry to provide absolute position signals to the display, whereby the display responds by moving an indication to a corresponding position on the X-Y surface of the display face. The detector circuitry is further enabled to provide z position signals to the display, whereby the display may modify a display function in accordance with the z position signals.

Claims

1. An acoustic mouse system for controlling indications on an X-Y surface of the face of a display, the system comprising:

support means for holding at least three acoustic receivers in an x-y plane;

hand movable, acoustic transmitter means movable in said x-y plane and in a z direction perpendicular to said x-y plane, for generating a periodic acoustic oscillations in the direction of said support means;

detector means, responsive to outputs from said acoustic receivers, for providing signals indicative of the absolute position of said transmitter means in said x-y plane and in said z direction; and

processor means responsive to said signals from said detector means for providing position signals to said display, whereby said display responds to signals indicative of the absolute position of said transmitter means in said x-y plane by moving a displayed indication to a corresponding position on the X-Y surface of said display face, said display further responding to a z position signal from said processor means by altering an indication on said display.

2. The acoustic mouse system of claim 1, further comprising:

switch means for selectively enabling said mouse system to pass to said display, a z position signal indication.

3. The acoustic mouse system of claim 2 wherein said position signals provided by said processor means indicate absolute x and y positions of said transmitter means.
