摘要： A method and system for providing head orientation relative to an adaptive reference orientation, implemented by a processing unit and comprising receiving head data from a head sensor, said head data describing a first head orientation of a user; receiving second data from a second sensor; adapting said adaptive reference orientation by moving it at least partly towards said first head orientation by an amount which is varied at least partly in accordance with said second data, thereby generating a new adaptive reference orientation; and generating, in accordance with said first head orientation and said new adaptive reference orientation, a second head orientation of the user as said first head orientation relative to said new adaptive reference orientation.

摘要： A method and system of providing an adaptive reference orientation usable for determining a relative head orientation of a user, the method being implemented by a processing unit and comprising: repeatedly providing: receiving first data sensed by one or more sensors, said first data being indicative of a user's head orientation; obtaining a new adaptive reference orientation by moving a current adaptive reference orientation at least partly towards said indicated head orientation, by an amount which is varied at least partly in accordance with second data, said second data having been sensed by one or more sensors and being indicative of changes of a current frame of reference of the user; computing head orientation relative to said adaptive reference orientation; and using said new adaptive reference orientation as a current adaptive reference orientation for a next repeat of operations.

摘要： 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.
