Description

The invention relates to a method, a device and a corresponding computer program which are designed to support the occupant of a vehicle in operating (e.g. using) a display operating system, in particular a touch-sensitive screen or a touch-sensitive projection.

A vehicle may include a user interface with a display operating system, the display operating system having, for example, a touch-sensitive screen and/or a touch-sensitive projection.

This document deals with the technical task of increasing the comfort, effectiveness and/or reliability of the operation of a display and operating system of a vehicle. In particular, the technical task includes providing improved performance, reliability and/or an improved experience for the user (e.g. driver or passenger) of the vehicle when using the display operating system.

The task is solved by each of the independent claims. Advantageous embodiments are described, among other things, in the dependent claims. It should be noted that additional features of a patent claim dependent on an independent patent claim can form a separate invention independent of the combination of all the features of the independent patent claim, without the features of the independent patent claim or only in combination with a subset of the features of the independent patent claim can be made the subject of an independent claim, a division application or a subsequent application. This applies equally to technical teachings described in the description, which may constitute an invention independent of the features of the independent patent claims.

According to one aspect, a device for operating a display operating system of a (motor) vehicle is described. The display operating system may include a proximity-sensitive and/or touch-sensitive screen. Alternatively or additionally, the display operating system can include a projection or a three-dimensional representation (possibly also projection). One or more virtual control elements can be provided via the display operating system with which a user of the vehicle can interact (e.g. to effect user input).

The device is set up to determine vehicle data in relation to at least one operating parameter and/or in relation to a driving context and/or in relation to a driving situation of the vehicle. The vehicle data can be determined based on the sensor data from one or more vehicle sensors (e.g. an acceleration sensor) and/or from one or more environmental sensors (e.g. a camera, a lidar sensor, a radar sensor and/or an ultrasonic sensor) of the vehicle.

The device is further set up to vary the display area of a virtual control element of the display control system and/or the corresponding control area of the virtual control element and/or the feedback area of the virtual control element depending on the vehicle data.

The display area can be a spatial subarea of the display operating system in which a symbol for the virtual control element is displayed. Furthermore, the operating area can be a spatial subarea of the display operating system in which a user can actuate the virtual operating element. The feedback area of the virtual control element can be a spatial subarea of the display control system in which acoustic and/or haptic feedback regarding the virtual control element takes place (also to be understood as being triggered and/or transmitted to the user).

It should be noted that the control element and/or the display operating system does not necessarily have to have all three of the areas. In particular, only two of the three areas described in this document can be varied or provided in the display operating system.

The display-operating system can be part of the on-board computer or the display-operating interface of the vehicle's on-board computer. The device can comprise or be part of the display operating system.

The term “operation”, “operating process” or use of the display operating system refers in particular to an operation of the vehicle, in particular a vehicle system (e.g. an on-board computer, information system, etc.), which is superimposed on the driving activity or is carried out at least partially simultaneously with the driving activity /or communication system of the vehicle).

In the context of this document, the term “operation” can be interpreted in particular as controlling, changing an operating mode, and/or varying one or more operating parameters.

Varying can also be understood as (e.g. dynamic) adapting. Alternatively or additionally, varying can also include or be an adjustment (e.g. valid until a change or until further adjustment).

For example, varying, in particular adapting, can apply case-specifically or for a specific operating process. This can involve a short-term variation (in terms of effect) for a duration of 0.1; 0.2, 0.5; Act 1, 2, 5 seconds. The setting can go beyond one operation or also affect one or more further (later) operations. For example, a setting can (also) affect one or more subsequent operations and/or similar operations (e.g. operations with similar parameters or parameter patterns).

In particular, the display area of a virtual operating element of the display operating system and/or the corresponding operating area of the virtual operating element and/or the corresponding feedback area of the virtual operating element are adapted to one another in an appropriate manner. The variation can relate to a relationship (in particular to be understood as a one-sided or reciprocal relationship) of the respective parameters to one another, e.g. a mathematical relationship between the parameters, in particular a proportion, mathematical formula, etc.

