## Abstract

There is provided a system and method for a pressure and angle sensitive stylus device. The method comprises detecting a plurality of pressure inputs using a plurality of sensors, determining an angle of pressure applied to a stylus device from the plurality of pressure inputs, and transmitting the angle of pressure to an interactive device. The plurality of sensors may be recalibrated when the plurality of sensors are not in use. Further, using the plurality of pressure inputs may detect a velocity of usage of the stylus device. The plurality of sensors may include three sensors arranged in a radially symmetric pattern about a longitudinal axis of the stylus device.
