Description

The present invention is a terminal device, display control method, and relates to a program.

  A technique for performing optical communication by processing time-series images (frames) captured using an image sensor is known. For example, when outdoor lighting or the like is used as a transmission device that emits light modulated with information, a camera built in the terminal device captures the transmission device and acquires information by demodulating the light received by the terminal device. (For example, refer to Patent Document 1).

  In the above-described information acquisition method, the frame speed of a camera that is generally used at present is about 30 frames / second from the viewpoint of ensuring image quality. When such a camera is used, the bit rate of optical communication for turning on / off each bit is about 15 bits / second. In order to increase the speed, for example, even if the color of light is changed by RGB color modulation, the bit rate is only about 45 bits / second, which is three times higher. At such a low bit rate, it is difficult to use the above-described optical communication for transmission of voice and image information.

  For this reason, instead of directly transmitting information by optical communication, the transmitting device emits only light modulated according to the ID of the information, and the terminal device uses the ID obtained by demodulating and decoding the received light as a server or the like. It is considered that the information corresponding to the ID is acquired from the server or the like.

JP 2006-20294 A

  However, even if the transmitting device emits light modulated according to the ID, if there are many types of information provided to the terminal device, the server can provide a large number of IDs with a large number of digits. It is necessary to prepare. Thus, when the number of digits of the ID is large, the time for optical communication for transmitting the ID becomes long. For example, if a 64-bit ID is prepared, 1800 pieces of information can be identified. However, if the bit rate at the time of information transmission is 15 bits / second, 4.2 seconds is required for optical communication of the ID. Resulting in. Actually, since information and a header for error detection are added to the transmitted information, the optical communication of ID requires a longer time, which is not practical.

The present invention has been made in view of such a problem, and even when there are many types of information to be provided to the terminal device, an information providing system, a server, It is an object to provide a terminal device, a display control method, and a program .

In order to achieve the above object, the present invention provides a generating means for generating content, a transmitting means for transmitting content generated by the generating means to an external server, and the external server receiving the transmitted information. From the identification information received by the receiving means, the display means, and the receiving means to the identification information associated with this information, the information displayed on the display means is changed with time series. modulating means for modulating, set by controlling the pre-Symbol display means based on the information that has been modulated by the modulating means, thereby notifying that the reception means receives the identification information, at the server on the display means And a first display control means for displaying the remaining time until the predetermined time .

  According to the present invention, even when there are many types of information provided to the terminal device, it is possible to reduce the time required for information acquisition by the terminal device.

The wired communication unit 308 is a LAN card, for example. The wired communication unit 308 communicates with the lighting device 100 and the mobile terminal 200 via the communication network 500.

  Next, the operation of the information providing system 1 will be described by the following first to third operations.

(First operation)
In the memory 304 in the server 300, device information as shown in FIG. 5 prepared for each lighting device 100 is stored in advance. The device information is information that associates the lighting device 100 with a tag ID corresponding to the light emitted by the lighting device 100 and the content corresponding to the tag ID. The device information includes a device ID of the corresponding lighting device 100, position information of the corresponding lighting device 100 (device position information including longitude and latitude), a tag ID transmitted by the corresponding lighting device 100, and content corresponding to the tag ID. It consists of data. In addition, when there is no tag ID which the illuminating device 100 transmits, tag ID and content are not contained in apparatus information.

  The operator of the server 300 sets new content. For example, in a state in which the display unit 307 displays a list of the lighting devices 100 and a map in which the lighting devices 100 are arranged, the operator operates the operation unit 306 to tag corresponding to new content. The lighting device 100 that emits light corresponding to the ID (the lighting device 100 that transmits the tag ID of the new content) is specified, and information on the new content (for example, a file name or URL in the file system) is specified.

  When there is an operator's operation, as shown in FIG. 5, the server 300 acquires device information of the lighting device 100 that transmits the tag ID of the new content (step S101). In step S <b> 101, the transmission device determination unit 312 in the control unit 302 reads out device information corresponding to the illumination device 100 designated by the worker from the memory 304.

  Next, the server 300 specifies a tag ID transmitted by another lighting device 100 that is a predetermined distance or more away from the lighting device 100 corresponding to the device information acquired in step S101 (step S102). In step S102, the transmission device determination unit 312 in the control unit 302 extracts device position information in the device information acquired in step S101. Next, the transmission device determination unit 312 extracts device position information in the device information of the other lighting devices 100. Further, the transmission device determination unit 312 calculates the distance between the positions indicated by the two pieces of extracted device position information. When the calculated distance is greater than or equal to a predetermined distance (for example, 200 m or more), the transmission device determination unit 312 acquires the tag ID in the device information of the other lighting device 100. The acquired tag ID is a tag ID transmitted by another lighting device 100 that is separated from the lighting device 100 by a predetermined distance or more.

  Next, the server 300 assigns the tag ID specified in step S102 to the new content (step S103). In step S103, the storage processing unit 314 in the control unit 302 adds, to the device information acquired in step S101, the new ID acquired based on the tag ID specified in step S102 and the new content information specified by the operator. The content data is stored in the memory 304 in association with each other.

