Abstract

PROBLEM TO BE SOLVED: To achieve easy access to software intended to be used in an information processing terminal.SOLUTION: An information distribution device 100 detects existence of a plurality of information processing terminals T with an attribute "conference room A" showing the same place. Next, the information distribution device 100 estimates that a context of the plurality of information processing terminals T is "in conference". Then, the information distribution device 100 requests the plurality of information processing terminals T to display a common application corresponding to the context "in conference" on screens. Since the information distribution device 100 estimates the context based on the attributes of the plurality of information processing terminals T in this manner, the information distribution device 100 can estimate a context that is difficult to estimate only from an attribute of one information processing terminal T. Thus, the information distribution device 100 can provide easy access to software to be used for a user of the information processing terminal T.

The function is realized by executing the function or by the I / F 309.

  The storage unit 1301 has a function of storing, for each attribute, a context for specifying software specified by an icon or a character string on the display screen of the terminal. Here, the terminal is the information processing terminal T described above. The display screen is, for example, the display 1204 described above. The software is, for example, the above-described application. The attribute is, for example, the location or situation of the information processing terminal T determined from the sensing information described above or a combination of the sensing information described above. The context is, for example, the state of the information processing terminal T when a plurality of information processing terminals T exist with the same attribute. Specifically, for example, the attributes include an attribute for specifying a place and an attribute for specifying a situation at the place. More specifically, for example, “conference room A” is given as an attribute for specifying a place. In addition, “conference room A: lighting on” is given as an attribute for specifying the situation in the place.

  Specifically, for example, the storage unit 1301 stores “conference room A: in meeting” as a context when there are a plurality of information processing terminals T with the attribute “conference room A” indicating the place. Specifically, for example, the storage unit 1301 has “conference room A: in meeting” as a context when there is a plurality of information processing terminals T with the attribute “conference room A: lighting on” that identifies the situation at the place. Is memorized. Thereby, the storage unit 1301 can store an index for the information distribution apparatus 100 to specify the context of the information processing terminal T. By storing the context in association with the attribute specifying the situation in the place, the context of the information processing terminal T can be stored in a more detailed manner.

  The detection unit 1302 has a function of detecting the presence of a plurality of terminals with any one of the plurality of attributes. Specifically, for example, the detection unit 1302 receives the SSID “00-AB-CD-01” of the wireless LAN 110 as sensing information from a plurality of information processing terminals T, and refers to the location DB 103 to thereby obtain a plurality of information. The attribute “meeting room A” indicating the location of the processing terminal T is specified. Then, the detection unit 1302 detects the presence of a plurality of information processing terminals T with the attribute “conference room A” indicating the place. Thereby, the detection unit 1302 can detect a plurality of information processing terminals T existing with the same attribute.

Specifically, for example, the detection unit 1302 receives GPS coordinates as sensing information from a plurality of information processing terminals T, and refers to a DB that stores a location corresponding to the range of the GPS coordinates, thereby The attribute “conference room A” indicating the location of the information processing terminal T may be specified.
For example, in this case, since the GPS cannot accurately grasp the indoor location, the conference room in another outdoor building is specified as the attribute of the information processing terminal T. Specifically, for example, the detection unit 1302 receives the identifier of its own terminal as sensing information from the plurality of information processing terminals T via the infrared receiver provided at the place, so that the infrared receiver is The number of information processing terminals T existing in the attribute “conference room A” indicating the provided location may be detected.

  Specifically, for example, the detection unit 1302 receives the SSID “00-AB-CD-01” of the wireless LAN 110 as the sensing information from the plurality of information processing terminals T, and refers to the location DB 103, thereby The location “conference room A” of the information processing terminal T is specified. Furthermore, the detection unit 1302 receives sensing information from the environmental sensor 200 in the identified place “conference room A”, acquires the illuminance in “conference room A” with reference to the environmental sensor type DB, and “conference room A” The attribute “meeting room A: lighting” may be specified. In addition, when identifying the attribute that identifies the situation at the location, the detection unit 1302 receives time information, the volume at the location received from the environmental sensor 200, the illuminance at the location, or the door installed at the location. You may refer to an open / close state.

