Description

The present disclosure relates to a psychological state guidance device and a mental state guidance method for guiding the psychological state of a subject to a comfortable state.

Techniques for inducing the psychological state of a subject are known. For example, Patent Literature 1 discloses a technique for promoting serotonin secretion and suppressing anger and excitement by guiding a driver to breathe in a regular rhythm by display or voice.

JP-A-2005-237456

However, in the technique disclosed in Patent Document 1, although it is possible to induce a state corresponding to "relaxed" among multiple types of comfortable psychological states, other comfortable psychological states such as "happiness" and "excitement" are possible. Navigating to a state presents a difficult problem.

In addition, when trying to make it possible to induce multiple types of comfortable psychological states, it is difficult to implement stimuli according to the current and/or desired psychological state without making it monotonous. be done. As an example, if a psychological state and a stimulus are directly linked such that a certain stimulus is performed in a certain psychological state, only fixed stimuli are performed for a specific psychological state, and the subject becomes easily bored. In this case, there is a risk that the effect of inducing the psychological state will be reduced.

One purpose of this disclosure is to make it easier to guide the subject's psychological state to any of a plurality of types of comfortable psychological states with different directions, and to prevent the stimulation that induces the psychological state from becoming monotonous. To provide a mental state guidance device and a mental state guidance method that enable

The above objects are achieved by the combination of features stated in the independent claims, and the subclaims define further advantageous embodiments of the disclosure. The symbols in parentheses described in the claims indicate the corresponding relationship with specific means described in the embodiments described later as one aspect, and do not limit the technical scope of the present disclosure. .

In order to achieve the above object, the psychological state induction device of the present disclosure provides a current mental state, a target mental state, and a current mental state and a target as target states, which are targeted psychological states of a subject. A target state identification unit (202) that identifies any of the states of the combination with the mental state of and an impression word determining unit (203, 203a) for determining a combination of a plurality of types of impression words representing the impression of the space estimated to be a space that matches the image of the combination of the plurality of types of impression words determined by the impression word determining unit. selection units (205, 205a) for selecting a spatial image, which is information representing the same combination, from a database (206) storing at least a plurality of types of spatial images; It comprises a stimulus determination unit (207, 207a) that determines a stimulus that is estimated to cause a stimulus, and a stimulus control unit (209, 209a) that presents the stimulus determined by the stimulus determination unit to the subject.

In order to achieve the above object, the mental state induction method of the present disclosure includes a current mental state, a target mental state, a target mental state, and a target mental state of a subject, which are executed by at least one processor. A target state identifying step for identifying a state or a combination of a current mental state and a target mental state; An impression word determination step of determining a combination of a plurality of types of impression words representing an impression of a space estimated to be desirable for comfort, and a combination of the plurality of types of impression words determined in the impression word determination step that matches the image. A selection step of selecting a spatial image, which is information representing space, from a database (206) storing at least a plurality of types of spatial images for the same combination, and presumed to evoke the spatial image selected in the selection step. and a stimulus control step of presenting the stimulus determined in the stimulus determination step to the subject.

According to these, since a stimulus presumed to evoke a spatial image is selected and presented, the spatial image is recollected by the presentation of this stimulus. The spatial image used for stimulus selection is information that represents a space that matches the image of a combination of multiple types of impression words, and the combination of multiple types of impression words is the target psychological state of the subject. It represents an impression of space that is estimated to be desirable for the subject to be comfortable with the condition. Therefore, by recollecting the spatial image, the psychological state of the subject is induced to a comfortable state. If the target state is different, the stimulus corresponding to the target state is selected and presented as described above, so that the target person's psychological state can be guided to any of a plurality of types of comfortable psychological states with different directions. can be made easier. In addition, the spatial image, which is information representing a space whose image matches the combination of multiple types of impression words, is selected from a database that stores at least multiple types of spatial images for the same combination, so that the same combination is not possible. A different spatial image can be selected. Thus, even for the same target state, the stimulus may vary depending on the spatial image selected. Therefore, stimuli are less likely to become monotonous. In addition, since the stimulus is less likely to become monotonous, the subject is less likely to become bored with the stimulus, making it easier to induce a psychological state through the stimulus. As a result, it is possible to easily guide the subject's psychological state to any of a plurality of types of comfortable psychological states with different directions, and to prevent the stimulus that induces the psychological state from becoming monotonous.

The DSM 21 is arranged, for example, on the upper surface of the instrument panel, with the near-infrared camera facing the driver's seat side of the vehicle. The DSM 21 uses a near-infrared camera to photograph the driver irradiated with near-infrared light from the near-infrared light source. The imaging range may be set to include at least the driver's head. An image captured by the near-infrared camera is image-analyzed by the control unit. The control unit detects the state of the driver based on the feature amount of the driver extracted by image analysis of the captured image.

The biosensor 22 measures the biometric information of the driver. The biological sensor 22 sequentially outputs the measured biological information to the HCU 20 . The biosensor 22 may be configured to be provided in the own vehicle, or may be configured to be provided in a wearable device worn by the driver. When the biosensor 22 is provided on the vehicle, it may be provided on the steering wheel, seat, or the like. When the biosensor 22 is provided in the wearable device, the HCU 20 may acquire the measurement result of the biosensor 22 via the NFCM 4, for example. Examples of biological information measured by the biological sensor 22 include respiration, pulse, and heartbeat.

Examples of the biosensor 22 include a pulse wave sensor that measures a heart rate or a pulse rate from a pulse wave waveform obtained by measurement. Another example is a respiration sensor that detects respiration movement in a non-contact manner using a Doppler sensor that uses Ghz-band microwaves. The breathing sensor may be a seat belt or a pressure sensor provided on the seat back. Moreover, when estimating respiration from a pulse wave, a pulse wave sensor may be used as a respiration sensor. Note that the biosensor 22 may be configured to measure biometric information other than respiration, pulse, and heartbeat. For example, the biosensor 22 may measure brain waves, heartbeat fluctuations, perspiration, body temperature, blood pressure, skin conductance, and the like.

