  Embodiments of the present invention will be described below with reference to the drawings.

  Information displays (digital signage) in shopping malls and stations are usually installed on the wall. The information display of the sales floor is installed on a product shelf, a wall, or a sales stand, and a product is arranged in the vicinity.

  Normally, when a customer (viewer, user) travels along a passage, the user moves while looking at these information displays beside the body, and if necessary, stops and looks directly at the contents of the information display. However, when a plurality of information displays are in the vicinity range, the information displays may interfere with each other and may not be able to concentrate on the information on the desired information display. In the present embodiment, at a certain point in time, information is presented with only one information display conspicuous.

<First Embodiment>
FIG. 1 is a configuration diagram of an information presentation system according to the first embodiment. The information presentation system of the present embodiment includes a server 1 (information presentation device) and a plurality of information displays 2 (display devices) installed in the vicinity range. The server 1 and each information display 2 are connected by a network.

  The server 1 illustrated includes a display management unit 11, a reproduction order determination unit 12, a reproduction control unit 13, and a storage unit 14.

  The display management unit 11 updates the registration list stored in the storage unit 14 based on the connection request to the server 1 and the disconnection request transmitted from each information display 2. The information display 2 connected to the server 1 is registered in the registration list.

  The reproduction order determination unit 12 determines the reproduction order of the contents of the plurality of information displays 2 installed in the vicinity. The reproduction control unit 13 specifies the information display 2 for reproducing the content in accordance with the reproduction order determined by the reproduction order determining unit 12, transmits a reproduction command for reproducing the content to the identified information display 2, and other information. The display 2 is transmitted with a stop command for stopping the reproduction of the content or a quiet command for reproducing only the video of the content, and the content is reproduced with only one information display 2 in the order of reproduction.

  The information display 2 includes a playback unit 21 that plays back content in accordance with instructions from the server 1. Examples of content reproduced / presented by the information display 2 include still images and moving images. Content may be stored in a storage unit (not shown) of each information display 2 or distributed via a network. When the moving image content is distributed via the network, the information display 2 performs streaming reproduction.

  Content can be presented continuously when the same information (still image) is presented, or a video image of a certain length is repeated. However, if the storage memory is replaced or new content is distributed over the network It can be rewritten.

  As the server 1 and the information display 2 described above, for example, a general-purpose computer system including a CPU, a memory, an external storage device such as an HDD, an input device, and an output device can be used. In this computer system, each function of each device is realized by the CPU executing a predetermined program loaded on the memory. For example, the functions of the server 1 and the information display 2 are executed by the CPU of the server 1 in the case of the program for the server 1 and the CPU of the information display 2 in the case of the program for the information display 2, respectively. Realized.

  Further, the program for the server 1 and the program for the information display 2 can be stored in a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, a DVD-ROM, or distributed via a network. You can also.

  Next, the processing of this embodiment will be described.

  FIG. 2 is an explanatory diagram showing an overview of the information presentation method of the present embodiment. In this embodiment, the server 1 determines the reproduction order of the plurality of information displays 2 existing in the vicinity range, selects one information display (“B” in the illustrated example) in the determined reproduction order, and selects the selected information. Play content on the display only. While the selected information display (B) is playing, the server 1 controls all other information displays (“A” in the illustrated example) to the stop mode or the silent mode.

  The stop mode stops the reproduction of the content and turns off the information display screen. In silent mode, only video content is played, and no audio is output (promotion). In the quiet mode, it is also possible to change the background to an inconspicuous background tone (such as reducing the tone of the entire image or changing to a whitish image) and playing back only the content of the video.

  The information display (B) transmits an end notification to the server 1 when the reproduction of the content ends. The server 1 instructs the next information display in the reproduction order list to reproduce, and the next information display reproduces the content. By repeating this, in this embodiment, only one information display always reproduces content.

  FIG. 3 is a flowchart of the process of FIG.

  Each of the plurality of information displays 2 in the vicinity range registers the presence / absence in the server 1. In other words, the information display 2 transmits a connection request to the server when activated, and transmits a disconnection request to the server 1 when stopped.

  The display management unit 11 of the server 1 connects to the information display 2 that has transmitted the connection request, and registers the ID (identification information) of the information display 2 in the registration list of the storage unit 14. The connection request includes the ID of the source information display 2.

  The display management unit 11 disconnects the connection with the information display 2 that has transmitted the disconnection request, and deletes the ID of the information display 2 from the registration list in the storage unit 14. Note that the disconnection request includes the ID of the information display 2.

  As a result, the information display 2 that is actually connected to the server 1 is registered in the registration list.

  Then, the playback order determination unit 12 determines the playback order of the contents among the plurality of information displays 2 registered in the registration list, and sets the determined playback order in the registration list (S11). It is conceivable that the reproduction order is determined based on a priority order determined in advance for each information display 2. For example, the server 1 is assumed to include a priority table (not shown) that stores the priority of each information display 2.

