ABSTRACT
New technologies became widespread at the same time as the rapid economic growth that started in Japan in the mid-1970s, making our lifestyles very convenient and comfortable. Technological advances in manufacturing and information sciences have made it possible to create customized products and environments in response to various human needs. However, these new technologies or products often failed to provide true satisfaction for their users. More and more people are now experiencing technologyrelated stress and fatigue, and the number of illnesses caused by these problems is increasing.
