Abstract:
A reconfigurable haptic interface assembly of an information handling system may comprise a coversheet display layer displaying a key location of a haptic keyboard based on a modified configuration, a contact foil placed between the coversheet layer and a support layer, and a piezoelectric element placed between the contact foil and the support layer receiving an applied mechanical stress near the displayed key location, and transmitting a generated piezo actuation signal via the contact foil. A processor may receive the piezo actuation signal, identify x- and y-coordinate location data describing the displayed key location based, in part, on the piezo actuation signal, identify a keyboard scan code associated with the x- and y-coordinate location data, and send a haptic feedback response signal to the piezoelectric element to generate a haptic feedback at the key location and a digital display may display a key register event.
