More specifically, the antenna 3 performs wireless communication for writing information to the IC tag or performs wireless communication for reading information stored in the IC tag.
In the present embodiment, the antenna 3 is provided over the outer periphery of the housing of the display device 1. Note that the antenna 3 is not limited to being provided on the outer periphery of the casing of the display device 1, and may be provided so as to be able to communicate with an IC tag at an arbitrary position in the screen of the display device 1. For example, a plurality of antennas 3 may be provided on the screen with transparent electrodes or the like so as not to affect the display of the display device 1. Further, the installation of the antenna 3 is appropriately selected depending on the type of the selected IC tag, such as the use frequency of the IC tag and whether the IC tag is a passive type or an active type.

  Here, the IC tag will be described. The IC tag includes a CPU, a memory, and an antenna. The CPU stores the information received via the antenna in the memory, or transmits the information stored in the memory to the outside via the antenna. The memory is a nonvolatile memory and stores information received via the antenna. The antenna exchanges information with the antenna 3 of the information providing system 100. The antenna generates electricity by receiving radio waves from the antenna 3 of the information providing system 100. Therefore, the IC tag has a feature that it does not have an internal battery.

Further, the CPU 21 may be configured to also serve as the antenna control unit 4.

  The position detection device 5 detects the position of the finger or the mobile phone 8 that is close to the screen of the display device 1, that is, the shielding object (detection object) on the screen. The position detection device 5 includes a line sensor 11 and a retroreflective plate 12. Two line sensors 11 are provided on the left and right of the display device 1. The two line sensors 11 each have a light emitting part and a light receiving part. The retroreflective plate 12 is provided so as to surround the screen 7 except for one side on the side where the line sensor 11 is attached among the periphery of the screen 7 of the display device 1. Further, the line sensor 11 and the retroreflective plate 12 are attached in a state slightly separated from the top of the screen 7 of the display device 1 as shown in FIG.

  The position detection device 5 normally projects light from the light emitting unit of the line sensor 11 to the retroreflective plate 12, and the light reflected by the retroreflective plate 12 is received by the light receiving unit. Here, it is assumed that there is a shield such as a finger or a mobile phone 8 between the line sensor 11 and the retroreflective plate 12. In this case, since the position detection device 5 cannot receive the retroreflected light only in the portion where the shielding object exists, the light receiving unit can detect the presence of the shielding object in the shadow portion. Since the position detection device 5 is attached in a state slightly separated from the screen of the display device 1, the position detection device 5 is in a close proximity before the finger or the mobile phone contacts the screen 7 of the display device 1. Even it can be detected. A detailed description of the position detection device 5 is described in Patent Document 5.

Or transmitted to the CPU 21 of the information providing apparatus 2. In addition, CPU21 of the information provision apparatus 2 can calculate the position of a shield from the received detection information. More specifically, the position detection control unit 6 receives light reception information of the shielding object via the light reception units of the two line sensors 11 attached to the left and right of the display device 1. The position detection control unit 6 transmits detection information to the information providing device 2 based on the received light reception information. Based on the received detection information, the CPU 21 of the information providing device 2 calculates the intersection of the shielding objects as a coordinate value of a position close to the screen of the display device 1. Note that the calculation of the coordinate value of the shielding object on the screen of the display device 1 is not limited to this case. For example, the position detection control unit 6 itself may calculate the coordinate value of the shielding object based on the light reception information. The CPU 21 may be configured to also serve as the position detection control unit 6, and the CPU 21 may calculate the coordinate value of the shielding object directly from the light reception information.

  Here, with reference to FIG. 3, the operation | movement which the information provision system 100 performs is demonstrated easily. FIG. 3 is a diagram illustrating a schematic configuration of a part of the information providing system 100. As shown in FIG. 3, an antenna 3 and a position detection device 5 (line sensor 11 and retroreflective plate 12) are provided around the screen 7 of the display device 1. In addition, the CPU 21 of the information providing device 2 displays predetermined image data stored in the external storage device 25 on the screen 7 of the display device 1 by dividing it with a window or the like, for example. Here, the displayed image data includes, for example, image data related to contents, image data related to advertisements for new products, image data related to advertisements for restaurants, and the like. Next, the user brings the image of the window of interest out of the images displayed on the screen 7 into proximity or contact (hereinafter referred to as proximity) using a finger or the mobile phone 8.

