非正面視点からの自己像を利用した対話インタフェースにおける指示容易性評価

抄録

The pointing operation in video communication with a "shared space" approach is evaluated. The shared space is a constructed image in which remote image is overlaid with self-image. It is known that such way of communication can promote natural conversation including easy gaze recognition, feeling of space sharing, and so on. However performance of pointing operation in the shared space has not been examined fully. Experiments have been done to evaluate it with various parameters such as viewing angle, mirroring of the shared space image, and so on. As the results of experiments, guidelines for the shared space design using pointing are described.
