Experimental set-up.

(A) The six-degrees-of-freedom motion platform, with mounted chair (viewed from behind). (B) A participant sitting in the chair (viewed from the side) wearing a head-mounted display (Oculus Rift) for visual optic flow stimuli. The background stars depict what the participant sees in virtual reality (shown here for illustrative purposes only). (C) Flow of a single trial: after trial initiation, a 1-s (visual, vestibular or combined visual–vestibular) motion stimulus is experienced, after which the participant reports his/her heading discrimination (left or right). (D) Schematic representation of various heading directions. (E) Motion profile (the same for all stimuli; only heading direction was varied).
