Stylus with control ring user interface

摘要

Control rings 106 and 108 are mounted on the body 104 of a stylus 100. A controller 202 within the stylus body 104 generates a control signal 500 dependent upon the control rings. The control signal 500 is transmitted to a host electronic device 120 where information contained in the control signal 500 is used to control properties of a drawing tool in a computer drawing application.
