Screen-free handwriting recognition device and recognition system thereof

Abstract

The invention discloses a screen-free handwriting recognition device and a recognition system thereof. The non-screen handwriting recognition device comprises a pen body and a pen point, the pen body is connected with the pen point through a connector slot, the pen point comprises a bidirectional potentiometer balance ring pen point used for writing on any physical plane, a first pen point is arranged at the free end of the bidirectional potentiometer balance ring pen point, a first button is arranged on the outer side face of the bidirectional potentiometer balance ring pen point, a chip processor, a power module and a first data communication module are arranged in the pen body, a first data acquisition module is arranged in the pen point, and the mobile terminal completes acquisition of original handwritten data and uploading of the data mainly through the data acquisition module and the communication module. The background screen-free handwriting recognition system is mainly used for preprocessing uploaded data and recognizing handwritings based on a deep learning network model. The method has the advantages that only the axial deviation information of the pen point needs to be collected, the collection mode is simple and effective, real available products can be conveniently formed through technology landing, and the method has a wide application scene.

Description

technical field [0001] The invention relates to the technical field of handwriting recognition, in particular to a screenless handwriting recognition device and a recognition system thereof. Background technique [0002] With the rapid development of handwriting recognition technology, tablet computers and intelligent mobile terminals with handwriting functions have become very popular in the market. Compared with the keyboard input method, the stylus input is a more direct method, which is a direct extension of the way people write Chinese characters on paper on the computer. It is more natural and more in line with the writing habits of ordinary Chinese people, and can effectively reduce the common The threshold for users to use smart devices such as computers and mobile phones.

AI Technical Summary

Problems solved by technology

[0003] Traditional handwriting input devices, such as capacitive pens or stylus pens, have the characteristics of high precision, but the handwriting input of such handwriting input devices relies on touch screens or handwriting screens. Such usage characteristics limit its usage scenarios on the one hand. On the other hand, it will also increase the manufacturing cost

And other input devices and methods based on the camera to capture the motion track of the stylus have many unfavorable factors such as illumination conditions, camera resolution requirements, and cost to limit the application of its technology. Magnetic sensor, etc.) handwriting input device and method also have limitations such as poor practical application accuracy and poor user experience

These handwriting input devices and methods all need to capture handwriting to recognize the results normally. This technical method will put forward higher requirements for the acquisition performance of the sensor.
