Description

The present invention relates to the control of an entertainment system on board a vehicle. In particular, the invention relates to an improved user-oriented control of such an entertainment system.

A motor vehicle includes an entertainment system configured to play a piece of entertainment in the interior of the motor vehicle. A person on board the vehicle, such as a driver, can select a piece of entertainment to play from a library. The library can be provided on board the motor vehicle, or a remote service can be used that includes the library. Typically, a profile is created at the library based on the user's listening habits so that a recommendation for a piece of entertainment to play can be provided. The profile typically does not contain any information about the situation or context in which the user decided to play a particular piece of entertainment.

An inappropriate suggestion for a piece of entertainment can be perceived as particularly aversive by the person on board the vehicle. If there are several people on board the motor vehicle, they may have varying levels of agreement with the piece of entertainment that is being played. The passengers are in a relatively small space during the journey, so it is difficult for a passenger to avoid a piece of entertainment. A driver must concentrate on driving the motor vehicle and should at best be motivated by the playing of a piece of entertainment, but under no circumstances should they be distracted or made aggressive. Special conditions therefore apply to the playing of a piece of entertainment on board a motor vehicle, which can affect not only the well-being of a person on board the motor vehicle, but also driving safety if the playback concerns a driver of the motor vehicle.

An object underlying the present invention is to provide an improved technique for determining a recommendation of an entertainment item on board a vehicle. The invention solves this problem by means of the subject matter of the independent claims. Subclaims give preferred embodiments.

A method according to the invention for determining a recommendation for the playback of an entertainment item on board a vehicle comprises steps of detecting a person on board the vehicle; determining a social situation in which the person on board is; and determining the entertainment item on the basis of the social situation.

It has been recognized that the particular conditions applicable on board the vehicle for selecting a recommendation to play a piece of entertainment can advantageously be determined on the basis of sensing by sensors already present on board a typical vehicle. The recommendation may include a suggestion to play a specific content on board or to skip or suppress a predetermined content. For example, content with explicit content may be prevented from being played if there is a child on board. This may also apply if the content has been manually selected by a person on board. Conversely, the selection of content aimed at children may be suppressed if it has been determined that only business travelers are on board.

For example, the conditions may be determined based on a seating position of a passenger's seat, acoustic or visual conditions, climate control, or other user-controlled functions. Information about a geographical position, a planned route, or a navigation destination may also be used. Thus, the entertainment item can be determined to better suit the social situation of the person. The person may be better entertained or assisted in an activity on board the vehicle. The activity may particularly concern driving the vehicle if the person is a driver of the vehicle. The entertainment item can be selected to have an increased entertainment value. The entertainment item can better entertain, match the social situation on board, or the mood of one of the passengers.

The entertainment item preferably comprises a music track, a video data stream or a digital content. For example, the entertainment item may comprise a podcast, an audio book, a feature film, a TV show or a video clip, for example from an external platform for providing such content. The suggestion may also relate to a current program, for example radio or television. The music track may be played using a general or personal audio system on board the vehicle. The video data stream may be played on a projector, a monitor or a display on board the vehicle. The display is not necessarily visible to all persons on board the vehicle. In one embodiment output is made on the person's personal device, such as a smartphone. An acoustic part of the video data stream can be output via an audio system.

Digital content can include, for example, a game, a program or an app that can be processed using an on-board processing device. The digital content can also include a combination of a music track with an interaction, for example in the style of a karaoke track or a sing-along version of the piece of music. The age of the person can be taken into account in particular when determining digital content. If there are several people on board the vehicle, the age of the youngest passenger can be decisive for the selection.

The systems mentioned can be used on board the vehicle to output an optical or acoustic part. The digital content can be interactive and an input device, a sensor or an arrangement of different sensors can be provided on board the vehicle with which the person can make an input or with which an input can be scanned by the person. The input device and the output device can be combined with one another, for example in a touch-sensitive screen (touchscreen). A mobile phone or a similar device that is assigned to the person can be used as an input device and/or as an output device. A projector or a microphone can also be used. In one embodiment, data glasses or a similar output device are used that can allow real and generated content to be superimposed in order to convey an artificial reality (virtual reality), an improved reality (augmented reality) or a mixed reality to the user.

