The present invention relates to a keyboard with a plurality of sensitive key elements (10, 12, 14) arranged on said keyboard according to a predetermined scheme. Each of the key elements (10, 12, 14) provides an analogue electric signal (U1, U2, U3). The analogous electric signal (U1, U2, U3) depends on the position of a fingertip. A contact surface of the key element (12) 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 (10, 14). Each zone (A, B, C, D) corresponds with a range of relationships between the signal (U2) of the key element (12) and the signal (U1, U3) of at least one adjacent key element (10, 14).

La présente invention porte sur un clavier avec une pluralité d'éléments de touche sensibles (10, 12, 14) agencés sur ledit clavier selon un schéma prédéterminé. Chacun des éléments de touche (10, 12, 14) fournit un signal électrique analogique (U1, U2, U3). Le signal électrique analogique (U1, U2, U3) dépend de la position d'une extrémité de doigt. Une surface de contact de l'élément de touche (12) est sous-divisée en zones (A, B, C, D). Les zones (A, B, C, D) sont définies de telle sorte que les zones (A, B, C, D) ont différentes distances à partir des éléments de touche adjacents (10, 14). Chaque zone (A, B, C, D) correspond à une plage de relations entre le signal (U2) de l'élément de touche (12) et le signal (U1, U3) d'au moins un élément de touche adjacent (10, 14).
