Interactive Learning Platform Of Electronic Whiteboard Based On The Network

Along with the development of computer technology and communication technology, the computer network emerged and has made a great progress. The computer network brought earth-shaking changes to the lives of people; the advantages of computer network have influenced the various walks of life deeply. Education faces the problem: teaching mode must be innovated in all aspects to adjust to the current situation. The original instruction which only meet real-time teaching classroom is not the mainstream now. The education has changed from the closed to the open, and we have seen the new education way of teaching in the range of the time and the space. Open education, lifelong education and EFA have become the mainstream of modern education. Online learning is becoming a beneficial supplement of learning; the advantage of learning network has appeared, it can meet many special needs. However, Network real-time interactive learning and emotional factors are often restrained by some objective factors. Especially, it's interaction could not be matched with class teaching, because it's not only restricted by the network speed but also the various operation platform. The new emerged electronic white board supplies the platform for all to share the ideas; we can realize the real-time interaction and online discussion through it. in addition, the video and audio synchronous transmission technology in electronic white board also help everyone communicate with each other on-line. Interactive electronic board itself is a complete system and a learning platform. It can be loaded with database of resources, and it supports various audio, video formats and operating software. Electronic board is like a piece of blank paper, which allows operators to enter, change, and erase related content. At present, the interactive electronic white board has been widely used in education, military, economic and medicine, etc. Using interactive electronic board can not only perform online video editing, meetings and online discussions, it also can undertake remote control and online services, etc. With more and more powerful function of electronic board, the human demand is higher and higher, and the scope it applies to will be wider.The paper mainly carrys out the following works:(1) Researching various interactive electronic board input mode and the principle of its input in detail and puts forward the subtle ways.(2) The latest audio and video research data formats and compression method to study how to guarantee in the network transmission before maximum not compress and distortion in the process of realizing large flow uninterrupted transmission guarantee the quality of online interaction.(3) Study online detection technology, remote sensing technology and on-line control integrate network real-time interactive improvements have good embodiment.(4) Study design interactive electronic board interface, easy operation interface and comprehensive functions, facilitate the good operator.This paper intends to introduce information input way and the latest algorithm of the electronic white board in details, explain it's inner identify theory. In addition, it also puts the video, audio and data transmission technology into details, improve in some degree, do some research in online detection technology processing and interactive long-distance on-line control, etc. The aim is to perfect the function of interactive white board, and it play a bigger role in the network education.
