Self versus Environment Motion in Postural Control
Figure 3
Alternative models of postural control.
(A) Model that predicts constant gain of the postural response. (B) Model where amplitude of the postural response increases logarithmically with visual scene velocity and then saturates. (C) Model where the gain is initially constant and then monotonically decreases with the visual scene velocity. Here represents the visual scene velocity,
represents the true body velocity and
indicates the estimate of the body velocity calculated by the models.