  Note that there are various methods for determining the playback order, such as using round robin, setting the registration order in the registration list, and using the position of the information display 2.

  If there is no change in the registration list (S12: YES), the playback control unit 13 uses the registration list in which the playback order is set to specify the information display 2 to be played next, and the specified information display A content playback command is transmitted to 2 and a stop command to stop playback of content or a quiet command to playback only video of content is transmitted to all other information displays 2 (S13).

  As a result, the information display 2 that has received the reproduction command reproduces the content. In the present embodiment, the content reproduced by each information display 2 is divided into, for example, a few seconds to several tens of seconds. In one reproduction, a short portion of the divided content is reproduced, and then another information display 2 shall be given the opportunity for regeneration.

  The other information display 2 to which the stop command or the quiet command is transmitted is in a stop mode in which the screen is turned off without playing back the content, or a quiet mode in which only the content video is played back.

  The information display 2 that has received the playback command transmits an end notification to the server 1 when the playback of the content ends (S14).

  When receiving the end notification, the reproduction control unit 13 of the server 1 determines whether or not the registration list has been changed, that is, whether or not the information display 2 has been registered or deleted (S12). When there is no change in the registration list (S12: YES), the playback control unit 13 uses the playback order of the registration list stored in the storage unit 14 to identify and specify the information display 2 to be played back next. A reproduction command is transmitted to the information display 2, and a stop command or a quiet command is transmitted to the other information display 2 (S13), and the subsequent processing is repeated. When the content reproduction is completed on all the information displays 2, the display returns to the first (first) information display 2, but when there are a plurality of contents to be reproduced on the information display 2, the contents subsequent to the previous one are reproduced. You may decide.

  When there is a change in the registration list (S12: NO), the playback order determination unit 12 re-determines the playback order of the contents in the information display 2 registered in the registration list after the change, and determines the determined playback order. Is set in the changed registration list (S15). The reproduction control unit 13 specifies the information display 2 on which the content is to be reproduced next by using the changed registration list, transmits a reproduction command to the identified information display 2, and stops the other information display 2 with respect to the stop command. Alternatively, a quiet command is transmitted (S13), and the subsequent processing is repeated.

  By repeating the processing of FIG. 3, in the present embodiment, it is possible to create a state in which only one information display 2 appeals at the same time (a state in which content other than the quiet mode is being played back).

  In the present embodiment described above, a plurality of information displays 2 in the vicinity range are treated as one unit, managed by the server 1, and content is reproduced so that only one information display 2 stands out at a certain point in time. In this way, the appeal effect can be enhanced. That is, it is possible to draw attention to one information display 2 by sounding the sound together with the video on only one information display 2 and stopping the other information display 2 in the silent mode.

  Moreover, even in a space where a plurality of information displays 2 exist, it can be produced as a relatively quiet space. Moreover, since the information display 2 in the state of not appealing is in the stop or quiet mode, energy is saved.

  In addition, by making one information display 2 conspicuous, it is possible to increase customer satisfaction, increase recognition of product information, and improve sales of product sales.

  Further, when the content reproduction (promotion) on one information display 2 is finished, the user moves to the content reproduction on the next information display 2 so that the user can display the content appealing to all the information displays 2 as long as there is time. Can watch.

  In this embodiment, the registration list is automatically updated based on the connection request and the disconnection request transmitted from each information display 2, and the playback order is determined based on the updated registration list. However, there is no need to re-determine the playback order individually. In other words, even when the number of information displays is large and the information display 2 is frequently increased or decreased, it is possible to present information suitable for the entire situation without having to deal with them individually.

<Second Embodiment>
In this embodiment, a sensor installed to observe the surroundings of a plurality of information displays in the vicinity range senses the vicinity to detect the customer's position, and controls each information display 2 according to the sensing result (content reproduction) , Stop, quiet mode).

  FIG. 4 is a configuration diagram of an information presentation system according to the second embodiment. The information presentation system of the present embodiment includes a server 1, a plurality of information displays 2 installed in the vicinity, and a sensor 3 (video camera, Infrared human sensor etc.).

  The illustrated server 1 includes a display management unit 11, a playback order determination unit 12, a playback control unit 13, a storage unit 14, and a display selection unit 15. The server 1 of this embodiment differs from the server 1 of the first embodiment (see FIG. 1) in that it has a display selection unit 15. The display selection unit 15 uses the position and traveling direction of the person existing around the plurality of information displays 2 detected by the sensor 3 to select the information display 2 existing in the human field of view from the plurality of display devices. select.

