An intelligent handwriting device capable of selecting an intelligent terminal

Abstract

The invention discloses an intelligent handwriting device capable of selecting an intelligent terminal. The device includes an electromagnetic screen. An electromagnetic pen synchronizes the displayinterface on the intelligent terminal to the electromagnetic screen for display and feeds back the induction signal generated by the electromagnetic screen to the first data communication interface onthe intelligent terminal. The display interface on the intelligent terminal is synchronized to the second data communication interface on the electromagnetic screen for display and the sensing signalgenerated by the electromagnetic screen is fed back to the third data communication interface on the intelligent terminal. Based on the two-wire data transmission function of the first data communication interface and the unidirectional data transmission function of the second data communication interface and the third data communication interface, By enriching the types of data interfaces of theelectromagnetic screen, not only can it be used in selective pairs with different types of intelligent terminals such as smartphones, tablets, computers, etc., which expands its application scope anduse scenarios, but also creates conditions for enhancing the portable mobile performance of handwriting devices.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to an intelligent handwriting device that can select an intelligent terminal. Background technique [0002] With the continuous advancement of science and technology, people's study and life have gradually entered the era of intelligence, and handwriting input devices, which are usually mainly used for painting creation, have also been rapidly developed and applied; at present, the existing handwriting input devices are mainly By connecting with a computer terminal device, it can play a role similar to a mouse or a keyboard, so as to complete functions such as text writing and drawing. [0003] However, the existing handwriting devices generally have the following defects: 1. The use method is single, and the existing handwriting devices generally can only be matched with computer terminal equipment (ie: PC), and cannot be compatible with smart phones, tablet computers, ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing handwriting devices generally have the following defects: 1. The use method is single, and the existing handwriting devices generally can only be matched with computer terminal equipment (ie: PC), and cannot be compatible with smart phones, tablet computers, etc. Portable mobile devices, which greatly limit its application scenarios and scope of application; 2. The practical function is single. After the existing handwriting equipment is connected with the computer terminal equipment, it can only be used as a signal acquisition device for handwriting traces. It is also necessary for the operator to watch the computer screen in real time to confirm the handwriting trajectory. In this way, since the operator's hand movements and eye movements are respectively scattered on the computer terminal device and the handwriting device itself, the difficulty of writing, drawing and other operations is increased. ; 3. Poor portability and mobility. Most of the existing handwriting devices can only be used in fixed places with computer terminal equipment, which is not convenient for operators to write, draw and other work anytime and anywhere; 4. The performance is unstable. Electromagnetic interference is prone to occur in the environment, which will lead to problems such as unsmooth writing, slow recognition speed, and poor user experience.