Various techniques are presented for determining the social situation on board the vehicle, which can also be combined with one another. For example, the social situation can be determined on the basis of a formal situation on board the vehicle. The formal situation can in particular relate to the original purpose, namely the transport of at least one person by means of the vehicle from a starting point to a destination. The formal situation can thus include the starting point, the destination, the reason for the journey, a journey time so far, a journey time remaining, a current date, a current time, a number of passengers or their distribution in the vehicle or a configuration of the vehicle. The configuration can be open or closed in a convertible and, for example, sporty or economical in another vehicle. For example, on a journey to work, a more reserved or sober piece of entertainment can be recommended for playback, while on a journey to a vacation, a more cheerful or relaxing piece of entertainment can be selected.

The formal situation may also include the number of people present, their age, social status in relation to a driver (e.g. colleague or family member), or place of entry into the vehicle (at home, at work, at a company address, etc.).

The social situation can be determined on the basis of an activity of the person. The selection of the entertainment item can take the person's activity into account and support it where necessary. For example, the person can be busy driving the vehicle. In other examples, the person can be talking to another person, determining a route for the vehicle, eating or sleeping. Different activities can also be carried out in combination with one another. A driver who is eating and talking at the same time is unlikely to be interested in a complex entertainment item. It is also possible, for example, to refrain from suggesting an entertainment item with very loud, very fast or very dynamic passages if a person wants to sleep on board. Conversely, a driver of the vehicle can be prevented from falling asleep by avoiding entertainment items with uniform output or monotonous passages.

In particular, when a person on board is controlling the vehicle, i.e. is the driver of the vehicle, the social situation can advantageously be determined on the basis of a driving state of the vehicle. The driving state can include, for example, a driving speed, a road class of a busy road or a traffic density of traffic on the busy road. Furthermore, the driving state can include weather, a time of year, the condition of a driving surface or a curvature of the driving road. The driving state can also be related to the driver and include, for example, tiredness, a level of exertion or a required level of attention of the driver. In particular, it can be dynamically taken into account that driving the vehicle places dynamic demands on the driver and that the driver can be supported in his task of driving the vehicle by a suitable dynamic selection of a piece of entertainment.

Conversely, a selection of suggestions can also be made to encourage a certain behavior on the part of the driver. For example, the driver can be calmed down by calm content in a demanding traffic situation such as a traffic jam, or kept focused with interesting content on a long journey. Vehicle consumption can be reduced by encouraging the driver to drive in a consistent manner.

If there are several people on board the vehicle, a social situation can be determined for each person, whereby the entertainment can be determined on the basis of the specific social situations.

In this embodiment, it can be taken into account that social situations of several people on board the vehicle can differ significantly from one another. By combining the social situations of several people, a piece of entertainment can be determined that is tailored to the combination of social situations. To determine an individual social situation, for example, a degree of tiredness, a degree of exertion, a past or upcoming appointment of the person or a significant event in the person's life can be determined.

A person can be recognized so that other, already available information can be associated with them. The person can be recognized in the vehicle, for example, using a biometric sensor, through an individual input, via a device assigned to them such as a smartphone, or by optical recognition. The person can also be recognized before getting in, for example because they are carrying a predetermined token that can be used to control the vehicle, or because a suitable sensor for the person or their device is provided on the outside of the vehicle.

For this purpose, the person can be optically scanned using an interior camera, for example, or personal information can be evaluated, which is stored, for example, in the person's calendar or in a personal electronic device carried, in particular a smartphone. It should be noted that the combination of the social situations of the individual people on board the vehicle cannot necessarily be carried out on an equal basis, but that social dependencies between the people can be taken into account when combining.

For several people on board the vehicle, a common social situation in which the people find themselves can be determined. The piece of entertainment can then be determined on the basis of the common social situation. For example, on the basis of a visual and/or acoustic scan of the people on board, it can be determined whether the mood on board the vehicle is more cheerful, communicative, silent, depressed, concentrated or ominous. For example, it can be relatively easily determined on the basis of acoustic scans whether two people are arguing, talking or silent. In another example, it can be determined that there is a small child on board who is, for example, being fed, sleeping or crying. The common social situation can also be taken into account in addition to one or more individual social situations of people on board the vehicle.

