Since the sensor detection data indicating the presence state of the person includes data regarding whether or not the person has stayed for a certain period of time or longer, the stay determination means determines whether the person is near the sensor terminal based on the sensor detection data. It can be determined whether or not it stays for a certain period of time. According to this, when the distance between the sensor terminal and the person is short and the person is staying, the processing apparatus uses the content data associated with the highest degree of interest as the content data distributed by the information distribution terminal. select.

In this case, data such as product information and advertisement information provided from the information distribution terminal 17 (hereinafter referred to as “content data”) can be stored in advance in each information distribution terminal 17. For example, the information distribution terminal 17 installed in the book section can store a plurality of product information related to magazines in advance, and can reproduce the product information based on an instruction from the processing device 22. On the other hand, as another method, the content data may not be held in the information distribution terminal 17 but may be sequentially transmitted from the processing device 22 to the information distribution terminal 17 to be reproduced.

  In the example of FIG. 1, the transmitter / receiver 24 is illustrated as communicating with a single sensor terminal 15, but actually the transmitter / receiver 24 is configured to be able to communicate with all the sensor terminals 15 in the store 10. Is done. In FIG. 1, the processing device 22 is connected to a single information distribution terminal 17, but actually, the processing device 22 is connected to all the information distribution terminals 17 in the store 10.

  In addition, a sensor ID for identifying each sensor terminal is assigned to the sensor terminal 15.

[Sensor terminal]
The sensor terminal is a terminal that detects the presence state of an object such as a person. FIG. 2 is a block diagram showing the configuration of the sensor terminal 15. As illustrated, the sensor terminal 15 includes a power supply unit 31, a constant voltage generation unit 32, a control unit 33, a memory unit 34, a sensor unit 35, and a wireless communication unit 36.

  The power supply unit 31 is a battery (battery) that supplies power necessary to operate the sensor terminal 15. The constant voltage generation unit 32 is a circuit for transforming the output voltage of the power supply unit 31 to a voltage used inside the sensor terminal 15 and maintaining the voltage.

  The sensor unit 35 has a sensor function. The sensor function is a function that detects the presence state of an object such as a person using a carrier (medium) such as a radio wave such as a microwave, ultrasonic wave, or light, and generates sensor detection data indicating the presence state of the object. . Here, the presence state of an object such as a person is whether or not an object such as a person exists, the distance between the sensor terminal 15 and the object, whether or not the object stays for a certain period of time, the speed of the object, etc. It refers to various states related to the presence and movement of objects. The wireless communication unit 36 has a communication function. The communication function is a function for transmitting sensor detection data to the outside. The sensor unit 35 will be further described later.

  The memory unit 34 temporarily stores sensor detection data generated by the sensor unit 35. The memory unit 34 stores various control programs executed by the control unit 33.

  The control unit 33 is configured by a microprocessor, for example, and controls each unit in the sensor terminal 15. Specifically, the control unit 33 executes a control program stored in advance in the memory unit 34 to store sensor detection data in the memory unit 34, and a sensor stored in the memory unit 34. A process of transmitting the detection data to the processing device 22 via the wireless communication unit 36 is executed.

In principle, microwave sensors use the Doppler effect. The sensor unit 35 includes a transmission / reception device having a transmission unit that emits a microwave for detecting an object and a reception unit that receives a reflected wave of the emitted microwave. The sensor function irradiates a moving object with microwaves and receives reflected waves. When the transmission microwave and the reception microwave are compared, the frequency of the reception microwave shifts in proportion to the velocity of the object due to the Doppler effect. The sensor function of the sensor unit 35 uses this phenomenon to detect the presence and movement of an object. Specifically, the sensor unit 35 compares the frequencies of the transmission microwave and the reception microwave, generates sensor detection data indicating the presence or absence of an object, and supplies the sensor detection data to the control unit 33. The sensor detection data may be, for example, binary digital data having different levels depending on whether an object is present or absent. The control unit 33 temporarily stores the sensor detection data in the memory unit 34.

[Processing equipment]
The processing device 22 is a server that can communicate with the information distribution terminal 17 via a network or the like, and acquires and analyzes sensor detection data from a plurality of sensor terminals 15 in the store via the transceiver 24. Furthermore, the processing device 22 determines the degree of interest in the product displayed near the sensor terminal 15 based on the analysis result, and selects content data corresponding to the degree of interest. Then, the processing device 22 generates instruction information that is an instruction to distribute the selected content data, and transmits the instruction information to the information distribution terminal 17.