The vibrator 23 is provided at a location that the driver comes into contact with, and gives vibration stimulation to the driver. In other words, a tactile stimulus is given. The vibrator 23 is a presentation device that presents stimulation. Vibration of the vibrator 23 is controlled by the HCU 20 . The vibrator 23 is provided, for example, on a member that comes into contact with the driver, such as a steering wheel of the vehicle, a driver's seat, or a wearable device worn by the driver. When the vibrator 23 is provided in the wearable device, it may be configured to receive an instruction to generate vibration from the HCU 20 via the NFCM 4, for example.

The illumination device 24 is provided at a position visible to the driver, and stimulates the driver with light emission. In other words, it provides a visual stimulus. The illumination device 24 is a presentation device that presents stimuli. A light-emitting device such as an LED may be used as the lighting device 24 . The illumination device 24 can switch the color of light emission. The lighting device 24 is controlled by the HCU 20 in timing of turning on and off and the color of light emitted.

The display device 25 displays information. The display device 25 is provided at a position visible to the driver, and provides the driver with display stimulation. In other words, it provides a visual stimulus. The display device 25 is a presentation device that presents stimuli. The display device 25 displays at least an image. The display device 25 may display text or the like in addition to images. The display of the display device 25 is controlled by the HCU 20 .

As the display device 25, for example, a meter MID (Multi Information Display), CID (Center Information Display), HUD (Head-Up Display) can be used. The meter MID is a display device provided in front of the driver's seat in the passenger compartment. As an example, the meter MID may be configured to be provided on the meter panel. CID is a display device arranged in the center of the instrument panel of the vehicle. The HUD is provided, for example, on an instrument panel inside the vehicle. The HUD projects a display image formed by the projector onto a predetermined projection area on the front windshield as a projection member. The image light reflected by the front windshield to the interior of the vehicle is perceived by the driver seated in the driver's seat. As a result, the driver can visually recognize the virtual image of the display image formed in front of the front windshield overlapping a part of the foreground. The HUD may be configured to project the display image onto a combiner provided in front of the driver's seat instead of the front windshield.

The audio output device 26 provides the driver with sound stimulation. In other words, auditory stimulation is provided. The audio output device 26 is a presentation device that presents stimuli. Sounds output from the audio output device 26 include music, environmental sounds, and the like. Music may include BGM. An environmental sound may be a sound that reproduces a specific environment. As the audio output device 26, for example, an audio speaker that outputs audio may be used.

The user input device 27 accepts input from the user. The user input device 27 may be an operation device that receives operation input from the user. The operation device may be a mechanical switch or a touch switch integrated with the display device 25 . It should be noted that the user input device 27 is not limited to an operation device that receives operation input as long as it is a device that receives input from the user. For example, it may be a voice input device that receives command input by voice from the user.

The HCU 20 is mainly composed of a microcomputer having a processor, memory, I/O, and a bus connecting them. The HCU 20 executes a control program stored in the memory to execute various types of processing such as processing related to guidance of the driver's mental state (hereinafter referred to as mental state guidance-related processing). This HCU 20 corresponds to a mental state guidance device. Memory, as used herein, is a non-transitory tangible storage medium for non-transitory storage of computer-readable programs and data. A non-transitional physical storage medium is implemented by a semiconductor memory, a magnetic disk, or the like. In addition, the details of the psychological state induction related processing in the HCU 20 will be described below.

<Schematic configuration of HCU 20>
Next, a schematic configuration of the HCU 20 will be described with reference to FIG. 2 . As shown in FIG. 2, the HCU 20 includes a user input acquisition unit 201, a target state identification unit 202, an impression word determination unit 203, a map storage unit 204, a selection unit 205, a spatial image database (hereinafter referred to as DB) 206, a stimulus determination unit 207, a stimulus DB 208, a stimulus control unit 209, and a notification processing unit 210 as functional blocks. Execution of the processing of these functional blocks by the computer corresponds to execution of the mental state guidance method. A part or all of the functions executed by the HCU 20 may be configured as hardware using one or a plurality of ICs or the like. Also, some or all of the functional blocks provided by the HCU 20 may be implemented by a combination of software executed by a processor and hardware members.

The user input acquisition unit 201 acquires information about inputs received by the user input device 27 . For example, when the user input device 27 receives input of the driver's current state of mind, the user input acquisition unit 201 acquires information on the current state of mind. When the user input device 27 receives an input of the target mental state of the driver, the user input acquisition unit 201 acquires information on the target mental state. When the user input device 27 receives an input of a combination of the driver's current mental state and the target mental state, the user input acquisition unit 201 selects the combination of the current mental state and the target mental state. Get combination information. In addition, when an operation input is received by the user input device 27, the user input acquisition unit 201 acquires information about this operation input.

The target state identification unit 202 identifies the current state of mind, the target state of mind, and the combination of the current state of mind and the target state of mind as the target state of mind for the driver (hereinafter referred to as the target state). Identify one of the states (hereinafter referred to as the target transition state). The processing by the target state identification unit 202 corresponds to the target state identification step. As shown in FIG. 3, the psychological states handled in this embodiment are classified by a ring model representing the psychological states on two axes, the axis of pleasure and displeasure and the axis of activity and inactivity. This torus model is the so-called Russell's torus model. The activity-inactivity axis may be rephrased as the arousal-sedation axis. In the following description, psychological states classified by the ring model are exemplified by "frustrated", "depressed", "excited", "happy", and "relaxed" shown in FIG.

