Abstract:
1. A behavior monitoring system comprising: a plurality of member terminals held respectively by a plurality of members conducting a group activity and configured to collect and store behavior information of the members to match time information, the behavior information including location information, orientation information, view information, and motion information; at least one leader terminal held by a leader and configured to receive and store the behavior information of the members collected by the plurality of member terminals; and an analysis terminal configured to receive the behavior information from the at least one leader terminal and the plurality of member terminals, to estimate behavior distributions corresponding, respectively, to the location information, the orientation information, the view information, and the motion information included in the received behavior information, and to extract a feature behavior through analysis of a behavior information difference between the plurality of members for the estimated behavior distributions respectively, wherein the analysis terminal is configured to obtain a peer proximity histogram, a body orientation histogram, an image differential histogram, and an activity intensity histogram by splitting, in units of preset time intervals, the location information, the orientation information, the view information, and the motion information of the members included in the behavior information received from the plurality of member terminals, and to estimate the behavior distribution by combining the peer proximity histogram, the body orientation histogram, the image differential histogram, and the activity intensity histogram obtained for the plurality of members in units of the preset time intervals.
