Abstract
A drawing stylus that transmits data to a base unit using high-frequency audio or radio frequency signals is described. The stylus includes a color selector that enables a user to select a color to be associated with inputs from the stylus. A pressure sensor is also included to detect a pressure applied to the tip of the stylus. The selected color and pressure data are transmitted over high-frequency audio or radio frequency signals to a base unit for processing. The base unit may use the data received via the transmission along with one or more other data elements as inputs to an application executing on the base unit.
