Dynamic AR cues

Abstract

The invention relates to a device for improving the visualization of a prompt in a motor vehicle and a corresponding system, method and computer program. The contact-analog head-up display places information in direct contact with the surrounding environment. In contrast to conventional head-up displays, these information appears as part of the surrounding environment. The object of the invention is the placement of an information container at a distance x in front of the vehicle, which becomes larger in dependence on the reduction of the distance x and is placed fixedly in relation to the surrounding environment in order to produce the effect of a container which is positioned in reality. Since the direct reality reference it is immediately apparent that the container disappears when it reaches its position in the surrounding environment, that is to say there is a clear communication of the information disappearance and when the information disappears. In contrast to this, the demand for interaction can be communicated by the stillness of the element. It is thus immediately apparent that an action is required in order to exit the pop-up window or to trigger an action thereby.

Description

Technical Field

[0001] The present invention relates to a device for improving the visualization of information in a motor vehicle, as well as a corresponding system, method, and computer program. Background Art

[0002] Information pop-ups are an integral component of modern interactive systems, such as PCs, smartphones, tablets, and even vehicles. Conventional implementations often utilize timeouts to limit the display time of information that is generally only temporarily relevant, such as incoming messages or, in the context of a vehicle, information about the vehicle's status (e.g., "Refill wiper fluid"). However, with these implementations, it's impossible for the user to predict how long the pop-up will remain visible. Furthermore, its essentially temporary nature isn't immediately apparent, making it unclear to the user whether an action is necessary or not. Furthermore, due to the restricted field of view in a head-up display, it's often technically impossible to directly mark objects in the surroundings. Even with the maximum field of view (i.e., 100% windshield coverage), the relevant objects become visible only very late or, especially at higher speeds, only briefly.

[0003] Publication US 2019 / 0204104 A1 discloses a "vehicle interior system" that displays a symbol showing a device. A head-up display is used to improve the visibility of the device. The device graphic (Einrichtungsfigur) showing the device is positioned so that it overlaps with a virtual line parallel to the lane from the driver's perspective. The position above and below the display position overlaps with the road surface in front. A disadvantage of this is that the disclosed teachings involve improving the visibility of the device. Driving assistance information and / or other relevant information are not conveyed to the driver.

[0004] US Patent Publication No. 10,332,292 B1 discloses an augmentation system that supplements a person's field of view of at least one real vehicle or a virtual vehicle of the surroundings through which the vehicle is traveling. The system may include a receiver configured to receive data signals representative of the vehicle's operation and objects in the surroundings through which the vehicle is traveling. The system may also include a converter connected to the receiver. The converter may be configured to convert the data signals into display data representative of the vehicle's operation and objects in the surroundings through which the vehicle is traveling. The converter may also be configured to transmit the display data to a display connected to the converter and to display an image representative of the display data from the vehicle in the person's field of view to supplement the person's view. This augments the driver's perception. However, a disadvantage is that the display can easily become confusing and overloaded. The disclosed teachings do not provide any information on how to mitigate data overload and stimulus overload for the driver. The disclosed teachings only indicate how existing objects can be highlighted through augmented reality.

[0005] An augmented reality (AR) method and a device for driving assistance are known from the publication US 2020 / 0324787 A1, and the method and device are applied in the technical field of AR. The method comprises the following steps: determining driving assistance information based on information detected during the driving process and displaying virtual three-dimensional display information corresponding to the driving assistance information. In the present invention, AR technology can be applied during vehicle driving so as to support the driver in better detecting driving information during vehicle driving and the user experience can be improved. The disadvantage here is that the disclosed teaching includes the display (Darstellung) of driving assistance information. The effective range and especially the display duration of the driving assistance information are not conveyed to the driver. As a result, the driver may become nervous and have to focus on the faded-in driving assistance information in order to detect this information before it is no longer faded in. This leads to a high degree of distraction for the driver. Summary of the Invention

[0006] The present invention is aimed at providing an improved feasibility of conveying information to the driver in an easily understandable and easily detectable manner. Preferably, the driver should direct his or her sight toward the road direction.

[0007] This object is achieved by a device for improving the visualization of information in a motor vehicle, comprising:

[0008] an input interface for receiving reminder data containing information about the reminder and vehicle data containing information about the vehicle status;

[0009] an analysis unit for determining a display for a prompt based on the prompt data and the vehicle data and for generating a control command for controlling the AR display device based on the display for the prompt;

[0010] An output interface for transmitting control commands to an AR display device, wherein the control commands result in a dynamic display of the prompt, wherein a valid range for the prompt can be communicated based on the dynamics of the prompt display.

