As shown in FIG. 1, the information presentation system 10 includes an imaging unit 20, a presentation unit 30, and a processing unit 40.

The imaging unit 20 is a device or a system for taking an image including the head of the person H1 who is a target of which information is presented by the information presentation system 10. The imaging unit 20 includes one or more cameras. In the present embodiment, the person H1 is assumed to be a driver who drives the moving body 100. The person H1 is not necessarily limited to the driver, and may be a person sitting in a passenger seat, a rear seat, or the like. As shown in FIG. 2, the image capturing unit 20 is arranged at a position where an image including the head of the person H1, particularly an image of the face of the person H1 can be taken in the main body 101 of the moving body 100. The image captured by the image capturing unit 20 is provided to the processing unit 40.

The presentation unit 30 is a device or a system for presenting information to the person H1. That is, the presentation unit 30 is a human-machine interface. The presentation unit 30 includes an image display device 31, a sound output device 32, and a head-up display 33. The image display device 31 and the head-up display 33 are devices or systems for presenting visual information to the person H1. The image display device 31 may include one or more displays such as a liquid crystal display and an organic EL display. In the present embodiment, the image display device 31 includes a liquid crystal display of a car navigation system mounted on the main body 101. The image display device 31 has a screen 310 as shown in FIG. The voice output device 32 is a device or system for presenting auditory information to the person H1. Audio output device 32 may include one or more speakers. In the present embodiment, the audio output device 32 includes an audio system mounted on the main body 101.

The processing unit 40 is an electric circuit having a role of controlling the operation of the information presentation system 10. The processing unit 40 can be realized by, for example, one or more processors (microprocessors). That is, the one or more processors function as the processing unit 40 by executing the one or more programs stored in the one or more memories. The one or more programs may be pre-recorded in the memory, may be provided through an electric communication line such as the Internet, or may be recorded in a non-transitory recording medium such as a memory card and provided.

As shown in FIG. 1, the processing unit 40 includes a state acquisition unit 41, a motion detection unit 42, and a presentation control unit 43. The state acquisition unit 41, the motion detection unit 42, and the presentation control unit 43 do not show actual configurations, but show the functions realized by the processing unit 40.

The state acquisition unit 41 acquires the state (current state) of the head of the person H1 who is on the moving body 100. The state includes the viewpoint (gazing point) of the person H1 and the position of the head of the person H1. As shown in FIG. 2, the viewpoint is where the line of sight Q1 of the person H1 is focused. In short, the state acquisition unit 41 detects the place where the person H1 is looking inside the moving body 100. In the present embodiment, the state acquisition unit 41 detects the viewpoint of the person H1 based on the image of the head of the person H1 obtained from the imaging unit 20. A conventionally well-known eye tracking technique (particularly, optical tracking) can be used to detect the viewpoint. In addition, the state acquisition unit 41 detects the position of the head of the person H1 inside the moving body 100. In the present embodiment, the state acquisition unit 41 detects the position of the head of the person H1 based on the image of the head of the person H1 obtained from the imaging unit 20. Since the position of the head of the person H1 can be detected by a conventionally known technique, the description thereof will be omitted.

The motion detection unit 42 determines whether or not the person H1 has performed a predetermined motion of looking into the display unit R10 based on the state (state of the head of the person H1) acquired by the state acquisition unit 41. In the present embodiment, the moving body 100 has two display units R10. Therefore, whether the motion detection unit 42 performs the predetermined motion in which the person H1 looks into the display unit R10 based on the state (the state of the head of the person H1) acquired by the state acquisition unit 41 for each display unit R10. Determine whether

More specifically, the motion detection unit 42 determines that the person H1 has performed a predetermined motion when the head of the person H1 approaches the display unit R10 while the person H1 is visually recognizing the display unit R10. .. As a result, it is possible to improve the determination accuracy of the predetermined motion of the person H1.