  FIG. 3 is a functional block diagram of the processing unit 50 configured by the components of the processing device 22. As illustrated in FIG. 3, the processing unit 50 includes a distribution information storage unit 100, a sensor detection data acquisition unit 101, an interest level determination unit 102, an instruction information generation unit 103, and an instruction information transmission unit 104.

  The distribution information storage unit 100 stores distribution information. FIG. 4 is a diagram illustrating a data configuration of distribution information in the present embodiment. As shown in the figure, the distribution information storage unit 100 includes a sensor ID, a product displayed near the sensor terminal identified by the sensor ID, a person's interest in the product, and a plurality of content data related to the product. Is stored. The distribution information storage unit functions as distribution information storage means in the present invention.

  In the distribution information in this embodiment, the interest level and the content data are associated with each other. However, the present invention is not limited to this, and the interest level and information for identifying the content data are associated with each other. It is good as well. That is, if the content selection unit described later can select content data corresponding to the degree of interest by referring to the distribution information, the data configuration is arbitrary.

  The sensor detection data acquisition unit 101 acquires sensor detection data indicating the presence state of an object such as a person from the sensor terminal 15 via the transceiver 24. The sensor detection data includes various information relating to the presence and movement of an object, such as whether or not an object such as a person exists, the distance between the sensor terminal 15 and the object, whether or not the object stays for a certain period of time, and the speed of the object. The data indicating the status of is included. The sensor detection data acquisition unit 101 functions as sensor detection data acquisition means in the present invention.

  The interest level determination unit 102 analyzes the sensor detection data acquired by the sensor detection data acquisition unit 101, and measures the position and speed of a person in the store. Then, the interest level determination unit 102 determines the interest level of the person with respect to the products displayed near the sensor terminal 15 based on the analysis result. The interest level determination unit 102 functions as an interest level determination unit in the present invention.

  The interest level determination unit 102 includes a person determination unit, a distance measurement unit, a speed measurement unit, and a stay determination unit.

  The person determination unit determines whether there is a person near the sensor terminal 15 by analyzing the sensor detection data. For example, if no person is detected after detecting that a person is moving in a direction away from the sensor terminal 15 based on the speed measured by the speed measuring unit described later, there is no person near the sensor terminal 15. judge. According to this, it becomes possible to estimate the degree of crowding of people. In this embodiment, the interest level determination unit 102 determines that the interest level is the lowest when the person determination unit determines that there is no person. The person determination unit functions as a person determination unit in the present invention.

  FIG. 5 shows the level of interest in this embodiment. In this embodiment, as shown in FIG. 5, the degree of interest has five levels. Specifically, the interest level determination unit 102 determines that there is no interest at all when the person determination unit determines that no person exists, and determines the interest level “1”. The degree of interest is not limited to this, and the stage and level can be arbitrarily set.

  The distance measuring unit measures the distance between the sensor terminal 15 and the person by analyzing the sensor detection data. According to this, it is possible to guess where the person is. When the distance measured by the distance measurement unit is equal to or greater than the threshold, the interest level determination unit 102 estimates that the distance between the product displayed near the sensor terminal 15 and the person is long, and determines the interest level for the product to be low. To do. The threshold value can be set arbitrarily. The distance measuring unit functions as a distance measuring unit in the present invention.

  The speed measurement unit measures the speed of the person included in the sensor detection data. The speed includes information on the traveling direction in addition to the speed itself. Specifically, the speed is information such as 4 km / h, and the traveling direction is information indicating, for example, a direction approaching a certain reference position with + and a direction away with −. In this example, when the speed of the person detected by the center terminal 15 is 4 km / h and the direction approaches the reference position, the sensor detection data becomes “+4 km / h”. The reference position in the present embodiment is the sensor terminal 15. As a result, it is possible to easily determine whether the person is approaching or moving away from the numerical value of the speed. The speed measuring unit functions as speed measuring means in the present invention.

  FIG. 6 is a diagram for explaining the speed. As shown in FIG. 6, when the person is moving without approaching or moving away from the sensor terminal 15a (near the product), the processing unit 100 determines that the person has passed.

  The speed itself is measured by the change value of the wavelength due to the passage of a person, and is proportional to the change value. The speed is large when the change value is large, and is small when the change value is small. In addition, when the reflected wave wavelength is shortened, it is assumed that the person is moving in the reference position, that is, in a direction approaching the sensor terminal 15, and when the reflected wave wavelength is long, the person moves away from the sensor terminal 15. It is measured by assuming that it is moving in the direction.

