Abstract: A display arrangement for presenting video information to a human operator in a vehicle senses vehicle movements and movements of a head mounted display unit. Based on vehicle movements and movements of the display unit, a virtual scenario with background video data and application video data are generated to a display arrangement. The background video data are modified so background video moves opposite to vehicle movements. The application video data are modified so application video moves according to vehicle movement. A perspective onto the application video can be modified based on relative movements of the display unit with respect to the vehicle. This may reduce conflicts between sensory impressions of the vestibular system and eyes of the operator because movements of the vehicle and movements of the display unit are considered when generating and modifying the background and application video data presented to the operator.
