(A) Experimental setup in this study. Each subject was instructed to walk on a treadmill at 1 mph while looking at an avatar in a VE in front of them. Recorded data included electroencephlography (EEG), lower limb joint angles of both left and right leg, and accelerations of head, left heel, and right heel. Locations and EEG channel labels were also displayed. Channels marked with an "x" were not used in the decoder. (B) Illustration of a full walking gait cycle. (C) Raw data during pre-, early-, mid-, late- and post-exposure in one day.
