DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] According to an aspect of the present disclosure, there is provided an information presentation system including a detection unit and a processing unit. The detection unit detects the occurrence of a negative emotion in a vehicle occupant. When the detection unit detects the occurrence of the negative emotion in the occupant, the processing unit executes a process of presenting to the occupant a message that promotes reevaluation of cognitive changes in response to the negative emotion.

[0011] This has the advantage that by presenting a message to the occupant, it becomes easier for the occupant to reconsider negative emotions from a different perspective, making it easier to suppress negative emotions felt by the vehicle occupants.

[0012] In an information presentation system according to another aspect of the present disclosure, the message includes at least one of a message promoting positive reappraisal, a message promoting refocusing on a plan, a message promoting a global perspective, and a message promoting positive refocusing, which are types of subcategorizations of the reappraisal.

[0013] This has the advantage that by presenting a message to the occupants, it becomes easier for them to re-examine their negative emotions from a different perspective, making it easier to suppress the negative emotions felt by the vehicle occupants, particularly the anxiety they may feel.

[0014] In an information presentation system according to another aspect of the present disclosure, the detection unit acquires biometric information of the occupant and detects the occurrence of a negative emotion in the occupant based on the acquired biometric information.

[0015] This has the advantage that the occurrence of a negative emotion in an occupant is detected based on biometric information that may vary depending on the emotion felt by the occupant, making it easier to detect the occurrence of a negative emotion in an occupant with high accuracy.

[0016] In an information presentation system according to another aspect of the present disclosure, the detection unit acquires situational information regarding the situation in which the vehicle is placed, and further detects the possibility of the occupant experiencing a negative emotion and the cause of the occurrence of the negative emotion based on the acquired situational information.

[0017] This has the advantage that it is possible to detect the occurrence of negative emotions in an occupant with higher reliability than detection based on the occupant's biological information.

[0018] In an information presentation system according to another aspect of the present disclosure, when the detection unit detects the occurrence of a negative emotion in the occupant, the detection unit further performs a process of confirming with the occupant whether or not the occupant is harboring the negative emotion.

[0019] This makes it possible to confirm whether the occupant is actually feeling negative emotions, allowing information to be presented to the occupant and, for example, by feeding back the confirmation results, which can be used to improve the accuracy of detecting the occurrence of negative emotions in the occupant.

[0020] In an information presentation system according to another aspect of the present disclosure, when the detection unit detects the possibility of the occupant experiencing a negative emotion, the detection unit further performs a process of confirming with the occupant whether or not the occupant is experiencing the negative emotion.

[0021] This makes it possible to confirm whether the occupant is actually feeling negative emotions, allowing information to be presented to the occupant and, for example, by feeding back the confirmation results, which can be used to improve the accuracy of detecting the occurrence of negative emotions in the occupant.

[0022] In an information presentation system according to another aspect of the present disclosure, in an information presentation system according to another aspect of the present disclosure, the processing unit executes a process of presenting the message to the occupant when the detection unit detects the occurrence of a negative emotion by the occupant while the vehicle is traveling.

[0023] This has the advantage that the influence on the driving of the vehicle caused by the occupants' negative emotions while the vehicle is traveling can be reduced, making it easier to assist the driving of the vehicle.

[0024] In an information presentation system according to another aspect of the present disclosure, when the negative emotion is either anger or irritation, the processing unit performs a process to promote calming of the occupant's negative emotion, and then performs a process to present the message to the occupant.

[0025] This has the advantage that the message is presented to the occupant after attempting to calm negative emotions, for which the effect of reevaluation in cognitive change tends to be relatively small, making it easier to increase the effectiveness of presenting the message in suppressing the negative emotions felt by the occupant.

[0026] In the information presentation system according to another aspect of the present disclosure, the processing unit identifies a cause of the negative emotion based on at least one of a result of self-monitoring of the occupant and situation information related to a situation of the vehicle. The processing unit determines the message to be presented to the occupant based on the identified cause.

[0027] This has the advantage that an appropriate message can be determined depending on the cause of the negative emotion, making it easier to increase the effect of suppressing the negative emotions felt by the occupants by presenting the message.

[0028] In an information presentation system according to another aspect of the present disclosure, the processing unit further performs processing to promote distraction for the occupant.

[0029] This has the advantage that it becomes easier to divert the occupant's attention from the cause of the negative emotion, thereby making it easier to increase the effectiveness of the message in suppressing the negative emotion felt by the occupant.

[0030] In the information presentation system according to another aspect of the present disclosure, the processing unit calculates characteristic information indicating characteristics related to the occurrence of the negative emotion of the occupant based on history data that accumulates data related to the occurrence of the negative emotion of the occupant detected by the detection unit while the vehicle is traveling. When driving of the vehicle is terminated, the processing unit executes a process of presenting the message determined based on the calculated characteristic information to the occupant.

[0031] This has the advantage that when driving the vehicle is finished, a message tailored to the occupant's characteristics is presented to the occupant, which is expected to improve the occupant's psychological skills in suppressing the occurrence of negative emotions.

[0032] In the information presentation system according to another aspect of the present disclosure, the processing unit calculates past characteristic information based on a history of the calculated characteristic information. When the processing unit calculates the characteristic information, the processing unit determines the message to be presented to the occupant based on the calculated characteristic information and the past characteristic information.

[0033] This has the advantage that the message is determined based more on the occupant's past characteristics, which is expected to improve the occupant's psychological skills to suppress the occurrence of negative emotions.

[0034] In an information presentation system according to another aspect of the present disclosure, the processing unit acquires future situation information regarding a future situation that the vehicle will be in. When the processing unit detects, based on the acquired future situation information and the acquired past characteristic information, that the occupant may experience the negative emotion, the processing unit executes a process of presenting the message to the occupant.

[0035] This has the advantage that the message is presented to the occupant before he or she begins to feel negative emotions, making it easier to prevent the occupant from feeling negative emotions in advance.

[0036] In an information presentation method according to one aspect of the present disclosure, the occurrence of a negative emotion in a vehicle occupant is detected, and when the occurrence of the negative emotion in the occupant is detected, a process is executed to present a message to the occupant that encourages reevaluation of cognitive changes in response to the negative emotion.

[0037] This has the advantage that by presenting a message to the occupant, it becomes easier for the occupant to reconsider negative emotions from a different perspective, making it easier to suppress negative emotions felt by the vehicle occupants.

[0038] A program according to an embodiment of the present disclosure causes one or more processors to execute the information presentation method.

