<P>PROBLEM TO BE SOLVED: To provide a behavior analysis system that can prevent an accident and can analyze a factor in an accident, in a behavior analysis system for analyzing behavior of a subject such as a doctor, a nurse or a factory worker. <P>SOLUTION: The behavior analysis system 10 includes a computer 12, to which data on the number of steps and the lean angle (angle of upper body lean) of a nurse measured by a measuring device 30 are transmitted. From the measured number of steps and lean angle, behavioral feature vectors of the nurse are created, and from behavioral feature vectors including accidents, for example, dictionary data on particular accidents are created. After the dictionary data creation, the creation of behavioral feature data on the nurse at a certain time point (current time point) and their comparison with the dictionary data determines whether an accident may possibly occur or not. If there is a possibility of an accident, an alarm is raised to avoid it. The prediction and avoidance of accident occurrence can prevent an accident. <P>COPYRIGHT: (C)2004,JPO |