  Next, the operation of the information providing system shown in FIG. 7 is performed. The server 300 transmits the tag ID. The lighting device 100 receives the tag ID (step S200). In step S <b> 200, the control unit 302 of the server 300 reads device information from the memory 304. Next, the control unit 302 determines that the transmission destination of the tag ID in the device information is the lighting device 100 corresponding to the device ID in the device information. Further, the control unit 302 outputs the tag ID to the wired communication unit 308 and outputs an IP (Internet protocol) address and a MAC (Media Access Control) address corresponding to the lighting device 100 to the wired communication unit 308. The wired communication unit 308 transmits the tag ID with the IP address and MAC address corresponding to the lighting device 100 as destinations. The wired communication unit 107 in the lighting device 100 receives a tag ID whose destination is an IP address or a MAC address corresponding to the lighting device 100, and outputs the tag ID to the control unit 102.

  Next, the lighting device 100 emits light (tag ID light) that is modulated according to the tag ID and that changes in luminance with time (tag ID light). In step S <b> 201, the control unit 102 in the lighting apparatus 100 outputs a tag ID that is digital data to the encoding / modulating unit 110. The encoding / modulating unit 110 encodes the tag ID output from the control unit 102 to generate a bit data string and performs digital modulation based on the bit data string. The driving unit 112 generates a driving signal corresponding to the signal output from the encoding / modulating unit 110 and for temporally changing the luminance of the light emitted from the transmitting unit 114. The transmission unit 114 emits tag ID light, which is light whose luminance changes with time, according to the drive signal output from the drive unit 112.

  For example, the user 400 sees information that is displayed on the lighting device 100 and informs that information useful for the user 400 such as coupon information as content can be acquired by photographing the lighting device 100. The lighting device 100 is photographed. At this time, the mobile terminal 200 performs acquisition and inquiry processing of the tag ID (step S202). As shown in FIG. 8, the portable terminal 200 receives light from the illumination device 100 (step S211).

  In step S211, the imaging unit 214 in the portable terminal 200 captures an optical image including the tag ID light that has entered through the lens 212, converts the image signal within the imaging field angle into digital data, and converts the frame into a frame. Is generated. In addition, the imaging unit 214 performs imaging and frame generation continuously in time, outputs continuous frames to the image processing unit 216, and sequentially stores and updates them in the buffer 218.

  Next, the mobile terminal 200 determines whether or not the tag ID has been received (step S212). In step S212, when the same coordinate in each of a predetermined amount of frames is a blinking location, the imaging unit 214 in the mobile terminal 200 determines between the coordinates of the blinking location (bright spot coordinates) and a predetermined amount of frames in the bright spot coordinates. Are stored in the coordinate data list configured in the buffer 218 and updated. Further, the decoding processing unit 220 decodes the bit data string indicating the luminance change mode stored in the coordinate data list in the buffer 218, and outputs the decoded data to the control unit 202. The identification information acquisition unit 232 in the control unit 202 determines that the tag ID has been received when the decrypted data is in the tag ID format.

  When the tag ID has not been received (step S212; NO), the series of operations ends. On the other hand, when the tag ID is received (step S212; YES), the mobile terminal 200 acquires its current position and shooting direction (step S213). In step S213, the GPS receiver 222 in the mobile terminal 200 measures the current position (latitude and longitude) of the mobile terminal 200 based on a signal from a GPS satellite and outputs the current position (latitude and longitude) to the control unit 202. The direction sensor 224 detects a shooting direction by the imaging unit 214 based on a change in geomagnetism and outputs the detected direction to the control unit 202. Here, when the illumination device 100 is included in the imaging range of the imaging unit 214, the imaging orientation by the imaging unit 214 indicates the orientation from the mobile terminal 200 to the illumination device 100. The position information acquisition unit 234 in the control unit 202 acquires the position information of the mobile terminal 200 and the shooting direction by the imaging unit 214.

  Next, the mobile terminal 200 generates inquiry information (step S214). In step S214, the control unit 202, as shown in FIG. 9, the terminal ID that is identification information of the mobile terminal 200, the acquired location information of the mobile terminal 200, the shooting orientation of the mobile terminal 200, and the acquired tag Inquiry information including the ID is generated.

  Next, the portable terminal 200 transmits inquiry information (step S215). In step S <b> 215, the control unit 202 in the portable terminal 200 outputs inquiry information to the wireless communication unit 208, and outputs an IP address and a MAC address corresponding to the server 300 to the wireless communication unit 208. Here, the IP address and MAC address corresponding to the server 300 may be stored in the memory 204 in advance, or may be transmitted from the lighting apparatus 100 together with the tag ID. The wireless communication unit 208 encodes and modulates inquiry information destined for the IP address and MAC address corresponding to the server 300 and transmits a wireless signal via the antenna 210.

  Next, the mobile terminal 200 performs content presence display and inquiry display (step S216). In step S <b> 216, the control unit 202 in the portable terminal 200 notifies an image for notifying that content as provided information exists and an image for notifying that an inquiry for acquiring the content is being performed. Are output to the display unit 207. The display unit 207 displays an image according to the image signal.

