Abstract: A haptic keyboard of an information handling system may comprise a coversheet to identify a key location, a support layer, a contact foil placed between the coversheet and support layer, and a controller operatively coupled to the contact foil. The controller may receive a haptic actuation indicator signal via a processor or via the contact foil, send a first haptic feedback control signal to a first piezoelectric element to cause the first piezoelectric element to generate haptic tactile movement feedback at the key location, and send a second haptic feedback control signal to the first or a second piezoelectric element to cause the second piezoelectric element to generate haptic sound feedback in response to the haptic actuation indicator signal.
