Outline of Final Research Achievements

To evaluate objectively the influence of visual attraction of wood and wooden interior walls on the changes in psychological and physiological states of human observers, we carried out some experiments which made subjects observe wooden walls implemented in the laboratory or wood grain patterns generated by the computer graphic technique. We measured subject's responses which were brain waves, autonomic nerve responses related to the blood circulation regulation, and visual impression evoked by the stimuli. Our results revealed that decorative concaves on the surface of wood elements, amounts of wood occupied in a wall, directions of wood elements were not only the relatively simple design factors but they evoke the psychological and physiological changes of observers. And we also emphasized that the visual characteristics of wood extracted by using the image analyses were able to explain the psychological impressions of observers.
