Description

The present invention relates to a method and a device for interaction with an occupant of a vehicle according to the independent claims.It is known that it is extremely difficult to damage children in a vehicle during a trip, since the concentration of the driver is missing for an active distraction and passive distraction, for example due to hearing games, leads to long-standing drives, since they do not require any activity of the child.WO 2022 / 058143 A1, for example, describes a method and a device for providing information in a vehicle, which is configured to ascertain and also output personal data relating to an occupant.In contrast, DE 10 2021 111 109 A1 describes an environment-interactive system with augmented reality for infotainment and entertainment in the vehicle. Here, the infotainment system recognizes objects on the basis of images of a camera and the location of the vehicle and displays elements in the field of view of an occupant via a visual device on the basis of a location of an eye and the location of a body part.CN 114939272 A describes a head-up display-based interactive gaming system in which the head-up display is used for displaying game elements.The object of the present invention is to use as little effort as possible to occupants in the vehicle without requiring external hardware (such as game consoles, etc.) for this purpose.The object mentioned above is achieved by a method for interaction with an occupant of a vehicle, in which at least one object is detected in a surrounding area of the vehicle and at least one feature of the at least one object is determined. An item of information is output to the occupant based on the at least one feature.Object detection of at least one object in the environment of the vehicle thus takes place. The object detection can be based in particular on at least one sensor which measures the environment of the vehicle. This can be a camera, for example. Furthermore, a radar sensor and / or a LIDAR sensor can be used, which can also ascertain depth information. At least one object, preferably all objects located in the direct environment of the vehicle, and their positions are thus detected. The object can be, for example, a building, a person or an animal. The at least one feature of a detected object may be a color of the object and / or a position and / or a size of the object.The output of the feature to the occupant is preferably purely acoustic, and more specifically most preferably via the corresponding loudspeakers of the interior of the vehicle, so that above all no further components, such as external hardware, are necessary. Preferably, no pictorial output of the features of an object or recognized objects takes place. The determined features or information about recognized objects are therefore not output on a re-input unit, for example a screen, in the vehicle.Information can be understood to mean, in particular, a question. The method comprises, in particular, making a question to the occupant based on the at least one feature. An indication of the position of the object can also be given. For example, it is possible to request where an object with a specific color is located or which color a specific object has. Furthermore, traffic situations can be derived and questions corresponding to the occupant can be asked. For example, the occupant may be asked where to bend. This can be derived on the basis of recognized traffic signs. An object can thus likewise be a road sign, wherein a question can be asked on the basis of a traffic rule associated with the road sign.For example, a field of view of the occupant may be considered that may be previously detected by a sensor. The sensor can be, for example, a camera which is arranged in the interior of the vehicle and can determine an exact position, preferably also an eye position, of the occupant and a size of the occupant. The field of view can also be significantly influenced above all by the size of the occupant, since, for example, smaller occupants, such as children, can only recognize the horizontal plane of the environment to a limited extent by their size in relation to the lower window frame.Furthermore, the method can take into account a direction of travel of the vehicle and / or a speed of travel. Taking into account the above-mentioned parameters, the method can ask a question, for example where the corresponding object is located or which object has a specific feature. In this case, by taking into account the above-mentioned parameters, it can be ensured that the object can be recognized by the occupant. Furthermore, the method can provide, for example, a plurality of response options. Overall, the method can thus provide an active interaction possibility or entertainment possibility, in particular a game. In particular, the corresponding method uses the ID coin of the vehicle as a joystick, in other words as the interaction possibility of the occupant with respect to the output information, for example the question. The ID coin is to be understood above all as an electronic key of the vehicle and is thus always available during a trip. Thus, a direct response possibility can be given via the ID coin without requiring external hardware. Further, the ID coin may be used to start and / or end the output of the information, and thus the entertainment function. It is also possible, for example, to proceed to a next question.Occupants, in particular children, can thus be engaged in without the driver having to take care of an active distraction, so that the driver can continue to devote his complete attention to road traffic. In this case, the occupants are actively bound in, so that their attention is promoted and no longfall occurs.In a further aspect, the invention relates to a device for interaction with an occupant of a vehicle, which device comprises a sensor for detecting at least one object in a surrounding area of the vehicle and an evaluation unit for determining at least one feature of the at least one object. The apparatus is configured to output information to the occupant based on the at least one feature. This is preferably done via an output unit, especially a loudspeaker. For this purpose, the device can also have a control unit which is designed to actuate a corresponding output unit, in particular a loudspeaker, on the basis of the results of the evaluation unit. In a further aspect, the invention relates to a vehicle comprising a corresponding device.They show in purely schematic representation: FIG. 1 : shows a method diagram of a method for interaction with an occupant of a vehicle; and FIG. 2 : shows a device for interaction with an occupant of a vehicleFIG. 1 shows a method diagram of a method 100 for interaction with an occupant of a vehicle, which method comprises a detection 101 of at least one object in a surrounding area of the vehicle. Furthermore, the method 100 comprises a determination 102 of at least one feature of the at least one object. An output 106 of information to the occupant is carried out on the basis of the at least one feature. The output is preferably purely acoustic 106 a. In particular, the occupant is asked 106 b. Furthermore, indications about the position of the object can be given 106 c. This can be done 104 in consideration of the occupant's field of view, which can be determined 103 in advance. A driving direction and / or a driving speed can also be taken into account 105. The ID coin of the vehicle is used 107 as joystick.FIG. 2 shows a device 10 for interaction with an occupant of a vehicle, which device comprises a sensor 11 for detecting at least one object in the surroundings of the vehicle and an evaluation unit 12 for determining at least one feature of the at least one object. Furthermore, the device may comprise a control unit 13 which controls the corresponding output via corresponding output units 14, preferably loudspeakers 15. The device can also comprise an ID coin 16 which serves as a joystick and thus, for example, for feedback of a response as an interaction possibility.List of reference characters100 Method for interaction with an occupant of a vehicle 101, detection of at least one object in a surrounding area of the vehicle 102, determination of at least one feature of the at least one object 103, determination of the field of view of the occupant 104, consideration of the field of view of the occupant by a sensor 105, consideration of a direction of travel and / or a speed of travel 106, output of information to the occupant based on the at least one feature 106a purely acoustic output 106b, question 106c, giving an indication of the position of the object 107, use of an ID coin of the vehicle as joystick 10 device for interaction with an occupant of a vehicle 11 sensor 12 evaluation unit 13 control unit 14 output unit 15 loudspeaker 16 ID coinReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
