A novel method to make digital content using teacher tracking system

In this paper, we propose a novel method to make digital content by using teacher tracking system (called TTS). In order to make a digital content which includes the activity of the teacher and the writing on blackboard, we use two cameras to solve the problem. The first one is employed to track the teacher and record the activity of the teacher (TTS), the other one is used to implement the system of acquisition of writing on blackboard. Our method can make these two systems work automatically by some simply initialization. We build the digital content by composing the video of the activity of teacher and the image sequence of the writing on blackboard. Therefore, the student can review the whole lesson to enhance understanding and deepen the impression of the knowledge and key points. Our digital content can be also published in the internet, so the students can study in anywhere and anytime.
