Abstract: The present device provides for a universal stylus. The stylus emits a light incident upon a distal metallic object therein causing electrons on the metallic object to be ejected from the metallic object, resulting in a non-uniform electric field near the metallic object. When the metallic object is brought into close proximity of a capacitive touch-screen of a smartphone, tablet, kiosk, computer or other electronic device, the local disruption in the electric field surrounding the touch-screen is registered as a touch, in a similar manner as a human finger normally activates the touch-screen. In an embodiment, the device utilizes a light incident directly upon the electronic device, without the need for the light incident striking a metallic object.
