Cursor control device for controlling a cursor on a computer screen includes a base having a flat lower surface to enable it to be movable over a horizontal surface, a pliable casing defining an interior, and a fluid-containing bladder arranged inside the casing interior and to change its shape upon application of pressure to an outer surface of the casing. When a user grasps the casing in their hand and squeezes it, the casing and the bladder change their shape. A mechanism is arranged in connection with the base for responding to the change in shape of the bladder and generating signals for control of a cursor based thereon. One embodiment of the mechanism may include a switch which can extend upward from the base through a channel in the casing so that the bladder enters into this channel as it changes its position and thereby actuates the switch. |
