Abstract
The present invention relates to a keyboard with a plurality of sensitive key elements () arranged on said keyboard according to a predetermined scheme. Each of the key elements () provides an analogue electric signal (UUU). The analogous electric signal (UUU) depends on the position of a fingertip. A contact surface of the key element () is subdivided into zones (A, B, C, D). The zones (A, B, C, D) are defined in such a way, that the zones (A, B, C, D) have different distances from the adjacent key elements (). Each zone (A, B, C, D) corresponds with a range of relationships between the signal (U) of the key element () and the signal (UU) of at least one adjacent key element ().
