Comfortable space management based on biometrical information

It is difficult to define a comfortable space for people. It is partly because comfortableness relates to many attributes specifies a space, partly because all people have different preference, and also because even the same person changes his/her preference according the state of their health, body conditions, working state and so on. Various parameters and attributes should be controlled in order to realize such a comfortable space according the database of past usages. Information obtained form human bodies such as temperature, blood press, alpha wave and etc. can be employed to adjust the space to the best condition. The objective of the paper is to present the possibility that a space can be adjustable to human condition based on human brainwaves
