Abstract
Human-computer interface devices are described in the present disclosure. In one embodiment, among several embodiments, a human-computer interface includes a display device configured to visually display images to a user and a touch sensitive device configured to sense contact with the user. Furthermore, the human-computer interface includes a composite piezoelectric layer positioned between the display device and the touch sensitive device. The composite piezoelectric layer is configured to provide haptic feedback to the user.
