An encoding process or the like when transmitting _D1 to the distribution terminal 30 is performed.

On the other hand, the database interface 43 manages the exchange of the sensor identification information ID ₁ and the guidance information GV _D1 with the content database 50 under the control of the CPU 44.

  In parallel with these operations, the CPU 44 stores the necessary data in the storage unit 42 in a volatile or non-volatile manner based on the contents of the operation performed by the user using the operation unit 45, and in the first embodiment. The processing of each of the above constituent members as the content server 40 is comprehensively controlled so as to be processing according to a flowchart described later. The data to be presented to the user in the overall control operation is displayed on the display unit 46 and the presentation is made.

  Finally, the detailed configuration and operation of the sensor terminal 10 according to the first embodiment will be described with reference to FIG.

As shown in FIG. 3, the sensor terminal 10 according to the first embodiment includes a light emitting / receiving unit 11 as a distance detecting unit, a processing unit 12 as a distance detecting unit, a CPU 17, and data as a sensor device transmitting unit. The transmitter / receiver 18 and a storage unit 10M (stores various data and programs (for example, a sensor program)) including both a nonvolatile area and a volatile area are included. The processing unit 12, the CPU 17, the data transmission / reception unit 18, and the storage unit 10 </ b> M are configured to be able to exchange data with each other via the bus 19. At this time, the sensor identification information ID ₁ to which the sensor terminal 10 is assigned is stored in the storage unit 10M in a nonvolatile manner. The processing unit 12 stores a time / distance table of the length measurement light received by the light emitting / receiving unit 11 indicating the correspondence between the time from the light emission to light reception and the distance in a nonvolatile manner.

  In this configuration, the light emitting / receiving unit 11 is configured to measure the light for length measurement (in the flowchart shown in FIG. 4 to be described later, the light is referred to as “sensor wave”) at the distance set in advance in front of the light. Injection is performed so as to scan within the range (see step S11 in FIG. 4). And when the said light is reflected by the guidance terminal 20 itself or the user carrying the said guidance terminal 20 and returns to the light emission / light-receiving part 11 again, the said reflected light will be light-received and the time from the light emission to light reception will be received. It outputs to the process part 12 as time information.

  Accordingly, the processing unit 12 refers to the time / distance table based on the time information output from the light emitting / light receiving unit 11, and thereby the sensor terminal to the user or the like to which the received reflected light is reflected. The distance from 10 is calculated as length measurement data, and is output to the storage unit 10M via the bus 19 and temporarily stored (see step S12 in FIG. 4).

Next, the data transmitter / receiver 18 associates the stored length measurement data with the sensor identification information ID ₁ under the control of the CPU 17. Thereafter, under the control of the CPU 17, the data transmitting / receiving unit 18 transmits the associated length measurement data and sensor identification information ID ₁ to the guidance terminal 20 via the bus 19, the processing unit 12, and the light emitting / receiving unit 11 (FIG. (See 4 step S13).

  In parallel with these operations, the CPU 17 stores the necessary data in the storage unit 10M in a volatile or non-volatile manner and processes the components described above as the sensor terminal 10 according to the first embodiment. Overall control is performed so that the processing is in accordance with the flowchart.

  In the above description, the case where the distance from the sensor terminal 10 is optically measured has been described. However, in the case of length measurement using ultrasonic waves, by replacing the length measurement medium from light to ultrasonic waves, The above-described length measuring method can be applied as it is.

  When radio waves are used for length measurement, for example, the received strength of radio waves for length measurement is converted into so-called RSSI (Received Signal Strength Indicator), and a strength / distance table stored in advance in relation to the RSSI is used. It is preferable to generate length measurement data by referring to it. At this time, the length measurement data is generated in the sensor terminal 10 together with the transmission of the length measurement radio wave and the reception of the reflected wave (from the user), and the result is transmitted to the guidance terminal 20 via the radio wave. It can be configured to transmit. Further, the length measurement radio wave transmitted from the sensor terminal 10 may be received by the guidance terminal 20, thereby generating the length measurement data in the guidance terminal 20.

