Estimated probabilities from the recorded head movements and the resulting posteriors. (A) Histogram for the pitch rotations in the casual condition as calculated with a parametrization of the fitted rotation matrices according to a Fick-gimbal convention and Gaussian fits obtained by minimizing the Kullback–Leibler divergence KL(p || q) between the Gaussian fits p and the histograms q (see Supplementary Material for the values). (B–D) Histograms and fits for the measured accelerations in head-coordinates. (E–G) Resulting acceleration posteriors for the standing, (E), waiting, (F), and action, (G), condition.
