With the population of the elderly and disabled growing, day care services became one of the mainstream community care. This study takes A, B in Yunlin and C in Changhua County of day care centre as cases for the elderly and workers, discussed on the impact and meaning of actors in day care center . Studies have found that the importance of space hardware configuration in accordance with regulatory requirements was greater than the needs of the elderly and the staff. Because house construction of day care centres cannot be changed, the staff increased nursing loads to take care of disability or dementia, but the staff was more negative that the owner or master who has power of adjusting space. If disability or dementia of the elderly lost in the route, they often wanted staff to help let them less to move. The staff thought space equipment to facilitate its work as a priority, the use of space power is higher than that of the elderly. From the perspective of actors (disability or dementia elderly and staff), we should find the optimum balance in the space requirements of day care centre.
