Description

The invention relates to a method for operating a virtual reality glasses and a system with a virtual reality glasses.

A virtual reality goggle is a particular form of a so-called 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 additionally has sensors for detecting the 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. Since the display follows all the head movements of the wearer through the head posture, he gets the feeling to move directly in an image landscape created by a computer.

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.

For example, a virtual motor vehicle can be displayed by means of such virtual reality glasses. For example, if a wearer of the virtual reality glasses wants to look at the cockpit of the virtual motor vehicle, it is conceivable that the virtual cockpit of the virtual motor vehicle is displayed by means of the virtual reality goggles. Usually, the virtual cockpit can thereby be displayed in dependence on a detected position of the virtual reality glasses from respectively different virtual observation positions by means of the virtual reality glasses. In order to enable a particularly realistic representation and perception of the virtual cockpit, it would u. a. advantageous to additionally display a virtual vehicle environment. This may possibly be associated with an increased computing effort on the part of the virtual reality glasses and / or a control device for driving the virtual reality glasses.

It is the object of the present invention to provide a method for operating a virtual reality glasses and a system with a virtual reality glasses, by means of which a particularly realistic representation of a virtual object and a virtual environment surrounding the virtual object in a simplified manner can be displayed.

This object is achieved by a method for operating a virtual reality glasses and by a system with a virtual reality glasses with the features of the independent 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 goggle, respective virtual observation positions are predefined corresponding to a continuously recorded position of the virtual reality goggles. A virtual object and a vicinity of a virtual environment surrounding the virtual object are thereby displayed from the currently specified virtual observation position. At the same time, a remote area of the virtual environment surrounding the near area is displayed independently of the detected position of the virtual reality goggles from an invariable virtual observation position.

In other words, therefore, the position of the virtual reality glasses in the room is continuously detected, wherein a change in the position of the virtual reality glasses is assigned to a respective changed virtual observation position. Depending on the currently assigned virtual observation position, therefore, the virtual object is displayed from this virtual observation position. A virtual short-range is also displayed from the just given or assigned virtual observation position, which is given as a function of the currently detected position of the virtual reality glasses. A long range of the virtual environment surrounding the near area is always displayed, independent of the detected position of the virtual reality glasses, from the same unchanged virtual viewing position.

Thus, in a near or middle virtual distance range, a computer-generated environment is provided together with the computer-generated virtual object, wherein, depending on the variable head position and thus variable position of the virtual reality glasses, this near or middle distance range is also changed from virtual Observation positions is displayed. The long range surrounding the near range is always displayed from the same invariable virtual observation position. Due to the fact that only the perspective on the virtual object and on the virtual close range is also changed as a function of the changeable head position and the perspective on the far field remains unchanged, the computational effort and thus also the requirements for Hardware components, such as the virtual reality glasses, control devices and the like, are significantly reduced, while still a particularly high immersion, so a particularly realistic representation by means of the virtual reality glasses can be achieved.

An advantageous embodiment of the invention provides that the near area extends from the virtual object to a first virtual distance, in particular from 10 m to 15 m, the far range extending from the near area to a second virtual distance which is larger than the first virtual distance is. In other words, the proximity of the virtual environment directly surrounds the virtual object, with the far-end being directly connected to and surrounding the proximity area. For example, the virtual object, the near zone and the far zone can be arranged concentrically. In the vicinity of preferably 10 m to 15 m distance to the virtual object, a wearer of the virtual reality glasses will perceive a change in perspective to corresponding parts of the vicinity. To more distant parts, ie to parts that belong to the far field, a wearer of the virtual reality glasses will not be able to detect any changes in his head position. By adjusting only the perspective of the virtual object and the near field depending on the detected head position, the computational effort when generating the display of the virtual reality glasses can be significantly reduced. As a result, a particularly smooth presentation can be ensured with a simultaneously very realistic presentation.

In a further advantageous embodiment of the invention, it is provided that a virtual vehicle interior, in particular a virtual cockpit, and the virtual environment a virtual vehicle environment are displayed as the virtual object. For example, this can be particularly advantageous for car dealerships because they no longer have to hold a large number of differently configured vehicles. Instead, it is possible for potential buyers to configure their desired motor vehicles, in particular the vehicle interior, and display them by means of the virtual reality glasses. The fact that a virtual vehicle environment is displayed as the virtual environment allows a particularly realistic virtual assessment of the respectively configured vehicle variant, in particular of the vehicle interior.