"Irritated" is a psychological state of both displeasure and activity. "Shombori" is a psychological state of high discomfort but low activity. “Wakuwaku” is a psychological state in which both pleasure and activity are high. "Happiness" is a state of mind with high pleasure and neither high nor low activity. "Relaxation" is a state of mind in which pleasure is high but activity is low. "Irritated" and "Irritated" are psychological states in the unpleasant direction. "Excited", "Happy", and "Relaxed" are psychological states in the direction of comfort. In the present embodiment, "frustrated", "dejected", "excited", "happy", and "relaxed" will be described as examples of psychological states, but they are not necessarily limited to these. For example, other psychological states such as "fear", "disgust", and "surprise" may be handled. "Fear" is a psychological state in which both discomfort and activity are high, and activity is higher than that of "frustration". “Anaerobic” is a psychological state in which both discomfort and activity are high, and discomfort is higher than “irritability”. "Surprise" is a highly active psychological state in which neither pleasure nor displeasure is high.

The target state identification unit 202 may identify the target state based on the driver's feature quantity extracted by the DSM 21, for example. As an example, the current state of mind may be specified based on the characteristic amount of the facial expression for each state of mind. The target state identification unit 202 may identify the target state based on the driver's biological information measured by the biological sensor 22, for example. As an example, the current state of mind may be identified based on the value of characteristic biometric information for each state of mind. The target state identification unit 202 may identify the target state based on voice data of an input received by the user input device 27 as a voice input device. As an example, the current state of mind may be identified based on the feature amount of speech for each state of mind.

The target state identification unit 202 may identify the target state based on the driver's schedule information acquired from the driver's mobile terminal by NFCM4, for example. The driver's schedule can be obtained from the schedule application of the mobile terminal. As an example, the target mental state may be specified by estimating the driver's target mental state based on the immediately following schedule. For example, if the immediate schedule is a meeting and going to bed, the target state of mind may be specified as "relaxed." Also, if the immediate schedule is to meet with a person in private, the target state of mind may be specified as "excited."

The target state identification unit 202 may identify a combination state of the current mental state and the target mental state by combining the plurality of means described above. Further, when the user input acquiring unit 201 acquires information about the target state, the target state specifying unit 202 may specify the target state based on this information. In this case, among the current state of mind, the target state of mind, and the target state of transition, the state of mind whose input is received by the user input device 27 is specified as the target state.

In the present embodiment, as described above, a plurality of types of means have been described as means for identifying the target state, but a configuration using only some of them may be employed. In this case, the configuration related to the unused means may be omitted from the mental state guidance system 1 .

Based on the target state specified by the target state specifying unit 202, the impression word determination unit 203 selects a combination of multiple types of impression words representing the impression of the space that is estimated to be desirable for the driver to be comfortable with respect to the target state. to decide. The processing in this impression word determination unit 203 corresponds to the impression word determination step. As an example, using a map (hereinafter referred to as a conversion map) for converting the target state into an impression word combination stored in the map storage unit 204, the combination of impression words from the target state specified by the target state specifying unit 202 can be obtained. should be specified. A non-volatile memory, for example, may be used as the map storage unit 204 . The conversion map is a correspondence relationship between a target state and a combination of multiple types of impression words that express the impression of a space that is estimated to be desirable for the comfort of the driver in the target state.

Here, impression words will be explained. An impression word is a word expressing an impression felt when viewing an image or imagining a space. For example, there are impression words such as "beautiful", "cute", "modern", "classic", "dynamic", "static", "simple", "lively", "modern", and "soft". In the present embodiment, the case where the above ten kinds of impression words are used as impression words will be described as an example. "Dynamic" includes impressions of movement such as dynamic, violent, and changing. "Static" includes the impression of being calm and motionless. "Simple" includes the impression of being simple. In addition, the ten types of impression words used in this embodiment include five sets of impression words having an antonym relationship. The first is "beautiful" and "cute". The second is "modern" and "classic." The third is "dynamic" and "static". The fourth is "simple" and "lively". The fifth is "modulated" and "fluffy".

Next, the conversion map stored in the map storage unit 204 will be explained. For example, the conversion map generated as follows is stored in the map storage unit 204 . Here, a method for generating a change map will be described. First, for each target state such as the subject's current state of mind, the target state of mind, and the target state of transition, the subject is asked to answer the desired space for the subject to be comfortable with respect to the target state. Specifically, the subject is asked to select a spatial image that matches the desired space from images representing various spaces (hereinafter referred to as spatial image). Examples of the spatial image include an image of a beautiful sea, an image of a cat with fluffy fur, and the like. For example, 1500 subjects are asked to select from 1000 spatial images. In addition, the subjects were asked to answer multiple impression words that they imagined from the selected spatial image. Then, a combination of impression words is given to each spatial image by statistical processing. In the statistical processing, a combination of impression words with which there are many responses to the spatial image and confirmed by regression analysis to have a high correlation with the spatial image may be added. A conversion map is generated based on the correspondence relationship between the target state obtained in this way and the combination of the spatial image image and the impression word.

Here, an example of the correspondence relationship between the target state and the combination of impression words in the conversion map will be shown. For example, an example of the correspondence relationship between the target transition state and the combination of impression words may be as shown in FIG. For the target transition state of the combination of the current state of mind "depressed" and the target state of mind "excited", the impression words "cute" and "dynamic" may be associated. For the target transition state of the combination of the current state of mind "shockbori" and the target state of mind "happiness", the impression words "dynamic" and "fluffy" may be associated. The impression words "beautiful" and "static" may be associated with the target transition state of the combination of the current state of mind "shockbori" and the target state of mind "relax".

Although the current state of mind can be specified, the conversion map preferably also includes the correspondence relationship between the current state of mind and the combination of impression words in case the target state is unknown. An example of the correspondence relationship between the current state of mind and the combination of impression words may be as shown in FIG. Impression words "simple" and "soft" should be associated with the current state of mind "frustrated". Impression words "cute" and "fluffy" may be associated with the current state of mind "depressed".

Although the target state of mind can be specified, the conversion map preferably also includes the correspondence relationship between the target state of mind and the combination of impression words in case the current state of mind is unknown. FIG. 6 shows an example of the correspondence relationship between the target psychological state and the combination of impression words. Impression words "dynamic" and "lively" may be associated with the target psychological state "excited". The target psychological state "happiness" may be associated with the impression words "cute" and "fluffy." Impression words "beautiful" and "simple" may be associated with the target psychological state "relaxed".

It should be noted that the conversion map may be configured to be stored in the map storage unit 204 generated according to sex and generation. In this case, in addition to specifying the target state, the gender and generation of the driver may also be specified, and the combination of target words may be determined using a conversion map suitable for the gender and generation of the driver. According to this, it is possible to more accurately determine a combination of a plurality of types of impression words representing impressions of a space that are estimated to be desirable for the comfort of the driver in relation to the target state, for each gender and generation of the driver. becomes possible. The gender and generation of the driver may be specified based on the driver's feature quantity extracted by the DSM 21 .

Further, the conversion map may be configured to be stored in the map storage unit 204 after being generated for an individual. According to this, it becomes possible to more accurately determine a combination of a plurality of types of impression words representing an impression of a space that is estimated to be desirable for making the driver comfortable in the target state. A conversion map suitable for an individual may be generated by the generation method described above, for example, using an individual as a subject. In this case, the server may generate a conversion map suitable for the individual by exchanging with the server via the display device and the input device of the portable terminal in the same manner as described in the generation method described above. Then, the HCU 20 may obtain the conversion map from this server via a communication module connectable to a public communication network. Communication with the server may be performed via the display device 25 and the user input device 27 .

The selection unit 205 stores a spatial image, which is information representing a space whose image matches the combination of the plurality of types of impression words determined by the impression word determination unit 203. At least a plurality of types of spatial images are stored for the same combination. selected from the spatial image DB 206 . The processing in the selection unit 205 corresponds to the selection step. A non-volatile memory may be used as the spatial image DB 206 . As the spatial image stored in the spatial image DB 206, the spatial image used for generating the transformation map may be used. A combination of impression words is given to this spatial image.

The selection unit 205 extracts a spatial image image to which a combination of a plurality of types of impression words determined by the impression word determination unit 203, for example, is added. Then, a playlist is created in which the plurality of types of extracted spatial images are put together. The selection unit 205 sequentially selects spatial images from this playlist. Spatial images may be selected randomly from the playlist. According to this, the stimulation described later becomes less monotonous. As described above, the selection unit 205 represents a space that matches the combination of the plurality of types of impression words determined by the impression word determination unit 203 based on the correspondence relationship between the combination of the plurality of types of impression words and the spatial image. Select a spatial image.

The spatial image image stored in the spatial image DB 206 is not limited to the spatial image image used for generating the transformation map. For example, based on the spatial image used to generate the transformation map, a new similar spatial image may be added by machine learning. When adding a similar spatial image, the combination of impression words similar to those of the original spatial image may be added.

Also, in this embodiment, a case where a spatial image is used as the spatial image will be described as an example, but the spatial image is not limited to the spatial image. For example, a sentence representing a space that matches the image of a combination of multiple types of impression words may be used.

A stimulus determination unit 207 determines a stimulus estimated to evoke the spatial image selected by the selection unit 205 . The processing in this stimulus determination unit 207 corresponds to a stimulus determination step. As an example, the impression given to the spatial image selected by the selection unit 205 is calculated using the correspondence relationship between the combination of impression words and the mode of stimulation stored in the stimulation DB 208 (hereinafter referred to as the stimulus correspondence relationship). A stimulus can be determined from a combination of words. A non-volatile memory may be used as the stimulus DB 208 . In the correspondence relationship between the combination of impression words and the mode of stimulation, the combination of impression words is associated with a stimulus presumed to evoke the space imaged from the combination. The combination of impression words given to the spatial image is a combination of impression words that are highly likely to be imaged from the spatial image. Therefore, it is possible to evoke a spatial image by a stimulus associated with such a combination of impression words.

The stimulus determined by the stimulus determination unit 207 may be a stimulus type and a stimulus mode. The number of types of stimulus determined by the stimulus determination unit 207 is preferably plural, but may be one. In this embodiment, an example will be described in which the stimulus determination unit 207 determines, for one spatial image, multiple types of stimuli that are estimated to evoke the spatial image selected by the selection unit 205 . Types of stimuli include "image", "lighting", "music", "environmental sound", "vibration", "aroma", "wind", and "hot and cold stimulus".

The combination of stimulus types may be the same regardless of the combination of impression words, or may be different according to the combination of impression words. When different combinations of types of stimuli are used depending on the combination of impression words, the type of stimulus estimated to evoke the space imaged from the impression words may be selected. For example, a combination of impression words "cute" and "fluffy" will be taken as an example. It is presumed that the space imaged by "cute" is easily conceived by cute "images", "music", "lighting" and the like. It is presumed that the space imaged by "soft" can be easily evoked by soft "wind", "thermal stimulation", "image", "music", "environmental sound", etc. On the other hand, "vibration" is presumed to be difficult to recall. Therefore, the combination of impression words "cute" and "fluffy" should not be associated with "vibration" in the stimulus correspondence relationship.

If the type of stimulus determined by the stimulus determination unit 207 is "image", the type of image may be selected. For example, for a combination of impression words "cute" and "fluffy," an image containing a cute and fluffy animal may be determined as a mode of stimulation. As for the "image", a spatial image image may be used. For example, for a combination of impression words "cute" and "fluffy", a spatial image to which this combination is assigned may be determined as a mode of stimulation.

If the type of stimulus determined by the stimulus determination unit 207 is "music" or "environmental sound," the types of music and environmental sound may be selected. For example, for a combination of impression words including "dynamic," fast-paced music and environmental sounds may be determined as stimulus modes. If the mode of stimulus determined by the stimulus determination unit 207 is "illumination", the color of light emission may be used. For example, for a combination of impression words including "static", a cool luminescence color may be determined as a mode of stimulation. If the mode of stimulation determined by the stimulation determination unit 207 is "vibration", the intensity of the vibration may be used. For example, for a combination of impression words including "dynamic," strong vibration may be determined as the mode of stimulation.

If the mode of stimulation determined by the stimulation determination unit 207 is "aroma", the type of aroma may be selected. For example, for a combination of impression words including "cute", a sweet fragrance may be determined as the mode of stimulation. If the stimulus mode determined by the stimulus determination unit 207 is "wind", the volume of the conditioned air may be used. For example, for a combination of impression words including "static", a slightly weaker volume of conditioned air may be determined as the mode of stimulation. If the mode of stimulation determined by the stimulation determination unit 207 is "warm/cold stimulation," the temperature of the air-conditioned air may be used. For example, for a combination of impression words including "static", air-conditioning air with a lower temperature may be determined as a mode of stimulation.

The mode of stimulation determined by the stimulus determination unit 207 may be the mode of change in stimulation. For example, in the stimulus correspondence relationship, a combination of impression words including an impression word related to change may be associated with a mode of stimulus change that matches the impression word related to change. For example, impression words related to change include "dynamic," "static," "modern," and "fluffy." As an example, when "dynamic" is included, a mode may be adopted in which fluctuation is caused to change the brightness of "illumination". On the other hand, when it includes "static", it may be a form that does not cause fluctuations. In the case of including "modularity", the time required for constant change when changing the lightness of "illumination" may be short. On the other hand, when "fluffy" is included, the time required for constant change when changing the lightness of "illumination" may be set long. Here, an example of changing the mode of "lighting" is shown, but it is also possible to change the mode of stimulation other than "lighting".

The stimulus control unit 209 presents the stimulus determined by the stimulus determination unit 207 to the driver. The processing in this stimulus control unit 209 corresponds to the stimulus control step. When the stimulus determination unit 207 determines multiple types of stimuli, the stimulus control unit 209 presents the multiple types of stimuli to the driver. The stimulus control unit 209 causes the type of stimulus determined by the stimulus determination unit 207 to be presented in the mode of the stimulus determined by the stimulus determination unit 207 . For example, when the types of stimuli in the stimulus determination unit 207 are "image", "environmental sound", "lighting", and "aroma", "image", "environmental sound", "lighting", and "aroma" The stimulus determined by the stimulus determination unit 207 is presented to the driver. After the playlist is once created by the selection unit 205, a spatial image is selected from the playlist at regular intervals until a new target state is specified by the target state specifying unit 202, and the spatial image is selected. It is assumed that the stimulus control unit 209 presents stimuli corresponding to images. The stimulus control unit 209 presents the stimulus determined by the stimulus determination unit 207 to the driver, thereby providing the driver with a space that is estimated to evoke the spatial image selected by the selection unit 205 . Below, this space is called a provision space.

The stimulus control unit 209 may control the display device 25 to present the “image”. “Lighting” may be presented by controlling the lighting device 24 . "Music" and "environmental sounds" may be presented by controlling the audio output device 26. FIG. "Vibration" may be presented by controlling the vibrator 23 . "Aroma" may be presented by sending an instruction to the air conditioning control ECU 30 to control the aroma unit 32 . "Wind" and "warm/cold stimulus" may be presented by sending an instruction to the air conditioning control ECU 30 to control the air conditioning unit 31 . Note that the “warm/cold stimulus” may be presented by controlling a heater provided on the seat.

When the stimulus control unit 209 presents the “aroma”, it is preferable to intermittently present it as shown in FIG. Moreover, in order to prevent the driver from becoming accustomed to the "fragrance", it is preferable to change the type of the "fragrance" after a certain period of time has elapsed since the "fragrance" was presented. FIG. 7 shows the presentation timing of stimuli. FIG. 7 shows, as an example, a case where the stimuli are "image", "environmental sound", "illumination", and "aroma".

The stimulus control unit 209 presents the stimulus determined by the stimulus determination unit 207 as being presumed to evoke the spatial image selected by the selection unit 205, and selects the spatial image by the selection unit 205. When an impression word related to change is included in the combination of multiple types of impression words used for selection, the stimulus is presented so that a change matching the impression word related to change occurs in the stimulus. It is preferable to let

When lighting and sound are presented as stimuli determined by the stimulus determining unit 207, the stimulus control unit 209 preferably fluctuates the lighting in accordance with the sound pressure of the sound. According to this, the receptivity of each stimulus to the driver is enhanced by interlocking the changes of the lighting and the sound. As a result, the effect of inducing the psychological state is enhanced. The sounds referred to here include "music", "environmental sounds", and the like.

When lighting is presented as the stimulus determined by the stimulus determination unit 207, the stimulus control unit 209 uses the current psychological state and target psychological state of the driver (i.e., the target person) identified by the target state identification unit 202. Preferably, the illumination is periodically oscillated in response to at least one of the conditions. For example, if only one of the current state of mind and the target state of mind can be specified, the illumination may be periodically fluctuated according to the one state of mind. Also, if both the current state of mind and the target state of mind can be specified, the illumination may be periodically fluctuated according to both states of mind. For example, in the first half, the illumination may be fluctuated with a period corresponding to the current state of mind, and in the second half, the illumination may be fluctuated with a period corresponding to the target state of mind. Periodically fluctuating the illumination refers to changing the brightness like a change of a sine wave (that is, a sine wave). In other words, it means that the illumination gradually brightens to the maximum luminance, then gradually darkens to the minimum luminance, and then gradually brightens again. As an example,

For example, if the current psychological state is on the uncomfortable side, such as "frustrated" or "dejected," the illumination may be slowly fluctuated, for example, at intervals of 6 seconds or longer. If the target psychological state is an active mental state such as "excited," the illumination may be fluctuated at a fast tempo of, for example, a period of 3 seconds or less. In the case of a combination of the current state of mind "shockbori" and the target state of mind "wakuwaku", the lighting is slowly swayed in the first half, for example, with a period of 6 seconds or more, and in the second half, the lighting is set at a fast tempo, for example, in a period of 3 seconds or less. Shake it. For example, if the current state of mind is "frustrated" or "depressed", the lighting may be fluctuated at intervals of 6 seconds or more and 10 seconds or less. If the target psychological state is "excited", the lighting fluctuation cycle should be set to 3 seconds or less. If the target psychological state is "happiness", the cycle of lighting fluctuation should be 3 seconds or more and 8 seconds or less. If the target state of mind is "relaxed," the cycle of lighting fluctuation should be set to 8 seconds or longer.

When the stimulus control unit 209 presents the illumination and the image as the stimulus determined by the stimulus determination unit 207, it is preferable to present the illumination of the light of the color extracted from the image. The illumination of the light of the color extracted from the image does not have to match the color extracted from the image completely, and may be the most similar color among the colors that can be emitted by the illumination device 24 . According to this, by unifying the colors of the lighting and the image, the receptivity of each stimulus to the driver is increased. As a result, the effect of inducing the psychological state is enhanced.

The stimulation control section 209 may change the provision space according to the input received by the user input device 27 . For example, the images and music that are sequentially presented at regular intervals may be advanced or returned to the previous image or music before the specified period of time elapses according to the operation input. This is called a skip function. In addition, according to the operation input, fragrance may be generated or may be stopped. In addition, the stimulus control unit 209 may be configured to learn the driver's preferences according to the input when the user input device 27 receives an input from the driver that selects likes and dislikes regarding the provided space. As an example, if the driver's favorite provided space (that is, stimulus) for each target state is learned by supervised learning, where the provided space selected as a favorite is correct and the provided space selected as disliked is incorrect. good. The learning results may be used to increase the frequency of presenting stimuli such as spatial image images, music, etc., that suit the driver's taste.

These inputs may be received by a user input device 27 as a touch switch integrated with the display device 25, for example. Here, an example of a user interface screen for increasing the acceptability of the provided space will be shown using FIG. A in FIG. 8 is a button display for returning music and images in the skip function. B in FIG. 8 is a button display for advancing music and images in the skip function. C in FIG. 8 is a button display for temporarily stopping the reproduction of music and images in the skip function. D in FIG. 8 is a button display for instructing the start and presentation of fragrance generation. E in FIG. 8 is a button display for selecting what you like about the provided space. F in FIG. 8 is a button display for selecting dislike about the provided space. A spatial image is displayed in the IMG of FIG.

The notification processing unit 210 makes notification to the driver. When causing the stimulus control unit 209 to present a stimulus, the notification processing unit 210 preferably causes the stimulus control unit 209 to make a notice indicating why the stimulus is presented (hereinafter referred to as presentation reason notice). According to this, it becomes possible to reduce the driver's sense of incongruity with respect to the provided space. The reason for presentation may be notified by display on the display device 25 or by voice output from the voice output device 26 . For example, in the case of audio output, it is sufficient to output audio such as "I will provide a quiet and beautiful space for you to relax." In the case of display, it is preferable to use a display with low visual cognitive load, as shown in FIG. The presentation reason notification may be displayed, for example, on the user interface screen described above.

FIG. 9 is a display example of the presentation reason notification when the target state is the target transition state. As shown in FIG. 9, as the presentation reason notification, a mark indicating the current state of mind and a mark indicating the target state of mind may be displayed. This mark may be, for example, a mark that expresses the state of mind with facial expressions. Also, marks may be placed on the ring model so that the mental state can be easily understood. Alternatively, an arrow may be displayed from the mark indicating the current state of mind to the mark indicating the target state of mind. This makes it easier to distinguish and recognize the mark indicating the current state of mind from the mark indicating the target state of mind. If the target state is the current state of mind, the mark indicating the target state of mind may be omitted. The direction of the arrow may be displayed so as to point in the comfortable direction with the mark indicating the current state of mind as the starting point. If the target state is the target state of mind, the mark indicating the current state of mind may be omitted. The direction of the arrow may be displayed so that the mark indicating the target psychological state is directed from the unpleasant direction as the starting point.

<Mental State Guidance Related Processing in HCU 20>
Next, an example of the flow of psychological state induction related processing in the HCU 20 will be described using the flowchart of FIG. 10 . The flowchart of FIG. 10 may be configured to be started, for example, when a switch (hereinafter referred to as a power switch) for starting the internal combustion engine or motor generator of the own vehicle is turned on. In addition, in the case of a configuration in which the function for executing the psychological state guidance related process can be switched on/off via the user input device 27, the function for executing the psychological state guidance related process may be turned on. The configuration may be added to the conditions.

First, in step S1, the target state identification unit 202 identifies the target state. In step S2, the impression word determination unit 203 determines a combination of multiple types of impression words from the target state specified in S1. In step S3, the selection unit 205 extracts the spatial image to which the combination of the plurality of types of impression words determined in S2 is added. Then, a playlist is created in which the plurality of types of extracted spatial images are put together.

In step S4, the selection unit 205 randomly selects one spatial image from the playlist created in S3. In step S5, the stimulus determination unit 207 determines a stimulus from a combination of impression words given to the spatial image selected in S4. In step S6, the stimulus control unit 209 presents the stimulus determined in S5 to the driver.

In step S7, when the user input device 27 receives an input to skip the current provision space for the provision space (YES in S7), the process returns to S4 and repeats the processing. On the other hand, if an input to skip has not been received (NO in S7), the process proceeds to step S8. The skip referred to here may be proceeding to the next provision space or returning to the previous provision space. In order to proceed to the next provided space, one new spatial image may be randomly selected in S4. When returning to the previous provided space, the spatial image selected last time in S4 may be selected.

In step S8, if it is time to end the psychological state guidance related processing (YES in S8), the mental state guidance related processing ends. On the other hand, if it is not the end timing of the psychological state induction related process (NO in S8), the process proceeds to step S9. As an example of the end timing of the psychological state guidance related processing, there are the fact that the power switch of the own vehicle is turned off, the function of executing the mental state guidance related processing is switched off, and the like.

In step S9, if the current provision space has ended (YES in S9), the process returns to S4 and repeats the process. On the other hand, if the current provision space has not ended (NO in S9), the process returns to S6 and repeats the process. The provided space may end after a certain period of time from the start of the stimulus that constitutes the provided space.

<Summary of Embodiment 1>
According to the configuration of Embodiment 1, since a stimulus that is estimated to evoke a spatial image is selected and presented, the spatial image is recollected by the presentation of this stimulus. The spatial image used for stimulus selection is information representing a space that matches a combination of multiple types of impression words. It represents the impression of a space that is estimated to be desirable for comfort. Therefore, by recollecting the spatial image, the driver's psychological state is guided to a comfortable state. In addition, since the stimulus corresponding to the target state is selected and presented for each target state as described above, it is easy to guide the driver's psychological state to any of a plurality of types of comfortable psychological states with different directions. Become. Moreover, since the spatial image is randomly selected from the spatial image DB 206 that stores at least a plurality of types of spatial images for the same combination of impression words, different spatial images can be selected even for the same combination. Thus, even for the same target state, the stimulus may vary depending on the spatial image selected. Therefore, stimuli are less likely to become monotonous. In addition, since the stimuli are less likely to become monotonous, the driver is less likely to become bored with the stimuli, making it easier to induce a psychological state through the stimuli. As a result, it is possible to easily guide the subject's psychological state to any of a plurality of types of comfortable psychological states with different directions, and to prevent the stimulus that induces the psychological state from becoming monotonous.

According to the configuration of Embodiment 1, since impression words are used, it is possible to easily determine and control multiple types of stimuli effective for inducing a psychological state. This is because the impression words are abstracted, so that it is easy to link multiple types of stimulus modes that evoke the same image.

Further, according to the configuration of the first embodiment, it is possible to use the target transition state as the target state. The target transition state is a combination of the current state of mind and the target state of mind. Therefore, by using the target transition state, it is possible to quickly induce the target state of mind from the current state of mind. become.

In addition, according to the configuration of the first embodiment, it is possible to induce the driver's state of mind to be in a comfortable state of mind while maintaining a stable state of mind. This effect will be described with reference to FIG. In FIG. 11, when the target state is a combination of the current state of mind "depressed" and the target state of mind "wakuwaku", the combination of impression words "kawaii" and "dynamic" corresponding to this combination is displayed. An example of the case where a certain target person is presented with a space to be filled will be shown. Levels 1 to 5 on the vertical axis of the graph in FIG. 11 are psychological state levels. 3 is the standard level.

As shown in FIG. 11, the current state of mind "shocked" has changed from level 4 to level 3 and is improving. On the other hand, the targeted psychological state of "wakuwaku" has improved from level 2 to level 3. In addition, regarding psychological states other than the target psychological state, "happiness" and "frustration" did not change, and "relaxation" improved. In this way, it is possible to guide the target person to the target psychological state and maintain a stable state that does not increase the unpleasant psychological state.

(Embodiment 2)
In the above-described embodiment, when the target state is the target transition state, a configuration is shown in which a combination of multiple types of target words associated with the combination of the current state of mind and the target state of mind is used. However, it is not necessarily limited to this. For example, when the target state is the target transition state, a configuration using a combination of multiple types of target words associated with each combination of the current state of mind and the target state of mind (hereinafter referred to as an embodiment 2) may be used.

An example of the second embodiment will be described below with reference to the drawings. The mental state guidance system 1 of the second embodiment is the same as the mental state guidance system 1 of the first embodiment except that the HCU 20a is replaced with the HCU 20a.

As shown in FIG. 12, the HCU 20a includes a user input acquisition unit 201, a target state identification unit 202, an impression word determination unit 203a, a map storage unit 204a, a selection unit 205a, a spatial image database (hereinafter referred to as DB) 206, a stimulus determination unit 207a, a stimulus DB 208, a stimulus control unit 209a, and a notification processing unit 210 as functional blocks. The HCU 20a is the same as the HCU 20 of the first embodiment, except that the processing when the target state is the target transition state is different. This difference will be described below. It should be noted that the HCU 20a also corresponds to the mental state guidance device. Execution of processing of these functional blocks by a computer also corresponds to execution of the mental state guidance method.

