EEG and IMU data

60 EEG channels and 4 EOG channels were recorded at a sampling rate of 100 Hzfrom the Brain Products actiCap System.46<br> The electrodes were placed and labeled using a modified version of the 10-20 system5. Four posterior electrodes – TP9, TP10,47<br> PO9, PO10 – were reallocated as vertical and horizontal EOG sensors for the recognition and removal of eye movement/blink48<br> artifacts from the 60 EEG channels using an H∞ filter6. Electrodes FT9 and FT10 were also moved to the standard AFz and49<br> FCz locations respectively, and the ground and reference electrodes were then placed on the left and right ears. To help maintain50<br> low impedances, electrolytic gel was injected between each electrode and the subjects’ scalps. Impedances were tested and51<br> recorded before and after each session. The 3D spatial locations of all 64 electrodes were digitally scanned and recorded for52<br> most sessions (see Table 1) using the Brain Products CapTrak system; these specific coordinate locations could be used for53<br> subject- and session-specific EEG source localization and to ensure consistent electrode placement across sessions. Finally,54<br> an elastic mesh was fitted over the scalp and EEG cap to help keep the electrodes in place and reduce motion artifacts due to55<br> cable movement during the recording process. In addition to EEG data, each subject was fitted with inertial measurement units56<br> (Opals, APDM Inc.) in the center of each subject’s foreheads and on the back brace of the exoskeleton. T

本研究通过Brain Products actiCap脑电采集系统以100 Hz的采样率，同步采集了60通道脑电图（Electroencephalogram, EEG）与4通道眼电图（Electrooculogram, EOG）信号[46]。电极的安放与命名采用改良版国际10-20系统[5]。其中4个后部电极——TP9、TP10、PO9、PO10——被重新用作垂直与水平眼电传感器，用于通过H无穷（H∞）滤波器识别并去除60通道EEG信号中的眼动/眨眼伪迹[6,47]。电极FT9与FT10分别被调整至标准电极位置AFz与FCz[48]，随后将接地电极与参考电极放置于左右耳部。为维持较低的电极阻抗，在每一枚电极与受试者头皮之间注入电解凝胶[49]。每个实验时段前后均会测试并记录电极阻抗[50]。多数实验时段中，使用Brain Products CapTrak定位系统对全部64枚电极的三维空间位置进行数字化扫描与记录（详见表1）[51-52]；这些个体化、时段专属的坐标位置可用于EEG脑电源定位分析，同时确保不同实验时段的电极安放位置保持一致[53]。最后，在头皮与脑电帽外侧套戴弹性网罩，以固定电极位置并减少记录过程中线缆移动带来的运动伪迹[54-55]。除EEG数据外，每名受试者还在额头中央以及外骨骼背部支架处安装了惯性测量单元（Inertial Measurement Unit, IMU）——型号为Opals，产自APDM公司[56]。