The motion detection unit 42 determines whether or not the person H1 is visually recognizing the display unit R10 based on the viewpoint of the person H1. The angle θ (see FIG. 3) between the vector of the line of sight Q1 and the reference vector is used to determine whether or not the person H1 is visually recognizing the display portion R10. The vector of the line of sight Q1 can be defined as a vector from the reference point P1 of the head of the person H1 toward the viewpoint of the person H1. The reference point P1 of the head of the person H1 is a reference of the position of the head of the person H1 or a place serving as a starting point of the line of sight of the person H1. For example, the reference point P1 of the head of the person H1 is the midpoint of the left and right eyes of the person H1. The reference vector can be defined as a vector from the reference point P1 of the head of the person H1 toward the predetermined point P2 of the display unit R10. The predetermined point P2 on the display section R10 is a reference point for the position of the display section R10. For example, the predetermined point P2 on the display section R10 is the center point of the display section R10. The calculation of the angle θ can be performed by a conventionally known technique, and thus the description thereof will be omitted.

If the angle θ is equal to or less than the threshold value θth, the motion detection unit 42 determines that the person H1 is visually recognizing the display unit R10. On the other hand, if the angle θ exceeds the threshold value θth, the motion detection unit 42 determines that the person H1 is not visually recognizing the display unit R10. The threshold value θth is 20 [deg] in this embodiment. The threshold value θth can be determined by the size of the display unit R10 and the distance between the reference position of the head of the person H1 and the display unit R10 (predetermined point P2). Here, the reference position of the head of the person H1 may be defined as the position of the head of the person H1 when the person H1 is not looking into the head. For example, the reference position of the head of the person H1 is the position of the head of the person H1 in a state where the person H1 is sitting on the seat of the moving body 100 with his back straight.

The motion detection unit 42 determines whether or not the head of the person H1 approaches the display unit R10 based on the temporal change in the position of the head of the person H1. The distance r (see FIG. 3) between the head of the person H1 and the display unit R10 is used to determine whether or not the head of the person H1 has approached the display unit R10. The distance r between the head of the person H1 and the display section R10 is the distance between the position of the head of the person H1 and the predetermined point P2 of the display section R10. The calculation of the distance r can be performed by a conventionally well-known technique, and thus the description thereof will be omitted.

In the present embodiment, the motion detection unit 42 determines that the head of the person H1 approaches the display unit R10 when the distance r between the head of the person H1 and the display unit R10 decreases for a predetermined time sth. To do. The predetermined time sth is 1000 [msec] in this embodiment. The predetermined time sth may be set as appropriate in consideration of the time required for the person H1 to look into the object.

FIG. 4 shows changes over time in the angle θ and the distance r. In FIG. 4, at time t11, the angle θ becomes equal to or less than the threshold value θth. Therefore, the motion detection unit 42 determines that the person H1 is visually recognizing the display unit R10. Thereby, the motion detection unit 42 determines whether or not the head of the person H1 approaches the display unit R10. The motion detector 42 calculates the distance r and determines whether or not the distance r has decreased. The motion detection unit 42 determines that the head of the person H1 has approached the display unit R10 at time t12 when the duration of the state in which the distance r is decreasing continues for the predetermined time sth. As a result, the motion detection unit 42 determines that the person H1 has performed the predetermined motion. When the angle θ exceeds the threshold value θth after the time t11 in FIG. 4, the duration of the state in which the distance r is decreasing is reset. Further, even when the angle θ is equal to or smaller than the threshold value θth, even when the distance r increases instead of decreasing, the duration of the state in which the distance r is decreasing is reset.

When the motion detection unit 42 determines that the person H1 has performed the predetermined motion, the presentation control unit 43 presents the predetermined information by a presentation method different from that of the display unit R10 (first display unit R11, second display unit R12).

In the present embodiment, the presentation method can be defined by a combination of two elements of a presentation format and a presentation mode.

The presentation format is a format of information that the person H1 can recognize. In other words, the form of presentation defines by what medium the information is conveyed. Examples of the presentation format include visual information (visually recognizable medium), auditory information (audible recognizable medium), and tactile information (tactile recognizable medium). In the present embodiment, the presentation format is selected from visual information and auditory information. In the present embodiment, the image display device 31 and/or the head-up display 33 can be used to present the visual information. On the other hand, the audio output device 32 can be used to present the auditory information.

A presentation aspect defines how to convey information in a medium defined by the format of the presentation. Therefore, the presentation mode differs depending on the presentation format. For visual information, the presentation aspect may include where the information is presented and how the information is arranged. The location of information presentation defines to which location of the mobile unit 100 the information is presented. For example, the location of presenting information indicates whether the information is displayed on the image display device 31 or the head-up display 33. On the other hand, the way of arranging the information relates to the layout of the information to be presented, and includes, for example, the types, sizes (for example, enlargement/reduction of images), colors, etc. of the characters, figures, etc. that make up the information to be presented.

In the present embodiment, "presenting the predetermined information by a presentation method different from that of the display unit" means that the presentation method by the presentation control unit 43 is the presentation method and the presentation method by the display unit R10. It means that at least one of the above aspects is different.

Next, an example of a presentation method in the presentation control unit 43 will be given.

For example, the presentation method of the presentation control unit 43 is a method of visually presenting the predetermined information, and the way of arranging the predetermined information may be different from that of the display unit R10. That is, the presentation method of the presentation control unit 43 differs from the presentation method of the display unit R10 in the presentation mode. For example, FIG. 5 shows an example of predetermined information presented on the screen 310 of the image display device 31 by the first display unit R11. In FIG. 5, the predetermined information displayed on the screen 310 is parking assist information. The parking assist information includes a first image (top view) as if the mobile body 100 was looked down from above and a second image (rear view) behind the mobile body 100. The first image is displayed on the first portion 311 of the screen 310, and the second image is displayed on the second portion 312 of the screen 310. On the other hand, FIG. 6 shows an example of the predetermined information presented on the screen 310 of the image display device 31 by the presentation control unit 43. In FIG. 6, the parking assist information (predetermined information) includes a first image (top view) that looks down on the moving body 100 from above, and a second image (rear view) behind the moving body 100. .. The first image is displayed on the first portion 311 of the screen 310, and the second image is displayed on the second portion 312 of the screen 310. However, the presentation control unit 43 displays the second image on the second portion 312 of the screen 310 in an enlarged manner as compared with the case of the first display unit R11. In other words, the presentation method by the presentation control unit 43 is a method of visually presenting the predetermined information as in the case of the first display unit R11, but a method of arranging the predetermined information by enlarging the second image of the predetermined information. Is different from the first display portion R11. This makes it easier for the person H1 to understand the parking assist information (predetermined information) than the first display portion R11.

For example, the presentation control unit 43 may present the predetermined information in a place different from the display unit R10. For example, the first display unit R11 may display the predetermined information on the screen 310 of the image display device 31, but the presentation control unit 43 may display the predetermined information on the head-up display 33. In this case, the presentation method in the presentation control unit 43 differs from the presentation method in the display unit R10 in the presentation mode (place of information presentation). By changing the location of information presentation as described above, the person H1 can easily understand the parking assist information (predetermined information) than the first display unit R11.

For example, the presentation method of the presentation control unit 43 may be a method of auditorily presenting the predetermined information. That is, the presentation method of the presentation control unit 43 may be different from the presentation method of the display unit R10 in the presentation format. For example, for the first display unit R11, the navigation information (destination, distance to the destination, etc.), the title of music or video being played, and the like may be presented aurally by the audio output device 32. For example, for the second display unit R12, the audio output device 32 may audibly present information about the current state of the mobile body 100. Specifically, the voice output device 32 is used to drive the traveling speed (current speed) of the moving body 100, the remaining amount of gasoline (remaining amount of battery), the traveling distance, the number of revolutions of the engine, the lighting of the warning light, and the indicator light. You may notify the lighting.

1.3 Operation Next, the operation of the information presentation system 10 will be briefly described with reference to the flowchart of FIG. 7. In the information presentation system 10, the imaging unit 20 acquires an image including the head of the person H1 (S11). Next, the state acquisition unit 41 acquires the state (current state) of the head of the person H1 from the image captured by the image capturing unit 20. The state includes the viewpoint (gazing point) of the person H1 and the position of the head of the person H1. The motion detection unit 42 determines whether or not the person H1 has performed a predetermined motion of looking into the display unit R10 based on the state (state of the head of the person H1) acquired by the state acquisition unit 41 (S13). When the motion detection unit 42 determines that the person H1 has performed the predetermined motion (s13: Yes), the presentation control unit 43 presents the predetermined information different from the display unit R10 (the first display unit R11, the second display unit R12). (S14).

1.4 Summary The information presentation system 10 described above includes the state acquisition unit 41, the motion detection unit 42, and the presentation control unit 43. The state acquisition unit 41 acquires the state of the head of the person H1 who is on the moving body 100 having the display unit R10 that visually presents the predetermined information (see FIG. 2 ). The motion detection unit 42 determines whether or not the person H1 has performed a predetermined motion of looking into the display unit R10 based on the state acquired by the state acquisition unit 41. When the motion detection unit 42 determines that the person H1 has performed the predetermined motion, the presentation control unit 43 presents the predetermined information by a presentation method different from that of the display unit R10. According to the information presentation system 10, information can be appropriately presented to the person H1 who is on the moving body 100.

In other words, it can be said that the information presentation system 10 executes the following method (information presentation method). The information presentation method acquires the state of the head of the person H1 who is on the moving body 100 having the display unit R10 that visually presents the predetermined information. The information presentation method determines whether or not the person H1 has performed a predetermined operation of looking into the display unit R10 based on the state. When it is determined that the person has performed the predetermined motion, the information presentation method presents the predetermined information by a presentation method different from that of the display unit R10. According to this information presentation method, information can be properly presented to the person H1 who is on the moving body 100.

The information presentation method is realized by one or more processors executing a program (computer program). This program is a program for causing one or more processors to execute the information presentation method. According to such a program, information can be appropriately presented to the person H1 who is on the moving body 100, as in the information presentation method.

2. Modification Embodiments of the present disclosure are not limited to the above-described embodiments. The above embodiment can be variously modified according to the design and the like as long as the object of the present disclosure can be achieved. The modifications of the above embodiment are listed below.

In a modification, the motion detection unit 42 may determine whether or not the person H1 is visually recognizing the display unit R10 based on the position of the viewpoint instead of the angle θ. For example, the movement detection unit 42 may determine that the person H1 is visually recognizing the display unit R10 when the viewpoint is on the display unit R10. Whether or not the person H1 visually recognizes the display portion R10 can be determined by other conventionally known techniques.

In the above-described embodiment, the motion detection unit 42 determines that the head of the person H1 approaches the display unit R10 when the distance r between the head of the person H1 and the display unit R10 decreases for a predetermined time sth. To do. In a modification, the motion detection unit 42 may determine that the head of the person H1 has approached the display unit R10 when the distance r between the head of the person H1 and the display unit R10 has decreased by a predetermined value rth. The predetermined value rth is 100 [mm] in this embodiment. The predetermined value rth may be set as appropriate in consideration of the distance that changes due to the look-in motion of the person H1. FIG. 8 shows changes over time in the angle θ and the distance r. In FIG. 8, the angle θ becomes equal to or smaller than the threshold value θth at the time point t21. Therefore, the motion detection unit 42 determines that the person H1 is visually recognizing the display unit R10. Thereby, the motion detection unit 42 determines whether or not the head of the person H1 approaches the display unit R10. The motion detection unit 42 calculates the distance r and determines whether the decrease value of the distance r has reached a predetermined value rth. The motion detection unit 42 determines that the head of the person H1 approaches the display unit R10 at time t22 when the decrease value of the distance r reaches the predetermined value rth. As a result, the motion detection unit 42 determines that the person H1 has performed the predetermined motion. When the angle θ exceeds the threshold value θth after time t21 in FIG. 8, the decrease value of the distance r is reset.

