Abstract
A touch screen overlay apparatus for use in association with a touch screen having a rigid contact surface. The touch screen overlay apparatus comprises a flexible membrane that covers at least a portion of the rigid contact surface. This flexible membrane is removably maintained in a predetermined position over the rigid contact surface to provide a more tactually desirable surface for manual actuation than the rigid contact surface. Furthermore, the flexible membrane may include one of said one or more raised dome-shaped regions which are disposed on the membrane so as to be in substantial registration with input regions on the rigid contact surface to provide tactile landmarks for the user.