A personal or shared social situation can be determined on the basis of a social constellation of people on board the vehicle. For example, it can be determined whether a person takes on the role of a child, a partner, a superior, an employee, a family member or a guest of another person on board the vehicle. In one embodiment, a directed social relationship between people on board the vehicle can be determined. For this purpose, a predetermined social scale can be created for the people. In general, a one- or multi-dimensional social model can be determined between people in the vehicle. This can include one or more dimensions in which two people form a directed relationship. Example dimensions include age, a professional connection, a friendship, an acquaintance, for example via a social medium or a club, an educational relationship or whether one of the people is a driver or a passenger. Another relationship can, for example, relate to how often or how long a person travels in the vehicle.

In addition, the age structure of the people can be taken into account. By taking the social constellation into account, both the determination of the common social situation and the combination of individual social situations can be improved so that the prevailing social conditions on board the vehicle can be understood and taken into account in the choice of entertainment. If, for example, there is an underage child on board, a suggestion for entertainment with explicit language may be prevented. This rule can take precedence over another method of determination.

To determine the entertainment item, a person's personal preference can also be taken into account. The personal preference can in particular relate to a profile of the person that reflects their consumption habits for entertainment items. The profile can be created on the basis of a personal selection, a frequency of playing certain items, a search for certain content or genres. A demographic assessment of the person or their preferences can also be made. This can determine which preferences are usually held by people who are similar to the person in question, for example in terms of gender or age. The person's personal preferences can be held by an external service, for example an external provider of entertainment items.

It is also preferred that a personal preference for entertainment is determined for several people on board the vehicle. The suggested entertainment can be determined on the basis of the specific personal preferences of the several people. To do this, the people's preferences or profiles can be superimposed, combined or mixed. The social constellation of the people can be taken into account for such a combination. It is also preferred that the preferences are interpreted depending on the social situation. This makes it possible to take into account in an improved way that certain preferences of a user depend on a certain social situation. The social situation can in particular include the presence of other people.

Acceptance of a person on board the vehicle for a particular piece of entertainment may be tracked to provide improved, accurate recommendations. In one embodiment, a first piece of entertainment is determined and a response of a person on board the vehicle to the particular piece of entertainment is detected. Determining a second piece of entertainment may be done based on the detected response.

The reaction can include an active input or assessment by the person using an input device. The reaction can alternatively or additionally be derived from a behavior of the person, which can be recorded, for example, using an interior camera. If the person uses an input device, they can provide their reaction to the suggestion in an improved manner before the suggestion is carried out and the entertainment piece is played on board the vehicle, or later when the suggestion is already being played. It is also possible to observe which entertainment piece a person chooses after a suggestion for an entertainment piece has been rejected. These measures can improve the learning of the person's preferences quickly and accurately. Learning can take place with regard to a person or a group of people. Specific or learned preferences can be stored on board the vehicle or in a central location. These observations can be particularly informative if there are several people on board the vehicle who show different reactions to a suggested entertainment piece. A reaction can include, for example, singing along or moving rhythmically.

If several people are recorded on board the vehicle, the people can be assigned to a group of people. The entertainment item can then be determined based on a group preference of the group of people. A group preference of the group can be learned or created. A group preference can be developed over time based on observation of the entertainment items consumed, so that a group that stays on board the vehicle more often or for longer can be better assessed.

Such a group can be a family or a work group. In one embodiment, groups of people can be determined based on a place of entry or exit. For example, groups of people can be determined for a common route to school, a route to work, a route to or from a sporting event or a dance class. Of course, different groups with their respective group preferences can be taken into account. It can also be taken into account that a predetermined group does not necessarily have to be fully on board the vehicle or that the group can be supplemented by one or more people. Preferences of a group of people can be given a higher weighting if all the people assigned to it are present, and a lower weighting if more of the people are missing.

A social situation, context or relationship between individuals or groups of people in a vehicle and their preferences in these contexts are typically not known, not stored and not determined by observation in external services. In another variant of the presented technique, this function can be accomplished by a dedicated data storage and learning unit. The storage and/or learning could then take place in the vehicle, on a user device or in a cloud-based system.

Optionally, groups of people can also be formed that are isolated from each other when recording a piece of entertainment. For example, zones can be formed within the vehicle in which different pieces of entertainment can be played that do not concern a person in another zone. People in different zones can be in different social situations. The determination of a suggestion described here can relate to only one of the zones or the people in the zone. Of course, the determination described can also be carried out for several zones independently of each other. Example zones include a first, second and third row of seats in the vehicle. A zone can be predetermined or formed dynamically based on a scan of the interior.