In a modification, the presentation control unit 43 may change the presentation method according to the aspect of the predetermined operation. An example of the mode of the predetermined operation is a predetermined operation in which the reference point P1 of the head of the person H1 is different. More specifically, as an example of the predetermined operation in which the reference point P1 of the head of the person H1 is different, an operation of a person sitting in the driver's seat looking into the display unit R10 and a person sitting in the passenger seat are displayed. An operation of looking into the section R10 can be given. If the predetermined operation is an operation in which a person sitting in the driver's seat looks into the display unit R10, the presentation control unit 43 may present the predetermined information by the voice output device 32 or the head-up display 33. On the other hand, if the predetermined action is an action in which the person sitting in the passenger seat looks into the display unit R10, the presentation control unit 43 may present the predetermined information by the image display device 31. The predetermined motion in which the reference point P1 of the head of the person H1 is different includes a predetermined motion in which the height is different in the same seat. In this case, the presentation control unit 43 can change the presentation method according to the height of the reference point P1. For example, when the reference point P1 is high, the presentation control unit 43 may display the display easily from a high position, and when the reference point P1 is low, the display may be easily displayed from a low position.

In a modification, the presentation control unit 43 may change the presentation method according to the attribute of the person H1. The attributes of the person H1 include age and sex. As an example, consider a case where the attribute of the person H1 is age. Here, in the presentation method by the presentation control unit 43, if the display information of the display unit R10 is presented in a visible manner such as characters, the age is less than the predetermined value when the age is the predetermined value or more. Letters and the like may be larger than in the case. As a result, information can be appropriately presented to the person H1 who is on the moving body 100. As the attribute of the person H1, various information other than age and sex (for example, height, sitting height, visual acuity) can be used. The attribute of the person H1 may be determined from the image of the person H1 obtained from the imaging unit 20 or may be acquired from an external system.

In a modification, the display unit R10 may be any part inside the moving body 100, and is not limited to the examples (first display unit R11, second display unit R12) of the above-described embodiment. Examples of the display unit R10 include a control panel of an air conditioner of the moving object 100, an operation panel of a power window, a driver's seat, a passenger seat, a rear seat, and a rearview mirror (room mirror, side mirror). The display unit R10 does not have to be a part of the main body 101 of the moving body 100, and may be a part or the whole of the device inside the moving body 100. For example, the display unit R10 may be the screen of the terminal device in the mobile body 100. The terminal device is a smartphone, a tablet terminal, a wearable terminal, or the like. In this case, the information presentation system 10 may communicate with the terminal device to acquire the predetermined information of the display unit R10. For example, when displaying navigation information on the screen of the terminal device, the terminal device is arranged at a predetermined position in the moving body 100. Therefore, the screen of the terminal device can be detected as the display unit R10.

In a modification, the information presentation system 10 does not have to include the imaging unit 20 and the presentation unit 30 and can be realized as long as the processing unit 40 is included. That is, the image capturing unit 20 and the presenting unit 30 are optional elements for the information presenting system 10, and may be included in the system with which the information presenting system 10 cooperates. In short, the information presentation system 10 may acquire an image of the person H1 from an external system and send control information for presenting the predetermined information to the external system.

In a modification, the moving body 100 on which the information presentation system 10 is mounted may be a vehicle such as a motorcycle, a train, an aircraft, a construction machine, and a ship, instead of a vehicle.