[0011] Furthermore, the above-mentioned object is achieved by a system for improving the visualization of information in a motor vehicle, the system comprising:

[0012] a device as previously defined; and

[0013] AR display devices, in particular heads-up displays in motor vehicles, are used to output dynamic representations of prompts in response to control commands of the device.

[0014] Furthermore, the above-mentioned object is achieved by a method for providing an improved visualization in a motor vehicle, comprising:

[0015] - receiving reminder data with information about the reminder and vehicle data with information about the vehicle status;

[0016] - determining a presentation for a prompt based on the prompt data and the vehicle data;

[0017] - generating a control instruction based on the display of the prompt to control the AR display device;

[0018] The control command is transmitted to the AR display device, wherein the control command causes a dynamic display of the prompt, wherein the dynamics of the prompt display can be used to convey the validity range for the prompt.

[0019] The input interface provides a cost-effective device that can preferably be used with existing systems, modules, and units installed in a motor vehicle. The input interface can be designed to be wired and / or wireless and preferably supports one or more communication protocols. An analysis unit can determine a favorable display for the prompt, wherein the visibility of the prompt symbol for the driver is improved and the driver can intuitively and easily detect the effective range of the prompt. Since a favorable display can be determined based on prompt data and vehicle data, the prompt symbol to be displayed can be dynamically and context-dependently depicted. This improves road traffic safety. The output interface provides a cost-effective device that can preferably be used with existing output devices. Using an input interface for receiving data containing information about prompts for the driver provides a technically simple and low-cost device that, in particular, does not require its own design for detecting information. Therefore, the device can be integrated into existing navigation or infotainment systems. Components already installed in the motor vehicle can be used for display using the output interface. Furthermore, it is conceivable to retrofit an AR display device and / or use multiple AR display devices in combination. Preferably, the favorable display includes a container positioned in the area in front of the motor vehicle.

[0020] In a preferred design of the present invention, it is provided that the output interface is configured to transmit control instructions to an AR display device in the form of an ARHUD and is preferably configured to be installed in a motor vehicle and is particularly preferably part of an onboard computer, infotainment and / or navigation system. As a result, the driver can select a configuration that is easy for him to understand. The acceptance, comfort and comprehensibility of the system can be improved and enhanced. The control instructions for the AR HUD enable improved visualization of information for the driver. In particular, the driver can direct his gaze to the lane without having to look at an additional display in the motor vehicle. Safety in road traffic is improved.

[0021] In another preferred embodiment of the present invention, the analysis unit determines a control command that causes a dynamic display of a warning, wherein the dynamic display includes the display of a countdown, wherein the countdown can preferably be displayed graphically as a bar and / or numerically as a percentage. This allows the driver to be informed of the validity range, in particular the validity duration, of the warning in a directly understandable manner.

[0022] In another preferred embodiment of the present invention, the validity range of the prompt includes location, time, and / or vehicle status-dependent validity. This allows prompts to be output only when information is to be transmitted to the driver or an operation is to be performed by the driver. This improves and enhances system acceptance, comfort, and comprehension. In particular, it prevents overloading the field of view with unnecessary prompts. For example, the maximum permitted speed may be displayed only when the driver exceeds the maximum permitted speed or a predefined threshold.

[0023] In another preferred embodiment of the application it is provided that the input interface is configured to receive vehicle data with information about a vehicle state, wherein the vehicle state comprises a speed, a direction and / or a position of the motor vehicle. Thereby, the effective range of the prompt can be determined improved. In particular, the effective range can be determined dynamically for the respective driving situation. The comfort is increased.

[0024] In another preferred embodiment of the application it is provided that the analysis unit determines a control instruction which causes a dynamic showing of the prompt in the form of an information container, wherein the information container is fixedly positioned in front of the motor vehicle at a predefined distance via augmented reality with respect to the surrounding environment. Here, the information container can be enlarged with decreasing distance in order to create the effect of a container positioned in reality. Thereby, the driver intuitively recognizes the effective range of the prompt. The driver can concentrate on driving, since he detects the prompt comprising the effective range, e.g. a traffic sign. The driver's memorization is not necessary. The device can communicate information most intuitively.

