Wearable devices have been numerously reported so far which aim to augment eating experience by applying crossmodal perception that multiple senses are interacting with each other and are integrated as one experience. As for devices which append sensory stimuli artificially, it is considered that multisensory integration would be lost if a delay between multiple sensory stimuli arises. On the other hand, a novel experience could be also obtained by utilizing the delay. This research investigated the perception of a time-lag between delayed auditory feedback of chewing potatochips and actual chewing behavior. As a result, most of the participants perceived time-lags at more than 200 [ms], and this result can be attributed to the durations of closing and occlusal phase of mastication. This research also investigated the effect of the time-lag on “zakuzaku” (crunchy) feeling of potatochips. As a result, 100 [ms] time-lag augments zakuzaku feeling most, and the evaluation values of zakuzaku feeling tend to vary more widely when the time-lag becomes perceived. According to the above results, this paper showed that delayed auditory feedback of mastication could augment zakuzaku feeling without spoiling multisensory integration.

近年VRの技術に注目が集まる中で、クロスモーダル現象(五感が相互に作用しあうことによって起こる現象)による錯覚が重要視されている。クロスモーダル現象に関する研究は視覚に関するものが多いが、聴覚に関しても着目することでVRの臨場感の向上やメタリアリティの発展につながるのではと考え今回の研究に取り組んだ。具体的には弾力性のある仮想物体に対するインタラクションに対して感覚を得られるか調べた。
