Results of feedback sessions for dry vs. full cap.

Feedback gel cap (top) reports feedback data from an earlier study (3). The first line shows the bit/min information transfer rate of 1D cursor control averaged over 8 sessions consisting of 25 trials each. The second line gives the average percentage of correct trials and the third and fourth lines provide the average time per trial and the peak performing session result. Feedback dry cap (middle) as above. Note that here 4 sessions of 100 trials each were evaluated. Also the peak performance was computed as the best 25 consecutive trials. The lower part (bottom) of the table summarizes the relative loss in performance of the respective setups for the subjects. Note that a negative sign indicates lower performance of the dry electrode cap. ��% of MVC�� stands for the power of feedback trials, as compared to the maximum voluntary contraction (MVC). EMG-fb stands for the EMG activity in the actual feedback trials, as compared to the preparatory phase of each feedback trial, EMG-pre.顶部的凝胶型反馈帽（Feedback gel cap）取自一项早期研究（参考文献3）的反馈数据。第一行展示了一维光标控制任务的信息传输速率（单位：比特/分钟），该速率为8次实验单元的平均值，每个实验单元包含25个试次。第二行给出了正确试次的平均占比；第三行与第四行分别给出了单次试次的平均耗时，以及表现最佳的实验单元结果。 中部的干式反馈帽（Feedback dry cap）相关内容同上。需注意，本次实验共评估了4次实验单元，每个实验单元包含100个试次；此外，本次的最佳表现被定义为连续25个试次中的最优结果。 表格的下部（底部区域）总结了各实验设置下受试者的性能相对损失。需注意，负值代表干式电极帽的表现更差。 标注为“% MVC”的指标代表反馈试次相对于最大自主收缩（maximum voluntary contraction, MVC）的功率；EMG-fb代表实际反馈试次中的肌电（electromyography, EMG）活动水平，其参照基准为每个反馈试次的准备阶段（即EMG-pre）。
