Abstract
Computing a relative-head-orientation relative to a moving-reference. First and second data are received. The first data are indicative of a head-orientation of a head of a user. The second data are indicative of at least one of: a location, a motion, an orientation, a velocity and an acceleration of the user. A head-orientation is computed according to the first data. A moving-reference is updated by an adjustment toward the head-orientation, to produce an updated-moving-reference. The amount of adjustment is indicated by processing the second data. A relative-head-orientation is computed relative to the updated-moving-reference. Binaural audio is rendered in accordance with the relative-head-orientation.
