[Technical Field]

[0001] The present invention relates to a printed matter, an information processing system, an antenna device, and a content presentation method. [Background technology]

[0002] Electronic tags are used in a variety of fields as a technology that enables contactless data transmission and reception. Near Field Communication (NFC) tags, used for short-distance communication, are a technology that can send and receive data via contactless IC cards or smartphones, and have been widely used for applications such as electronic payments, access control, and inventory management. These tags are characterized by the fact that information can be read or written contactlessly and instantly by the user simply bringing an NFC-compatible device close to the tag.

[0003] NFC tag technology has continued to evolve, and today it is standard equipment on mobile devices such as smartphones and tablets. This allows users to easily perform a wide range of operations using NFC-enabled devices, such as obtaining detailed product information, checking in for events, and even boarding public transportation. In this way, NFC technology has greatly improved user convenience.

[0004] A technology has been proposed that combines an NFC tag with a printed material to provide an explanation of a web service on the printed material. Patent Document 1 describes an NFC tag that stores the URL of a specific web page, and a printed material that includes an area printed with instructions for operating the web page. The purpose of this invention is to enable users to more easily perform online procedures. Specifically, by using a printed material equipped with an NFC tag, users can directly access a specific web page simply by holding their smartphone over the tag. Furthermore, by following the printed instructions, even users who are unfamiliar with smartphone operation can easily perform online procedures.

[0005] Patent document 1 discloses that if an NFC tag placement area is included between multiple pages, radio wave interference occurs, and that this radio wave interference can be prevented by sandwiching radio wave interference prevention material between the placement areas.

[0013] Hereinafter, a printed matter, an information processing system, an antenna device, and a content presentation method according to embodiments of the present invention will be described with reference to the drawings. Note that the embodiments shown below are merely examples of the present invention, and the present invention is not limited to the following embodiments, and various configurations can be adopted.

[0014] The electronic tag records predetermined data. The electronic tag receives electromagnetic waves emitted from a reading device and returns the recorded data to the reading device as a signal. The reading device can read the data recorded in the electronic tag by receiving the signal returned from the electronic tag. In this embodiment, an NFC tag is used as the electronic tag, but the present invention is not limited to this and an RFID tag or the like may also be used.

[0015] In this embodiment, the electronic tag is formed in a sheet shape and attached to a printed matter. The printed matter is a book, pamphlet, or the like, and is composed of multiple pages made of paper, film, or the like. The electronic tag attached to the printed matter records additional information corresponding to each page, and can provide useful information to the user along with the printed matter.

[0016] Fig. 1 shows a schematic diagram of an electronic tag T attached to a printed matter 1. Fig. 1 is a side view of the printed matter 1, and electronic tags T1 to T3 are attached to each of pages 11A to 11C of the printed matter 1. The pages of the printed matter are made of paper, film, etc., and are permeable to electromagnetic waves.

[0017] When a user views page 11A, the user can read the electronic tag T1 attached to page 11A. On the other hand, the electronic tag T2 attached to page 11B cannot be read because it overlaps with the electronic tag T1. Furthermore, the electronic tag T3 attached to page 11C can be read because it does not overlap with the electronic tag T1. In this case, multiple electronic tags are read, which creates the problem of making it difficult to determine which electronic tag is being read. Furthermore, there is a risk that the user will be provided with information from the electronic tag T3 that does not correspond to page 11A, which could result in a loss of convenience.

[0018] Fig. 2 shows an example of the configuration of the tag sheet 2 according to this embodiment. Fig. 2(a) shows a plan view of the tag sheet 2, and Fig. 2(b) shows a side view. The tag sheet 2 is configured by providing a sheet material 23 with an area including an electronic tag area 21 where an electronic tag is placed, and a shielding area 22.

[0019] The shielding area 22 is made of a material that shields the electromagnetic field of the electronic tag. Note that shielding refers to suppressing the electromagnetic field of the electronic tag to the extent that it cannot be read by a reader, and is not limited to reducing the transmittance of the electromagnetic field to zero. In this embodiment, the shielding area 22 is formed of a thin film of a conductive material. The shielding area 22 is made of, for example, a thin metal film such as aluminum foil, a transparent conductive film, a mesh film made of a conductive material, printed conductive paint, or the like.

[0020] Fig. 3 shows a schematic diagram of a printed matter 1 to which a tag sheet 2 has been attached. In Fig. 3, tag sheets 2A to 2C have been attached to pages 11A to 11C of the printed matter 1. Fig. 3(a) shows a side view of the printed matter 1. Fig. 3(b) is a top view of the printed matter 1 with pages 11A to 11C omitted, showing the relative positions of the tag sheets 2A to 2C.

