Although there are various lecture recording systems, they still have many problems. For instance, the type of lecture material which can be recorded is limited to PowerPoint Slides and recording process needs subsequent editing work. We developed a system which overcomes such limitation. The features of this system are threefold: 1) installation of software into instructor’s PC is unnecessary, 2) subsequent editing work is also unnecessary, and 3) high definition recording is possible. The system we developed allows creation of precise digital learning content.
We used our system for four years in actual university lectures. As a result of comparative analysis on its educational effect, the validity of the system can be proven. Two companies developed the products using the result of this research.
