Digital pen and digital writing module

Abstract

The invention provides a digital pen and a digital writing module. The digital writing module comprises a writing medium and the digital pen. A plurality of identification points are distributed on the writing medium so as to identify every position of the writing medium. The digital pen comprises a casing, a pen refill, a camera module, a control device, a memory and an information transmission module, wherein the camera module is used for shooting an image of a moving track of a tip of the pen refill, and the control device is connected with the pen refill and the camera module. A processor of the camera module can identify the position of the tip according to the image obtained through a lens and an image sensor, and accordingly moving track information of the tip is obtained. The control device is used for controlling the camera module to shoot the image when sensing writing pressure of the pen refill. The memory is used for storing the tip moving track information obtained by the processor. The information transmission module is used for transmitting the tip moving track information to a user terminal.

Description

technical field [0001] The invention relates to a digital pen and a digital writing module using the digital pen. Background technique [0002] An existing digital pen architecture uses laser and ultrasonic modules, which makes the product manufacturing cost high, and if there is an obstruction between the pen tip and the receiver, the laser and ultrasonic will be blocked, resulting in errors in the recorded pen tip movement path data , causing the problem of data loss, which in turn leads to the regret that the product cannot be widely popularized. Contents of the invention [0003] In view of this, it is necessary to provide a digital pen and a digital writing module that can overcome the above-mentioned difficulties. [0004] A digital pen comprises a shell, a pen core is built into the shell, a camera module, a control device connecting the pen core and the camera module, a memory and an information transmission module. The pen core has a tip that can expose an end o...
