One form of adding interactivity to online learning is video annotation, which is an active field of research in content-based video retrieval and summarization. However, it is less known in educational contexts, partly due to the lack of video annotation capabilities in current learning tools and systems. With the popularity of Web video lectures, there is a rising demand for the support of discussion and collaboration around video contents. This work presents the design and preliminary evaluation results of a Web-based multi-user video annotation environment. The system allows users to attach notes to video segments and share their notes with other users asynchronously. Unlike the traditional use of video annotation, which is mainly designed as a single-user desktop application, the Web-based implementation allows users to learn and collaborate with fewer constraints of time and location. At the same time it can be readily integrated in a Web learning environment.