[0039] This has the advantage that by presenting a message to the occupant, it becomes easier for the occupant to reconsider negative emotions from a different perspective, making it easier to suppress negative emotions felt by the vehicle occupants.

[0040] Hereinafter, the first to third embodiments will be specifically described with reference to the drawings.

[0041] In addition, the following embodiments 1 to 3 are all comprehensive or specific examples. The numerical values, shapes, materials, components, installation positions and connection forms of the components, steps, order of steps, and the like shown in the following embodiments 1 to 3 are merely examples and are not intended to limit the present disclosure. In addition, among the components in the following embodiments 1 to 3, components that are not described in the independent claims are described as optional components.

[0042] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In addition, in each drawing, the same components are denoted by the same reference numerals.

[0043] (Embodiment 1) <Configuration> FIG. 1 is a block diagram showing an overview of an information presentation system 100 according to a first embodiment. The information presentation system 100 is used in a moving body such as a vehicle, and is a system for assisting driving of the vehicle. In the first embodiment, the information presentation system 100 is realized by an in-vehicle device, but may be realized by an external device brought in from outside the vehicle. In the first embodiment, the passenger targeted by the information presentation system 100 is a driver seated in the driver's seat of the vehicle, but may be a passenger other than the driver seated in the passenger seat or the back seat.

[0044] 1, the information presentation system 100 includes a detection unit 1, a processing unit 2, a storage unit 3, a microphone 4, and a speaker 5. Note that the storage unit 3, the microphone 4, and the speaker 5 do not necessarily have to be included as components of the information presentation system 100.

[0045] The detection unit 1 is realized by, for example, an ECU (Electronic Control Unit), and detects the occurrence of negative emotions in a vehicle occupant. In the first embodiment, the negative emotions that the detection unit 1 can detect are any of anger, irritation (irritability), and anxiety. The detection unit 1 may detect the occurrence of a plurality of negative emotions. Furthermore, the detection unit 1 may detect not only the type of negative emotion that occurs, but also the intensity of the negative emotion that occurs or the probability of the occurrence of the negative emotion.

[0046] The detection unit 1 has a direct feeling deduction unit 11, an indirect feeling deduction unit 12, and an emotion occurrence confirmation unit 13. In the first embodiment, the detection unit 1 exerts the functions of each of the direct feeling deduction unit 11, the indirect feeling deduction unit 12, and the emotion occurrence confirmation unit 13 by executing a program stored in advance in an internal memory, for example.

[0047] The direct feeling estimation unit 11 directly estimates the occurrence of a negative feeling of the occupant based on information obtained directly from the occupant. Specifically, the direct feeling estimation unit 11 acquires biometric information of the occupant and detects the occurrence of a negative feeling of the occupant based on the acquired biometric information. Here, the biometric information may include, for example, the facial expression of the occupant, the voice uttered by the occupant, or the heart rate of the occupant.

[0048] For example, information indicating the facial expression of the occupant can be obtained by capturing an image of the occupant's face with a camera mounted on the vehicle. The direct emotion estimation unit 11 then executes an appropriate image analysis algorithm on the captured facial image to estimate whether the occupant is experiencing any of the negative emotions of anger, irritation, or anxiety. As an example, if the facial image shows an expression in which the occupant has vertical wrinkles between the eyebrows, the direct emotion estimation unit 11 estimates that the occupant is experiencing the negative emotion of anger or irritation. (Reference: Introduction to Facial Expression Analysis, P. Ekman, WV Friesen, Kudo Chikara (ed. and translator), original work: UNMASKING THE FACE: 1975)

[0049] Also, for example, information indicating the voice uttered by the occupant can be acquired by collecting the voice uttered by the occupant with the microphone 4. Then, the direct emotion estimation unit 11 estimates whether the occupant has any of the negative emotions of anger, irritation, or anxiety by executing an appropriate voice recognition algorithm on the collected voice uttered by the occupant. As an example, if the voice uttered by the occupant includes words such as complaining, the direct emotion estimation unit 11 estimates that the occupant has the negative emotion of anger or irritation. Also, the direct emotion estimation unit 11 may estimate the occurrence of a negative emotion by analyzing a voice signal.

[0050] Also, for example, information indicating the passenger's heart rate can be acquired from a wearable device, such as a smart watch or smart glasses, that is attached to the passenger's wrist, arm, or head and has a function of measuring the heart rate. The direct emotion estimation unit 11 then executes an appropriate analysis algorithm on the acquired information indicating the passenger's heart rate to estimate whether the passenger is experiencing any of the negative emotions of anger, irritation, or anxiety. As an example, if the passenger's heart rate exceeds a preset threshold, the direct emotion estimation unit 11 estimates that the passenger is experiencing the negative emotion of anger. (Reference: Dzedzickis, Human Emotion Recognition: Review of Sensors ana Methods, 2020)

[0051] The direct feeling estimation unit 11 may detect the occurrence of a negative feeling in an occupant based on only one type of biometric information among the above-mentioned three types of biometric information, or may detect the occurrence of a negative feeling in an occupant based on two or more types of biometric information.

[0052] The indirect feeling estimation unit 12 indirectly estimates the possibility of the occupant's negative feeling and the cause of the negative feeling based on information indirectly obtained from the occupant. Specifically, the indirect feeling estimation unit 12 acquires situation information related to the situation in which the vehicle is placed, and detects the possibility of the occupant's negative feeling and the cause of the negative feeling based on the acquired situation information. Here, the situation information may include, for example, the surrounding brightness (daytime, nighttime, etc.), the weather (sunny, cloudy, rainy, etc.), or the traffic conditions (a road traveled for the first time, a destination for the first time, a narrow road, a junction, a traffic jam, etc.). In addition, the situation information may include, for example, surrounding information related to surrounding vehicles. The surrounding information may include, for example, information indicating surrounding vehicles when the vehicle is parked, information indicating surrounding vehicles when the vehicle is changing lanes, or information indicating tailgating by surrounding vehicles (cutting the distance between vehicles or honking the horn, etc.).

[0053] For example, the information indicating the brightness of the surroundings can be acquired from an illuminance sensor mounted on the vehicle. Then, the indirect feeling deduction unit 12 executes an appropriate analysis algorithm on the acquired information indicating the brightness of the surroundings to infer whether or not the situation is likely to cause the occupant to feel any of the negative feelings of anger, irritation, or anxiety. As an example, if the information indicating the brightness of the surroundings indicates nighttime, the indirect feeling deduction unit 12 infers that the occupant may be experiencing the negative feeling of anxiety, and determines that the cause of the occurrence is nighttime.