  The interest level determination unit 102 determines that the person is interested in the product based on the speed measured by the speed measurement unit, and determines that the person is interested in the product. Judge higher. Specifically, in this embodiment, the degree of interest is determined to be “4”. On the other hand, when the degree-of-interest determination unit 102 detects that a person is near the sensor terminal 15, that is, away from the product, based on the speed measured by the speed measurement unit, the interest level determination unit 102 determines that there is not much interest in the product. Decide the degree of interest at a low level. Specifically, in this embodiment, the interest level is determined to be “2”.

  Note that the interest level determination unit 102 can improve the detection accuracy of a person approaching or moving away from a product based on a plurality of speeds included in sensor detection data acquired from a plurality of sensor terminals 15. . For example, based on the speed included in the sensor detection data acquired from the sensor terminal 15a illustrated in FIG. 6, it is detected that a person has approached the sensor terminal 15a, and is included in the sensor detection data acquired from the sensor terminal 15b. When it is detected that the person has moved away from the sensor terminal 15b based on the speed, the interest level determination unit 102 determines that the product displayed near the sensor terminal 15a is interested.

  In addition, the interest level determination unit 102 determines that the person has passed early in front of the product based on the speed measured by the speed measurement unit, and that the interest in the product is quite low, Decide the degree of interest at a low level. Specifically, in this embodiment, the interest level is determined to be “2”. On the other hand, when the speed is low, it is determined that the person is passing the car while paying attention to the product, and is slightly interested in the product. In this embodiment, the interest level is determined to be “3”.

  The stay determination unit analyzes the sensor detection data, and measures the stay time indicating how long a person is in the vicinity of the sensor terminal 15, that is, before the product, based on the clock data and the measurement result by the speed measurement unit. For example, the stay determination unit estimates that a person is staying when sensor detection data is not received from the receiver 24 for a predetermined time or when the speed is “0”. Note that as the clock data, data by any clock function of the sensor terminal 15 and the processing device 22 may be used. Then, the stay determination unit determines whether or not a person stays in the vicinity of the sensor terminal 15, that is, in front of the product, for a predetermined time or more based on the measured stay time. The fixed time can be arbitrarily set. For example, the degree-of-interest determination unit 102 examines the product when the distance measured by the distance measurement unit is shorter than the threshold and the stay determination unit determines that a person is staying, or It is determined that the purchase of the product is lost and it is determined that the degree of interest is the highest. Specifically, in this embodiment, the interest level is determined to be “5”. The stay determination unit functions as a stay determination unit in the present invention.

  Note that the interest level determination unit 102 may determine the interest level using any of the above methods. Moreover, it is not limited to said method, It is good also as performing by the pattern analysis which utilized the some sensor detection data and combined the above.

  Specifically, in the case of a single sensor, basically it has only one detection function of the presence of a person, the distance from the target to the person, and the movement speed of the person. Detecting the approach of a person, detecting the position of a person approaching with an ultrasonic sensor, and again detecting the movement of the person in front of the target with a radio wave sensor. The degree of interest may be determined by combining the detected sensor data. In addition, according to a plurality of far-infrared sensors among infrared sensors, the surrounding temperature distribution can be detected. For example, it is detected that a radio wave sensor is approaching, and the temperature distribution detected by the plurality of far-infrared sensors is used. The degree of interest may be determined by analyzing whether the person is near or far, whether the person is alone or plural (group). In this way, by determining the interest level by combining a plurality of sensor detection data, it is possible to grasp a person's behavior in more detail and improve the accuracy of determination of the interest level.

  The instruction information generation unit 103 generates instruction information to be transmitted to the information distribution terminal 17 based on the interest level determined by the interest level determination unit 102 and is related to content data distribution. The instruction information generation unit 103 functions as instruction information generation means in the present invention.

  The instruction information generation unit 103 includes a content selection unit, a volume setting unit, and a luminance setting unit.

