It is difficult to define a comfortable space for people. It is partly because comfortness relates to many attributes specify a space, partly because all people have different preferences, and also because even the same person changes his/her preference according the state of their health, body conditions, working states and so on. Various parameters and attributes should be controlled to realize such a comfortable space according the data-base of past usages. Information obtained from human bodies such as temperature, blood pressure, α brainwave, heart beats and etc. can be employed to adjust the space to the best condition. In order to realize a comfortable space, first we recognize human states and behabiors, and second we provide an apporpriate environment for a focal person according to his/her state. The objective of this paper isto achieve a comfortable space in terms of affectie behaviors or actions. We deal with such techneaques as KANSEI engineering. In other words, it is required to realize our comfortable environment suitable to feelings. Kansei Engineering is one to offer better products to the customers by employing human sensitivity.