  The detection unit 1302 has a function of detecting the presence of a plurality of terminals with the same attribute received by the reception unit 1305 among the plurality of attributes. Specifically, for example, the detection unit 1302 detects that there are a plurality of information processing terminals T in the same attribute “conference room A” received by the reception unit 1305. Thereby, the detection unit 1302 can detect a plurality of information processing terminals T existing with the same attribute. The detection result is stored in a storage area such as the RAM 303, the magnetic disk 305, and the optical disk 307.

  The extraction unit 1303 has a function of extracting, from the storage unit 1301, a context corresponding to any attribute for which a plurality of terminals are detected by the detection unit 1302. Specifically, for example, the detection unit 1302 extracts the context “Conference Room A: In Meeting” from the storage unit 1301 according to the attribute “Conference Room A” from which the plurality of information processing terminals T are detected. Thereby, the extraction unit 1303 can extract a context that identifies an application to be displayed on the screens of the plurality of information processing terminals T detected by the detection unit 1302. The extraction result is stored in a storage area such as the RAM 303, the magnetic disk 305, and the optical disk 307.

  The transmission unit 1304 has a function of transmitting the context extracted by the extraction unit 1303 to a plurality of terminals. Specifically, for example, the transmission unit 1304 transmits the context “conference room A: in meeting” extracted by the extraction unit 1303 to a plurality of information processing terminals T. Thereby, the transmission unit 1304 can notify a context common to the plurality of information processing terminals T. Then, the information processing terminal T can display an application corresponding to the notified context.

  The transmission unit 1304 has a function of transmitting the context extracted by the extraction unit 1303 and the software specified by the context extracted by the extraction unit 1303 to a plurality of terminals. Specifically, for example, the transmission unit 1304 includes a plurality of context applications “conference room A: in meeting” extracted by the extraction unit 1303 and a conference application identified by “conference room A: in meeting”. It transmits to the information processing terminal T. Thereby, the transmission unit 1304 can provide the application to the information processing terminal T when the information processing terminal T does not have the conference application. Then, the information processing terminal T can display an application corresponding to the notified context.

  The receiving unit 1305 has a function of receiving software identification information and context identification information specified by an icon or a character string selected by any one of the plurality of terminals. Here, the software identification information is, for example, the application ID described above. The context identification information is, for example, the context ID described above. Specifically, for example, the receiving unit 1305 receives from the information processing terminal T a context ID “002” indicating “Meeting room A: In meeting” and an application ID “002”. As a result, the receiving unit 1305 can receive the information specifying the context and the application designated by the user of the information processing terminal T. The received data is stored in a storage area such as the RAM 303, the magnetic disk 305, and the optical disk 307.

  The receiving unit 1305 has a function of receiving attributes from each of a plurality of terminals. Specifically, for example, when the information processing terminal T has a function of detecting the attribute of the own terminal, the reception unit 1305 receives the attribute detected by the information processing terminal T. For example, the reception unit 1305 receives the attribute “conference room A” indicating the location detected by the information processing terminal T.

  The specifying unit 1306 has a function of specifying a context corresponding to any attribute stored in the storage unit 1301 based on the context identification information received by the receiving unit 1305. Specifically, for example, the specifying unit 1306 specifies “conference room A: in meeting” from the context ID “002” received by the receiving unit 1305. Thereby, the specifying unit 1306 can specify the context specified by the user of the information processing terminal T.

  The update unit 1307 has a function of updating the context according to any attribute by adding the software identification information received by the receiving unit 1305 to the context corresponding to any attribute specified by the specifying unit 1306 Have Specifically, for example, the updating unit 1307 adds the application ID “002” received by the receiving unit 1305 to the application list of the context “Meeting room A: In meeting” specified by the specifying unit 1306. Thereby, the update unit 1307 can register the application specified by the user of the information processing terminal T in the application list.

  In addition, the update unit 1307 updates the context according to any attribute by deleting the software identification information received by the receiving unit 1305 from the context corresponding to any attribute specified by the specifying unit 1306. It has the function to do. Specifically, for example, the updating unit 1307 deletes the application ID “002” received by the receiving unit 1305 from the application list of the context “Conference room A: In meeting” specified by the specifying unit 1306. Thus, the update unit 1307 can delete the application specified by the user of the information processing terminal T from the application list.

