| Outline of Final Research Achievements |
In this research, we propose an algorithm to evaluate swimming performance and develop a system included it by using a single inertial sensor and deep learning. Algorithms to recognition of swimming style and detect starting and ending timing of each stroke and turn motion are embedded into the system. They are developed by the random forests and deep learning. As a result, swimmers can know each motion performance (each stroke and turn).

| Academic Significance and Societal Importance of the Research Achievements |
これまでの一般的なトレーニング現場では、1回1回のストローク（1回目は1.2sec, 2回目は1.3secなど）のパフォーマンスを競技終了後即座に知ることは困難であった。しかし、本研究で開発されたシステムにより、競技者はこれを競技終了後即座に知ることが可能となる。これにより、自らの動作のどこが悪かったのか、知る機会を得ることができるため、パフォーマンス向上に寄与すると考えられる。
