Abstract:
The purpose of this research are to analyze and identify the activities of the elderly and risky activities causing harm to them by using the tracking device for the elderly.For this device, it is a small device similar to a necklace with a three-axis acceleration sensor inside for collecting data about body movements characteristic of the elderly. The researcher conducted and collect databy using participants wearing a tracking device to analyze about daily activities such as walking, running, sitting, stand up and sleeping activities. In addition, the researcher collected information about falls. All of data analysis is occurred within a unit tracking device which is small processors and sent the data through frequency range of 2.4 GHz. by using Time-domain techniques and Frequency-domain techniques. The research of this study indicated, Time-domain technique by using the signal vector magnitude, the energy generated by the movement and the variation of the angle form, can distinguish the type of activities in each category however, the movement of the human body are similar with the basis of a reference time signal. It is necessary to use a Frequency-domain techniquebecause the frequency of events and the energy of the occurred spectrum can verify the accuracy of the analysis and increase the accuracy of the indicator behavior.For detecting activity test of walking, it was 95 percent, activity of running 97.5 percent, activity of sitting 92.5 percent, activity of sleeping 87.5 percent, activity of standing 97.5 percent, activity of fall 95 percent and overall activity was for 94.16 percent.