  The position detection control unit 6 transmits detection information from the light reception information received by the position detection device 5 to the CPU 21 of the information providing device 2 via the network interface 26. The CPU 21 of the information providing apparatus 2 calculates the coordinate value of the position of a shield such as a finger or a mobile phone based on the detection information. Based on the coordinate information (position information) of the calculated coordinate value, the CPU 21 controls the screen of the display device 1 so as to switch the window corresponding to the coordinate information to a detailed screen. In some cases, the CPU 21 of the information providing apparatus 2 writes the window information corresponding to the coordinate information in the memory of the IC tag of the mobile phone 8 based on the coordinate information (position information) of the calculated coordinate value. do. Here, the information written in the memory of the IC tag includes, for example, information on contents, a URL of a home page on which a catalog of new products is posted, a coupon usable at a restaurant, and the like. Note that the processing of the CPU 21 of the information providing apparatus 2 described above is performed based on a control program stored in the external storage device 25.

  As described above, the information providing system 100 is provided so that the antenna 3 can communicate with an IC tag at an arbitrary position in the screen of the display device 1. Further, the information providing system 100 is provided with the position detection device 5 that can detect the position of the finger or the mobile phone 8 close to the screen on the display device 1 with high definition. The coordinate value can be calculated accurately. That is, the screen displayed on the display device 1 is not limited by the antenna 3 as in the prior art, and the coordinate value of the position of the finger or the mobile phone 8 can be accurately calculated, so the screen design of the display device 1 can be freely designed. Can improve the advertising effectiveness. In addition, since the user can accurately instruct the information providing apparatus 2 at the close position of the screen 7 by the finger or the mobile phone 8, the information collecting operation can be performed seamlessly.

Next, a table stored in the external storage device 25 of the information providing device 2 will be described with reference to FIG. The table shown in FIG. 4 shows a part of a screen management table (hereinafter referred to as a table) stored in the external storage device 25.
FIG. 4 is a table in which image data displayed on the display device 1, coordinate information (position information) when the image data is displayed, link information, and the like are associated with each other. In the tables 411 to 431 shown in FIGS. 4A to 4C, screen numbers 1 to 3 are assigned as identification numbers, respectively. The CPU 21 of the information providing device 2 first displays the information of the table 411 defined by the screen number 1 as an initial screen on the display device 1.

In the table 411 shown in FIG. 4A, four display areas are defined. The display areas A to D are assigned to the four display areas as identification numbers, respectively. In addition, coordinate information (position information) 413 is defined in the display areas A to D. The coordinate information 413 is composed of four coordinate values of xstart, ystart, xend, and yield. A position displayed on the screen 7 of the display device 1, that is, a rectangular area is specified by these four coordinate values.
In the table 411, a display file 414 is defined in association with the display area and coordinate information 413. The CPU 21 of the information providing apparatus 2 reads the image data specified by the file name of the display file 414 and displays it in the rectangular area specified by the coordinate information 413.

  In the table 411, a next screen number (link information) 415 is defined in association with the display area and the coordinate information 413. The next screen number 415 includes a numerical value of the screen number. This numerical value corresponds to the numerical value of the drawing number shown in FIGS. The CPU 21 of the information providing apparatus 2 compares the coordinate information of the calculated coordinate value (the position of the screen 7 that the user touches using a finger or a mobile phone) with the coordinate information 413 of the table 411, and the calculated coordinate value is Identify the included display area. Next, the CPU 21 refers to the next screen number 415 associated with the specified display area, and displays an image on the display device 1 based on a table of screen numbers specified by the next screen number 415.

  Here, with reference to FIG. 5, a case where the above-described screen transitions will be described. FIG. 5A is a diagram showing an example in which information defined by screen number 1 is displayed as an initial screen. On the screen 7 shown in FIG. 5A, four windows of display areas A to D are displayed. First, if the user brings the mobile phone 8 close to the display area A, the position detection device 5 receives light using the mobile phone 8 as a shielding object (detection object). The position detection control unit 6 transmits the detection information to the information providing device 2 based on the light reception information by the position detection device 5. The CPU 21 of the information providing apparatus 2 calculates the coordinate value of the position where the mobile phone 8 is close based on the detection information. The CPU 21 compares the coordinate information (position information) of the calculated coordinate value with the coordinate information (position information) 413 of the table 411 and determines that the display area including the calculated coordinate value is the display area A. To do. Next, since the next screen number 415 associated with the display area A is the screen number 2, the CPU 21 displays an image on the display device 1 based on the table of the screen number 2, that is, the table 421 shown in FIG. Is displayed. FIG. 5B is a diagram showing an example in which information defined by the screen number 2 is displayed.

