Abstract: Embodiments concern a method for providing information to a user of a vehicle via a display device that is worn by the user. The method comprises providing a principle axes rotation coordinate system (Vxyz) that defines a vehicle orientation relative to a world coordinate system (Wxyz) of a reference world space; providing at least one display device coordinate system (Dxyz) that defines a display device orientation relative to the vehicle coordinate system; and providing a symbol coordinate system (Sxyz) that is spatially fixed with at least one first symbol to be displayed on the display device and that defines three symbol rotation axes that are orthogonal to each other; and spatially fixing at least one of the symbol rotation axes (Sα) to a vehicle principal axis of rotation descriptive of an orientation of the vehicle.
