Cross-platform and cross-device pedometer system designed for healthcare services

Abstract

Physical activity is closely related to one's health status. Especially the intensity of physical activity is more important than other features for health benefits, which can be computed by the number of steps. With the advent of mobile devices, pedometer system can be implemented on mobile devices with their built-in sensors. However, due to the variety of types of platforms and devices, it is hard to ensure the consistency of step counting. In this paper, we propose a robust pedometer system for healthcare services, which ensures the consistent results of step counting upon heterogeneous platforms and multiple mobile devices. Based on the proposed system, we present the actual implementation of pedometer applications for different platforms and devices. We examine our implementation to verify that it is useful in real life with respect to the accuracy of step counting and battery consumption.