(Functional configuration example of information processing terminal T)
Next, a functional configuration example of the information processing terminal T will be described with reference to FIG.

  FIG. 14 is a block diagram showing a functional configuration of the information processing terminal T. The information processing terminal T is configured to include a reception unit 1401, a search unit 1402, a display control unit 1403, a determination unit 1404, a selection unit 1405, a transmission unit 1406, and a detection unit 1407. Specifically, the functions (reception unit 1401 to detection unit 1407) serving as the control unit are, for example, by causing the CPU 1201 to execute a program stored in a storage device such as the ROM 1202 or the RAM 1203 illustrated in FIG. The function is realized by the I / F 1205.

  The information distribution apparatus 100 that communicates with the information processing terminal T stores, for each attribute, a context that specifies software specified by an icon or a character string on the display screen of the terminal, and a priority is set for each context. The first storage unit is provided. Here, the first storage unit is the storage unit 1301 illustrated in FIG.

  The receiving unit 1401 has a function of receiving a context corresponding to any attribute from the information distribution apparatus 100. Here, the attribute is, for example, the above-described sensing information or a combination of the above-described sensing information. The context is, for example, the state of the information processing terminal T when a plurality of information processing terminals T exist with the same attribute. Specifically, for example, the reception unit 1401 receives the context “Conference Room A: In Meeting” from the information distribution apparatus 100. Thereby, the receiving unit 1401 can receive the context which is the state of the information processing terminal T.

  The receiving unit 1401 has a function of receiving a context corresponding to the attribute transmitted by the transmitting unit 1406 from the information distribution apparatus 100. Specifically, for example, when the transmission unit 1406 transmits the attribute “conference room A” of the information processing terminal T to the information distribution device 100, the reception unit 1401 changes the attribute “conference room A” from the information distribution device 100. A corresponding “conference room A: in-conference” context is received. Thereby, the receiving unit 1401 can receive the context which is the state of the information processing terminal T.

  The search unit 1402 has a function of searching for software specified by the context received by the reception unit 1401 from the second storage unit that stores software groups. Here, the software is, for example, the above-described application. A 2nd memory | storage part is a memory | storage device which memorize | stores an application, for example, is ROM1202 of the information processing terminal T. FIG. Specifically, for example, the search unit 1402 searches the ROM 1202 for an application “meeting application” identified by the context “conference room A: in meeting” received by the receiving unit 1401. Accordingly, the search unit 1402 can search for an application corresponding to the context.

  In addition, when the determination unit 1404 determines that the second context should be prioritized, the search unit 1402 searches the second storage unit for the second software specified by the second context. It has the function to do. Specifically, for example, the search unit 1402 has a function of searching the ROM 1202 for an application identified by the context “conference room A: in meeting” determined to be prioritized by the determination unit 1404. Accordingly, the search unit 1402 can search for an application to be displayed on the display 1204 with higher priority and notify the display control unit 1403 of the search.

  The display control unit 1403 has a function of displaying an icon or a character string designating software searched for by the search unit 1402 in a specific display area in the hierarchized display area group. Here, the hierarchized display area group is, for example, a plurality of hierarchized desktop screens displayed on the display 1204 of the information processing terminal T. The specific display area is, for example, the top desktop screen. Specifically, for example, the display control unit 1403 displays the icon or character string of the application searched by the search unit 1402 on the top desktop screen of the information processing terminal T. Thereby, the display control unit 1403 can display an application corresponding to the context.

  At this time, the display control unit 1403 displays only the app icon or character string searched for by the search unit 1402 on the top desktop screen, and the app icon or character string displayed on the top desktop screen is the second. Display on subsequent layers. At this time, the display control unit 1403 displays the icon or character string of the application searched by the search unit 1402 on the top desktop screen, and displays the icon or character string of the application that cannot be displayed on the top desktop screen. It may be displayed on the second and subsequent layers.

  At this time, the display control unit 1403 saves the identifier for identifying the icon or character string of the application displayed on the top desktop screen in the RAM 1203, and stores the top desktop screen of the application searched by the search unit 1402. It may be replaced with an icon or a character string. Then, the display control unit 1403 may restore the icon or character string of the application displayed on the original desktop screen based on the identifier for identifying the icon or character string of the saved application.

  Here, it is assumed that the second context is received after the receiving unit 1401 receives the first context and displays the first icon or character string. In this case, the determination unit 1404 has a function of determining which should be prioritized based on the priority set for the first context and the priority set for the second context. Specifically, for example, the determination unit 1404 determines that the context “conference room A: in a meeting” has priority over the context “conference room A: in a break”. Accordingly, the determination unit 1404 can cause the search unit 1402 to search for an application corresponding to a context that should be prioritized.

  The selection unit 1405 has a function of accepting selection of any icon or character string from at least one of the icon group or character string group displayed in the display area group. Specifically, the selection unit 1405 causes the input device 1206 to select any icon or character string in at least one of the application icon group or character string group displayed on the top desktop screen of the display 1204. Accept the selection. Accordingly, the selection unit 1405 can accept an input of an application designated by the user of the information processing terminal T.

  The transmission unit 1406 has a function of transmitting software identification information and context identification information specified by any icon or character string selected by the selection unit 1405 to the information distribution apparatus 100. Specifically, for example, the transmission unit 1406 obtains an application ID that identifies the application of the icon or character string selected by the selection unit 1405 and a context ID that identifies the context specified by the user of the information processing terminal T. It transmits to the information distribution apparatus 100. Accordingly, the transmission unit 1406 can transmit the context ID and the application ID specified by the user of the information processing terminal T to the information distribution apparatus 100.

  The transmission unit 1406 has a function of transmitting the attribute detected by the detection unit 1407 to the information distribution apparatus 100. Specifically, the transmission unit 1406 transmits the attribute “conference room A” of the information processing terminal T detected by the detection unit 1407 to the information distribution apparatus 100. Thereby, the information processing terminal T can transmit the attribute detected by the own terminal to the information distribution apparatus 100.

  The detection unit 1407 has a function of detecting that any one of a plurality of attributes is met. Specifically, for example, the detection unit 1407 detects the GPS coordinates of the information processing terminal T, and detects the attribute “conference room A” indicating the location of the information processing terminal T. Accordingly, the detection unit 1407 can detect the attribute of the information processing terminal T.

(Processing details of context estimation processing)
Next, processing contents of context estimation processing by the information distribution apparatus 100 shown in FIG. 1 will be described with reference to FIG.

  FIG. 15 is a flowchart showing the processing contents of the context estimation processing by the information distribution apparatus 100. First, the CPU 301 determines whether sensing information has been received (step S1501). Here, when sensing information is not received (step S1501: No), CPU301 returns to step S1501 and waits for reception of sensing information.

  On the other hand, when sensing information is received (step S1501: Yes), the CPU 301 acquires sensing information of another information processing terminal T within 5 minutes (step S1502). Next, the CPU 301 determines whether or not there is an SSID identical to the SSID of the received sensing information (step S1503). Here, when there is no same SSID (step S1503: No), CPU301 complete | finishes a context estimation process.

  On the other hand, when there is the same SSID (step S1503: Yes), the CPU 301 determines whether or not the place corresponding to the SSID is a conference room (step S1504). If the location corresponding to the SSID is not a conference room (step S1504: No), the CPU 301 ends the context estimation process.

  On the other hand, when the location corresponding to the SSID is a conference room (step S1504: Yes), the CPU 301 generates a “meeting” context (step S1505) and ends the context estimation process. Thereby, the information distribution apparatus 100 can estimate the context of the information processing terminal T.

(Contents of information distribution processing)
Next, processing contents of the information distribution processing by the information distribution apparatus 100 illustrated in FIG. 1 will be described with reference to FIG. The information distribution process is a process for distributing information corresponding to the context estimated by the context estimation process.

  FIG. 16 is a flowchart showing the processing contents of information distribution processing by the information distribution apparatus 100. First, the CPU 301 acquires an application list corresponding to the context estimated by the context estimation process from the context-application group correspondence DB 107 (step S1601).

  Next, the CPU 301 compares the acquired application list with the transmitted application DB 108 (step S1602). Then, the CPU 301 determines whether or not all the applications in the acquired application list have been transmitted (step S1603).