• • erstes Verhältnis eines Parameters des Anzeige-Bereichs zu einem Parameter des Bedien-Bereichs und/oder einem Parameter des Feedback-Bereichs; und/oder
• • ein zweites Verhältnis eines Parameters des Bedien-Bereichs zu einem Parameter des Anzeige-Bereichs und/oder einem Parameter des Feedback-Bereichs; und/oder
• • ein drittes Verhältnis eines Parameters des Feedback-Bereichs zu einem Parameter des Bedien-Bereichs und/oder einem Parameter des Anzeige-Bereichs;

variiert, insbesondere angepasst, werden.For example, (alternatively or additionally with scaling and/or moving the control element as a whole):

• • first relationship of a parameter of the display area to a parameter of the operating area and/or a parameter of the feedback area; and or
• • a second ratio of a parameter of the operating area to a parameter of the display area and/or a parameter of the feedback area; and or
• • a third ratio of a parameter of the feedback area to a parameter of the operating area and/or a parameter of the display area;

varied, especially adapted.

The device can preferably be designed to carry out vehicle-specific, case-specific, driving situation-specific and/or user-specific variation (e.g. more or less permanent adjustment and/or dynamic adjustment) during operation.

The display area (or a parameter of the display area) of a virtual control element can be varied in relation to the corresponding control area (or a parameter of the control area) of the virtual control element and / or to the corresponding feedback be executable in the area.

The device can increase an anticipatory effect and/or success when using the display operating system (and thus the vehicle as an overall product).

The vehicle data can, for example, be characteristic of one or more current and/or predicted odometric variables for a future point in time, in particular: a longitudinal and/or lateral acceleration and/or a vertical dynamic acceleration of the vehicle; and/or a current and/or a vehicle speed and/or vehicle acceleration predicted for a future point in time; and/or one or more parameters of the drive system and/or braking system of the vehicle; and/or a current and/or a predicted future point in time yaw and/or pitch of the vehicle.

In particular, the vehicle data (vehicle parameters) can identify a control signal that has been initiated (e.g. not yet or not fully implemented) and/or is being implemented. For example, vehicle data can be indicative of a control signal that has not yet been (fully) implemented to a drive system and/or braking system and/or steering system and/or vertical dynamics system and/or actuator of the vehicle. Anticipatory variation can be achieved.

In particular, the vehicle data can identify information from a navigation system of the vehicle and/or information from a section of a digital map (relevant to the current position, route or journey of the vehicle).

For example, vehicle data can include a road course (e.g. curves, inclines, slopes, road inclinations, etc.) and/or road arrangements (e.g. intersections, roundabouts, entrances and exits) and/or road roughness (e.g. ruts, potholes, etc.) and/or Mark traffic signs, traffic lights and/or traffic light phases.

In particular, vehicle data can characterize an operating parameter of a driver assistance system or a functionality for at least partially automated driving and/or parking. For example, regarding the current and/or expected level of automation of the journey or a parking or parking process in the near future.

The term “mark” can in particular be understood as representing and/or characterizing (directly or indirectly, e.g. according to a stored formula).

In particular, vehicle data can characterize a current vibration and/or acceleration of the passenger cell of the vehicle that is predicted for the near future.

For example, vehicle data characterizing the direction and/or the amplitude and/or the acceleration and/or the frequency of vibration (current and/or expected at the time of operation of the virtual control element) can be determined and taken into account in the method. In particular, vehicle data may include or take into account data from an acceleration sensor and/or vibration sensor of the vehicle (concerning the passenger compartment of the vehicle).

A corresponding prediction can be made, for example, from the data of the course of a road section ahead (e.g. curves ahead), the condition of the road section (e.g. slope, inclination, unevenness of the road surface, roughness, potholes), and / or one (e.g. from a driver assistance system and /or driver of the vehicle) planned maneuvers. When we talk about prediction for the near future in the context of this document, this means in particular the prediction in relation to the time interval of the (predicted, already recognized or in progress) operation of the virtual control element.