  The content selection unit stores the distribution information storage based on the sensor ID of the sensor terminal 15 that is the transmission source of the sensor detection data acquired by the sensor detection data acquisition unit 101 and the interest level determined by the interest level determination unit 102. Corresponding content data is selected from the distribution information stored in unit 100. The distribution information as shown in FIG. 4 associates content data according to the person's interest in the product. Specifically, in the distribution information in this embodiment, when the degree of interest is slightly low (for example, the degree of interest “3” or “2”), there are few people near the product or people pass through a place far from the product. Therefore, voice guidance that attracts people, LEDs, and lights (including eye catch) are associated as content data. In addition, when the degree of interest is high (for example, the degree of interest “5”), it is assumed that the person is near the product and is wondering about the purchase, so a service for making a purchase decision (for example, a recipe for cooking) And content data related to coupons. The content selection unit selects appropriate content data according to the degree of interest from such distribution information. The content data selection unit functions as content data selection means in the present invention.

  Based on the interest level determined by the interest level determination unit 102, the volume setting unit sets a volume level when content data is distributed by the information distribution terminal 17. Specifically, when the degree of interest is slightly low (for example, the degree of interest “3” or “2”), it is assumed that the product and the person are separated from each other. Set a higher volume. On the other hand, when the degree of interest is high (for example, the degree of interest “5”), it is assumed that there is a person in front of the product. Therefore, it is not necessary to set a large volume that attracts people. The instruction information generation unit includes the volume set by the volume setting unit in the instruction information as a volume when the content data is distributed. According to this, the volume at the time of distributing content data can also be adjusted according to the degree of human interest in the product. The volume setting unit functions as volume setting means in the present invention.

  The luminance setting unit sets the luminance of the screen when content data is distributed by the information distribution terminal 17 based on the interest level determined by the interest level determination unit 102. Specifically, when the interest level is slightly low (for example, the interest level “3” or “2”), the brightness setting unit sets a higher brightness so as to attract people. The instruction information generation unit includes the luminance set by the luminance setting unit in the instruction information as the luminance when the content data is distributed. According to this, the brightness at the time of distributing content data can also be adjusted according to the degree of human interest in the product. The luminance setting unit functions as luminance setting means in the present invention.

  The instruction information generation unit 103 sets the information distribution terminal 17 to switch to the energy saving mode when the degree of interest is low (for example, the degree of interest “1” or “2”), and uses the set instruction as instruction information. It may be included. Alternatively, the information distribution terminal 17 may be set to be turned off, and the set instruction may be included in the instruction information. The instruction information generation unit 103 also functions as power supply setting means in the present invention.

  In the present embodiment, as described above, the content data, volume, luminance, state, etc. distributed by the information distribution terminal 17 are set according to the degree of interest, but the present invention is not limited to this. The degree of interest and the content data distributed by the information distribution terminal 17, volume, luminance, state, etc. can be arbitrarily set.

  The instruction information transmission unit 104 transmits the instruction information generated by the instruction information generation unit 103 to the information distribution terminal 17. The information distribution terminal 17 is assigned a distribution terminal ID for identifying each information distribution terminal. The processing device 22 stores the distribution terminal ID of the information distribution terminal 17 installed in the vicinity of the sensor terminal 15 indicated by the sensor ID in advance in association with the sensor ID. Therefore, the instruction information transmission unit 104 specifies the distribution terminal ID based on the sensor ID of the sensor terminal 15 that is the transmission source of the sensor detection data acquired by the sensor detection data acquisition unit 101, and information corresponding to the specified distribution ID. Instruction information is transmitted to the distribution terminal 17. The instruction information transmission unit 104 functions as instruction information transmission means in the present invention.

  The information distribution terminal 17 outputs the content data selected by the processing device 22 with the set volume and / or brightness based on the instruction information received from the processing device 22. In some cases, the information distribution terminal 17 switches to the energy saving mode or turns off the power based on the instruction information received from the processing device 22.

[Delivery process]
Next, an example of distribution processing executed in the sensor system will be described. FIG. 7 is a flowchart of distribution processing executed in the sensor system. In addition, about this delivery process, the process especially performed by the processing apparatus 22 is demonstrated in detail. The processing executed by the processing device 22 is realized by the processing unit 50 executing the program prepared in advance by the processing unit 50.

  When the power is turned on, the sensor terminal 15 detects power supply by the control unit 33 shown in FIG. 2 and starts processing. First, the sensor unit 35 starts velocity measurement by generating a carrier such as a microwave and detecting an object such as a person (step S1). Subsequently, the control unit 33 determines whether or not the speed has been detected by speed measurement (step S2). When the speed is not detected (step S2; No), the process returns to step S1, and the speed measurement by the sensor unit 35 is continued. On the other hand, when the speed is detected (step S2; Yes), the wireless sensor 36 transmits the generated sensor detection data to the receiver 24 (step S3). When the transmission of the sensor detection data is completed, the process returns to step S1, and the speed measurement by the sensor unit 35 is continued.

