  The best mode for carrying out the present invention will be described below with reference to the drawings. The following embodiment is an example to which the image display system of the present invention is applied, and it goes without saying that the content of the invention is not limited to this embodiment.

[1. First Embodiment]
[1.1 System appearance]
The entire image display system 1 in the first embodiment will be described with reference to FIG. As shown in FIG. 1, the image display system 1 includes a recognition device 20 that recognizes a user P and an image display device 30 that displays an image, and these are a control device 10 (image display control device). It is connected to the.

  In the present embodiment, as an example of the image display device 30, an image display device 32 and an image display device 34 are provided. As the image display device, for example, a display using liquid crystal or the like may be used, or an image may be projected by a projector or the like.

  Here, in this specification, displaying an image includes not only displaying an image on an image display device such as a display but also an operation of projecting an image by a projection device such as a projector. That is, it is described as an image display device that displays an image by projecting an image by a projector.

  For example, the image display device 32 in FIG. 1 is a display, and the image display device 34 is a projector. The image display device 34 projects an image on the region R30 (R34) as a display position. Here, the image display device 30 may be one or plural. That is, it is only necessary to have a configuration capable of displaying at a plurality of display positions. Details of each device will be described in the following functional configuration.

  Furthermore, the image display device 30 may be configured to be movable. For example, in the case of a projector, the projector mounting portion may be configured to move, and the lens direction may be freely operated in the direction in which the projector projects. Moreover, in the case of a display, the attachment part can be moved, and it is good also as a structure which moves to the location to display.

  In the present embodiment, the recognition device 20, the image display device 30, and the control device 10 are connected on the same premises (for example, connected to the same network or connected locally such as USB connection). However, it may be connected via an external network.

  That is, the control device 10 is a server connected to the Internet, and executes processing on the server. The recognition device 20 and the image display device 30 may be connected via the Internet. In this case, the server-side administrator can perform a plurality of controls even at remote locations.

[1.2 Functional configuration]
Next, the functional configuration of each device constituting the image display system 1 in the present embodiment will be described with reference to FIG.

  As shown in FIG. 2, a recognition device 20 and one or a plurality of image display devices 30 are connected to the control device 10.

  The control device 10 includes a control unit 110, a recognition unit 120, an image display control unit 130, and a storage unit 140.

  The control unit 110 is a functional unit for controlling the entire control device 10. The control unit 110 implements various functions by reading and executing various programs stored in the storage unit 140, and includes, for example, a CPU (Central Process Unit).

  The recognition unit 120 is a functional unit for inputting and processing information based on the human body recognized by the recognition device 20. In other words, the recognition unit 20 is a functional unit that recognizes the characteristics of the target person using technology (image processing, thermo, position sensor, pressure sensor) for sensing human movement in the space.

  Here, the characteristic of the subject (person) is a concept including the attributes and actions of the subject. The attributes of the target person are those that can be determined by the recognition device 20 such as height and physique. Furthermore, by recognizing people's size, facial expression, etc., it recognizes whether they are men and women, adults, children, have white canes, use wheelchairs, or are healthy people. be able to.

  In addition, the movement of the target person is to determine the movement of the target person, such as the direction and speed in which the target person is moving, the posture such as whether the target person is standing up, You can recognize things like movement.

  Here, a mechanism in which the recognition device 20 and the recognition unit 120 recognize a person (human body) in the space will be described with reference to FIG. Here, although various apparatuses can be considered as the recognition apparatus 20, a method using Kinect (registered trademark) manufactured by Microsoft Corporation will be described as an example.

  By using Kinect, a human skeleton can be understood as a stick picture (FIG. 3A). That is, the feature points of each joint of the human body and the line connecting the feature points are detected.

  Based on this feature point, it becomes possible to recognize the direction of the human face and the direction of the body. For example, in order to obtain the orientation of the face and the orientation of the body, the feature points of each joint are recognized as shown in FIG. In FIG. 3B, the feature point P01 and the (x, y, z) coordinates of the feature point P02 are detected. Then, the orientation of the face is recognized by calculating the angle between the straight line connecting the two coordinates and the reference plane.

  Further, (x, y, z) coordinates of the feature point P03 and the feature point P04 are detected, respectively, and the body direction (direction and inclination) is determined from the position of the virtual line L01 connecting the feature point P03 and the feature point P04 with a straight line. )

  Thereby, the area | region which displays an image can be pinpointed from the direction which the user is facing, for example. For example, as shown in FIG. 3C, the angle with respect to the central axis is calculated from the feature point P01 and the feature point P02, and thereby the face angle (angle the user faces) θ1 is calculated. Is done.