  Further, the playback control unit 13 of the present embodiment specifies and specifies the information display 2 that plays back the content according to the playback order determined by the playback order determination unit 12 from the information display 2 selected by the display selection unit 15. A reproduction command is transmitted to the information display 2, and a stop command or a quiet command is transmitted to the other information display 2 in the selected information display 2, and 1 in the order of reproduction in the selected information display 2. The content is reproduced by only one information display 2.

  In addition, each information display 2 of the present embodiment is the first in that when transmitting a connection request to the server at the time of activation, the position information (X, Y) where the information display 2 is installed is also transmitted. Unlike the information display 2 of the embodiment, the rest is the same as that of the first embodiment. Thereby, the display management unit 11 of the server 1 connects to the information display 2 that transmitted the connection request, and registers the ID and position information of the information display 2 in the registration list of the storage unit 14. Thereby, the position information of the information display 2 actually connected to the server 1 is registered in the registration list.

  FIG. 5 is an explanatory diagram showing an overview of the information presentation method of the present embodiment. In the present embodiment, the sensor 3 senses the surroundings of the plurality of information displays 2, detects the position and traveling direction of the customer, and transmits it to the server 1.

  As shown in FIG. 5, when the customer approaches a plurality of information displays 2, the display selection unit 15 sets the view range calculated based on the customer's position and traveling direction, and a predetermined viewing angle and distance. The information display 2 located inside is selected. For the position of each information display 2, the registration list in the storage unit 14 is referred to.

  On the other hand, when the traveling direction of the customer moves away from the plurality of information displays 2 (not viewing the information display 2), the display selection unit 15 does not select any information display 2.

  FIG. 6 is a flowchart showing the processing of FIG.

  First, when the sensor 3 detects a customer around the plurality of information displays 2, the position and traveling direction of the customer are input to the server 1 (S21). The display selection unit 15 of the server 1 determines whether the customer is moving toward the information display 2 using the traveling direction acquired from the sensor 3 (S22). When moving in a direction away from the information display 2 (S22: NO), the reproduction control unit 13 transmits a stop command or a quiet command to all the information displays 2, and sets all the information displays 2 to the stop or quiet mode. Control (S25).

  When moving closer to the information display 2 (S22: YES), the display selection unit 15 is located within the field of view calculated based on the customer's position and traveling direction, and a predetermined viewing angle and distance. The information display 2 is selected (S23). In the example shown in FIG. 5, the information display 2 from “2” to “6” is selected.

  For the information display 2 outside the visual field range (S23: NO), the reproduction control unit 13 transmits a stop command or a quiet command, and controls the information display 2 to the stop or quiet mode (S26).

  For the information display 2 within the field of view (S23: YES), as described in the first embodiment (see FIG. 3), the content is reproduced using the reproduction order of the registration list stored in the storage unit 14. The information display 2 to be specified is specified, a reproduction command is transmitted to the specified information display 2, and a stop command or a quiet command is transmitted to the other information display 2 in the order of reproduction in the selected information display 2. The content is reproduced with only one information display 2 (S24).

  FIG. 7 is an explanatory diagram showing an outline of an information presentation method when a customer moves left and right with respect to a plurality of information displays 2. The display selection unit 15 selects the information display 2 (in the example of FIG. 7, the information display 2 of “1” to “3”) in the view range in the traveling direction.

  FIG. 8 is a flowchart showing the processing of FIG.

  First, when the sensor 3 detects a customer around the plurality of information displays 2, the position and traveling direction of the customer are input to the server 1 (S31). The display selection unit 15 of the server 1 uses the traveling direction acquired from the sensor 3 to determine whether or not the customer is moving in parallel toward the plurality of information displays 2 (S32). When not moving in parallel (S32: NO), it progresses to S22 of FIG.

  When moving in equilibrium with the information display 2 (S32: YES), the display selection unit 15 is positioned within the field of view calculated based on the customer's position and traveling direction, and a predetermined viewing angle and distance. The information display 2 to be selected is selected (S33). For the position of each information display 2, the registration list in the storage unit 14 is referred to.

  For the information display 2 outside the visual field range (S33: NO), the reproduction control unit 13 transmits a stop command or a quiet command, and controls the information display 2 to the stop or quiet mode (S36).

  For the information display 2 within the field of view (S33: YES), as described in the first embodiment (see FIG. 3), the content is reproduced using the reproduction order of the registration list stored in the storage unit 14. The information display 2 to be specified is specified, a reproduction command is transmitted to the specified information display 2, and a stop command or a quiet command is transmitted to the other information display 2 in the order of reproduction in the selected information display 2. The content is reproduced by only one information display 2 (S34).

  When the sensor 3 detects a plurality of customers, the display selection unit 15 selects an information display that exists in the OR set of each customer's view range, or is closest to the information display 2 group. It is also possible to determine the field of view by focusing only on customers at a distance.

