An input device includes a touch sensor and a processing unit. The touch sensor has a surface and is configured to sense an imprint of a finger that touches the surface. The processing unit is configured to calculate a tilt of the finger relative to the surface by measuring a shift of the imprint sensed by the touch surface, and to produce an output based on the tilt.
