Design And Implementation Of A Human Activity Monitoring System Based On Smart Mobile Terminal

With a highly integrated hardware technology matures, sensor technology rapiddevelopment, it provides a material basis for the intelligent mobile terminals based humanmotion study, and mature model approach provides a theoretical research base for the study ofthe theory. The recent emergence of wearable devices, the motion calculation is separatedfrom intelligent mobile, and standalone accessories for sports state identification andmonitoring, as well as the intelligent mobile terminal as a transit station and the network as aback-end server. This paper on the Android and iOS platform presents the design andimplementation of human behavioral surveillance system based on intelligent mobileterminal.1. In the Android platform, it monitors human behavior from two sides,First, it bases on the three-axis acceleration sensor, which is responsible for monitoringthe state of motion throughout the day, which records steps at each time the movement, whichcalculates energy and distance, which can do sedentary detection and fall detection, statisticalnumber of steps daily exercise type. At the same time, the preservation of the timing data ofsports, ensure the data is not easy to loss.Second, it bases on the GPS sensor trajectory tracking, in addition to locate the currentposition, but also to the SQLite database records the user movement through the line, and itcan be share from network sharing, and use of third party Offline Maps API to save provincialtraffic.In addition, it seizes the stationary state the special motion state, and adaptive controlsthe sampling frequency of acceleration sensor, reduced to1%to5%charge per hour.2. In the IOS platform, it uses Objective-C language implementation of human movementstate recognition algorithms, which distinguish the different movements, but also have thefunction of the fall detection. In order to implement the interface friendly interaction, it usesstoryboard system. The label at the bottom of the form of navigation design used in the maininterface, allows users to switch quickly in any two interface.
