Abstract

A handwriting recognition device includes a main body having a side surface and an operation surface perpendicularly connecting to the side surface, and a first lens module and a second lens module arranged at opposite sides of the side surface. A first optical axis of the first lens module extends to perpendicularly cross a second optical axis of the second camera module outside the side surface. An overlapped area of a view angle of the first lens module and a view angle of the second lens module is defined as an input area. The first lens module is configured to capture a first picture of a handwriting tool in the input area. The second lens module is configured to capture a second picture of the handwriting tool in the input area. The handwriting recognition device calculates coordinates of the handwriting tool according to the first and the second pictures.