  Next, the operations of the sensor terminal 10, the guidance terminal 20, the distribution terminal 30, and the content server 40 according to the first embodiment will be described with reference to FIGS. A description will be given in chronological order. FIG. 4 is a flowchart showing the operation of the sensor terminal 10 and the like, and FIG. 5 is a diagram specifically illustrating an aspect of user detection by the sensor terminal 10.

  As shown in the left end of FIG. 4, first, when the power switch is turned on (step S10), the sensor terminal 10 according to the first embodiment can detect the transmission of the sensor wave for detecting the presence of the user. It starts to scan the entire area (step S11). As described above, this sensor wave differs depending on the detection method of the presence of the user. Specifically, radio waves, light (including infrared rays), ultrasonic waves, or the like is used. Further, as shown in FIG. 5, for example, the detectable region has a substantially triangular shape having the position of each sensor terminal 10 as one of the vertices and extending in the front direction of the sensor terminal 10. Region A1 or A2. When the user H moves into the detectable area A1 or A2, each sensor terminal 10 receives (receives) the sensor wave reflected by the user again, so that the user H moves. This is detected at each sensor terminal 10.

  When the presence of the user H can be detected in the detectable area A1 or A2 by the irradiation of the sensor wave, the sensor terminal 10 next detects the distance between the detected user H and the detected sensor terminal 10. Is measured (step S12). More specifically, the distance between the sensor terminal 10 and the guidance terminal 20 carried by the user H located in front of the sensor terminal 10 is measured. Various methods can also be used for this length measurement operation, such as a method using radio waves, a method using light, a method using ultrasonic waves, etc. For example, the size of the sensor terminal 10 and the required accuracy, etc. Based on this, it is determined which method to adopt.

  For example, when there is only one user H in one detectable area A1 as illustrated in FIG. 5A, the length measurement as the operation in step S12 is simply to use the reflected wave of the sensor wave as the sensor terminal 10. This is possible if light is received (received) at. On the other hand, when one user H exists simultaneously in each of the two detectable areas A1 and A2 as illustrated in FIG. 5B, there is a possibility that the distance from each sensor terminal 10 cannot be measured accurately due to interference. is there. For this reason, each sensor terminal 10 according to the first embodiment differs in the wavelength of the sensor wave transmitted from each sensor terminal 10. Thereby, each sensor terminal 10 can accurately measure the distance to the user H by receiving (receiving) the reflected wave having the same wavelength as the sensor wave transmitted by itself.

When the distance between the sensor terminal 10 and the guidance terminal 20 is measured, the sensor terminal 10 next detects the sensor identification information ID ₁ for identifying itself (the sensor terminal installed in the vicinity of the exhibit D1). 10) or ID ₂ (in the case of the sensor terminal 10 installed close to the exhibit D2) and length measurement data R ₁ (installed close to the exhibit D1) as a result of the operation of step S12 above. The sensor terminal 10) or R ₂ (in the case of the sensor terminal 10 installed in the vicinity of the exhibit D2) as a pair and carried by a user located in front of the sensor terminal 10 (Step S13; see step S21 in FIG. 4 and FIG. 5).

In the following description, the sensor identification information ID ₁ or ID ₂ is simply referred to as sensor identification information ID ₁ or the like, and the length measurement data R ₁ or R ₂ is simply referred to as length measurement data R ₁ or the like.

  Thereafter, the sensor terminal 10 confirms whether or not its power switch is turned off (step S14). If the power switch is not turned off (step S14; NO), the process returns to step S11 as it is. The series of operations described above is repeated. On the other hand, when the power switch of the sensor terminal 10 is turned off in the determination in step S14 (step S14; YES), the operation as the sensor terminal 10 is stopped as it is.

  Next, operation | movement of the guidance terminal 20 which concerns on 1st Example is demonstrated using the 2nd flowchart from the left of FIG.

As shown in the flowchart, when the CPU 27 in the guidance terminal 20 is carried by the user and the power switch is turned on (step S20), the sensor identification information ID _{1 and the} like from the sensor terminal 10 and the measurement are measured. length data _{R 1} etc., it starts monitoring whether it receives (see step S21. FIG. 4 step S13). If the sensor identification information ID ₁ or the like and the length measurement data R ₁ or the like are not received (step S21; NO), the CPU 27 continues monitoring as it is. On the other hand, when the sensor identification information ID ₁ or the like and the length measurement data R ₁ or the like are received (step S21; YES), the CPU 27 next displays the sensor terminal 10 and the guidance terminal indicated by the received length measurement data R ₁ or the like. The distance to 20 is compared with a distance threshold that is preset and stored in the storage unit 20M (steps S22 and S23). Configuration Here, the distance threshold measurement when the distance data is represented by R ₁ or the like is less than the distance threshold, the user that carries the guidance terminal 20, proximate the corresponding sensor terminal 10 It is a distance threshold value that is set in advance as a reference distance that is determined to be viewing the displayed exhibition D1 or the like (see symbol L in FIG. 5A).

In the determination of step S23, when the distance indicated by the received measurement data _{R 1,} etc. is greater than or equal to the distance threshold value (Step S23; YES), CPU 27, the user is still correspond that carries the guidance terminal 20 It is determined that the exhibit D1 or the like to be viewed is not being viewed, and the process returns to step S21 to repeat the series of operations described above. On the other hand it is determined in step S23, it is less than the distance threshold distance indicated by the received measurement data _{R 1} etc. (i.e., less than the distance threshold) when (Step S23; NO), CPU 27, the guidance terminal 20 Next, the sensor identification information ID ₁ and the length measurement data R ₁ received in the operation of step S21 are determined. The guidance terminal identification information IDG ₁ for identifying the guidance terminal 20 itself from the other guidance terminal 20 (in the case of the guidance terminal 20 carried by the user H who is viewing the exhibition D1) or IDG ₂ (In the case of the guidance terminal 20 carried by the user H who is viewing the exhibit D2) is added (step S24). Thereafter, the CPU 27 transmits all of these data from the guidance terminal 20 to the distribution terminal 30 (step S25).

In the following description, the guidance terminal identification information IDG ₁ or IDG ₂ is simply referred to as guidance terminal identification information IDG ₁ or the like.

Further, for example, as illustrated in FIG. 5B, one guidance terminal 20 receives the sensor identification information ID ₁ and ID ₂ and the length measurement data R ₁ and R ₂ from the plurality of sensor terminals 10. when and distance indicated by either the measurement data R ₁ and R ₂ Te were also beyond the distance threshold L, CPU 27 as the processing of the step S24, all the data received (i.e., the sensor identification information ID ₁ And ID ₂ and length measurement data R ₁ and R ₂ ), one guidance terminal identification information IDG (in the example of FIG. 5B, one for identifying the guidance terminal 20 carried by the user H) Guidance terminal identification information IDG) is added. Then, the CPU 27 provides one guidance for each pair of data including the one guidance terminal identification information IDG (specifically, in the case of FIG. 5B, including the sensor identification information ID ₁ and the length measurement data R _1). The data to which the terminal identification information IDG is added and the data including the sensor identification information ID ₂ and the length measurement data R ₂ to which one guidance terminal identification information IDG is added are separately transmitted to the distribution terminal 30 ( Step S25).

Thereafter, the CPU 27 sends the guidance information GV _D1 (in the case of the guidance terminal 20 carried by the user H who is viewing the exhibit D1) or GV _D2 (the user who is viewing the exhibit _D2 ) from the distribution terminal 30. It is monitored whether or not the guidance terminal 20 carried by H has been transmitted (step S26). When the guidance information GV _D1 or GV _D2 has not yet been transmitted (step S26; NO), the monitoring operation is continued as it is, while when the guidance information GV _D1 or GV _D2 has been transmitted (step S26). YES), the CPU 27 controls the data transmitting / receiving unit 28 and the audio decoder 23 to cause the user carrying the content of the received guidance information GV _D1 or GV _D2 as a voice. Thereafter, the CPU 27 deletes the reproduced guidance information GV _D1 or GV _D2 from the storage unit 36 (step S27).

In the following description, the guidance information GV _D1 or GV _D2 is simply referred to as guidance information GV _D1 or the like.

  Further, the guidance information GV and the voice decoder 23 may be configured such that the guidance information GV itself is character information (text information) and is voiced by the voice decoder 23, and the guidance information GV itself is voice information. This can be configured such that the sound data 23 is decoded as it is and emitted. In the case of the former in this configuration, the amount of data as the guidance information GV exchanged between the distribution terminal 30 and the guidance terminal 20 can be minimized, so that the transmission speed is increased and the storage capacity of the content database 50 is increased. Can be minimized. In the latter case, since the guidance information GV as the received voice information may be decoded as it is, the configuration as the voice decoder 23 is simplified, the processing load as the guidance terminal 20 is reduced, and the size / weight is reduced. Minimization of electric power can be realized.

  Thereafter, the CPU 27 confirms whether or not the power switch of the guidance terminal 20 provided therein is turned off (step S28). When the power switch is not turned off (step S28; NO), the CPU 27 directly performs the above process. It returns to step S21 and repeats a series of operation | movement mentioned above. On the other hand, when the power switch of the guidance terminal 20 is turned off in the determination in step S28 (step S28; YES), the operation as the guidance terminal 20 is stopped as it is.

  Next, the operation of the distribution terminal 30 according to the first embodiment will be described using the second flowchart from the right in FIG.

As shown in the flowchart, when the power switch of the CPU 35 in the distribution terminal 30 is turned on (step S30), the sensor identification information ID ₁ or the like and the length measurement data R from any guidance terminal 20 are displayed. _{1 and the} guidance terminal identification information IDG ₁ are monitored (step S31; see step S25 in FIG. 4). If the sensor identification information ID ₁ or the like, the length measurement data R ₁ or the like, and the guidance terminal identification information IDG ₁ or the like are not received (step S31; NO), the CPU 35 continues monitoring as it is. On the other hand, when the sensor identification information ID _{1 and the} like, the length measurement data R _{1 and the} like, and the guidance terminal identification information IDG _{1 and the} like are received (step S31; YES), the CPU 35 next temporarily stores the received data and the like. Is stored in the storage unit 36 (step S32). Next, the CPU 35 stores whether or not a plurality of sensor identification information ID _{1 and the} like and length measurement data R _{1 and the} like are primarily stored as a pair of one guidance terminal identification information IDG (for example, guidance terminal identification information IDG ₁ ). It confirms in the part 36 (step S33).

In the determination in step S33, only one sensor identification information ID (for example, sensor identification information ID ₁ ) and length measurement data R (for example, length measurement data R ₁ ) are primarily stored as a pair of one guidance terminal identification information IDG. In the case (step S33; NO), the CPU 35 proceeds to the process of step S35 described later. On the other hand, in the determination of step S33, when a plurality of sensor identification information ID _{1 and the} like and length measurement data R _{1 and the} like are primarily stored as a pair of one guidance terminal identification information IDG (step S33; YES), the CPU 35 next Among the plurality of sensor identification information ID _{1 and the} like and length measurement data R _{1 and the} like stored as a pair of the one guidance terminal identification information IDG, the one having the shortest distance indicated by the length measurement data R is selected ( Step S34). Thereafter, the CPU 35 detects the sensor identification information ID (for example, sensor identification information ID ₁ ) and the guidance terminal identification information IDG (for example, guidance identification information IDG ₁ ) that were paired with the length measurement data R selected in the operation of step S34. ) To the content server 40 from the distribution terminal 30 (step S35).

Thereafter, the CPU 35 receives the guidance information GV (for example, guidance information GV _D1 ) from the content server 40 together with the guidance terminal identification information IDG (for example, guidance terminal identification information IDG ₁ ) for identifying the guidance terminal 20 to which the guidance information 20 is to be distributed. It is monitored whether or not it has been transmitted (step S36). When the guidance information GV and the guidance terminal identification information IDG have not been transmitted yet (step S36; NO), the monitoring operation is continued as it is, while the guidance information GV and the guidance terminal identification information IDG have been transmitted. In the case (step S36; YES), the CPU 35 controls the data transmitting / receiving unit 28 and the wireless interface 32 to direct the received guidance information GV to the guidance terminal 20 identified by the received guidance terminal identification information IDG. (Step S37; see step S26 in FIG. 4).

  Thereafter, the CPU 35 checks whether or not the power switch of the distribution terminal 30 provided therein is turned off (step S38), and when the power switch is not turned off (step S38; NO), the CPU 35 directly performs the above process. Returning to step S31, the series of operations described above is repeated. On the other hand, if it is determined in step S38 that the power switch of the distribution terminal 30 is off (step S38; YES), the operation as the distribution terminal 30 is stopped as it is.

  Finally, the operation of the content server 40 according to the first embodiment will be described using the flowchart shown at the right end of FIG.

As shown in the flowchart, when the power switch of the CPU 44 in the content server 40 is turned on (step S40), the sensor identification information ID _{1 and the} like from the distribution terminal 30 and the guidance terminal identification information IDG _{1 and the} like. Is started (step S41; see step S35 in FIG. 4). If the sensor identification information ID ₁ or the like and the guidance terminal identification information IDG ₁ or the like are not received (step S41; NO), the CPU 44 continues monitoring as it is. On the other hand, when the sensor identification information ID ₁ etc. and the guidance terminal identification information IDG ₁ etc. are received (step S41; YES), the CPU 44 next receives the received sensor identification information ID ₁ etc. and the guidance terminal identification information IDG ₁ etc. Guidance information GV _{D1 and the} like associated with is searched / extracted in the content server 50, and the corresponding reproduced flag in the extracted guidance information GV _{D1 and the} like is set to “not reproduced”. Information GV (for example, guidance information GV _D1 ) is selected (step S42).

Then, the CPU 44 confirms whether or not the guidance information GV whose reproduction flag is set to “unreproduced” has been selected (step S43), and if it has been selected (step S43; YES), the process proceeds to step S45 to be described later. Transition to processing. On the other hand, when there is no extracted guidance information GV _D1 or the like in which the corresponding reproduced flag is set to “not reproduced” (step S43; NO), the CPU 44 then extracts the extracted guidance information GV _D1. The guidance information GV having the smallest number of times of reproduction is selected from the number of times of reproduction indicated by the number of times of reproduction corresponding to each of the above (step S44).

  Then, the CPU 44 next selects the guidance information GV selected by the operation of step S42 or S44 and the guidance terminal identification information IDG for identifying the guidance terminal 20 to be reproduced (in other words, by the operation of step S41). The received guidance terminal identification information IDG, which is associated with the selected guidance information GV), is transmitted as a pair from the content server 40 to the distribution terminal 30 (step S45; see step S36 in FIG. 4). . Thereafter, the CPU 44 changes the content of the replayed flag corresponding to the guidance information GV transmitted by the operation of step S45 to “reproduced” in the content database 50, and similarly changes the content of the corresponding replay count flag. Increment by "1".

  Thereafter, the CPU 44 confirms whether or not the power switch of the content server 40 is turned off (step S46). If the power switch is not turned off (step S46; NO), the CPU 44 returns to the step S41 as it is and described above. Repeat the series of operations. On the other hand, if it is determined in step S46 that the power switch of the content server 40 is turned off (step S46; YES), the operation as the content server 40 is stopped as it is.

