Abstract: A method represents an environment via a display unit arranged on a person and visible for the person as a display image within the scope of a simulation. The simulation is carried out in an interaction environment, wherein a number of actuatable interaction elements are arranged in the interaction environment. An interaction environment image capture, depicting the interaction environment, is created by use of a first image capturing unit arranged on the person or relative to the person. A position of the person is determined in the interaction environment and based on the position of the person an environment image is provided. An image mask is provided which depicts the individual interaction elements contained in the interaction environment image capture and is represented in the display image. The interaction environment image capture and the environment image are superimposed using the image mask and then displayed on the display unit.
