Efforts to support the skills of developmental child training/education workers are implemented using visual information captured by nursery teachers, therapists, and children's intervention work. This paper proposes a highly operable multi-view video browsing interface utilizing a multi-touch input method, which is suitable for users who are unfamiliar with handling devices that require complicated operations. We conduct evolutional questionnaires and request surveys at an actual developmental child training site and propose an interface based on the results. The proposed interface improves the operability and visibility by two approaches. First, we differentiate between the operation methods to reduce the operation errors that occur during image browsing. Second, we introduce image processing to promote the understanding of the presented image. In experimental evaluations, we investigate the video presentation of scenes that users can easily understand and verify the operability improvement of the proposed interface by a comparative experiment using our pilot system.
