Abstract
A writing device for marking on a capacitive touch screen and a paper substrate is disclosed. The device features a writing tip deployable through a hole in a conductive rubber stylus tip. The stylus tip connects to a distal end of a shaft. The stylus tip may be held in place by a ring. Electric connection is formed from a human user, through the shaft, and to the stylus tip onto the touch screen when a sufficient contact patch if formed through pressing lightly on the stylus tip. The stylus tip may be coated with a protective material that adjusts the coefficient of friction and prevents carbon from depositing on the touch screen. The writing tip (e.g., pen or pencil) moves from a working position where it extends through a hole in the stylus tip to a position where it is disposed within a hollow cavity formed by the stylus tip.
