In this research, we employ a small sensor and a small computer to develop a practice assistance system that supports athletes to exercise running through auditory feedback. This paper describes what different audio feedbacks inform runners of their performance to help them to acquire ideal running motion.

On a slackline, it is necessary to balance on an unstable line, and attention is paid to training the body trunk and posture balance of athletes and rehabilitation subjects. In this study, we developed a system to measure whole-body skeleton data on a slackline using a depth sensor. Using this system, experiment collaborators stood on one foot, and the data were acquired and analyzed. We also took questionnaire about body height and weight, and balance while watching the video, and compared with the data.

The author has conducted a survey that rhythm and phrase recognition when classical music performers score based sight-read about jazz adlib solo. Classical music performer generally takes the 1st and 3rd quarter as accented beat when they perform 4/4 beat phrases.

In this paper, the author reports the survey that records the processes that the classical music performers sight-reading jazz blues adlib phrases, changing the accented beat, then considers based on the results.