  Again, returning to FIG. The server 300 receives the inquiry information (step S203), and performs information provision processing (step S204). As shown in FIG. 10, the server 300 receives inquiry information from the mobile terminal 200 (step S221). In step S <b> 221, the wired communication unit 308 in the mobile terminal 200 receives inquiry information destined for the IP address and MAC address corresponding to the server 300 and outputs the inquiry information to the control unit 302.

  The server 300 determines a search area based on the position information and the shooting direction in the received inquiry information (step S222). In step S222, the provided information determination unit 316 in the control unit 302 determines, as a search region, a region that includes the position of the mobile terminal 200 indicated by the position information and whose direction indicated by the shooting direction is the longitudinal direction. For example, as shown in FIG. 11A, the provided information determination unit 316 has a circular area 702 centered on the position 701 of the mobile terminal 200 and the direction indicated by the terminal orientation information from the position 701 of the mobile terminal 200. A trapezoidal region 704 that is a direction indicated by an arrow 703, the direction being a longitudinal direction of a predetermined length (for example, 200 m), and extending in a direction perpendicular to the direction indicated by the arrow 703 with the direction indicated by the arrow 703 as a center. The combined area may be determined as the search area. Alternatively, as shown in FIG. 11B, the provided information determination unit 316 uses the position 701 of the mobile terminal 200 as one focal point, and the direction indicated by the terminal orientation information goes from one focal point 701 to the other focal point 702. An elliptical area that is a direction and has a predetermined distance (for example, 200 m) between the focal points may be determined as the search area. The provided information determination unit 316 generates search area information including a set of information on the position of the outer edge of the search area.

  Next, the server 300 selects one tag ID in the received inquiry information (step S223). In step S223, the provided information determination unit 316 in the control unit 302 selects one unselected tag ID among the tag IDs in the inquiry information.

  Next, the server 300 identifies device information of the lighting device 100 that is the device information including the selected tag ID and exists in the search area and is closest to the mobile terminal 200 (step S224). In step S224, the provided information determination unit 316 in the control unit 302 extracts device information including the selected tag ID from the device information stored in the memory 304. Next, the provided information determination unit 316 identifies, among the extracted device information, device information whose position indicated by the device position information is within the search area. Further, the provided information determination unit 316 specifies device information in which the position indicated by the device position information is closest to the position indicated by the terminal position information among the specified device information.

  Next, the server 300 generates result list information (step S225). In step S225, the provided information determination unit 316 in the control unit 302 corresponds to the tag ID selected in step S223 among the tag IDs in the device information specified in step S224 and the tag ID, as shown in FIG. Result list information including content data to be generated.

  Next, the server 300 determines whether or not all tag IDs in the inquiry information have been selected (step S226). In step S226, the provided information determination unit 316 in the control unit 302 determines whether there is a tag ID that is not selected in step S223 among the tag IDs included in the inquiry information received in step S221. When there is an unselected tag ID (step S226; NO), the operations after step S223 are repeated.

  On the other hand, when all the tag IDs in the inquiry information are selected (step S226; YES), the server 300 transmits the result list information (step S227). In step S227, the provided information determination unit 316 in the control unit 302 outputs the generated result list information to the wired communication unit 308, and the IP address corresponding to the mobile terminal 200 that is the transmission source of the inquiry information received in step S221. And the MAC address and the like are output to the wired communication unit 308. Here, the IP address, the MAC address, and the like corresponding to the mobile terminal 200 are information included as a source of inquiry information. The wired communication unit 308 outputs the result list information destined for the IP address and MAC address corresponding to the mobile terminal 200 to the communication network 500.

  Again, returning to FIG. The portable terminal 200 receives the result list information (Step S205). In step S <b> 205, the wireless communication unit 208 in the mobile terminal 200 receives a wireless signal via the antenna 210. Next, the wireless communication unit 208 demodulates and decodes the received signal and acquires result list information. Further, the wireless communication unit 208 outputs the result list information to the control unit 202.

  Next, the mobile terminal 200 displays content (step S206). In step S206, the control unit 202 in the portable terminal 200 extracts the tag ID in the input result list information and the content data corresponding to the tag ID. Next, in a state where the image captured by the imaging unit 214 is displayed on the display unit 207, the control unit 202 transmits the extracted tag ID among the illumination devices 100 included in the image. Determine the position in the image. Further, the control unit 202 performs processing for displaying the content data in a superimposed manner at the determined position in the image. For such processing, for example, a technique disclosed in Japanese Patent Laid-Open No. 2009-87176 is employed.

  In the first operation, when new content is generated, the server 300 sets the tag ID assigned to the content to another lighting device that is separated from the lighting device 100 that emits light corresponding to the tag ID by a predetermined distance or more. A tag ID corresponding to the light emitted by 100 is set. That is, since the illumination device 100 that emits light corresponding to the same tag ID is disposed at a position that is a predetermined distance or more away, the mobile terminal 200 receives light corresponding to the same tag ID from a plurality of illumination devices 100. Therefore, it is possible to prevent the content from being uniquely determined. For this reason, the number of tag IDs and the number of digits can be reduced, and the optical communication time for transmitting the tag ID can be shortened.