According to a further advantageous embodiment of the invention, it is provided that by means of a stereo camera system an at least partially all-round recording of a real vehicle is recorded and converted into the virtual vehicle environment. The fact that the at least partially all-round recording is recorded by means of a stereo camera system, the virtual vehicle environment using the virtual reality glasses can be displayed quasi-three-dimensional, by means of the virtual reality glasses for a respective right and left eye of a wearer of the virtual reality -Glasses slightly altered, recorded contents of the at least partial surround recording are displayed, as a result, sets up a three-dimensional effect. The at least partial all-round recording can be, for example, a 180 ° recording up to a 360 ° round recording. The wearer of the virtual reality glasses can thus see through pivoting of his head a part or even substantially the entire virtual vehicle environment, while the wearer of the virtual reality glasses virtually resides within the vehicle interior. Preferably, the at least partially all-round recording can be recorded during the journey of the real vehicle. As a result, it is also possible to simulate a virtual journey with the virtual motor vehicle, while the wearer of the virtual reality goggles can just display the virtual vehicle interior. Thus, the real vehicle environment is converted to the virtual vehicle environment, with the virtual vehicle environment passing by the wearer of the virtual reality goggles while it is virtually in the vehicle interior. As the head position is changed, the virtual perspective on the proximity of the virtual vehicle environment is also changed accordingly, leaving the virtual perspective unchanged on the far end of the virtual vehicle environment. This also contributes to be able to provide a particularly realistic representation with at the same time very little computational effort.

In a further advantageous embodiment of the invention, it is provided that parts of the near area and the far area are displayed concealed in dependence on the currently predetermined virtual observation position of parts of the virtual object. In other words, a kind of virtual parallax effect is achieved by concealed, depending on the head position, and thus depending on the position of the virtual reality glasses, different parts of the near and far range depending on the currently given virtual observation position of parts of the virtual object become. This allows a particularly realistic representation of the virtual object and surrounding surrounding area.

The system according to the invention comprises a virtual reality glasses and a detection device, which is designed to continuously the position to capture the virtual reality glasses and assign the respective virtual observation position. The system according to the invention further comprises a control device, which is designed to control the virtual reality glasses in such a way that a virtual object as well as a surrounding area of a virtual environment surrounding the virtual object from the currently given virtual observation position and a remote area of the virtual environment surrounding the near area is displayed from an invariable virtual observation position independently of the detected position of the virtual reality glasses. Advantageous embodiments of the method according to the invention are to be regarded as advantageous embodiments of the system according to the invention, wherein the system has in particular means for carrying out the method steps.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

The drawing shows in:

1 a schematic representation of a system having a virtual reality glasses, a detection device and a control device for driving the virtual reality glasses;

2 a perspective view of a support of the virtual reality glasses;

3 a perspective view of a displayed by the virtual reality glasses virtual vehicle interior of a virtual motor vehicle; and in

4 a schematic representation of a plan view of the arrangement of the virtual motor vehicle, wherein the virtual motor vehicle is surrounded by a near area and an adjoining remote area of a virtual vehicle environment.

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

A system 10 with a virtual reality glasses 12 , a detection device 14 and a control device 16 for driving the virtual reality glasses 12 is in a schematic representation in 1 shown. The detection device 14 is trained to continuously the position of the virtual reality glasses 12 to capture and assign to each virtual observation positions. The detection device 14 For example, it may have a camera system by which the position of the virtual reality glasses 12 can be detected and assigned to respective virtual observation positions.

In 2 is a carrier 18 the virtual reality glasses 12 shown schematically. At the carrier 18 the virtual reality glasses 12 For example, it could be a potential car buyer who owns the virtual reality glasses 12 has set up to virtually display a just-configured desired motor vehicle.

In 3 is a virtual vehicle interior 20 shown in detail, which by means of virtual reality glasses 12 is shown. By means of the detection device 14 is continuously the position of the virtual reality glasses 12 recorded and assigned to respective virtual observation positions. Moves the carrier 18 his head, for example, to the right, this is done by means of the detection device 14 detected and the position change accordingly takes into account that the virtual observation position from which the vehicle interior 20 using the virtual reality glasses 12 is displayed, is changed accordingly. Should the carrier 18 so move his head to the right, he virtually no longer sits in front of the steering wheel 22 Instead, for example, frontally in front of the virtual center console 24 , This could be useful, for example, if the carrier 18 the virtual reality glasses 12 For example, a virtual display 26 or a virtual climate control panel 28 of the displayed virtual vehicle interior 20 would like to take a closer look.

The control device 16 of the system 10 is therefore designed to be the virtual reality glasses 12 such that by means of the virtual reality glasses 12 a virtual object, in the present case, the virtual vehicle interior 20 , from the just by means of the detection device 14 currently specified virtual observation position is displayed.

