It is a schematic diagram which shows the example of an age category database. It is a schematic diagram which shows the content of the presentation permission / denial database.

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  FIG. 1 is a schematic diagram showing a configuration of a system 1000 according to an embodiment of the present invention. This system 1000 is mounted on a vehicle such as an automobile. As shown in FIG. 1, the system 1000 includes a microphone 100, a camera 200, a display 300, a speaker 310, a CAN (Controller Area Network) 400, and a control device (information presentation device) 500.

  The microphone 100, the camera 200, the display 300, and the speaker 310 are disposed in the vehicle interior. The microphone 100 acquires indoor sound, mainly occupant's sound. A plurality of microphones 100 may be provided in the room. The camera 200 includes a visible light camera, an infrared camera, and the like, and mainly captures the occupant's face. The display 300 is disposed at a position where an occupant in the room can visually recognize, displays information to the occupant by displaying information, and inputs information using a touch panel. The speaker 310 is disposed in the room and presents information to the passenger by voice.

  The control device 500 includes a presentation information determination unit 510, a presentee identification unit 520, an exception processing unit 530, an age estimation unit 540, an age category determination unit 550, an age restriction setting unit 552, an age category database 554, a presentation permission determination unit 560. , Presentation permission / denial database 562, vehicle margin calculation unit 564, vehicle information acquisition unit 566, presentation information change unit 570, information change amount determination unit 572, simple expression database 573, cognitive physiological characteristic database 574, information comprehension calculation A unit 576, a gender estimation unit 578, a reaction acquisition unit 579, and an information presentation unit 580.

  The exception processing unit 530 includes a personal authentication unit 532, an age determination exception determination unit 534, and an age determination exception database 536. Each component of the control device 500 shown in FIG. 1 includes a circuit (hardware) or a central processing unit such as a CPU and a program (software) for causing it to function.

  The system 1000 can communicate with an external server 600. As a communication method, for example, a method such as Bluetooth (registered trademark), WiFi, 4G, or the like can be used. Note that the communication method is not particularly limited.

  The data accumulated in the database such as the age determination exception database 536, the age category database 554, the presentation permission / non-permission database 562, the simple expression database 573, and the cognitive physiological characteristics database 574 provided in the system 1000 communicate with the external server 600. It may be downloaded from the server 600 by performing.

  The data stored in these databases may be held on the server 600 (cloud) side. In that case, the system 1000 accesses the server 600 to acquire data when using the data.

  In the present embodiment, when various types of information are presented from the vehicle to the occupant by the system 1000 configured as described above, the age of the information presenter is estimated based on information acquired by the camera 200 and the microphone 100. Then, information is presented according to the age of the information presenter. In the present embodiment, by performing such processing, it is possible to realize optimum information presentation according to age.

  Various information can be given as examples of information to be presented. As an example, the information to be presented includes an answer to a question from an occupant, information that prompts the driver to take a break, information that indicates the occurrence of a vehicle failure, and the like. Moreover, as will be described later, collision prediction information, restaurant information, entertainment information, liquor store information, and the like can be presented. Thus, the information to be presented is not particularly limited. The entertainment information is information relating to entertainment, distractions, and the like.

  Examples of the information presentation method include screen output by display on the display 300, sound output by the speaker 310, application of vibration to a seat or the like on which an occupant is seated, smell, change in texture, and the like. The method for presenting information is not particularly limited.

  FIG. 2 is a flowchart showing processing performed by the control device 500. First, in step S10, information in the age determination exception database 536 is acquired. In the next step S12, it is determined whether there is information to be presented to the occupant from the vehicle. When there is information to be presented to the occupant from the vehicle, the process proceeds to step S14, and the presentation information determination unit 510 determines information to be presented to the occupant. On the other hand, if there is no information to be presented from the vehicle to the occupant, the process waits in step S12.

  In the next step S <b> 16, the person to be presented identifying unit 520 identifies the person to be presented with information, and the personal authentication unit 532 performs personal authentication of the speaker. The personal authentication unit 532 performs personal authentication for the information presenter identified by the presentee identifying unit 520.

  The personal authentication is performed by a technique such as fingerprint authentication, iris authentication, face authentication, for example. These authentication methods can use a well-known method suitably. For example, the method described in Japanese Patent No. 2722281 for fingerprint authentication, the method described in Japanese Patent No. 3852617 for iris authentication, and Japanese Patent Laid-Open No. 2002-183734 for face authentication. Techniques can be used as appropriate.

  More preferably, the personal authentication is performed when an occupant gets into the vehicle. At this time, in step S16, the result of personal authentication already performed at the time of boarding is applied to the information presenter identified by the presentee identifying unit 520.

  In the next step S <b> 18, the vehicle information acquisition unit 566 acquires vehicle information from the CAN 400. Here, the vehicle information includes information such as vehicle speed, map information, congestion around the vehicle, field of view around the vehicle, steering angle of the steering wheel, weather, navigation device, and the like. The vehicle speed is obtained from a vehicle speed sensor. The congestion situation around the vehicle and the field of view around the vehicle can be acquired from a captured image obtained by the camera 200 imaging the surroundings of the vehicle. The steering angle is obtained from a steering angle sensor. The weather is obtained from information on the weather obtained by the vehicle communicating with the external server 600 or the like. The vehicle information is information related to driving of the vehicle in general, and is not limited to such information.

