| Outline of Final Research Achievements |
This research investigated whether pseudo-haptics is elicited in spatial augmented reality (AR) environment. In particular, it focused on the shape and softness sensations. Projection systems were built, in which psychophysical experiments were conducted for the investigation. As a result, it was confirmed that pseudo-haptics was elicited by projected imagery onto user bodies and touched objects. Especially for the softness perception, a computational model was developed, which estimates perceived softness when the visual effects are projected. It was confirmed that this model could work with an accuracy of less than the just-noticeable difference of human softness perception.
