    Abstract: An electronic device and corresponding method provide haptic feedback to a user. The electronic device includes a rigid input surface, a piezoelectric element directly attached to the rigid input surface, sensors disposed adjacent to the rigid input surface for sensing when the user selects various portions of the rigid input surface, the sensors providing electrical signals indicative of the selected portions, and a controller that receives the electrical signals from the sensors, and in response thereto causes drive signals to be provided to the piezoelectric element causing deformation of the piezoelectric element and bending of the rigid input surface, wherein the bending of the rigid input surface provides haptic feedback to the user in response to the user selecting of the rigid input surface.
