RT Journal Article A1 Saunders, Jeffrey A. A1 Niehorster, Diederick C. T1 A Bayesian model for estimating observer translation and rotation from optic flow and extra-retinal input JF Journal of Vision JO Journal of Vision YR 2010 DO 10.1167/10.10.7 VO 10 IS 10 SP 7 OP 7 SN 1534-7362 AB We present a Bayesian ideal observer model that estimates observer translation and rotation from optic flow and an extra-retinal eye movement signal. The model assumes a rigid environment and noise in velocity measurements, and that eye movement provides a probabilistic cue for rotation. The model can simulate human heading perception across a range of conditions, including: translation with simulated vs. actual eye rotations, environments with various depth structures, and the presence of independently moving objects.
