1. A generation method of generating an at least 2-dimensional virtual representation of a real environment, the generation being implemented by a mixed virtual reality headset intended to be worn by a user, the mixed virtual reality headset being associated with at least one interface device distinct from the mixed virtual reality headset, the generation method comprising:
acquiring relative coordinates in the real environment, corresponding to a position of the interface device in the real environment;
following an interaction of the user on the interface device, determining a corresponding point in the virtual representation depending on the relative coordinates of the position of the interface device in the real environment; and
generating the virtual representation from at least the point associated with the relative coordinates of the acquired position of the interface device, said virtual representation being a 2D or 3D scale plan of the real environment.
