Life log analysis to guess living willingness of the elderly

In this paper, we propose the method to detect decline of living willingness of the elderly by analyzing information about location, posture and touched object. The details of an action in which decline of living willingness appears are recognized by applying these information to the state model. For example, in the case of cleaning, it is scrutinized whether the elderly move obstacles like chairs for cleaning or the elderly clean every corner of the room or not. The detection of decline in living willingness of the elderly live alone enables family in remote place or doctor to give appropriate advice and care early. It prevents the elderly from running into status to be cared.
