Description

TECHNICAL FIELD

[0001] The present invention relates to a method and a device for preventing motion sickness when viewing image content displayed on a screen in a moving vehicle. The technical solution relating to a computer program is also subject of the invention. BACKGROUND

[0002] When using various means of transportation, such as a car, a bus, a ship or an airplane, motion sickness, also called kinetosis, can occur. Motion sickness can arise due to differences between various sensory organs, for example by differences between the sense of balance and the visual perception. When a person, for example in a car ride, is intensively reading a book or is concentrating on a screen, the person feels the inclination of the car, but there is no change in the visual perception.

[0003] In order to prevent motion sickness, it is possible to manipulate the driving style or the driving trajectory of a highly automated vehicle such that the driving style or the driving trajectory incurs as little motion sickness phenomenon as possible at the vehicle occupants. DE 10 2017 208 583 A1 describes such a solution.

[0004] Furthermore, it is possible to simulate a background motion effect on the screen of, for example, a smartphone when in use. Here, when the phone is rotated, the background moves slightly relative to the illustration in the foreground. This creates a 3D effect. SUMMARY

[0005] Against this background, with the solution presented here, a method is presented according to the invention for preventing motion sickness when viewing image content displayed on a screen in a moving vehicle, in particular a highly automated vehicle; furthermore a device using the method is presented; and finally a corresponding computer program is presented. With the preferred measures of the invention, advantageous extensions and improvements of the described device are possible.

[0006] The solution presented here makes it possible to determine, on the basis of parameters from the trajectory planning in a highly automated vehicle, a specific motion of an image plane, for example a background, of an image shown on a mobile screen or on a screen fixedly installed in the vehicle, in order to prevent motion sickness at the vehicle occupants by means of the image motion, for example the movement of the background of the image. Advantageously, using the data for the trajectory planning, it is possible to determine the specific image motion for avoiding the motion sickness phenomenon already in the preparation phase, whereby a time delay between the perception of the vehicle motion and the image motion can be avoided. Furthermore, the method presented here can be used in particular in combination with the screen of a mobile device, which makes it possible for the user to advantageously apply the motion sickness avoidance in various vehicles or means of transportation.

[0007] A method is introduced for preventing motion sickness when viewing image content displayed on a screen in a vehicle under travel, in particular in a highly automated vehicle under travel. The method comprises at least the steps of reading a trajectory planning signal and a display signal, and determining an image motion signal. The trajectory planning signal read in the step of reading represents a planned trajectory of the vehicle and comprises information about acceleration maneuvers, braking maneuvers and cornering maneuvers along the planned route, and / or comprises information about planned controls of the vehicle under travel. The display signal read in the step of reading represents at least one application displayed on a screen. In the step of determining, the image motion signal is determined for moving background image content of at least one application displayed on a screen as presented against the displayed image content with respect to the displayed image content using the trajectory planning signal and the display signal. The movement of the presented background image content with respect to the displayed image content is made here in order to prevent motion sickness when viewing image content displayed on a screen in a vehicle under travel. In the step of reading, a user signal is additionally read, wherein the user signal represents a user-specific movement intensity, wherein in the step of determining the image motion signal is additionally determined using the user signal.

[0008] The vehicle can be an autonomously traveling vehicle, for example a car, a bus or a train. The trajectory planning signal can be provided, for example, by a control unit of the vehicle for making a trajectory planning. The trajectory planning signal can comprise, for example, information about planned lateral and longitudinal accelerations, information about a travel speed at a corner and specific route information such as a slope in the course of the road. With the display signal, the number and the specification of the applications currently presented on the screen can be read. The step of reading can be made continuously or intermittently. The image content presented on the screen can be, for example, images in motion or moving images (Bewegtbild) of a film, or mainly stationary graphics, for example texts of a text messaging program or overview graphics.

