Abstract
An input system for a TV remote control or other system has a single touch surface with a deformable haptic assembly below the touch surface such that a user placing a finger on the touch surface can feel deformation of the haptic assembly. A pressure sensing assembly is below the haptic assembly and sensing motion of a finger on the touch surface, with a processor receiving input from the pressure sensing assembly and providing output to the haptic assembly in response. Also, a display receives input sent by the processor in response to input from the pressure sensing assembly to cause the display to present a changing image of a keypad as a user moves a finger on the touch surface.