[0021] 3(a), the shielding area 22A of the tag sheet 2A is positioned above and overlaps with the electronic tag area 21B of the tag sheet 2B. Also, the shielding area 22B of the tag sheet 2B is positioned above and overlaps with the electronic tag area 21C of the tag sheet 2C. When reading the tag sheet 2 from above the printed matter 1, the electromagnetic field of the electronic tag area 21 located below the shielding area 22 is shielded by the shielding area 22, so only one electronic tag area 21 can be read.

[0022] Specifically, on page 11A, the tag sheet 2A is on the top surface, so only the electronic tag area 21A is read. When page 11A is turned over, the tag sheet 2B becomes the top surface, and only the electronic tag area 21B is read. In this way, by arranging the electronic tag areas 21 and the shielded areas 22 alternately between pages in a stepped manner, it is possible to properly read only the individual electronic tags on a given page without interference.

[0023] 3(b), the shielding area 22 is formed so as to cover the electronic tag area 21 located behind it. In order to shield the electromagnetic field of the electronic tag located behind it, the shielding area 22 preferably has an area equal to or larger than the electronic tag area 21.

[0024] 3 shows an example in which a tag sheet 2 is attached to each page 11, but there may be pages 11 to which no tag sheet 2 is attached. Furthermore, the number of pages of the printed matter 1 is not limited.

[0025] It has been explained that by attaching multiple tag sheets 2 to multiple pages 11 of a printed matter 1, it is possible to read the information of the electronic tag corresponding to the page. However, in the printed matter 1 shown in Figure 3, the electronic tag area 21 shifts slightly in the in-plane direction each time the page 11 is turned over, so reading had to be performed above the electronic tag area 21. This posed a problem, requiring time and effort to search for the appropriate position for the reading device. It is also anticipated that there will be a need to place the reading device in the same location to perform stable reading even when the page is turned over.

[0026] The configuration and mechanism of the printed matter 1 further including the extension coil 3 will be described below with reference to Figs. 4 to 7. The extension coil 3 is made of a conductive material such as copper wire. The number of turns of the extension coil 3 is adjusted to match the frequency used for communication. For example, an NFC tag uses a frequency of 13.56 MHz.

[0027] In this embodiment, the extension coil 3 includes at least a detection coil 31. The detection coil 31 is a coil that extends the detection range of the electromagnetic field in the tag sheet 2. The extension coil 3 may further include a reading coil 32 in addition to the detection coil 31. The reading coil 32 is a coil that extends the detection range of the electromagnetic field in the reading device. By being connected to the detection coil 31, the reading coil 32 can transmit the interaction between the tag sheet 2 and the electromagnetic fields of the reading device.

[0028] Fig. 4(a) shows an example of the configuration of an extension coil 3 including a detection coil 31. Page 11 is omitted from Fig. 4(a). The detection coil 31 is arranged so that its coil surface faces the sheet surface of the tag sheet 2. The tag sheet 2 is arranged above and within the area of ​​the coil surface of the detection coil 31.

[0029] In Figure 4(a), the position and direction of the electromagnetic wave emitted by the reading device are indicated by electromagnetic wave E1. Electromagnetic wave E1 is emitted to the coil surface of the detection coil 31, and an electromagnetic field due to the induced current is generated within the coil surface of the detection coil 31. The tag sheet 2 located above the coil surface of the detection coil 31 is affected by the generated electromagnetic field and generates electromagnetic wave E2. Electromagnetic wave E2 is emitted to the coil surface of the detection coil 31, and an electromagnetic field due to the induced current is generated within the coil surface of the extension coil 3. The reading device can read the information on the electronic tag on the tag sheet 2 by receiving the electromagnetic field affected by electromagnetic wave E2.

[0030] Fig. 4(b) shows an example of the configuration of an extension coil 3 including a detection coil 31 and a reading coil 32. In Fig. 4(b), the extension coil 3 has a detection coil 31, a reading coil 32, and a connection part 33. As in the example shown in Fig. 4(a), the detection coil 31 is configured so that the tag sheet 2 is located above the coil plane, thereby realizing electromagnetic wave interaction with the electronic tag.

[0031] The reading coil 32 is electrically connected to the detection coil 31 via the connection part 33. The reading coil 32 realizes electromagnetic wave interaction with the reading device. The reading coil 32 receives electromagnetic waves E1 from the reading device, which causes an induced current to be generated in the coil. The induced current propagates through the connection part 33, generating an electromagnetic field E2 in the detection coil 31. The detection coil 31 changes the electromagnetic field E2 based on the information recorded in the electronic tag on the tag sheet 2, causing an induced current to be generated in the coil as a result. The changed induced current propagates through the connection part 33, generating an electromagnetic field in the reading coil 32. The reading device can read the information on the electronic tag on the tag sheet 2 via the electromagnetic field of the reading coil 32.

