The greatest obstacle in developing distance learning system is the lack of real-time interaction. This paper provides a real-time interactive shared system for distance learning that combines the audio, video and seminar. The remote learners can study and exchange opinions with the instructor through this system in real time. After the test between Waseda University and Guilin University, we find that the system can well simulate traditional classroom and improve interaction among participators, which not only saves learners’ study time and improves their learning interests and efficiency, but also improves the teaching freedom of instructor for e-whiteboard is introduced.
