1. A system comprising:
tracking means;
at least one sensor employed to detect a current setting of at least one adjustable seat parameter of a vehicle; and
at least one processor configured to:
utilise the tracking means to estimate a plurality of potential positions of a head of a user sitting on a seat of the vehicle;
determine a three-dimensional (3D) volume where the user's head is likely to be present, based on the current setting of the at least one adjustable seat parameter;
detect whether at least one of the plurality of potential positions of the head lies outside the 3D volume; and
when it is detected that at least one of the plurality of potential positions of the head lies outside the 3D volume, consider the at least one of the plurality of potential positions as an outlier, and determine a correct position of the head of the user as one of the plurality of potential positions of the head that lies within the 3D volume.