[0032] FIG. 5 shows several configuration examples of the extension coil 3 including a detection coil 31 and a read coil 32. The detection coil 31 and the read coil 32 are preferably formed in a sheet shape on the same plane. In one embodiment, the extension coil 3 including the detection coil 31 and the read coil 32 is attached to a flat plate made of paper, plastic, or the like, or is sandwiched between two flat plates. The extension coil 3 formed as a flat plate is placed on the back of the printed matter 1. The flat plate including the extension coil 3 is used as the back cover of the printed matter 1 or is inserted into the back.

[0033] In Fig. 5(a), one end of the conductor forming the detection coil 31 and the read coil 32 is configured as a connection portion 33, and the other end is open. In Fig. 5(b), both ends of the conductor forming the detection coil 31 and the read coil 32 are configured as connection portions 33. In each coil, an induced electromotive force is generated as the electromagnetic field changes, causing an induced current to flow. Even in a circuit where one end is open, an induced current will flow momentarily, so either an open or closed configuration of the end is acceptable.

[0034] In FIG. 5(c), the detection coil 31 and the read coil 32 each include a capacitor 34. The capacitor 34 works in conjunction with each coil to tune to the frequency of the electromagnetic waves emitted from the reader. The capacitance of the capacitor 34 can be adjusted according to the number of coil turns and frequency. The capacitor 34 may be provided in at least one of the detection coil 31 and the read coil 32 to be adjusted.

[0035] FIG. 6 shows an example of the arrangement of the extension coil 3 on the printed matter 1. The detection coil 31 and the reading coil 32 are formed on a flat plate 35 and are arranged on the back side of the printed matter 1. In FIG. 6, the detection coil 31 is shown as a shaded area. Multiple tag sheets 2 are arranged on the front side of the detection coil 31, but are omitted in FIG. 6. The reading coil 32 is shown as a shaded area. Reading by a reading device is performed on the front side of the reading coil 32.

[0036] 6(a), the flat plate 35 is configured to be the same size as a page of the printed matter 1. With this configuration, the printed matter 1 can be stored compactly without damaging the appearance of the printed matter 1.

[0037] 6(b), the flat plate 35 is configured to be larger than the page of the printed material 1, and is arranged so that the area including the reading coil 32 extends beyond the page. Note that, although FIG. 6(b) illustrates an example in which the area of ​​the reading coil 32 extends beyond the bottom side of the printed material 1, the arrangement is not limited to this, and the area may extend beyond the side or top side. With this configuration, it is possible to turn the page while the reading device is installed in front of the reading coil 32.

[0038] The sizes and positions of the detection coil 31 and the reading coil 32 are not limited to those shown in the illustration, but can be changed depending on the type and size of the printed matter 1 and the layout of the main text, etc.

[0039] FIG. 7 shows a side view of a printed matter 1 equipped with a tag sheet 2 and an extension coil 3. The printed matter 1 has pages 11A to 11F, and a tag sheet 2 is attached to each page. In FIG. 7, page 11A is the front side of the printed matter 1, and page 11F is the back side of the printed matter 1. The detection coil 31 is arranged further back than page 11F. The multiple tag sheets 2 are arranged so as to be within the range of the electromagnetic field generated by the detection coil 31.

[0040] The reader performs reading by transmitting and receiving electromagnetic waves above the reading coil 32. When page 11A is open, only the electronic tag area 21 attached to page 11A operates due to the electromagnetic field of the detection coil 31, while the electronic tag areas 21 attached to other pages do not operate because their electromagnetic fields are shielded by the shielding area 22 located on the front side. Similarly, when page 11B is open, only the electronic tag area 21 attached to page 11B operates due to the electromagnetic field of the detection coil 31.

[0041] In this embodiment, the tag sheet 2 and extension coil 3 function as an antenna device attached to the printed matter 1. The antenna device extends the range of the electromagnetic field of the electronic tag included in the tag sheet 2 by using the detection coil 31 and reading coil 32 included in the extension coil 3, allowing the reading device to read it. The antenna device may be configured to be detachable from the printed matter 1. Furthermore, the electronic tag may be readable and writable, and the data may be rewritten depending on the content of the printed matter 1.

[0042] <Information Processing System> In this embodiment, the information processing system includes a printed matter 1 and a terminal device. The information processing system may further include a server device capable of data communication with the terminal device. The terminal device functions as a reader that reads an electronic tag attached to the printed matter 1. The server device provides various information to the terminal device in response to a request from the terminal device.

[0043] In this embodiment, the terminal device may be a smartphone, a tablet terminal, etc. The terminal device includes, as hardware components, a control unit, a storage unit, a communication unit, an input unit, an output unit, and a short-range communication unit.

[0044] The control unit is composed of one or more processors such as a CPU (Central Processing Unit) and controls the overall processing of the terminal device by executing various programs and an OS (Operating System). The storage unit is composed of an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flash memory, and a RAM (Random Access Memory) and stores various programs and data. The communication unit is a communication interface for wireless communication, etc., and controls communication with external devices via a network.

