Position-action based of elder unusual state detection for service Robot

Except for daily functions, service Robot in family environment should have more intelligence, one of the most important abilities is to detect the unusual state of clients, and then be able to call for help timely. In order to achieve this, we propose an approach for the service robot to detect unusual state of the elder in a real-time way and construct a solution to the problem of the research model, then proposed the integration of location - action characteristic information to determine the state of unusual state methods. Experimental results demonstrate that the model is feasible and can afford a judging gist to detect persons´ unusual state.
