Abstract

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.

Claims

1. A cursor control device, comprising:

a base having a substantially flat lower surface to enable it to rest on and be movable over a horizontal surface;

a pliable casing defining an interior;

a fluid-containing bladder arranged inside the interior of said casing, said bladder being arranged to change its shape upon application of pressure to an outer surface of said casing; and

actuation means arranged in connection with said base for responding to the change in shape of said bladder and generating signals for control of a cursor based thereon.

2. The device of claim 1, wherein said bladder is arranged to contact said actuating means.

3. The device of claim 1, wherein said actuation means comprise a switch.

4. The device of claim 1, wherein said casing is made of a flexible material or a resilient, elastomeric material.

5. The device of claim 1, wherein said casing defines a channel at a bottom portion into which said actuation means extends, said bladder being arranged to enter into said channel when pressure is applied to the outer surface of said casing and thereby engage said actuation means.

6. The device of claim 1, wherein said casing is removable from said base.

7. The device of claim 1, wherein said casing includes a threaded portion and said actuation means includes a complementary threaded portion to enable said casing to be removably attached to said actuation means.

8. The device of claim 1, wherein said base includes an annular channel and said casing includes an annular projection arranged to fit into said annular channel to thereby secure said casing to said base.

9. The device of claim 1, wherein said bladder contains a gel.

10. The device of claim 1, wherein said casing includes a plurality of layers having different properties.

11. The device of claim 1, wherein the outer surface of said casing includes grooves for accommodating fingers of a user.

12. In a cursor control device including structure to enable the movement of the cursor control device relative to a surface on which it is being moved to be recognized, comprising:

a base having a substantially flat lower surface to enable it to rest on and be movable over a horizontal surface;

a resilient casing defining an interior;

a bladder arranged in the interior of said casing, said bladder including at least one fluid and being arranged to change its shape upon application of pressure to an outer surface of said casing; and

a switch arranged in connection with said base for responding to the change in shape of said bladder and generating signals for control of a cursor based thereon,

whereby after release of pressure to the outer surface of said casing, said casing changes toward its original shape.

13. The device of claim 12, wherein said bladder is arranged to contact said switch.

14. The device of claim 12, wherein said casing defines a channel at a bottom portion into which said switch extends, said bladder being arranged to enter into said channel when pressure is applied to the outer surface of said casing and thereby engage said switch.

15. The device of claim 12, wherein said casing is removable from said base.

16. The device of claim 12, wherein said casing includes a threaded portion and said switch includes a complementary threaded portion to enable said casing to be removably attached to said switch.

17. The device of claim 12, wherein said base includes an annular channel and said casing includes an annular projection arranged to fit into said annular channel to thereby secure said casing to said base.

18. The device of claim 12, wherein said bladder contains a gel.

19. The device of claim 12, wherein said casing includes a plurality of layers having different properties.

20. In a cursor control device including structure to enable the movement of the cursor control device relative to a surface on which it is being moved to be recognized, comprising:

a base having a substantially flat lower surface to enable it to rest on and be movable over a horizontal surface;

a resilient casing defining an interior and a channel at a bottom portion,

a bladder arranged in the interior of said casing, said bladder including at least one fluid and being arranged to change its shape upon application of pressure to an outer surface of said casing and enter into said channel defined by said casing; and

a switch arranged in connection with said base for responding to the entry of said bladder into said channel arising from the change in shape of said bladder and generating signals for control of a cursor based thereon,

whereby after release of pressure to the outer surface of said casing, said casing changes toward its original shape.