[0054] Also, for example, the information indicating the weather can be acquired from a server operated by a service provider that provides weather information. Then, the indirect feeling deduction unit 12 executes an appropriate analysis algorithm on the acquired information indicating the weather to infer whether or not the situation is likely to cause the occupant to feel any of the negative feelings of anger, irritation, or anxiety. As an example, if the information indicating the weather indicates rain, the indirect feeling deduction unit 12 infers that the occupant may be experiencing the negative feeling of anxiety, and determines that the cause is rain.

[0055] Also, for example, the information indicating the traffic situation can be acquired from a navigation system mounted on the vehicle or on a mobile terminal such as a smartphone carried by the occupant. Then, the indirect feeling deduction unit 12 executes an appropriate analysis algorithm on the acquired information indicating the traffic situation to estimate whether or not the situation is likely to cause any of the negative feelings of anger, irritation, or anxiety in the occupant. As an example, if the information indicating the traffic situation indicates a traffic jam, the indirect feeling deduction unit 12 estimates that the occupant may be experiencing the negative feeling of irritation, and determines that the cause is the traffic jam.

[0056] Also, for example, the surrounding information can be acquired from a distance sensor, a gyro sensor, or the microphone 4 mounted on the vehicle. Then, the indirect feeling estimation unit 12 executes an appropriate analysis algorithm on the acquired surrounding information to estimate whether or not the situation is likely to cause the occupant to feel any of the negative feelings of anger, irritation, or anxiety. As an example, if the surrounding information indicates surrounding vehicles when the vehicle is changing lanes, the indirect feeling estimation unit 12 estimates that the occupant may be experiencing the negative feeling of anxiety, and determines that the cause is the lane change.

[0057] When the detection unit 1 detects the occurrence of a negative emotion in the occupant or the possibility of the occurrence of a negative emotion, the emotion occurrence confirmation unit 13 executes a process of confirming with the occupant whether or not the occupant is feeling a negative emotion. Specifically, the emotion occurrence confirmation unit 13 outputs a message, for example, "Are you currently feeling anger (or irritation, anxiety)?" as a voice from the speaker 5 to the occupant. Then, the emotion occurrence confirmation unit 13 picks up the voice of the occupant in response to the question with the microphone 4, and recognizes whether the voice is a voice meaning positive or negative by executing an appropriate voice recognition algorithm on the collected voice. If the voice is a voice meaning positive, the emotion occurrence confirmation unit 13 determines that the occupant has experienced a negative emotion. On the other hand, if the voice is a voice meaning negative, the emotion occurrence confirmation unit 13 determines that the occupant has not experienced a negative emotion. The process of confirming with the occupant whether or not the occupant is feeling a negative emotion may be executed by having the occupant press a confirmation button corresponding to "yes" or "no."

[0058] The processing unit 2 is realized by, for example, an ECU, and executes various processes for assisting the vehicle occupant in driving. In the first embodiment, the processing unit 2 has an identification unit 21, a presentation unit 22, a calming down promotion unit 23, and a distraction promotion unit 24. In the first embodiment, the processing unit 2 exerts the functions of the identification unit 21, the presentation unit 22, the calming down promotion unit 23, and the distraction promotion unit 24 by executing a program stored in advance in, for example, an internal memory.

[0059] The identification unit 21 identifies the cause of the negative emotion based on at least one of the result of the occupant's self-monitoring and the situation information. Here, self-monitoring refers to having the occupant verbally explain the current situation, thoughts, actions, or his / her own emotions. The calming promotion unit 23, which will be described later, may encourage the occupant to perform self-monitoring.

[0060] For example, if the current situation included in the result of self-monitoring indicates that the vehicle is being tailgated by a surrounding vehicle, the identification unit 21 identifies that the cause of the negative emotion is tailgating by the surrounding vehicle. Also, for example, if the situation information indicates a road on which the vehicle is traveling for the first time, the identification unit 21 identifies that the cause of the negative emotion is a road on which the vehicle is traveling for the first time.

[0061] When the detection unit 1 detects the occurrence of a negative emotion in the occupant, the presentation unit 22 executes a process of presenting to the occupant a message that promotes a "cognitive change (reevaluation)" (hereinafter also referred to as "reevaluation in cognitive change") in response to the negative emotion. Here, "cognitive change (reevaluation)" is a method belonging to cognitive change among situation selection, situation modification, attention allocation, cognitive change, and response adjustment, which are known as methods for controlling emotions, and refers to changing the evaluation of the situation or one's own abilities in order to change the emotion evoked by the situation. For the above-mentioned method of controlling emotions, please refer to, for example, "Emotion Regulation Handbook, Chapter 12 et al., 2022" and "JJ Gross, Antecedent- and response-focused emotion regulation: Divergent consequences for experience, expression, and physiology. Journal of Personality and Social Psychology, 1998".

[0062] Situation selection refers to the selection of whether or not to participate in a situation (environment or stimulus) that is predicted to arouse emotions. For example, if a passenger is likely to feel negative emotions such as irritation due to traffic congestion, it is known that the passenger can suppress negative emotions by making a situation selection to avoid the traffic congestion by referring to traffic congestion forecast information in advance.

[0063] Situation modification refers to modifying the situation (environment or stimuli) to change the impact of the emotion being evoked. For example, if a passenger feels a negative emotion of anger after being cut off by a nearby vehicle, it is known that the passenger can suppress the negative emotion by immediately increasing the distance between the vehicle and the surrounding vehicle.

[0064] Attention allocation refers to paying attention to a situation or oneself or turning away attention from a situation or oneself in order to change emotions. For example, if a driver is a novice driver and feels negative emotions such as anxiety, it is known that the driver can suppress negative emotions by allocating attention to listening to music that the driver likes or smelling a scent that the driver likes to distract the driver.

[0065] Response regulation refers to directly regulating an emotional response after an emotion is aroused. For example, if a passenger is a novice driver and feels a negative emotion such as anxiety, it is known that response regulation such as taking a deep breath to calm down can suppress the negative emotion.

