The invention relates to an input device (10), especially a keypad for a mobile telephone. The information ("t", "u" or "v") associated with the pressure of a key (12) depends on the angle at which the phone is held. Improvements of the invention include, inter alia, the fact that the association depends on the change of angle and is programmed by means of a teach-in process, an alarm function is integrated for protection against theft, and/or a step counter is integrated. |
