Fig. 1 — View of the layout of the experimental workspaces from a participant’s perspective. The left panel shows the dual-obstacle setup, whereas the middle and right panels show the two single-obstacle setups. In the left panel, colored ovals show the configurations of LED stimulation: “top” stimulation, “right” stimulation (spatial), “left” stimulation (spatial), and “bottom” stimulation (catch trials). The starting location of the hand (black cross) was at (0, 0), and the front point (for the participant) of the target was at (0, 400). The left obstacle’s inside point was located at (–100, 200), and the right obstacle’s inside point was located at (100, 200).
