An Overview of Gait Analysis and Step Detection in Mobile Computing Devices

Abstract

Acceleration sensors are widely deployed in consumer mobile radio terminals. This enables these terminals to provide gait analysis without requiring extra hardware. Gait analysis is useful for a variety of navigation, security, and biomedical applications. This paper provides an overview of the methods used for accelerometer-based gait analysis in mobile devices. It also shows how this analysis has been used in state-of-the-art applications. The most important problems to be solved to improve gait analysis and these applications are also identified.
