Abstract
An integrated, surface-mount pointing device for controlling the movement of an object on a display screen, comprises a base member mounted to a substrate; a shaft mounted in the base member; a sensor mounted on the shaft for sensing the amount of strain in the shaft in response to an applied force on the shaft; and an integrated circuit mounted between the base member and the substrate. The integrated circuit can provide signal conditioning and analog to digital signal conversion as required. This allows for an integrated and compact pointing device.