[0045] The input unit is an input interface that accepts input operations by the user and is composed of a microphone, touch panel, etc. The output unit is composed of a display that outputs images and a speaker that outputs audio, etc. The short-range communication unit is a module that controls short-range communication with the electronic tag.

[0046] The short-range communication unit reads the electronic tag area 21 and acquires the additional information recorded in the electronic tag. The output unit can display or output audio based on the additional information. The additional information includes, for example, text data, image data, audio data, link information, etc. corresponding to the content of a page of the printed material 1. Note that the image data includes still images, videos, and two-dimensional codes such as QR Code (registered trademark) and barcodes.

[0047] The link information is data indicating the URL (Uniform Resource Locator) of a web page and the storage location of various data. Additional information (text, images, audio, etc.) corresponding to a page of the printed material 1 may be provided to the user by the linked web page. The terminal device may also download various data corresponding to the printed material 1 in advance and store it in a memory unit. The terminal device can reference the storage location indicated by the link information and output various data.

[0048] The additional information may include, for example, audio guidance reading each page, audio or text in a translated language for each page, audio or sound effects of characters speaking in a novel, etc. Furthermore, if the printed material 1 is, for example, a tourist guide pamphlet, the additional information may include coupons or advertisements that can be used at tourist spots, the URL of a reservation site, etc. The additional information is not limited to these examples and can be set according to the type of printed material 1.

[0049] 8 shows an example of the configuration of a printed material 1 provided with an installation unit 12 on which a terminal device 4 is installed. The installation unit 12 is provided by cutting out a portion of each page 11 of the printed material 1. A reading coil 32 is disposed on the rear side of the installation unit 12, and interacts with the electromagnetic field of the terminal device 4. The installation unit 12 has the terminal device 4 installed thereon, and with each page 11 open, exposes the display of the terminal device 4 on the surface.

[0050] Fig. 8(a) shows an example of the configuration of printed matter 1 in which an installation section 12 is provided at the edge of page 11. Fig. 8(b) shows an example of the configuration of printed matter 1 in which an installation section 12 is provided at the center of page 11. Each time a page 11 is turned over, the electronic tag provided on each page 11 is read, and the output of the terminal device 4, such as images and sounds, can be changed.

[0051] In this embodiment, the additional information includes content information related to the content, which includes various information such as images, sounds, videos, and even vibrations that affect the user's visual, auditory, and tactile senses.

[0052] 9 shows a schematic diagram of a content presentation method for effectively presenting content to a user in a picture book. In this embodiment, an electronic tag stores content information corresponding to a page.

[0053] FIG. 9(a) shows a schematic diagram of a printed material 1 provided with a cutout portion 111. In FIG. 9(a), a page 11 of the printed material 1 has a cutout portion 111 (installation portion 12) in which a terminal device 4 functioning as a reading device can be installed. The cutout portion 111 can be installed in one or more pages 11, so that at least a portion of the screen of the terminal device 4 can be visible as part of the page 11. In FIG. 9(a), the extension coil 3 is indicated by a dotted line and is installed on the back of the printed material 1, for example. The reading coil 32 is arranged so as to face and overlap the cutout portion 111 when the printed material 1 is closed. This allows the reading coil 32 to interact with the terminal device 4 and transmit the effect of the electromagnetic field.

[0054] FIG. 9(b) shows a schematic diagram of the operation of the terminal device 4 when the terminal device 4 is placed in the cutout portion 111 and the first page 11A is open. Here, the terminal device 4 reads the electronic tag corresponding to page 11A, acquires content information, and outputs content corresponding to the first page 11A. In FIG. 9(b), the terminal device 4 displays content related to images and videos of the scene corresponding to the first page 11A of the picture book on the screen. At this time, the terminal device 4 may also output content related to audio and vibration, or may output only content related to audio and vibration instead of images and videos.

[0055] FIG. 9(c) shows an outline of the operation of the terminal device 4 when the first page 11A has been turned over and the second page 11B has been opened. Here, the terminal device 4 reads the electronic tag corresponding to page 11B, acquires content information, and outputs content corresponding to the second page 11B. In FIG. 9(c), the terminal device 4 switches from content corresponding to the first page 11A to content corresponding to the second page 11B and displays it on the screen. In this way, the terminal device 4 can switch the content to be output by the terminal device 4 in response to the user's page turning operation.

[0056] In this embodiment, the electronic tag area 21 and the shielding area 22 may each be provided independently on the page 11. The electronic tag area 21 is formed in a sheet shape and provided on the page 11. The shielding area is formed in a sheet shape and provided on the page 11.

[0057] Fig. 10 shows an example of the configuration of a sheet 210 having an electronic tag area 21 and a sheet 220 having a shielding area 22 according to this embodiment. Fig. 10(a) shows a plan view of the sheet 210. Fig. 10(b) shows a side view of the sheet 210. Fig. 10(c) shows a plan view of the sheet 220. Fig. 10(d) shows a side view of the sheet 220.

