Description

The invention relates to a method for operating a arranged in a motor vehicle virtual reality glasses and a virtual reality system. Furthermore, the invention relates to a motor vehicle with a virtual reality system.

A virtual reality system in the sense of the invention is to be understood as a system by means of which a virtual reality can be visually displayed and, if appropriate, also reproduced acoustically. The virtual reality system can include a virtual reality glasses for displaying virtual objects and possibly even a headphone for sound reproduction.

A virtual reality glasses is a specific form of a so-called head-mounted display, so a portable on the head visual output device. It presents images on a near-eye screen or projects them directly onto the retina. A virtual reality glasses usually has additional 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 glasses. Due to the physical proximity, the displayed image areas of head-mounted displays are considerably larger than the free-standing screens and, in extreme cases, even cover the entire field of vision of the user. Because the virtual reality goggle display follows all of the wearer's head movements, 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, whereby as a virtual reality usually the representation and simultaneous perception of reality in its physical properties in a real-time computer-generated, interactive virtual environment is called.

Such a virtual reality system can be used for example in a motor vehicle, so that a vehicle occupant can put on and use the virtual reality glasses while driving. The vehicle occupant can display various virtual environments, for example a film, a computer game or the like, by means of the virtual reality glasses. If this happens during the journey with the motor vehicle, nausea may possibly be caused in the vehicle occupant wearing the virtual reality goggles. This is due, among other things, to a divergence between a virtual environment displayed by means of the virtual reality glasses and the proper movement of the vehicle occupant perceived by the equilibrium organ.

It is therefore the object of the invention to provide a method for operating a virtual reality system as well as a virtual reality system, by means of which the reproduction of virtual contents is made possible without a vehicle occupant having a virtual reality glasses to play the virtual content, causing nausea.

The object is achieved by a method for operating a virtual reality glasses arranged in a motor vehicle and by a virtual reality system having the features of the independent patent claims. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims.

In the method according to the invention for operating a virtual reality spectacle arranged in a motor vehicle, the movement of the motor vehicle is detected. A first virtual environment is displayed by means of the virtual reality glasses in a first display region of the virtual reality glasses, wherein the first virtual environment is displayed independently of the detected movement of the motor vehicle. Simultaneously, a second virtual environment is displayed by means of the virtual reality glasses in a second display region of the virtual reality glasses, wherein the second virtual environment corresponding to the detected movement of the motor vehicle is displayed. In other words, therefore, there is a permanent detection and evaluation of the movement of the motor vehicle, wherein the permanently detected movement of the motor vehicle is considered in the display or display of the second virtual environment by means of the virtual reality glasses. Virtual reality glasses make it possible for a vehicle occupant, if he has put on virtual reality glasses, to present media content in a special way. For example, vehicle occupants of a vehicle may enjoy a movie on a virtual screen, such as in a movie theater, while wearing such virtual reality glasses. However, when the vehicle is in motion, the divergence between a virtual environment shown by the virtual reality goggles and the self-motion sensed by the body of balance of the respective wearer of the virtual reality goggles may occur - especially when cornering, accelerating or decelerating the motor vehicle - create nausea.

To circumvent this undesired effect, it is provided in the solution according to the invention, in addition to the first display area, in which the media contents are displayed by means of the virtual reality glasses in the form of a virtual environment, in the second display area of the virtual reality glasses another virtual environment representing which is represented corresponding to the detected movement of the motor vehicle. In other words, this second virtual environment moves adequately to the real relative movement of the environment to the moving motor vehicle. As a result, the wearer of the virtual reality glasses gets a kind of optical feedback on how the motor vehicle - and thus the wearer of the virtual reality glasses - actually moves within the real world. As a result, there is no longer any discrepancy between the movement perceived by the wearer of the virtual reality glasses, in particular acceleration, in the real world and the first virtual environment additionally displayed by means of the virtual reality glasses, which is independent of the movement detected by the virtual reality glasses Motor vehicle is shown. By means of the method according to the invention, therefore, the reproduction of virtual contents is made possible without causing nausea in a vehicle occupant who is wearing virtual reality glasses for the purpose of displaying the virtual contents.

