Description of the invention (1)-[Technical field to which the invention belongs] The present invention relates to an electromagnetic induction system, and more particularly, to an electromagnetic induction system and method for optimizing antenna circuit layout. 2. [Because it is suitable for writing identification, handwriting recognition, and upgrading users to replace the traditional mouse. The traditional pen is available for drawing or system. There are two pairs of patterns in public places. The board table can identify the mouse number. This pair, in the digital pair mode, the technology of handwriting the user ’s circuit device circuit installation operation by hand in front of the digital tablet table, and the general input type is Chinese. The improvement is equipped with manual input, visual convenience, and often electromagnetic products have been implemented. In recent years, a single board, such as a mouse or a pen that has been used for many years, is usually a pen. Point device operation mode. When the mouse is sliding on the surface of the general mouse device, the electric mouse operates in an X- and Y-direction with a signal-to-board system. The other position on the surface should be the cursor in the slide. If you raise a vertical device that shapes the mouse with the opposite of the brain system, the cursor is used to replace the mouse, enter text and rapidly develop the mouse with a pen.