For example, an operation of the virtual control element (e.g. by the approach of the user's hand) can be recognized or predicted. Vehicle data (e.g. regarding the time interval for operating the virtual control element) can then be determined and/or taken into account.

Alternatively or additionally, the vehicle data can display the type of driving situation currently or predicted for a future point in time (e.g. from a list of predefined types or patterns).

In the context of this document, the term “driving situation” can be understood, for example, as a specific situation characterized by an arrangement, action or interaction of road users or by certain driving parameters of road users.

In particular, the meaning of the term “situation” or “driving situation” differs from the meaning of the term “traffic situation” that is often used colloquially, which rather summarizes general categories such as “free traffic”, “dense traffic”, “slow-moving traffic”, “ Traffic jam”, “end of traffic jam” etc. corresponds. In particular, a driving situation is (rather) characterized by influences that are caused by specific road users or their movement (not just their statistical quantity).

In particular, a driving situation is (rather) characterized by a specific pattern (also to be understood as a data pattern), e.g. a pattern characterizing an arrangement and/or speed of the objects and/or a pattern of the parameters of the driving situation. The driving situation can also be characterized by a spatial pattern of so-called open spaces in the area surrounding the vehicle. For example, a trigger condition can relate to such features or corresponding parameters of the driving situation.

• • eine (bestimmte) räumliche Verteilung der Verkehrsteilnehmer und/oder der Bewegungsparameter der Verkehrsteilnehmer, insbesondere ein Anordnungsmuster der Verkehrsteilnehmer in der Umgebung des (realen) Fahrzeugs,
• • eine (bestimmte) räumliche Verteilung unbeweglicher Objekte in der Umgebung des Fahrzeugs,
• • eine relative Position und/oder ein Bewegungsparameter zu bestimmten Arten von Spurmarkierungen, Verkehrszeichen, Ampeln (nicht notwendigerweise zu bestimmten Ampeln, etc.),
• • eine Information über die Vorfahrt des Fahrzeugs, insbesondere gegenüber bestimmten Verkehrsteilnehmern und/oder Verkehrsteilnehmern, die tatsächlich oder zumindest potentiell aus bestimmten Richtungen, z.B. einer querenden Straße von rechts oder von links kommen oder kommen können,
• • eine Information zu einer, z.B. einen Grenzwert überschreitenden, Handlung eines Verkehrsteilnehmers in der Umgebung des Fahrzeugs, wie z.B. ein Hupen, Lichthupen, Drängeln, Überholen des Fahrzeugs, ein Überholversuch und dergleichen.

The at least one driving situation can preferably be characterized by one or more of the features listed below:

• • a (certain) spatial distribution of the road users and/or the movement parameters of the road users, in particular an arrangement pattern of the road users in the area surrounding the (real) vehicle,
• • a (certain) spatial distribution of immovable objects in the area surrounding the vehicle,
• • a relative position and/or movement parameter to certain types of lane markings, traffic signs, traffic lights (not necessarily to specific traffic lights, etc.),
• • information about the right of way of the vehicle, in particular towards certain road users and/or road users who are actually or at least potentially coming from certain directions, e.g. a crossing street from the right or from the left,
• • Information about an action by a road user in the vicinity of the vehicle that exceeds a limit value, such as honking, flashing lights, jostling, speeding lent the vehicle, an attempt to overtake and the like.

Furthermore, the driving situation can be characterized by one or more parameters in connection with relevant traffic rules, traffic signs, right-of-way, traffic lights and/or traffic light phases.

The at least one driving situation can preferably be a driving situation that exceeds a certain limit value or a driving situation that is characterized by parameters that exceed certain limit values.

For example, the at least one driving situation can be a driving situation with an undesirable or dangerous approach to an object or a road user, with an acceleration value that exceeds a limit value, with an undesirable arrangement in relation to other road users, etc.

