An intensive 3D-simulation method for designing living environment assisting human behaviors has been developed. Basic motions necessary for daily life such as "arm-reaching, stand-up and sit-down, go up/down the stairs, etc" may be one of the most important factors for efficient design scheme. In this study, a rich human-body model with 44-DOF has been utilized in formulating basic daily-motion modules of human. Using multi-agent simulation technique with those modules, suitable living as well as housing environments can be designed with less efforts comparing to the mock-up type designing method widely used in industry.
