Fig. 6.

Simulation (sim) of the model on two movements, one with residual VOR gain of 0.24 (A, C, E) and one with residual VOR gain of 0.7 (B, D, F). Black dashed lines represent head movement, black solid lines represent eye movement, gray solid lines represent the estimate of head movement predicted by the model (pG*head movement) and gray dotted lines represent eye movement simulations. Eye movement is inverted for the comparison with head movement. In A, the estimate of head movement is inaccurate (pG = 0.6), thus the triggered saccade is not adequate (C) and when the predicted gaze reaches 0°, stopping the saccade, the actual gaze correction is too small, leaving a final gaze error of 5° (E). In B, the estimate of head movement is accurate (pG = 0.94), hence the size of the corrective saccade is correct (D) and the final gaze position nearly reaches 0° (F).
