Patent ID: 7218313

Claim:
A hand-held electronic device comprising: a memory configured to store a plurality of applications, wherein each application is associated with a set of functions; a processor configured to process a selected one of the plurality of applications; a first input assembly having a plurality of input elements on a first surface configured to receive input from a human user through manipulation of the plurality of input elements, wherein at least one of the input elements on the first surface is configured to selectively map to one or more input functions of the set of functions associated with the selected one of the plurality of applications; a second input assembly having one or more input elements on a second surface configured to be manipulated by one or more of the human user's fingers, wherein at least one of the input elements on the second surface is further configured to be selectively mapped to one or more input functions of the set of functions corresponding to the selected one of the plurality of applications, further wherein the plurality of input elements on the first surface and the one or more input elements on the second surface are arranged so as to substantially optimize a biomechanical effect of the human user's hand; and wherein at least one of the input elements of the second input assembly is a sensor pad configured to selectively represent a plurality of delineated active areas, wherein manipulation of a delineated active area causes the input function of one or more input elements of the first input assembly to change.
