A virtual reality goggle is a particular form of head-mounted display, which is a head-worn visual output device. It presents images on a near-eye screen or projects them directly onto the retina. A virtual reality glasses has in this regard still sensors for detecting movement of the head. Thus, the display of the calculated graphics can be adapted to the movements of the wearer of the virtual reality glasses. As a result of physical proximity, the displayed image areas of head-mounted displays are considerably larger than the freestanding screens and, in extreme cases, even cover the entire field of vision of the user. As the display follows the wearer's head movement through the head posture, it gives the feeling of moving directly into a computer generated landscape.

By means of such virtual reality glasses, therefore, a virtual reality can be represented, wherein virtual reality is usually the representation and simultaneous perception of reality in its physical properties in a real-time computer-generated, interactive virtual environment. A virtual reality glasses is thus particularly suitable to put a wearer of such glasses in a virtual world. In general, the higher the immersion - ie the proximity to reality - the better the virtual reality glasses fulfill their purpose.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

A total with 10 designated system for operating a virtual reality glasses 12 is in a schematic representation in 1 shown. The virtual reality glasses 12 includes a display device 14 , a sensor device 16 and a blower device 18 , The blower device 18 has a fan 20 and an air guiding device 22 on.

The display device 14 For example, it can have two separate displays which can be operated in such a way that a virtual environment can be displayed stereoscopically so that a wearer of the virtual reality glasses receives a three-dimensional impression of the displayed virtual environment. The sensor device 16 is adapted to a respective spatial position and change the spatial position of the virtual reality glasses 12 capture. At the blower 20 it may be, for example, a conventional fan, which is used in notebooks. By means of the blower 20 can be a carrier of virtual reality glasses 12 be subjected to an air flow. The louver 22 has, for example, adjustable flaps, by their respective setting an outflow direction of the means of the blower 20 generated air flow is variable.

The system 10 further comprises a detection device 24 , a control device 26 and a headphone 28 , The detection device 24 For example, it can be designed as a camera system which is designed to hold a position of the virtual reality glasses 12 in the room.

The control device 26 is signaling technology both with the respective elements 14 . 16 . 18 . 20 . 22 the virtual reality glasses 12 as well as with the detection device 24 and the headphones 28 coupled. The control device 26 can the headphones 28 depending on the means of the display device 14 to control the displayed virtual environment. In addition, the control device 26 adapted to the blower device 18 So the fan 20 and the adjustable louver 22 , depending on a detected spatial position and / or position of the virtual reality glasses 12 as well as in dependence on the means of the display device 14 to control the displayed virtual environment.

In 2 is a person or a carrier 30 shown which the virtual reality glasses 12 has set. The blower device 18 is in the vertical direction z of the virtual reality glasses 12 above the display 14 arranged. The blower device 18 is thus arranged and designed such that a conveyed by this air flow at by the carrier 30 attached virtual reality glasses 12 essentially on a forehead area 32 and a hair area 34 of the carrier 30 is alignable. Present is only the blower 20 the blower device 18 shown schematically, the louver 22 is not shown in the present illustration.

The strength and the outflow direction of one by means of the blower device 18 eligible airflow is dependent on the detected spatial position and / or position of the virtual reality glasses 12 and in dependence on the display device 14 changeable virtual environment. The control device 26 can both the blower 20 as well as the louver 22 accordingly control to the strength and / or the outflow of the means of the blower device 18 to change promoted air flow.

Based on 3 in which a virtual cockpit 36 of a motor vehicle is shown in detail, is a method for operating the virtual reality glasses 12 explained in more detail. The carrier 30 the virtual reality glasses 12 gets by means of the display device 14 the virtual cockpit 36 displayed during a virtual tour with the associated virtual car. The carrier 30 the virtual reality glasses 12 So sits as shown in 3 virtually in the driver's seat of the motor vehicle while using the virtual reality glasses 12 gets a virtual ride shown.

For example, the carrier 30 the virtual reality glasses 12 Changes to virtual blowers 38 inside the virtual cockpit 36 make and so z. B. virtually a Luftausströmrichtung the virtual fan devices 38 change. The change within the virtual environment, ie the virtual cockpit 36 , goes to the controller 26 transmitted. One by means of the blower device 18 the virtual reality glasses 12 provided airflow is taking into account the virtual head position of the wearer 30 opposite the blower devices 38 and making the change in the orientation of the virtual blower devices 38 by the control device 26 adjusted so that the air flow to the forehead area 32 and the hair area 34 of the carrier 30 so hits, so whether the carrier 30 actually sitting in a real car, in which he real the changes to the blower devices 38 has made.

It is also conceivable that the carrier 30 Changes to a virtual climate control facility 40 of the virtual cockpit 36 performs. For example, if he or she virtually raises the power of the fan, the controller will control 26 the blower device 18 , and in particular the blower 20 , such that the blower device 18 emitted air flow is also increased corresponding to the setting on the virtual climate control device.

Furthermore, it is also conceivable that the carrier 30 for example, a side window 42 inside the virtual cockpit 36 lowers during the virtual ride. Corresponding to the lowering of the window 42 and considering the virtual speed of the virtual motor vehicle, the controller controls 26 the blower device 18 such that on the one hand the strength and on the other hand also the outflow direction of the means of the blower device 18 promoted air flow is adjusted accordingly. Accordingly, for example, the blower device 18 activated if a virtual sunroof or virtual soft top not shown here is opened or closed during the virtual drive with the motor vehicle.

In addition, the strength and / or the outflow direction of the means of the blower device 18 the virtual reality glasses 12 promoted airflow in response to a virtual relative head position of the wearer 30 the virtual reality glasses 12 concerning the virtual cockpit 36 or the virtual motor vehicle adapted. Rejects the wearer 30 the virtual reality glasses 12 For example, his head so far to the left that this with his head inside the virtual cockpit 36 leaving the vehicle interior, his head 30 so through the opened virtual window 42 extends, so controls the controller 26 the blower device 18 such that it is for the wearer 30 the virtual reality glasses 12 feels like he's got his head actually extend out of a moving car through an open window.

The system 10 is thus designed such that the blower device 18 which part of the virtual reality glasses 12 is, depending on the virtual environment just presented and depending on the location and position of the virtual reality glasses 12 can always be operated such that the carrier 30 the virtual reality glasses 12 both in terms of the direction of flow and the strength of the air flow, is so acted upon by the air flow, as would be the carrier 30 actually move in reality and not within a virtual environment. This results in a particularly realistic and intense perception of the means of virtual reality glasses 12 represented virtual environment.
