Fig. 2.
Frontal projections of two-dimensional pointing vectors: distribution of gaze, Es(top row), head, Hs(middle row), and eye, Eh(bottom row) positions during control (A–C) and goggle (D–F) conditions, as viewed from behind one subject during head-free fixations toward the nine targets. Data points were selected as final fixation points at which eye, head, and gaze were <10°/sec. Cardinal targets were placed at 40° eccentricity and the oblique targets at 48°. Goggles restricted the effective visual range to ∼10° (denoted by the ring in F). Subject M.C.
