Method for operating a virtual-reality system , wherein: - a velocity with which a person wearing virtual-reality glasses performs a change of position within a capture space is captured; characterised in that - if the person wearing the virtual-reality glasses moves within a predetermined portion of the capture space , a movement velocity of the person is captured and a first virtual velocity is predetermined, which is greater than the captured movement velocity of the person by a predetermined factor; - a virtual observation position within a virtual environment is changed in accordance with the first virtual velocity, while at the same time a virtual object arranged within the virtual environment is displayed by means of the virtual reality glasses from the changing virtual observation position, whereby it is ensured that in the case of limited space within the capture space a wearer of the virtual reality glasses can move virtually around a virtual object that has relatively large dimensions in comparison to the real dimensions of the capture space , without leaving the capture space ; - the portion is predetermined in the form of an outer region, which surrounds an inner region of the capture space ; - the factor is predetermined in dependence on the virtual dimensions of the virtual object ; and - a second virtual velocity, which corresponds to the captured velocity of the person , is predetermined if it is captured that the change of position occurs within the inner region of the capture space , wherein the virtual observation position is changed within the virtual environment in accordance with the second virtual velocity while at the same time the virtual object arranged within the virtual environment is displayed by means of the virtual reality glasses from the changing virtual observation position. - a velocity with which a person wearing virtual-reality glasses performs a change of position within a capture space is captured; - if the person wearing the virtual-reality glasses moves within a predetermined portion of the capture space , a movement velocity of the person is captured and a first virtual velocity is predetermined, which is greater than the captured movement velocity of the person by a predetermined factor; - a virtual observation position within a virtual environment is changed in accordance with the first virtual velocity, while at the same time a virtual object arranged within the virtual environment is displayed by means of the virtual reality glasses from the changing virtual observation position, whereby it is ensured that in the case of limited space within the capture space a wearer of the virtual reality glasses can move virtually around a virtual object that has relatively large dimensions in comparison to the real dimensions of the capture space , without leaving the capture space ; - the portion is predetermined in the form of an outer region, which surrounds an inner region of the capture space ; - the factor is predetermined in dependence on the virtual dimensions of the virtual object ; and - a second virtual velocity, which corresponds to the captured velocity of the person , is predetermined if it is captured that the change of position occurs within the inner region of the capture space , wherein the virtual observation position is changed within the virtual environment in accordance with the second virtual velocity while at the same time the virtual object arranged within the virtual environment is displayed by means of the virtual reality glasses from the changing virtual observation position. <EOS>
