Teaching system based on smart classroom and working method thereof

Abstract

The invention relates to a teaching system based on a smart classroom and a working method thereof. The system comprises a smart blackboard, a written content acquiring device, a processing device anda display device. The smart blackboard has a writing and touch detecting function. The written content acquiring device is used to acquire the written content on the smart blackboard, and send the acquired written content to the processing device for saving and processing. The processing device determines whether a preset information identifier is written on the smart blackboard according to a touch point position detected by the smart blackboard. If the preset information identifier is written on the smart blackboard, the content labelled by the preset information identifier is identified inthe written content acquired by the written content acquiring device, and relevant information is retrieved and displayed on the display device according to the labelled content. According to the invention, a touch device is added on the blackboard; the written handwriting information is acquired; the relevant content is retrieved and displayed in the interactive smart tablet device; and the content displayed by a display unit is well integrated with the content written on an ordinary glass blackboard.

Description

technical field [0001] The invention relates to an application technology of a smart classroom, in particular to a teaching system based on a smart classroom and a working method thereof. Background technique [0002] The nano-touch blackboard is an intelligent interactive teaching device capable of touch interaction, multimedia teaching and chalk writing. With the help of nano-touch technology, the traditional handwriting blackboard and multimedia equipment are combined to easily switch between chalk writing and multimedia applications. , the same area on the blackboard can be written with chalk like an ordinary blackboard, or can be touched like a touch display device to watch various rich multimedia applications such as PPT, video, pictures, animations, etc., so it can be widely used in multimedia teaching Environment. [0003] Chinese patent application CN201410464448.9 discloses a touchable display blackboard, including a glass blackboard, a touch film and a display un...

AI Technical Summary

Problems solved by technology

[0004] None of the above-mentioned smart blackboards can realize the correlation between the writing content and the display content. For example, the content of the electronic courseware made by the teacher before class displayed on the display unit cannot be compared with the relevant content in the electronic courseware written on the ordinary glass blackboard during class. As a result, the content displayed on the display unit cannot be well integrated with the content written on the blackboard on the ordinary glass blackboard

Moreover, the glass blackboard area corresponding to the display unit and the touch film cannot achieve both touch operation and ordinary blackboard writing functions, that is, when the glass blackboard area realizes the writing function of an ordinary blackboard, the touch function cannot be realized. When the blackboard area realizes the touch function, it cannot be used as an ordinary blackboard for writing, or even if content is written on the glass blackboard area, the content will overlap with the content displayed on the display unit and cannot be clearly identified
