Description

  The present invention relates to an information presentation system, an information presentation method, an information presentation program, and a storage medium for displaying content information such as advertisements on an information presentation device installed in a target space, for example.

  As an advertising technique in a public space, a method of posting a large poster in a place with a lot of traffic and a method of displaying a video content composed of a still image or a moving image on a large screen display are generally used. However, although these methods are designed to stand out as much as possible for a large number of unspecified people, they post or display the same information in the same place, so people are advertised. It is difficult to keep the advertisement recognition rate high.

  Therefore, an electronic advertisement system that authenticates an individual and presents individual advertisement information to the individual has been proposed. With this system, it is possible to realize information presentation useful for both the advertisement viewer and the information presenter (see, for example, Patent Document 1).

JP 2002-150130 A

  However, since the previously proposed system requires personal authentication, if there is no consensus regarding personal information between the advertisement viewer and the information presenter, the advertisement viewer is presented with information addressed to the individual. May be anxious or uncomfortable with things, and may refuse.

  The present invention has been made paying attention to the above circumstances, and its purpose is to provide an information presentation system, an information presentation method, and the like that enable information presentation with a high recognition rate without using personal authentication while targeting an individual. It is to provide an information presentation program and its storage medium.

  In order to achieve the above object, one aspect of the present invention includes an information presentation device that displays content information for a person installed in a target space and acting in the target space, and the person and the information presentation device in the target space. An imaging device that captures a range, an information management device that stores a plurality of pieces of information with different levels of detail constituting the content information, and a control device connected to the information presentation device, the imaging device, and the information management device In the system, the control device determines the distance of the person relative to the information presentation device and the change thereof as information representing the positional relationship between the information presentation device and the person based on the image data captured by the imaging device. To detect. Then, according to the detected distance and the change thereof, the detail level of the content information is variably set so that the detail level of the content information increases as the distance approaches, and the detail level of the variable information is supported. Information to be read is selectively read from the information management device, and the read information is displayed on the information presentation device.

  Therefore, when a person enters the target space, information indicating the positional relationship between the person and the information presentation device is detected based on the captured image of the person, and information addressed to the person is determined based on the detection information. It is displayed on the information presentation device. That is, for example, it is possible to present information as if it were addressed to a person who is walking in the target space, and thus it is possible to present information addressed to the individual without using personal authentication. .

  Moreover, as information representing the positional relationship between the person and the information presentation device, the distance of the person with respect to the information presentation device and its change are detected, and the information is selected so that the level of detail of the content information increases as this distance approaches. Is displayed. For this reason, for example, when the passerby is away from the information presenting device, information with high eye catching elements that attract the passerby's interest is displayed first, and when the passerby approaches the information presenting device, Detailed information is displayed instead of information with high eye-catching elements. For this reason, it is possible to increase the passerby's recognition rate for content information compared to the case where uniform content information is always displayed.

Further, one aspect of the present invention is characterized by further including various characteristic components as described below.
The first characteristic component moves the display position of the content information in the vertical direction on the display screen of the information presentation device from the upper side to the lower side as the distance approaches in accordance with the detected distance and the change thereof. To control.
In this way, for example, when the passerby is away from the information presentation device, the content information is displayed on the upper side of the display screen of the information presentation device, and when the passerby approaches the information presentation device, the display position of the content information is displayed. Moves to the lower side of the display screen of the information presentation device. For this reason, it is possible to display the information content at an upper position as easy as possible for a passerby who is far from the information presentation device, and when the passerby approaches the information presentation device, the display position of the content information is displayed on the display screen. Since it moves to the lower position, it becomes possible to display content information addressed to other passers-by who are far away from the passer-by on the upper side of the display screen. In other words, the display screen of the information presentation device can be divided into regions for display to a plurality of passersby.

The second characteristic component controls the display size of the content information on the display screen of the information presentation device so as to increase as the distance approaches in accordance with the detected distance and its change.
If it does in this way, it will become possible to display the detailed information of content information in the state where it is easy to see to the person near the information presentation device.