(Second operation)
In the second operation, the configuration of the device information and a part of the operation of setting the tag ID by the server 300 are different from the first operation. In the memory 304 in the server 300, device information as shown in FIG. 13 prepared for each lighting device 100 is stored in advance. The device information includes the device ID of the corresponding lighting device 100, the position information of the corresponding lighting device 100, the range information indicating the reach of light emitted by the corresponding lighting device 100, the tag ID transmitted by the corresponding lighting device 100, It consists of content data corresponding to the tag ID. The reachable range information is a set of information on the position of the outer edge of the reachable range. In addition, when there is no tag ID which the illuminating device 100 transmits, tag ID and content are not contained in apparatus information.

  The operator of the server 300 sets new content. Similar to the first operation, for example, in a state where the display unit 307 displays a list of the lighting devices 100 and a map in which the lighting devices 100 are arranged, the operator operates the operation unit 306 to The lighting device 100 that emits light corresponding to the tag ID corresponding to the new content is specified, and information on the new content is specified.

  When the operator performs an operation, as illustrated in FIG. 14, the server 300 acquires device information of the lighting device 100 that transmits the tag ID of the new content (step S <b> 301). In step S <b> 101, the transmission device determination unit 312 in the control unit 302 reads out device information corresponding to the illumination device 100 designated by the worker from the memory 304.

  Next, the server 300 specifies a tag ID transmitted by another lighting device 100 that does not overlap the light reachable range with the lighting device 100 corresponding to the device information acquired in step S301 (step S302). In step S302, the transmission device determination unit 312 in the control unit 302 extracts device reachability information in the device information acquired in step S101. Next, the transmission device determination unit 312 extracts reachable range information in the device information of the other lighting devices 100. Furthermore, the transmission device determination unit 312 identifies the two light reachable ranges indicated by the extracted two reachable range information. Next, the transmission device determination unit 312 determines whether or not the two light arrival ranges overlap. When the reach ranges of the two lights do not overlap, the transmission device determination unit 312 acquires the tag ID in the device information of the other lighting devices 100. The acquired tag ID is a tag ID transmitted by another lighting device 100 in which the light reachable range does not overlap with the lighting device 100.

  Next, the server 300 assigns the tag ID specified in step S104 to the new content (step S303). In step S303, the storage processing unit 314 in the control unit 302 adds the new device information acquired in step S301 based on the tag ID specified in step S302 and the new content information specified by the operator. The content data is stored in the memory 304 in association with each other.

  In the second operation, when new content is generated, the server 300 overlaps the range of light between the tag ID assigned to the content and the lighting device 100 that emits light corresponding to the tag ID. It is set as tag ID corresponding to the light emitted by the other illuminating device 100 which does not. That is, since the illumination device 100 that emits light corresponding to the same tag ID is disposed at a position where the light arrival ranges do not overlap each other, the mobile terminal 200 emits light corresponding to the same tag ID from the plurality of illumination devices 100. And the content is prevented from being uniquely determined. For this reason, the number of tag IDs and the number of digits can be reduced, and the optical communication time for transmitting the tag ID can be shortened.

(Third operation)
In the third operation, a case where the mobile terminal 200 receives light corresponding to the same tag ID from a plurality of lighting devices 100 will be described. In the third operation, the mobile terminal 200 generates inquiry information different from the first operation and the second operation, and transmits the inquiry information to the server 300. Specifically, as illustrated in FIG. 15, the control unit 202 of the mobile terminal 200 includes a terminal ID that is identification information of the mobile terminal 200, information on the acquired latitude and longitude of the mobile terminal 200 (terminal position information), And the direction information (terminal direction information) from the portable terminal 200 to the illumination device 100, the acquired tag ID, and the position (light reception) that receives light corresponding to the tag ID in the light receiving surface 215 of the imaging unit 214 Inquiry information including (location information) is generated. The light receiving position information is composed of a set of X and Y coordinates of the light receiving position when the light receiving surface 215 is an XY plane. The light receiving position information acquisition unit 236 in the control unit 202 monitors the light receiving position of the light corresponding to the tag ID on the light receiving surface 215 and generates light receiving position information corresponding to the light receiving position.

  The mobile terminal 200 transmits the generated inquiry information. The server 300 receives the inquiry information and performs information provision processing. As shown in FIG. 16, the server 300 receives inquiry information from the mobile terminal 200 (step S321). The specific operation is the same as that in step S221 in FIG.

  The server 300 determines whether or not there is a duplicate tag ID (duplicate tag ID) in the received inquiry information (step S322). In step S322, when the inquiry information includes a plurality of the same tag IDs, the provision / division determination unit 316 in the control unit 302 determines the tag IDs as duplicate tag IDs.

  When the duplicate tag ID exists (step S322; YES), the server 300 selects one duplicate tag ID (step S323). In step S323, the provided information determination unit 316 in the control unit 302 selects one unselected duplicate tag ID among the duplicate tag IDs in the inquiry information.

  Next, the server 300 specifies device information including the selected duplication tag ID and device information of the lighting device 100 that has emitted light received by the mobile terminal 200 (step S324). In step S324, the provided information determination unit 316 in the control unit 302 extracts device information including the selected duplicate tag ID from the device information stored in the memory 304. Next, the provided information determination unit 316 determines the imaging range in the real space by the imaging unit 214 in the terminal device 200 based on the terminal position information and the terminal orientation information in the inquiry information. Thereby, the position in the light-receiving surface 215 and the position in real space are matched. Further, the provided information determination unit 316 determines the position in the light receiving surface 215 by comparing the position (light receiving position) indicated by the light receiving position information in the inquiry information and the position in the real space indicated by the apparatus position information in the extracted device information. Are matched with the corresponding positions in the real space. When the light receiving position in the light receiving surface 215 indicated by the light receiving position information is associated with the position in the real space indicated by the apparatus position information, the provided information determination unit 316 sets the position in the real space indicated by the apparatus position information. The existing illumination device 100 is determined to be the illumination device 100 that emits light received at the light receiving position in the light receiving surface 215 indicated by the light receiving position information, and device information including the device position information is specified.

  For example, as shown in FIG. 17A, the light receiving positions indicated by the light receiving position information corresponding to the duplicate tag ID are the light receiving positions 750 (X1, Y1) and the light receiving positions 751 (X2, Y2). B), positions 711 and 712 in the real space of the lighting device 100 that emits light corresponding to the position 701 of the mobile terminal 200, the orientation 703 in the shooting direction by the imaging unit 214 in the mobile terminal 200, and the overlapping ID. And 713 are specified. In this case, the provided information determination unit 316 associates the light receiving position 750 (X1, Y1) with the position 711 in the real space of the lighting device 100, thereby causing the light corresponding to the light receiving position 750 (X1, Y1) to be emitted. It is determined that the lighting device 100 existing at the position 711 is emitted. The provided information determination unit 316 positions the light corresponding to the light receiving position 751 (X2, Y2) by associating the light receiving position 751 (X2, Y2) with the position 712 in the real space of the lighting device 100. It is determined that the lighting device 100 existing at 712 is emitted. In addition, when the information on the altitude of the lighting device 100 is included in the device position information in the device information, the provided information determination unit 316 associates the light receiving position with the altitude so that the mobile terminal 200 can more accurately It becomes possible to specify the device information of the illumination device 100 that has emitted the received light.

  Next, the server 300 generates result list information (step S325). In step S325, as shown in FIG. 18, the provision information determination unit 316 in the control unit 302 sets the tag ID selected in step S323, the light receiving position information about the light corresponding to the tag ID, and the tag ID. Result list information including corresponding content data is generated.

  Next, the server 300 determines whether or not all duplicate tag IDs in the inquiry information have been selected (step S326). In step S326, the provided information determination unit 316 in the control unit 302 determines whether or not there is a duplicate tag ID that is not selected in step S323 among the duplicate tag IDs included in the inquiry information received in step S321. To do. If there is an unselected duplicate tag ID (step S326; NO), the operations after step S323 are repeated.

  On the other hand, when there is no duplicate tag ID (step S322; NO) and when all duplicate tag IDs in the inquiry information are selected (step S326; YES), the server 300 determines the remaining tag IDs. Is performed (step S327). The processing for the remaining tag IDs is processing corresponding to the operation shown in FIG. Further, even when there is no duplicate tag ID in the inquiry information, processing corresponding to the operation shown in FIG. 10 is performed thereafter.

  In the third operation, when the mobile terminal 200 receives light corresponding to the same tag ID from the plurality of lighting devices 100, the light receiving position information on the light receiving surface 215 is notified to the server 30. On the other hand, the server 300 can specify a plurality of lighting devices 100 that emit light corresponding to the same tag ID based on the light receiving position information, and also carry data of different contents with the same tag ID. It can be transmitted to the terminal 200. For this reason, the number of tag IDs and the number of digits can be reduced, and the optical communication time for transmitting the tag ID can be shortened.

(Second embodiment)
Next, an information providing system and an information providing method according to the second embodiment of the present invention will be described with reference to the drawings. In the embodiment, the mobile terminals 200-1 to 200-2 (or the mobile terminals 200-3 to 200-4) perform information transmission by modulation with color change without using the modulated light from the lighting device 100. Explain the case. In the following description, the same reference numerals are assigned to the same components as those in the first embodiment, and the description thereof is omitted.

  As illustrated in FIG. 19, the information providing system 101 does not include the illumination device 100, and includes a mobile terminal 200 as a terminal device and a server 300.

  The mobile terminal 200 not only performs the same operation as in the first embodiment, but also functions as a lighting device (transmission device). More specifically, the display unit 207 included in the configuration of the mobile terminal 200 functions as the transmission unit 114 in the first embodiment. That is, the mobile terminal 200 directs the display unit 207 to the mobile terminal 200 of the transmission partner, and the user profile data replaced with the tag ID as the content by the marker display by the modulation accompanied with the wavelength (color) change in time series. Or send a text message or image (CG).

  Server 300 communicates with mobile terminal 200 via communication network 500 and wireless base station 600. The server 300 manages the content (the user's own profile data, text message, and image transmitted by the user 400 by operating the mobile terminal 200) and the tag ID, and corresponds to the tag ID transmitted from the mobile terminal 200. The content is transmitted to the mobile terminal 200.

