Abstract

This paper proposes a behavior log creation support system realized by sensor fusion. The system is equipped with a human pose sensor and a staying room sensor as the pose/position sensors as well as a voice sensor and a PC (personal computer) utilization history sensor to detect the target of the behavior. The human pose sensor classifies human behavior into standing, sitting and walking. The staying room sensor records a name of a room where the user stays. The voice sensor detects the conversation, which appears when the user is with someone else. The PC utilization history sensor records not only whether a PC is used or not but also the names of the application software to serve as a detector of the behavior target during computer work. The measured data from these sensors is displayed to the user to support the creation of a behavior log, i.e. to support the user to recall and to input contents and targets of his or her behavior. The experiment of making use of the sensors and creating a behavior log proved that the recorded events of the behavior log per all events improved from 60% with no support to more than 90% with support of the system. The result quantitatively shows the capability of human behavior logging support of the system.