[0025] In another preferred embodiment of the application it is provided that the analysis unit determines a control instruction which causes a disappearance of the information container upon reaching its position in the surrounding environment, preferably based on whether the information container comprises temporarily relevant information, or causes a disappearance of the information container in front of the motor vehicle upon and after reaching its position in the surrounding environment, preferably based on whether an operation of the driver is necessary. Thereby, the driver can be acutely and directly intelligibly prompted for the need of an operation when necessary.

[0026] Further preferred embodiments of the application result from the remaining features according to the application. In particular, it can be provided that the contact-analog head-up display places the information in direct contact with the surrounding environment. In contrast to conventional head-up displays, the information appears as part of the surrounding environment. The object of the application is the placement of the information container at a distance x in front of the vehicle, which is placed fixedly with respect to the surrounding environment according to an enlargement with decreasing distance x in order to create the effect of a container positioned in reality. Since the direct reality reference is apparent, the container disappears upon reaching its position in the surrounding environment, which is to say there is a clear communication of the information disappearance and when it disappears. In contrast thereto, the need for interaction can be communicated by the element's stillness. That is to say, shortly before reaching the position of the information container, the information container remains fixedly in the field of vision and is "pushed" in front of the own vehicle. Thereby, it is directly apparent that an operation is necessary in order to exit the pop-up window or to thereby trigger an action, e.g. a route guidance. It is apparent that this type of 3D pop-up window can be used for a large number of information, e.g. for the communication of the remaining distance with respect to a navigation destination, for the communication of nearby charging stations and other points of interest, e.g. sightseeing objects.

[0027] The various embodiments of the invention mentioned in this application can be advantageously combined with one another, unless they are implemented otherwise in the individual cases.

[0028] A heads-up display (HUD; literally "heads-up display") is a display system in which the user maintains their gaze direction and, therefore, their head position, as information is projected into their field of view. In addition to pilots, these users also include vehicle drivers. In particular, augmented reality (AR) can be combined with HUDs. AR here means computer-assisted enhancement of reality perception. This information can respond to all human sensory modalities. However, augmented reality is often understood solely as a visual display of information, i.e., the supplementation of images or videos with additional computer-generated information or virtual objects by means of fading in / overlaying.

[0029] The information container can in particular include a frame around the indication in order to achieve improved positioning and increased recognition, as well as easier detection of the indication by the driver. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 6 A schematic representation of the steps of the method according to the invention is shown. DETAILED DESCRIPTION

[0037] Figure 1 A schematic illustration of a device 10 for improving the visualization of information in a motor vehicle is shown. The device 10 comprises an input interface 12 , an evaluation unit 14 , and an output interface 16 .

[0038] Input interface 12 is configured to receive data, including prompt data containing information about prompts and vehicle data containing information about the vehicle's status. This data may, for example, include speed or navigation instructions and may originate from a speedometer, a GPS receiver, and / or a navigation system. Furthermore, this data may include sensor data from driver assistance systems, such as detected vehicles ahead, sign recognition, and the like. For this purpose, input interface 12 is preferably connected to a vehicle-internal transmission network. Furthermore, input interface 12 may also be configured for wireless communication or for connection to a dedicated (e.g., wired) transmission network.

[0039] The analysis unit 14 is configured to receive data and generate control commands, wherein the control commands cause a dynamic display of prompts. The dynamic nature of the prompt display can be used to indicate a validity range for the prompt. This validity range can include, among other things, temporal, locational, and / or vehicle state-dependent validity. The analysis unit 14 determines the display of the prompt based on the prompt data and the vehicle data. The display can, for example, include a change in size, color, color saturation, or transparency, a simplification of prompt symbols, and / or the duration of display of one or more prompt symbols.

[0040] The output interface 16 is configured to transmit control instructions to the AR display device. The output interface 16 can be configured for communication similarly to the input interface 12. Obviously, the input interface 12 and the output interface 16 can also be combined to form a communication interface for sending and receiving.

[0041] Figure 2 A schematic illustration of a system 18 according to the invention is shown with an apparatus 10 and an AR display device 20 with a projection unit 22 .

[0042] Device 10 receives data including alert data and / or vehicle data, such as the speed of the vehicle, data from an eye-tracking sensor, data regarding relative traffic conditions, location data of the vehicle, data regarding the location of a hazard, navigation data, and the direction of the vehicle.