  In the embodiment, the basic configuration of the mobile terminal 200 is the same as that of the first embodiment. However, in the present embodiment, the control unit 202 further functions partly as the control unit 102 of the first embodiment. The memory 204 stores a part of the program stored in the memory 104 of the first embodiment.

  The operation unit 206 includes a numeric keypad, function keys, a transparent touch panel mounted on the display surface of the display unit 207 in this embodiment, and the like, and is an interface used to input user operation details. . The display unit 207 includes, for example, an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), an EL (Electroluminescence) display, and the like. The display unit 207 displays an image (for example, a through image described later) in color according to the image signal output from the control unit 202.

  The display unit 207 incorporates a driver, and this driver functions as the encoding / modulation unit 11 in the first embodiment. This encoding / modulation mechanism is described in Japanese Patent Application Nos. 2011-139213 and 2011-139233 filed by the applicant. Specifically, the tag ID to be transmitted is designated by a color that changes in multiple colors over time, and the tag ID is transmitted by expressing this color change with a marker displayed on the display unit 207.

  Next, the operation of the information providing system 101 will be described.

  In the memory 304 in the server 300, instead of the device information as shown in FIG. 5 of the first embodiment, the entire area on the ground is divided into a grid, and this divided unit is divided into one unit. A unique region code is assigned to each table, and a table in which 64 to 128 tag IDs (up to 7 bits excluding the header code) are assigned in advance for each region code is stored. A content is assigned to the tag ID for a predetermined time based on information transmitted from the mobile terminal 200 described later.

  Referring to the flowchart of FIG. 20, the user 400 sets new content to be transmitted to the other party. This content setting operation is realized by the control unit 202 executing a program for creating and setting the content stored in the memory 204. The initial state of the setting operation is a state in which the display unit 207 of the mobile terminal 200 displays a menu screen as illustrated in FIG. 21 (step S401). In FIG. 21, characters “MENU”, characters “Take Photo”, and a camera icon 2071 are displayed on the display unit 207.

  When it is detected that the finger of the user 400 has touched the camera icon 2071 through the touch panel 206 as the operation unit 206 mounted on the display surface of the display unit 207, the mobile terminal 200 activates the imaging unit 214. Then, a process of receiving the tag ID transmitted with the time-series change of the emission color is executed. In addition, characters “Sendings” and icons 2072 to 2075 symbolizing the content to be transmitted are displayed below the characters. When it is detected through the touch panel 206 mounted on the display surface of the display unit 207 that the finger of the user 400 has touched each of the icons 2072 to 2075, the following processes assigned to the icons 2072 to 2075 are performed. Executed.

Icon 2072
An image (CG: computer) that is superimposed on a live view image (or an image after recording processing) sequentially captured by the imaging unit 214 in the mobile terminal 200 and superimposed on the display unit 207 of the mobile terminal 200 that has received the tag ID. A screen for selecting (graphic) as content to be transmitted is displayed.

-Icon 2073
The profile card of the user 400 as illustrated in FIG. 22 stored in advance in a predetermined memory area in the control unit 202 of the portable terminal 200 is displayed as content to be transmitted.

・ Icon 2074
A text message with a balloon that is superimposed on a live view image (or an image after recording processing) sequentially captured by the imaging unit 214 of the mobile terminal 200 and superimposed on the display unit 207 of the mobile terminal 200 that has received the tag ID. Is displayed as a content to be transmitted.

・ Icon 2075
The profile data of the user 400 stored in advance in a predetermined memory area in the control unit 202 of the portable terminal 200 is displayed.

  Then, the control unit 202 determines whether any selection operation of the camera icon 2071 and the icons 2072 to 2075 is detected based on the external operation by the user 400 in the display state of FIG. 21 (step S402). ). If the selection operation by step S402 is not detected (step S402; NO), the state where the menu screen of step S401 is displayed is maintained. On the other hand, when the selection operation by step S402 is detected (step S402; YES), the control unit 202 determines the selected icon, that is, the selected processing content (step S403).

  If it is determined that the selected icon is the camera icon 2071, the process proceeds to step S211 in FIG. However, in the present embodiment, in step S212, when there is a color change at the same coordinate in each of a predetermined amount of frames, the imaging unit 214 in the mobile terminal 200 has a color change coordinate and a coordinate at this coordinate. A bit data sequence representing a temporal color change mode between frames of a predetermined amount is stored in the coordinate data list configured in the buffer 218 and updated. Further, the decoding processing unit 220 decodes the bit data string indicating the color change mode stored in the coordinate data list in the buffer 218, and outputs the decoded data to the control unit 202. The identification information acquisition unit 232 in the control unit 202 determines that the tag ID has been received when the decrypted data is in the tag ID format (detailed processing is Japanese Patent Application No. 2011-139213 filed by the applicant). And in Japanese Patent Application No. 2011-139233.)

  On the other hand, if it is determined that the icon selected in step S403 is one of the icons 2072 to 2074, the control unit 202 determines that the selected icon, that is, the content of the transmission content is an image (icon 2072), Whether the profile card (icon 2073) or the text message (icon 2074) is determined (step S404). In step S404, when it is determined that the icon 2075 has been selected, the control unit 202 executes profile data editing processing, which is a known technique, and thus description thereof is omitted.

