Abstract
An intelligent stylus is disclosed. The stylus can provide a stylus condition in addition to a touch input. The stylus architecture can include multiple sensors to sense information indicative of the stylus condition, a microcontroller to determine the stylus condition based on the sensed information, and a transmitter to transmit the determined condition to a corresponding touch sensitive device so as to cause some action based on the condition.