The system can be set up to automatically create/suggest groups of people within the vehicle, for example based on their social situation, context, interests, etc. The system can also learn which division of people into groups is preferred for a certain number of people in the vehicle. For example, on a long journey, children can enjoy an entertainment program together in a rear row of seats, while adults listen to music in a front row of seats. The system can create a first group with the children and a second group with the adults. Each group can be assigned a spatial extent on board the vehicle. This extent can be called a zone. If the context of a long journey with the described occupation is determined, a division into the groups or zones mentioned can be suggested. Adapted suggestions for a piece of entertainment can be determined for each group.

In one embodiment, a person on board who does not participate in a reception of the proposed entertainment item is determined, whereby the group of people does not include this person. For example, it can be taken into account when a person is engaged in another activity, for example when sleeping, or when wearing headphones to consume other entertainment items, play a game or talk to a distant person. The person can also be in a different acoustic zone than a driver on board the vehicle. If there are people on board the vehicle who only partially, but not exactly, form a predetermined group of people, another predetermined group of people can be determined that includes as closely as possible the people who are present on board the vehicle. The entertainment item can then be determined on the basis of a group preference for entertainment items that is assigned to this group of people. The group preference can be determined on the basis of an observed behavior of the group or content consumed in the past.

This approach can be particularly advantageous if there is a person on board who cannot be identified or about whom no background information is known.

It can also be determined that there are people on board the vehicle who are members of different predetermined groups of people, with each group of people being assigned a group preference. The suggestion can be determined on the basis of a group preference that is assigned to each of these groups of people. In this way, group information can be taken into account even if no such group of people is known for the constellation of people on board the vehicle. For example, a first predetermined group can include a family and a second predetermined group a work group, with at least one person being known who is a member of both groups. In this way, a preference for an entertainment item can also be transported between different groups if both groups include at least one person in common. Entertainment items can thus be selected from an improved, richer pool.

A system according to the invention for determining a recommendation for playing an entertainment item on board a vehicle comprises a sensing device for detecting a person on board the vehicle; a device for determining a social situation in which the person on board is; and a device for determining the entertainment item on the basis of the determined social situation.

The device can in particular comprise a processing device, which is preferably implemented electronically and can in particular comprise a programmable microcomputer or microcontroller. The processing device can be set up to partially or completely carry out a method described herein. The method can be in the form of a computer program product with program code means. The computer program product can be stored on a computer-readable data carrier. Features or advantages of the method can be transferred to the system and vice versa.

A vehicle according to the invention comprises at least a part of a system described herein. A part of the system can also be mounted outside the vehicle and connected to the vehicle by means of a wireless communication link.

1 shows a system 100 on board a vehicle 105. The system 100 is configured to determine a piece of entertainment for playback on board the vehicle 105 in an improved manner.

On board the vehicle 105 there is at least one person 110. The person may be a driver of the vehicle 105. In the representation of 1 For example, two people 110 are provided, one of whom is shown on the left as a driver and one of whom is shown on the right as a passenger. It is also possible that none of the people 110 is actively driving the vehicle 105. If several people 110 are present on board the vehicle 105, they can form a group of people 115.

The system 100 on board the vehicle 105 comprises a processing device 120, which can be coupled to a device on board the vehicle 105 by means of an interface 125. The system 100 can communicate with a personal electronic device that can be assigned to one of the persons 110 on board the vehicle 105 via the interface 125 or a further interface. A first sensor 130 for scanning an interior of the vehicle 105 and/or a second sensor 135 for scanning an environment of the vehicle 105 are further preferably provided. The sensors 130, 135 can each comprise a camera, a stereo camera or a depth camera, for example. Further options for the sensors 130, 135 include a radar sensor, a lidar sensor or an ultrasonic sensor. The first sensor 130 can also comprise an acoustic sensor such as a microphone. A state of a user-controlled device such as a seat adjustment, an air conditioning system of the interior or an interior lighting setting can also be detected by means of the first sensor 130. The first sensor 130 can also comprise, for example, a seat occupancy sensor, a door contact or a belt sensor. Several sensors 130 can be used to determine a predetermined situation by means of sensor fusion. Even if a person 110 cannot be identified in this way, it may be possible to determine their presence.