The driving situation can be a special situation (e.g. that occurs comparatively rarely) or a dangerous driving situation, e.g. a driving situation for which an increased risk is determined or assumed.

Alternatively or additionally, the vehicle data (part of the vehicle data) can be characteristic of a current and/or predicted trip context for the near future (e.g. of a few seconds), in particular highway driving, city driving, daytime driving, night driving, driving in the rain, in storms , in high or low lighting conditions, etc.

The driving context, in particular a driving context parameter, can be characteristic of lighting conditions, in particular a strength and/or direction of the lighting, a change in the lighting over the course of the journey (e.g. driving on avenues, bridges, winding roads, etc.) and/ or noise conditions, in particular noise from other vehicles, noise from one or more other occupants (e.g. certain voices), radio, etc.

For example, a current driving context and/or a driving context predicted for the near future (e.g. entering or exiting a tunnel, noise impact, e.g. due to the echo or other road users, etc.) can be taken into account.

As already stated, the display operating system can include a touch-sensitive screen. In this case, the display area, the operating area and/or the feedback area can each correspond at least partially to different sub-areas (or spatial sub-areas having or suggesting a third dimension) of the touch-sensitive screen. Alternatively or additionally, the display operating system can include a three-dimensional (e.g. generated by a 3D screen or stereoscopically) representation or a projection. In this case, the display area, the operating area and/or the feedback area can at least partially correspond to different three-dimensional subareas of the three-dimensional representation or projection.

The device can in particular be set up to determine a (mathematical) relationship (e.g. proportion, mathematical rule or function) between the display area and/or the corresponding operating area and/or the corresponding feedback area of the virtual operating element depending on the Vehicle data to vary.

The ratio can relate to: a dimension, in particular a spatial size, of the display area relative to the operating area and/or the feedback area; the shape of the display area relative to the control area and/or the feedback area; the location of the display area relative to the operating area and/or the feedback area; and/or the degree of overlap of the display area and the operating area and/or the feedback area.

By adapting the one or more (correspondingly defined) areas of a virtual control element depending on vehicle data, the comfort and reliability of the display control system of a vehicle can be increased in an efficient manner.

The device can be set up to have the display area and/or the operating area and/or the feedback area of a (further, optionally appearing, additional) adjacent virtual control element, which is adjacent to the virtual control element in the display operating system is arranged to vary depending on the display area and / or the operating area and / or the feedback area of the virtual control element and / or depending on the vehicle data.

For example, one or more of the three sub-areas of at least two adjacent (currently displayed adjacent) virtual control elements are varied in a manner coordinated between the two control elements. For example, the operating element is one of at least two operating elements, to which the user's operating action (e.g. the user's finger) is most likely directed. Another control shown nearby may be considered the adjacent control.

For example, when an approach to the control element and/or an operation of the virtual control element is detected, the control range and/or feedback range of one or more adjacent control elements can be varied (in some way). For example, the distance of the operating area and/or the feedback area of one or more adjacent operating elements (deviating from and/or disproportionate to the display area) can be increased. The display area and/or the operating area and/or the feedback area of the adjacent control element can be moved, reduced in size and/or changed in terms of their respective effect (in particular in at least one combination that is different, proportional or disproportionate to one another).

In this way, the comfort and reliability of the display operating system can be further increased.

The device can be set up to determine operating data relating to an operation of the one or more virtual control elements that has already been carried out and/or attempted by a user. The operating data can display the position (if necessary relative to the previous operating area) at which the attempted operation of the virtual control element took place. The operating area of the virtual operating element can then be set, in particular adapted, depending on the operating data. In this way, the comfort and reliability of the display operating system can be further increased.