By the operation of the sensor terminal 10 according to the first embodiment described above, the user H who has moved in front of each exhibit D can listen to the guidance information GV related to the exhibit D in a timely manner. it can. In addition, for example, as illustrated in FIG. 5B, even when one user H exists simultaneously in the detectable areas A1 and A2 related to the plurality of sensor terminals 10, the guidance terminal carried by the user H is present. Guidance information GV about the exhibition D (exhibit D1 in the case of FIG. 5B) that is closest to the user H based on the distance between the sensor terminal 10 and each sensor terminal 10. _D1 can be heard from the guidance terminal 20 by the user H.

  Next, a second example, which is another example of the present invention in accordance with the above embodiment, will be described with reference to FIGS. 1, 2, 3, 6, and 7. In the second embodiment described below, the distance between the sensor terminal 10 and the guidance terminal 20 carried by the user who has moved into the detectable area is measured at the guidance terminal 20. This is an example.

  The detailed configurations of the sensor terminal 10, the guidance terminal 20, the distribution terminal 30 and the content server 40 according to the second embodiment are basically the same as those of the sensor terminal 10, the guidance terminal 20, the distribution terminal 30 and the first embodiment. The detailed configuration of each of the content servers 40 is the same. Therefore, in the following description, description of the detailed configuration of the sensor terminal 10 and the like according to the second embodiment is omitted by substituting the member numbers of FIGS. 2 and 3 and the constituent members used therein.

  Next, the operations of the sensor terminal 10, the guidance terminal 20, the distribution terminal 30, and the content server 40 according to the second embodiment will be described with reference to FIGS. 6 and 7, taking the case of the viewing assistance system S shown in FIG. A description will be given in chronological order. FIG. 6 is a flowchart showing the operation of the sensor terminal 10 and the like, and FIG. 7 is a diagram specifically illustrating an aspect of user detection by the sensor terminal 10. 6 and 7, the same operations and members as those of the first embodiment shown in FIGS. 4 and 5 are denoted by the same step numbers and the same member numbers, and detailed description thereof is omitted.

  As shown in the left end of FIG. 6, first, in the sensor terminal 10 according to the second embodiment, operations similar to those in steps S10 and S11 in the operation of the sensor terminal 10 according to the first embodiment are executed (FIGS. 6 and 4). Steps S10 and S11).

Then, when the presence of the user H can be detected in the detectable area A1 or A2 (see FIG. 7) by irradiation of the sensor wave from each sensor terminal 10, the sensor terminal 10 next identifies itself. Only the sensor identification information ID ₁ or the like is transmitted from the sensor terminal 10 to the guidance terminal 20 carried by the user located in front of the sensor terminal 10 (step S15; see steps S21 and 7 in FIG. 6).

Here, in the case of the second embodiment, for example, when it is detected that a plurality of users H1 to H3 exist in one detectable area A1 as illustrated in FIG. 20, the same sensor identification information ID ₁ is received from the sensor terminal 10.

  Thereafter, the sensor terminal 10 performs the same operation as step S14 in the operation of the sensor terminal 10 according to the first embodiment (step S14 in FIGS. 6 and 4), and serves as the sensor terminal 10 according to the second embodiment. Stop operation.

  Next, operation | movement of the guidance terminal 20 which concerns on 2nd Example is demonstrated using the 2nd flowchart from the left of FIG.

As shown in the flowchart, the CPU 27 in the guidance terminal 20 first executes the same operations as steps S20 and S21 in the operation of the guidance terminal 20 according to the first embodiment (steps S20 and S21 in FIGS. 6 and 4). ). When only the sensor identification information ID ₁ or the like is received (step S21; YES), the CPU 27 next measures the distance between the guidance terminal 20 provided with the sensor identification information ID ₁ and the sensor terminal 10 (step S29). ). More specifically, the distance between the guidance terminal 20 and the sensor terminal 10 that has transmitted the sensor identification information ID ₁ or the like to the guidance terminal 20 is measured. Various methods can also be used for this length measurement operation, such as a method using radio waves, a method using light, or a method using ultrasonic waves, such as the size of the guidance terminal 20 and the required accuracy. Based on this, it is determined which method to adopt.