  If it is determined in step S404 that an image has been selected as the content of the transmission content, the control unit 202 displays the image generation screen on the display unit 207 (step S405). Then, the control unit 202 accepts an arbitrary operation by the user 400 at the operation unit 206, and generates an image (registration content) to be registered in the server 300 based on the operation content (step S406). When determining in step S404 that the profile card has been selected as the content of the transmission content, the control unit 202 displays the image generation screen on the display unit 207 (step S407).

  FIG. 22 shows a display mode of the display unit 207 in step S407. The contents of “Profile Card” (profile card) displayed on the display unit 207 in the figure are as follows.

Icon group 2076
It is an icon indicating the profile card attribute. In this embodiment, it is assumed that three patterns are prepared for “Business”, that is, for business, and three patterns for “Private”, that is, for private use. Corresponding to the inverted number in the icon group 2076, in the lower column, the selection content of the profile data of the user 400, which is the content of the content to be registered, and the display to be displayed on the mobile terminal 200 of the transmission partner The layout is displayed.

Profile data check box group 2077
This indicates the selection contents of the profile data included in the profile card of the user 400 to be registered as content, and the item that is black-inverted in the check box on the left of each item is included in the profile card. This selection is determined based on whether or not the user 400 touches the operation unit (touch panel) 206. Specifically, the check box displayed at the position where contact is detected repeatedly reverses and non-reverses every time the contact is detected, and as a result, selection / non-selection is switched. Thereby, the profile data of the user 400 included in the profile card can be easily set according to the attribute of the profile card.

-Text message icon 2078
When a simple text message is included together with a profile card as content, the icon is an icon that allows a simple message to be input by detecting an operation (touch).

Display layout image 2079
The mobile terminal 200 on the receiving side that receives the change in light displayed on the display unit 207 of the mobile terminal 200 on the transmitting side and decodes it to the corresponding tag ID transmits the tag ID and its own location information to the server 300. Thus, the content displayed based on the content of the response returned from the server 300 is shown. However, the content displayed in the display layout image 2079 is obtained by simplifying the actual display content and reducing the resolution, and only “what content is displayed on the mobile terminal 200 on the other side”. This is to enable confirmation.

・ SNS check box group 2080
This indicates the selection contents of the SNS (Social Network Service) to which the user 400 registered as the content belongs, and the profile card includes an item that is black-reversed in the check box on the left of each item. This selection is also determined based on whether or not the user 400 touches the operation unit (touch panel) 206. Specifically, the check box displayed at the position where contact is detected repeatedly reverses and non-reverses every time the contact is detected, and as a result, selection / non-selection is switched. Thereby, the SNS to which the user 400 included in the profile card belongs (specifically, the URL of the user page in the SNS) can be easily set according to the attribute of the profile card.

  An arbitrary operation by the user 400 on such a display screen is accepted by the operation unit 206, and the control unit 202 generates an image (registration content) to be registered in the server 300 based on the operation content (step S408). Further, when it is determined in step S404 that the message has been selected as the content of the transmission content, the control unit 202 displays the image generation screen on the display unit 207 (step S409).

  FIG. 23 shows a display mode of the display unit 207 in step S409. The contents of “Text Message” (text message) displayed on the display unit 207 in FIG.

・ Message input form 2081
This is an input field for inputting an arbitrary message.
・ History display field 2082
Messages that have been input and created in the past and registered in the server 300 are displayed. In the case where past / input messages are displayed as a history, it is assumed that the history is stored in the memory 204 of the mobile terminal 200. On the other hand, when displaying a message registered in the server 300 in the past as a history, the control unit 202 transmits a message registered in the past to the server 300 and managed as a history before displaying this screen. Request.

・ Standard message display field 2083
Display several patterns of messages prepared by default. This message may be written in advance in this program, or may be prepared on the server 300 side.
-Balloon pattern display field 2084
The input / created message is displayed on a live view image (or recorded image) as a balloon-like balloon pattern (CG) expressing “speech” or “thought” in a comic or the like according to the preference of the user 400 and superimposed on it. Can be displayed on the other party's mobile terminal. In this display field, several types of balloon patterns are displayed and determined by the user 400 selection operation.

-Text color selection field 2085
The display color of the input / created message can be changed according to the preference of the user 400. In this display field, the color pattern is displayed in several colors, and is determined by the selection operation of the user 400.

  The operation unit 206 accepts an arbitrary operation by the user 400 on such a display screen, and the control unit 202 generates an image (registration content) to be registered in the server 300 based on the operation content (step S410). Thereafter, the control unit 202 determines whether or not the creation of the selected content is completed and an instruction to execute registration to the server 300 is detected (step S411).

  If the creation of the selected content has not been completed and the registration execution instruction to the server 300 has not been detected (step S411; NO), the process returns to step S404. On the other hand, when the creation of the selected content is completed and an instruction to execute registration to the server 300 is detected (step S411; YES), the control unit 202 activates the GPS receiver 222, and the portable terminal 200 position information is acquired. Then, the control unit 202 newly adds the position information, the terminal ID that is unique ID information for identifying the mobile terminal 200 of the mobile terminal 200 from the other mobile terminal 200, and the content transmitted from the mobile terminal 200 to the server 300. Registration request command indicating that registration is requested, and device information including the contents input / created in steps S405 to 410 are transmitted to the server 300 (step S412), and the registration is successful. It shifts to the reception waiting state for receiving the result or not (step S413).