The impression word determining unit 203a determines the current psychological state and the target psychological state from the state of the combination of the current mental state and the target mental state identified by the target state identifying unit 202 (that is, the target transition state). A combination of a plurality of types of impression words is determined for each state. The processing in this impression word determination unit 203a also corresponds to the impression word determination step. Similar to the impression word determination unit 203, the impression word determination unit 203a uses the conversion map stored in the map storage unit 204a to determine impression words for each of the current state of mind and the target state of mind. Just specify the combination. In the conversion map stored in the map storage unit 204a, the correspondence relationship between the target transition state and the combination of impression words may be omitted.

The selection unit 205a selects a spatial image, which is information representing a space that matches the combination of multiple types of impression words for each of the current psychological state and the target psychological state determined by the impression word determination unit 203a. , from the spatial image DB 206 . The processing in the selection unit 205a also corresponds to the selection step. The selection unit 205 may extract a spatial image image to which a combination of multiple types of impression words is given for each of the current mental state and the target mental state. Similar to the selection unit 205, the selection unit 205a may extract the spatial image image to which the combination of the plurality of types of impression words determined by the impression word determination unit 203a is added. Then, a playlist is created for each, and a spatial image can be selected from each playlist.

The stimulus determination unit 207a selects the stimulus estimated to evoke a spatial image of the current mental state and the stimulus estimated to evoke a spatial image of the target mental state selected by the selection unit 205a. Determine each. The process in this stimulus determination unit 207 also corresponds to the stimulus determination process. Similar to the stimulus determination unit 207, the stimulus determination unit 207a uses the stimulus correspondence stored in the stimulus DB 208 to select a stimulus from a combination of impression words given to the spatial image selected by the selection unit 205a. You just have to decide.

The stimulus control unit 209a causes the driver to first present the stimulus that is estimated to evoke a spatial image of the current psychological state determined by the stimulus determination unit 207a, and then determines by the stimulus determination unit 207a. Then, the driver is presented with a stimulus that is presumed to evoke a spatial image of the target psychological state. For example, the stimulus control unit 209a presents a plurality of spatial images of stimuli estimated to evoke a spatial image of the current psychological state, and then evokes a spatial image of the target mental state. An estimated stimulus may be presented. A plurality of spatial images refers to a plurality of selections of spatial images sequentially selected from the playlist. The processing in this stimulus control unit 209a also corresponds to the stimulus control step.

According to the configuration of the second embodiment, after inducing the driver's mental state with a stimulus that is presumed to evoke a spatial image of the current mental state, it is presumed that the spatial image of the target mental state will be recollected. The driver's psychological state is induced by the stimulus given. Therefore, it is possible to suppress abrupt changes in the driver's mental state compared to the case of inducing the driver's mental state with a stimulus that is presumed to evoke a spatial image of the combination of the current mental state and the target mental state. be possible. Therefore, it is possible to make the driver less likely to feel a sense of incongruity, and to induce the driver's state of mind naturally.

(Embodiment 3)
In the above-described embodiment, the case of using a combination of two types of impression words as a combination of impression words associated with the target state in the conversion map was taken as an example, but this is not necessarily the case. For example, a configuration using a combination of three types of impression words may be used.

Here, an example of the correspondence relationship between the target state and the combination of impression words in the conversion map according to the third embodiment will be shown. For example, an example of the correspondence relationship between the target transition state and the combination of impression words may be as follows. Impression words "cute", "fluffy", and "dynamic" may be associated with the target transition state of the combination of the current state of mind "depressed" and the target state of mind "excited". Impression words "beautiful", "dynamic", and "soft" may be associated with the target transition state of the combination of the current psychological state "shy" and the target psychological state "happiness". Impression words "beautiful", "static", and "simple" may be associated with the target transition state of the combination of the current state of mind "depressed" and the target state of mind "relaxed".

Impression words "beautiful", "dynamic", and "lively" may be associated with the target transition state of the combination of the current psychological state "irritated" and the target psychological state "excited". Impression words "beautiful", "simple", and "soft" may be associated with the target transition state of the combination of the current state of mind "frustration" and the target state of mind "happiness". Impression words "beautiful", "simple", and "classic" may be associated with the target transition state of the combination of the current state of mind "irritated" and the target state of mind "relaxed".

According to the configuration of the third embodiment, since the number of types of impression words included in the combination of impression words increases, a space more suitable for the space presumed to be desirable for making the target person comfortable with respect to the target state is provided. becomes possible. As a result, the psychological state can be induced with higher accuracy.

(Embodiment 4)
In the above-described embodiment, the configuration in which the HCU 20 and the HCU 20a are responsible for the psychological state guidance related processing was shown, but the configuration is not necessarily limited to this. For example, the HCUs 20 and 20a and another ECU may be responsible for the psychological state induction related processing, or the other ECU may be responsible for the psychological state induction related processing.

(Embodiment 5)
In the above-described embodiment, an example in which the driver is the target person was shown, but this is not necessarily the case. For example, a fellow passenger in a vehicle other than the driver may be the subject. In this case, changes such as identifying the subject state of the fellow passenger from the image of the fellow passenger captured by an indoor camera other than the DSM 21 may be made.

(Embodiment 6)
In the above-described embodiment, the mental state guidance system 1 is used in a vehicle, but the configuration is not necessarily limited to this. The psychological state guidance system 1 can be used in various moving bodies, for example, it may be configured to be used in railroad vehicles or the like, or may be configured to be used in moving bodies other than vehicles such as aircraft and ships. Further, the configuration is not limited to the configuration used in a mobile body, and may be a configuration used in a room such as a house or facility other than the mobile body. In this case, the target person for guidance of the psychological state in this room corresponds to the target person.
