ABSTRACT

In this paper, it was suggested method to recognize the motion of a person(lying, sitting, walking, running) using fuzzy inference and wireless biological signal processing system. These are to perceive the motion of the person. Furthermore, the information of motion is indispensable parameter for Context Awareness(CA). In the present study, ADXL 202JE accelerometer sensor was used to measure for checking the continuance motion, biological quantity of motion, and motion pattern of a person. The measured data was transmitted to CA server by Radio Frequency(RF). From the present result, we confirmed that it is difficult to decide the motion of walking and running with only the magnitude of the Longitudinal Accelerometer Average Value(LAAV) and moreover the covariance of LAAV in any block is very useful for CA of walking and running.
