Abstract
This paper describes a study of human-interface techniques for video programs using multiple camera angles which has been developed at the National Institute of Multimedia Education (NIME) for teacher education video programs. The videos are taken by more than one camera in a classroom in genenal. To develop a video program, the movie director has to edit video tapes choosing camera angles; however, it is not necessary to edit video tapes in this way. since it is possible to record and simultaneously view all camera angles using DVD-Video, With the use of DVD-Video, NIME has been developing instructional materials for teacher education. In this study, the author developed human interface techniques for multiple camera angles and analyzed the operation logs. Based on these results, the author proposed several video techniques for multiple camera angles.
