A typical example of circular tracking movement which was performed in 3D VR space. (A) Circular tracking movement on the frontal plane (ROT(0) condition). (B) Circular tracking movement on the sagittal plane (ROT(90) condition). For A and B, upper graphs are circular tracking movements under the monocular vision and lower graphs are circular tracking movements under the binocular vision. For all traces, three graphs show target paths (green line) and tracer paths (black line) on the front (left graph), the upper (center graph), and the side (right graph) for subjects’ eyes in experiment task.