  In the next step S20, the exception processing unit 530 performs processing in response to the result of personal authentication in step S14. As described above, in the present embodiment, information is presented according to the age of the information presenter. However, for example, when the owner of the vehicle is an information presenter, it is not necessary to perform age estimation processing for a person who is permitted to present information unconditionally regardless of age. The exception processing unit 530 performs exception processing based on the result of personal authentication and permits information presentation to a specific person whose information presentation is permitted unconditionally. Thereby, the process of the system 1000 can be simplified.

  In step S20, the age determination exception determination unit 534 determines whether or not a speaker is registered in the age determination exception database 536 acquired in step S10. In the age determination exception database 536, information such as names and ages of persons to whom exception processing is applied and personal authentication information such as fingerprints, irises, and faces used for personal authentication are stored in association with each other.

  The age determination exception determination unit 534, based on the result of personal authentication, if the personal authentication information such as the fingerprint, iris, face, etc. of the information presenter matches the personal authentication information registered in the age determination exception database 536, It is determined that the information presenter is a person registered in the age determination exception database 536. In this case, since information on the information presenter is registered in the age determination exception database 536, exception processing is applied to the information presenter, and the age estimation unit 540 does not estimate the speaker's age. Therefore, after step S20, the process proceeds to step S28. Further, based on the age of the speaker registered in the age determination exception database 536, the process can proceed to step S30 and subsequent steps.

  On the other hand, if personal authentication fails in step S20, or if the information presenter is not registered in the age determination exception database 536, the process proceeds to step S22 in order to perform normal processing without applying exception processing. In step S22, the vehicle margin calculation unit 564 calculates the vehicle margin based on the vehicle information acquired by the vehicle information acquisition unit 566. The vehicle margin is a parameter representing the margin of the vehicle when the vehicle is being driven, and is set to a value of 0 to 1.0, for example. As an example, the vehicle margin is 0.5 when the vehicle speed is 60 km / h or higher, 0.3 when the vehicle speed is 80 km / h or higher, and 0.3 when the vehicle speed is 100 km / h or higher, depending on the vehicle speed. In this case, 0 is set.

  Further, the vehicle margin is 0.5 when there are other vehicles within 5 m around the vehicle, 0.3 when there are other vehicles within 3 m around the vehicle, depending on the congestion situation around the vehicle, If there is another vehicle within 1.5 m around the vehicle, it is set to 0.

  The vehicle margin is set to 0.3 before the curve, or 0.1 when the vehicle is traveling on a narrow alley, according to the field of view (line of sight) around the vehicle. Further, the vehicle margin is set according to the steering angle of the steering wheel, such as 0.7 when the steering angle is 10 ° or more, and 0 when the steering angle is 90 ° or more. Further, the vehicle margin is set according to the weather, such as 0.8 when the weather is light, 0.1 when the rain is heavy, and 0 when it is snowstorm.

  The vehicle margin can be calculated by multiplying the vehicle speed, the congestion situation, the field of view, the steering angle, and the weather according to the above-described values. The smaller the vehicle margin value is, the less the vehicle driving state is, and there may be a problem in driving when a disturbance occurs.

  After step S22, the process proceeds to step S24. In step S24, the age estimation unit 540 estimates the age of the information presenter. The age estimating unit 540 estimates the age of the information presenter based on the feature amount of the face of the information presenter, the feature amount of the voice, the feature amount of respiration, the result of behavioral analysis or preference analysis, and the like. For example, the method described in Japanese Patent No. 5827225 can be applied to the annual estimation based on the facial feature amount. In addition, for example, a method described in Japanese Patent No. 5637583 can be applied to age estimation based on the feature amount of respiration.

  After step S24, the process proceeds to step S26. In step S26, it is determined whether the age of the information presenter is equal to or greater than a specified age. When the information presenter is older than the specified age, the information presenter is sufficiently mature, and there is no need to restrict the presentation of information. Accordingly, if the age of the information presenter is equal to or greater than the specified age, the process proceeds to step S28, and information is presented without limiting the information to be presented. The specified age in step S26 is set by the age restriction setting unit 552. For example, when the specified age is set to 50 years old, if the speaker is 50 years old or older, the operation is not restricted by age.

  On the other hand, if the age of the information presenter is less than the specified age in step S26, the process proceeds to step S30. In step S30, based on the age estimation result in step S24, the age category determination unit 550 refers to the age category database 554 to determine an age category. FIG. 3 is a schematic diagram illustrating an example of the age category database 554. The age category determination unit 550 refers to the age category database 554 shown in FIG. 3 and sets the age category to “9” when, for example, the age estimation result is 30 to 39 years old.

  After step S30, the process proceeds to step S32. In step S32, the presentation permission determination unit 560 determines whether information can be presented to the information presenter. If the information can be presented, the process proceeds to step S34.

