An input device 10, such as a mouse, comprises a panning mechanism 12. The panning mechanism comprises a sensor arrangement having first and second sensor components 46, 48, a movable carrier arrangement 40 for carrying the first sensor component and a fixed carrier arrangement 42 on which the second sensor component is mounted. The movable carrier arrangement 40 is movable relative to the fixed carrier arrangement 42. The panning mechanism 12 further includes constraining means 50 to constrain movement of the movable carrier arrangement 40 relative to the fixed carrier arrangement 42 in two directions. The movement of the movable carrier arrangement 40 relative to the fixed carrier arrangement 42 effects movement of the first sensor component 46 relative to the second sensor component 48 to create input signals such as input signals for a data processing apparatus. The input device may further comprise a twisting mechanism 14, whereby pivoting movement creates input signals. The input device may further comprise a tilting mechanism 16, whereby pivoting about a tilt axis creates input signals. |