[0009] According to an implementation form, in the step of reading, a motion sickness parameter can be determined using the trajectory planning signal. The motion sickness parameter can represent a physical variable of the planned trajectory that is relevant for motion sickness. Then, additionally, the image motion signal can be determined using the motion sickness parameter. The physical variable relevant for motion sickness can be, for example, a tilt of the vehicle, or a lateral or longitudinal acceleration to be expected by the vehicle, or a route feature, such as a particularly narrow corner or a plurality of corners following closely on one another, or any combination of the mentioned variables. Advantageously, the movement of the presented background image content can thus be determined in a preparation phase in dependence on the parameters relevant for motion sickness in order to avoid motion sickness symptoms.

[0010] In the step of determining the image motion signal, according to an embodiment the direction of movement of the background image content can be determined. Additionally or alternatively, the path of movement of the background image content can be determined. This advantageously makes it possible to determine a targeted movement of the background image content, for example depending on the current orientation or inclination of the vehicle. This is advantageous in order to provide the viewer of the image content presented on the screen with information about the orientation and inclination of the vehicle relative to the visually fixed point (the displayed image content) by means of the movement as an expression, in order to minimize motion sickness.

[0011] Furthermore, in the step of reading, the read display signal can comprise a plane parameter according to an embodiment. The plane parameter can represent the number of movable display planes of at least one application displayed on the screen. Depending on the application, it can be possible for the displayed image content to be moved in a plurality of planes, for example when the application displays an intermediate plane between the foreground and the background. In the step of determining, the image motion signal can then be determined using the plane parameter in order to move at least one display plane of at least one application displayed on the screen relative to the displayed image content between the background image content and the image content. Advantageously, it is thereby possible to reduce the discrepancy between the driving motion and the visual perception.

[0012] Additionally, in the step of reading, a user signal can be read according to an embodiment. The user signal can represent a user-specific movement intensity. In the step of determining, the image motion signal can then additionally be determined using the user signal. Advantageously, it is thereby possible to change the movement of the background image content depending on the individual needs of the user (viewer of the screen), for example depending on the susceptibility to motion sickness, or only after a determined driving duration or time interval of viewing the image content displayed on the screen, for example by means of a boundary value for the time interval of the continuously activated screen illumination, to change the movement of the background image content.

[0013] In the step of reading, a seat position signal can additionally be read according to an embodiment. The seat position signal can represent the orientation of the seat position of the viewer of the screen with respect to the driving direction of the vehicle. In the step of determining, the image motion signal can additionally be determined using the seat position signal. For example, the seat position signal can have information about whether the viewer of the screen is sitting with the seat position facing the driving direction of the vehicle or facing against the driving direction. This is advantageous in order to change the movement depending on the seat position of the viewer, for example additionally using the user signal, in order to intensify the movement of the background image content in the case of a situation in which the susceptibility to motion sickness is increased when driving with the seat position facing against the driving direction.

[0014] Furthermore, in the step of reading, according to an embodiment additionally an orientation signal can be read. The orientation signal can represent an orientation as image format of the narrow format or the landscape format of the image content displayed on the screen. In the step of determining, additionally the image motion signal can be determined in the case of using the orientation signal. Advantageously, it is thereby possible to determine the movement, for example the movement direction, of the background image content depending on whether the image content is displayed in the narrow format or in the landscape format. This is particularly advantageous when using the method in connection with a screen of a portable device, for example a smartphone.

[0015] Furthermore, the method can comprise, according to an embodiment, a step of providing an image motion signal. The image motion signal can be provided to an interface to a screen. The screen can be fixedly installed in a vehicle and thereby be part of the vehicle. The screen can also be a component of a mobile device, for example a display of a smartphone or a Tablet-Computer. The step of providing can be implemented in order to manipulate a movement of background image content of at least one application displayed on the screen relative to the displayed image content as background to the displayed image content.

[0016] The method can be implemented, for example, in software or hardware, or in a hybrid form of software and hardware, for example in a control device or a device.