  In step S34, the presentation information changing unit 570 changes the information to be presented. The presentation information changing unit 570 changes the information intensity, information amount, expression content, and the like of the information to be presented based on the information change amount determined by the information change amount determination unit 572. After step S34, the process proceeds to step S28, where the information presenting unit 580 performs a process of presenting information to the information presenter. As a result, information is displayed on the display 300.

  The information change amount determination unit 572 refers to the cognitive physiological characteristic database 574 to determine information intensity, information amount, and expression content. The cognitive physiological characteristics database 574 includes, as cognitive physiological characteristics, visual characteristics for each age (average visual acuity, focal length, etc.), auditory characteristics for each age (high sensitivity frequency, required volume, etc.), information processing characteristics for each age (information) (Processable amount, information processing speed) are stored. The information change amount determination unit 572 refers to the cognitive physiological characteristic database 574. For example, when the information presenter is in his twenties, the information change amount is set to 50 dB or more and the information amount is set to 20 syllables or less. When the person's age is 80's, the volume is 70 dB or more and the amount of information is 10 syllables or less. In this way, as the age increases, the visual characteristics, auditory characteristics, and information processing ability decrease, so the volume of information to be presented, the number of syllables, the size of characters, etc. according to the decrease in visual characteristics and auditory characteristics. By changing it, it is possible to present optimal information according to age.

  Further, the information change amount determination unit 572 changes the expression content of the information according to the age of the information presenter. For example, for young information presenters or elderly information presenters, the expression content is changed to a simple one so that information can be easily transmitted to the information presenters. The content of the expression is determined with reference to the simple expression stored in the simple expression database 573. In the simple expression database 573, the age of the information presenter and the simple expression are stored in association with each other.

  The information change amount determination unit 572 determines information intensity, information amount, and expression content according to the information comprehension level of the information presenter. For this reason, the information comprehension calculation unit 576 calculates the information comprehension level of the information presenter based on the information acquired by the reaction acquisition unit 579. Specifically, the reaction acquisition unit 579 is based on information obtained from the microphone 100, the camera 200, and the like, based on gestures (nods, hand movements, etc.), eye movements, utterance contents, and the like. To get. Then, the information understanding level calculation unit 576 calculates the information understanding level of the information presenter according to the reaction of the information provider. For example, the information comprehension calculation unit 576 determines that the comprehension is high when the information presenter nods based on the reaction of the information presenter acquired by the reaction acquisition unit 579. On the other hand, the information comprehension calculation unit 576 determines that the comprehension is low when the information presenter performs an action of raising his / her head based on the reaction of the information presenter acquired by the reaction acquisition unit 579.

  Furthermore, the information change amount determination unit 572 determines information intensity, information amount, and expression content according to the sex of the information presenter. Therefore, the gender of the information presenter is estimated by the gender estimation unit 578. The information change amount determination unit 572 changes the information intensity, the information amount, and the expression content according to whether the information presenter is male or female. The gender determination by the gender estimation unit 578 is performed by determining the feature amount of the face image captured by the camera 200, the voice feature amount acquired by the microphone 100, the occupant muscle mass estimated from the captured image captured by the camera 200, the occupant behavior or This is performed based on the result of preference analysis.

  If the information cannot be presented in step S32, the process proceeds to step S36. In step S36, the information presenter is notified that the corresponding information cannot be presented. After step S36, the process ends.

  When the presentation permission determination unit 560 determines whether or not information can be presented, the determination is performed with reference to the presentation permission / non-permission database 562 based on the age of the information presenter and the vehicle margin. .

  FIG. 4 is a schematic diagram showing the contents of the presentation permission / non-permission database 562. As shown in FIG. 4, in the presentation permission / non-permission database 562, permission or non-permission of information presentation is defined according to the age of the information presenter and the vehicle margin. In FIG. 4, “collision detection information” indicating the possibility of collision with other traveling vehicles, “restaurant information” indicating surrounding restaurants, “entertainment information”, and “alcohol information” indicating surrounding liquor stores. The case where four of these are presented is shown.

  For example, when the vehicle margin is 1, if the information presenter is 18 to 19 years old, the presentation of liquor store information is not permitted (×), and other information is permitted (◯). The In addition, when the vehicle margin is 1, if the information presenter is 66 years old or older, whose information processing ability is greatly reduced, information processing resources are allocated to entertainment information that does not contribute to driving safety. In order to avoid this, the presentation of entertainment information is not permitted (x), and other information is permitted (o).

  Further, when the vehicle margin is 0.1, more information is refused to be presented. Presentation of collision prediction information is permitted at all ages, but presentation of other information is not permitted. Thereby, when there is no allowance for driving the vehicle, it is possible to facilitate driving the vehicle by reducing the amount of information presented. In FIG. 4, the permission or non-permission of information presentation is prescribed according to both the age of the information presenter and the vehicle margin, but the age of the information presenter and the vehicle margin Permit or non-permission of information presentation may be defined based only on one side.

  As described above, according to the present embodiment, the age of the information presenter and the vehicle margin are determined by determining permission or non-permission of information presentation based on the age of the information presenter and the vehicle margin. It is possible to present optimal information according to the situation.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.