The device can be set up to determine operating data relating to a plurality (e.g. hundreds, thousands, millions) of first operating processes. These can be determined using a backend server, stored and/or processed by it. The first operations can be carried out on one or more different (possibly identical) vehicles. On the basis of the operating data, frequency information can be determined or have been determined in relation to the frequency of different successful (e.g. flawless, borderline and/or unsuccessful) operating procedures in the plurality of first operating procedures. In particular, it can be determined or has already been determined how often the successful, unsuccessful or almost successful or almost unsuccessful operating process (e.g. information entry), in particular a certain unintentional operation or error of a certain type, occurs during the first operating processes.

Depending on the determined and/or aggregated (first) operating data, a parameter of the display area of the virtual control element and/or a parameter of the operating area and/or a parameter of the feedback area can then be varied in one or more (second) Operating processes of the display operating system can be effected.

For example, the device is set up to vary a parameter of the display area of the virtual control element and/or a parameter of the control area and/or a parameter of the feedback area, preferably for varying a ratio between at least two of the parameters mentioned, depending on the Frequency information.

For example, such a variation is effected when the frequency of unsuccessful (or just successful) operations is greater than a specific first frequency threshold and/or a variation is effected when the frequency of unsuccessful (or just successful) Operations are greater than a specific first frequency threshold.

The device can be set up to determine user data relating to the user of the display operating system. The user data can show, for example: an activity of the user; the user's viewing direction; and/or the user's attention in relation to the operation of the virtual control element. The display area and/or the corresponding operating area and/or the corresponding feedback area of the virtual control element can then be set, in particular adapted, depending on the user data. In this way, the comfort and reliability of the display operating system can be further increased.

According to a further aspect, a (road) motor vehicle (in particular a passenger car or a truck or a bus or a motorcycle) is described which includes the device described in this document.

According to a further aspect, a method for operating a display operating system of a (motor) vehicle is described. The method includes determining vehicle data in relation to an operating parameter and/or in relation to a driving context and/or in relation to a driving situation of the vehicle. The method further includes varying, in particular adapting, the Display area of a virtual control element of the display operating system and / or the corresponding operating area of the virtual control element and / or the corresponding feedback area of the virtual control element depending on the vehicle data.

According to a further aspect, a computer program, in particular a computer program product comprising a computer program, is described, wherein the computer program is designed to carry out at least one of the methods described in this document when it is executed on at least one computing unit. There can be several computer programs or a computer program product comprising several computer programs, which can be run, for example, on different computing units of the device or on several devices in order to carry out (if necessary together, in an information technology connection) at least one of the methods described in this document.

The computer program product can be designed as an update of a previous computer program, which includes the parts of the computer program or the corresponding program code, for example as part of a functional expansion, for example as part of a so-called “remote software update”. The computer program product includes in particular a medium readable by the data processing device, on which the program code is stored, or at least an encrypted file.

• 1 an exemplary vehicle with a display operating system;
• 2 an exemplary display operating system with a virtual operating element; and
• 3 a flowchart of an exemplary method for operating a display operating system of a motor vehicle.

As explained at the beginning, this document deals with increasing the comfort and reliability of operating a display operating system. In this context shows 1 an exemplary vehicle 100, which includes (eg in the interior of the vehicle 100) a display operating system 110. The display operating system 110 can, for example, have a touch-sensitive screen and/or a projector that is designed to produce a (two-dimensional or three-dimensional) representation or a display projection that a user can perceive (display area 201). can be operated, in particular operated, by the user (operating area 202), and/or with which a user of the vehicle 100 can trigger and/or receive feedback regarding an operation that has taken place and/or not taken place (feedback area 203). At least two of the three areas 201, 202, 203 of a control element 200 cannot or cannot always be congruent in the display control system 110. This allows the user to interact with the display operating system 110 much better.

A (control) device 101 of the vehicle 100, in particular of the display operating system 110, can be set up to control the display operating system 110 and/or to interpret a user input effected via the display operating system 110 in order to determine a function of the vehicle 100 to effect.

