In this study, a subjective experiment was conducted using both a virtual environment technology and an electrodermal activity measurement method. This study is a part of research aimed at obtaining knowledge about window width that does not cause mental strain. The study results revealed that 1) These results mainly indicate that the narrower the window width, the higher the mental strain on the person staying in a room. 2) The results also suggested that mental strain varied depending on the type of avatar. These findings might be valuable when creating a window arrangement that results in less mental strain.