Optionally, the system 100 also includes an entertainment system for providing a predetermined piece of entertainment on board the vehicle 105. For this purpose, the system 100 can include a data storage 140 for storing pieces of entertainment, an acoustic output device 145 and/or an optical output device 150. Optionally, a data storage 140 can also be used in a coupled device on board the vehicle 105, for example a smartphone that is assigned to a person 110. The piece of entertainment can, for example, include a piece of music that can be output to all persons 110 on board the vehicle 105 by means of the acoustic output device 145. Additional information, for example an artist or a title, can be provided on the optical output device 150.

In a similar way, a video data stream can also be provided to the persons 110 by means of the optical output device 150 and/or the acoustic output device 145 on board the vehicle 105. Digital content, for example an app or a game, can run on the processing device 120 and be provided in the manner mentioned to one or more persons 110 on board the vehicle 105. An input device 155 can also be provided, via which a person 110 can provide an active input to the system 100. The input device 155 is exemplified as a touch-sensitive screen in combination with the output device 150. Other input devices are also possible.

Optionally, a communication device 160 is provided which is designed to communicate with at least one external location. In 1 A first external location 165 and a second external location 170 are shown as examples. The first external location 165 is set up to receive and process information that was recorded on board the vehicle 105. On the basis of the information, a piece of entertainment can be determined and a reference to the piece of entertainment or the piece of entertainment itself can be transmitted back to the vehicle 105.

The second external location 170 can, for example, comprise a music service, a streaming service or a social network that is set up to provide pieces of entertainment. For this purpose, a person 110 can have a user account at the second external location 170, which they use when downloading pieces of entertainment from there. The second external location 170 can create a profile of preferences or usage behavior of the person 110. The profile or the preferences can be obtained via the communication device 160. Access can alternatively be made from the system 100 or from the first external location 165. A piece of entertainment to be issued on board the vehicle 105 can also be obtained from the second external location 170. A list of available services can be present on board the vehicle 105, from which the first external location 165 and/or the second external location 170 can be determined.

2 shows an exemplary determination of a suggestion for an entertainment piece for several people 110 on board a vehicle 105. A first person 205, a second person 210 and a third person 215 are shown purely as an example. Together, the people 205 to 215 form a predetermined group of people 115.

A social constellation can apply between persons 205 to 215, which can be defined by social relationships or interactions between persons 205 to 215. The social constellation can, for example, express a directed social relation, such as a social relationship between a supervisor and an employee, a parent and a child, or a driver (as a service provider) and a passenger. The constellation can also express another social relation, for example a partnership relationship or a general lack of social relationships.

The constellation can be determined from knowledge of a formal or personal position of a person 205 to 215. To do this, the system 100 can obtain corresponding information, for example from a central location or from a personal device of the person 205 to 215. The vehicle 105 or its manufacturer may already have information about a person 110 and use it accordingly. A dynamic social position of a person 110, for example depending on an occasion, can be determined based on an entry in a calendar of one of the people 205 to 215. For example, it can be determined that the first person 205 generally has a superior position to a second person 210, but that when traveling to a school graduation party of the second person 210, the latter must be considered more important than the first person.

Each of the persons 205 to 215 is in a personal social situation 220 that is in an upper range of 2 are visualized as circles. The personal social situations 220 of the persons 205 to 215 may partially overlap each other. There may be an area that is contained in each of the personal social situations 220. Such an area is in 2 colored dark as an example. In addition, the three persons 205 to 215 are in a common social situation 225, which surrounds the personal situations 220 in the form of a circle.

In a lower range of 2 For each of the persons 205 to 215, a personal preference 230 is shown in the form of a circle. The preference 230 symbolizes entertainment pieces that the assigned person 205 to 215 rates as good or pleasant or otherwise positive. Personal preferences 230 can be individually determined on the basis of consumption habits of the assigned persons 205 to 215. In addition, actions of the persons 205 to 215, for example searching for an artist, an entertainment piece or a genre, can be used to create the personal preferences 230. Personal preferences 230 of the different persons 205 to 215 can partially overlap each other, as shown by a dark area in 2 is indicated.

