A multimodal teaching system based on Internet-of-things

Abstract

A multimodal teaching system based on Internet-of-things, wherein a host computer with a nanometer display screen is used as teaching display equipment. The front and upper end of the nanometer display screen is provided with an intelligent camera. A holographic projection imaging system is built in the host compute. And the following application software, a face analysis unit, a display screen control unit, a teaching unit, a large data unit and a holographic projection imaging unit are installed in the host compute, and the host computer is located at the lecture platform of the classroom. The holographic projection imaging system comprises a face analysis unit, a display screen control unit, a teaching unit, a large data unit and a holographic projection imaging unit. Black is no long required for that invention, Whiteboard for teaching, Teachers or students can use the touch screen to find out all kinds of teaching information they need, through the intelligent camera to the student 's face recognition attendance, lighten the teacher 's daily work of attendance, Also can intelligently analyze the students' learning situation, learning attitude, get the students to the teacher'seducation level recognition, through the big data analysis platform, can facilitate schools and parents to understand the teaching situation, but also has the video teaching image stereo projection to the platform, so as to give students and teachers face-to-face effect.

Description

technical field [0001] The invention relates to the technical field of multimedia teaching, in particular to a multi-modal teaching system based on the Internet of Things. Background technique [0002] Multimedia teaching means that in the teaching process, according to the teaching objectives and the characteristics of the teaching objects, through teaching design, rationally select and use modern teaching media, and organically combine with traditional teaching methods, participate in the whole teaching process together, use various media information For students, a reasonable teaching process structure is formed to achieve the optimal teaching effect. Compared with traditional teaching, multimedia teaching has better teaching effect, not only brings convenience to teachers' teaching, but also allows students to effectively receive more knowledge points, so it is more and more widely used. [0003] In the traditional multimedia teaching mode, computers and multimedia disp...

Problems solved by technology

In actual teaching, in order to achieve a good teaching purpose, it is necessary to combine the use of traditional teaching aids blackboard and whiteboard, which will cause a variety of equipment to occupy the limited space of the classroom, and will also lead to investment in education funds

For the needs of teaching, the teacher usually needs to carry a USB flash drive to store the teaching content in class. Not only is it inconvenient to use, but the storage content of the USB flash drive is limited, which is not conducive to the teaching process.

Traditional multimedia teaching relies on manual statistics to obtain data for the statistical analysis of teachers' teaching level and students' learning situation, as well as students' feedback on teachers' education level. Not only is the actual operation process cumbersome, but also various data are not time-sensitive.

In the existing teaching mode, the attendance in class is generally operated by the teacher, which not only wastes time, but also brings unnecessary trouble to the teacher

In the traditional multimedia teaching mode, the teaching content displayed by multimedia equipment can only be two-dimensional. For example, the teaching content of the world teacher shown in the video can only be displayed on the flat screen. The effect of lectures, so there are certain limitations
