| Outline of Final Research Achievements |
This research discusses a method of supporting blackboard based lectures. In this method,students watch the video of the blackboard based lecture on a tablet computer. Some parts of the blackboards are recorded by two or more cameras, and a player is designed to enable the user to view and listen to any portion of the lecture. The videos in our method must be high resolution and high quality for students to be able to identify the characters on the board. However, when many students receive the video by wireless LAN, the bandwidth available for each student decreases. We maintain the image quality of the video by decreasing the frame rate. Students completed questionnaires to evaluate these videos.
