| Research Abstract |
High-Definition (BD) video has wide view and high resolution, and it can suitably used in distance education. With HD video even without camera work, remote students can study as live students. The Center for Research and Development of Educational Technology, Tokyo Institute of Technology transmits many lectures to domestic high schools and foreign universities. Actual distance lectures shot by expert cameramen using Standard-Definition (SD) video are also taken by HD video without any camera work. Those videos are viewed by subjects and we conducted questionnaire survey and eye tracking.
The main results are;
1. Expert cameramen properly shoot areas where students mainly see, but we demonstrated quantitatively that students tend to see outside of those areas. So it is practically impossible to satisfy all the students.
2. Teaching Assistants cannot control a camera, but even without any camera work HD video can show wide area with enough resolution. So it can suitably used as distance education media.
These results show that proper educational environment can be set up by preparing wide band network to transmit HD video with reduced labor cost for expert cameramen. In those cases, however, big screen should be prepared not to make characters on the board too small.
