Abstract
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.
