ABSTRACT:
Cursor control device for controlling a cursor on a screen of a computer includes an outer casing, an inner casing arranged inside the outer casing, a sensor arrangement for detecting application of pressure to the outer casing above a pre-determined magnitude, and hardware coupled to the sensor arrangement for converting the application of pressure to the outer casing into signals indicative of the application of such pressure. These signals are provided by the hardware to a computer having a screen with the cursor thereon to enable control of the cursor. The sensor arrangement may include a conductive mesh on an inner surface of the outer casing and a conductive covering on the outer surface of the inner casing with a space being present therebetween. Squeezing the outer casing causes the conductive mesh to contact the conductive covering thereby completing an electrical circuit which is detected by the hardware.
