Measurement in Social Life

The extraction of event that cannot be detected with conventional equipment can be considered to be a precise measurement in the wide sense. In this paper, the measurement in social life is introduced. It is divided into three fields (global environment, living conditions, and life support and welfare). In each field, the method is introduced. Especially, an intelligent sensing technology is important. It is not only a measurement system for extraction of physical value, but also a system that acquires the information which human perceives and requires. The information is obtained by processing a physical value, judging, and recognizing. It is also important to examine the correlation of a physical value and a psychological value for the extraction of the information. Some examples on the study are shown. A comfortable and safe life is expected to be achieved because the measurement technology in social life advances further.
