Abstract
A user input system including a stylus and an electronic device. A user may manipulate the stylus across an input surface of the electronic device and the movement may be detected using axially-aligned electric fields generated by the stylus. The stylus may also include a force-sensitive structure that can be used to estimate a force applied to the electronic device by the stylus.