[0043] Based on this data, the device 10 generates control commands for the AR display device 20 and thus causes a dynamically modified display of, in particular, a notification 24 on the windshield 26 of the motor vehicle. In the example shown, the AR display device 20 comprises a heads-up display, wherein the projection unit 22 is movably designed and can be moved, for example, by means of an actuator, so that the notification 24 can be projected onto the windshield 26 at a certain position in the driver's field of view. In particular, the size of the notification 24 can be changed. Thus, the notification 24 can be displayed directly on the windshield 26 of the motor vehicle.

[0044] Figure 3A schematic illustration of a variant of the system 18 according to the invention is shown in a motor vehicle 28. The system 18 according to the invention comprises an apparatus 10 and an AR display device 20. In the example shown, the AR display device 20 comprises a projection unit 22 which can project onto a windshield 26 of the motor vehicle 28 (not shown in further detail).

[0045] As described above, the device 10 receives data including prompt data and / or vehicle data. In the example shown, the system 18 is connected to a vehicle module 30, such as a navigation system, and receives navigation data. Obviously, the system 18 can also be configured as a separate unit together with the navigation system. In the example shown, the navigation system can form a unit that determines the information to be transmitted to the driver (such as a navigation request). Additional data can come from a front camera 32, for example, to determine the situation in front of the motor vehicle 28. Obviously, other sensors known in principle in the prior art can also be used. In particular, sensor data fusion of data from multiple sensors can be achieved in order to achieve higher data quality. In addition, the vehicle module 30 can also include a control device for the motor vehicle 28, wherein necessary operations can be conveyed to the driver by means of prompts 24, such as filling up the wiper fluid, changing a fault light, or the like.

[0046] Device 10 analyzes the received data and determines a control command that causes a dynamic display of prompt 24, wherein the dynamics of the display of prompt 24 can be used to convey the validity range for prompt 24. As described above, prompt 24 can be output based on the display and can be recognized by the driver.

[0047] exist Figure 4 The schematic diagram shows a situation in road traffic in which a motor vehicle 28 receives a navigation instruction to turn left into a junction in the direction of travel. This instruction 24 is positioned at the level of the junction in the direction of travel. Furthermore, a sensor (not shown) of motor vehicle 28 detects that refueling of motor vehicle 28 is necessary. Therefore, instruction 24, which requests the driver to refuel, is positioned in front of motor vehicle 28 and is shown in this example as being pushed in front of motor vehicle 28.

[0048] Obviously, the illustration of prompt 24 on the lane is only schematic and greatly simplified.In addition, obviously, the form of prompt 24 and the information connected therewith and / or the request to the driver are only selected by way of example.

[0049] exist Figures 5a to 5c In FIG, the output of the system 18 in the form of a prompt 24 is schematically displayed on the AR display device 20, which is contained in the information container 34. Figures 5a to 5cSchematically illustrates the temporal sequence of the travel of motor vehicle 28 from the driver's perspective.

[0050] exist Figure 5a In the situation shown in FIG, navigation instructions 24 are positioned farther in front of vehicle 28. Navigation instructions 24 include a left-pointing steering arrow. Another instruction 24 includes information that a restriction no longer applies on the road section and is indicated by a traffic sign. This instruction 24 is positioned closer to vehicle 28 than the steering arrow.

[0051] exist Figure 5b In the situation shown in , navigation prompt 24 is positioned closer to motor vehicle 28. This impression is achieved by showing that navigation prompt 24 is larger. In particular, the size of navigation prompt 24 can change with the speed of motor vehicle 28 and / or the distance traveled, thereby creating the impression that navigation prompt 24 is fixedly positioned in front of motor vehicle 28 and that motor vehicle 28 is traveling towards navigation prompt 24. Prompt 24 with the information that the restriction no longer applies on the road section is positioned directly in front of motor vehicle 28 and therefore remains continuously displayed in front of motor vehicle 28, as if motor vehicle 28 has pushed prompt 24 in front of it. Obviously, it can also be provided that prompt 24 fades out after a predefined and particularly configurable time interval. In particular, prompt 24 with the information that the restriction no longer applies on the road section is positioned at a position where the restriction no longer applies on the road section.

