    In recent years, many researches on cross-modal sensory correspondence between smell and the other senses have been conducted. We focused on the relation between the sense of smell and that of motion. Vection, which is a visually induced illusion of self-motion, was used as a sense of motion, and effects of vection on scents were investigated. We measured the discrimination threshold of scents using a pair-wise comparison of two scent pulses under the condition of vection stimuli and two kinds of scents, and found that there were some conditions with significance difference. This result indicates that the sensitivity of smell may be affected by vection.

    Projection mapping to the dining table has been introduced in multiple restaurants. Does this kind of change in eating environment with projection mapping work only for entertainment? In this study, we examined whether changes in eating environment with projection mapping actually change the thermal/olfactory/taste perception and palatability of food. Tempura was chosen as a food, which has distinctive texture, aroma and taste, and has a strong tie with a specific eating environment in Japan, and a projection mapping system was constructed to project images and sounds to simulate a counter in a tempura restaurant around tempura. Through two experiments using this system, we suggested that the aroma, temperature, taste strength and palatability of the tempura improved by the effect of the projection mapping. We also suggested that the linguistic information related to tempura also enhances these perception, but the effect is weaker than the one of change in eating environment with projection mapping. These results suggested that change in eating environment with projection mapping helps to perceive the sensory information expected to be obtained in the environment.

    When realizing projection-based augmented reality with a fixed projector, projectable range is limited. We make a drone fly around user and project onto a planar target object, and move the projector to the position where the luminance of the projected image is as high as possible without hitting user. Moreover, the projected image is geometrically corrected depending on the projector's position. We built the prototype system to evaluate its performance.
