Proposal and development of reversal motion skill leaning support environment

It is not easy to master reversal motion by himself / herself, because reversal motion uses different muscles that were not used in the dominant motion, and the reversal motion tend to be awkward. Dominant motion means the motion that a learner can play sports naturally with. In this background, we propose reversal motion skill self-learning environment that shows advice based on learner's dominant motion. In this study, we supposed that learners can play with dominant motions almost perfectly but can play poorly with reversal motions. The learners try to improve their reversal motion by referencing reversed dominant motion. In this process, when a learner input his/her reversal motion data, then the self-learning environment shows difference between the reversed dominant motion and reversal motion. The environment also tells how to improve the reversal motion.