  When the power is turned on, the receiver 24 stands by for receiving sensor detection data from the sensor terminal 15 (step S4). And the receiver 24 determines whether the sensor detection data was received from the sensor terminal 15 (step S5). If sensor detection data has not been received (step S5; No), the receiver 24 returns to step S4 and continues to wait for reception. On the other hand, when sensor detection data is received (step S5; Yes), the receiver 24 transmits the sensor detection data to the processing device 22 (step S6). When the transmission of the sensor detection data is completed, the process returns to step S4, and the reception standby is continued.

  When the power is turned on, the processing device 22 performs initial setting by the processing unit 50 (step S7). The initial setting is a setting for associating the sensor terminal 15 with a product displayed near the sensor terminal 15. Note that the distribution information is not stored in the processing device 22 in advance, but may be created by initial setting. In this case, the processing device 22 stores data in which products, interests, and content data are associated in advance. The distribution information created by the initial setting is stored in the distribution information storage unit 100 of the processing unit 50.

  When the initial setting is completed, the sensor detection data acquisition unit 101 waits for receiving sensor detection data from the receiver 24 (step S8). And the sensor detection data acquisition part 101 determines whether the sensor detection data was received from the receiver 24 (step S9). When sensor detection data has not been received (step S9; No), the person determination unit determines that there is no person near the sensor terminal 15, that is, near the product. When the person determination unit determines that no person exists, the interest level determination unit 102 determines that the person is not interested in the product at all, and determines the interest level as “1” (step S11). Accordingly, the content selection unit selects content data corresponding to the degree of interest “1” by referring to the distribution information stored in the distribution information storage unit 100. Furthermore, the instruction information generation unit 103 generates instruction information for distributing content data corresponding to the degree of interest “1”. Then, the instruction information transmission unit 104 transmits the generated instruction information to the information distribution terminal 17 (step S19). When the transmission of the instruction information is completed, the processing unit 50 returns to step S8 and continues the reception standby.

  When the sensor detection data is received (step S9; Yes), the interest level determination unit 102 determines that the person is interested in the product and determines the interest level as “4” (step S10). Therefore, the content selection unit selects content data corresponding to the degree of interest “4” by referring to the distribution information stored in the distribution information storage unit 100. Furthermore, the instruction information generation unit 103 generates instruction information for distributing content data corresponding to the degree of interest “4”. Then, the instruction information transmission unit 104 transmits the generated instruction information to the information distribution terminal 17 (step S12). Subsequently, the sensor detection data acquisition unit 101 waits to receive sensor detection data from the receiver 24 in order to determine the next state (step S13).

  The sensor detection data acquisition unit 101 determines whether sensor detection data has been received from the receiver 24 within a predetermined time (step S14). When sensor detection data has not been received (step S14; No), the stay determination unit determines that a person is staying in a state of approaching the product. When it is determined by the stay determination unit that the user is staying, the interest level determination unit 102 determines that the person is considerably interested in the product, and determines the interest level as “5” (step S15). Therefore, the content selection unit selects content data corresponding to the degree of interest “5” by referring to the distribution information stored in the distribution information storage unit 100. Furthermore, the instruction information generation unit 103 generates instruction information for distributing content data corresponding to the degree of interest “5”. Then, the instruction information transmission unit 104 transmits the generated instruction information to the information distribution terminal 17 (step S19). When the transmission of the instruction information is completed, the processing unit 50 returns to step S8 and continues the reception standby.

  When the sensor detection data is received within a certain time (step S14; Yes), the interest level determination unit 102 determines whether or not the speed value measured by the speed measurement unit is equal to or greater than a preset threshold value. (Step S16). When it is determined that the speed is equal to or higher than the threshold (step S16; Yes), the interest level determination unit 102 determines that the person is not very interested in the product because the person is moving away from the product at a high speed. The degree of interest is determined as “2” (step S17). Accordingly, the content selection unit selects content data corresponding to the degree of interest “2” by referring to the distribution information stored in the distribution information storage unit 100. Furthermore, the instruction information generation unit 103 generates instruction information for distributing content data corresponding to the degree of interest “2”. Then, the instruction information transmission unit 104 transmits the generated instruction information to the information distribution terminal 17 (step S19). When the transmission of the instruction information is completed, the processing unit 50 returns to step S8 and continues the reception standby.