  In the present embodiment described above, a plurality of information displays 2 in the vicinity range are handled as one unit, each position is managed, and the position and the traveling direction of a person are detected and calculated by the sensor 3, thereby calculating the image. The information display 2 within the field of view in which content is to be reproduced is selected. Thereby, similarly to the first embodiment, only the necessary information display 2 can be made conspicuous from the surroundings, and the unnecessary information display can be controlled to be stopped or in the quiet mode.

  Specifically, only the information display within the field of view in the direction of travel of the customer is conspicuous, and the information display 2 that has moved away or passed is set to the stop or quiet mode. Thereby, the information display which becomes relatively main can be made conspicuous from the circumference.

  In addition, in the method of attaching an proximity sensor to each information display and turning on the information display only when a person approaches, when a plurality of persons approach each other information display, a plurality of information displays in the vicinity range are turned on. However, according to the present embodiment, only one information display 2 can be conspicuous in the management as one unit.

<Third Embodiment>
In this embodiment, without providing a server, each information display senses a sound output from another nearby information display and autonomously controls the information display according to the sensing result.

  FIG. 9 is a configuration diagram of an information presentation system according to the third embodiment. The information presentation system of the present embodiment includes a plurality of information displays 2, and each information display 2 includes an audio detection unit 23, a reproduction timing determination unit 22, and a reproduction unit 21.

  The sound detection unit 23 detects a sound output from another information display 2 installed in the vicinity. The sound detection unit 23 is a sound collecting microphone, for example, and observes sound of an information display that is likely to affect the information display 2 in the vicinity range. By adjusting the sensitivity of the sound collecting microphone, it is possible to adjust how much range is handled as a group of information displays. A bandpass filter may be used so as not to sense the voices of nearby customers as much as possible. In addition, regarding BGM and environmental sound emitted from other than the information display 2 in the vicinity, sound below a certain sound pressure may be ignored and regarded as silent.

  The reproduction timing determination unit 22 determines the reproduction of the content when the audio detection unit 23 does not detect the sound output from the other information display 2 for the first predetermined time (n seconds). In addition, the reproduction timing determination unit 22 waits for the reproduction of the content until the second predetermined time (m seconds) elapses after the reproduction of the content ends. The playback unit 21 plays back content when the playback timing determination unit 22 determines playback.

  FIG. 10 is an explanatory diagram showing an overview of the processing of this embodiment. In the example shown in the figure, the information display (B) exists in the vicinity range 100 of the information display (A), and the sound detection unit 23 (sound collecting microphone) of the information display (A) outputs the sound output from the information display (B). Is detected. Further, the information display (A) exists in the vicinity range 200 of the information display (B), and the sound detection unit 23 (sound collecting microphone) of the information display (B) detects the sound output from the information display (A). .

  Then, each of the information display (A) and the information display (B) starts reproduction of the content in a silent state where the sound detection unit 23 does not detect the sound of the other information display.

  FIG. 11 is a flowchart showing processing of each information display 2 of the present embodiment.

  The voice detection unit 23 detects the sound output from the other information display 2 in the vicinity range, and sends the detection result to the reproduction timing determination unit 22 (S41). Based on the detection result, the reproduction timing determination unit 22 determines the reproduction of the content when the other information display 2 in the vicinity does not generate a sound for a certain time (n seconds) (S42: YES), and sends it to the reproduction unit 21. The reproduction of content is started (S43). Then, after the reproduction of the content (for example, one divided into several seconds to several tens of seconds) is finished, the reproduction timing determination unit 22 waits until a certain period of silence time (m seconds) elapses, and then S41. Returning to FIG. 2, the voice detection unit 23 observes surrounding sounds.

  Further, when the other information display 2 in the vicinity is generating sound (S42: NO), it waits until a certain time (x seconds) elapses, and then returns to S41, where the sound detection unit 23 detects the surrounding sound. Observe.

  N, m, and x are set in advance so as to be different in each information display 2 or randomly set in a certain time range so that the information display 2 in the neighboring range does not start reproduction at the same time.

  As a result, even if the server does not observe the entire information display 2 in an integrated manner, the voice detection unit 23 (sound collecting microphone) provided in each information display 2 observes the vicinity and thereby the plurality of information displays 2. Can be optimized.

  In the present embodiment described above, each information display 2 determines the timing at which content is to be reproduced by observing nearby sounds, and as a result, only one information display is highlighted in the vicinity range, The other information display 2 can be controlled so as not to reproduce the content.

  In addition, this invention is not limited to the said embodiment, Many deformation | transformation are possible within the range of the summary. For example, the content played by each information display 2 does not have to be a single data file, but can be seen as a spot ad, such as background, call to approach, detailed explanation by stopping, call to go home, etc. A series of video contents may be handled as a group and replaced as a series.
