There are some Environmental Control Systems (ECS) for severely disabled persons. It is useful for them to enhance the quality of life by using ECSs. On the other hand, since these equipments are expensive because of complex works for setting them up, it is impossible for disabled persons to use them widely. In this research, we develop the systematizing support system which can be combined and built according to a life of a disabled person. We aim at offering an inexpensive support apparatus which has a necessary minimum function. We make a field test about our ESC in a severely disabled person's home, so we have a good result for the disabled.