A group preference 235 is symbolized by another circle and reflects a kind of consensus of the people 205 to 215 of the group of people 115 regarding their respective personal preferences 230. The group preference 235 can be formed by combinations of the personal preferences 230, preferably taking into account the social constellation of the people 205 to 215. In particular, a weighting can be determined via the constellation and the personal preferences 235 can be superimposed on one another or combined with one another. In this case, figuratively speaking, a superset, an intersection or an intermediate set of preferences can be determined as the group preference 235.

It should be noted that the constellation can also change, for example if one person 110 initially acts as the driver and later alternates with another person 110. A weighting can also be determined based on the positions of the persons 110 on board the vehicle 105. For example, It may be considered that a person 110 in the first row of seats may assist a driver, for example with navigation, or that a person 110 in a second or third row of seats is usually less likely to participate in a conversation further forward. An increased distance of a person 110 from the driver may lead to a weaker weighting. A degree of participation of a person in a joint communication or in the reception of a piece of conversation may also be used for weighting.

Based on the personal social situations 220, the common social situation 225 and the personal preferences 230 of the individual persons 205 to 215, a suggestion 240 for an entertainment piece can be provided. Both a combination of the social situations 220, 225 with one another and a combination of preferences 230 can each be made depending on a social constellation between the persons 205 to 215. Optionally, several suggestions 240 can be determined from which persons 110 can vote or choose. The suggestions can differ in a predetermined way, for example a conservative suggestion 240, a progressive suggestion 240 and a calm suggestion 240 can be provided.

For example, it can be determined that the first person 205 should be assumed, for example because he or she is a driver of the vehicle 105, and his or her social situation 220, 225 and his or her preferences 230 should be assumed. Social situations 220 and preferences 230 of the other persons 210, 215 can nevertheless be taken into account when determining the suggestion 240. In a continuation of a suggestion 240, a setting can also be determined that relates to a system in the interior of the vehicle 105 and affects the person 110, for example air conditioning, seat adjustment or interior lighting. This setting can be activated automatically or provided to the person 110 in advance for confirmation or rejection.

In a further embodiment, a social situation 220 and/or a preference 230 can also be assigned to the group of people 115. The group of people 115 can essentially be viewed as an individual person 110. Their preferences 230 can be created, for example, on the basis of search terms, reproduced entertainment pieces or reactions of one of their members 205 to 215 to a suggestion 240. The social situation 220 of the group of people 115 can either be understood as a personal social situation 220 of the group of people 115 or can be created in the manner described from personal social situations 220 and optionally a common social situation 225. The social constellation between the people 205 to 215 can be taken into account.

3 shows a flowchart of a method 300 for determining a suggestion 240 for an entertainment item on board a vehicle 105.

In a step 305, an interior of the vehicle 105 can be scanned. In a step 310, at least one person 110 on board the vehicle 105 can be detected on the basis of the scan. The scan can be sufficiently accurate to determine, for example, a posture or facial expression of the person 110. The person 110 can be identified on the basis of biometric features. It can also be determined whether a person 110 is on board whose identity is unknown. Nevertheless, the person 110 can be recognized under certain circumstances, for example because he or she took part in a previous trip with the vehicle 105.

In a step 315, a personal preference 230 of a specific person 110 on board the vehicle 105 can be determined. For this purpose, a request can be made to the second external location 170.

On the basis of the recorded persons 110, a group of persons 115 can be determined in a step 320, which can be known as an entity. Optionally, a new group of persons 115 can be created. If the composition of the persons 110 recorded on board only inaccurately corresponds to a known group of persons 115, this group of persons 115 can be used as a basis or a new group of persons 115 can be created on its basis.

In a step 325, a group preference 235 of the group of people 115 can be determined. The group preference 235 can also be determined on the basis of the personal preferences 230 of its members 110. It should be noted that the combination of preferences 230, 235 can be based on a social constellation of the people 110 on board the vehicle 105.

On the basis of the recorded persons 110 on board the vehicle 105, a personal social situation 220 of the person 110 can be determined in a step 330. If there are several persons on board the vehicle 105, several personal social situations 220 can be determined accordingly. In a step 335, a social situation 225 common to the persons 110 can be determined. This determination can be based on external information, for example regarding formal information relating to the transport of the persons 110 in the vehicle 105. Such information can relate to a starting point, a destination, an occasion or a travel duration. The common social situation 225 can also be determined from a combination of the personal social situations 220 of several persons 110 on board the vehicle 105. Here too, the combination of social situations 220, 225 can be based on a social constellation of the persons 110 on board the vehicle 105.

