A Learning Environment for Playing String Instruments Based on Finger Motion Analyses

二胡是一种有弦有弓的乐器。我们测量了初学者在玩二胡时的手指运动。我们还分析了初学者在弹奏二胡时的手指动作偏误。此外，我们还为二胡的演奏开发了一个技能学习环境。具体地说，当学习者将左手手指放在琴弦上时，学习者指尖上的磁性位置传感器可以检测学习者的手指位置。学习环境将学习者的手指顶部位置和学习者应该将其手指顶部放置的正确位置可视化。学习者可以在视觉上发现学习者的指尖位置和正确位置之间的错误。

Er-hu is one of musical instruments which have strings and bows. We measured novice learners' finger motions during playing Er-hu. We also analyzed novice learners' errors of finger motions during playing Er-hu. In addition, we developed a skill learning environment for playing Er-hu. Specifically, Magnetic position sensors on learner's finger tops detect positions learner's finger positions when he/she put his/her left hand fingers on strings. The learning environment visualizes the learner's finger top positions and correct positions that the learner should put his/her finger tops. The learner can find errors between learner's finger top positions and correct positions visually.