[0066] Unlike the above-mentioned situation selection, situation modification, attention allocation, and response adjustment, the presentation unit 22 presents the occupant with a message that promotes "cognitive change (reappraisal)," encouraging the occupant to reconsider negative emotions from a different perspective and suppressing the occupant's negative emotions. Unlike other methods, "cognitive change (reappraisal)" is said to have the effect of improving psychological skills that not only deal with emotions at the time, but also make it difficult to feel negative emotions themselves. Reappraisal is further classified, and of these, four types are said to be effective: positive reappraisal, refocusing on plans, taking a global perspective, and positive refocusing. (Reference: Meta-analysis of the relationship between cognitive emotion control scales and depression and anxiety, 2016)

[0067] In the first embodiment, the message presented by the presentation unit 22 includes at least one of a message promoting positive reevaluation, which is a type of subcategory of "cognitive change (reevaluation)", a message promoting refocusing on a plan, a message promoting a global perspective, and a message promoting positive refocusing. Positive reevaluation refers to thinking positively about the current situation from the perspective of personal growth. Refocusing on a plan refers to thinking about how to deal with the current situation to change it. The global perspective refers to downplaying the seriousness of the current situation or thinking that the current situation is better than other negative situations. Positive refocusing refers to thinking about positive things that are unrelated to the current situation. Specific examples of messages presented by the presentation unit 22 will be described in <Operation> below.

[0068] Here, when the identification unit 21 identifies the cause of the negative emotion, the presentation unit 22 determines a message to be presented to the occupant based on the identified cause. Specifically, the presentation unit 22 selects a candidate linked to the cause of the negative emotion from among multiple message candidates to determine the message. For example, if the cause of the negative emotion is traffic congestion, the presentation unit 22 selects a candidate that mentions traffic congestion from among multiple message candidates to determine the message.

[0069] In the first embodiment, the presentation unit 22 reads out a message to be presented from a plurality of message candidates stored in the storage unit 3, and presents the message to the occupant by outputting the read out message as a voice from the speaker 5. The voice may be a mechanical voice, or may be a recorded voice uttered by a person.

[0070] The presentation unit 22 may generate a message to be presented using a message generation model that has been machine-learned in advance to output a message that promotes "cognitive change (reevaluation)" using, for example, negative emotions and the causes of the negative emotions as inputs. In this case, it is not necessary to store multiple message candidates in the storage unit 3.

[0071] The calming promotion unit 23 executes a process for promoting calming of the occupant's negative emotion (hereinafter also referred to as "calming promotion process") when the occupant's negative emotion detected by the detection unit 1 is either anger or irritation. Specifically, the calming promotion unit 23 outputs, as a voice from the speaker 5, a message encouraging the occupant to take a deep breath or to engage in self-talk. Here, self-talk refers to talking to oneself or uttering self-suggestive words to calm oneself. In addition, the calming promotion unit 23 outputs, as a voice from the speaker 5, a message encouraging the occupant to engage in self-monitoring, for example.

[0072] Furthermore, for example, calming down promotion unit 23 may control speaker 5 to play music, or may control an aroma diffuser mounted in the vehicle to emit a fragrance. Furthermore, for example, calming down promotion unit 23 may control a lighting device mounted in the vehicle to change the lighting environment, or may control an air conditioner mounted in the vehicle to change the temperature inside the vehicle.

[0073] The distraction promotion unit 24 further executes a process for promoting the distraction of the occupant (hereinafter, also referred to as a "distraction promotion process") when the presentation unit 22 presents a message to the occupant. Specifically, the distraction promotion unit 24 plays music that matches the occupant's preferences from the speaker 5, or generates a scent that matches the occupant's preferences from an aroma diffuser mounted in the vehicle. Note that information indicating the music that matches the occupant's preferences or information indicating the scent that matches the occupant's preferences is stored in advance in the storage unit 3, for example.

[0074] Before executing the distraction promotion process, the distraction promotion unit 24 may output a message as a voice from the speaker 5, asking the occupant whether or not the process is acceptable. In this case, if the distraction promotion unit 24 receives a positive response from the occupant, the distraction promotion unit 24 executes the process. On the other hand, if the distraction promotion unit 24 receives a negative response from the occupant, the distraction promotion unit 24 does not execute the process.

[0075] The storage unit 3 is, for example, a semiconductor memory, and is a dedicated or general-purpose memory for storing information used in the information presentation system 100. The storage unit 3 stores, for example, a plurality of message candidates that can be presented to the occupant by the presentation unit 22.

[0076] <Operation> Hereinafter, the operation of the information presentation system 100 according to the first embodiment will be described with reference to Fig. 2. Fig. 2 is a flowchart showing an example of the operation of the information presentation system 100 according to the first embodiment. The operation described below is executed while the vehicle is traveling (including when the vehicle is temporarily stopped).

[0077] First, the direct feeling estimation unit 11 of the detection unit 1 directly estimates the occurrence of a negative feeling (S101). Also, the indirect feeling estimation unit 12 of the detection unit 1 indirectly estimates the occurrence of a negative feeling (S102). Note that steps S101 and S102 may be executed in a different order than the above order, or may be executed in parallel.

[0078] While neither the direct feeling estimation unit 11 nor the indirect feeling estimation unit 12 estimates the occurrence of a negative emotion or the possibility of the occurrence of a negative emotion, that is, while the occurrence of a negative emotion is not detected (S103: No), steps S101 and S102 are repeated. On the other hand, when the direct feeling estimation unit 11 estimates the occurrence of a negative emotion and the indirect feeling estimation unit 12 also estimates the possibility of the occurrence of a negative emotion of the occupant, that is, when the occurrence of a negative emotion is detected (S103: Yes), the emotion occurrence confirmation unit 13 executes a process of confirming the occurrence of a negative emotion with the occupant (S104). Note that the information presentation system 100 does not need to include the indirect feeling estimation unit 12. In that case, if the occurrence of an emotion is estimated by the direct feeling estimation unit 11, the emotion occurrence confirmation unit 13 executes the process.

[0079] Then, the presentation unit 22 of the processing unit 2 executes a process of presenting to the occupant a message that promotes "cognitive change (reevaluation)" according to the negative emotion (S105). Note that, if a response denying the occurrence of a negative emotion is obtained from the occupant in step S104, the process may return to steps S101 and S102 without executing step S105.

[0080] Fig. 3 is a flowchart showing a specific example of a process of presenting a message to an occupant in the information presentation system 100 according to the embodiment 1. Fig. 3(a) shows an example in which the detection unit 1 detects the occurrence of a negative emotion indicating anger or irritation in the occupant, and Fig. 3(b) shows an example in which the detection unit 1 detects the occurrence of a negative emotion indicating anxiety in the occupant.

[0081] 3(a), when the detection unit 1 detects the occurrence of a negative emotion indicating anger or irritation of an occupant, the calming promotion unit 23 of the processing unit 2 first executes a calming promotion process (S201). Next, the identification unit 21 of the processing unit 2 identifies the cause of the occurrence of the negative emotion (S202). Note that steps S201 and S202 may be executed in a different order than the above, or may be executed in parallel.