  For example, when there are a plurality of users H1 to H3 in one detectable area A1 as illustrated in FIG. 7A, the length measurement as the operation in step S29 is simply from one sensor terminal 10. This is possible if the sensor waves are received (received) separately at each guidance terminal 20. Further, even when the user H1 exists simultaneously in each of the two detectable areas A1 and A2 as illustrated in FIG. 7B, the user H1 carries a sensor wave having a different wavelength from each sensor terminal 10. By receiving (receiving) each at the terminal 20, each sensor terminal 10 can be identified and the distance between the user H1 and each sensor terminal 10 can be accurately measured.

  When the distance between the sensor terminal 10 and the guidance terminal 20 is measured, the CPU 27 next sets the measured distance between the sensor terminal 10 and the guidance terminal 20 to be the same as the distance threshold according to the first embodiment. (Steps S22 and S23, see FIG. 5A and reference L).

When the distance measured in the determination in step S23 is equal to or greater than the distance threshold (step S23; YES), the CPU 27 still appreciates the corresponding exhibit D1 etc. by the user carrying the guidance terminal 20. If not, the process returns to step S21 to repeat the series of operations described above. On the other hand, in the determination of step S23, when the measured distance is not equal to or greater than the distance threshold (that is, less than the distance threshold) (step S23; NO), the CPU 27 corresponds to the user carrying the guidance terminal 20. In order to identify the guidance terminal 20 itself from other guidance terminals 20 with respect to the sensor identification information ID ₁ etc. already received in the operation of step S21. The guidance terminal identification information IDG _{1 and the} like, and length measurement data R _{1 and the} like indicating the distance measured by the operation of step S29 are added (step S29-1). Thereafter, the CPU 27 transmits all of these data from the guidance terminal 20 to the distribution terminal 30 (step S25).

For example, as illustrated in FIG. 7B, one guidance terminal 20 receives the sensor identification information ID ₁ and ID ₂ from a plurality of sensor terminals 10 and any distance (in step S29). When the distance measured in the operation) also exceeds the distance threshold value L, the CPU 27 performs processing for the received data (that is, the sensor identification information ID ₁ and ID ₂ ) as the process of step S29-1. The length measurement data R ₁ and R ₂ corresponding to the sensor identification information ID ₁ and ID ₂ respectively, and one guidance terminal identification information IDG (in the example of FIG. 7B, the guidance terminal carried by the user H1 One guidance terminal identification information IDG) for identifying 20 is added. Then, the CPU 27 adds each of the data to which the one guidance terminal identification information IDG is added (specifically, in the case of the user H1 in FIG. 7B, a pair including the sensor identification information ID ₁ and the length measurement data R ₁₎ . The distribution terminal 30 separately distributes data in which one guidance terminal identification information IDG is added to each other and data in which one guidance terminal identification information IDG is added to a pair including the sensor identification information ID ₂ and the length measurement data R _2. (Step S25).

  Thereafter, the CPU 27 executes the same operations as steps S27 and S28 in the operation of the guidance terminal 20 according to the first embodiment (steps S27 and S28 in FIGS. 6 and 4), and serves as the guidance terminal 20 according to the second embodiment. Stop the operation.

  Next, the operations of the distribution terminal 30 and the content server 40 according to the second embodiment are all executed by the same operations of the distribution terminal 30 and the content server 40 according to the first embodiment ( 6 and 4 steps S30 to S38 and steps S40 to S46).

  Even in the case of the operation of the sensor terminal 10 or the like according to the second embodiment described above, as in the case of the first embodiment, the user H who has moved in front of each exhibition D is well-timed. The guidance information GV regarding the exhibit D can be heard.

  Further, for example, as illustrated in FIG. 7A, even when a plurality of users H1 to H3 are present simultaneously in the detectable area A1 related to one sensor terminal 10, the users H1 to H3 are respectively carried.
