Abstract
Tracking means is utilised to track a position and an orientation of a head of user(s) sitting inside a vehicle. A vehicular acceleration signal is determined for a first time period, based on at least one of: an acceleration, an orientation of the vehicle sensed by sensor(s) during the first time period. Transformation(s) is/are applied to the vehicular acceleration signal to generate a head acceleration signal for a second time period, wherein the head acceleration signal is indicative of a change in at least one of: an acceleration, the orientation of the head. An expected head movement of the user(s) is determined, based on the head acceleration signal. The position and the orientation of the head being tracked by utilising the tracking means are refined, based on the expected head movement.
