One is a remote control system with haptic media and video. In the system, we can write characters by controlling a haptic interface device at a remote place with another haptic interface device while watching video. The other is a remote instruction system with haptic media, video and voice. By using the system, a teacher can actively write characters and teach a student how to write the characters. The student can also write characters actively, and the teacher can confirm how the student writes the characters. We investigate the influences of network delay on QoE for the two systems with the two haptic control schemes.展开更多

This paper presents the resource based learning aerobics teaching design network course should adapt to the application mode of network teaching and traditional classroom combination; that will provide teaching demonstration, teaching contents for students as well as the function of self testing evaluation and provide the job management, teacher online Q ＆ A, database and knowledge base construction, greatly improving the ＂aerobics＂ teaching efficiency.展开更多
