Abstract
A force-based haptic switch panel, comprising a touch plate having first and second surfaces, the first surface comprising a touch surface and the second surface opposing the first surface. The haptic switch panel may also comprise a circuit board having a plurality of force sensors electrically coupled thereto. The force sensors are disposed between the circuit board and the second surface of the touch plate, wherein each force sensor is configured to measure a respective portion of a force applied to the touch surface of the touch plate. The haptic switch panel may also comprise an acoustic actuator disposed proximate a second surface of the touch plate and configured to generate a haptic output and an audible output responsive to the force applied to the touch surface.