[0082] Next, the processing unit 2 determines a message (e.g., a message related to a global perspective) that promotes a "cognitive change (reassessment)" based on the cause identified by the identification unit 21 (S203). Then, the presentation unit 22 of the processing unit 2 executes a process of presenting the message determined in step S203 to the occupant (S204). In addition, the distraction promotion unit 24 of the processing unit 2 executes a distraction promotion process (S205). Step S205 may be executed after execution of step S204, or may be executed simultaneously with step S204.

[0083] 3(b), when the detection unit 1 detects the occurrence of a negative emotion indicating anxiety of an occupant, the identification unit 21 of the processing unit 2 first identifies the cause of the occurrence of the negative emotion (S301). Next, the processing unit 2 determines a message (e.g., a message regarding refocusing on a plan, or a message regarding a global perspective, etc.) that promotes a "cognitive change (reevaluation)" based on the cause identified by the identification unit 21 (S302).

[0084] The message may include information or advice for relieving the anxiety of the occupant. This encourages the occupant to refocus on the plan and is expected to reduce anxiety by improving the occupant's self-efficacy. Here, self-efficacy refers to the recognition of one's own potential, such as the expectation or confidence that one can appropriately deal with the current situation.

[0085] Then, the presentation unit 22 of the processing unit 2 executes a process of presenting the message determined in step S302 to the occupant (S303). Also, the distraction promotion unit 24 of the processing unit 2 executes a distraction promotion process (S304). Step S304 may be executed after execution of step S303, or may be executed simultaneously with step S303.

[0086] 4 is a diagram showing an example of a message to be presented to an occupant in the information presentation system 100 according to the first embodiment. The presentation unit 22 determines a message to be presented to an occupant according to the negative emotion of the occupant detected by the detection unit 1. For example, when the detection unit 1 detects the occurrence of a negative emotion indicating anger in the occupant, the presentation unit 22 determines a message in the row of "anger" shown in FIG. 4 and in any of the four columns of "cognitive change (reappraisal)", namely, "positive reappraisal", "refocus on plan", "big picture perspective", and "positive refocus".

[0087] 4, the message in the "attention allocation" column is an example of a message presented to the occupant before the distraction promotion unit 24 executes the distraction promotion process. Also, in FIG. 4, the message in the "empathy" column is an example of a message showing empathy with the occupant's negative emotion. For example, when presenting a message promoting "cognitive change (reevaluation)", the presentation unit 22 may also present a message in the "empathy" column in accordance with the occupant's negative emotion detected by the detection unit 1.

[0088] <Advantages> Advantages of the information presentation system 100 according to the first embodiment will be described below. As described above, when the information presentation system 100 according to the first embodiment detects the occurrence of a negative emotion in a vehicle occupant, the information presentation system 100 executes a process of presenting to the occupant a message that promotes a "cognitive change (reassessment)" in response to the negative emotion. Therefore, the information presentation system 100 according to the first embodiment has an advantage that by presenting a message to the occupant, the occupant can easily reinterpret the negative emotion from a different perspective, and therefore the negative emotion felt by the vehicle occupant can be easily suppressed.

[0089] Here, it is known that an effective method is to issue a warning to occupants when they fall asleep or are distracted while driving. However, when a negative emotion occurs in an occupant, issuing a warning or a message to call attention to the occupant may not suppress the negative emotion and may have the opposite effect. In contrast, the information presentation system 100 according to the first embodiment presents the occupant with a message that promotes "cognitive change (reevaluation)," which is considered to be particularly effective in suppressing negative emotions, and therefore has the advantage of making it easier to suppress the negative emotions felt by the occupant.

[0090] (Embodiment 2) <Configuration> 5 is a block diagram showing an overview of an information presentation system 100A according to embodiment 2. The information presentation system 100A according to embodiment 2 differs from the information presentation system 100 according to embodiment 1 in that the processing unit 2 further includes a characteristic information calculation unit 25. The information presentation system 100A according to embodiment 2 also differs from the information presentation system 100 according to embodiment 1 in that the storage unit 3 includes a history database (hereinafter, referred to as "history DB") 31. Hereinafter, explanations of points common to embodiment 1 will be omitted as appropriate.

[0091] The characteristic information calculation unit 25 calculates characteristic information indicating characteristics related to the occurrence of negative emotions of the occupant based on history data that is accumulated data related to the occurrence of negative emotions of the occupant detected by the detection unit 1 while the vehicle is traveling. The history data is stored in the history DB 31 of the storage unit 3.

[0092] Here, the data regarding the occurrence of the negative emotion of the occupant may include, for example, the time when the negative emotion occurred, the duration of the negative emotion, the situation in which the occupant was placed when the negative emotion occurred, etc. The situation in which the occupant was placed may include, for example, whether or not the road is a first time for the occupant, whether or not the destination is a first time for the occupant, the speed of the vehicle, the distance between the vehicle and other vehicles, the time of day, the weather, or the traffic conditions, etc.

[0093] The characteristic information calculation unit 25 calculates the characteristic information by executing an appropriate analysis algorithm on the history data. Here, the characteristic information may include, for example, the frequency of occurrence of negative emotions for a certain travel distance or travel time, the cumulative time of occurrence of negative emotions, the cumulative intensity of negative emotions, or the tendency of the vehicle's condition when negative emotions occur (rainy weather, traffic jam, etc.). In addition, the characteristic information may include a correlation between whether or not the road is a first-time road for the occupant and the negative emotions, or a correlation between whether or not the destination is a first-time destination for the occupant and the negative emotions, etc.

[0094] <Operation> Hereinafter, the operation of the information presentation system 100A according to the second embodiment will be described with reference to Fig. 6. Fig. 6 is a flowchart showing an example of the operation of the information presentation system 100A according to the second embodiment. Note that while the vehicle is traveling, the information presentation system 100A according to the second embodiment executes the same operation as the information presentation system 100 according to the first embodiment, but the description thereof will be omitted here.

[0095] First, when the vehicle is traveling (S401: No), the processing unit 2 accumulates data on the occurrence of the negative emotion of the occupant detected by the detection unit 1 in the history DB 31 (S402). After that, when the vehicle stops traveling (S401: Yes), the characteristic information calculation unit 25 of the processing unit 2 calculates characteristic information based on the history data stored in the history DB 31 (S403) and stores the calculated characteristic information in the storage unit 3 (S404). Note that steps S403 and S404 may be executed while the vehicle is traveling.

[0096] Next, the processing unit 2 determines a message (e.g., a message regarding positive reevaluation or a message regarding a global perspective) that promotes "cognitive change (reevaluation)" based on the calculated characteristic information (S405). Then, the presentation unit 22 of the processing unit 2 executes a process of presenting the message determined in step S405 to the occupant (S406).

[0097] Fig. 7 is a diagram showing an example of a message to be presented to an occupant in the information presentation system 100A according to the second embodiment. The presentation unit 22 determines a message to be presented to the occupant according to the characteristic information. For example, when the characteristic information indicates that the occupant is prone to negative feelings of anxiety, the presentation unit 22 determines a message in the row of "anxiety tendency" shown in Fig. 7 and in any of the four columns of "cognitive change (reevaluation)", namely "positive reevaluation", "refocus on plan", "big perspective", and "positive refocus".

[0098] 7, the message in the "Empathy" column is an example of a message showing empathy with the occupant's negative emotion. For example, when presenting a message promoting "cognitive change (reevaluation)", the presentation unit 22 may further present a message in the "Empathy" column in accordance with the characteristic information.

[0099] <Advantages> The advantages of the information presentation system 100A according to the second embodiment will be described below. As described above, the information presentation system 100A according to the second embodiment calculates characteristic information based on history data accumulated while the vehicle is traveling. Then, when the vehicle stops traveling (i.e., when driving of the vehicle is finished), the information presentation system 100A according to the second embodiment executes a process of presenting a message determined based on the calculated characteristic information to the occupant.

[0100] Therefore, the information presentation system 100A according to the second embodiment has an advantage that a message according to the characteristics of the occupant is presented to the occupant when the driving of the vehicle is finished, and therefore it is expected that the occupant's psychological skill for suppressing the occurrence of negative emotions can be improved. For example, if the occupant tends to have negative emotions such as anxiety while driving the vehicle, by receiving the above message when the driving of the vehicle is finished, it is expected that the occupant will be less likely to have negative emotions such as anxiety the next time he or she drives the vehicle.

[0101] Here, in the second embodiment, the characteristic information calculation unit 25 of the processing unit 2 may calculate past characteristic information based on a history of calculated characteristic information. Then, when the characteristic information is calculated, the presentation unit 22 of the processing unit 2 may determine a message to be presented to the occupant based on the characteristic information and the past characteristic information.

[0102] For example, the characteristic information calculation unit 25 calculates, as past characteristic information, an average value of the cumulative time during which a negative emotion (e.g., irritation) occurred for a certain driving distance based on the history of the characteristic information for multiple times in the past (e.g., 10 times) or for a certain period (e.g., one month).Then, the presentation unit 22 may compare the calculated past characteristic information with the currently acquired characteristic information, and if, for example, the cumulative time during which irritation occurred during the current driving is longer than during the past driving, determine a message to that effect and including advice for the next driving.

[0103] The characteristic information history and past characteristic information are stored in the storage unit 3 for each occupant. Specifically, the characteristic information history and past characteristic information are linked to the occupant's identifier and stored in the storage unit 3. When reading out the characteristic information history and past characteristic information from the storage unit 3, the processing unit 2 may refer to the occupant's identifier obtained, for example, by an authentication process executed when the occupant gets into the vehicle.

[0104] (Embodiment 3) <Configuration> 8 is a block diagram showing an overview of an information presentation system 100B according to embodiment 3. The information presentation system 100B according to embodiment 3 differs from the information presentation system 100A according to embodiment 2 in that the processing unit 2 further includes an occurrence possibility detection unit 26. Hereinafter, explanations of points common to embodiment 2 will be omitted as appropriate.

[0105] The occurrence possibility detection unit 26 acquires future situation information regarding a future situation in which the vehicle will be placed, and detects the possibility that a negative emotion will occur in the occupant based on the acquired future situation information and past characteristic information. Here, the future situation information may include surrounding brightness, weather, traffic conditions, etc. in the future (e.g., several hours from the present time).

[0106] For example, when the future situation information indicates the occurrence of traffic congestion on a future travel route and the past characteristic information indicates a tendency for the occupant to have negative emotions when traffic congestion occurs, the occurrence possibility detection unit 26 detects that the occupant may have negative emotions. Also, for example, when the future situation information indicates travel at night and the past characteristic information indicates a tendency for the occupant to have negative emotions when travelling at night, the occurrence possibility detection unit 26 detects that the occupant may have negative emotions.

[0107] Also, for example, when the future situation information indicates that it will rain during driving and the past characteristic information indicates that the occupant tends to have negative emotions when driving in the rain, the occurrence possibility detection unit 26 detects that the occupant may have negative emotions. Also, for example, when the future situation information indicates that the road on which the vehicle is to be driven is a road that the vehicle has never driven on before or a destination that the vehicle has never reached before and the past characteristic information indicates that the occupant tends to have negative emotions toward a road that the vehicle has never driven on before or a destination that the vehicle has never reached before, the occurrence possibility detection unit 26 detects that the occupant may have negative emotions.

[0108] <Operation> Hereinafter, the operation of the information presentation system 100B according to the third embodiment will be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of the operation of the information presentation system 100B according to the third embodiment. The information presentation system 100B according to the third embodiment performs the same operation as the information presentation system 100 according to the first embodiment while the vehicle is traveling, and performs the same operation as the information presentation system 100A according to the second embodiment at the end of the vehicle's traveling, but the description thereof will be omitted here. The operations described below are performed before the vehicle starts traveling or while the vehicle is traveling.

[0109] First, the occurrence possibility detection unit 26 of the processing unit 2 acquires future situation information (S501). In addition, the occurrence possibility detection unit 26 of the processing unit 2 acquires past characteristic information by reading the past characteristic information from the storage unit 3 (S502). Note that steps S501 and S502 may be executed in a different order than the above, or may be executed in parallel.

[0110] Next, when the occurrence possibility detection unit 26 of the processing unit 2 detects that the occupant may experience a negative emotion based on the future situation information and the past characteristic information (S503: Yes), the presentation unit 22 of the processing unit 2 executes a process of presenting the occupant with a message promoting "cognitive change (reevaluation)" (S504). On the other hand, when the occurrence possibility detection unit 26 does not detect that the occupant may experience a negative emotion (S503: No), the presentation unit 22 does not present the message to the occupant.