  Here, the process of the server 300 that has received the content transmitted by the process of step S412 will be described. The processing of the server 300 is substantially the same as the tag ID setting operation (FIGS. 6 and 14) in the first embodiment. In the present embodiment, processing is performed according to the procedures (steps) of steps S421 to S427 in FIG.

  As shown in the figure, the server 300 acquires device information of the mobile terminal 200 that is the transmission destination of the tag ID of the new content (step S421). Specifically, the control unit 302 detects registration request commands transmitted from the mobile terminal 200 in step S412 and included in the received device information, thereby requesting new content registration and tag ID transmission processing. Judge that it is. Next, the control unit 302 identifies the requested mobile terminal 200 by detecting the terminal ID included in the received device information. Next, the control unit 302 detects the position information of the mobile terminal included in the received device information, and determines in which region the position information is included. As a result of the determination, the control unit 302 identifies a region code corresponding to the included region (step S422).

Then, the control unit 302 determines whether or not there is a tag ID in which the corresponding content is not registered among the plurality of tag IDs assigned to the specified region code, that is, whether or not there is an empty tag ID. Is determined (step S423). As a result of this determination, if the control unit 302 determines that there is an empty tag ID (step S423; YES), the control unit 302 identifies this empty tag ID, assigns the content included in the received device information, and stores the memory The information is stored in 304 (step S425). Then, the control unit 302 transmits this tag ID to the mobile terminal 200 that is the transmission source of the device information (step S426), and starts a timer that times up in a predetermined period (for example, 10 minutes) (step S427).

  The reason for setting the predetermined period in step S427 is to prevent depletion of tag IDs due to excessive registration. However, if the number of tag IDs that can be managed with one region code is much larger than the registration request of the mobile terminal 200, the process performed in step S427 is unnecessary.

  On the other hand, if it is determined that there is no empty tag ID (step S423; NO), the control unit 302 sends the content to the mobile terminal 200 that has requested registration of the content (the mobile terminal 200 that transmitted the device information). An NG signal is transmitted assuming that there is no tag ID to be assigned (step S428).

  On the other hand, the control unit 202 in the portable terminal 200 waiting for reception in step S413 periodically determines whether or not the signal transmitted from the server 300 to itself is received (step S414). If the reception of the signal transmitted to itself is not detected (step S414; NO), the control unit 302 returns to the reception waiting state in step S413. On the other hand, when the reception of the signal transmitted to itself is detected (step S414; YES), the control unit 302 determines whether the content of the received signal is a tag ID or NG (step S415). If it is determined that the content of the received signal is a tag ID, the control unit 202 in the mobile terminal 200 that has received the received signal modulates the received tag ID to display content that changes in color over time, and converts this time series. Processing is performed so as to display the display content that changes in color on the display unit 207 (step S416).

  FIG. 24 shows a display example of the display unit 207 at this time. In the figure, a marker 2086 is a portion that is drawn in a large circle at substantially the center of the display unit 207, and this portion changes color in time series (that is, a portion that transmits a tag ID). In the same figure, the display unit 207 also displays the remaining time 2087 until the predetermined period explained in step S427 managed by the server 300 and the count cycle 2088 of one color change cycle. On the other hand, if it is determined that the content of the received signal is NG, display processing is performed to display an error on the display unit (step S417).

  Through the above-described processing, in response to the content registration request from the mobile terminal 200, the server 300 stores and manages the tag ID and the content in association with each other, while using the associated tag ID to the mobile terminal 200 that has requested registration of the content. Send. Then, the mobile terminal 200 that has received this converts the received tag ID into display content that changes color over time, and performs display processing using the display unit 207.

  Further, when the imaging unit 214 of the other mobile terminal 200 continuously captures this display content, the other mobile terminal 200 decodes this to a tag ID and transmits it to the server 300 together with its own location information. The server 300 identifies the region to which the server 300 belongs from the received position information, determines the region code, reads the content registered in association with the tag ID received in the region managed by this region code, It transmits to the other portable terminal 200.

  25 to 26 show specific usage examples. For example, in FIG. 25, when the portable terminal 200-2 executes the process in FIG. 20 and the result is the marker 2086-2 displayed on the display unit 207-2 with the profile card of the user 400-2 as content. It is a figure which shows the condition which is transmitting the tag ID corresponding to this with a serial color change. FIG. 26 is a display example of the display unit 207-1 of the portable terminal 200-1 that captures the state of FIG.

  In the figure, the upper body of the user 400-2 is displayed as a live view, and in addition to this, the configuration shown in the display layout 2079 of FIG. 22 is added. That is, the image 2089 is superimposed on the upper part of the live view screen, and the display unit 207-2 of the mobile terminal 200-2 in the upper body image of the user 400-2 (specifically, the place where the marker 2086-2 is displayed). The image 2090 is superimposed and displayed as the content registered in the server 300 corresponding to the received tag ID. The balloon 2091 displays the profile card data registered by the user 400-2 as the content registered in the server 300 corresponding to the received tag ID.
