I7-2　Effect of Odor Stimulation According to E-Book Reading

Abstract

This study aimed to find out whether the reading fatigue by an e-book can be relieved through the stimulation of Lavender odor which has a relaxing effect. The experiment was conducted the subjects of 15 men and women in their twenties who had no olfactory disorders, Photoplethysmography(PPG) was measured for the fatigue, and the subjective assessment was conducted for the subjective fatigue. As the result of the experiment, the fatigue was lower when e-books were read in the condition where Lavender odor was presented than when only e-books on a smart phone were read, where there was a significant difference(p<0.1). Therefore, as the result of the experiment in this study, given the effect of Lavender odor, the structure of a brain, and the cerebral acting region of sight and smell of the previous studies comprehensively, it is supposed that the increase in visual fatigue due to e-book reading outpaces the relaxing effect of Lavender odor which is absorbed through smell. It is judged that there should be many studies on the interaction on the cerebral capacity of sight and smell in the future.