In a step 350, an environment of the vehicle 105 can be scanned. In a step 355, a driving state of the vehicle 105 can be determined. This information can also be used elsewhere, for example as formal information regarding the journey with the vehicle 105.

In a step 360, a suggestion 240 for a piece of entertainment can be provided that can be played or output on board the vehicle 105. The suggestion 240 can be determined on the basis of the specific preferences 230, 235, the social situation 220, 225 and/or the driving state. The suggestion 240 can be provided in textual or graphical form, for example. Optionally, the suggestion 240 can be implemented by obtaining a corresponding piece of entertainment and outputting it by means of an output device 145, 150 on board the vehicle 105.

A reaction of a person 110 to the provided suggestion 240 can be determined either on the basis of an input provided by the person or the scanning of the interior in step 305. Based on the reaction, it can be determined whether the suggestion 240 is perceived as acceptable or unpleasant for this person 110. This information can be used to provide a further suggestion 240. In addition, the group preference 235 or, if only one person 110 is on board the vehicle 105, a personal preference 230 of the person 110 can be adjusted accordingly.

4 shows a data processing 400 for providing a suggestion 240 for an entertainment item on board a vehicle 105. The data processing 400 can be implemented both by a system 100 and by a method 400.

In a step 405, events or attributes of a consumption of digital content in the sense of a piece of entertainment can be determined. For this purpose, in a step 410, one or more people 110 who are on board the vehicle 105 can be determined. For a person 110, a role can be determined that they take on board the vehicle 105, for example that of a driver, a passenger or a navigator. A social constellation between several people 110 can also be determined. For example, a person 110 can take on a predetermined role such as father, mother or child in a family, which can be known as a group of people 115. Other example constellations between two people 110 include a partnership, or supervisor and employee or equal colleagues. A person 110 can also be a passenger or person of respect, for example. The identity and/or role of a person 110 can also be specified by input, for example in a textual or verbal dialogue.

In a step 415, a context in which digital media is consumed can be determined. The context can be determined based on a scan of an interior or surroundings of the vehicle 105. Further information can be obtained from the vehicle 105 or a device of one of the people 110. The context can include, for example, a date, a day of the week, a starting location, a destination, a driving mode or a driving state of the vehicle 105, settings of an air conditioning system (HVAC: heating, ventilation, air conditioning), communication between people 110 on board or a detected mood or emotion on board.

In a step 420, one or more personal devices of persons 110 on board can be determined. Such a device can in particular comprise a tablet computer, a laptop computer or a smartphone and can be assigned to a person 110 on board. Personal information about the person 110 can be stored on the device or made accessible. For example, an appointment calendar of a person 110, a personal preference 230 or access information for retrieving a personal preference 230 can be retrieved from an external location 170 via the device. The device can be used to determine a social situation of a person 110 more precisely, for example by analyzing social messages that can influence a mood or situation of the person 110. The device can be connected wirelessly to the vehicle 105 or the system 100. The person 110 can control which information should be read out by the system 100 and which should not.

In a step 425, preferences 230 or profiles of the persons 110 can be determined. For this purpose, in a step 430, corresponding information can be retrieved from the external location 170 if the person 110 is known and has given their consent for a retrieval. If the person 110 is not known or has refused to retrieve preferences 230, these can be created by observation in a step 435.

If preferences 230 are present, they can be combined with one another in a step 440. For this purpose, a social constellation between persons 110 to whom the preferences 230 are assigned can be taken into account. In a step 445, preferences 230 of a person 110 can be expanded or adapted. For example, it can be noted which piece of entertainment a person 110 has consumed and under which circumstances or in which context. In a step 450, the provision of a suggestion 240 can be controlled. Steps 445 and 450 can also be carried out if no preference 230 was initially present.

Based on the control in step 450 and the preferences adjusted, if any, in step 445, one or more recommendations for a digital content or piece of entertainment may be provided in a step 455. A response from one of the persons 110 on board may be detected and the response may be used to adjust one or more preferences 230 of persons 110. It should be noted that a preference may have both a positive and a negative effect. For example, a certain type of music may be increased or another may be decreased as a suggestion 240.
