6. An input device as claimed in claim 4 wherein a number of pushbuttons are mounted below said ring said pushbuttons being actuated by pressing the hand griply toward one or more of the pushbuttons to translate the orthogonal displacement of said ring into signals indicative of respective data inputs.

7. An input device as claimed in claim 1 wherein said signals cause movement of a cursor on a display.

8. An input device as claimed in claim 1 wherein said moveable element is a first moveable element which is capable of displacement relative to a second moveable element and the axes of rotation of said first and second moveable elements are parallel and the relative displacement between said first moveable element and said second moveable element is translated into one of the signals indicative of said respective data input.

9. An input device as claimed in claim 8 wherein the axes of rotation of said first and second moveable elements are congruent.

10. An input device as claimed in claim 1 wherein the mutually orthogonal movements of said first moveable element are translated into signals indicative of movement in polar co-ordinates.

11. An input device as claimed in claim 1 said device is placed on the handgrip of said vehicle steering wheel.

12. An input device as claimed in claim 1 wherein functions can be selected by pressing said first moveable element.

13. An input device for providing data input for use with a vehicle steering wheel having an axis of rotation, wherein the input device is fixed to the vehicle steering wheel, comprising:
