1. SYSTEM OVERVIEW
FIG. 1 is a schematic diagram of a content selection system 1 in an embodiment of the present invention. In FIG. 1, a state of the inside of an art museum is depicted. Inside of the museum, together with exhibits such as paintings, output equipment 500 which outputs content related to the exhibits is installed. The output equipment 500 is, for example, a speaker or a display. The output equipment 500 outputs content with audio or video according to instructions from a management apparatus 100 installed in other area.
Also, inside of the museum, a distribution apparatus 300 is installed which transmits a positioning signal according to IMES (Indoor Messaging System) Standard which is a standard related to positioning technology for indoors. The distribution apparatus 300 is provided, for example, as a built-in distribution apparatus in a lighting fixture installed on the ceiling. The distribution apparatus 300 distributes information of a location at which the distribution apparatus 300 is installed, in a range indicated by a dotted line in FIG. 1. Also, the distribution apparatus 300 forms a wireless network together with a gateway 400 which is separately installed inside the museum. The wireless network is formed by using, for example, ZigBee (registered trademark) or Bluetooth (registered trademark).
A visitor who appreciates exhibits has a wireless terminal 200 in which unique attributes of the visitor (e.g., age, gender) are recorded. The wireless terminal 200 may receive the positioning signal transmitted by the distribution apparatus 300 and obtains location information. Also, the wireless terminal 200 may participate in the network formed by the distribution apparatus 300 and the gateway 400. The wireless terminal participating in the network transmits the location information obtained from the distribution apparatus 300 and the attribute information recorded in advance to the management apparatus 100 via the distribution apparatus.
On the other hand, the management apparatus 100 indicated in an area different from a room of the art museum shown in FIG. 1 is capable of communicating with the gateway via LAN, etc., and collects the location information and the attribute information transmitted by the wireless terminal 200. When the location information transmitted by the wireless terminal 200 indicates a location which is the same as (or near) the exhibit, the management apparatus 100 can instruct the output equipment 500 to output the content in accordance with the attribute information of the wireless terminal 200. For example, in the case where a wireless terminal 200 possessed by an elderly person is located near a certain exhibit, the management apparatus 100 selects content which uses bigger letters or content whose audio reproduction speed is slower and causes the output equipment 500 to output the content.
In this way, the content selection system 1 in an embodiment of the present invention can collect location information and attribute information of visitors through, for example, the distribution apparatus installed on the ceiling indoors.
FIG. 2 shows the gateway 400, the distribution apparatus 300 and the wireless terminal 200 which form the wireless network in FIG. 1 and are extracted from FIG. 1. For example, in the case where the wireless network is configured by ZigBee, the gateway 400 may function as a ZigBee coordinator which activates and manages the wireless network. Also, the distribution apparatus 300 may function as a ZigBee router which functions as a relay node, and the wireless terminal 200 may function as a ZigBee end device which transmits data.

The reception unit 105, which is realized by processes of the CPU 11 and NIC 15 shown in FIG. 3, receives identification information, location information and attribute information transmitted by the wireless terminal 200 via the distribution apparatus 300 (and the gateway 400). The received location information, together with the identification information, is stored in the location information storage unit 103, and the attribute information is, together with the identification information, stored in the attribute information storage unit 104.
The determination unit 106, which is realized by processes of the CPU 11 shown in FIG. 3, using the location information of the wireless terminal 200 as a key, searches through the exhibit information stored in the exhibit information storage unit 101, and determines whether there is an exhibit having the same location information. The determination unit 106, upon determining that there is an exhibit that has the same location information as the wireless terminal 200, passes the name of the exhibit and the identification information of the wireless terminal to the selection unit 107.
The selection unit 107, which is realized by processes of the CPU 11 shown in FIG. 3, upon receiving the name of the exhibit and the identification of the wireless terminal from the determination unit 106, reads the attribute information stored in the attribute information storage unit 104, and, using the received identification information of the wireless terminal as a key, identifies the corresponding attribute information. Also, the selection unit 107, using the received name of the exhibit as a key, identifies the corresponding Content ID and information of various conditions of age, gender, or the like. Then, the selection unit 107 identifies a Content ID with a condition satisfied by the identified attribute information and passes the Content ID to the output instruction unit 108.
