Description

Technical Field

[0001] The invention relates to a method for operating electronic data glasses in a motor vehicle. In addition, the invention also relates to electronic data glasses for displaying content. Background Art

[0002] The use of electronic data glasses, such as augmented reality glasses or also virtual reality glasses, in motor vehicles is known per se. Thus, with the aid of such electronic data glasses, it is possible, for example, for vehicle occupants to watch movies, play computer games or to display additional information about real objects in their surroundings.

[0003] When a vehicle occupant uses such electronic data glasses during driving, the following situation may occur: motion sickness or so-called simulator sickness occurs in the vehicle occupant. Motion sickness is also called travel sickness or motion sickness. Symptoms can include physical reactions such as pallor, dizziness, headache, nausea and vomiting. According to mainstream opinion, motion sickness occurs when the sensory organs provide contradictory information about the spatial position and movement of the body. This can occur when using electronic data glasses in a motor vehicle. Depending on the content that the electronic data glasses are displaying, the eyes of the wearer of the electronic data glasses can provide sensory impressions that contradict the sensory impressions of the balance organs, because the motor vehicle may be moving forward in a different way than the wearer of the electronic data glasses visually perceives through the displayed content.

[0004] Document DE 20 2014 005 329 U1 deals with the problem that when wearing electronic data glasses, vehicle occupants may sometimes feel nauseous. It is proposed to use a contactless, optical or acoustic receiver to detect the position of the data glasses and track the movement of the data glasses, which works together with an automatic adjustment or control system of the data glasses.

[0005] Document DE 10 2014 221 608 A1 describes a method for deactivating the display of a contact simulation on data glasses as a function of the movement of a vehicle. As long as the vehicle movement exceeds a threshold value, the display of the contact simulation on the data glasses is interrupted.

[0006] Document DE 10 2014 015 871 A1 describes a display system for a vehicle, wherein the display system includes virtual reality glasses. Provision is made here that a detection device already present in the vehicle and designed for detecting the position and posture of the vehicle occupants is additionally used to also detect the position of the virtual reality glasses inside the vehicle. Summary of the invention

[0007] The object of the present invention is to provide a solution by means of which motion sickness can be prevented in a reliable and simple manner for vehicle occupants who wear electronic data glasses.

[0008] This object is achieved by a method for operating electronic data glasses in a motor vehicle and by electronic data glasses having the features described below.

[0009] In the method according to the invention for operating electronic data glasses in a motor vehicle, content is displayed by means of electronic data glasses that have been worn by a vehicle occupant. The electronic data glasses have a satellite-based / satellite-supported detection device, by means of which the position of the motor vehicle is continuously detected. The movement of the motor vehicle is detected based on the continuously detected position of the motor vehicle. In order to prevent motion sickness of the vehicle occupant, the content displayed by means of the electronic data glasses is adapted to the determined movement of the motor vehicle.

[0010] The satellite-based detection device of the electronic data glasses can be, for example, a GPS sensor. However, other sensors are also possible, by means of which satellite-based position detection of the motor vehicle and therefore also of the electronic data glasses can be achieved. In the method according to the invention, the position of the motor vehicle and therefore also the movement of the motor vehicle can be determined continuously in a simple manner solely by means of the electronic data glasses. Thus, motion sickness can be prevented for a vehicle occupant who has put on the electronic data glasses by adapting the content displayed by means of the electronic data glasses to the determined movement of the motor vehicle.

[0011] Data representing the absolute movement of the motor vehicle and therefore of the electronic data glasses are therefore always available in the electronic data glasses. The invention is based on the recognition that if people in the vehicle want to use virtual reality or augmented reality content, in particular, and if they do not suffer from motion sickness or simulator sickness, it is necessary to partially or completely coordinate the content displayed by means of the electronic data glasses with the absolute movement of the wearer of the electronic data glasses.

[0012] In the method according to the invention, the absolute movement of the vehicle occupant is reliably determined in that a satellite-based detection device installed in the electronic data glasses continuously detects the position of the motor vehicle. With knowledge of the position of the motor vehicle or of continuous changes in the position of the motor vehicle, the movement of the motor vehicle can be continuously determined during the display of the content by the electronic data glasses. Motion sickness of the vehicle occupant can be reliably prevented by partially or completely coordinating the content displayed by the electronic data glasses with the movement of the motor vehicle. Thus, the method according to the invention can ensure that no contradictory sensory impressions occur in the vehicle occupant in the event that the perceived movement of the motor vehicle and the perceived display content do not correspond.