[0017] Furthermore, the approach presented here proposes a device which is configured in order to carry out, manipulate or implement the steps of a variant of the method presented here in a corresponding apparatus. For example, a device for preventing motion sickness when viewing image content displayed on a screen in a vehicle driving according to the present application comprises a reading device for reading a trajectory planning signal, a display signal and a user signal, wherein the trajectory planning signal represents a planned trajectory of the vehicle and comprises information about acceleration maneuvers, braking maneuvers and cornering maneuvers along the planned route and / or comprises information about a planned control of the vehicle driving, wherein the display signal represents at least one application displayed on the screen, and wherein the user signal represents a user-specific movement intensity, and a determining device for determining an image motion signal in the case of using the trajectory planning signal, the display signal and the user signal, the image motion signal for moving background image content of the at least one application displayed on the screen relative to the displayed image content as background to the displayed image content in order to prevent motion sickness when viewing the image content displayed on the screen in the vehicle driving. Through the implementation variant in the form of the device of the present application, the task on which the present application is based can also be solved quickly and efficiently.

[0018] Therefore, the device may include: at least one computing unit for processing signals or data, at least one storage unit for storing signals or data, at least one interface to a sensor or actuator, and / or at least one communication interface, wherein the at least one interface to the sensor or actuator is used to read sensor signals from the sensor or to output data signals or control signals to the actuator, and the at least one communication interface is used to read or output data, all of which are embedded in a communication protocol. The computing unit may be, for example, a signal processor, a microcontroller, or the like, and the storage unit may be a flash memory, EEPROM, or magnetic storage unit. The communication interface may be configured to read or output data wirelessly and / or via wired means, wherein the communication interface capable of reading or outputting wired data may, for example, read the data from a corresponding data transmission line electrically or optically, or output the data to a corresponding data transmission line.

[0019] In this invention, the device can be understood as an electrical device that processes sensor signals and outputs control signals and / or data signals accordingly. The device may have an interface that can be constructed in hardware and / or software. In a hardware-based construction, the interface may, for example, be a portion of a so-called system ASIC containing very different functions of the device. However, it is also possible that the interface is its own integrated circuit, or at least partially comprises discrete components. In a software-based construction, the interface may be, for example, a software module existing alongside a separate software module on a microcontroller.

[0020] It is also advantageous to have a computer program product or computer program with program code, which can be stored on a machine-readable carrier or storage medium such as semiconductor memory, hard disk memory or optical memory, and the program code is used to: perform, implement and / or manipulate the steps of the method according to one of the embodiments described above, especially when the program product or program is implemented on a computer or device.

[0027] Figure 1 A schematic view of a vehicle 100 having a device 105 for preventing motion sickness when viewing image content displayed on a screen 110 in a vehicle 100 under travel, in particular a highly automated vehicle 100 under travel, according to an embodiment is shown. The vehicle 100 is here exemplarily shown as a motor vehicle in the shape of a passenger car or the like, and has, in addition to the device 105 and the screen 110, a trajectory planning control unit 120.

[0028] The device 105 comprises a reading means 125 and a determining means 130. The reading means 125 is configured to read a trajectory planning signal 135 from the trajectory planning control unit 120 and a display signal 140 from the screen 110. The trajectory planning signal 135 is indicative of a planned trajectory of the vehicle 100. The display signal 140 is indicative of at least one application displayed on the screen 110, e.g. a detailed description of the application, a display duration of the application on the screen 110 or a number of applications displayed on the screen 110. The determining means 130 is configured to determine, using the trajectory planning signal 135 and the display signal 140, an image motion signal 145 for moving a background image content 150 of at least one application displayed on the screen 110 as presented against a displayed image content 115 relative to the displayed image content 115. The image motion signal 145 is determined in order to prevent motion sickness when viewing the image content 115 displayed on the screen 110 in the vehicle 100 under travel.

[0029] The device 105 is connected or connectable to the screen 110 in a signal-transmittable manner, for example via a radio connection. Furthermore, the device 105 is connected or connectable to the trajectory planning control unit 120 and optionally to at least one sensor arrangement of the vehicle 100 in a signal-transmittable manner. The trajectory planning signals 135 and the display signals 140 are read continuously or intermittently. The trajectory planning signals 135 comprise, for example, information about acceleration maneuvers, braking maneuvers and Abbiege maneuvers along the planned route, and information about the planned control of the highly automated vehicle 100, for example for steering. The determined image motion signals 145 comprise, for example, information about the frequency or repetition rate of the movement of the background image content 150 relative to the displayed image content 115.

