Abstract
A portable electronic device includes a touch-sensitive display and a piezoelectric actuator arranged to provide tactile feedback to the touch-sensitive display in response to an actuation signal. A pad is disposed in alignment with a force sensor such that depression of the touch-sensitive display causes the force sensor to generate a force signal. A processor configured to receive the force signal and to generate the actuation signal based on the force signal.