  Here, when all the applications have been transmitted (step S1603: Yes), the CPU 301 transmits the estimated context to the information processing terminal T (step S1604). Then, the CPU 301 ends the information distribution process.

  On the other hand, when there is an application that has not been transmitted (step S1603: No), the CPU 301 transmits the estimated context and the untransmitted application to the information processing terminal T (step S1605). Then, the CPU 301 ends the information distribution process. Thereby, the information distribution apparatus 100 can transmit information corresponding to the context of the information processing terminal T to the information processing terminal T.

(Processing content of screen display processing)
Next, processing contents of the screen display processing by the information processing terminal T shown in FIG. 1 will be described with reference to FIG.

  FIG. 17 is a flowchart showing the processing content of the screen display processing by the information processing terminal T. First, the CPU 1201 determines whether or not information distributed from the information distribution apparatus 100 has been received (step S1701). If no information has been received (step S1701: NO), the CPU 1201 returns to step S1701 and waits for information reception.

  On the other hand, when information is received (step S1701: Yes), the CPU 1201 determines whether or not the received information is only a context (step S1702). Here, when the received information is only the context (step S1702: Yes), the CPU 1201 proceeds to step S1704.

  On the other hand, when the received information is a context and an application (step S1702: No), the CPU 1201 stores the received application in the ROM 1202 (step S1703). Next, the CPU 1201 outputs an application corresponding to the context to the display 1204 (step S1704). Then, the screen display process ends. Thereby, the information processing terminal T can display an application corresponding to the context of the terminal itself on the display 1204.

(Contents of saving of application execution state by information processing terminal T when screen display is changed)
Next, the contents of saving the application execution state by the information processing terminal T when changing the screen display based on the display request received from the information distribution apparatus 100 will be described with reference to FIG.

  FIG. 18 is an explanatory diagram showing the contents of saving the application execution state by the information processing terminal T when changing the display of the screen. (1) Here, the information processing terminal T activates the application by the operation of the user of the information processing terminal T. Here, the electronic book browsing application is activated and the contents of the electronic book are displayed on the screen.

  (2) Next, the information processing terminal T receives a display request for an application different from the application currently displayed on the screen from the information distribution apparatus 100. Here, a display request for the conference application is received.

  (3) Upon receiving the application display request, the information processing terminal T saves the current application execution state in the RAM 1203. Then, the information processing terminal T displays the application requested to be displayed on the screen.

  (4) Next, the information processing terminal T ends the display of the conference application. The display of the conference application is terminated, for example, when the information processing terminal T leaves the conference room A or when there is an operation by the user of the information processing terminal T.

  (5) When the information processing terminal T finishes displaying the conference application, the information processing terminal T returns the execution state of the original application based on the execution state of the application saved in the RAM 1203. Thereby, since the information processing terminal T automatically returns to the original screen after the display request is received from the information distribution apparatus 100 and the display is changed, the convenience of the user of the information processing terminal T is improved. it can.

(Processing content of the application execution status saving process)
Next, processing contents of the application execution state saving process by the information processing terminal T shown in FIG. 18 will be described with reference to FIG.

  FIG. 19 is a flowchart showing the processing contents of the application execution state saving process by the information processing terminal T. First, the CPU 1201 determines whether or not the information distributed from the information distribution apparatus 100 has been received (step S1901). If no information is received (step S1901: NO), the CPU 1201 returns to step S1901 and waits for information reception.

  On the other hand, when information is received (step S1901: Yes), the CPU 1201 determines whether or not the context included in the received information matches the current context (step S1902). If the current context matches the current context (step S1902: YES), the CPU 1201 ends the application execution state saving process.

  On the other hand, if the current context does not match (step S1902: NO), the CPU 1201 stores the current context and the execution state of the application in the RAM 1203 (step S1903). Next, the CPU 1201 outputs an application corresponding to the received context to the display 1204 (step S1904).

  Then, the CPU 1201 determines whether or not the displayed application has been executed (step S1905). If the execution of the application has not ended (step S1905: No), the CPU 1201 returns to step S1905 and waits for the end of execution of the application.

  On the other hand, when the execution of the application is completed (step S1905: Yes), the CPU 1201 refers to the context stored in the RAM 1203 and the execution state of the application (step S1906).

  Next, the CPU 1201 returns the execution state of the application to the state before changing the display on the display 1204 based on the referred context and the execution state of the application (step S1907). Then, the CPU 1201 ends the application execution state saving process.

  Thereby, the information processing terminal T changes the display on the display 1204 after saving the execution state of the application, and restores the execution state of the saved application later. Therefore, since the user of the information processing terminal T does not have to restart the application after the display on the display 1204 is changed, the effort of the user of the information processing terminal T is reduced.

(Contents of customization of application list corresponding to the context)
Next, content of customization of the application list corresponding to the context stored in the information distribution apparatus 100 by the user of the information processing terminal T will be described with reference to FIG.

  FIG. 20 is an explanatory diagram showing the contents of customization of the application list corresponding to the context. (1) First, the information distribution apparatus 100 transmits an application list corresponding to the context to the information processing terminal T. Here, the transmission of the application list by the information distribution apparatus 100 is performed, for example, when the information distribution apparatus 100 receives a request for an application list from the information processing terminal T. Further, for example, the information processing terminal T transmits an application list request to the information distribution apparatus 100 by an operation of the user of the information processing terminal T.

  (2) The information processing terminal T displays an application corresponding to the received application list on the screen. Then, the user of the information processing terminal T customizes the displayed application. For example, the photographing application is replaced with a mail application among the displayed applications. Thereby, in the information processing terminal T, the photographing application is deleted from the received application list, and the mail application is added to the received application list. Then, the user of the information processing terminal T inputs the end of customization.

  (3) When the information processing terminal T receives an input indicating completion of customization, the information processing terminal T transmits the customized application list to the information distribution apparatus 100.

  (4) Then, the information distribution apparatus 100 updates the contents of the context-application group correspondence DB 107 based on the received application list. Thereby, the information distribution apparatus 100 can transmit to the information processing terminal T an application list display request more in line with the request of the user of the information processing terminal T.

(Customization process details)
Next, with reference to FIG. 21, processing contents of the customization process of the application list corresponding to the context by the information processing terminal T illustrated in FIG. 20 will be described.

  FIG. 21 is a flowchart showing the processing contents of the customization process of the application list corresponding to the context by the information processing terminal T. First, the CPU 1201 determines whether or not an event for starting execution of customization has occurred (step S2101). If no event has occurred (step S2101: No), the CPU 1201 returns to step S2101 and waits for an event to occur.

  On the other hand, when an event occurs (step S2101: Yes), the CPU 1201 acquires an application list from the context-application group correspondence DB 107 included in the information distribution apparatus 100 (step S2102). Then, the CPU 1201 displays the acquired application list application on the display 1204 (step S2103).

  Next, the CPU 1201 determines whether or not the displayed application has been changed (step S2104). If the displayed application is not changed (step S2104: No), the CPU 1201 ends the customization process.

  On the other hand, when the displayed application is changed (step S2104: YES), the CPU 1201 stores an application list indicating the changed application in the RAM 1203 (step S2105).

  Next, the CPU 1201 transmits the application list stored in the RAM 1203 to the information distribution apparatus 100 (step S2106), and ends the customization process. As a result, the application changed by the user of the information processing terminal T is transmitted to the information distribution apparatus 100. Then, the information distribution apparatus 100 can update the application list with the received changed application. As a result, the application corresponding to the context distributed by the information distribution apparatus 100 becomes an application according to the request of the user of the information processing terminal T, and the convenience of the user of the information processing terminal T can be improved.

(Contents of information distribution by information distribution apparatus 100 when information processing terminal T performs attribute determination)
Next, the contents of information distribution by the information distribution apparatus 100 when the information processing terminal T performs attribute determination will be described with reference to FIG. In FIG. 22, the information processing terminal T determines an attribute indicating a location based on the GPS coordinates.

  FIG. 22 is an explanatory diagram illustrating the contents of information distribution by the information distribution apparatus 100 when the information processing terminal T performs attribute determination. (1) First, the information distribution apparatus 100 transmits to the information processing terminal T an attribute DB 2200 that stores a location corresponding to a range of GPS coordinates that is a criterion for attribute determination.

