    摘要: A stylus has a writing tip and includes a plurality of infrared transmitters configured and disposed to emit a plurality of infrared beams via that writing tip. These infrared transmitters can be disposed substantially equidistant from one another about a central axis of the writing tip and emit infrared beams at an angle that is other than parallel to that central axis. A corresponding display can detect these various beams to determine corresponding stylus-gesture information. This stylus-gesture information can comprise, for example, determining an angle of inclination of the stylus. As another example this stylus-gesture information can comprise rotation (such as a direction of rotation or the mere state of rotation) about the stylus' longitudinal axis. This stylus-gesture information, in turn, can serve as parameters to further guide or influence any of a variety of applications.
