Abstract

<p>We aim to develop a swimming motion coaching support system for beginner and/or intermediate swimmers by using single inertial sensor. In this paper, we develop a prototype to visualize the acquired sensor data and display the timing information of swimming motion such as respective stroke and turn. Our previous proposed estimation methods of the swimming motion are implemented in the prototype. We carry out a questionnaire survey to evaluate the visibility, effectiveness and reliability of the prototype. As the result, although there are various opinions on the estimation error of respective stroke and turn, it is suggested that the prototype system is required at the actual training scene.</p>