[0058] 10(a) and (b), the sheet 210 is configured by providing an area including an electronic tag area 21 where an electronic tag is arranged on the sheet material 23. According to Fig. 10(c) and (d), the sheet 220 is configured by providing an area including a shielding area 22 on the sheet material 23. The configurations of the electronic tag area 21 and the shielding area 22 are the same as those in Fig. 2.

[0059] FIG. 11 shows a schematic diagram of a printed matter 1 to which an electronic tag area 21 and a shielded area 22 are attached. FIG. 11 shows an example in which electronic tag areas 21A to 21C (sheets 210A to 210C) are attached to pages 11A to 11C of the printed matter 1, respectively, and shielded areas 22A and 22B are attached to pages 11A and 11B. Note that the numbers of pages 11, electronic tag areas 21, and shielded areas 22 are not limited to these. FIG. 11(a) shows a side view of the printed matter 1. In FIG. 11(a), for the sake of simplicity, the pages 11A to 11C are shown spaced apart, but they may also abut.

[0060] 11(a), the shielding area 22A is located above the electronic tag area 21B, and faces and overlaps with the electronic tag area 21B when the printed matter 1 is closed. Similarly, the shielding area 22B is located above the electronic tag area 21C, and faces and overlaps with the electronic tag area 21C when the printed matter 1 is closed. When reading an electronic tag from above the surface of the printed matter 1, the electromagnetic field of the electronic tag area 21 located behind the shielding area 22 is shielded, so only one electronic tag area 21 can be read.

[0061] In the illustrated example, an electronic tag area 21A is provided on the front side of a first page 11A, and a shielded area 22A is provided on the back side of a second page. The electronic tag area 21A may be provided on either the front or back side of the first page, and the shielded area 22A may be provided on either the front or back side of the second page. The electronic tag area 21 and the shielded area 22 function as a pair, and as long as these paired electronic tag areas 21 and 22 are arranged facing each other and overlapping with zero, one, or multiple pages in between when the printed matter 1 is closed, they may be provided on either page or on either the front or back side. In the illustrated example, the pair of electronic tag area 21B and the shielded area 22A, and the pair of electronic tag area 21C and the shielded area 22B each function as a pair. Furthermore, the paired electronic tag area 21 and the shielded area 22 do not necessarily have to be provided on adjacent pages 11.

[0062] 11(b) is a top view of the printed matter 1 with page 11A open, and the configuration indicated by dotted lines shows the positional relationship of multiple shielding areas 22 provided on page 11 on the back side of page 11A. At this time, page 11A is provided with an electronic tag area 21A and a shielding area 22A, which are positioned so as not to overlap on the paper surface. When reading an electronic tag with page 11A open, for example, the electromagnetic field of electronic tag area 21B located behind shielding area 22A is shielded by shielding area 22A. Similarly, other shielding areas 22 also act to shield the electromagnetic field of electronic tag areas 21 located behind them, so only electronic tag area 21A can be read.

[0063] 11(c) is a top view of the printed matter 1 with page 11A turned over and page 11B opened, and the configuration indicated by dotted lines shows the positional relationship of multiple shielded areas 22 attached to page 11 on the back side of page 11B. By turning page 11A, the electronic tag area 21A and shielded area 22A attached to it are excluded. When reading an electronic tag with page 11B opened, for example, the electromagnetic field of electronic tag area 21C located behind shielded area 22B is shielded by shielded area 22B. Furthermore, the other shielded areas 22 also act to shield the electromagnetic field of the electronic tag area 21 located behind it, so only electronic tag area 21B can be read.

[0064] Fig. 12 shows a schematic diagram of a printed matter 1 to which an extension coil 3 has been added. Fig. 12(a) is a side view of the printed matter 1, in which the extension coil 3 is formed on a flat plate 35 such as the back cover and is arranged on the back side of the printed matter 1. An electronic tag area 21 and a shielding area 22 are arranged on each page 11 facing a detection coil 31. The electromagnetic field generated by each electronic tag area 21 is transmitted to a reading coil 32 via the detection coil 31. A reading device can read the electromagnetic field based on the electronic tag from above the reading coil 32.

[0065] 12(b) shows a perspective view of the printed matter 1 to which the extension coil 3 has been attached with the second page 11B opened. In the illustrated example, the extension coil 3 is actually located on the back side of the printed matter, but its location is shown through the page 11 by a dashed line. The electronic tag area 21B is located within the range of the detection coil 31.

[0066] Figure 12(c) shows a perspective view of the printed matter 1 with the extension coil 3 attached when the second page 11B has been turned over and the third page 11C has been opened. The electronic tag area 21C is located within the range of the detection coil 31. Before the second page 11B is turned over, the electronic tag area 21C and the shielding area 22B are arranged to face each other and overlap, so the electromagnetic field based on the electronic tag area 21C is shielded and only the electromagnetic field based on the electronic tag area 21B can be read. In contrast, when the third page 11C is opened as shown in Figure 12(c), only the electromagnetic field based on the electronic tag area 21C can be read.

[0067] FIG. 13 shows an example of the arrangement of a sheet 210 having an electronic tag area 21, a sheet 220 having a shielding area 22, and the like, relative to the printed matter 1. In FIG. FIG. 13(a) shows the printed material 1 with page 11A open. An extension coil 3 is provided on the back of the printed material 1, and in the illustrated example, the position of the extension coil 3 is shown through the page. In FIG. 13(a), the printed material 1 has a plurality of first regions R1 indicated by dotted lines and second regions R2 indicated by shaded regions. The first regions R1 and second regions R2 overlap with the regions of the extension coil 3 when the printed material 1 is closed. The positions of the first regions R1 and second regions R2 are not limited as long as they are within the regions of the extension coil 3.

[0068] The first region R1 indicates a region where the sheets 210 and 220 are arranged on any page from the front to the back of the printed material 1 when the printed material 1 is closed. In contrast, the second region R2 indicates a region where the sheets 210 and 220 are not arranged on any page from the front to the back of the printed material 1 when the printed material 1 is closed. In the first region R1, the sheets 210 and 220 are arranged, as shown in FIG. 13(b) as an example.

[0069] 13(c) is a schematic diagram of when an electronic tag is read by the terminal device 4. The terminal device 4 is placed in the second region R2 and can read the electronic tag region 21 of the sheet 210 via the extension coil 3. In this way, by providing the second region R2 where no sheet is placed, the terminal device 4 can read the electronic tag at the same position on any page of the printed matter 1.

[0070] FIG. 14 is a schematic explanatory diagram of binding of a printed material 1 to which a sheet 210 having an electronic tag area 21 and a sheet 220 having a shielding area 22 are attached. In FIG. 14, a back-attached binding method is used as an example of binding. In back-attached binding, one side of a manuscript (page) is used as a printing side on which text, pictures, photographs, etc. are printed, and the other side is used as a back-attached side. The back-attached side is pasted together with the back-attached side of another manuscript to form a book. Note that the number of manuscripts is not limited to the number shown in the example.

[0071] 14(a) shows the spine surfaces of documents 10A to 10C. Document 10A has pages 11A and 11B, document 10B has pages 11C and 11D, and document 10C has pages 11E and 11F. Sheet 220A with a shielded area 22 is attached to page 11A, and sheet 210A with an electronic tag area 21 is attached to page 11B. Sheet 220A attached to page 11A and sheet 210A attached to page 11B are arranged so as to face each other and overlap when document 10A is closed. Similarly, sheets 210 and 220 are attached to documents 10B and 10C, respectively. The areas in manuscript 10A where sheets 210A and 220A are provided, the areas in manuscript 10B where sheets 210B and 220B are provided, and the areas in manuscript 10C where sheets 210C and 220C are provided are arranged so as not to overlap when printed matter 1 is closed.

[0072] 14(b) shows a method of attaching the spines of the documents 10A to 10C. The documents 10A and 10B are attached by attaching the spine surfaces of the pages 11B and 11C together. The documents 10B and 10C are attached by attaching the spine surfaces of the pages 11D and 11E together.

[0073] FIG. 14(c) shows a side view of the spine-bound printed matter 1. In FIG. 14(c), pages 11A to 11F indicate the printed surface of each page. Sheets 210 and 220 are confined within the spine-bound surface and are bound without being exposed to the printed surface. In this way, by employing the spine-bound binding technique, the printed matter 1 can be bound while making maximum use of the printed surface.

[0074] Below, we will explain an application example of a content presentation method and content presentation system that presents content information stored in an electronic tag of printed matter 1 to a user. The content presentation system includes a printed matter 1 equipped with an electronic tag, a terminal device 4, and a server device 5. The terminal device 4 includes an author terminal 41 operated by the author of the printed matter 1 and the content information, and a user terminal 42 operated by a user who uses the printed matter 1. The terminal device 4 and the server device 5 are connected via a communication network.

[0075] The server device 5 includes, as its hardware configuration, a control unit such as a CPU, a storage unit such as an HDD, an SSD, a flash memory, or a RAM, and a communication unit that is a communication interface with the outside. The server device 5 has, as functional components, a registration unit 51 that accepts registration of information regarding the printed matter 1, content, access rights, etc., an output unit 52 that outputs content information, an authority control unit 53 that controls access rights to the content for the user terminal 42, and a history management unit 54 that controls the acquisition and output of access history for the printed matter 1 and content.

