Examples of the signals and topography at different speeds. (a) Time-synchronized subset of scalp-EEG, ear-EEG, and IMU data for 5 s while moving at different speeds of 0, 0.8, 1.6, and 2.0 m/s. The EOGV channel was calculated by subtracting lower VEOG from upper VEOG. (b) EEG power topography in each channel of scalp-EEG and ear-EEG.
