Multifunctional interaction type intelligent multimedia electronic blackboard technology

Abstract

The invention relates to a multifunctional interaction type intelligent multimedia electronic blackboard technology. A blackboard is designed as a large-format touch screen system. A built-in computer judges writing and drawing tracks according to change of pressure and electric characteristics of the blackboard and the stressed signals of electronic chalk, and the displayed result in the contact position is erased by judging the change of the pressure and electric characteristics of the blackboard and the stressed signals of an electronic blackboard eraser, so that the writing-on-blackboard function is realized. Through a peripheral equipment interface, multimedia information of a peripheral computer can be displayed in any position of the blackboard. A built-in drawing-assisting program can assist a teacher in manually drawing regular geometric figures. At the same time, the writing content on the blackboard and teaching recorded sound of the teacher are simultaneously and dynamically stored in a storage system, and a student can learn the stored multimedia writing-on-blackboard teaching videos at any time. While inheriting the advantages of the writing-on-blackboard teaching and current multimedia teaching, the multifunctional interaction type intelligent multimedia electronic blackboard technology reasonably avoids the defects, and therefore the functions of the blackboard are greatly improved and enriched.

Description

technical field [0001] The invention relates to a multifunctional interactive intelligent multimedia electronic blackboard technology, which utilizes a modern touch screen electronic system and designs other auxiliary mechanical and electronic equipment to improve traditional education and academic communication tools, and belongs to the field of education and academic communication. Background technique [0002] The current education and academic exchanges mainly use multimedia teaching and blackboard teaching at the same time, and the current domestic teaching trend has a tendency to despise teachers' blackboard teaching and purely use multimedia teaching. This teaching method is recognized in the teaching of mathematics and science. Has some major flaws. [0003] The main defects of multimedia teaching, especially pure PPT teaching are as follows: [0004] 1. The size of the slide area is too small compared with the blackboard, so the knowledge points that can be accommo...

AI Technical Summary

Problems solved by technology

In this way, students or listeners form a visual gap in the content of the previous slide, causing difficulties in understanding and remembering

[0005] 2. The switching of slides caused students to be unable to connect in time with the previous parts

[0006]Third, the evolution process of mathematical formulas on the slides is often relatively fast, resulting in visual impact and thinking tension for students, but in traditional blackboard teaching, The teacher takes chalk on the blackboard, evolutionary formulas and theories, and the students' own calculations on the manuscript paper are two identical processes, so there is a buffer time for visual memory

So students have to look at the previous things again, but they can't be realized.

[0009]Second, it is very difficult for teachers to draw on the blackboard and the graphics formed by manual drawing are irregular, but it is impossible to display the dynamic changes of graphics or objects on the blackboard , have to use various arrows to represent the dynamic effect, which is very inconvenient, and it is difficult for students to form an intuitive impression

[0010] 3. Students have to take a lot of notes when they want to go back to read the content written on the blackboard by the teacher after class, which causes distraction

[0011] 4. Students in the back row of the classroom may not be able to see some details of the blackboard writing

[0012] V. Some students are sick or leave school to go home, and it is inconvenient to attend class, so they have to use the notes of their classmates to read

However, products using touch screen technology in education and academic communication have not yet been developed, and no related inventions have been seen so far.