2 shows an exemplary display operating system 110 (eg in the form of a proximity-sensitive and/or touch-sensitive screen). The display operating system 110 may have a virtual operating element 200 with which the user of the vehicle 100 can interact. For example, the virtual control element 200 can be actuated by the user (eg pressed or selected with a finger) to effect user input.

The virtual control element 200 includes a spatial display area 201 in which a symbol for the virtual control element 200 is displayed. The display area 201 can, for example, correspond to a flat section of a touch-sensitive screen or a spatial sub-area of a (three-dimensional) representation or projection.

The virtual control element 200 further includes a spatial control area 202 that can be operated by the user of the vehicle 100 in order to operate the virtual control element 200. The operating area 202 can, for example, be a flat section of the touch-sensitive screen or a spatial sub-area correspond to the (three-dimensional) representation or projection.

Typically, the operating area 202 and the display area 201 and the feedback area 203 are essentially identical and/or congruent with one another. However, this can be disadvantageous in the dynamic operation of a vehicle 100 or in the operation of the vehicle 100 with many influences that the occupant's perception system experiences while driving. For example, dynamic operation of the vehicle 100 can lead to deviations between the user's visual behavior and the user's motor operating behavior.

This document therefore describes a display operating system 110 in which the operating area 202 and/or the display area 201 and/or the feedback area 203, in particular the relative relationship between the operating area 202 and the display Area 201 and / or the feedback area 203, a virtual control element 200 depending on vehicle data, e.g. at least one operating parameter of the vehicle 100, can be set and / or adjusted in order to increase the comfort and reliability of the display operating system 110.

This is to be understood in particular as meaning that one or more parameters of at least two of the three aforementioned (partial) areas 201, 202, 203 or a (mathematical) ratio of the parameters of at least two of the three aforementioned (a suggested or perceptible area and/or or a suggested or perceptible volume) areas 201, 202, 203 can be varied in different ways.

3 shows a flowchart of a (possibly computer-implemented) method 300 for operating a display operating system 110 of a vehicle 100. The method 300 includes determining 301 vehicle data in relation to an operating parameter and/or in relation to a traffic situation of the vehicle 100. Furthermore, the method 300 includes setting 302, in particular adapting, a display area 201 of a virtual control element 200 of the display control system (110) and/or a corresponding operating area 202 of the virtual control element 200 depending on the vehicle data.

The geometric area 201, which is used for displaying a virtual control element 200, and the corresponding sensitive (sensory) area 202 can therefore be designed variably. In particular, this can be done in such a way that these areas 201, 202 in the vehicle 100 are changed in relation to one another depending on one or more specific parameters or data. This can be carried out dynamically and/or depending on a vehicle-specific, context-specific, situation-specific and/or user-specific parameter.

A method 300 for operating a display operating system 110 of a vehicle 100 is thus described, in which a sensitive geometric (operating) area 202 belonging to a virtual operating element 200 is in relation to the geometric (display) area 201 in which the virtual control element 200 is displayed, and / or is varied in relation to the feedback area 203 in which feedback is triggered and / or transmitted.

In particular, the display operating system 110 of the vehicle 100 is or includes a touch screen and/or a gesture control (two-dimensional or three-dimensional).

The sensitive first geometric area belonging to the virtual control element 200 and which reacts to the operation by executing the operating action can be referred to as the operating area 202. The second geometric area in which the virtual control element 200 is displayed (for the user) can be referred to as the display area 201.

A (optionally provided) third geometric area in which the virtual control element 200 can generate feedback (in particular based on a response triggered according to a predetermined dependency) on an action by the user, initiated, implemented, not executable, not recommended and/or rejected referred to as feedback area 203. The position and/or size of the feedback area 203 (relative to the operating area 202 and/or relative to the display area 201) can be set, for example, depending on the vehicle data of the vehicle 100.

The feedback can be feedback that indicates a readiness to operate, a possibility of executing an operator action, a confirmation about an initiated and/or executed operator action, a recommendation and/or rejection regarding and/or feedback about a result of the execution of the Displays or represents operating actions.

