Description

Electronic whiteboard system, input device, processing device and processing method

technical field

The invention relates to the field of electronic equipment, in particular to an electronic whiteboard system, an input device, a host device and a processing method.

Background technique

Electronic whiteboard system (referred to as electronic whiteboard) is an electronic device widely used in various fields, such as: education and teaching, video conferencing, multi-person discussion and other scenarios. This equipment is a high-tech product that integrates various technical means such as electronics, software, and communication. Specifically, it can be realized by applying the principle of electromagnetic induction, combining computers and projectors, and then achieving the purpose of paperless office and paperless teaching. With the wide use of electronic whiteboards in various fields, the functional classification of electronic whiteboards has also been further refined. Different scenarios have put forward different personalized requirements, such as: copy electronic whiteboards, interactive electronic whiteboards, etc. . Among them, interactive electronic whiteboards generally provide drawing functions, that is, handwriting input, such as marking, instant creation, and text input. However, when multiple people use it collaboratively and draw on the electronic whiteboard, none of the current electronic whiteboard products can identify which user has specifically entered what content. In various usage scenarios such as meetings and discussions, there are often situations where multiple people draw on the electronic whiteboard at the same time. If it is possible to distinguish the input authors of different content at the same time and complete functions such as automatic meeting minutes sorting according to roles, it will greatly improve work efficiency, reduce human processing errors, and improve the traceability of the communication process. In view of the above problems, the existing technology often adopts the method of manually recording and sorting out the corresponding information, such as: setting up a special meeting minutes person or a discussion person who also serves as a meeting minutes person to manually record the information in the meeting process, etc. The disadvantages of this method are: (1) the cost of special meeting minutes is increased, such as the secretary, who may not understand some details; To the effect of the meeting; and no matter which method is used, the uncertainty of human participation may lead to the introduction of errors, which reduces the traceability. Another processing method is to directly output the content recorded by the electronic whiteboard, that is, the electronic whiteboard has the function of printing out or directly saving to the host, and the discussed content can be output and saved in the form of paper or data. But the disadvantage of this processing method is: the content recorded by the traditional electronic whiteboard does not have the role (author) information, that is, it is impossible to make a one-to-one correspondence with who specifically entered what content in the meeting or discussion, and often can only be used as meeting minutes.
