A Novel Snowboard Training System Using Visual and Auditory Feedback

Abstract

In snowboard training, it is very important to perceive a gap between the perceived movement and the actual body movement. Previous training systems don’t have sufficient function in that they only use either visual or auditory feedback, or only display value such as velocity. In this paper, we propose and develop a novel snowboard training system that assists snowboard training using visual feedback that has immediate effect and auditory feedback that has long-term effect. This system consists of four components: (1) a center of pressure detection (COP) device that detects weight shift using pressure sensors, (2) a posture estimation device that calculates orientation of a board using an IMU sensor, (3) a visual feedback device that displays the current position and the ideal position on the smart glasses, (4) an auditory feedback device that indicates direction and a gap between the current position and the ideal position using pitch and volume of sound. We conducted an experiment to verify feasibility to enhance motor learning using the system. As the results of experiment with three participants, we confirmed that our system could decrease the gap and standard deviation between the perceived movement and the actual body movement even after removing the system, and could assist the proper body control. In conclusion, we developed a novel snowboard training system and confirmed our system has a feasibility to enhance motor learning using visual and auditory feedback.
