This paper introduces a 3D free-viewpoint video-browsing interface that applies multi-touch manipulation to virtual camera control. It is difficult for general users to browse 3D free-viewpoint video because they are not accustomed to controlling a virtual camera from a free-viewpoint perspective. We focus on the multi-touch interface installed in tablet PCs as an input device, which has become a popular interface thanks to its easy and intuitive manipulation. We conduct subjective evaluations to define suitable gestures for virtual camera control. The results reveal which multi-touch gestures users tend to prefer for controlling a virtual camera.
