To realize the ideal of “ageing in place,” one has to remodel the current house to fit the needs for the ageing process of the elderly. Based on the “prevention” concept and the four phases of ageing: old, elderly, aged, and very old, this integrates human factors, green sustainability, somatosensory gaming, and gerontechnology to develop a graceful living environment as a foundation of the “ageing in place.” Subproject 1 will study how to modify current house, without changing the structure, to have a graceful living space. Subproject 2 will design appropriate games to fit different stages of ageing in order to reduce the sense of deterioration with age. Subproject 3 will develop an intelligent living environment from social, psychological and physiological perspectives. The subprojects will be integrated and will be demonstrated through a computer animation model. The results of the project will provide a graceful living environment with the ingredients of sustainable living, intelligent somatosensory, delightful ageing. In subproject 1, in order to face the ageing society, the living environment must be designed to fulfill and accommodate the changing status of an old person. The basic idea of this proposed research is how to modify the house where an old person is current living to minimize the inconvenience and achieve the gracefulness of the residence, and to realize the “ageing in place” concept. The research methods used in this research are human factors principles, charming quality criteria, and general design principles. The research will study the modification of a “bathroom” to be hygienic and healthy, the “kitchen” to provide comfortable functions, and the “bedroom” to provide a peaceful and private resting space. Other three subprojects will provide inputs to the design guidelines, and the results will be presented as a computer animation model.
