Abstract:
1. A handwriting recognition device, comprising: a main body, the main body comprising a side surface and an operation surface perpendicularly connecting to the side surface; 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 extending to perpendicularly cross a second optical axis of the second camera module outside the side surface, wherein the first optical axis and the second optical axis cooperatively define a Cartesian coordinate system that takes the first optical axis as the x-coordinate and the second optical axis as the y-coordinate, 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, and the second lens module is configured to capture a second picture of the handwriting tool in the input area; and a controller configured to calculate coordinates of the handwriting tool in the Cartesian coordinate system according to the first picture and the second picture.