[0013] An advantageous embodiment of the invention provides that the electronic data glasses have a sensor device, by means of which the movement of the data glasses is detected, wherein, in order to prevent motion sickness of the vehicle occupants, the content displayed by means of the electronic data glasses is additionally adapted to the detected movement of the data glasses. The sensor device can be, for example, an acceleration sensor. However, other sensors are also possible as long as reliable movement detection of the data glasses can be achieved. Thus, the data glasses can detect their own movement by means of the sensor device installed therein. In order to prevent motion sickness of the vehicle occupants, the content displayed by means of the electronic data glasses is additionally adapted to the detected movement of the data glasses. In addition to the pure vehicle movement, the head movement of the wearer of the electronic data glasses can therefore also be detected and taken into account when operating the data glasses to display the content. Therefore, it is possible to distinguish the contradictory optical sensory impressions and balance organ sensory impressions of the wearer of the electronic data glasses in a particularly reliable manner in order to prevent motion sickness. In this case, the electronic data glasses can also generate or collect all the data required for preventing motion sickness individually.

[0014] Another advantageous embodiment of the invention provides that the position of the motor vehicle is continuously detected by means of a mobile device arranged in the motor vehicle and having a satellite-based detection device, and based on the position of the motor vehicle, the movement of the motor vehicle is also determined, and in order to prevent motion sickness of the vehicle occupants, the content displayed by means of the electronic data glasses is adapted to the movement of the motor vehicle determined by means of the mobile device. Preferably, the mobile device is a smartphone, which preferably transmits data characterizing the determined movement of the motor vehicle to the electronic data glasses in a wireless manner. Therefore, it is also possible to continuously determine the position of the motor vehicle and thus the movement of the motor vehicle by means of the mobile device, so as to prevent motion sickness by correspondingly controlling the data glasses. In particular, when the mobile device is a smartphone, the smartphone is usually carried by the vehicle occupants anyway. Therefore, it is also possible, for example, to adjust the data provided about the movement of the vehicle or the change in the position of the vehicle by the mobile device and the electronic data glasses. In this way, particularly accurate movement data of the vehicle can be generated. If, for example, the satellite-based detection device of the electronic data glasses fails once, the mobile device can still provide data for the movement detection of the motor vehicle as before.

[0015] In another advantageous embodiment of the present invention, it is provided that data characterizing the movement of the motor vehicle are transmitted to electronic data glasses by means of the motor vehicle, and the electronic data glasses adapt the displayed content to the determined movement of the motor vehicle in order to prevent motion sickness of the vehicle occupants. For this purpose, the motor vehicle can, for example, have a wireless or wired interface, through which the above-mentioned data characterizing the movement of the motor vehicle can be transmitted to the electronic data glasses. Therefore, particularly accurate movement data of the motor vehicle can be provided, because the data characterizing the movement of the motor vehicle is provided by the motor vehicle itself. In modern motor vehicles, a plurality of sensors are usually installed, by means of which acceleration and speed are continuously detected. These data can be provided, for example, via a bus system when the interface of the electronic data glasses is connected. Therefore, motion sickness can be prevented in a particularly reliable manner.

[0016] The electronic data glasses according to the invention for displaying content comprise a satellite-based detection device for continuously detecting the position of a motor vehicle, wherein the electronic data glasses are configured to determine the movement of the motor vehicle based on the continuously detected position of the motor vehicle and to adapt the displayed content to the determined movement of the motor vehicle in order to prevent motion sickness for a vehicle occupant wearing the electronic data glasses. Advantageous embodiments of the method according to the invention are to be regarded as advantageous embodiments of the electronic data glasses according to the invention and vice versa, wherein the electronic data glasses in particular have means for carrying out the method steps.

[0017] An advantageous embodiment of the electronic data glasses provides that the satellite-based detection device is a GPS sensor. However, other sensors for satellite-based position detection can also be installed in the electronic data glasses.

[0018] The electronic data glasses are preferably virtual reality glasses or augmented reality glasses. In addition, the electronic data glasses can also be mixed reality glasses.