To a particularly realistic presentation and perception of the virtual vehicle interior 20 to achieve which by means of the virtual reality glasses 12 is displayed, in addition, a virtual vehicle environment 30 also using the virtual reality glasses 12 displayed. The carrier 18 looks through the virtual reality glasses 12 not just the vehicle interior 20 , but also the vehicle environment 30 by, for example, virtual through the unspecified virtual windshield of the motor vehicle looks.

In 4 are a schematic representation of a virtual motor vehicle 34 , a close range 36 the virtual vehicle environment 30 and a long distance area 38 the virtual vehicle environment 30 shown schematically. In the 4 shown schematic representation of the carrier sees 18 the virtual reality glasses 12 not, instead, this schematic representation is only to illustrate the subsequent steps in operating the virtual reality glasses 12 ,

As already explained, when operating the virtual reality glasses 12 continuously the position of the virtual reality glasses 12 by means of the detection device 14 detected. Corresponding to the continuously recorded position of the virtual reality glasses 12 respective virtual observation positions are given. A first recorded real position of the virtual reality glasses 12 Thus, a corresponding first virtual observation position is assigned to a second acquired real position of the virtual reality glasses 12 So a second virtual observation position is assigned, etc.

The vehicle interior 20 and the close range 36 the vehicle environment 30 are displayed from the currently specified virtual observation position. Changed the carrier 18 so his head position in translational direction, so also changes the virtual observation position, from which by means of the virtual reality glasses 12 the vehicle interior 20 and the close range 36 are displayed. The the close range 36 surrounding long-range area 38 the virtual vehicle environment 30 However, regardless of the captured position of the virtual reality glasses 12 displayed from a fixed virtual observation position. In other words, this causes a change in the head position of the wearer 18 and thus a change in the position of the virtual reality glasses 12 only that perspective on the virtual vehicle interior 20 and the near area 36 the virtual vehicle environment 30 is changed. Even with a change in the head position of the wearer 18 and thus a change in the position of the virtual reality glasses 12 However, the presentation of the long-range does not change 38 the virtual vehicle environment 30 using the virtual reality glasses 12 ,

The close range 36 extends from the virtual object 34 up to a first virtual distance, whereby the far range 38 from the first virtual environment 36 extends to a second virtual distance that is greater than the first virtual distance. For example, the close range may be 36 to a virtual distance of 10 m to 15 m from the virtual motor vehicle 34 extend, with the far range 38 according to the motor vehicle 34 away to the near area 36 followed.

To the near range 36 and the distant area 38 the virtual vehicle environment 30 using the virtual reality glasses 12 to be able to display at all, corresponding image or video material must first be provided. For example, it is possible that by means of a stereo camera system, not shown here recorded at least partially all-round recording of a real vehicle and in the vicinity 36 and the distant area 38 comprehensive virtual vehicle environment 30 is converted. In this case, for example, a 180 ° comprehensive partial surround recording or even a 360 ° comprehensive all-round recording of a real vehicle recorded and in the virtual vehicle environment 30 being transformed. The at least partially all-round recording can be recorded, for example, during the journey of the real vehicle.

For example, it is possible for the user 18 during a virtual journey with the motor vehicle 34 the vehicle interior 20 using the virtual reality glasses 12 want to show. In this case, both the near range pull 36 as well as the distant area 38 virtually on the carrier 18 the virtual reality glasses 12 past. This results in a particularly realistic representation and perception of the virtual vehicle interior 20 , A translatory head movement of the wearer 18 and thus a translational movement of the virtual reality glasses 12 causes in turn that the virtual observation position changed and according to the changed virtual observation position both the vehicle interior 20 as well as the close range 36 be displayed changed. A change in the head position and thus a change in the position of the virtual reality glasses 12 However, does not change the presentation or display of the long-range 38 , While regarding the virtual vehicle interior 20 and the neighborhood 36 a full three-dimensional impression with the wearer 18 would arise in the distant long-range 38 a virtual perspective change hardly come to fruition as the wearer 18 this would not perceive.

The virtual vehicle environment 30 So it only has to be related to the near range 36 in accordance with a detected change in the head position of the wearer 18 and thus a detected change in the position of the virtual reality glasses 12 recalculated and adjusted. A recalculation or adaptation of the long range 38 can be omitted. As a result, nevertheless, a very realistic representation and perception of the vehicle interior 20 and the virtual vehicle environment 30 be made possible at the same time significantly reduced computational effort.
