Title
(EN) Method for setting a viewing direction in a representation of a virtual environment
Abstract
(EN)

A method for setting a direction of view in a representation of a virtual environment is disclosed. The method includes recording a known object in a real environment using a recording device. Further, the method includes determining a rotational offset of the direction of view in the representation of the virtual environment around a yaw axis of the representation of the virtual environment based on the recording of the object, a known position of the recording device in the real environment and a current direction of view in the representation of the virtual environment. The method further includes rotating the direction of view in the representation of the virtual environment by the rotational offset.
