碩士 === 輔仁大學 === 電機工程學系碩士班 === 102 === In this paper we use a smartphone with three-axis accelerometer to design and implement a monitoring system to detect falls and measure walking steps. Measure walking steps is use a multiple judgment method to improve the accuracy of measuring walking and running steps. We also analyze the acceleration waveform include the motion common behavior in daily life to improve the accuracy of detect falls. As well as voice interaction function, global positioning systems and exercise information. If there is indeed an accident. Voice interaction function would ask if the user needs help, and allow the user to respond to the question either by speaking to the phone or by pressing a designated area on the screen. This design can make calls, and send SMS (Short Message Service) with an address converted from the GPS (Global Positioning System) latitude and longitude data. Convenient ambulance personnel or family can find user in the shortest time. And we use the mathematical formulas for calculating the amount of exercise information. Our system is the basis for the smartphone, so the system has a convenient carrying characteristics.
