In order to realize touch communication with virtual characters, we propose a new tactile presentation method which uses the user’s own body part for a sense of touch along with a sense that the body part is possessed by virtual character. In this paper, as an initial study, we created a system in which the user and a virtual character’s hands are visually fused, and a pseudo-high-five is performed. The applicability of the proposed method and points for improvement are discussed based on the results of user experiments.

In this study, we attempt to enhance emotion in online live music concerts by focusing on the influence of entrainment to the rhythm of music on emotion. We propose a light stick-type device that changes the audience's own light stick swinging motion and their perception of it by adding a force stimulus to the audience's light stick swinging motion. Experimental results suggest that the proposed device promoted the user's light stick swinging behavior and enhanced emotion. Results also suggested that presenting force stimuli in accordance with musical rhythms could be a useful for presenting the presence of other people.

Recent progress of high-speed projectors using DMD (Digital Micromirror Device) has enabled low-latency motion adaptability of displayed images, which is a key challenge in achieving projection-based dynamic interaction systems. This paper presents evaluation of different approaches in achieving fast motion adaptability with DMD projectors through a subjective image evaluation experiment and a discrimination experiment. The results suggest that the approach proposed by the authors, which updates the image position for every binary frame instead of for every video frame, applied to 60-fps video input offers perceptual image quality comparable with the quality offered by 500-fps projection.
