Head orientation biases eye position toward the same direction with head. Head orientation effect on eye distribution (slope) was not different significantly between the two viewing distances (paired t-test, t(19)=1.18, p=0.25) ; Head moved more widely (standard deviation of head distribution) with a 55 cm viewing distance than with a 110 cm distance (paired t-test, t(19)=5.76, p<.001).