[0030] Motion sickness involves about one tenth to one fifth of the population and occurs when using a vehicle, for example a car, such as the vehicle 100 shown here, or when using a boat or an airplane, due to differences between the various sensory organs, such as between the sense of balance and the visual perception, for example when reading a book or focusing on the screen 110, a feeling of the car tilting without a visual change occurs. The symptoms of motion sickness are different, but most are manifested by an increased feeling of nausea. The relevance of anti-motion sickness measures increases when riding in a vehicle 100 that drives with high automation, especially when the driver no longer actively focuses on the driving task, but does side activities that potentially trigger or promote motion sickness, because even if the visual focus is another, for example a book or the screen 110, the visual motion information is processed subconsciously together. Focusing on reading or working on the screen of a smartphone, tablet computer, E-Book-Reader or laptop during a ride in the vehicle 100 increases the occurrence of motion sickness. When such an electronic display medium is rotated, it is possible to simulate a background motion effect. Here, if the electronic display medium, for example a cell phone, is rotated, the background moves slightly relative to the illustration in the foreground. This creates a 3D effect. The device obtains information about the rotation via the built-in gyroscopic sensors or rotation speed sensors. With the solution presented here, the background motion effect, that is to say the movement of the background image content 150 displayed as a background to the displayed image content 115, relative to the displayed image content 115, is used as an anti-motion sickness measure when looking at the screen 110 in a vehicle driving using the trajectory planning data read with the aid of the trajectory planning signal 135. By using the trajectory planning data, it is advantageously possible to prevent motion sickness, because parameters such as lateral acceleration or longitudinal acceleration are known in the preparation phase, for example a few milliseconds to a few seconds before, and are used in order to determine the image motion signal 145 for moving the background image content 150 presented as a background to the displayed image content 115 relative to the displayed image content 115 with the aim of reducing motion sickness.

[0031] Furthermore, the determination device 130 is configured according to an embodiment to determine, for determining the image motion signal 145, a direction of movement of the background image content 150 and additionally or alternatively a movement path of the background image content 150.

[0032] Furthermore, the determining device 130 is configured to determine, according to an embodiment, a motion sickness parameter using the trajectory planning signal 135. The motion sickness parameter represents a physical variable of the planned trajectory which is relevant for motion sickness. In this case, the determining device 130 is also configured to determine the image motion signal 145 using the determined motion sickness parameter. If the autonomous vehicle 100 is driving at a turn, all control parameters of the vehicle 100 are calculated in the preparation phase using the trajectory planning control unit 120. This is possible because the turn and its inclination are known via detailed map information and are measured precisely via on-board sensors, for example by means of radar or lidar. As a result, parameters such as speed at the turn, occurring lateral acceleration, etc. are known in the preparation phase. These information, in particular the expected longitudinal and lateral acceleration, can be transmitted to the electronic device in the vehicle 100 by means of a wireless radio connection, for example Bluetooth. In the embodiment shown here, these information are transmitted to the device 105 by means of the trajectory planning signal 135. These information are used in order to determine the image motion signal 145 with the aim of minimizing the motion sickness effect. The viewer of the screen 110 thus obtains visual information about the current position and inclination of the vehicle 100 relative to the visual fixation point (background). This is comparable to the case when a vehicle occupant looks out of the window and sees the relative movement of the vehicle 100, for example the window frame, relative to the horizon. The use of the trajectory planning signal 135 is advantageous compared to sensors, for example in a smartphone, because all relevant information is known in the preparation phase. As a result, time delays can be avoided, which is advantageous in terms of the anti-motion sickness effect of the solution presented here.

