A novel application of inertial sensor based foot-mounted wearable electronic device

Wearable electronic devices have experienced an increasing development with the advances in the semiconductor industry and are receiving more attention during last decades. This paper presents a brand new application of inertial sensor-based foot-mounted wearable electronic device: game play. The introduced device is able to monitor and identify human foot stepping directions in real time, and coordinate these motions to control the player operation in games. This paper provides an overview of the previously-developed system platforms, introduces the main idea behind this novel application, and describes the implemented human foot moving direction identification algorithm. Practical experiment results demonstrate that the proposed system is capable of recognizing five foot motions: jump, step left, step right, step forward, and step backward, and has achieved a convincing performance for different users. The functionality of the system for real-time application has also been verified through the practical experiments.
