Handwriting input device

Abstract

A handwriting input device, including a display component, a magnetic signal sensing component arranged at a random position on the display component, and a magnetic signal output component arranged corresponding to the sensing component, wherein the display component, the sensing component and the output component are all arranged in a shell, and the shell is further includes a mainboard, wherein the sensing component includes a sensing element and a detection control circuit connected with the sensing element; the sensing element includes a horizontal and a vertical encoding array; and both the horizontal and the vertical encoding arrays consist of magnetic signal sensing coil units. The handwriting input device aims at solving the problems of long detection time, slow reaction speed, low positioning sensing precision, big long-distance movement accumulative error and complicated device of the magnetic sensing devices in the prior art.
