Abstract
A pressure sensitive touch pad and an overlay depicting a pattern, e.g., a typewriter keyboard, for providing specific data characteristics of the pattern to a host computer and to a specific application program of any one of a number of application programs resident in the host computer, which specific application program includes software programmed to accept configured touch pad output signals from the touch pad corresponding to the pattern, which output signals are a function of originally generated touch signals achieved by actuation, normally by touch, of the pressure sensitive overlay surface at any particular point on the pattern, which pattern on the overlay on the touch pad corresponds to and is coordinated with a specific application program in the host computer including a multitude of application programs.
