FIELD: information technology.
SUBSTANCE: user input device for an electronic device includes a haptic feedback layer and a touch sensitive user interface. The haptic feedback layer includes a chassis and a plurality of oppositely facing, interlaced cantilever beams emanating therefrom, further separated by a support beam, and spanning at least a portion of the haptic feedback layer. One or more piezoelectric actuators are connected to the cantilever beams and are controlled by a controller. When the controller detects user actuation of the touch sensitive user interface, the controller causes at least one of the piezoelectric actuators to actuate in accordance with an actuation signal.
EFFECT: providing active haptic feedback for a user.