A specific example of a process of the selection unit 107 will be described in which, using the identified attribute information, a Content ID which has a condition satisfied by the identified attributes is identified. For example, in the case where the identified attribute information (FIG. 10) includes “Y” for an item “color blind”, “blind”, “hearing loss”, or “perception of light”, the selection unit 107 may select content whose content information (FIG. 8) includes “Y” for one of the above items. Also, the selection unit 107 may select content whose content information includes the same information for items “gender”, “nationality”, “birthplace” and “occupation” as the information included in the attribute information. Also, the selection unit 107 may select content whose content information includes the same values for attribute items “age” and “visual acuity” included in the attribute information.
For example, it is assumed that the selection unit 107 receives attribute information represented by the identification information “012345672002” and the name of the exhibit “Drawing 2” (refer to FIG. 8 and FIG. 10). As the information of the item “blind” of the attribute information is “Y”, the selection unit 107 identifies content IDs “pic2_soundonly_jp” and “pic2_soundonly_eng” whose corresponding item is “Y”. Further, as the information of the item “nationality” of the attribute information is “US”, the selection unit 107 identifies the content ID “pic2_soundonly_eng”.
Also, referring to other example for the description, it is assumed that the selection unit 107 receives attribute information represented by the identification information “012345672001” and the name of the exhibit “Drawing 1” (refer to FIG. 8 and FIG. 10). As the information of the item “visual acuity” is “0.2”, the selection unit 107 identifies the content ID “pic1_jp_large” whose corresponding item is “less than 0.3”.
The selection unit 107 can identify a content ID of content by referring to identified attribute information and conditions indicated by the content information in any way not limited to the way described above. It should be noted that the further specific examples of content selection by the selection unit 107 will be described in section 5 herein.
The output instruction unit 108, which is realized by processes of the CPU 11 and the NIC 15, instructs the output equipment 500 to output the content corresponding to the content ID received from the selection unit 107. It should be noted that the output instruction unit 108 may transmit the content itself to the output equipment 500 or transmit information such as a file name which identifies the content to the output equipment 500.
By using the function described above, the content selection system 1 according to the present embodiment can select appropriate content according to the attributes of the visitor near the exhibit and output the content.
4. OPERATION EXAMPLES
Next, referring to FIG. 13 through FIG. 15, the operation examples of the content selection system 1 according to an embodiment of the present invention will be described. In the following, the description will be divided into a “location information and attribute information obtaining process” and a “content selection process” of the wireless terminal in the content selection system 1.
(4.1 Location Information and Attribute Information Obtaining Process)
First, FIG. 13 shows a sequence diagram of a process in which the management apparatus 100 in the present embodiment obtains location information and attribute information of the wireless terminal 200 through the wireless network. Here, the description will be provided assuming that the location information distributed by the distribution apparatus 300 includes, as shown as an example in FIG. 11, latitude “35.46100”, longitude “139.38090”, floor “1” and building number “2” and the identification information of the wireless terminal 200 is “012345672001”. It should be noted that it is assumed that the wireless terminal 200 stores in advance attribute information shown in FIG. 12.
Then, the location information distribution unit 303 of the distribution apparatus 300 reads the location information stored in the location information storage unit 301 (latitude “35.46100”, longitude “139.38090”, floor “1” and building number “2”) (step S101). Then, the location information distribution unit 303 distributes the positioning signal including the location information read in step S101 to wireless terminals within the predetermined range (step S102).
Then, the location information obtaining unit 205 of the wireless terminal 200 within the broadcast range of the positional signal obtains location information from the received positioning information and stores the location information in the location information storage unit 203 (step S103).
Then, the transmission unit 206 reads the identification information “012345672001” stored in the identification information storage unit 203 (step S104). Also, the transmission unit 206 reads the location information (latitude “35.46100”, longitude “139.38090”, floor “1” and building number “2”) stored in the location information storage unit 203 (step S105). Further, the transmission unit 206 reads the attribute information stored in the attribute information storage unit 201 (refer to FIG. 12) (step S106). Then, the transmission unit 206 transmits the read identification information, location information and attribute information to the distribution apparatus 300 (step S107).
The relay unit 302 of the distribution apparatus 300 receives the identification information, the location information and the attribute information transmitted by the wireless terminal 200 and transmits these pieces of information to the management apparatus 100 through the gateway (step S108).
The reception unit 105 of the management apparatus 100 receives the identification information, the location information and the attribute information transmitted by the wireless terminal 200 via the distribution apparatus 300 and stores the received location information together with the identification information in the location information storage unit 103 (step S109, refer to FIG. 9). It should be noted that only the information of latitude, longitude and floor is stored. Also, the reception unit 105 stores the received attribute information together with the identification information in the attribute information storage unit 104 (step S110, refer to FIG. 10).
With the process described above, the management apparatus 100 in the present embodiment can obtain the location information indicating the current location of the wireless terminal 200 and the attribute information associated with the wireless terminal 100.
(4.2 Content Selection Process (Process Flow))
Next, referring to FIG. 14, the process flow of the content selection process of the management apparatus 100 in the present embodiment will be described.
First, the determination unit 106 of the management apparatus 100 reads exhibit information stored in the exhibit information storage unit 101 (step S201, refer to FIG. 7). Then, the determination unit 106 reads the location information of each of the wireless terminals stored in the location information storage unit 103 (step S202, refer to FIG. 9). Then, the determination unit 106 compares the location information included in the exhibit information and the location information of each of the wireless terminals (step S203).
The determination unit 106 determines whether there is a wireless terminal whose location information coincides with the location information of some exhibit included in the exhibit information (step S204). Then, in the case where it is determined that there is a wireless terminal whose location information coincides with the location information of some exhibit (YES for step S204), the selection unit 107 reads the attribute information (FIG. 10) (step S205). Then, the selection unit 107 identifies the attribute information associated with the identification of the wireless terminal (step S206).
On the other hand, in step S204, in the case where there is no wireless terminal whose location information coincides with the location information of some exhibit (NO for step S204), the flow returns to step S201, and after a predetermined time elapses, the determination unit 106 reads the exhibit information again.
After step S206, the selection unit 107 reads the content information (FIG. 8) (step S207). Then, using the name of the exhibit whose location information has coincided with the location information of a wireless terminal in step S204, the selection unit 107 searches through the content information and identifies the target content ID (step S208). Then, the selection unit 107 selects the content ID of the content whose condition is satisfied by the attribute information identified in step S206 (step S209). Then, the output instruction unit 108 instructs the output equipment to output the content corresponding to the selected content ID (step S210).
With the process described above, the management apparatus 100 in the present embodiment can output the content in accordance with the attributes of the visitor who possesses the wireless terminal near the exhibit.
(4.3 Content Selection Process (Operation Examples))
Next, referring to FIG. 15, the operation examples of the content selection process of the management apparatus 100 in the present embodiment will be described.
First, the determination unit 106 of the management apparatus 100 reads the exhibit information stored in the exhibit information storage unit 101 (step S301). Then, the determination unit 106 reads location information of each of the wireless terminals stored in the location information storage unit 103 (step S302, refer to FIG. 9). Then, the determination unit 106 compares the location information of the exhibit included in the exhibit information (refer to FIG. 7) with the location information of each of the wireless terminals (refer to FIG. 9) (step S303). Then, the determination unit 106 determines that the location information of the wireless terminal (identification information “012345672001”) coincides with the location information (latitude “35.46100”, longitude “139.38090”, floor “1”) of the exhibit with the name of exhibit “drawing 1” (step S303). Then, the determination unit 106 passes the name of exhibit “drawing 1” and the identification information of the wireless terminal “012345672001” to the selection unit 107.
The selection unit 107 of the management apparatus 100 reads the attribute information from the attribute information storage unit 104 (step S305). Then, the selection unit 107 identifies the attribute information (“age” is “25”, “gender” is “M”, “nationality” is “JP”, “birthplace” is “Yokohama”, “occupation” is “IT”, “visual acuity” is “0.2”, “color blind”, “blind”, “hearing loss” and “perception of light” are all “N”) corresponding to the identification “012345672001” received at step S304 (step S306).
Then, the selection unit 107 of the management apparatus 100 reads the content information from the content information storage unit 102 (step S307). Then, the selection unit 107 identifies content IDs (“pic1_jp_default”, “pic1_jp_large” and “pic1_us”) of content corresponding to the name of exhibit “drawing 1” received at step S304 (step S308). Then, the selection unit 107 selects the content whose condition matches the read attribute information (step S309). Here, as the item of “visual acuity” is “0.2” in the attribute information associated with the identification information “012345672001”, the content ID “pic1_jp_large” is identified. Then, the selection unit 107 transmits the identified content ID to the output instruction unit 108 (step S310).
Then, the output instruction unit 108 instructs the output equipment 500 to output the content which has the transmitted content ID (step S311). It should be noted that the content IDs are associated with the entities of the content in advance by a table or the like (not shown).
With the operations described above, the management apparatus 100 in the present embodiment can output the content in accordance with the attributes of the visitor who appreciates the exhibit by dynamically switching the content.
5. SPECIFIC EXAMPLES OF CONTENT SELECTION
