Abstract
The present invention relates to a handwriting input pen which is completely different from the existing various handwriting input methods. An action sensor is used for converting a writing action into an electric signal so as to detect and know the motion state of the pen. With the present invention, a user can write on any object, even in the air. The present invention can be used in an off-line (computer disengagement) way. When the handwriting input pen is applied to a signature authentication device, because the dynamic information of an action can not be seen, a signature is difficult to simulate and can not be obtained in a verbal way or a written form way. Therefore, secrecy can not be divulged. If the present invention is positioned on a miniature operating lever, a 'action coded lock' can be made. The present invention can also be used as a joystick for three-dimensional games or an input device for the dumb language. If placed on limbs, the 'wireless emission pen' can detect and know the variation of parameters of postures of an athlete; if placed on a human body, the 'wireless emission pen' can be used for playing electronic musical instruments or controlling other electrically driven devices by actions.
