Abstract

A handheld electronic device includes a housing having a surface; a first input component having input members disposed external to the surface; a second touch sensitive input component disposed about the input members, the touch sensitive input component being separate and distinct from the input members and the first input component and being structured to provide one of: a contact point with respect to the surface responsive to actuation of a first number of the input members, and a number of responses responsive to actuation of a second number of the input members. A processor cooperates with the first input component and the touch sensitive input component to determine if a plurality of the input members are actuated contemporaneously and to output a representation of a single one of the input members based upon one of: the contact point, and the number of responses.
