| Outline of Final Research Achievements |
In this research, we proposed a visuo-haptic system that can provide users with the sensation of touching various virtual shapes, by realizing the Pseudo-Haptics that can adapt to a touching with multi-fingers. The previous way, which modifies the movement of virtual hand to alter a shape perception, evokes a spatial inconsistency when it's used for a touching with multi-fingers. To solve this problem, our research constructs a real-time video processing method that can compose visual stimuli with spatial consistency in that situation, by modifying a hand image's posture naturally with an image deformation algorithm. Through user experiments, we revealed that this method can modify the perception of shape and stiffness when users handle an object with multi fingers. Furthermore, we applied these findings to a modeling system and a haptic display on the mobile device, and confirmed these effect through exhibitions.
