Abstract
A stylus includes an elongated housing, a tip extending from a first end of the elongated housing and a tri-axial force sensor mounted on a second end. A first wireless transmitter transmits a signal via the tip based on which the tip interacts with a digitizer sensor of a touch screen. The tri-axial force sensor senses contact force applied by a user pressing against the tri-axial sensor. A second wireless transmitter transmits output sensed by the tri-axial force sensor. The stylus further includes a controller that controls transmission of the first wireless transmitter and the second wireless transmitter.