The one or more display areas 201 and/or operating areas 202 and/or feedback areas 203 can each be at least partially spatially perceptible, in particular three-dimensional, areas. The operating area 202 can be a geometric area that triggers an operator action. This can be designed to carry out the operating action represented in the display area 201.

The varying of the one or more areas 201, 202, 203 can be a vehicle type-specific, vehicle-specific, application-specific and/or user-specific variation (e.g. valid for a period of use, except for a change) (dynamic adjustment and/or at least partially a setting that goes beyond a specific operating action ) be. The variation can be carried out in a user-specific, context-specific and/or driving situation-specific manner.

The varying is preferably carried out dynamically and/or depending on a parameter dependent on the vehicle 100. For example, the varying can be carried out depending on a parameter relating to the interior of the vehicle 100 (e.g. characterizing a further occupation of the user), characterizing an odometric size of the vehicle 100 and/or characterizing a driving situation of the vehicle 100. The parameter can be a predicted parameter (e.g. for the near future of a few milliseconds or seconds).

The variation can (possibly also) be done in a forward-looking manner, for example taking into account the parameter value (of the vehicle parameter) expected, in particular predicted, in a time interval in the near future. A corresponding function, a logic and/or a parameter according to which the variation is carried out can be changed.

• • verkleinert und/oder vergrößert wird;
• • verschoben, insbesondere in eine bestimmte Richtung verschoben, wird; und/oder
• • hinsichtlich seiner Form, insbesondere auf eine bestimmte Art und Weise, verändert wird.

In particular, the variation can take place in such a way that the operating area 202 in relation to the display area 201 and/or the feedback area of the operating element 200 in the vehicle 100:

• • is reduced in size and/or enlarged;
• • is moved, especially moved in a particular direction; and or
• • is changed in terms of its shape, especially in a certain way.

In one variant, the sensitive operating area 202 can be arranged at least partially (e.g. at least 10, 20, 30 or 50%) beyond the visualized display area 201. This can be implemented technologically (e.g. with a touchscreen) by different selection of the first geometric area with pixel lights to be controlled and the second area of the touch recognition to be read out.

The geometric areas 201, 202 mentioned can be or include spatial areas. For example, there can be or include different spatial areas 201, 202 in one or more three-dimensionally displayed virtual control elements 200 (e.g. in data glasses, a 3D display, e.g. in the instrument cluster or in a central display, or in a hologram). For example, it can be an operating element 200 that at least partially protrudes from the physical limits of a display device and/or is at least partially located within the physical limits of the display device. The area 202, which responds to virtual actuation (e.g. virtual pressing, tapping, sliding, turning, etc.), can be changed compared to the visualized area 201.

One or more visualized and/or sensitive areas 201, 202 can (also) be changed by one or more neighboring (virtual) control elements 200. As a result, accidental actuation of one or more adjacent control elements 200 can be prevented or made less likely.

The neighboring virtual elements 200 can optionally also be visibly changed. Preferably, the respective sensitive geometric area 202 (possibly invisible to the user) can be changed (only or predominantly). In this case too, the relationship between the visualized area 201 and the operating area 202 corresponding to it can be changed (adaptively).

For example, if it has been determined that a control element 200 has been actuated (with a comparatively high probability consciously or intentionally), the sensitivity of one or more of the neighboring control elements 200 (e.g. in relation to the respective visualized areas 201) can be temporarily changed.

• • dem Sitzplatz, von dem aus das Bedienelement 200 (zumindest voraussichtlich) bedient wird;
• • dem Winkel, aus dem die bedienende Hand des Nutzers kommt;
• • der Fahrzeugsitzeinstellung und/oder der Größe und/oder der Proportion der Person; und/oder
• • der Beschaffenheit des Fingers des Nutzers (z.B. Form, oder Breite der Berührungsfläche).

The variation can be done depending on:

• • the seat from which the control element 200 is (at least presumably) operated;
• • the angle from which the user's operating hand comes;
• • the vehicle seat adjustment and/or the height and/or proportion of the person; and or
• • the nature of the user's finger (e.g. shape or width of the contact surface).

