FIG. 1 is a diagram schematically showing the interior of a vehicle according to this embodiment. The vehicle interior refers to the interior of the vehicle CR. Here, the vehicle CR is mainly assumed to be a vehicle capable of traveling on a road surface (automobile, etc.), but the vehicle CR may be any type of vehicle. The direction from the driver's seat of the vehicle CR to the steering wheel is defined as "forward", and the direction from the steering wheel of the vehicle CR to the driver's seat is defined as "rear". A direction perpendicular to the front-rear direction and parallel to the road surface is defined as a left-right direction.

A maximum of n passengers can board the vehicle CR, and the vehicle CR is provided with seats on which n passengers can sit. In this embodiment, an occupant refers to an occupant riding in the vehicle CR, unless otherwise specified. Although n may be any integer equal to or greater than 2, unless otherwise specified in this embodiment, it is assumed that "n=6", and six seats ST[1] to ST[6] are installed in the vehicle. It is assumed that there is

The seat ST[1] is a driver's seat in which a driver who operates the vehicle CR should sit. It is assumed that the driver faces forward and sits on the seat ST[1], and the seat ST[2] corresponding to the passenger seat is installed on the left side of the seat ST[1]. The left and right sides of the vehicle CR refer to the left and right sides of the driver sitting on the seat ST[1] facing forward. Seats ST[3] to ST[6] are installed behind seat ST[1]. The seats ST[3] and ST[4] are arranged along the left-right direction of the vehicle CR, and the seats ST[5] and ST[6] are also arranged along the left-right direction of the vehicle CR. Seat ST[3] is positioned between seats ST[1] and ST[5], and seat ST[4] is positioned between seats ST[2] and ST[6].

The six passengers on board the vehicle CR are referred to as passengers PS[1] to PS[6]. Passengers PS[1] to PS[6] are seated in seats ST[1] to ST[6], respectively. However, even if "n=6", the number of passengers actually boarding the vehicle CR may be 5 or less. If n is not 6, the number of seats is changed according to the value of n. For example, when "n=4", the seats ST[5] and ST[6] are not present in the vehicle, and in this case, the passengers PS[5] and PS[6] are not present.

As the vehicle CR according to the present embodiment, a passenger car in which a plurality of unspecified passengers board is assumed. Shared vehicles include shared buses and shared taxis, and also include automobiles called rideshare cars.

FIG. 2 shows a configuration diagram of a system SYS, which is a video partition system according to an embodiment of the present invention. The system SYS comprises a processing block 10, a mist generation block 20, a projection block 30, a camera block 40 and an interface block 50. Each component of the system SYS is installed in the vehicle CR.

The processing block 10 includes a control section 11 , a storage section 12 and a communication processing section 13 . The control unit 11 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like, and controls overall operations within the system SYS. The storage unit 12 consists of a magnetic disk, a semiconductor memory, or the like, or a combination thereof, and stores various programs and data. Various functions may be realized by the CPU of the control unit 11 executing the programs in the storage unit 12 . The communication processing unit 13 is wirelessly connected to a predetermined communication network NET, and performs two-way communication with a counterpart device via the communication network NET. The communication network NET includes the Internet, mobile communication networks, and short-range wireless communication networks such as Bluetooth (registered trademark). The partner device is an arbitrary device connected to the communication network NET, and may include, for example, a server device SV connected to the Internet, or a terminal device (not shown) possessed by each passenger. . A terminal device possessed by each passenger is an electronic device such as a smart phone, tablet, or personal computer, and can be connected to a short-range wireless communication network such as Bluetooth (registered trademark).

The mist generation block 20 has a plurality of mist generators 21 . The total number of mist generators 21 provided in the mist generating block 20 depends on the number of seats in the vehicle CR, the arrangement of the seats, and the like. It is also possible to set the total number of mist generators 21 provided in the mist generating block 20 to one. Each mist generator 21 is installed at a proper place in the vehicle compartment. Each mist generator 21 generates mist at the required timing under the control of the controller 11 . Although the details will be described later, the mist forms a mist display.

Projection block 30 comprises a plurality of projectors 31 . Each projector 31 is, for example, a single focus projector. Each projector 31 is associated with any mist display formed by the mist generation block 20 . Each projector 31 projects an image on the corresponding mist display under the control of the control unit 11 to display the image on the corresponding mist display. The image displayed on the mist display may be an image classified as a hologram. The display of images on the mist display is, in detail, the display of images on the screen of the mist display. Each projector 31 is installed at an appropriate place in the vehicle interior so as to be able to project an image. The number of projectors 31 corresponding to the total number of mist generators 21 provided in the mist generation block 20 may be provided. It is also possible to set the total number of projectors 31 provided in the projection block 30 to one.

The camera block 40 has a plurality of cameras 41 . Each camera 41 is installed at an appropriate place inside the vehicle, and has a field of view of a predetermined area inside the vehicle. The field of view (capturing area) differs between any two cameras 41 . Typically, for example, one camera 41 is assigned to each seat. In this case, the camera 41 assigned to the seat ST[i] (the camera 41 associated with the seat ST[i]) captures all or part of the passenger PS[i] in its field of view, and the passenger PS[i] to generate a photographed image representing the result of photographing. Each camera 41 generates a captured image at a predetermined frame rate. Image data representing images captured by each camera are sent to processing block 10 . It is also possible to set the total number of cameras 41 provided in the camera block 40 to one.

The interface block 50 is a man-machine interface between the system SYS and each passenger PS[1]-PS[6]. The processing block 10 may receive predetermined instructions from each passenger PS[1]-PS[6] through the interface block 50. FIG.

Each mist generator 21 generates mist between any two adjacent seats among the seats ST[1] to ST[6]. (p, q) = (1, 2), (p, q) = (3, 4), (p, q) = (5, 6), (p, q) = (1, 3), (p , q)=(3,5), (p,q)=(2,4) and (p,q)=(4,6), the seats ST[p] and ST[q] are Two seats next to each other. Mist consists of fine particles of liquid. The liquid that constitutes the mist is water, and the liquid may contain impurities. However, the liquid that constitutes the mist may be a liquid other than water.

The mist generated between the seats ST[p] and ST[q] forms a partition between the seats ST[p] and ST[q] (p and q are different integers). The partition between the seats ST[p] and ST[q] is, in other words, the partition between the passenger PS[p] sitting in the seat ST[p] and the passenger PS[q] sitting in the seat ST[q]. be. The partition between the seats ST[p] and ST[q] includes the positions of the seat ST[p] and the occupant PS[p] and does not include the positions of the seat ST[q] and the occupant PS[q]. Located on the boundary between the p space and the q-th space that includes the positions of the seat ST[q] and the passenger PS[q] but does not include the positions of the seat ST[p] and the passenger PS[p], and the p-th space Separate the space from the qth space. In the system SYS, the above-mentioned partitioning by mist is used as a mist display, and an image is displayed on the mist display.

Referring to FIG. 3, the mist generator 21 that generates a partition by mist between the seats ST[3] and ST[4] is particularly referred to as mist generator 21CD. FIG. 3 shows the positional relationship between the seats ST[3] and ST[4] and the mist generator 21CD when the seats ST[3] and ST[4] are observed from behind the vehicle CR. . The mist generator 21CD has a lower unit 22L installed on the lower surface of the vehicle interior and an upper unit 22U installed on the upper surface of the vehicle interior. In FIG. 3, a dot hatched rectangle 61 represents a mist display formed by the mist generated by the mist generator 21CD. In the mist generator 21CD, an upper unit 22U is installed just above the lower unit 22L. A mist display 61 is formed by emitting mist from the lower unit 22L toward the upper unit 22U (in this case, the upper unit 22U may have a function of sucking mist). Alternatively, the mist display 61 is formed by emitting mist from the upper unit 22U toward the lower unit 22L (in this case, the lower unit 22L may have the function of sucking the mist).

In addition, since the mist is fine liquid particles, when the mist is touched by a person's hand, it gives a feeling of being caught in a breeze. Even if an occupant touches the mist or passes through the mist, the occupant's body and clothes hardly get wet.

FIG. 4 shows the positional relationship between the seats ST[3] and ST[4] and the mist display 61 when the seats ST[3] and ST[4] are observed from above the vehicle CR. The mist display 61 has screens 61C and 61D. Each of the screens 61C and 61D is a two-dimensional screen that extends in the front-rear direction and the vertical direction.

FIG. 5(a) shows the positional relationship among the seat ST[3], the passenger PS[3] and the screen 61C as viewed from the right side of the seat ST[3]. FIG. 5(b) shows the positional relationship among the seat ST[4], the passenger PS[4] and the screen 61D as viewed from the left side of the seat ST[4].

Of the screens 61C and 61D, the screen 61C is associated with the seat ST[3] and the passenger PS[3], and the screen 61D is associated with the seat ST[4] and the passenger PS[4]. The mist display 61 has thickness in the horizontal direction. The screen 61C corresponds to the right surface of the mist display 61, and the screen 61D corresponds to the left surface of the mist display 61. FIG. Therefore, as shown in FIG. 3 or 4, the screen 61C is positioned between the seat ST[3] and the screen 61D, and the screen 61D is positioned between the seat ST[4] and the screen 61C. Become.

In FIG. 3, projector 31C is projector 31 associated with screen 61C, and projector 31D is projector 31 associated with screen 61D. The projector 31C projects the image VC onto the screen 61C, thereby displaying the image VC on the screen 61C. That is, the screen 61C corresponds to the projection plane of the video VC. The projector 31D projects the image VD onto the screen 61D, thereby displaying the image VD on the screen 61D. That is, the screen 61D corresponds to the projection surface of the video VD.

When the mist display 61 is observed from the seat ST[3], the image VC on the screen 61C becomes visible. Accordingly, the passenger PS[3] can visually recognize the image VC on the screen 61C. When the mist display 61 is observed from the seat ST[4], the image VD on the screen 61D becomes visible. Accordingly, the passenger PS[4] can visually recognize the image VD on the screen 61D. However, the image VD on the screen 61D may be slightly seen through by the occupant PS[3]. Similarly, the image VC on the screen 61C may be slightly seen through by the occupant PS[4].

The screens 61C and 61D may be configured by two mist displays separated from each other. In this case, a first mist generator forming the first mist display and a second mist generator forming the second mist display are arranged between the seats ST[3] and ST[4], and these two first mist generators are arranged between the seats ST[3] and ST[4]. and the second mist generator constitute a mist generator 21CD. At this time, the first mist display is formed between the seat ST[3] and the second mist display, and the second mist display is formed between the seat ST[4] and the first mist display. Among the surfaces of the first mist display, the surface facing the seat ST[3] functions as a screen 61C, while the surface of the second mist display facing the seat ST[4] functions as a screen 61D. It should work.

Also, a configuration may be adopted in which a specific information image (for example, image VC1_1a or VC1_2 described later; see FIGS. 8 and 11) is not displayed on the screen of the mist display. In this configuration, one mist display may be formed commonly for the two adjacent seats instead of forming separate mist displays for each of the two adjacent seats. The one mist display functions as a mere partition, and can reduce the required number of mist generators compared to the case where the first and second mist generators are provided.

In any mist generator 21, the period during which mist is generated is called a mist generation period (partition generation period due to mist), and the period during which mist is not generated is called a mist non-generation period (partition non-generation period due to mist). period). A mist display 61 is formed during the mist generation period of the mist generator 21CD. The mist display 61 is not formed during the mist non-generating period in the mist generator 21CD. Regarding the mist generator 21CD, during the mist generation period, the mist display 61 is present compared to the mist non-generation period. An effect of making it difficult to see the passenger PS[3] (hereinafter referred to as a blind effect) is obtained. The mist display 61 is large enough to provide an appropriate blind effect. By displaying an image on the mist display 61, the blind effect is strengthened.

The control unit 11 individually controls operation or non-operation of the plurality of mist generators 21 included in the mist generation block 20 . When a certain mist generator 21 operates, mist is generated from the mist generator 21 . When a mist generator 21 is inactive, no mist is generated from that mist generator 21 . In addition, the control unit 11 individually controls activation or deactivation of the plurality of projectors 31 included in the projection block 30 . When a certain projector 31 operates, an image is projected from the projector 31 to the corresponding mist display. When a certain projector 31 is inactive, no image is projected from that projector 31 . The control unit 11 supplies a video signal to a certain projector 31 when the projector 31 is operating. The projector 31 projects an image corresponding to the supplied image signal onto the corresponding mist display.

Hereinafter, for any mist generator 21, the state in which the mist generator 21 is operating may be referred to as the operating state, and the state in which the mist generator 21 is not operating may be referred to as the non-operating state. . Similarly, for any given projector 31, a state in which the projector 31 is operating may be referred to as an operating state, and a state in which the projector 31 is not operating may be referred to as a non-operating state.

Among the plurality of mist generators 21, the function of the control section 11 will be described by focusing on the mist generator 21CD. The controller 11 controls the mist generator 21CD so that the mist generator 21CD operates to generate mist. During the mist generation period of the mist generator 21CD, the control unit 11 controls the projectors 31C and 31D so that the projectors 31C and 31D operate, supplies a video signal representing the video VC to the projector 31C, and transmits the video to the projector 31D. A video signal representing VD is provided. As a result, the image VC is displayed on the screen 61C of the mist display 61, and the image VD is displayed on the screen 61D of the mist display 61. FIG.

However, it is not essential to always display the image during the mist generation period by the mist generator 21CD. That is, the control unit 11 causes the mist display 61 to display an image (more specifically, an image VC to be displayed on the screen 61C) using the projector 31C during all or part of the mist generation period of the mist generator 21CD. can be done. Similarly, the control unit 11 displays an image on the mist display 61 using the projector 31D (more specifically, displays an image VD on the screen 61D) during the whole or part of the mist generation period by the mist generator 21CD. be able to.

In FIG. 3, the code "41C" represents the camera 41 assigned to the seat ST[3] (the camera 41 associated with the seat ST[3]), and the code "41D" is assigned to the seat ST[4]. represents the camera 41 (the camera 41 associated with the seat ST[4]). For example, the camera 41C is installed directly above the seat ST[3] and on the upper surface of the passenger compartment, while the camera 41D is installed directly above the seat ST[4] and on the upper surface of the passenger compartment. . The camera 41C captures the whole or part of the occupant PS[3] in its field of view, and generates a photographed image representing the photographed result of the occupant PS[3]. The camera 41D captures the whole or part of the occupant PS[4] in its field of view and generates a photographed image representing the photographed result of the occupant PS[4].

Focusing on seats ST[3] and ST[4] as an example of a combination of two seats adjacent to each other, the structure of the mist display (61) and the like have been described. The same is true for That is, as with the seats ST[3] and ST[4], for any two seats of other combinations, mist is generated between the two seats using the corresponding mist generators 21 to display the mist. can be formed, and images can be displayed on the screen of the mist display using the corresponding projector 31 .

As can be understood from the above description, the control unit 11 can control for each mist generator 21 whether or not the mist generator 21 generates mist. At this time, the control unit 11 continuously monitors and judges whether or not a predetermined mist generation condition is established, and when the mist generation condition is established, the corresponding mist generator 21 is operated to form a mist display. Whether or not the mist generation condition is met can be determined for each occupant of the vehicle CR.

FIG. 6 shows an operation flowchart of the system SYS focusing on the passenger PS[i]. The occupant PS[i] of interest is hereinafter referred to as the occupant of interest PS[i]. A passenger in a vehicle CR, which is a passenger car, is assumed as the passenger of interest PS[i]. Therefore, the occupant of interest PS[i] is any of the occupants PS[2] to PS[6] excluding the driver (that is, the occupant PS[1]). However, when the vehicle CR is fully automatically driven, the passenger PS[1] can also be the passenger of interest PS[i] as one of the passengers. The process of FIG. 6 may be performed for each passenger.

In the flowchart of FIG. 6, first, in step S1, a certain person enters the vehicle CR from the outside of the vehicle CR, thereby starting to get into the vehicle CR as a passenger of interest PS[i]. A passenger of interest PS[i] sits on a seat ST[i]. In step S2 following step S1, the control unit 11 determines whether or not a predetermined mist generation condition is satisfied for the passenger of interest PS[i]. A method for judging whether or not the mist generation condition is satisfied will be described later. If the mist generation condition is established for the passenger of interest PS[i] (Y in step S2), the process proceeds from step S2 to step S3. If the mist generation condition is not established (N in step S2). The determination process of step S2 is repeated.

In step S3, the control unit 11 forms a mist display by causing the mist generator 21 corresponding to the passenger of interest PS[i] to generate mist (that is, by activating the mist generator 21), and further, By projecting an image from the corresponding projector 31 onto the mist display, display of the image on the mist display is started. The mist display described in the explanation of the flowchart in FIG. 6 is a mist display that can be visually recognized by the passenger PS[i] of interest. 3 mist display 61.

Therefore, if the occupant of interest PS[i] is occupant PS[3] or PS[4], the mist generator 21 corresponding to the occupant of interest PS[i] is the mist generator 21CD in FIG. Therefore, if the occupant PS[i] of interest is the occupant PS[3] or PS[4], the projectors 31C and 31D start projecting the images VC and VD onto the mist display 61 in step S3. Display of the image VC on the screen 61C and display of the image VD on the screen 61D are started.

Before reaching step S3, the mist generator 21 for the occupant of interest PS[i] is in a non-operating state, so the mist display is not formed. After step S3, the process proceeds to step S4.

In step S4, the control unit 11 determines whether or not a predetermined mist end condition is satisfied for the passenger of interest PS[i]. A method for judging whether or not the mist end condition is satisfied will be described later. If the mist end condition is established for the passenger of interest PS[i] (Y in step S4), the process proceeds from step S4 to step S5. If the mist end condition is not established (N in step S4). The determination process of step S4 is repeated. Once the mist start condition is met, the mist display continues until the mist end condition is met.

In step S5, the control unit 11 stops the mist generator 21 corresponding to the passenger of interest PS[i] from generating mist (that is, switches the state of the mist generator 21 from the operating state to the non-operating state). As a result, the mist display corresponding to the occupant of interest PS[i] disappears, and therefore the image display on the mist display is also stopped. In step S5, the control unit 11 also stops the operation of the corresponding projector 31 (that is, switches the state of the projector 31 from the operating state to the non-operating state). After step S5, the process proceeds to step S6.

In step S6, if the occupant of interest PS[i] has gotten off the vehicle CR (Y in step S6), the operation of FIG. 6 ends. If the occupant of interest PS[i] is still in the vehicle CR, the process returns to step S2. At this time, the control unit 11 may determine whether or not the occupant of interest PS[i] has gotten off the vehicle CR. For example, the control unit 11 can determine whether or not the passenger of interest PS[i] has gotten off the vehicle CR based on the captured image of the camera 41 that captures the passenger of interest PS[i].

In a passenger car in which an unspecified person rides, each passenger may be concerned about others' eyes and find it difficult to spend their time freely. As described above, by adopting a configuration that generates a partition by mist when a predetermined condition (mist generation condition) is established, space between people is separated only at the necessary timing without physically creating a wall. becomes possible. As a result, private space is protected and it becomes easier to spend time without worrying about other people's eyes (comfort is improved). Alternatively, it is possible to use mist to notify a specific passenger of necessary information (for example, to notify information related to getting off the train), which increases convenience.

If a partition made of mist is used as a mist display, the above-mentioned blind effect is enhanced, and it becomes possible to provide each passenger with a useful image according to the situation of each passenger. Since the mist display does not constitute a physical wall, it does not get in the way when getting in or out of the vehicle, and is highly safe.

Hereinafter, some specific operation examples, applied techniques, modified techniques, etc. in the system SYS will be described among a plurality of embodiments. The matters described above in the present embodiment are applied to each of the following examples unless otherwise stated and without contradiction. In each embodiment, if there are matters that contradict the above-described matters, the description in each embodiment may take precedence. In addition, as long as there is no contradiction, the matter described in any of the following embodiments can be applied to any other embodiment (i.e. any two or more of the embodiments). It is also possible to combine the examples of .

<<First embodiment>>
A first embodiment will be described. In the first embodiment, it is assumed that the occupant PS[i] of interest is the occupant PS[3]. FIG. 7 is an operation flowchart of the system SYS according to the first embodiment under this assumption. The operation of the system SYS according to the first embodiment will be described along the flowchart of FIG.

First, in step S11, a certain person enters the vehicle CR from the outside of the vehicle CR to start boarding the vehicle CR as a passenger PS[3]. Passenger PS[3] sits on seat ST[3]. Image data representing an image of occupant PS[3] captured by camera 41C (hereinafter referred to as captured image data of camera 41C) is sent to control unit 11 . The captured image data of the camera 41C includes image data of a still image and a moving image of the occupant PS[3]. While the passenger PS[3] is in the vehicle CR, the control unit 11 continuously analyzes and detects the type of behavior of the passenger PS[3] based on the image data captured by the camera 41C.

In step S12 following step S11, the control unit 11 determines whether the current behavior of the passenger PS[3] matches a specific type of behavior. If it is determined that the action of the passenger PS[3] matches the specific type of action (that is, if the specific type of action by the passenger PS[3] is detected; Y in step S12), steps from step S12 are performed. The process proceeds to S13, but if not (N in step S12), the determination process of step S12 is repeated. In the first embodiment, the fact that the action of the passenger PS[3] matches the specific type of action (detection of the specific type of action by the passenger PS[3]) corresponds to the establishment of the mist generation condition ( (see step S2 in FIG. 6).

In step S13, the control unit 11 causes the mist generator 21CD corresponding to the passenger PS[3] to generate mist (that is, by activating the mist generator 21CD) to form the mist display 61, and furthermore, By projecting images from the projectors 31C and 31D onto the mist display 61, the image display on the mist display 61 is started. The display of the image on the mist display 61 includes the display of the image VC on the screen 61C of the mist display 61 and the display of the image VD on the screen 61D of the mist display 61. FIG. Examples of displayed images will be described later. Before step S13 is reached, the mist generator 21CD is in a non-operating state, so the mist display 61 is not formed.

After the formation of the mist display 61 and the display of the images VC and VD are started in step S13, the operating state of the mist generator 21CD continues (thus, the mist display 61 continues) and The display of images VC and VD continues. After step S13, the process proceeds to step S14.

After starting the operation of the mist generator 21CD in step S13, the control unit 11 checks whether the action taken by the passenger PS[3] continues to match the specific type of action based on the image data captured by the camera 41C. Monitor continuously. Based on this monitoring result, in step S14, the control unit 11 determines whether or not the specific type of action by the passenger PS[3] has ended. If it is determined that the specific type of action by passenger PS[3] has ended (Y in step S14), the process proceeds from step S14 to step S15; otherwise (N in step S14), determination in step S14. The process is repeated. In the first embodiment, completion of the specific type of action by the passenger PS[3] (determining that the specific type of action by the passenger PS[3] is finished) corresponds to satisfaction of the mist end condition. (See step S4 in FIG. 6).

In step S15, the controller 11 stops the mist generator 21CD from generating mist (that is, switches the state of the mist generator 21CD from the operating state to the non-operating state). As a result, the mist display 61 disappears, and therefore the display of images (display of the images VC and VD) on the mist display 61 is also stopped. In step S15, the control unit 11 also stops the operation of the projectors 31C and 31D (that is, switches the state of the projectors 31C and 31D from the operating state to the non-operating state). After step S15, the process returns to step S12, and the above operation is repeated until the passenger PS[3] gets off the vehicle CR.

The specific type of behavior is a behavior that the crew member PS[3] himself does not like being seen by other crew members from the viewpoint of protecting the privacy of the crew member PS[3].

For example, a particular type of activity may include eating (ie, the act of eating). To create a partition with mist during meals in consideration of feelings of not wanting other people to see eating in a shared car shared by unspecified persons.

The control unit 11 determines whether or not the crew member PS[3] is eating based on the presence or absence of food in the image captured by the camera 41C and the movement of the mouth of the crew member PS[3] in the image captured by the camera 41C. It can be estimated (determined) whether the person is going to eat.

A period in which mist is generated by mist generator 21CD in response to passenger PS[3] having a meal is hereinafter particularly referred to as a meal-response mist generation period. A period in which the crew member PS[3] has not yet started eating but is estimated to start eating soon may also be included in the meal-response mist generation period. During the meal-related mist generation period, the control unit 11 supplies a video signal to the projector 31C so that a meal-related image (image related to the behavior of the passenger PS[3]) is displayed on the screen 61C as the image VC. The display of the meal-related image on the screen 61C may be carried out only during part of the meal-related mist generation period.

FIG. 8 shows a video VC_1a, which is an example of a video related to meals. In the example of FIG. 8, the video VC_1a is displayed on the screen 61C. The meal-related video as the video VC is, for example, a video showing the nutritional balance of the food eaten by the crew member PS[3] or the food presumed to be eaten by the crew member PS[3] during the meal-related mist generation period. be. The food held by the passenger PS[3] corresponds to the food presumed to be eaten by the passenger PS[3]. It is preferable that the control unit 11 be capable of object detection processing for identifying the type of food in the image based on the image data of the image containing food as an object. The control unit 11 may include a DNN (deep neural network) for realizing object detection processing.

Alternatively, for example, the video related to meals as the video VC may be a video of restaurant information. The restaurant information may be information about nearby restaurants when viewed from the current position of the vehicle CR, or may be information about nearby restaurants when viewed from the scheduled alighting point of the passenger PS[3]. The restaurant information is information on restaurants that provide the same or similar type of food as the food that the crew member PS[3] ate or the food that the crew member PS [3] is estimated to eat during the meal-related mist occurrence period. can be

In addition, during the meal-related mist generation period, any image related to meals (recently popular food introduction image, etc.) can be displayed on the screen 61C of the mist display 61 as the image VC.

A particular type of activity may include sleeping (ie, the act of sleeping). To create a partition with mist during sleep, taking into consideration the feeling of not wanting others to see sleeping in a passenger car shared by unspecified persons.

Based on the facial image of the passenger PS[3] in the captured image of the camera 41C (especially, based on the image of the eyes of the passenger PS[3], for example), the control unit 11 determines whether the passenger PS[3] is asleep. It can estimate (determine) whether the person is sleeping or is trying to sleep.

A period during which mist is generated by the mist generator 21CD in response to the occupant PS[3] sleeping is hereinafter particularly referred to as a sleep mist generation period. A period in which the passenger PS[3] has not started sleeping yet but is estimated to start sleeping soon may also be included in the sleep mist generation period. During the mist generation period for sleep, the control unit 11 supplies a video signal to the projector 31C so that an image related to sleep (image related to the behavior of the passenger PS[3]) is displayed on the screen 61C as the image VC. The display of sleep-related images on the screen 61C may be performed only during a part of the sleep-related mist generation period.

FIG. 9 shows a video VC_1b, which is an example of a video related to sleep. In the example of FIG. 9, video VC_1b is displayed on screen 61C. The sleep-related video as the video VC may be, for example, a predetermined healing video that is expected to contribute to improving the quality of sleep. The sleep-related video as the video VC may be a video that matches the preference of the passenger PS[3]. For example, the control unit 11 establishes pairing with a terminal device (such as a smart phone; not shown) possessed by the crew member PS[3], and establishes the operation history of the terminal device (website browsing) by the crew member PS [3]. The preference of the passenger PS[3] can be estimated based on the history) and the like.

The specific type of action may be other than eating and sleeping, and for example, the specific type of action may include the action of relaxing (relaxing action) of the passenger PS[3]. At this time, based on the captured image data of the camera 41C, when it is detected that the crew member PS[3] yawns or stretches his arms upward, the crew member PS[3] is relaxed, and a transition from step S12 to step S13 may occur.

During the period in which the mist is generated by the mist generator 21CD and the mist display 61 is formed in response to the occupant PS[3] taking a specific type of action (for example, during the mist generation period for meals or during the mist generation period for sleep). , the control unit 11 may display a predetermined reference image as the image VD on the screen 61D. Any image may be used as the reference image, but it is preferable that it is an image that makes it difficult for passengers PS[4] to PS[3] and the image VC displayed on the screen 61C to be seen. For example, an image in which light appears to flicker can be used as the reference image.

In the first embodiment, as described above, it is determined whether or not the predetermined condition (mist generation condition) is met based on the image captured by the camera 41C that captures the occupant PS[3]. A partition is generated by mist. By referring to the image captured by the camera 41C, it can be estimated well whether or not it is better to create a partition with mist from the viewpoint of privacy protection or the like.

Specifically, when it is determined that the behavior of the occupant PS[3] matches a specific type of behavior based on the image captured by the camera 41C, a partition is created using mist. As a result, it is possible to hide the appearance of the passenger PS[3] taking a specific type of action (particularly, for example, eating or sleeping) from others without physically creating a wall, thereby protecting the privacy of the passenger PS[3]. Connect.

At this time, a partition made of mist is used as a mist display 61, and an image related to the behavior of the passenger PS[3] is displayed on the mist display 61. FIG. This makes it possible not only to generate a partition but also to provide the passenger PS[3] with an image that matches the behavior of the passenger PS[3] using the partition. This contributes to improving the degree of satisfaction of the passenger PS[3] during his stay in the vehicle.

<<Second embodiment>>
A second embodiment will be described. Also in the second embodiment, it is assumed that the occupant PS[i] of interest is the occupant PS[3]. FIG. 10 is an operation flowchart of the system SYS according to the second embodiment under this assumption. The operation of the system SYS according to the second embodiment will be described along the flowchart of FIG.

It should be noted that the arbitrary times described in the second embodiment are all times within the same day (for example, times during May 11, 2021 AD). Also, the person who should be the passenger PS[3] uses a terminal device (such as a smart phone; not shown) to transmit his/her scheduled alighting point to the server device SV before getting on the vehicle CR. The server device SV constitutes a reservation system that accepts requests and plans for each person's movement using the vehicle CR. The scheduled alighting point described in the present embodiment is the scheduled alighting point of the passenger PS[3] and the point at which the passenger PS[3] is scheduled to get off the vehicle CR.

First, in step S21, a certain person enters the vehicle CR from the outside of the vehicle CR to start boarding the vehicle CR as a passenger PS[3]. Passenger PS[3] sits on seat ST[3]. It is assumed that the information indicating the scheduled alighting point of the passenger PS[3] is transmitted from the server device SV to the control unit 11 before reaching step S21. After step S21, the process proceeds to step S22.

The control unit 11 recognizes the current location of the vehicle CR from a GPS processing unit (not shown) provided in the vehicle CR. The GPS processing unit may be included in processing block 10 . The GPS processing unit detects the current position of the vehicle CR by receiving signals from a plurality of GPS satellites forming a GPS (Global Positioning System). Further, the control unit 11 derives the scheduled arrival time of the vehicle CR at the scheduled alighting point of the occupant PS[3] based on the current location of the vehicle CR, the scheduled alighting point of the occupant PS[3], and the current time. The scheduled time at which the vehicle CR arrives at the planned alighting point of the passenger PS[3] coincides with the scheduled alighting time of the passenger PS[3]. The scheduled arrival time of the vehicle CR at the scheduled alighting point of the passenger PS[3] may be determined in advance according to a predetermined operation schedule.

At an arbitrary timing before the vehicle CR arrives at the scheduled alighting point of the passenger PS[3], the control unit 11 controls the remaining time until the scheduled alighting time of the passenger PS[3] (hereinafter referred to as remaining time _tR ). can be derived. The remaining time _tR is the time from the current time to the scheduled time when the passenger PS[3] gets off. Further, the control unit 11 controls the remaining distance (hereinafter , called the remaining distance d _R ) can be derived. The remaining distance dR represents the distance that the vehicle _CR should travel from the current location of the vehicle CR to the scheduled alighting location of the passenger PS[3].

In step S22, the control unit 11 performs time determination processing to determine whether or not the remaining time _tR until the passenger PS[3]'s scheduled alighting time is equal to or less than a predetermined time _tTH . In step S22, in addition to the time determination process or instead of the time determination process, the control unit 11 determines whether or not the remaining distance _{dR to the scheduled alighting point of the passenger PS[3] is equal to or less than a predetermined distance dTH .} You may perform the distance judgment process which judges.

When the time determination process is executed in step S22, if the remaining time _tR is equal to or less than the predetermined time _tTH (Y in step S22), the process proceeds from step S22 to step S23; N) At step S22, the time determination process is repeated. When the distance determination process is executed in step S22, if the remaining distance _{dR is equal to or less than the predetermined distance dTH (} Y in step S22), the process proceeds from step S22 to step S23. N) The distance determination process is repeated in step S22. In the second embodiment, the fact that the remaining time _tR is equal to or less than the predetermined time _tTH or the remaining distance _{dR is equal to or less than the predetermined distance dTH corresponds} to the establishment of the mist generation condition (see step S2 in FIG. 6). ).

In step S23, the control unit 11 causes the mist generator 21CD corresponding to the passenger PS[3] to generate mist (that is, by activating the mist generator 21CD) to form the mist display 61, and furthermore, By projecting images from the projectors 31C and 31D onto the mist display 61, the image display on the mist display 61 is started. The display of the image on the mist display 61 includes the display of the image VC on the screen 61C of the mist display 61 and the display of the image VD on the screen 61D of the mist display 61. FIG. Examples of displayed images will be described later.

After the formation of the mist display 61 and the display of the images VC and VD are started in step S23, the operating state of the mist generator 21CD continues (thus, the mist display 61 continues) and The display of images VC and VD continues. After step S23, the process proceeds to step S24.

After starting the operation of the mist generator 21CD in step S23, the control unit 11 continuously monitors whether or not the passenger PS[3] has gotten out of the vehicle CR based on the image data captured by the camera 41C. In step S24, the control unit 11 determines whether or not the passenger PS[3] has gotten off the vehicle CR. If it is determined that the occupant PS[3] has gotten off the vehicle CR (Y in step S24), the process proceeds from step S24 to step S25. Repeated.

