Outline of Final Research Achievements

This study aimed at controlling a living space with variety applying comfortability driven by parasympathetic nervous system and vitality driven by sympathetic nervous system.
The study was started by constructing a real living-space based experimental facility with an ability to change the size of room size for giving different feeling to the participants. The next step was measuring biological indices in autonomic nervous system during two stages (relaxing and vital stages) using a real living-space based experimental facility. The outcome of this study was to show new evaluation approach for the status of human vitality using indices for autonomic nervous system. Especially Lorentz-plots and frequency analysis with regard to heart-rate variability were compared in the experiment and its availability was advocated.