  Further, it is possible to determine the position at which the line of sight reaches the ground line L04 from the height L02 of the viewpoint of the human body (for example, the height of the feature point P02 approximately) and the normal direction L03 of the face angle. (For example, height L02 × arctan θ1). An image can be displayed using this position as the display region R01.

  Note that other methods may be used as a method of recognizing a human body. For example, an image processing technique using a camera, a recognition technique using thermography or infrared rays, or a pressure sensor may be placed on the floor and a person may be recognized by the direction of the foot and the direction of load. Further, the line of sight may be detected by using a line of sight detection technique.

  Here, the recognition of the orientation of the user P (human body) has a higher priority in the order of the line of sight, the face, and the body. That is, the direction of the line of sight is recognized if the direction of the line of sight can be recognized, the direction of the face if the direction of the face can be detected, and the direction of the body if not. A plurality of these may be recognized, or the direction may be recognized alone.

  Subsequently, the image display control unit 130 is a functional unit for controlling display of an image with respect to one or a plurality of connected image display devices 30. Here, the displayed image can be displayed at a plurality of display positions. The display position is determined by a display area where one image display device 30 can be switched, or is determined by switching the image display device to be displayed. That is, a plurality of display positions may be configured by combining the display area and the image display device.

  Here, the image display device 30 is a device capable of displaying an image such as a display device such as a liquid crystal display or an organic EL display, or a projection device such as a projector. The image in the present embodiment is a concept including a moving image as well as a still image such as a character, a figure, and a photograph. In FIG. 2, an image display device 32 and an image display device 34 are connected.

  Here, an image display control method of the control device 10 using the image display device 30 will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram when the image display device 30 has a wide displayable area like a projector.

  That is, a region R30 is secured as a region where the projector can display. This region R30 can be set on a wall surface or floor surface, and any display region can be used as a display position as long as it is a displayable region. For example, when three areas such as the display area R30a, the display area R30b, and the display area R30c are set, an image is displayed in the display area R30a that is the direction in which the user P is facing.

  The displayable area can be realized in the same way by dividing the display screen into a plurality of areas, for example, in the case of a large liquid crystal display.

  In this embodiment, the display area corresponding to the display position is set in advance as shown in FIG. 4, but any coordinates may be used. That is, an arbitrary position in the displayable area may be set as the display position by designating the vertex coordinates, size, and the like of the display area.

  FIG. 5 shows an example in which a plurality of image display devices and display areas are set in combination as the display position. For example, as the image display device 30, image display devices 32 and 34 that are projectors are connected, and an image display device 36 that is a liquid crystal display is further connected.

  Further, the image display device 32 can display in the display region R32a and the display region R32b and a plurality of display regions, and the image display device 34 can display an image in the display region R34 as a display position. Further, an image can be displayed on the image display device 36. That is, an image can be displayed at four display positions of the display areas R32a, R32b, R34, and the image display device 36. This makes it possible to appropriately display an image at a display position in the direction in which the user P is facing.

  The storage unit 140 is a functional unit that stores various programs and various data necessary for the operation of the control device 10. The storage unit 140 includes, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  The storage unit 140 stores a display position table 142. An example of the display position table 142 is shown in FIG.

  The display position table 142 is a table that stores the characteristics of the subject (for example, human body attributes in the present embodiment) and the display positions in association with each other. For example, when the human body attribute is “160 cm or more”, the display position is R32a. Here, the human body attribute is information about the recognized human body. For example, as shown in the present embodiment, it may be a height or a physique (for example, “slim”). Further, information such as “male”, “female”, “children”, and “adults”, and information such as “wearing a hat” may be used. That is, any information that can be recognized by the control device 10 via the recognition unit 120 (the recognition device 20) may be used.

  Further, the display position table 142 may store the display position together. For example, coordinates in the space are set, and where the display position in the space is provided is stored as coordinates. Thereby, for example, it is possible to determine the display position corresponding to the direction in which the user P is facing, and it is possible to specify the image display device 30 corresponding to the display position.

[1.3 Process flow]
Next, the flow of processing in this embodiment will be described. First, when a human body is detected (step S102; Yes), a human body recognition process is executed (step S104). In the present embodiment, feature points corresponding to joints and the like are detected by the human body recognition process, and the orientation of the human body is recognized.

