Le dispositif de commande (1) comprend au moins une source IR (infrarouge) (9) pour projeter le rayonnement IR (14) correspondant à l'élément de commande (5) sur l'élément de visualisation (4). Le dispositif de détection (3) comporte au moins un récepteur IR (10), le récepteur IR (10) recevant le rayonnement IR (15) réfléchi par l'élément de visualisation (4) et/ou l'objet (6). L'appareil d'évaluation (7) évalue le rayonnement IR réfléchi (15) pour générer le signal (8).
