Abstract
A portable information handling system integrates a keyboard having plural sensors configured at each of keyboard key positions to detect key inputs made with presses at the key positions by deflection of a glass cover having a reduced thickness at each key position. Haptic devices, such as piezo actuators, actuate at sensor sensed inputs to reinforce end user input touch feedback over the feedback provided by deflection of the glass cover. In one embodiment, the plural sensors are incorporated in a membrane having OLED illumination that identifies the key value at each key position.