The third characteristic component detects the position of the person in the left-right direction with respect to the information presentation device and its change based on the image data captured by the imaging device. Then, according to the detected horizontal position and its change, the horizontal display position of the content information on the display screen of the information presentation device is controlled to correspond to the detected horizontal position of the person. Is.
If it does in this way, the display position of the content information addressed to the said passerby will move on the display screen of an information presentation apparatus with the movement of a passerby, for example. For this reason, the passerby can view the content information without moving the line of sight while moving. In particular, when a plurality of display panels are arranged side by side in the movement direction of the passerby, when content information addressed to the passerby is sequentially moved and displayed on the plurality of display panels as the passerby moves, the passerby Since the same content information can be visually recognized over a relatively long time while moving, it is more effective in increasing the information recognition rate.

  That is, according to the present invention, it is possible to provide an information presentation system, an information presentation method, an information presentation program, and a storage medium thereof that enable information presentation with a high recognition rate without using personal authentication while targeting an individual. .

It transmits to the information presentation control device SV.

  The information management device MS is composed of, for example, a storage server having a large-capacity memory, and stores a plurality of pieces of content information such as advertisements to be presented to the user. These pieces of content information are composed of a plurality of pieces of information having different levels of detail. The level of detail is represented by, for example, four levels. The information in the first stage is composed of information with high eye-catching elements that attract the passerby's interest. The second-stage information is composed of a character string that conveys the outline of the image and the content, and the third-stage information is composed of a character string that represents the outline of the content in a short sentence. The information of the fourth stage is configured by more detailed information or related information of the content.

The information presentation control device SV is composed of, for example, a personal computer or a server computer, and is configured as follows. FIG. 2 is a functional block diagram showing the configuration of the hardware and software.
That is, the information presentation control device SV includes a central control unit (CPU) 11. The CPU 11 is connected to the program memory 13, the data memory 14, the camera interface (camera I / F) 15, the display interface (display I / F) 16, and the external storage interface (external storage I / F) via the bus 12. 17 is connected.

  Under the control of the CPU 11, the camera I / F 15 receives the image data transmitted from each of the stereo cameras CM <b> 1 to CMn via the communication network LN and stores it in the data memory 14. The display I / F 16 transmits content information to each of the displays DP1 to DPn via the communication network LN under the control of the CPU 11. As a communication protocol, for example, TCP / IP (Transmission Control Protocol / Internet Protocol) is used. The external storage I / F 17 performs processing for reading content information to be displayed from the information management device MS under the control of the CPU 11 and processing for storing new content information and related information in the information management device MS. Do.

  The program memory 13 includes, as application programs necessary for carrying out the present invention, a human body action acquisition control program 131, a display position / size setting control program 132, a detail level setting control program 133, and a content display control program. 134 is stored.

  The human body action acquisition control program 131 receives the image data transmitted from the stereo cameras CM1 to CMn via the camera I / F 15 at regular time intervals, analyzes the received image data, and displays the image data for the displays DP1 to DPn. The CPU 11 is caused to execute a process for detecting a passerby's action state. The parameters detected as the passerby's behavior include the presence or absence of a passerby, the distance between the detected passerby and the displays DP1 to DPn and their changes, and the position of the passerby in the horizontal direction with respect to the displays DP1 to DPn. And their changes. For the detection of each parameter, for example, pattern matching processing for an image and processing for calculating the distance between detected image patterns based on the number of pixels are used.

The display position / size setting control program 132 causes the CPU 11 to execute the following processes.
(1) Based on the distance between the detected passers-by and the displays DP1 to DPn and their changes, the display position of the content information on the display screen of each display DP1 to DPn is changed in the vertical direction as the distance approaches. Processing to variably set so as to move from the upper side to the lower side.
(2) Based on the distance between the detected passers-by and the displays DP1 to DPn and changes thereof, the size of the display window for displaying the content information on the display screen is increased as the distance gets closer. Processing to variably set.
(3) Based on the detected position of the passerby in the horizontal direction of the displays DP1 to DPn and the change thereof, the display position of the content information in the horizontal direction on the display screen of the displays DP1 to DPn is determined as the detected passerby. The process of variably setting to correspond to the position in the left-right direction.

  The detail level setting control program 133 is based on the distance between the detected passers-by and the displays DP1 to DPn so that the detail level of the content information to be displayed increases as the distance decreases. The CPU 11 is caused to execute a process for variably setting.

