Fragrance influences the psychophysiological state of a person as the volume of fingertip plethysmogram changes during one’s aspiration of aroma. Recent studies have used aroma in various settings, such as for medical care, relaxation, and productivity-enhancing environments. However, no study has elucidated the kind of behavior shown on the fingertip plethysmograph near the stimulation and discrimination threshold for the sense of smell when the odor intensity of aroma changes. Although our research suggests that emotions can be evaluated using the Lyapunov exponent of chaos analysis, no study has clarified the appropriate method for chaos analysis. Therefore, in this study, we performed a chaotic analysis of fingertip plethysmograms for evaluating emotional changes near the stimulation and discrimination thresholds during aroma inhalation. Results were evaluated using a correlation dimension and Lyapunov exponent. The optimal analysis method was examined thereafter.