When the vehicle CR stops at the scheduled alighting point of the passenger PS[3] and the door (not shown) separating the interior and exterior of the vehicle CR is open, the passenger PS[3] is seated in the seat ST[3]. When it is detected based on the captured image data of the camera 41C that the passenger PS[3] has left the vehicle CR, the control unit 11 may determine that the passenger PS[3] has gotten off the vehicle CR. Regardless of the image data captured by the camera 41C, when the vehicle CR arrives at the scheduled alighting point of the passenger PS[3], or when the vehicle CR stops at the scheduled alighting point of the passenger PS[3]. , a transition from step S24 to step S25 may be generated. In the second embodiment, it is determined that the occupant PS[3] has gotten off the vehicle CR at the scheduled alighting point of the occupant PS[3], the vehicle CR arrives at the scheduled alighting point of the occupant PS[3], Alternatively, the fact that the vehicle CR stops at the scheduled alighting point of the passenger PS[3] corresponds to the establishment of the mist end condition (see step S4 in FIG. 6).

In step S25, the controller 11 stops the mist generator 21CD from generating mist (that is, switches the state of the mist generator 21CD from the operating state to the non-operating state). As a result, the mist display 61 disappears, and therefore the display of images (display of the images VC and VD) on the mist display 61 is also stopped. In step S25, the control unit 11 also stops the operation of the projectors 31C and 31D (that is, switches the state of the projectors 31C and 31D from the operating state to the non-operating state). After the process of step S25, the operation of FIG. 10 focusing on the occupant PS[3] ends.

A period during which mist is generated by the mist generator 21CD by proceeding to step S23 is hereinafter particularly referred to as a mist generation period for getting off. During the mist occurrence period for getting off, the control unit 11 supplies a video signal to the projector 31C so that the video related to the schedule of the passenger PS[3] is displayed on the screen 61C as the video VC. The display of the image related to the passenger PS[3]'s schedule on the screen 61C may be carried out only during a part of the get-off mist generation period.

FIG. 11 shows a video VC_2, which is an example of a video related to the schedule of the passenger PS[3]. In the example of FIG. 11, the video VC_2 is displayed on the screen 61C. The video VC_2 may include the first notification information based on the time difference between the expected time of getting off of the passenger PS[3] and the current time. The first notification information preferably includes a first message indicating that the vehicle CR will soon arrive at the point where the passenger PS[3] is scheduled to get off, and a second message indicating that preparations to get off are urged. The first message may be a message specifying the remaining time _tR (eg, "Get off in 5 minutes"). The first message may be a message that does not specifically indicate the remaining time _tR (for example, "You will soon arrive at the scheduled drop-off point"). In any case, the first message is information based on the time difference (the expression "soon" is an expression corresponding to the time difference being equal to or less than a predetermined value). In addition to the first notification information, or instead of the first notification information, the video VC_2 may include second notification information related to the scheduled alighting point of the passenger PS[3]. The second notification information includes, for example, the current weather (including the temperature) and weather forecast at the scheduled get-off point. In addition, the second notification information may include transfer guidance at the scheduled alighting point (guidance on use of transportation from the scheduled alighting point).

When the image VC_2 is displayed on the screen 61C, the control unit 11 notifies the passenger PS[3] of the information (for example, the first and second messages) indicated by the image VC_2 in addition to the display. You can do it. The voice notification may be output from a speaker (not shown) installed in the vehicle CR, or may be output from a terminal device (such as a smart phone; not shown) possessed by the passenger PS[3].

During the mist generation period for passenger PS[3], the control unit 11 may cause the screen 61D to display a predetermined reference image as the image VD.

As described above, in the second embodiment, it is determined whether mist is to be generated according to the remaining time _tR to the scheduled alighting time of the passenger PS[3] or the remaining distance _dR to the scheduled alighting point of the passenger PS[3]. judge and control; As a result, it is possible to generate a mist when getting off is approaching, and it is possible to notify the passenger PS[3] that getting off is approaching. As a result, it is possible to prevent the passenger PS[3] from rushing to prepare to get off after arriving at the planned point of getting off, and to prevent forgetting to get off.

Specifically, it is preferable to use a partition made of mist as the mist display 61 and display the image (VC_2) related to the schedule of the passenger PS[3] on the mist display 61 . This makes it possible to use the mist display 61 to inform the passenger PS[3] that getting off is approaching. As a result, it is possible to prevent the passenger PS[3] from rushing to prepare to get off after arriving at the planned point of getting off, and to prevent forgetting to get off.

At this time, if the above-described first notification information or second notification information is included in the video (VC_2) related to the schedule of the passenger PS[3], schedule adjustment of the passenger PS[3] after getting off the vehicle CR can be performed. is supported and convenient.

Incidentally, before step S23 is reached, the mist generator 21CD is in a non-operating state, so the mist display 61 is not formed. However, it is also possible to combine the first and second embodiments. In the case of combining the first and second embodiments, the action of the passenger PS[3] matches the specific type of action before step S23. If it is determined that this is the case (Y in step S12 in FIG. 7), the mist display 61 is formed and an image related to the behavior of the passenger PS[3] (for example, FIG. 8 VC_1a) is displayed on the screen 61C. When the remaining time _tR becomes equal to or less than the predetermined time _tTH or the remaining distance _dR reaches the predetermined distance _dTH while the screen 61C is displaying an image related to the behavior of the passenger PS[3]. In the case below, it is preferable that a transition to step S23 occurs and an image (for example, image VC_2 in FIG. 11) related to the schedule of the passenger PS[3] is displayed on the screen 61C.

