A method () to determine a present position () of an object (). The method () comprises using () an optical positioning system () to determine a first preliminary position () and using () a radio-based positioning system () to determine a second preliminary position (), determining () a supposed position () on the basis of one of the preliminary positions () and combining () the supposed position () with a previous position () of the object to determine the present position () of the object, if the supposed position () is based on a different positioning system () than a previous supposed position ('). A positioning system () with combined optical and a radio-based determination of a position of a tracker () and a tracker () with an active light source ().

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.