[0076] 15 shows an example of the configuration of various information stored in the memory unit of the server device 5. The memory unit stores printed matter information about the printed matter 1, content information about content provided by reading the electronic tag of the printed matter 1, electronic tag information about the electronic tag, user information about the user of the printed matter 1, and user printed matter information about the printed matter 1 used by the user. The registration unit 51 accepts registration of these various pieces of information via the terminal device 4.

[0077] According to FIG. 15(a), the printed matter information includes a printed matter ID, a printed matter name, the number of pages, the number of contents, the number of authority levels, and advertising permission. As shown in FIG. 15(b), the content information includes a page ID and contents C1 to C4. The content information includes zero, one, or multiple pieces of content provided by reading an electronic tag attached to each page of the printed matter 1. The number of pieces of content included in the content information is not limited to four as shown in the example. The content includes images, audio, video, and various data that act on the user's visual, auditory, and tactile senses through vibrations, etc. Print information and content information can be registered via the author terminal 41.

[0078] In this embodiment, an authority level is set for each of the contents C1 to C4. The authority level indicates the level of authority a user has to access the content. A user acquires a user authority level for each printed material 1 or for each piece of content. The user authority level is initially set to authority level 0, and is changed to authority level 1 or authority level 2, for example, depending on the amount charged. In other words, content for which an authority level has been set is only permitted to be accessed by users with a user authority level equal to or higher than that level.

[0079] According to FIG. 15(c), the electronic tag information has an electronic tag ID, a password, and a page ID. In contrast, the electronic tag mounted on the printed matter 1 stores at least the electronic tag ID and the password. In the process of attaching an electronic tag to each page of the printed matter 1, the password is written to the electronic tag. Once the password is written to the electronic tag, the server device 5 accepts registration of electronic tag information including the electronic tag ID of the electronic tag, the written password, and the page ID corresponding to the page to which the electronic tag is attached, and stores the information in the memory unit. Therefore, the user terminal 42 can obtain content information linked to the electronic tag information by reading the electronic tag.

[0080] The electronic tag may further include content data. Here, the content data may be data such as an image of the content itself, as well as link information for accessing the content. The electronic tag can allow content data to be written via a user terminal 42 that has been authorized by password authentication.

[0081] 15(d), the user information includes a user ID, a login password, etc. The user terminal 42 can access the content presentation system provided by the server device 5 using the user ID and the login password. As shown in FIG. 15(e), the user printed matter information includes a printed matter ID and a user authority level. The user printed matter information is linked to the user information and includes information about the printed matter 1 for which the user receives content via the user terminal 42. In this embodiment, the user authority level is set for each printed matter 1 used by the user, and functions as access authority to the content of the printed matter 1 for which an authority level equal to or lower than the user authority level is set. The user authority level may also be set for each page of the printed matter 1 or for each piece of content. The user information and user print information can be registered via the user terminal 42.

[0082] Fig. 16 shows a processing sequence diagram of the content presentation system. Fig. 16 explains the flow in which a user obtains printed matter 1 and receives content presentation using an electronic tag attached to the printed matter 1.

[0083] In step S101, the user terminal 42 transmits to the server device 5 an instruction to register the user printed matter information for the obtained printed matter 1. The registration instruction includes information that can identify the printed matter 1 and the user authority level for the printed matter 1. The user terminal 42 can set the user authority level by performing a billing process or the like to acquire the required user authority level according to the arbitrary authority level set for the printed matter 1.

[0084] In step S102, the registration unit 51 of the server device 5 stores in a storage unit the user printed matter information included in the registration instruction from the user terminal 42. When setting conditions required to acquire a user authority level, the registration unit 51 confirms that the conditions are met and then sets the user authority level of the user for the printed matter 1.

[0085] In step S103, the user terminal 42 reads the electronic tag attached to the printed matter 1. In step S104, the electronic tag attached to the printed matter 1 outputs the information stored in the electronic tag to the user terminal 42. Here, the information stored in the electronic tag includes at least an electronic tag ID and a password.

[0086] In step S105, the user terminal 42 transmits the information acquired from the electronic tag to the server device 5. The server device 5 refers to the electronic tag information, identifies the page ID corresponding to the electronic tag ID acquired from the electronic tag, and can acquire content information corresponding to the page ID. The authority control unit 53 of the server device 5 determines the content to be provided to the user terminal 42 based on the authority level of each content included in the content information and the user authority level. The authority control unit 53 determines one or more pieces of content having an authority level equal to or lower than the set user authority level.

[0087] In step S106, the output unit 52 of the server device 5 outputs the content determined by the authority control unit 53 to the user terminal 42. In step S107, the output unit of the user terminal 42 outputs the acquired content via a display, a speaker, a vibration element, etc., so that it can be presented to the user.

