A contact screen device, which can be connected to the serial interface, contains a touch controller, a contact sensitive unit and a display screen, on which a mouse cursor can be displayed whilst the mouse driver is active. The parameters of the touch controller are selected so that mouse compatible messages are transmitted to the computer when the contact sensitive unit is touched. The contact sensitive unit (6) contains digital resistive switching elements (DS) associated with touch controller surfaces (Ff1,Ff2) of defined size.</p> |