  (2) Then, the information processing terminal T acquires the GPS coordinates at regular intervals by the terminal sensor 1207 that acquires the GPS coordinates provided in the terminal, and compares it with the received attribute DB 2200.

  (3) Next, when the acquired GPS coordinates are included in the GPS coordinate range stored in the received attribute DB 2200, the information processing terminal T specifies the attribute of the own terminal as “conference room A”. . Then, the information processing terminal T transmits the specified attribute “conference room A” to the information distribution apparatus 100.

  (4) The information distribution apparatus 100 receives the attribute “conference room A” from the plurality of information processing terminals T. Then, the context of the plurality of information processing terminals T is estimated as “conference room A: in meeting”.

  (5) Next, the information distribution apparatus 100 refers to the DB 130 (combination of the application DB 106 and the context-application group correspondence DB 107) that stores the application corresponding to the context, and estimates the context “meeting room A: in meeting”. Extract apps that correspond to. Then, the information distribution apparatus 100 transmits an application display request corresponding to the extracted context to the plurality of information processing terminals T.

  As described above, the information processing terminal T determines the attribute of the terminal at regular intervals, so that the change in the attribute can be detected earlier than the information distribution apparatus 100 determines the attribute.

(Processing content of context estimation processing when information processing terminal T performs attribute determination)
Next, the processing content of the context estimation processing by the information distribution apparatus 100 when the information processing terminal T performs the attribute determination shown in FIG. 22 will be described with reference to FIG.

  FIG. 23 is a flowchart showing the processing contents of the context estimation processing performed by the information distribution apparatus 100 when the information processing terminal T performs attribute determination. First, the CPU 301 transmits the attribute DB 2200 to the information processing terminal T (step S2301).

  Next, the CPU 301 determines whether or not the attribute of the information processing terminal T has been received from the information processing terminal T (step S2302). If no attribute has been received (step S2302: NO), the CPU 301 returns to step S2302 and waits for the reception of the attribute.

  On the other hand, when the attribute is received (step S2302: Yes), the CPU 301 determines whether or not the attribute of the other information processing terminal T received within 5 minutes has the same attribute as the received attribute. (Step S2303). Here, when there is no same attribute (step S2303: No), CPU301 complete | finishes a context estimation process.

  On the other hand, when there is the same attribute (step S2303: Yes), the CPU 301 determines whether or not the received attribute is an attribute indicating a conference room (step S2304). If the attribute does not indicate a conference room (step S2304: NO), the CPU 301 ends the context estimation process.

  On the other hand, if the attribute indicates a conference room (step S2304: YES), the CPU 301 generates a “meeting” context (step S2305), and ends the context estimation process. Thereby, the information distribution apparatus 100 can estimate the context of the information processing terminal T.

  And the information delivery apparatus 100 delivers the information corresponding to the context estimated by the context estimation process shown in FIG. 23 to the information processing terminal T by the information delivery process shown in FIG. Thereby, the information distribution apparatus 100 can transmit information corresponding to the context of the information processing terminal T to the information processing terminal T.

(Processing contents of attribute determination process when information processing terminal T performs attribute determination)
Next, processing contents of the attribute determination process performed by the information processing terminal T when the information processing terminal T performs the attribute determination illustrated in FIG. 22 will be described with reference to FIG.

  FIG. 24 is a flowchart showing the processing contents of attribute determination processing by the information processing terminal T when the information processing terminal T performs attribute determination. First, the CPU 1201 determines whether or not the attribute DB 2200 has been received from the information distribution apparatus 100 (step S2401). If the attribute DB 2200 has not been received (step S2401: NO), the CPU 1201 returns to step S2401 and waits for the attribute DB 2200 to be received.

  On the other hand, when the attribute DB 2200 is received (step S2401: Yes), the CPU 1201 acquires GPS coordinates at regular intervals (step S2402). Then, the CPU 1201 determines whether or not the acquired GPS coordinates are included in the GPS coordinate range stored in the attribute DB 2200 (step S2403). If the acquired GPS coordinates are not included in the GPS coordinate range stored in the attribute DB 2200 (step S2403: NO), the CPU 1201 returns to step S2402.

