A touchpad- or touch screen-based device has a touch-sensitive sensor surface and can generate electrical and/or optical signals dependent on the placement and/or movement of a finger physically contacting the sensor surface. The sensor surface comprises a corrugated surface in at least one sub-area, thereby providing a user with two modes for finger movement across the sensor surface, namely a first mode for sliding movement at a first finger pressure, and a second mode for guided movement at a second finger pressure higher than the first finger pressure. |