Next, the table 421 shown in FIG. 4B will be described. In the table 421, eight display areas are defined. Display areas A1 to A8 are assigned to the eight display areas as identification numbers, respectively.
In the table 421, a transmission file 425 is defined in association with the display area and coordinate information. The CPU 21 of the information providing apparatus 2 reads information specified by the file name of the transmission file 425 and transmits it to the antenna control unit 4. The antenna control unit 4 performs processing for writing received information to the IC tag of the mobile phone 8 via the antenna 3 under the control of the CPU 21. In the table 421, the transmission file 425 is associated with the display areas A1 to A3 and A5 to A7.
In the table 421, a print file 426 is defined in association with a display area and coordinate information. The CPU 21 of the information providing apparatus 2 reads information specified by the file name of the print file 426 and transmits it to a printing apparatus (not shown). The CPU 21 controls the printing apparatus and outputs the received information. In the table 421, print files 426 are associated with display areas A2 and A6.

Here, with reference to FIG. 5B, a process of writing information to the above-described IC tag will be described. First, when the user brings the mobile phone 8 close to the display area A1, the position detection device 5 receives light using the mobile phone 8 as a shielding object (detection object). The position detection control unit 6 transmits the detection information to the information providing device 2 based on the light reception information by the position detection device 5. The CPU 21 of the information providing apparatus 2 calculates the coordinate value of the position where the mobile phone 8 is close based on the detection information. The CPU 21 of the information providing apparatus 2 compares the coordinate information (position information) of the calculated coordinate value with the coordinate information (position information) 423 of the table 421, and the display area including the calculated coordinate value is a display area. It determines with it being A1. Next, the CPU 21 reads information specified by the file name of the transmission file 425 associated with the display area A1 and transmits the information to the antenna control unit 4. The antenna control unit 4 performs processing for writing received information to the IC tag of the mobile phone 8 via the antenna 3 under the control of the CPU 21.
In FIG. 5, among the windows displayed on the display device 1, a window that transitions to a different screen when approaching is referred to as a selection window, and a window that proceeds to a process of writing information to an IC tag is referred to as an information window. . Further, the window displayed on the display device 1 does not necessarily have to be displayed so as to be recognized by the user.

  Next, a case where unintended information is written in the IC tag in the information providing system 100 described above will be described with reference to FIG. Here, it is assumed that the selection window of the display area A shown in FIG. 5A overlaps the information window of the display area A1 shown in FIG. First, when the user brings the mobile phone 8 close to the selection window of the display area A, the CPU 21 causes the display device 1 to display the screen 421 of the screen number 2 associated with the display area A as shown in FIG. An image as shown in (b) is displayed. However, when the image shown in FIG. 5B is displayed, the user may be in a state where the mobile phone 8 is kept in proximity to the information window in the display area A1. At that time, the antenna control unit may write information on the transmission file 425 associated with the display area A1 unintended by the user to the IC tag under the control of the CPU 21.

  Therefore, in the present embodiment, when the position where the mobile phone 8 is approached when the screen is changed is an information window, the antenna control unit 4 controls the mobile phone 8 via the antenna 3 under the control of the CPU 21. The IC tag is configured not to write information. As such a configuration, for example, the antenna control unit 4 turns off the power of the antenna 3 for a certain period of time under control of the CPU 21, stops the transmission of radio waves, or does not perform the information writing process. do it.

  Further, based on the detection information from the position detection control unit 6, the antenna control unit 4 may be configured not to write information under the control of the CPU 21. As such a configuration, for example, it is assumed that the CPU 21 continuously receives the detection information of the detected object from the position detection control unit 6 when the screen is changed. In this case, the antenna control unit 4 is configured not to write information to the IC tag of the mobile phone 8 via the antenna 3 under the control of the CPU 21. Then, after the CPU 21 no longer receives detection object detection information from the position detection control unit 6, the antenna control unit 4 starts providing information to the IC tag of the mobile phone 8 under the control of the CPU 21. Good.