The content display control program 134 causes the CPU 11 to execute the following processing.
(1) Based on the level of detail of the content information variably set by the level of detail setting control program 133, information at a stage corresponding to this level of detail is selectively transmitted from the information management device MS via the external storage I / F 17. Read process.
(2) Display for displaying the read information on the basis of information specifying the vertical and horizontal display positions and the display window size variably set by the display position / size setting control program 132 A process of generating data and transmitting the generated display data from the display I / F 16 to a display to be displayed.
(3) When a display request for fourth-stage information is sent from the touch panel of the displays DP1 to DPn while the display data is being displayed, the requested information is sent from the information management device MS to the external storage I / F 17. Selectively read out via. And the process which produces | generates the display data for displaying this read-out information, transmits this produced | generated display data to the display of a display object from display I / F16, and displays it. Even when the fourth stage information is displayed, the display data is based on the information indicating the vertical and horizontal display positions and the window display size variably set by the display position / size setting control program 132. Is generated.

  The data memory 14 is composed of, for example, a RAM, and the CPU 11 performs image analysis processing, display data generation processing, and the like in accordance with the functions for temporarily storing image data sent from the stereo cameras CM1 to CMn and the control programs 131 to 134 described above. Function as a working memory.

Next, the operation of the information presentation system configured as described above will be described according to the control procedure of the information presentation control device SV. FIG. 3 is a flowchart showing the control procedure and control contents of the information presentation control device SV.
The information presentation control device SV activates the human body action acquisition control program 131 in step S31, and captures image data from each of the stereo cameras CM1 to CMn at a constant cycle, for example. The captured image data is stored in the data memory 14. Subsequently, in step S32, the information presentation control device SV detects an image pattern corresponding to a passerby from each of the acquired image data, and a passerby exists in front of the displays DP1 to DPn based on the detection result. It is determined whether or not to do. As a result of this determination, if there is a display for which it is determined that there is no passerby, the content display control program 134 is activated in step S37, and image content such as a predetermined landscape is obtained from the information management device MS. read out. Then, the display data of the read image content is transmitted to the corresponding display in step S38 and displayed.

  On the other hand, it is assumed that a passerby is detected in an area in front of an arbitrary display (for example, DP2) as a result of the determination. In this case, the information presentation control device SV activates the human body action acquisition control program 131 again in step S33, performs image processing on the image data stored in the data memory 14, and detects the detected passers-by. The distance between the display DP2 and the change thereof, and the position of the passerby in the left-right direction with respect to the display DP2 and the change thereof are detected. When a plurality of passers-by are detected in the area in front of the display DP2, the distance between the passer-by and the display DP2 and the change of each passer-by and the right and left of the passerby with respect to the display DP2 The direction position and its change (movement) are detected.

  Subsequently, the information presentation control device SV starts the detail level setting control program 133. Then, based on the distance between the detected passerby and the display DP2, the detail level of the content information is set so that the detail level of the content information to be displayed increases as the distance decreases.

  For example, as shown in FIG. 6, the separation distance from the display DP2 is divided into three areas L1 to L3, and the detail information F1 is displayed for the passerby C present in the area L1 farthest from the display DP2. Set. Further, the content information presented to the passerby B present in the region L2 at an intermediate distance to the display DP2 is presented to the detail level F2, and further to the passerby A present in the region L3 closest to the display DP2. The content information is set to the detail level F3.

  Then, the information presentation control device SV activates the content display control program 134 in step S34. Then, information corresponding to the set level of detail is selectively read out from a plurality of pieces of information constituting the content information to be presented to the passerby. For example, when the degree of detail F1 is set, the first-stage information with a high eye-catching element that attracts the passerby's interest is read out. In addition, when the detail level F2 is set, the second-stage information including the image and the character string that conveys the content overview is read, and when the detail level F3 is set, the content overview is read out. Is read in the third stage character string information. The read information is temporarily stored in the data memory 14.

  Next, the information presentation control device SV activates the display position / size setting control program 132 in step S35. Based on the distance between the detected passers-by and the displays DP1 to DPn, the display position of the content information in the vertical direction on the display screen of the display DP2 is set.