  Subsequently, after each feature point is recognized, a characteristic determination process is executed (step S106). In this embodiment, the attribute of the human body is determined as one of the characteristics, and the height is mainly determined. Since it is only necessary to finally be able to determine the height, for example, an apparatus capable of recognizing only the height by an infrared sensor or the like may be used.

  Subsequently, display position determination processing is executed from the height determined by the characteristic determination processing (step S108). By the display position determination process, an area in which an image is displayed is determined. Then, an image is displayed in the determined display area (step S110).

  Here, the display position determination process can determine the display position based on the determined height of the user (human body).

  Note that the process including the human body recognition process (step S104) and the characteristic determination process (step S106) may be executed once at the timing when the user is detected, or may be interrupted by a predetermined timer. (For example, every 3 seconds, every 5 seconds).

[1.4 Application examples and effects]
For example, FIG. 8 will be described as an example. The image display device 32 can display an image on the display region R32a and the display region R32b. Here, the area may be switched by changing the area displayed by the image display device 32, or the image display device 32 may be physically moved to switch the display area.

  Here, as shown in FIG. 8A, when the user P1 enters the detection area, the height is determined to be L1. For example, when L1 is 170 cm, an image is displayed in the display region R32a. As a result, an image is displayed in the display area R32a corresponding to the position of the line of sight of the user P1, and the user can easily view it.

  Further, as shown in FIG. 8B, when the user P2 enters the detection area, the height is recognized as L2. For example, when L2 is 150 cm, an image is displayed in the display region R32b. As a result, an image is displayed in the display region R32b corresponding to the position of the line of sight of the user P2, and the user P2 can easily view it.

  Thus, according to the present embodiment, the display position of the image can be changed according to the human body attribute as the determined characteristic of the subject. This can solve the problem that, for example, a user whose height is small is often a child, so that even if an image is displayed at a position that can be recognized by an adult, it is difficult to visually recognize the image.

  In the present embodiment, the recognition of the human body attribute (height) has been described as two stages for convenience of explanation, but it may be further set in a plurality of stages. In addition, when the display area is variable (for example, set by coordinates), it is possible to display an image at a more appropriate position by calculating the coordinates based on the height.

[2. Second Embodiment]
Next, the second embodiment will be described. The second embodiment is an embodiment in the case where the display message is changed based on the human body attribute determined as the characteristics of the target person.

[2.1 Functional configuration]
First, the functional configuration in the present embodiment will be described. Since the system configuration and functional configuration in this embodiment are the same as those in the first embodiment, detailed description thereof is omitted. The difference from the first embodiment is that the data contents stored in the display position table 142 are different as shown in FIG.

  FIG. 9 is an example of data stored in the display position table 142 in the present embodiment. As shown in FIG. 9, the display position (for example, “R32a”) and the display message (for example, “Please prepare admission ticket”) are associated with the human body attribute (for example, “adult”). I remember it.

  Here, the display message may display a sentence such as a sentence or a word, and may include a sign such as a symbol or an arrow. Moreover, what is notified to the user, such as animation display or video display, is included.

  Here, the attributes of “adult” and “child” may be determined by, for example, height. For example, the height “160 cm or more” is determined as “adult”, and the height “less than 160 cm” is determined as “child”. Furthermore, it is possible to more accurately determine “adult” and “child” by executing face recognition processing. Similarly to the first embodiment, the display position and the display message may be simply stored in association with the human body attribute such as height.

[2.2 Process flow]
Next, FIG. 10 will be described regarding the flow of processing in the present embodiment. The process of FIG. 10 is a process in which FIG. 7 in the first embodiment is adapted to this embodiment. Common processes are denoted by common reference numerals and description thereof is omitted.

  That is, by executing the processing up to step S108, the display position is determined based on the human body attribute of the user recognized by the human body recognition processing. Here, a display message determination process for determining a display message is executed (step S202). Then, based on the display position determined in step S108 and the display message determined in step S202, the process displayed in step S110 is executed.

[2.3 Application examples and effects]
An application example of this embodiment will be described with reference to FIG. FIG. 8A shows a case where the user P1 is determined to be an adult. In this case, referring to the display position table 142 of FIG. 9 in the present embodiment, “Please prepare an admission ticket” is displayed as a display message at the display position of R32a.

  FIG. 8B shows a case where the user P2 is determined to be a child. In this case, with reference to the display position table 142 of FIG. 9 in the present embodiment, “Please enter with the cheering person” is displayed as a display message at the display position of R32b.

