1. 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:
- a moveable element capable of axial rotation relative to the vehicle steering wheel, said relative rotation being substantially about said axis of rotation and capable of displacement substantially orthogonal to the direction of rotational movement;
means for detecting relative rotation and displacement of said moveable element; and
means for translating said detected rotation and displacement into signals indicative of respective data input.
