The invention relates to a method for operating a virtual reality headset in a vehicle, in which at least an instantaneous orientation of the virtual reality headset is determined by means of an inertial measurement unit arranged on the virtual reality headset, and a corresponding control device. Based thereon and on vehicle localisation data, a virtual perspective of a virtual environment displayed in the virtual reality headset is simulated. Therein, a relative arrangement of the virtual reality headset with respect to the vehicle interior is determined through an optical capture device arranged on the virtual reality headset. Corresponding data from the inertial measurement unit and the optical capture device are fused together to determine a corrected orientation or pose of the virtual reality headset with respect to the vehicle interior for simulating the virtual perspective.
