Throwing Darts Training Support System Based on Analysis of Human Motor Skill
Measurement, analysis, and modeling of human motor functions have been intensively studied because human motor skills are useful for various applications, such as digital archiving, sports training, rehabilitation, etc. Targeting the sport training support application, in the paper, we focus on a throwing darts movement that requires sophisticated control of the upper arm to realize precise throwing, and we investigate the relationship among motion trajectories, muscle activities, and throwing accuracy, from the viewpoint of release timing. Experimental results showed that skilled subjects demonstrated small temporal variance and a fixed timing of release; it was just before the moment their elbow angular velocity became maximum. Based on the findings, we developed a training support system for throwing darts. To evaluate validity of the proposed system, we executed training experiments of beginners.
