sEMG Date

In the experiment, participants were asked to perform 16 predefined gesture-motion protocols as shown in Fig. Each participant performed 1 experiment in the order of Fig, performing each movement 2 times with a 1-minute break in between each set of movements. Since the measured sEMG signals were almost harmless to the subjects, they could stop the experiment at any time to prevent any discomfort. At the beginning, one should remain relaxed, the upper limb should be placed horizontally on the table, the elbow should be lightly supported, the palm of the hand should be down, and the fingers should be slightly flexed. All operations are started from this static position.

本实验中，要求受试者完成如图所示的16种预定义手势动作规程。每位受试者需按照图示顺序完成一轮实验，每项动作重复执行2次，每组动作之间设置1分钟的休息间隔。由于所采集的表面肌电（sEMG）信号对受试者几乎无伤害，受试者可随时终止实验以避免任何不适。实验初始阶段，受试者需保持全身放松，上肢水平放置于桌面，肘部轻靠支撑，手掌朝下，手指呈轻度屈曲状态。所有操作均需从该静态起始姿势开始执行。
