Abstract

Un dispositivo di controllo del cursore per personal computer e postazioni di lavoro comprende una sfera maculata casualmente e illuminata con luce diffusa. Un'immagine di almeno una porzione della superficie illuminata della sfera maculata viene messa a fuoco da un elemento ottico come ad esempio un elemento ottico a diffrazione su una schiera di fotosensori. La logica associata alla schiera di fotosensori determina il movimento della sfera rispetto alla schiera, e traduce detto movimento in segnali di controllo del cursore convenzionali forniti ad un sistema host.(FIG. 2a).
