Abstract

A pointing device with independently movable portions is described. In an embodiment, a pointing device comprises a base unit and a satellite portion. The base unit is arranged to be located under a palm of a user'"'"'s hand and be movable over a supporting surface. The satellite portion is arranged to be located under a digit of the user'"'"'s hand and be independently movable over the supporting surface relative to the base unit. In embodiments, data from at least one sensing device is read, and movement of both the base unit and the independently movable satellite portion of the pointing device is calculated from the data. The movement of the base unit and the satellite portion is analyzed to detect a user gesture.

Claims

1. A pointing device, comprising:

a base unit arranged to be located under a palm of a user'"'"'s hand and be movable over a supporting surface; and

a satellite portion arranged to be located under a digit of the user'"'"'s hand and be independently movable over the supporting surface relative to the base unit.

2. A pointing device according to claim 1, wherein the satellite portion comprises a movement sensor arranged to generate a data sequence relating to sensed movement of the satellite portion relative to the supporting surface.

3. A pointing device according to claim 1, wherein the satellite portion is tethered to the base unit.

4. A pointing device according to claim 3, wherein the satellite portion is tethered to the base unit via an articulated member.

5. A pointing device according to claim 4, wherein the base unit comprises a movement sensor connected to the articulated member such that the movement sensor is arranged to generate a data sequence relating to the position of the satellite portion relative to an inside surface of the base unit.

6. A pointing device according to claim 1, wherein the base unit comprises a movement sensor arranged to generate a data sequence relating to sensed movement of the base unit relative to the supporting surface.

7. A pointing device according to claim 1, wherein the base unit comprises a sensing device arranged to generate a data sequence relating to the position of the satellite portion relative to the base unit.

8. A pointing device according to claim 1, further comprising a further satellite portion arranged to be located under a further digit of the user'"'"'s hand and be independently movable over the supporting surface relative to the satellite portion and the base unit.

9. A pointing device according to claim 1, wherein the satellite portion comprises a haptic feedback actuator arranged to provide haptic feedback to the digit of the user'"'"'s hand responsive to a command signal.

10. A pointing device according to claim 1, wherein the pointing device comprises a force feedback actuator arranged to influence movement of the satellite portion by the digit of the user'"'"'s hand responsive to a command signal.

11. A pointing device according to claim 1, wherein the base unit comprises a first conductive portion at its periphery and the satellite portion comprises a second conductive portion at its periphery, and the pointing device is arranged to detect contact between the first conductive portion and second conductive portion.

12. One or more tangible device-readable media with device-executable instructions for performing steps comprising:

reading data from at least one sensing device;

calculating movement of a base unit of a pointing device from the data;

calculating movement of an independently movable satellite portion of the pointing device from the data; and

analyzing the movement of the base unit and the satellite portion to detect a user gesture.

13. One or more tangible device-readable media according to claim 12, further comprising device-executable instructions for controlling a software program in accordance with the user gesture detected.

14. One or more tangible device-readable media according to claim 12, wherein the steps of calculating movement of the base unit and calculating movement of the independently movable satellite portion are performed substantially concurrently.

15. One or more tangible device-readable media according to claim 12, wherein the movement of the base unit and the movement of the satellite portion is relative to a supporting surface, and the one or more tangible device-readable media further comprises device-executable instructions for controlling the position of a cursor in a user interface in accordance with the movement of the base unit relative to the supporting surface and the movement of the satellite portion relative to the supporting surface.

16. One or more tangible device-readable media according to claim 15, wherein the movement of the base unit and the satellite portion together relative to the supporting surface causes a larger displacement of the cursor than a corresponding movement of the satellite portion alone relative to the supporting surface.

17. One or more tangible device-readable media according to claim 12, further comprising device-executable instructions for calculating a position of the satellite portion relative to the base unit.

18. One or more tangible device-readable media according to claim 17, wherein the step of calculating the position of the satellite portion relative to the base unit comprises using the movement calculated for the satellite portion to track the position of the satellite portion from an initial known location.

19. One or more tangible device-readable media according to claim 17, wherein the at least one sensor comprises one of a camera and an absolute position sensor arranged to determine the position of the satellite portion relative to the base unit, and the step of calculating the position of the satellite portion relative to the base unit comprises reading satellite portion position data from the at least one sensor.

20. A computer mouse device, comprising:

a base unit arranged to be located under a palm of a user'"'"'s hand and be movable over a supporting surface;

a satellite portion tethered to the base unit, and arranged to be located under a digit of the user'"'"'s hand and be independently movable over the supporting surface relative to the base unit;

a sensing device arranged to generate a data sequence relating to sensed movement of the base unit; and

a further sensing device arranged to generate a further data sequence relating to sensed movement of the satellite portion.
