This is an important pre-requisite for pursuing strength and speed during playing. The training method can be targeted to solve some common problems, and guide students to consciously feel the touch and the change of tone, listening with ears, controlling with fingers to achieve solid and soft balanced unity.展开更多

Surface EMGs are hannless to the humnan body and easily done. However, they do not reflect the activity of specific nerves or muscles, unlike invasive EMCs. On the other hand, the non-invasive type is difficult to use for discriminating various motions while using only a small number of electrodes. Surface EMG data in this study were obtained from four electodes placed around the forearm. The motions were the flexion of each 5 single fingers （thumb, index finger, middle finger, ring finger, and little fingers）. One subject was trained with these motions and another left was untrained. The maximum likelihood estimation method was used to infer the finger motion. Experimental results have showed that this method could be useful for recognizing finger motions.The average accuracy was as high as 95%.展开更多
文摘By analyzing several effective finger practices, it is possible to consolidate the basic skills to help students adjust and establish a good touch mode. This is an important pre-requisite for pursuing strength and speed during playing. The training method can be targeted to solve some common problems, and guide students to consciously feel the touch and the change of tone, listening with ears, controlling with fingers to achieve solid and soft balanced unity.
