Consideration about the Characteristic of Velocity in the Speed Skating

Abstract

The purpose of this study is to explore architecture of performance support system for speed skating by visualizing player's physical action. We focus on the skating locus, velocity, acceleration, lumbar part rolling angle. Our system generates graphs of these data in time series variation. Therefore, we hope a player can get visual and quantitative feedback from these graphs, and can make positive self-reflection to assess his current skating. In this paper, the detail feedbacks to skaters about their velocity changes in the curve part with characteristics are explained.