  For example, as shown in FIG. 6, with respect to the content information presented to the passerby C existing in the region L1 farthest from the display DP2, as shown in FIG. 7C, the window display position is set to the upper position on the display screen. Set as follows. For the content information presented to the passerby B present in the area L2, the window display position is set to the middle position in the vertical direction of the display screen as shown in FIG. The content information to be presented to the passerby A existing in the region L3 closest to the DP2 is set so that the window display position is the lower position of the display screen as shown in FIG.

Further, the information presentation control device SV uses the display position / size setting control program 132 to display the display size of the window for displaying the content information on the display screen based on the detected distance between the passerby and the display DP2. (Area) is variably set.
For example, for the content information presented to the passerby C present in the region L1 farthest from the display DP2 as shown in FIG. 6, the display size of the window is set to a small value as shown in C of FIG. As for the content information presented to the passerby B present in the area L2, the window display size is set to a medium size as shown in FIG. 7B, and the area L3 closest to the display DP2 is set. For the content information presented to the existing passerby A, the display size of the window is set to the largest size as shown in A of FIG.

  As a specific example of the window size, the window area corresponding to a passerby closest to the display is set to be about 1/4 to 1/3 of the total display area of the display. It is desirable to set the window area corresponding to the passerby farthest from the display to be about 1/16 to 1/8 of the total display area of the display.

  In addition, when a plurality of windows corresponding to different passers-by are partially displayed on one display, the window corresponding to the passer-by who is closest to the display is displayed on the upper layer side and is farther from the display. The window corresponding to the passerby at the position is controlled to be displayed on the lower layer side.

  Further, the information presentation control device SV uses the display position / size setting control program 132 to determine the right and left direction of the content information on the display screen of the display DP2 based on the detected horizontal position and movement of the passerby with respect to the display DP2. The display position of is variably set.

  For example, as shown by “1” in FIG. 4, when a passerby is present on the right side of the display DP2 in the course of movement, the display position of the content information presented to the passerby is changed to “1” in FIG. As shown in "", it is set to be displayed on the right side of the display screen of the display DP2. Further, as shown by “2” in FIG. 4, when a passerby exists or moves in front of the display DP2, the display position of the content information presented to the passerby is shown as “2” in FIG. The display DP2 is set to be displayed at the center of the display screen. Furthermore, when the passerby is present or moved to the left front position of the display DP2 as indicated by “3” in FIG. 4, the display position of the content information presented to the passerby is indicated by “3” in FIG. In this way, the display DP2 is set to be displayed at the center of the display screen.

  Then, when the display position of the content information on the display DP2 and the size of the display window are set, the information presentation control device SV activates the content display control program 134. Then, based on the information specifying the set display position and display window size, display data for displaying the content information previously read in step S34 and stored in the data memory 14 is generated. The generated display data is transmitted from the display I / F 16 to the display DP2 to be displayed and displayed.

  In step S36, the information presentation control device SV determines whether or not the passerby still exists before the display DP2 based on the latest image data. If it still exists, the process returns to step S33, and the series of content information display control described above in steps S33 to S36 is repeatedly executed for the passerby.

  Thus, as long as there is a passerby in the area in front of the display DP2, the content information in which the degree of detail is set according to the distance from the passer's display DP2 is the distance from the passer's display DP2. Are displayed according to the vertical and horizontal display positions set according to the horizontal position and the size of the display window.

  Therefore, according to the present embodiment, for example, when a passerby passes a position away from the display DP2, information on the high degree of detail F1 of an eye-catching element that first attracts the passerby as a first step is As shown in C in FIG. 7, the window is displayed in a small window size at a position on the upper side and on the right side of the display DP2. Then, when a user who is interested in this display information approaches the display DP2, as shown in B in FIG. In the middle of the display DP2, a medium window size is displayed at a position on the left side. When the passerby further approaches the display DP2, information corresponding to the degree of detail F3 representing the outline of the content in a short sentence as a third stage is displayed at a position below the display DP2 as indicated by C in FIG. And it is displayed with a large window size in the center.

