Abstract :
Efforts have been made to measure the distance traveled by humans in motion, in ways that are compact and accurate, for a long time. There are several ways to measure the distance moved by walking or running in daily life, some of which already use commercial products, but those methods are inaccurate. In this study, a new method is provided using ultrasonic sensors, and this is the fundamental study. The newly devised ´Portable Walking Distance Measurement System´ was developed using ultrasonic wave characteristics and has approximately 90% accuracy. This result provides an opportunity to estimate human activities and the developed system would provide more comfort and an exact way to measure the walking distance in daily life and could be applied to exercise.