  On the other hand, when it is determined that the speed is less than the threshold (step S16; No), the interest level determination unit 102 determines that the person is slightly interested in the product because the person is slowly moving away from the product. Then, the degree of interest is determined to be “3” (step S18). Therefore, the content selection unit selects the content data corresponding to the degree of interest “3” by referring to the distribution information stored in the distribution information storage unit 100. Furthermore, the instruction information generation unit 103 generates instruction information for distributing content data corresponding to the degree of interest “3”. Then, the instruction information transmission unit 104 transmits the generated instruction information to the information distribution terminal 17 (step S19). When the transmission of the instruction information is completed, the processing unit 50 returns to step S8 and continues the reception standby.

  When the power is turned on, the information distribution terminal 17 waits for receiving instruction information from the processing device 22 (step S20). Then, the information distribution terminal 17 outputs the content data based on the instruction information received from the processing device 22 and performs distribution (step S21). Thereby, the distribution process by the sensor system is completed.

  In this distribution process, it is necessary to switch the content data to be distributed at the moment when the state of the person changes. Therefore, when the sensor terminal 15 detects a change in the state of the person, the sensor terminal 15, the receiver 24, and the processing device 22. The information distribution terminal 17 performs data communication in real time.

  Further, although not executed in this distribution process, the instruction information generated by the processing device 22 may include information related to the volume and luminance when distributing the content data.

  Further, in the flowchart of the process executed by the sensor terminal 15 in this distribution process, when the sensor terminal 15 detects the speed, the sensor detection data is continuously transmitted to the receiver 24 during the detection. However, the application of the present invention is not limited to this, and the sensor detection data may be transmitted to the receiver 24 only when at least one of the speed and the traveling direction changes. In this case, for example, once the sensor terminal 15 transmits the sensor detection data “+4 km / h” to the receiver 24, the sensor terminal 15 does not transmit until it changes, and then changes from “+4 km / h” to “+6 km / h” When it changes to “−3 km / h” or the like, the sensor detection data “+6 km / h” or “−3 km / h” after the change is transmitted to the receiver 24.

  As described above, according to the sensor system of the present embodiment, sensor detection data is received from the plurality of sensor terminals 15 in the store and analyzed, so that at which position in the store there is a person and at which position. Judging whether there are people. Furthermore, based on the analysis result, the degree of interest of the person with respect to the product is determined, and appropriate content data corresponding to the degree of interest is output from the information distribution terminal 17. Further, the volume, brightness, state, and the like when the information distribution terminal 17 distributes content data are adjusted according to the degree of interest.

  According to this, since effective and appropriate information distribution according to each person can be automatically performed, effective advertisement that increases the person's willingness to purchase becomes possible. In addition, it is possible to reduce waste of distributing content data when there are no people and to reduce operating costs. That is, it is possible to perform optimal information distribution that has a great effect on sales improvement. Moreover, it is good also as calculating automatically the person, ie, customer's action pattern which the processing apparatus 22 analyzed based on the sensor detection data, and utilizing this for the next merchandise display, a store clerk's arrangement place, a store enforcement method, etc.

  The sensor system of this embodiment can be applied not only to stores such as supermarkets, convenience stores, department stores, but also to event venues such as exhibitions, museums, and art galleries.

  When the sensor system of the present embodiment is applied to exhibitions, museums, art galleries, etc., the distribution information storage unit 100 stores distribution information as shown in FIG. The content selection unit stores the distribution information storage based on the sensor ID of the sensor terminal 15 that is the transmission source of the sensor detection data acquired by the sensor detection data acquisition unit 101 and the interest level determined by the interest level determination unit 102. Corresponding content data is selected from the distribution information stored in unit 100. The distribution information shown in FIG. 8 associates content data corresponding to the degree of interest of people with respect to exhibits. Specifically, when the interest level is low (for example, the interest level “1”), processing for turning off the display is associated as content data for energy saving. Further, when the degree of interest is medium (for example, degree of interest “3”), still image display and voice guidance that are eye-catching are associated as content data. When the degree of interest is high (for example, the degree of interest “5”), the display of the exhibit or the author's introduction, the next guidance flyer / coupon, and the like are associated as content data. The content selection unit selects appropriate content data according to the degree of interest from such distribution information.
