Abstract

In one aspect of the invention, a display device is provided. The display device comprises a body having an opening to a display receiving area. A display is joined to the display receiving area and a generally transparent contact element positioned between the opening and the display. At least two force sensitive elements are between the contact element and the display receiving area, and each force sensitive element is adapted to generate a signal when a force has been applied to the contact element. A controller receives the signals and determines a user input action based upon the signals received. The force sensitive elements are adapted to detect the application of force along different axes and to generate signals that the controller can use to determine when a force has been applied to the contact element and along which of the different axes the force has been applied.