[0019] Further advantages, features and details of the invention are apparent from the following description of preferred embodiments and from the accompanying drawings. The features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the description of the drawings and / or shown individually in the drawings can be used not only in the respectively indicated combination but also in other combinations or individually without departing from the scope of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 A schematic diagram of a motor vehicle is shown, in which a vehicle occupant is seated, the vehicle occupant having put on electronic data glasses. DETAILED DESCRIPTION

[0021] exist Figure 1, a motor vehicle 1 is shown in a very schematic illustration. A vehicle occupant 2 is sitting in the motor vehicle 1, the vehicle occupant having put on electronic data glasses 3. The electronic data glasses 3 can be, for example, virtual reality glasses or also augmented reality glasses. The electronic data glasses 3 are used to display a variety of different contents and comprise a satellite-based detection device 4 for continuously detecting the position of the motor vehicle 1. The electronic data glasses 3 are designed to determine the movement of the motor vehicle 1 based on the continuously detected position of the motor vehicle 1 and, in order to prevent motion sickness of the vehicle occupant 2, to adapt the contents displayed by means of the electronic data glasses 3 to the determined movement of the motor vehicle 1.

[0022] If, for example, a movie is displayed by means of electronic data glasses 3 while the motor vehicle 1 is in motion, it can be provided that, for example, symbols or other movements corresponding to the detected movement of the motor vehicle 1 are displayed in the edge region. The movie can then be displayed in the central and preferably larger display region.

[0023] For example, a computer game played by the vehicle occupant 2 while the motor vehicle 1 is traveling can also be displayed with the aid of the electronic data glasses 3. In this case, it can be provided, for example, that the virtual movements of the vehicle occupant 2 within the displayed computer game correspond to the detected movements of the motor vehicle 1. This ensures that no contradictory sensory impressions are produced in the vehicle occupant 2. This is because the movement actually perceived by the vehicle occupant 2 based on the forward movement of the motor vehicle 1 and the visual perception of the displayed content with the aid of the electronic data glasses 3 thus at least substantially correspond.

[0024] The content displayed by means of the electronic data glasses 3 is thus partially or completely coordinated with the detected movement of the motor vehicle 1. As a result, so-called simulator sickness or motion sickness of the vehicle occupant 2 can be prevented or at least significantly reduced.

[0025] Furthermore, the electronic data glasses 3 include a sensor device 5, by means of which the movements of the data glasses 3 are detected. In order to prevent motion sickness of the vehicle occupant 2, the content displayed by means of the electronic data glasses 3 is additionally adapted to the detected movements of the data glasses 3. The sensor device 5 can be, for example, one or more acceleration sensors, by means of which the movements of the data glasses 3 can be continuously detected.

[0026] Furthermore, a mobile device 6 in the form of a smartphone is arranged in the motor vehicle 1, which has a satellite-based detection device 7. The position of the motor vehicle 1 is continuously detected by means of the satellite-based detection device 7 and the movement of the motor vehicle 1 is also determined based on the position of the motor vehicle. In order to prevent motion sickness of the vehicle occupant 2, the content displayed by means of the electronic data glasses 3 is adapted to the movement of the motor vehicle 1 determined by means of the mobile device 6. It is thus possible in a redundant manner to detect changes in position and movements of the motor vehicle 1 not only by means of the electronic data glasses 3 but also by means of the mobile device 6 in order to prevent motion sickness of the vehicle occupant 2 in the manner already described. If one of the satellite-based detection devices 4, 7 fails, it can furthermore be reliably ensured that changes in position and therefore movements of the motor vehicle 1 can continue to be detected, so that the electronic data glasses 3 can be controlled accordingly to prevent motion sickness when the data are known.

[0027] Furthermore, it is also possible to transmit data characterizing the movement of the motor vehicle 1 to the electronic data glasses 3 by means of the motor vehicle 1 itself, which adapt the displayed content to the determined movement of the motor vehicle in order to prevent motion sickness of the vehicle occupant 2. For this purpose, the motor vehicle 1 can have an interface 8, which is only schematically indicated here, which is provided for transmitting data characterizing the movement of the motor vehicle 1 to the electronic data glasses 3, preferably wirelessly. For this purpose, the motor vehicle 1 preferably has a plurality of sensors, by means of which the acceleration and speed of the motor vehicle 1 can be detected. These sensors can be connected to the interface 8, for example, via a data bus, in order to transmit data characterizing the movement of the motor vehicle 1 to the electronic data glasses 3. The motor vehicle 1 itself can provide the movement data in a particularly precise manner, so that when using these data, motion sickness of the vehicle occupant 2 can be prevented in a particularly reliable manner.
