Abstract
An apparatus structured as a writing instrument and providing the functionality of a writing instrument such as a pen, with additional functionality including that of a joystick, a mouse, a stylus, or a keyboard. One embodiment of the writing instrument structure includes piezoelectric sensors for measuring force of the writing instrument against a surface in three directions, acceleration of the writing instrument in three directions, tilt of the writing instrument two directions, magnetic field surrounding the writing instrument in two directions, and energy dissipation during a motion or sequence of motions. The various measurements can allow for reconstruction of the writing instrument motion, thereby allowing control of other devices. The biometric data can be combined with other data to provide inputs to a biometric authentication system including a signature verification system.