  As described above, according to the present embodiment, not only the image including the display message is displayed at an appropriate position according to the target person, but also the content of the displayed image (the content of the display message) can be changed. It becomes.

  This makes it possible to display a message corresponding to the human body attribute. For example, in the case of a child, it is possible to convey the message more appropriately by writing the message content to the child (for example, hiragana notation).

[3. Third Embodiment]
Subsequently, the third embodiment will be described. The third embodiment describes an embodiment in which a display message is displayed as necessary in the second embodiment.

  That is, in the operation flow of FIG. 10, only when the display message corresponding to the characteristic (human body attribute) determined in step S106 is stored in the display position table 142, that is, when the condition is met, the image (display message). Is output.

  FIG. 11 shows a display position table 142 in the present embodiment. For example, in the case of “cap” as the human body attribute, a display position (for example, “R32”) and a display message (for example, “take off the hat”) are stored.

  In this case, the message is displayed only when a person wearing a hat (cap) is recognized as a human body attribute. When a plurality of human body attributes are stored, the corresponding messages may be combined and output as an image, or only high priority messages may be output.

  A plurality of display positions may be designated. For example, as shown in FIG. 11, when it is determined that the person is less than 140 cm, a warning “You cannot ride this vehicle!” Is displayed. At this time, for example, display messages (images) can be displayed at a plurality of display positions by designating the display positions as R32a and R32b.

  In addition, display effects such as adding effects to the screen (for example, blinking the screen, displaying large characters), and outputting sound may be stored together.

[4. Fourth Embodiment]
Subsequently, a fourth embodiment will be described. The fourth embodiment is an embodiment in which, in the second embodiment, a motion that is a human movement is further recognized as a characteristic, and a display message and a display position are changed according to the motion.

  The operation flow of this embodiment is shown in FIG. The operation flow of FIG. 12 is obtained by adding step S302 to the operation flow of the second embodiment shown in FIG. In addition, the same code | symbol is attached | subjected to the common process and the description is abbreviate | omitted.

  Here, the motion recognition processing (step S302) is processing for recognizing the motion of the subject as motion information. For example, in the present embodiment, the moving speed and moving direction of the target person are recognized as the operation information. This is calculated based on the information recognized in the human body recognition process (step S104). The human body recognition process (step S104) and the action recognition process (step S302) are processes that are repeatedly executed by a predetermined timer. For example, it is a process that is executed every 0.5 seconds, every second, or executed by executing an interrupt process at a timing when an operation is detected.

  Then, the recognized human body attributes and motion information are determined as the characteristics of the target person (step S106).

  FIG. 13 shows a display position table 142 in the present embodiment. For example, as an example of characteristics, a movement speed (for example, “0 km / h to 5 km / h”), a display position (for example, “R32a”), and a display message (for example, “Welcome!”), Which are operation information. It is stored in association.

  As a result, for example, a message is displayed when approaching the display area R32a, but a message corresponding to the speed (for example, a message that displays “Please do not rush to enter because it is too fast, and alert you)” Is displayed in a different display position (for example, “Thank you.”) Because it is moving in the reverse direction (because the movement speed is negative and the movement direction is recognized as reverse) (R34) can also be displayed.

  In addition, as shown in FIG. 14, by storing the human body attributes in combination as characteristics, for example, a different message may be displayed based on the human body attributes.

  Specifically, when it is determined that “adult” “moving speed is 5 km / h or more” as the characteristics of the target person, “please enter without rushing” is displayed. Further, when it is determined that “children” and “moving speed is 5 km / h or more” as the characteristics of the target person, “Don't hit!

  As described above, when the target person is a child, for example, if the message “Please enter without hurrying” is displayed, the target child may not be able to read (or cannot be determined instantaneously). However, it is possible to display an appropriate message for the target person by displaying the message “Don't worry if you do it!” According to the determined characteristics of the target person.

[5. Fifth Embodiment]
Subsequently, a fifth embodiment will be described. In the fifth embodiment, an embodiment in which the direction of the line of sight is further recognized as the characteristics of the subject in the first embodiment and the fourth embodiment will be described.

  That is, in the action recognition process (step S302) in FIG. 12, the direction in which the user is facing is recognized. Then, a message (image) is displayed in the display area in the direction facing the user.

  FIG. 15 shows a display position table 142 in the present embodiment. For example, as the characteristics, the image display device and the display area are stored in association with the human body attribute of the subject and the direction of the line of sight of the subject. Although not shown in FIG. 15, display messages may be stored.

