Observing the Degree of Distortion in Coordinated Motor Actions

Abstract

Integrative motor actions have a characteristic that consists of multiple primitive motions. A time-series of movement includes a unit of integrative motor actions. Movement rhythm arises from coordinated efforts in this exercise. This study tries to support learning, focusing on double-under in rope-skipping. Double-under has major primitive motions: jumping and rotating wrists. There is timing difference between primitive motions. Thus, we design and develop a supporting system for learning timing difference in dynamic sense. The system measures learner’s data with wearable sensors, calculates the appropriate time and suggests feedback.
