METHOD FOR CORRECTING COORDINATION OF ELECTRONIC PEN AND POTABLE ELECTRONIC DEVICE SUPPORTING THE SAME

摘要

According to the present invention, an electronic pen correcting method, using a portable electronic device and an electronic pen including a coil and a pen contact part separated at a distance, includes: a process of calculating a coordinate correction angle; and a process of calculating a coordinate correction distance, from an electromagnetic induction point on a display part of the portable electronic device in which a magnetic field generated by the inter-sensor board electromagnetic induction of the portable electronic device and the coil, to a contact point of the pen contact part to the display part. The coordinate correction angle calculating process includes at least one process among a process of calculating the coordinate correction angle by using the electromagnetic induction point and a left and right inclination degree of the portable electronic device around the front of a user based on a user face image; a process of calculating the coordinate correction angle by using the electromagnetic induction point and a point on the display part corresponding to touch hovering input generated on the display part by the hand hovering of the user holding the electronic pen; and a process of calculating the coordinate correction angle by using the electromagnetic induction point and a point on the display part corresponding to palm touch input generated by a palm touch of the user to the display part.
