Effect of range of heading differences on human visual-inertial heading estimation. [PDF]
Exp Brain Res, 2019 Both visual and inertial cues are salient in heading determination. However, optic flow can ambiguously represent self-motion or environmental motion. It is unclear how visual and inertial heading cues are determined to have common cause and integrated vs perceived independently.
