Abstract
A method of and an input device for measuring scroll or click movement of an object and the input device relative to each other, includes determining the presence of the object on a window of the input device. Lower frequencies of an output signal from single sensor unit are separated and used for determining both the scroll and click motions. This allows measuring scroll movement and click movement with one sensor unit of the input device and reduction of costs and size of the input device.
