Abstract:
In one embodiment, a touch screen device includes a controller, a force sensing layer, a cushion layer, and a reference layer. The controller includes a processor to determine a distance between the force sensing layer and the reference layer. The cushion layer is between the force sensing layer and the reference layer. The cushion layer may include a plurality of holes at selected locations devoid of material of which the cushion layer is made. The reference layer may include a plurality of raised areas at selected locations.
