Outdoors real-time information analysis system for elderly based on smart phone

Aging population is growing, and the young people are more concerned about the real-time condition of the elderly. This paper aims to propose a real-time monitoring system, obtaining and analyzing the outdoors dynamic information of the elderly, which is composed of three cooperative modules (mobile client, server and sensor). The sensor is equipped with a Bluetooth module to the data transmission, and the server is mainly responsible for distinguishing between the falling attitude and normal activity and record the outdoors motion path of the elderly. The result is displayed on the client, including the mobile phone and browser. If the abnormal condition emerges, the phone of the elderly immediately alarms and the server sends message to ask their children and relevant departments for help at once. The system shows a good real-time performance and an accurate result.