[0088] 16, after accepting registration of the user printed matter information (after step S102), the server device 5 may transmit content or content information corresponding to the printed matter 1 to the user terminal 42 automatically or in response to a request from the user terminal 42. The user terminal 42 stores the content or content information acquired in advance in a storage unit. The user terminal 42 may also acquire electronic tag information and printed matter information related to the target printed matter 1. When the user terminal 42 acquires the electronic tag information in step S104, it can reference the content or content information corresponding to the electronic tag ID and output the content. In this case, steps S105 and S106 can be omitted.

[0089] In this embodiment, the history management unit 54 of the server device 5 collects access histories by users to printed matter 1 and content, and stores them in a memory unit. The access history is linked to printed matter information or content information. The access history includes the number of users and the number of accesses for each printed matter 1 and each piece of content. The number of accesses means the number of times the content has been presented to a user. In response to a request from the author terminal 41, the history management unit 54 can output the access history linked to the author's printed matter information or content information to the author terminal 41. The author terminal 41 can display the access history as a history screen.

[0090] FIG. 17 is a display example of the history screen W1 displayed on the author terminal 41. 17, the history screen W1 has access history areas W10A to W10C that display the access history of three printed materials 1. The number of access history areas is not limited to three and may be more or less than this. The history screen W1 can specify a predetermined period and display the access history for the institution. The access history area W10 displays the number of accesses for each piece of content (contents C1 to C5) included in the printed material 1 using numerical values ​​and a chart. In the illustrated example, the numbers in parentheses next to the pieces of content C1 to C5 indicate the authority level. This allows the author to use the number of accesses as a reference when creating new printed material 1 or content.

[0091] <Application example 1> Application example 1 according to this embodiment will be described. Application example 1 provides a function for customizing content information stored in an electronic tag of printed matter 1 for each user. Application example 1 provides printed matter 1, a content presentation method using printed matter 1, a content presentation system including printed matter 1, and the like.

[0092] In Application Example 1, a readable and writable electronic tag is used, and the terminal device 4 can read and write content information from the electronic tag. The terminal device 4 can write any content to the electronic tag by specifying the content information. For example, the terminal device 4 connects to a server device 5 via a communication network or the like, and obtains content information from the server device 5. The server device 5 distributes content information corresponding to pages of the printed material 1, either for a fee or free of charge.

[0093] In Application Example 1, the electronic tag stores an electronic tag ID, a password, and a content memory. The content memory refers to a storage area in the electronic tag that stores content. Here, the content information includes a first content provided in the printed matter 1 in its initial state and a second content that can be changed by writing by the user. The first content may be configured to be protected from being overwritten by the user.

[0094] In Application Example 1, at least a first user who will be the owner of the printed matter 1 registers user printed matter information and is thereby permitted to write to the electronic tag attached to the printed matter 1 via the user terminal 42. The user terminal 42 reads the electronic tag to be written and acquires the information stored in the electronic tag. The user terminal 42 transmits the information acquired from the electronic tag to the server device 5. The server device 5 references the electronic tag information, identifies the page ID corresponding to the electronic tag ID acquired from the electronic tag, and acquires the content information corresponding to the page ID. The user terminal 42 acquires the content information from the server device 5 and displays a list of content that can be written to the electronic tag. The user terminal 42 can select any content from the list of content and write the content to the content memory of the electronic tag. Note that the user terminal 42 may also select any content data stored in the user terminal 42 and write the content to the content memory of the electronic tag. The user terminal 42 can write content to the electronic tag using a password acquired from the electronic tag.

[0095] A personal authority level can be set by a first user for content stored in the content memory. The personal authority level is an authority level that allows only the first user and other users authorized by the first user to access the content. For example, a user terminal 42 of a second user registers user printed matter information for a printed matter 1 loaned by the first user. At this time, the user terminal 42 of the second user can request approval of the personal authority level from the first user. By approving the approval request, the user terminal 42 of the first user can set a personal authority level in the user printed matter information of the second user.

[0096] As a specific example, when the user terminal 42 of a first user reads the electronic tag area 21, it can output second content information in accordance with the personal authority level. In contrast, when the user terminal 42 of a second user reads the same electronic tag area 21, if no personal authority level is set, it can output first content information in accordance with the user authority level of the second user. In this way, according to Application Example 1, it becomes possible to output any content for each user for the same printed matter 1, making it possible to give the printed matter 1 versatility.

[0097] <Application example 2> Application example 2 provides a function for multiple users to share content information stored in an electronic tag of printed matter 1. Application example 2 provides printed matter 1, a content presentation method using printed matter 1, a content presentation system including printed matter 1, and the like.

[0098] The content information in application example 2 includes a link to a sharing site. For example, if printed material 1 is a learning material, the sharing site will post information related to the page, such as tests, model answers, and opinions. This posted information can be information posted via each user's terminal device 4. The sharing site can also share the learner's progress and level of understanding with other learners and instructors via their terminal device 4. If printed material 1 is a tourist guidebook, the sharing site may also be capable of sharing word-of-mouth and reviews related to the page.
