Computer painting system with passive paint brush stylus

Abstract

A computer painting system is provided for a graphic computer system that has at least one touch screen apparatus and at least one display. A stylus having a tip formed of a solid piece of a resiliently compliant non-conductive material is used to apply variable pressure on the surface of the touch screen apparatus. Software executing on the computer system interprets the variable pressure applied to the surface of the touch screen apparatus and generates corresponding graphic images on the display. Preferably, the tip of the stylus is formed of a silicone material that allows the tip to easily move across the touch screen apparatus in a way that simulates a conventional painting brush stroke but without leaving a buildup of material on the touch screen apparatus. In one embodiment, the touch screen apparatus and the display are incorporated together in the same device. In another embodiment, the touch screen apparatus is a palette physically separate from the display and operably connected to the computer system.
