• We developed a new watch with pedometer function (Cal.S670). The watch comprises a three-axis acceleration sensor to count steps. Then, we can detect a touchdown impact (landing impact) to occur in the direction that is different from a run in a walk. Also we developed new algorithm to count steps from data of three-axis acceleration sensor. In this way, we can count steps during not only running, walking, but also changing position of the watch. Finally, we were able to achieve the high-precision detection by optimizing a detection condition.
