Outline of Final Research Achievements

Most of the commercially available pedometers are not able to count steps accurately for ultra-low speed walking or irregular walking that are seen in elderly. In this study, we attempted to propose a novel step counting algorithm based on a gyroscope output and to develop a novel pedometer dealing with ultra-low speed walking. The algorithm and the pedometer had the average error rates of step counts were less than 10% for walking at less than 2 km/h. This suggests that a gyroscope is useful for step counting when subject walks at ultra-low speed.
