Abstract
A stylus assembly for a capacitive touch screen provides input via conventional handwriting action. A stylus is attached at a contact end to a disc providing ample capacitive proximity with the touch screen. A layer of capacitive material is embedded within the disc, and may be formed with a distinct shape, layout, or outline to provide a uniquely recognizable capacitive signature. The stylus terminates at the contact end in a received portion, attached to the disc by a receiving portion formed thereon. Free rotation of the received portion within the receiving portion accepts positioning of the stylus body at any angle with no degradation of capacitive proximity, allowing natural handwriting action. The receiving portion can be formed with sufficient flexibility to allow disengagement and re-engagement thereof, enabling simple and low-cost replacement of the disc.
