Le processeur (20) traite le signal de détection de course de déplacement de la poignée via des programmes et des circuits logiques et émet le signal traité à l'organe de surveillance. La touche de commutation de mode (30) effectue la commutation de mode pour permettre au processeur d'identifier la sélection de l'organe de saisie sous forme de lettres/chiffres/symboles. L'organe de surveillance (40) affiche séparément le signal traité, les lettres/chiffres/symboles pré-stockés et une carte de déplacement de la poignée correspondant à ces lettres/chiffres/symboles.
