An expanded range of expression will be possible in cyberspace and the real world if we can perform scent presentation that matched the use purpose. Numerous studies investigating the effects of fragrances have been conducted using physiological information. However, conflicting results regarding the relation between scents and emotions have been obtained, and no consensus has been reached. In addition, previous studies investigating the influence of scents on feelings have considered only the types of scents. Therefore, we focus in this paper on the strength of fragrance and propose a scent presentation technique that varies the strength of scents with time. We change the strength of the scent based on three patterns: pink noise, random and constant. We estimate the feelings of subjects by analyzing brain waves and heart rate. We experimentally confirm that scent with a constant strength is the most effective of the three scent presentation patterns for increasing relaxation, and that the relaxation effect of pink noise cannot be applied to fragrance.
