Estimation of Walked Distance Using Inertial Sensors under Real Conditions

this paper focuses on the comparison of the three most cited algorithms for calculation of walked distance in human, from accelerations measured by inertial sensors placed near the center of mass of human body. The algorithms were tested in real conditions during short walk travels, up to 10 meters, which are typical distances inside the flat. We used two different sensors -one included in a smart phone and our own developed sensor. Results show the differences between tested algorithms in real conditions and their possibilities in real applications, and show better results obtained with the model of the inverted pendulum.