  Even if the detection information of the detected object is continuously received from the position detection control unit 6, the antenna control unit 4 only detects and detects whether there is an IC tag to which information can be written. The control unit 4 may not write information under the control of the CPU 21. When the IC tag is not detected, the antenna control unit 4 keeps the setting under the control of the CPU 21. In this case, the antenna control unit 4 may start providing information by detecting no IC tag under the control of the CPU 21, and the position detection control unit 6 does not detect the shielding object and detects it again. After that, provision of information may be started.

  As described above, the CPU 21 of the information providing device 2 controls the antenna control unit 4 and the position detection control unit 6 based on the condition (transition condition) when the screen changes, so that information can be obtained for the non-contact IC. Can be prevented from being erroneously transmitted.

Next, a main flowchart of processing of the information providing apparatus 2 will be described with reference to FIG.
In step S <b> 401, the CPU 21 of the information providing device 2 first displays information on the table defined by the screen number 1 on the display device 1 as an initial screen.
Next, in step S402, the CPU 21 enters an input waiting state. More specifically, the CPU 21 determines whether or not the detection information of the detected object is received from the position detection control unit 6. For example, when the user uses the finger or the mobile phone 8 to approach the screen of the display device 1, the position detection control unit 6 detects the detected object via the position detection device 5 and transmits the detection information to the information providing device 2. (Detection information acquisition means). Here, the position detection control unit 6 may detect by a method unique to the position detection device 5. Depending on the specifications of the position detection device 5, the position detection control unit 6 may detect contact of the display device 1 with the screen. Further, in the case of the light shielding method as in the present embodiment, the position detection control unit 6 may transmit the detection information of the detected object when the level of the light shielding shadow is equal to or higher than a predetermined level, and the speed of the shield is increased. When the speed is equal to or lower than the predetermined speed, the detection information may be transmitted assuming that the position is selected. When the detection information of the detected object is not received, the CPU 21 continues to wait for input. When the detection information of the detected object is received, the CPU 21 advances the process to step S403.

In step S <b> 403, the CPU 21 calculates the coordinate value of the position approached on the screen of the display device 1 based on the received detection information (position information acquisition unit).
Next, in step S <b> 404, the CPU 21 compares the coordinate information (position information) of the calculated coordinate value with the coordinate information (position information) of the table of the displayed screen number and includes the calculated coordinate value in the calculated coordinate value. The display area to be displayed is determined. Next, the CPU 21 refers to the table to determine whether or not link information (next screen number) is associated with the determined display area. If the link information is associated, the CPU 21 advances the process to step S405. If the link information is not associated, the CPU 21 advances the process to step S410.

In step S <b> 410, the CPU 21 reads information on the transmission file associated with the display area and transmits the information to the antenna control unit 4. The antenna control unit 4 performs processing for writing the received information to the IC tag via the antenna 3 under the control of the CPU 21 (writing processing means).
In step S405, the CPU 21 specifies the next screen number as link information associated with the display area. The CPU 21 prepares to change the display of the display device 1 based on the next screen number table.

Next, in step S406, the CPU 21 determines a transition condition.
Here, the transition condition is, for example, determination of whether or not the coordinate value calculated by the CPU 21 based on the current detection information is an information window on the screen after the transition.
Here, determination of the transition condition will be described with reference to a flowchart shown in FIG.
First, in step S501, the CPU 21 determines whether or not the coordinate value calculated based on the current detection information is an information window on the screen after transition. If it is an information window, in step S502, the CPU 21 performs a process of setting a stop flag. On the other hand, if it is not the information window, in step S503, the CPU 21 performs a process of resetting the stop flag.
In step S504, the CPU 21 performs a process of starting a timer for a predetermined time, and returns to the main flowchart.

  In step S407, the CPU 21 determines whether information can be provided to the IC tag, that is, whether information can be written. Specifically, whether the information can be provided is determined by the CPU 21 with reference to the stop flag, based on whether the stop flag is set. When the stop flag is set, the CPU 21 advances the process to step S408 and performs setting to stop providing information. After setting to stop providing information or when the stop flag is not set, the CPU 21 advances the process to step S409. Here, the setting for stopping the provision of information is a setting not to perform the information writing process on the IC tag. For example, the antenna 3 is turned off or the transmission of radio waves is stopped. It means to do.