[0033] According to an embodiment, the display signal 140 read by means of the reading device 125 comprises a plane parameter. The plane parameter represents the number of movable display planes of at least one application displayed on the screen 110. A display plane is, for example, the intermediate plane between the displayed image content 115 in the foreground and the background image content 150 displayed as background. The determining device 130 is configured in this case to determine the image motion signal 145 using the plane parameter in order to move at least one display plane of at least one application displayed on the screen between the background image content 150 and the image content 115 relative to the displayed image content 115. If at least one application displayed on the screen 110 is able to move on several planes, for example on the foreground, the intermediate plane and the background, the movement for the other planes is also determined when determining the image motion signal 145.

[0034] According to the embodiment shown here, the determining device 130 is furthermore configured to provide the image motion signal 145 to the interface 155 to the screen 110 in order to manipulate the movement of the background image content 150 presented as a background for the displayed image content 115 of at least one application displayed on the screen 110 relative to the displayed image content 115.

[0035] Figure 2 A schematic view of a vehicle 100 with a device 105 according to an embodiment for preventing motion sickness when viewing image content 115 displayed on a screen 110 in a moving vehicle 100, in particular a highly automated moving vehicle 100, is shown. The vehicle 100 shown here and the device 105 shown here are similar or correspond to the vehicle 100 shown previously in accordance with the content of Figure 1

[0036] According to the embodiment shown here, the reading device 125 is additionally configured to read a user signal 205. The user signal is provided to the reading device 125, for example via a user interface 210. The user interface can be part of a device installed in the vehicle 100 or part of a mobile device, for example a smartphone, which is connectable or connected to the device 105 and additionally or alternatively to the vehicle 100 in such a way that signals can be transmitted. The user signal 205 represents a user-specific movement intensity, for example a user-specific movement frequency. The determining device 130 is in this case configured to determine the image motion signal 145 using the user signal 205. It is thereby advantageously possible to adapt the measures presented here for avoiding motion sickness to the individual needs of the user, for example by adapting the intensity or frequency of the movement of the background image content 150 presented as a background for the displayed image content 115 of at least one application displayed on the screen 110 relative to the displayed image content 115.

[0037] ​Furthermore, the determining device 125 is configured according to the embodiment shown here to additionally read a seat position signal 215. The seat position signal 215 represents an orientation of a seat position of a viewer of the screen 110 with respect to a driving direction of the vehicle 100. The determining device 130 is then configured to determine the image motion signal 145 using the seat position signal 215. Here, the seat position signal 215 is exemplarily provided by a mobile device 220. The mobile device 220 is for example a smartphone having sensor devices for determining an orientation of a user of the smartphone, for example a gyro sensor device. Advantageously, it is thus possible to adapt the following movement: the movement of the background image content 150 presented as a background to the displayed image content 115 with respect to the displayed image content 115, if there is an increased susceptibility to motion sickness at the user, for example in the case of a seat position against the driving direction. It is possible to determine the image motion signal 145 using the user signal 205 and the seat position signal 215 additionally in order to set the movement of the background image content 150 correspondingly.

[0038] The reading device 125 is also configured according to the embodiment shown here to read an orientation signal 225. The orientation signal 225 represents an orientation of an image format of the image content 115 displayed on the screen 110 as a narrow format or a landscape format. In this case, the determining device 130 is configured to determine the image motion signal 145 using the orientation signal 225 additionally. Optionally, the orientation signal 225 additionally comprises information about an orientation of the screen 110, for example if the screen 110 is part of the mobile device 220. The orientation signal 225 for example comprises: whether the screen 110 is oriented in a horizontal orientation or in a vertical orientation. The orientation signal 225 is exemplarily provided to the device 105 here via the interface 155 of the screen 110. Alternatively, the orientation signal 225 can also be provided for example by the mobile device 220, in particular using sensor devices having an orientation sensor, for example a gyro sensor device.

[0039] Figure 3 A schematic diagram of a vehicle 100 having a device 105 according to an embodiment for preventing motion sickness when viewing image content 115 displayed on a screen 110 in a vehicle 100 driving, in particular a highly automated vehicle 100 driving, is shown. The vehicle 100 shown here and the device 105 shown here are similar to or correspond to the embodiments described previously in accordance with Figure 1 or Figure 2 .