In an advantageous embodiment of the invention, it is provided that a landscape corresponding to the detected movement of the motor vehicle is displayed as the second virtual environment. This gives the wearer of the virtual reality glasses in a simple way, an optical feedback on the actual movement of the motor vehicle and thus his own movement, whereby the said nausea in the wearer of the virtual reality glasses can be avoided.

According to an alternative advantageous embodiment of the invention, it is provided that the vehicle environment moving relative to the motor vehicle is detected by means of a camera system and displayed as the second virtual environment. As a result, the actual vehicle environment moving relative to the motor vehicle can be displayed in a particularly realistic manner. As a result, it may be possible to further prevent the nausea from occurring in the wearer of the virtual reality glasses.

According to a further advantageous embodiment of the invention, it is provided that the longitudinal movement of the motor vehicle is detected and taken into account when displaying the second virtual environment. In this case, preferably both the speed of the motor vehicle in the longitudinal direction and the acceleration of the motor vehicle or the deceleration of the motor vehicle in the longitudinal direction are detected and taken into account when displaying the second virtual environment. For example, if the motor vehicle brakes relatively sharply, this is taken into account when the second virtual environment is displayed, for example by displaying an indicated moving landscape also slowing down as it passes according to the braking of the motor vehicle. If, for example, the motor vehicle drives particularly fast over a motorway, then the displayed moving landscape is displayed in such a way that it virtually passes by the wearer of the virtual reality glasses in accordance with the speed of the motor vehicle. By detecting and taking into account the longitudinal movement of the motor vehicle when the second virtual environment is displayed, it is possible to ensure that no nausea occurs in the wearer of the virtual reality goggles when viewing the first virtual environment.

In a further advantageous embodiment of the invention, it is provided that the transverse movement of the motor vehicle is detected and taken into account when displaying the second virtual environment. In this case, in particular, the lateral accelerations of the motor vehicle occurring during cornering can be taken into account and recorded so as to adapt the displayed second virtual environment to corresponding cornering or the like with respect to their presentation. This also helps to reduce the risk of nausea in the wearer of virtual reality glasses.

A further advantageous embodiment of the invention provides that the vertical movement of the motor vehicle is detected and taken into account when displaying the second virtual environment. As a result, vertical movements and vertical accelerations of the motor vehicle when displaying the second virtual environment can be taken into account so that the displayed second virtual environment is also varied according to the vertical movements that occur. As a result, it can be ensured in a particularly reliable manner that the wearer of the virtual reality glasses does not experience nausea by displaying the first virtual environment.

In addition, it may also be provided that rotational movements about the longitudinal axis, transverse axis and / or vertical axis of the motor vehicle are also detected and taken into account in the display of the second virtual environment. Preferably, therefore, all possibilities of movement of the motor vehicle are detected, evaluated and taken into account in the display of the second virtual environment. As a result, a particularly realistic representation by means of the second virtual environment can take place such that the actual movement of the motor vehicle and the relative movement of the motor vehicle to the motor vehicle environment can be represented by the second virtual environment in order to increase the occurrence of nausea in the wearer of the virtual reality glasses prevent.

According to a further advantageous embodiment of the invention, it is provided that detected in the direction of travel in front of the motor vehicle lane course or provided or at least displayed as part of the second environment. Thereby, the wearer of the virtual reality glasses is continuously informed about the driving course of the motor vehicle, which in addition can contribute to reducing the risk of nausea generation in the wearer of the virtual reality glasses.

The virtual reality system according to the invention comprises a virtual reality glasses, a detection device for detecting the movement of a motor vehicle and a control device. The control device is designed to control the virtual reality glasses such that a first virtual environment by means of the virtual reality glasses in a first display region of the virtual reality glasses regardless of the detected movement of the motor vehicle and simultaneously a second virtual environment represented by the virtual reality glasses in a second display region of the virtual reality glasses corresponding to the detected movement of the motor vehicle. Advantageous embodiments of the inventive method are to be regarded as advantageous embodiments of the virtual reality system according to the invention, wherein the virtual reality system has in particular means for performing the method steps.

