Abstract
A computer-input stylus which provides texture control when utilized in conjunction with a computer-implemented software-based drawing application. The input stylus includes a cylindrical body in a conical tip. A color display within the stylus is utilized to illuminate the conical tip with a color indicative of a currently selected color within the software-based drawing application, providing visual color feedback. Texture selection is accomplished utilizing a texture selection input actuator mounted to the cylindrical body of the input stylus. The texture selection input actuator, such as a trackpoint device, is utilized to vary the texture of a selected color or pattern.