[0111] Fig. 10 is a diagram showing an example of a message to be presented to an occupant in the information presentation system 100B according to the third embodiment. The presentation unit 22 determines a message to be presented to an occupant according to past characteristic information. For example, when the past characteristic information indicates that the occupant is prone to negative feelings of anxiety, the presentation unit 22 determines a message in the row of "anxiety tendency" shown in Fig. 10 and in any of the four columns of "cognitive change (reevaluation)", namely "positive reevaluation", "refocusing on plan", "big perspective", and "positive refocusing".

[0112] 10, the messages in the "attention allocation" column are examples of messages presented to the occupant before the distraction promotion unit 24 executes the distraction promotion process. For example, the distraction promotion unit 24 may present the message in the "attention allocation" column when the presentation unit 22 presents a message to promote "cognitive change (reappraisal)".

[0113] <Advantages> Hereinafter, a description will be given of advantages of the information presentation system 100B according to the embodiment 3. As described above, the information presentation system 100B according to the embodiment 3 acquires future situation information, and when it is detected that the occupant may experience a negative emotion based on the acquired future situation information and past characteristic information, a process of presenting a message to the occupant is executed.

[0114] Therefore, the information presentation system 100B according to the third embodiment presents a message to the occupant before the occupant feels a negative emotion, and thus has an advantage in that it is easy to prevent the occupant from feeling a negative emotion in advance.

[0115] (Modification) Although the information presentation system according to the present disclosure has been described based on the above-mentioned embodiments, the present disclosure is not limited to these embodiments. As long as the modifications do not deviate from the spirit of the present disclosure, modifications that a person skilled in the art may make to the embodiments may also be included within the scope of the present disclosure.

[0116] In each of the above-described embodiments, the presentation unit 22 of the processing unit 2 presents a message to the occupant by outputting the message as sound from the speaker 5, but is not limited to this. For example, the presentation unit 22 may present the message to the occupant by displaying the message on a head-up display (HUD) mounted on the vehicle. The presentation unit 22 may also present the message to the occupant by both outputting the message as sound from the speaker 5 and displaying it on the HUD.

[0117] In each of the above embodiments, the presentation unit 22 of the processing unit 2 may change the type of voice to be output from the speaker 5 depending on the occupant. For example, the presentation unit 22 may present a message to the occupant by outputting from the speaker 5 a male voice, a female voice, a child's voice, the voice of an actor that the occupant likes, or the voice of a character that the occupant likes, depending on the occupant. Also, for example, the presentation unit 22 may present a message to the occupant by outputting from the speaker 5 a voice in a dialect such as Kansai dialect depending on the occupant.

[0118] In each of the above embodiments, the detection unit 1 may detect the occurrence of a negative emotion in the occupant based on the occupant's declaration. Specifically, the detection unit 1 may ask the occupant whether or not a negative emotion has occurred through the emotion occurrence confirmation unit 13, and may determine that the occupant has experienced a negative emotion when an affirmative answer is received. In this case, the direct emotion estimation unit 11 and the indirect emotion estimation unit 12 are not necessary.

[0119] In each of the above-described embodiments, the processing unit 2 may not have the calming down promotion unit 23. In other words, the presentation unit 22 of the processing unit 2 may execute a process of presenting a message to the occupant without executing the calming down promotion process.

[0120] In each of the above-described embodiments, the processing unit 2 may not have the distraction promotion unit 24. In other words, the presentation unit 22 of the processing unit 2 may execute a process of presenting a message to the occupant without executing a distraction promotion process.

[0121] In each of the above embodiments, the information presentation systems 100, 100A, and 100B may be realized by an IVI (In-Vehicle Infotainment) system, which is an in-vehicle information and communication system using, for example, a car navigation system, a display, and an audio system.

[0122] In addition, in each of the above-mentioned embodiments, the information presentation system 100, 100A, 100B is realized by an in-vehicle device, but is not limited thereto. For example, the information presentation system 100, 100A, 100B may be mounted on a server device separate from the vehicle, and may present a message to the occupant by performing wireless communication between the server device and the vehicle. In addition, the information presentation system 100, 100A, 100B may be a composite configuration in which a part of the information presentation system is mounted on the vehicle and the rest is mounted on the server device.

[0123] Each unit included in the information presentation systems 100, 100A, and 100B according to the above-described embodiments is typically realized as an LSI (Large-Scale Integration) integrated circuit. These units may be individually integrated into one chip, or may be integrated into one chip so as to include some or all of them.

[0124] The integrated circuit is not limited to an LSI, but may be realized by a dedicated circuit or a general-purpose processor. A field programmable gate array (FPGA) that can be programmed after the LSI is manufactured, or a reconfigurable processor that can reconfigure the connections and settings of the circuit cells inside the LSI may also be used.

[0125] In each of the above embodiments, each component may be implemented by dedicated hardware or by executing a software program suitable for each component. Each component may be implemented by a program execution unit such as a CPU (Central Processing Unit) or a processor reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory.

[0126] Furthermore, all the numbers used above are merely examples for specifically explaining the present disclosure, and each embodiment of the present disclosure is not limited to the exemplified numbers.

[0127] In addition, the division of functional blocks in the block diagram is an example, and multiple functional blocks may be realized as one functional block, one functional block may be divided into multiple blocks, or some functions may be transferred to another functional block. Furthermore, the functions of multiple functional blocks having similar functions may be processed in parallel or in a time-sharing manner by a single piece of hardware or software.

[0128] In addition, the order in which each step is performed in the flowchart is merely for illustrative purposes and may be other than the above. In addition, some of the steps may be performed simultaneously (in parallel) with other steps.

[0129] In addition, the present disclosure also includes forms obtained by applying various modifications to each embodiment that a person skilled in the art may conceive, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope that does not deviate from the spirit of the present disclosure.

[0130] (summary) As described above, the information presentation systems 100, 100A, and 100B according to the first embodiment include the detection unit 1 and the processing unit 2. The detection unit 1 detects the occurrence of a negative emotion in a vehicle occupant. When the detection unit 1 detects the occurrence of a negative emotion in the occupant, the processing unit 2 executes a process of presenting to the occupant a message that promotes reevaluation of cognitive changes in response to the negative emotion.

[0131] This has the advantage that by presenting a message to the occupant, it becomes easier for the occupant to reconsider negative emotions from a different perspective, making it easier to suppress negative emotions felt by the vehicle occupants.

[0132] In the information presentation systems 100, 100A, and 100B according to the second embodiment, in the first embodiment, the messages include at least one of a message promoting positive reappraisal, which is a type of subcategory of reappraisal, a message promoting refocusing on a plan, a message promoting a global perspective, and a message promoting positive refocusing.