The motor vehicle according to the invention comprises the virtual reality system according to the invention or an advantageous embodiment of the virtual reality system according to the invention.

The virtual reality system 12 includes at least one virtual reality glasses 14 to view virtual content. Furthermore, the virtual reality system points 12 a detection device 16 which is adapted to the movement of the motor vehicle 10 capture. The detection device 16 For example, it may include a variety of sensors, such as speed sensors, acceleration sensors and the like, by means of which both speeds and accelerations of the motor vehicle 10 can be detected in all possible directions of movement. The virtual reality system 12 further comprises a control device 18 for driving the virtual reality glasses 14 , The control device 18 is doing with the detection device 16 so coupled information technology that the control device corresponding signals with respect to the detected movements of the motor vehicle 10 from the detection device 16 receive and then evaluate. The control device 18 is trained to use the virtual reality glasses 14 such that a first virtual environment using the virtual reality glasses 14 in a first display area of the virtual reality glasses 14 regardless of the detected movement of the motor vehicle 10 and simultaneously a second virtual environment using the virtual reality glasses 14 in a second display area of the virtual reality glasses 14 corresponding to the detected movement of the motor vehicle 10 is pictured.

In 2 are a first display area 20 and a second display area 22 the virtual reality glasses 14 shown schematically. The following is a procedure for operating the virtual reality glasses 14 explained in more detail. A vehicle occupant, not shown here, can drive while driving with the motor vehicle 10 the virtual reality glasses 14 Set up to display a variety of media content. So can the the virtual reality glasses 14 carrying vehicle occupant while driving the motor vehicle 10 For example, you can display a movie on a virtual screen, like in a movie theater.

During the operation of the virtual reality glasses 14 is continuously the movement of the motor vehicle 10 by means of the detection device 16 detected. In this case, both longitudinal movements, transverse movements and vertical movements of the motor vehicle 10 detected. Both respective speeds in the longitudinal direction, transverse direction and vertical direction as well as accelerations in the longitudinal direction, transverse direction and vertical direction of the motor vehicle 10 are continuously measured and recorded. In addition, also rotational movements of the motor vehicle 10 be detected and evaluated around the longitudinal axis, transverse axis and vertical axis.

The control device 18 controls the virtual reality glasses 14 such that a first virtual environment 24 using the virtual reality glasses 14 in the first display area 20 the virtual reality glasses 14 regardless of the detected movement of the motor vehicle 10 is pictured. The control device 18 controls the virtual reality glasses 14 in such a way that simultaneously a second virtual environment 26 using the virtual reality glasses 14 in the second display area 22 the virtual reality glasses 14 corresponding to the detected movement of the motor vehicle 10 is pictured. In the present case, the first display area 20 from the second display area 22 surround. There are also essentially any alternative arrangements of the display areas 20 . 22 possible to each other. For example, the display area 22 in the form of respective left and right of the display area 20 arranged beams are selected. The two display areas 20 . 22 can also be arranged side by side, for example. For example, the wearer of virtual reality glasses 14 select or set by means of a corresponding menu, such as the size ratios between the display areas 20 . 22 designed and how the display areas 20 . 22 to be arranged to each other.

For example, as the second virtual environment 26 a corresponding to the detected movement of the motor vehicle 10 moving landscape displayed. Should be the wearer of virtual reality glasses 14 within the first display area 20 watching a movie on a virtual screen, so in the second display area 22 a relative to the first displayed virtual environment 24 moving landscape, the landscape depending on the detected movement of the motor vehicle 10 emotional. Alternatively, it is also possible that, for example by means of a camera system relative to the motor vehicle 10 actually moving vehicle environment detected and as the second virtual environment 22 is shown. Alternatively, it is also possible that the wearer of the virtual reality glasses 14 in the first display area 20 watching a film on the said virtual screen and feeling it hovering over an alienated landscape that moves adequately to the real environment, by this alienated landscape in the second display area 22 in the form of the second virtual environment 26 is shown.