In step S409, the CPU 21 changes the screen and displays the screen on the display device 1 based on the next screen number table (display switching processing means).
Next, in step S411, the CPU 21 determines whether or not the provision of information can be resumed.
In step S412, the CPU 21 determines whether or not the predetermined timer has elapsed in step S504 shown in FIG. If the predetermined time has elapsed, the CPU 21 advances the process to step S413. If the predetermined time has not elapsed, the CPU 21 returns the process to step S411.
In step S413, the CPU 21 resets the stop flag and performs setting for restarting provision of information. That is, the CPU 21 reads information on the transmission file associated with the display area and transmits it to the antenna control unit 4. The antenna control unit 4 performs processing of writing received information to the IC tag via the antenna 3 under the control of the CPU 21.

Note that the determination of resuming the provision of information in step S411 is not limited to determining whether or not a predetermined time has elapsed. For example, the determination may be made based on whether or not the CPU 21 has received detection information from the position detection control unit 6. A case where provision of information is resumed based on reception of detection information will be described with reference to a flowchart of FIG. First, in step S <b> 601, the CPU 21 determines whether the detection information of the detected object is continuously received from the position detection control unit 6. When the detection information is continuously received, in step S602, the CPU 21 performs processing for setting a stop flag. On the other hand, when the detection information is not received, the CPU 21 performs a process of resetting the stop flag in step S603.
Returning to the main flowchart of FIG. 6, in step S412, the CPU 21 determines whether or not a stop flag is set. If the stop flag is set, the process proceeds to step S413. When the stop flag is not set, the CPU 21 returns the process to step S411. That is, in step S601 of the flowchart of FIG. 8, the CPU 21 continuously receives detection information of the detected object from the position detection control unit 6. It is determined whether or not.

Further, the determination of restarting the provision of information in step S411 may be performed by the CPU 21 based on whether or not there is IC tag detection information from the antenna control unit 4. A case where the provision of information is resumed based on whether there is detection information of the IC tag will be described with reference to the flowchart of FIG. First, in step S <b> 701, the CPU 21 determines whether or not IC tag detection information has been received from the antenna control unit 4. When the detection information of the IC tag is received (IC tag detection information acquisition means), in step S702, the CPU 21 performs a process of setting a stop flag. On the other hand, when the information that there is no IC tag is received, in step S703, the CPU 21 performs a process of resetting the stop flag.
Returning to the main flowchart of FIG. 6, in step S412, the CPU 21 determines whether or not a stop flag is set. If the stop flag is set, the process proceeds to step S413. When the stop flag is not set, the CPU 21 returns the process to step S411. That is, in step S701 of the flowchart of FIG. 9, the CPU 21 determines whether or not the IC tag detection information is received from the antenna control unit 4. To do. Note that the processing of the flowcharts of FIGS. 8 and 9 described above can also be applied to the processing of step S407 in FIG.

  In the present embodiment, it can be configured such that information is written to the IC tag only when the user touches the screen of the display device 1 using the mobile phone 8. However, in the present embodiment, it is not a necessary condition to contact the screen 7 of the display device 1 so that the CPU 21 can provide information by calculating the coordinate values of the positions close to the screen 7 in the vicinity. It is composed.

  Further, in the present embodiment, the flowchart shown in FIG. 6 is configured such that the screen transition cannot be performed unless the resumption of information provision is confirmed, but the present invention is not limited to this case. For example, when calculating the coordinate value of the position touching the screen, using an event-driven program, when an event such as a touch by the user occurs, the part is a screen transition May be configured to allow screen transitions. In this way, the best mode may be selected as appropriate depending on the system.

  In the present embodiment, it is determined whether or not information can be provided when the screen is changed. However, the present invention is not limited to this case. For example, it may be configured such that processing for uniformly stopping the provision of information is performed, and only the resumption condition is canceled when the detection information of the proximity to the screen 7 is once lost and close again as described above. . As described above, the uniform stop may be treated as one of the transition conditions.

(Second Embodiment)
In the first embodiment, whether or not to provide information is determined based on whether a predetermined time has elapsed, receiving detection information from the position detection control unit 6 continuously, or detecting an IC tag. Went. In the second embodiment, it is determined whether to provide information by combining these. For example, when an IC tag is close to the information window, a process for writing information such as a URL of a product or a coupon into the IC tag via the antenna 3 in a non-contact manner. On the other hand, when an information window is selected with a finger instead of an IC tag, a product catalog or a coupon is provided as a printed matter separately from a printing device or the like.

