Abstract :
This paper describes the new input system for data tablet based on the observation of handwriting by CCD camera. The system takes the pen movement on the writing plane with 64 gray level sequential images. As the system needs 0.25 sec. for one frame image, we can observe the slow handwriting by this system. The CCD camera takes the sequential images written on the writing pad with a 50×50 mm frame. After that, the system can extract the online stroke data, that is, the sequential position coordinates from the sequential input images. We can perform the style of the data tablet without sensor table and wired stylus pen. This system is useful for a new data tablet based human friendly input device
