| Outline of Final Research Achievements |
Mixed reality (MR) is the technology which merges real and virtual worlds in real-time. In MR space, a real object can be changed its visual appearance by superimposing a CG image (CGI) on it. In this research, we have studied "Shape-COG Illusion" and "Dent-Softness Illusion" which we discoverd. These illusions are developed by psychophysical influence on sense of center-of-gravity (COG) or hardness of a real object which is superimposed by a computer generated image (CGI). In this study, we confirmed the conditions, absolute thresholds, and difference threshold which create these illusions.
