Tsuda et al. reported chaotic behavior of human finger photoplethysmograms (FPPs) and proposed the possibility of shape of the FPP attractor an indicator of mental and physical condition of subjects. To perform a quantitative evaluation, a quantity characterizing the of attractor shape was extracted. Furthermore, to measure the process of changing attractor shapes due to health promotion methods, a successive measuring system of attractors was developed. Basic results for quantitative evaluation obtained with this system were described.