  That is, when the passerby passes in front of the display DP2, the display of the content information is started on the display DP2 at that time, so that the passerby recognizes as if the content information was displayed to himself / herself. And as a passerby who is interested approaches the display DP2, information with a high degree of detail is displayed in a large window in stages, so that the passerby can confirm content information step by step without difficulty. .

  When the passerby performs an operation for requesting display of more detailed information or related information on the touch panel of the display, the request is notified to the information presentation device SV. When receiving the request, the information presentation control device SV reads out the corresponding information from the information management device MS as the fourth stage, and transmits the read detailed information or related information from the display I / F 16 to the display DP2. As a result, the detailed information or related information is displayed on the display. In this case, detailed information or related information may be displayed on the full screen. Therefore, the passerby can additionally acquire detailed information or related information regarding the content that the user is interested in on the spot.

Furthermore, in the system of this embodiment, when a passerby moves from one display to the next display, the display of the content information displayed on the display before the movement can be taken over by the display after the movement. Is possible.
For example, as shown in FIG. 8, when the passerby moves from the area E21 to E23 in front of the display DP2 to the area E31 to E33 in front of DP3, the passerby is imaged by the stereo camera corresponding to the display DP3. The information presentation device SV detects the distance between the passerby and the display DP3 and the position in the left-right direction based on the image data of the stereo camera. Then, the content information set with the level of detail according to the detected distance is read from the information management device MS, and the upper and lower sides of the display screen of the display are determined according to the distance from the passerby display DP2 and the horizontal position. The display position in the direction and the horizontal direction and the size of the display window are set. Based on the set display position and display size, display data of the read content information is generated and displayed on the display DP3.

  Therefore, the same content information is sequentially displayed on each of the displays DP2, DP3, DP4,... As if the passersby moved to wait for the passersby. For this reason, the passerby can check the content information while moving without stopping.

  Further, it is assumed that a passerby moves obliquely and approaches the displays DP3 and DP4 as indicated by the movement trajectories P1, P2, and P3 in FIG. 9, for example. In this case, the information presentation control device SV detects the distance between the passerby and the display for each of the displays DP3 and DP4 as in the case of the display DP2. Then, the content information set with the level of detail according to the detected distance is read from the information management device MS, and further, the vertical and horizontal display positions on the display screen of the display according to the distance and the horizontal position. The display size of the window is set, display data of the read content information is generated based on the set display position and display size, and displayed on the displays DP3 and DP4.

  Therefore, as the passerby moves, the level of detail of the content information displayed on the displays DP3 and DP4 sequentially changes, and the display position and the window display size also change. For this reason, it is possible to confirm the contents of the content information whose level of detail changes step by step, as if the passerby is moving, just as if the user stopped and viewed one display. Become.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the case where the displays DP1 to DP5 are arranged so as to face the direction orthogonal to the traveling direction of the user as illustrated in FIG. In addition, for example, as shown in FIG. 10, the displays DP <b> 1 ′ to DP <b> 5 ′ may be arranged so as to face an oblique direction with respect to the traveling direction of the user. In this way, the user can walk while looking at the displays DP1 'to DP5' obliquely in front rather than directly, thereby making it easier to see the content information displayed on the displays DP1 'to DP5'. It is possible to further increase the user's recognition rate for the content information.

  In addition, the change in the window size and the display position may be either a linear change or an exponential change, but the change in the window size is proportional to the square of the change in the distance between the passerby and the display. It is desirable to set as follows. Furthermore, the shape of the window may be a circle, an ellipse, a triangle, or a polygon other than a rectangle such as a rectangle or a square. The character points of the content displayed in the window may be controlled to change linearly in proportion to the window size.

  Furthermore, in the embodiment, the image data of the stereo cameras CM1 to CMn is used as means for detecting the human body position, but an infrared camera or a millimeter wave radar may be used in addition to using the stereo camera. Of these, when using a millimeter wave radar, it is possible to measure the distance from the display to the human body by providing a radar transmitter / receiver in the frame of the display. There is an advantage that can be made unnecessary.

  In addition, the system configuration of the information presentation system, the configuration of the information presentation control device and its control procedure and control content, the type of the imaging device and the information detection processing method representing human behavior based on the image data, the number of display arrangements, the content The number of levels of detail can be variously modified and implemented without departing from the gist of the present invention.

  In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
