This article describes a new automatic digital content generation system we have developed. Recently some universities, including Hosei University, have been offering students opportunities to take distance interactive classes over the Internet from overseas. When such distance lectures are delivered in English to Japanese students, there is a pressing need to provide materials for review after class, such as video content on a CDROM or on a Web site. To meet this need, we have developed a new automatic content generation system, which enables the complete archiving of lectures including video/audio content, synchronized presentation materials, and handwritten traces on virtual whiteboards. The content is generated in real time and is immediately available at the end of the class. In addition, this system incorporates a unique video search algorithm which adopts a phonetic-based search technology. This enables quick review of the video content by typed-in keywords. The system can automatically create a vast amount of digital content and provide students with an efficient learning tool.
Real-Time Distance Lecture System
Since April 2002, Hosei University has been offering a pre-MBA course toward an MBA to be acquired by further studying abroad for a minimum of one year. Figure 1 shows photos of the pre-MBA class. In this course, a service is provided in which students can attend some MBA-accredited courses in advance at Kudan Hall in Ichigaya Campus through distance classes from the Hosei University Research Institute California. Furthermore, an international distance class on welfare engineering given by lecturers in the US, Korea, and Hosei University in Japan is being offered as an interdisciplinary as well as a crossover subject to Ichigaya, Tama, and Koganei Campuses from April 2003. Figure 2 shows a set of scenes of the classroom.
