Browsing and Retrieval Tool of Slides and Related Lecture Movies

In this paper, a browsing and retrieval tool of slides and related lecture movies is proposed. This tool is developed as an Android application, and browsing of slides can be executed in offline environments. If high-speed network is available, users can browse related lecture movies. This tool has retrieval functions such as keyword retrieval and visual retrieval. In visual retrieval, users can retrieve slides without inputting keywords. This means that the proposed tool is suitable for smart phones, because the retrieval of slides can be realized only by touching smart phone displays.