[0133] This has the advantage that by presenting a message to the occupants, it becomes easier for them to re-examine their negative emotions from a different perspective, making it easier to suppress the negative emotions felt by the vehicle occupants, particularly the anxiety they may feel.

[0134] In the information presentation systems 100, 100A, and 100B according to the third aspect, in the first or second aspect, the detection unit 1 acquires bio-information of the occupant, and detects the occurrence of a negative emotion in the occupant based on the acquired bio-information.

[0135] This has the advantage that the occurrence of a negative emotion in an occupant is detected based on biometric information that may vary depending on the emotion felt by the occupant, making it easier to detect the occurrence of a negative emotion in an occupant with high accuracy.

[0136] In the information presentation systems 100, 100A, and 100B according to the fourth aspect, in the third aspect, the detection unit 1 further acquires situational information regarding the situation in which the vehicle is placed, and further detects the possibility of the occupant experiencing negative emotions and the causes of the occurrence of negative emotions based on the acquired situational information.

[0137] This has the advantage that it is possible to detect the occurrence of negative emotions in an occupant with higher reliability than detection based on the occupant's biological information.

[0138] In the information presentation system 100, 100A, 100B according to the fifth aspect, in any one of the first to third aspects, when the detection unit 1 detects the occurrence of a negative emotion in an occupant, it further executes a process of confirming with the occupant whether or not the occupant is harboring the negative emotion.

[0139] This makes it possible to confirm whether the occupant is actually feeling negative emotions, allowing information to be presented to the occupant and, for example, by feeding back the confirmation results, which can be used to improve the accuracy of detecting the occurrence of negative emotions in the occupant.

[0140] In the information presentation systems 100, 100A, and 100B according to the sixth aspect, in the fourth aspect, when the detection unit 1 detects the possibility of an occupant experiencing a negative emotion, it further executes a process of confirming with the occupant whether or not the occupant is experiencing the negative emotion.

[0141] This makes it possible to confirm whether the occupant is actually feeling negative emotions, allowing information to be presented to the occupant and, for example, by feeding back the confirmation results, which can be used to improve the accuracy of detecting the occurrence of negative emotions in the occupant.

[0142] In the information presentation system 100, 100A, 100B according to the seventh aspect, in any one of the first to sixth aspects, the processing unit 2 executes a process of presenting a message to the occupant when the detection unit 1 detects the occurrence of a negative emotion by the occupant while the vehicle is traveling.

[0143] This has the advantage that the influence on the driving of the vehicle caused by the occupants' negative emotions while the vehicle is traveling can be reduced, making it easier to assist the driving of the vehicle.

[0144] In the information presentation systems 100, 100A, and 100B according to the eighth aspect, in the seventh aspect, when the negative emotion is either anger or irritation, the processing unit 2 performs a process of presenting a message to the occupant after performing a process of promoting calming of the occupant's negative emotion.

[0145] This has the advantage that the message is presented to the occupant after attempting to calm negative emotions, such as strong anger or irritation, for which the effect of reevaluation in cognitive changes tends to be relatively small, making it easier to increase the effectiveness of presenting the message in suppressing the negative emotions felt by the occupant.

[0146] In the information presentation system 100, 100A, 100B according to the ninth aspect, in the seventh or eighth aspect, the processing unit 2 identifies a cause of the negative emotion based on at least one of the result of the self-monitoring of the occupant and situation information related to the situation of the vehicle. The processing unit 2 determines a message to be presented to the occupant based on the identified cause.

[0147] This has the advantage that an appropriate message can be determined depending on the cause of the negative emotion, making it easier to increase the effect of suppressing the negative emotions felt by the occupants by presenting the message.

[0148] In the information presentation systems 100, 100A, and 100B according to the tenth aspect, in any one of the seventh to ninth aspects, the processing unit 2 further executes a process for encouraging the occupant to relax.

[0149] This has the advantage that it becomes easier to divert the occupant's attention from the cause of the negative emotion, thereby making it easier to increase the effectiveness of the message in suppressing the negative emotion felt by the occupant.

[0150] In the information presentation system 100A according to an eleventh aspect, in any one of the first to tenth aspects, the processing unit 2 calculates characteristic information indicating characteristics related to the occurrence of negative emotions of the occupant based on history data that accumulates data related to the occurrence of negative emotions of the occupant detected by the detection unit 1 while the vehicle is traveling. When driving of the vehicle is terminated, the processing unit 2 executes a process of presenting a message determined based on the calculated characteristic information to the occupant.

[0151] This has the advantage that when driving the vehicle is finished, a message tailored to the occupant's characteristics is presented to the occupant, which is expected to improve the occupant's psychological skills in suppressing the occurrence of negative emotions.

[0152] In the information presentation system 100A according to the twelfth aspect, in the eleventh aspect, the processing unit 2 calculates past characteristic information based on a history of calculated characteristic information. When the processing unit 2 calculates the characteristic information, the processing unit 2 determines a message to be presented to the occupant based on the characteristic information and the past characteristic information.

[0153] This has the advantage that the message is determined based more on the occupant's past characteristics, which is expected to improve the occupant's psychological skills to suppress the occurrence of negative emotions.

[0154] In the information presentation system 100B according to the thirteenth aspect, in any one of the first to twelfth aspects, the processing unit 2 acquires future situation information related to a future situation in which the vehicle will be placed. When the processing unit 2 detects that the occupant may experience a negative emotion based on the acquired future situation information and past characteristic information, the processing unit 2 executes a process of presenting a message to the occupant.

[0155] This has the advantage that the message is presented to the occupant before he or she begins to feel negative emotions, making it easier to prevent the occupant from feeling negative emotions in advance.

[0156] In an information presentation method according to a fourteenth aspect, the occurrence of a negative emotion in a vehicle occupant is detected, and when the occurrence of a negative emotion in the occupant is detected, a process is executed to present to the occupant a message that encourages reevaluation of cognitive changes in response to the negative emotion.

[0157] This has the advantage that by presenting a message to the occupant, it becomes easier for the occupant to reconsider negative emotions from a different perspective, making it easier to suppress negative emotions felt by the vehicle occupants.

[0158] A program according to a fifteenth aspect causes one or more processors to execute the information presentation method according to the thirteenth aspect.

[0159] This has the advantage that by presenting a message to the occupant, it becomes easier for the occupant to reconsider negative emotions from a different perspective, making it easier to suppress negative emotions felt by the vehicle occupants. [Industrial Applicability]
