Handheld electronic device with touch control input module
First Claim
1. A handheld electronic device comprising:
- a case body;
a touch control input module mounted on said case body and including a protective layer having an outer surface exposed from said case body, and an inner surface opposite to said outer surface, said outer surface being defined with a plurality of contact regions, each of said contact regions being marked with a symbol, a sensing layer in contact with said inner surface of said protective layer, said sensing layer being responsive to contact of an object with said outer surface of said protective layer so as to generate an electrical output indicative of contact position of the object with said outer surface of said protective layer, and a signal processing unit coupled electrically to said sensing layer for receiving the electrical output and for generating a control output corresponding to the electrical output; and
a processing device disposed in said case body, coupled electrically to said signal processing unit, and responsive to the control output from said signal processing unit so as to perform an operation associated with the control output.

Abstract
A handheld electronic device includes a touch control input module and a processing device. The touch control input module includes a protective layer, a sensing layer, and a signal processing unit. The protective layer has outer and inner surfaces. The outer surface is defined with a plurality of contact regions, each of which is marked with a symbol. The sensing layer is in contact with the inner surface, and is responsive to contact of an object with the outer surface so as to generate an electrical output indicative of contact position of the object with the outer surface. The signal processing unit receives the electrical output, and generates a control output corresponding thereto. The processing device is responsive to the control output from the signal processing unit so as to perform an operation associated with the control output.
