Abstract

An user interface for accepting three dimensional information (such as x, y and z axis positioning information) for input into a computer, printer, copier or other electronic device. In addition to indicating the x and y axis position coordinates of the input, the input pad of the user interface also registers a z axis coordinate based on the pressure applied by the operator on the outer surface of the input pad. This z axis force component is enabled by the force sensing layers of parallel conductors in the input pad.