[0040] The device 105 is part of a mobile device 220 according to the embodiments shown here, for example part of a smartphone or a laptop. The screen 110 is implemented here as a display of the mobile device 220, alternatively the screen 110 can also be implemented as a stationary display which is fixedly installed in the vehicle 110. Furthermore, the screen 110 can also be implemented as a display element of a display device for augmented reality (AR) or virtual reality (VR), for example as a microdisplay of VR glasses. The screen 110 is configured to display the image content 115 using the image motion signal 145 and to display or realize a movement which is a movement of at least one background image content 150 which is presented as a background for the displayed image content 115 of an application displayed on the screen 110 relative to the displayed image content 115.

[0041] Here, in addition to the mobile device 220 with the device 105, the vehicle 100 exemplarily comprises a trajectory planning control unit 120 which provides the device 105 with a trajectory planning signal 135. The trajectory planning control unit 120 of the vehicle 100 for a highly automated driving vehicle 100 is configured to calculate a favorable route progression on the basis of vehicle sensor information and available map data. This also includes acceleration maneuvers, braking maneuvers and cornering maneuvers. Using the trajectory planning signal 135, in order to determine the image motion signal 145, parameters relevant to motion sickness are calculated, in particular the lateral and longitudinal accelerations to be expected during the time are calculated.

[0042] The vehicle 100 optionally comprises a communication module which is connected or connectable in a signal-transmissible manner with the trajectory planning control unit 120 and the device 105. The communication module transmits all the information relating to motion sickness, for example the trajectory planning signal 135, to a terminal device connected with the vehicle 100, for example to the device 105 or to a screen, for example via a radio connection or via transmission by cable. Furthermore, the device 105 optionally comprises a receiving unit. The receiving unit is configured to maintain a connection with the vehicle 100 permanently and to receive information relating to motion sickness from the vehicle 100. In addition, the device 105 has a background motion effect control unit according to an embodiment. The determining means of the device 105 optionally comprise the background motion effect control unit. The background motion effect control unit is configured to calculate an optimum movement direction and movement strength between a background and a foreground for all currently displayed applications. The movement is calculated on the basis of the lateral and longitudinal accelerations to be expected, optionally taking into account other factors, for example taking into account user-specific requirements or the orientation of the screen. In addition to calculating the strength and direction of the background motion effect, that is to say the movement of at least one background image content 150 displayed on the screen 110 as a background presented for the displayed image content 115 relative to the displayed image content 115, here also the temporal synchronization of the information is ensured.

[0043] Figure 4 A flowchart of a method 400 for preventing motion sickness when viewing image content displayed on a screen in a vehicle driving, in particular a highly automated driving vehicle, is shown according to an embodiment. The method 400 comprises a reading step 405 and a determining step 410. In the reading step 405, a trajectory planning signal and a display signal are read. The trajectory planning signal represents a planned trajectory of the vehicle. The display signal represents at least one application displayed on a screen. In the determining step 410, using the trajectory planning signal and the display signal, an image motion signal is determined for moving a background image content of at least one application displayed on a screen as a background presented for the displayed image content relative to the displayed image content. Here, the movement of the presented background image content relative to the displayed image content is made in order to prevent motion sickness when viewing image content displayed on a screen in a vehicle driving.

[0044] According to an embodiment, the method 400 further comprises a providing step 415. In the providing step 415, the image motion signal is provided to an interface to a screen in order to manipulate the movement of the background image content of at least one application displayed on a screen as a background presented for the displayed image content relative to the displayed image content. The screen is here part of a vehicle or a portable device.

[0045] The method 400 is implementable in case of using embodiments of the apparatus described in the foregoing and additionally or alternatively is manipulable.

[0046] If embodiments comprise a "and / or" link between a first feature and a second feature, this is to be understood as meaning that the embodiment has according to one implementation form both the first feature and the second feature, while according to another implementation form either only the first feature or only the second feature.