  For example, as shown in FIG. 16, if the human body attribute of the user P1 is less than 160 cm and the direction in which the user P1 is facing is the X1 direction, a message (image) is displayed in the display area R32b of the image display device 32. In addition, if the human body attribute of the user P2 is 160 cm or more and the facing direction is the X3 direction, a message (image) is displayed on the image display device 34 (display region R34).

  Thus, according to the present embodiment, a message is displayed at an appropriate position. Further, by storing the message contents, it is possible to display an appropriate message at an appropriate position for the user.

[6. Sixth Embodiment]
Subsequently, a sixth embodiment will be described. The sixth embodiment is an embodiment when a plurality of users are detected. For example, although FIG. 16 demonstrated using user P1, P2, this is embodiment when this exists in the same area. Here, the recognition device 20 and the recognition unit 120 can detect a plurality of users (humans).

  In the present embodiment, the characteristics (for example, human body attributes and motion information) of the users P1 and P2 are detected. As a result, the message (image) viewed by the user P1 is displayed on R32a, and the message (image) viewed by the user P2 is displayed on R34. In addition, when Kinect mentioned above is used, it can detect to six people simultaneously.

  In the operation flow of FIG. 17, when a human body is first detected (step S102; Yes), a human body recognition process is executed (step S104). Here, if there is another human body to be detected, all human body recognition processing is performed (step S402; Yes → step S104).

  When all detected human bodies are recognized (step S402; No), motion recognition processing for all detected human bodies is executed (step S404). Then, based on the recognized human body and the motion information, the characteristic determination process for all the target persons is executed (step S406). Here, characteristics (human body attributes, motion information) are obtained for all target persons.

  Next, the display position is determined based on the determined characteristics (human body attributes, motion information) (step S108). An image (message) is displayed based on the determined display position (step S110). The process of displaying this image is performed for the detected human body (step S408; Yes). Then, when all the processes are finished, this process is finished (step S408; No).

  This process may be executed once or a plurality of times. That is, it may be repeatedly executed as a loop process, or may be periodically executed using a timer. The screen displayed in step S110 may be a screen corresponding to the user.

  In addition, as the characteristics of the target person, only one process (for example, only human body attributes) may be processed.

[7. Seventh Embodiment]
Next, a seventh embodiment will be described. Although the above-described embodiment has described the embodiment for changing the display position, the seventh embodiment describes the embodiment for changing the means for outputting a message.

  Specifically, when a special characteristic (special attribute) is recognized in the characteristic determination process, the display position is not determined and a notification means other than the display means such as a speaker is selected. Then, for example, instead of the display in step S110 in FIG.

  For example, if the white cane is determined as a special attribute, it is determined that the user is a visually impaired person. In this case, instead of displaying the message (or simultaneously), a message is output by voice through a speaker.

[8. Modified example]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also within the scope of the claims. include.

  In the above-described embodiments, the processes are described separately for the convenience of explanation, but it is needless to say that they may be combined and operated within a possible range.

  In addition, the program that operates in each device in the embodiment is a program (a program that causes a computer to function) that controls the CPU and the like so as to realize the functions of the above-described embodiments. Information handled by these devices is temporarily stored in a temporary storage device (for example, RAM) at the time of processing, then stored in various ROM or HDD storage devices, and read and corrected by the CPU as necessary. -Writing is performed.

  Here, as a recording medium for storing the program, a semiconductor medium (for example, ROM, a non-volatile memory card, etc.), an optical recording medium / a magneto-optical recording medium (for example, a DVD (Digital Versatile Disc), MO (Magneto Optical), etc. Disc), CD (Compact Disc), BD, etc.), magnetic recording medium (for example, magnetic tape, flexible disk, etc.), etc. In addition, by executing the loaded program, not only the functions of the above-described embodiment are realized, but also based on the instructions of the program, the processing is performed in cooperation with the operating system or other application programs. The functions of the invention may be realized.

  In addition, when distributing to the market, the program can be stored and distributed in a portable recording medium, or transferred to a server computer connected via a network such as the Internet. In this case, of course, the storage device of the server is also included in the present invention.

  In addition, a part or all of each device in the above-described embodiments may be realized as an LSI (Large Scale Integration) that is typically an integrated circuit. Each functional block of each device may be individually chipped, or a part or all of them may be integrated into a chip. Further, the method of circuit integration is not limited to LSI, and may be realized by a dedicated circuit or a general-purpose processor. In addition, when integrated circuit technology that replaces LSI appears due to progress in semiconductor technology, it is of course possible to use an integrated circuit based on this technology.