The transition of the screen according to the second embodiment will be described with reference to FIG.
Reference numeral 801 denotes a state of the screen 1 in which the CPU 21 first displays the information of the table defined by the screen number 1 as the initial screen on the display device 1. At this time, the antenna 3 is transmitting radio waves. Here, the user uses the finger or the mobile phone 8 to select a store selection window from a plurality of selection windows displayed on the screen 1.

Reference numeral 802 denotes a state of the screen 2 displayed by the CPU 21 when the user selects a store selection window using a finger (without using an IC tag). On the screen 2, the antenna control unit 4 is set in a state where information can be written to the IC tag under the control of the CPU 21. In addition, an information window of the selected store is displayed.
Reference numeral 804 denotes a state of the screen 3 displayed by the CPU 21 when the user selects a store information window from the state of the screen 2 of 802 using a finger (without using an IC tag). On the screen 3, the CPU 21 changes the output destination from the IC tag to the display device 1 and displays the store coupon (output control means). Further, the CPU 21 can print the selected information via a printing device (output control means). Note that the output destination may be at least one of the display device 1 and the printing device.

  Reference numeral 803 denotes a state of the screen 2 displayed by the CPU 21 when the user selects a store selection window using the mobile phone 8. On the screen 2 in 803, the antenna control unit 4 is set in a state where information cannot be written to the IC tag under the control of the CPU 21. From this state, when the position detection control unit 6 no longer detects the detected object, that is, when the cellular phone 8 is no longer in proximity, the antenna control unit 4 sends information to the IC tag under the control of the CPU 21. Set to a writable state.

  Reference numeral 805 denotes the state of the screen 2 when the position detection control unit 6 no longer detects the shielding object from the state of the screen 2 of 803. On the screen 2, the antenna control unit 4 is set in a state where information can be written to the IC tag under the control of the CPU 21. In the state of the screen 2 of 805, when the user again uses the mobile phone 8 to move close to the screen 2 and selects the store information window, the antenna control unit 4 performs the information writing process on the IC tag. It can be performed.

  According to the second embodiment, at the timing when the selection window or the information window is selected, the antenna control unit 4 determines whether there is an IC tag (determination means). Then, according to the determination result, if there is an IC tag, the CPU 21 performs a writing process, and if there is no IC tag, prints or displays a different screen. In this manner, equivalent information can be provided to a user who has the mobile phone 8 and a user who does not have the mobile phone 8.

(Third embodiment)
In the second embodiment, the CPU 21 switches processing to be performed next by detecting whether or not there is a non-contact IC tag. In the third embodiment, a case where processing is switched depending on the type of IC tag will be described. The IC tag is built into the IC card and used as a train ticket, or is built into the mobile phone 8 to pay for a wallet. Means for discriminating the type of IC tag (including a medium in which the IC tag is incorporated) may be provided, and the screen to be displayed and the information to be provided may be changed based on the type of the IC tag.

  For example, IC cards that can be used in convenience stores differ for each type of convenience store. It is assumed that an advertisement for a certain product is displayed on the display device 1 of the information providing system 100 and the information providing device 2 provides information such as directions to a store that can be purchased. At that time, the information providing apparatus 2 may detect the type of the IC tag brought close to the screen by the user and provide map information to a convenience store corresponding to the IC tag. As described above, according to the third embodiment, it is possible to read / write data from / to a plurality of types of IC tags, and to have a means for determining the type of IC tag. The effect is improved.

(Fourth embodiment)
In the first to third embodiments, the transition of the screen displayed on the display device 1 by the CPU 21 of the information providing device 2 by detecting whether there is an IC tag or detecting the type of the IC tag. Had changed. In the fourth embodiment, whether the finger or the mobile phone 8 detects a moving speed at which the finger or the mobile phone 8 approaches or touches the screen of the display device 1 and provides information based on whether the detected moving speed is equal to or less than a certain speed Determine whether. By detecting the moving speeds close to each other in this way, it is possible to prevent information unintended by the user from being written to the IC tag.

  Here, a case where information unintended by the user is written to the IC tag will be described with reference to FIG. FIG. 11 shows an example of the screen 7 of the display device 1 having a large screen display. The screen 7 displays an advertisement relating to “latest television”, an advertisement relating to “real estate information”, and an advertisement relating to “cosmetics”. Here, it is assumed that the user uses the mobile phone 8 to approach or touch the display area of “real estate information” that is desired information. In such a case, when the user moves the mobile phone 8, there is a possibility that the user may pass through another display area, for example, the “latest television” display area, before approaching or contacting the “real estate information” display area. As described above, when information is written in the IC tag simply by bringing the mobile phone 8 close to or in contact with the screen, information unintended by the user may be written.

