Claim Text:
1. An electronic stylus and a capacitive sensing touch-screen electronic device system comprising: an electronic stylus having a generally cylindrical housing having a first end and a second end; a touch-screen electronic device having an illuminating device located therein; a metallic object secured to and located near the first end of the generally cylindrical housing of the electronic stylus wherein the metallic object is capable of emitting a plurality of electrons when struck by a light incident generated by the illuminating device located within the touch-screen of the electronic device; wherein there is no physical permanent connection between the electronic stylus and the touch-screen electronic device having the illuminating device; wherein the illuminating device produces a light incident which strikes the metallic object and energizes the metallic object and causes the metallic object to eject electrons therein forming a non-uniform electric field near the metallic object; and wherein the non-uniform electric field created by the metallic object therein is detected by a capacitive sensing electronic touch-screen device and wherein the capacitive sensing electronic device may be operated and controlled by movement of the non-uniform electric field surrounding the metallic object.