• • der Ausführung der fahrerischen Tätigkeit (aktiv und/oder überwachend);
• • einer weiteren Beschäftigung und/oder einem Maß der Störung; und/oder
• • einer Blickrichtung und/oder Aufmerksamkeit in Bezug auf die Bedienaktion.

Alternatively or additionally, the variation can take place, depending on:

• • the execution of the driving activity (active and/or monitoring);
• • further employment and/or level of disruption; and or
• • a line of sight and/or attention in relation to the operating action.

Alternatively or additionally, the variation can take place depending on a current and/or predicted acceleration effect, in particular a lateral acceleration. This can be an acceleration acting on the passenger cell or on the user of the vehicle 100. For example, the acceleration can be determined using an acceleration sensor of the vehicle 100. Alternatively or additionally, the acceleration can be determined, for example, based on the course of the road, the lane, based on the driver's intention and/or on the basis of an at least partially automated and/or at least partially manually planned maneuver.

For example, a conclusion about the expected inaccuracy and/or deviation (e.g. a measure of the expected deviation and/or a measure of a specific deviation) can be made and taken into account. Inaccuracy can be inferred, for example, from a lack of attention and/or line of sight on the part of the occupant. In the case of the deviation, for example, a probable amount and/or a probable direction of the deviation can be determined and/or predicted.

In the context of the present document, the display of the control element 200 can (also) be understood as an acoustic and/or tactile, in particular haptic, perceptibility. For example, it can be a control element 200 that can be perceived by touch (e.g. tactile, tangible and/or associated with a specific tactile stimulus). The corresponding geometric area can correspond to the geometric area 201 in which the control element 200 is visually perceptible or can differ from it (e.g. according to a certain factor or according to a certain difference).

The varying of the sensitive geometric area 202 belonging to a virtual control element 200 can be varied in relation to the geometric area in which a virtual control element 200 is acoustically and/or tactilely perceptible. This can be done depending (e.g. according to a certain mathematical dependency) on a parameter of the vehicle 100, the driving situation, the context, etc.

The outputs determined for different perception channels of the user can therefore be varied with regard to their geometric areas (also dynamically and/or depending on one or more parameters described in the present document).

The varying can be done depending on the data from (a variety of) previous operations. In other words: if a user tries to hit a (relatively small) virtual control element 200 (e.g. in a right turn, left turn, during acceleration, braking, maneuvers, etc.... each from the driver's perspective or from the passenger's perspective), If the operating area 202 repeats, e.g. to the right, to the left, up, down, missed, then this can be taken into account automatically. For a subsequent input, the sensory field 202 can be changed (e.g. moved, in a certain direction, expanded, reduced, etc.) in relation to the visualization 201 of the control element 200. This can be done in such a way that the user is more likely to hit the changed operating area 200 with the following input.

For example, an unsatisfactory result of the operation (e.g. mistyped and then corrected) can be recognized. In particular, an accumulation of such events can be automatically recognized based on collected data, especially retrospectively. By precisely changing the first visualized geometric area 201 in relation to the second operation-sensitive area 202 and/or the feedback area 203, such events can then be avoided.

The adaptation can in particular be carried out in a person-specific, context-specific and/or driving situation-specific manner. For example, the frequency of certain deviation measures can be determined in a person-specific, context-specific and/or driving situation-specific manner and the second sensitive geometric area 202 can then be changed, in particular in relation to the corresponding visualized area 201.

The measure described in this document allows the precision and reliability of the operation of a display operating system 110 to be increased in an efficient manner. In particular, the probability of incorrect entries can be reduced. In addition, the driving safety of a vehicle 100 can be increased.

The present invention is not limited to the exemplary embodiments shown. In particular, it should be noted that the description and the figures are only intended to illustrate the principle of the proposed methods, devices and systems by way of example.
