Stylus for coordinate measuring

Abstract:

An input device, such as a hand-held, wireless stylus, can be used to measure coordinates of a three-dimensional object. Position data can be calculated based on, for example, acceleration, orientation, and static parameters of a stylus. As the stylus contacts contours of the object, the position data of the stylus can allow mapping of the object as well as digital rendering thereof. The stylus can also be used to virtually create three-dimensional illustrations.