<<Third embodiment>>
A third embodiment will be described. Each of the seats ST[1] to ST[6] may be provided with an operation member (not shown) for receiving a predetermined operation from the passenger. This operating member is included in the components of the interface block 50 in FIG. Passenger PS[i] can instruct formation or non-formation of the mist display corresponding to seat ST[i] by operating an operation member provided in seat ST[i]. Activation or deactivation of each mist generator 21 may be controlled based on the instructions.

For example, the occupant PS[3] can instruct the formation or non-formation of the mist display 61 by operating the operation member provided on the seat ST[3], and the control unit 11 generates mist based on the instruction. Activation or deactivation of device 21CD may be controlled.

At this time, the instruction based on the operation of the operation member of the seat ST[3] may be given priority over the actions shown in FIG. 7 or FIG. Therefore, for example, when a predetermined first operation is input to the operation member of the seat ST[3], the control unit 11 controls whether or not the conditions for steps S12 to S13 in FIG. 10, the mist generator 21CD is operated to form the mist display 61, regardless of whether the conditions for reaching from step S22 to step S23 in FIG. The content of the image displayed on the mist display 61 (the content of the image on the screen 61C) may also be determined based on the input operation to the operation member of the seat ST[3]. Further, for example, when a predetermined second operation is input to the operation member of the seat ST[3] while the mist generator 21CD is in operation, the controller 11 moves from step S14 to step S15 in FIG. The mist generator 21CD is switched to the non-operating state regardless of the success or failure of the conditions for reaching step S24 to step S25 in FIG.

The system SYS automatically forms the mist display that is presumed to be necessary by the method of the first or second embodiment, but apart from this, each individual can freely decide whether to form the mist display or not. It is very convenient because it can be done.

In addition, based on the captured image of the camera 41 that includes the seat ST[3] and the occupant PS[3] on the seat ST[3], the controller 11 determines that the occupant PS[3] is seated on the seat ST[3]. It is good to judge whether or not Then, when the control unit 11 detects that the passenger PS[3] is not sitting on the seat ST[3] and is sitting on the seat ST[3], mist is generated for the passenger PS[3]. The mist display 61 may be formed by activating the mist generator 21CD upon judging that the conditions are met.

<<Fourth Embodiment>>
A fourth embodiment will be described. A plurality of mist displays corresponding to a certain passenger may be formed when the mist generation condition is satisfied for the passenger.

That is, for example, when the mist generation condition is established for the passenger PS[3], the first to Jth mist generators 21 corresponding to the passenger PS[3] are operated to form the first to Jth mist displays and project them. The block 30 may be used to display an image on each of the 1st to Jth mist displays. Here, J represents an integer of 2 or more.

The first to Jth mist generators 21 corresponding to the occupant PS[3] may be the first to third mist generators 21 (ie, "J=3"). In this case the first mist generator 21 is the mist generator 21 CD and the first mist display is the mist display 61 . The second mist display is a mist display formed between seats ST[1] and PS[3], and the third mist display is formed between seats ST[3] and PS[5]. It is a mist display. By the first to third mist displays, between seats ST[3] and ST[4], between seats ST[3] and ST[1], and between seats ST[3] and ST[5], , a partition is formed by the mist. The projection block 30 projects an image on each screen of the first to third mist displays under the control of the control section 11 .

<<Fifth embodiment>>
A fifth embodiment will be described. In the fifth embodiment, some supplementary items, applied techniques, modified techniques, etc. for the above items will be described.

Examples of images displayed on the mist display 61 have been described in the first and second embodiments, but examples of images (VC, VD) displayed on the mist display 61 can be modified in various ways. In particular, in the first embodiment, the image displayed on the mist display 61 may be arbitrary, and the image VC displayed on the screen 61C of the mist display 61 during the meal-related mist generation period and sleep-related mist utterance period is As with the video VD, it may be a predetermined reference video. Even if the video VC is not related to the behavior of the passenger PS[3], the privacy can be protected by the blind function.

Focusing on occupant PS[3], examples of the generation timing of mist display 61 between seats ST[3] and ST[4] and the image displayed on mist display 61 have been described above. Each passenger may be similar to passenger PS[3].

All the components of the system SYS may be installed in the vehicle CR, but some of the components of the system SYS may be installed outside the vehicle CR. For example, the processing block 10 may be provided outside the vehicle CR. In this case, the control unit 11 provided outside the vehicle CR communicates with each of the blocks 20 to 50 through the communication processing unit 13. Thus, control of each mist generator 21 and each projector 31 and acquisition of image data from each camera 41 can be realized, and input operation contents to the interface block 50 can be recognized.

The invention can be applied to any kind of vehicle. A vehicle CR as a passenger car is an example of a vehicle. A vehicle according to the invention may be, for example, an aircraft, a ship, a train or a train.

The system SYS of FIG. 2 includes a partition device used in vehicles. A partition device is understood to be a device comprising all or part of the blocks 10 to 50 as components. A partition device includes at least one mist generator 21 and a control unit 11 . Looking between the seats ST[3] and ST[4], the partition device includes a mist generator 21CD and a controller 11 .

The partition device can be configured by hardware such as an integrated circuit, or by a combination of hardware and software. Any specific function that is all or part of the functions realized by the partition device may be written as a program, and the program may be stored in a memory that can be mounted on the partition device. The specific function may be realized by executing the program on a program execution device (for example, a microcomputer that can be installed in the partition device, such as the CPU of the control unit 11). The program can be stored in any recording medium. A recording medium for storing the above program may be mounted on or connected to a device different from the partition device.

The embodiments of the present invention can be appropriately modified in various ways within the scope of the technical idea indicated in the scope of claims. The above embodiments are merely examples of the embodiments of the present invention, and the meanings of the terms of the present invention and each constituent element are not limited to those described in the above embodiments.