[0052] exist Figure 5c In the situation shown in , the navigation prompt 24 is positioned directly in front of the motor vehicle 28. Therefore, it should be conveyed that a lane change or a steering operation should be performed. The navigation prompt 24 is preferably no longer displayed after passing because the turn or lane change has been performed. Even when no action is taken, the navigation prompt 24 is no longer displayed because it is no longer applicable. The validity of the navigation prompt 24 is conveyed by positioning and gradually increasing the size of the display. The prompt 24 with information that the restriction on the road section is no longer applicable continues to be applicable and can therefore be continued to be displayed. Obviously, the driver can reply as follows through an operating input, that is, he has noticed the prompt 24 and that the prompt should no longer be displayed. In addition, it can be arranged that the prompt 24 fades out after a predefined time interval.

[0053] Alternatively, the following process for displaying hint 24 can also be performed. Hint 24 is positioned vertically, similar to a road sign containing hint 24 and positioned, for example, one meter above the road surface via AR. Hint 24 is modified via AR as long as it is within the occupant / driver's field of view. If hint 24 leaves the field of view due to AR modification, it is moved to the nearest edge of the field of view. AR modification includes, in particular, changing the size of hint 24 as a function of distance traveled or speed of travel, thereby creating the impression of driving towards hint 24.

[0054] The prompt 24 is located at a certain distance in front of the position of the motor vehicle 28. This results in a symbol size of at least 60 pixels, for example. This size is configurable. The character height of the prompt 24 can be scaled accordingly.

[0055] The time interval for fading in may be, for example, 266 ms. The prompt 24 is preferably enlarged until the maximum font size is reached. Here, the prompt 24 may maintain its maximum size for, for example, 1000 ms before being faded out to transparency within 266 ms.

[0056] If the vehicle reaches 280 km / h, a timer can be started, wherein after a time interval of, for example, 1000 ms at V = 0 km / h, the prompt 24 (as described above) is faded out until it is completely transparent. If the vehicle 28 is put into motion again within a shorter time, the prompt 24 continues to be displayed and the method is continued.

[0057] The starting size of the prompt 24 can be determined, for example, based on the vehicle's speed. For example, at very low speeds, such as in a traffic jam, the size may increase from the minimum value to the maximum value over a period of, for example, 60 seconds. To prevent this, the starting size should be based on the vehicle's speed.

[0058] If the vehicle 28 is operating without active route guidance, the path that the vehicle 28 will take is unknown to the system 18. Therefore, a fixed position of the prompt 24 can only be implemented with difficulty. Preferably, an implementation scheme similar to a spear (Lanzenanalogie) can be used. Here, the prompt 24 is shown in front of the vehicle 28, as if the prompt 24 were installed at the tip of a spear in the direction of travel from the perspective of the vehicle 28. The length of the spear (not shown) can be used to produce an AR effect. Here, the length of the spear can decrease as the distance traveled is reduced, so that the prompt 24 is closer to the vehicle 28, that is, it is shown larger. For example, the integral of the speed can be used as a quantity for the distance traveled.

[0059] The perceptible size change of indicator 24 should reflect the speed, and the longitudinal position of indicator 24 should directly and dynamically reflect the speed of vehicle 28. This means that indicator 24 should become larger at high speeds. The curve should therefore preferably have no influence on the display of indicator 24, with only the distance covered and the speed being influential.

[0060] It is obvious that the above-mentioned sizes and time intervals are selected only as examples and are in particular configurable.

[0061] exist Figure 6Schematically, the steps of the method according to the present invention for improving the visualization of a message 24 in a motor vehicle 28 are shown. The method can preferably be carried out using the system 18 and / or the device 10 (as described above).

[0062] In a first step S1 , information data with information about the notification 24 and vehicle data with information about the vehicle state are received.

[0063] In a second step S2 , a display for the prompt 24 is determined based on the prompt data and the vehicle data.

[0064] In a third step S3 , the control instructions generated are configured based on the output so as to control the AR display device 20 .

[0065] Finally, in a fourth step S4 , the control command is transmitted to the AR display device 20 .

[0066] In this case, the control command causes a dynamic display of the prompt 24 , wherein the validity range for the prompt 24 can be conveyed depending on the dynamics of the display of the prompt 24 .

[0067] The present invention has been described in detail. Obviously, the embodiments selected are merely exemplary and are intended to facilitate a better understanding of the present invention. A skilled person will recognize that the present invention can be applied to a wide variety of prompts for information and requests to be conveyed to the driver. Furthermore, a skilled person will recognize that the present invention can also be applied to multiple prompts.