  On the other hand, when the acquired GPS coordinates are included in the range of GPS coordinates stored in the attribute DB 2200 (step S2403: Yes), the CPU 1201 generates an attribute of the information processing terminal T based on the attribute DB 2200 ( Step S2404). Then, the CPU 1201 transmits the generated attribute to the information distribution apparatus 100 (step S2405), and ends the attribute determination process. Thereby, the information processing terminal T can determine the attribute of the information processing terminal T, and can transmit the detected attribute to the information distribution apparatus 100.

  Then, based on the attribute transmitted by the attribute determination process shown in FIG. 24, the information distribution apparatus 100 estimates the context of the information processing terminal T, and transmits information corresponding to the estimated context to the information processing terminal T. . With the screen display process illustrated in FIG. 17, the information processing terminal T can display an application corresponding to the context of the terminal itself on the display 1204.

  As described above, according to the information distribution apparatus 100, the information distribution method, and the information distribution program, since the context is estimated based on the attributes of the plurality of information processing terminals T, only the attribute of one information processing terminal T is used. It is possible to estimate a context that is difficult to judge from. For example, it is difficult to estimate whether the context of the information processing terminal T is “meeting” only with information that the attribute indicating the location of one information processing terminal T is “conference room A”. On the other hand, the information distribution apparatus 100 receives the attribute indicating the location from the plurality of information processing terminals T, and determines whether or not the plurality of information processing terminals T exist in the attribute “conference room A” indicating the location. Thus, it can be estimated whether the context of the information processing terminal T is “meeting”.

  In addition, the information distribution apparatus 100 further refers to the time information and the sensing information received from the environment sensor 200, so that there are a plurality of information processing terminals T with the attribute “meeting room A: lighting on” that identifies the situation in the place. Judge whether to do. Thereby, the information distribution apparatus 100 can estimate that the context in the case where there are a plurality of information processing terminals T with the attribute “conference room A: lighting off” is not “meeting”, for example. On the other hand, the information distribution apparatus 100 can estimate that the context in the case where there are a plurality of information processing terminals T with the attribute “conference room A: lighting on” is “in a meeting”. As described above, the information distribution apparatus 100 can estimate more various contexts by acquiring the attribute specifying the situation in the place.

  Thereby, the information distribution apparatus 100 can unify the display of the screens of the plurality of information processing terminals T having common attributes. For example, the same application can be presented to users of a plurality of information processing terminals T in a conference room to perform common work. In addition, for example, an application for guiding a tourist spot can be presented to users of a plurality of information processing terminals T arriving at the tourist spot to provide a common guide.

  As a result, the application used by the user of the information processing terminal T is displayed on the screen of the information processing terminal T in the context “meeting”, and the user of the information processing terminal T To be easily accessible. Therefore, the convenience of the user of the information processing terminal T can be improved. Further, by switching the display of the information processing terminal T according to the context as described above, even when the display range of the information processing terminal T is narrow, the user of the information processing terminal T feels inconvenient. Nothing will happen.

  Further, when changing the display of the screen, the information processing terminal T saves the execution state of the application before the change in the RAM 1203. Thereby, when the information processing terminal T returns to the original screen after receiving the display request from the information distribution apparatus 100 and changing the display, the information processing terminal T can return the execution state of the application to the original state. User convenience can be improved.

  Further, the information distribution apparatus 100 accepts customization of the application list from the information processing terminal T. As a result, the information distribution apparatus 100 can generate an application list more in line with the request of the user of the information processing terminal T and transmit an application display request to the information processing terminal T. Therefore, the application list application according to the user's request is displayed on the screen on the information processing terminal T, and the convenience of the user of the information processing terminal T can be improved.

  Further, when the information processing terminal T determines the attribute of the terminal at regular time intervals, the attribute change can be detected earlier than the information distribution apparatus 100 determines the attribute. Therefore, the display change of the screen of the information processing terminal T can be executed more quickly.

  The information distribution method and information processing method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. The information distribution program and the information processing program are recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and are executed by being read from the recording medium by the computer. The information distribution program and the information processing program may be distributed through a network such as the Internet.