  Therefore, in the fourth embodiment, when acquiring information desired by the user, the CPU 21 writes information to the IC tag on condition that the mobile phone 8 is stopped in a predetermined display area. Process. More specifically, the CPU 21 detects the moving speed based on the coordinate value and the sampling time of the position where the mobile phone 8 is close to or in contact with the screen of the display device 1. It is determined whether or not the moving speed detected by the CPU 21 is equal to or lower than a predetermined speed. If the moving speed is equal to or lower than a predetermined value (substantially stopped state), information on the display window corresponding to the coordinate value when the predetermined speed or lower is detected is IC. Write to the tag. With this configuration, even when the user selects a large-screen display, it is possible to prevent writing unintended information and provide only desired information. Note that the present invention is not limited to selecting an information window, and may be applied to selecting a selection window.

Next, processing of the information providing apparatus 2 according to the fourth embodiment will be described with reference to FIG.
In this process, a sampling period is predetermined in order to calculate the moving speed. In this embodiment, the interruption time is set to 10 [msec], for example.
First, in step S <b> 1001, the CPU 21 reads the storage device in order to obtain a coordinate value when approaching or touching the storage device (hereinafter referred to as storage device) such as the RAM 23 or a buffer.
Next, in step S1002, the CPU 21 determines whether coordinate values are stored. When the coordinate value is not stored, the CPU 21 advances the process to step S1011. If coordinate values are stored, the CPU 21 advances the processing to step S1003.

  In step S1011, the CPU 21 sets a flag indicating initial acquisition and returns from the interrupt. Next, in step S1012, the CPU 21 stores the coordinate value as no value in the storage device. Thereafter, the CPU 21 returns the process to step S1001. In step S1012, the coordinate value is not stored, but the process of step S1012 may be skipped.

In step S1003, the CPU 21 determines whether or not a flag indicating initial income is set. When the flag indicating the first income is set, the CPU 21 advances the process to step S1004. If the flag indicating the first income is not set, the CPU 21 advances the process to step S1005.
In step S1004, the CPU 21 cannot calculate the moving speed because it is the coordinate value acquired for the first time. Therefore, after clearing the flag indicating the first acquisition, the CPU 21 performs a process of returning from the interrupt. Next, in step S1012, the CPU 21 stores the coordinate value acquired for the first time in the storage device as the previous coordinate value.

In step S1005, the CPU 21 calculates a moving speed based on the coordinate value acquired in step S1001 and the previous coordinate value stored in the storage device (moving speed detecting unit). Here, the movement speed can be calculated in step S1005 because the flag indicating the first income is cleared in step S1004 and the previous coordinate value is stored in step S1012.
The moving speed Vc is calculated by assuming that the previous coordinate value is Pp (xp, yp), the acquired coordinate value is Pc (xc, yc), and the sampling time is Ts.
Vc = SQRT ((xp-xc) ^ 2 + (yp-yc) ^ 2) / Ts
Can be calculated.

Next, in step S1006, the CPU 21 determines whether or not the calculated moving speed Vc is slower than a predetermined moving speed Vth. If the moving speed Vc is slower than the predetermined moving speed Vth, the process proceeds to step S1007. If the moving speed Vc is not slower than the predetermined moving speed Vth, the process proceeds to step S1012.
In step S <b> 1007, the CPU 21 determines that the user's finger or the mobile phone 8 that is close to or in contact with the screen of the display device 1 is substantially stopped. The CPU 21 compares the acquired coordinate value Pc with the coordinate information of the table, and determines whether there is a display area included in the coordinate value Pc.

In step S1008, when there is a display area, the CPU 21 determines whether information can be written to the IC tag at the present time. If the information cannot be written, the acquired coordinate value Vc is stored in step S1012. If information can be written, in step S1009, the CPU 21 writes information to the IC tag.
In step S1010, the CPU 21 sets a transmitted flag, and proceeds to step S1012. By setting the transmitted flag by the CPU 21, it is possible to prevent the same information from being written repeatedly.

  Thus, according to the fourth embodiment, not only when detecting whether or not the finger or the mobile phone 8 is approaching or touching, the IC tag is detected based on the detected moving speed. It is determined whether or not information can be written. Therefore, it is possible to prevent information unintended by the user from being written and provide only desired information.
