== First Embodiment ==
First, a first embodiment of the present invention will be described. FIG. 1 is a diagram illustrating a configuration example of a mobile terminal according to the first embodiment. The mobile terminal 10 is an information processing apparatus such as a mobile phone or a PDA (Personal Digital Assistance). The mobile terminal 10 is configured to be able to execute various applications. For example, the mobile terminal 10 can execute an application in which Japanese input is performed, such as an application for sending and receiving e-mails. The portable terminal 10 is configured as a facility information output device capable of presenting the name of a facility near the current position (reference point) of the portable terminal as a candidate for an input phrase when Japanese input is performed. ing. FIG. 1 shows a configuration related to the function of the portable terminal 10 as a facility information output device.

  As shown in FIG. 1, the mobile terminal 10 includes a communication unit 20, a position information acquisition unit 22, a position information storage unit 24, a facility information acquisition unit 26, a facility information storage unit 28, a direction information acquisition unit 30, and a direction information storage unit. 32, direction calculation unit 34, facility list generation unit 36, facility list storage unit 38, character input reception unit 40, dictionary storage unit 42, phrase determination unit 44, phrase rule storage unit 46, phrase candidate output unit 48, and control unit 50 is comprised. Each unit illustrated in FIG. 1 can be realized, for example, in the mobile terminal 10 by using a storage area such as a memory or a storage device, or by executing a program stored in the storage area.

  The communication unit 20 is for communicating with other information processing apparatuses such as a server on the Internet via a network such as a packet communication network of a mobile phone or the Internet. Used when done.

  The position information acquisition unit 22 is configured to acquire position information indicating the current position of the mobile terminal 10 and store it in the position information storage unit 24. For example, the position information acquisition unit 22 can include a GPS receiver that can determine the current position by receiving a signal from a GPS (Global Positioning System) satellite. Here, the position information may include information indicating the accuracy of the position in addition to information such as latitude and longitude. Note that the position information acquisition unit 22 can repeatedly acquire position information at predetermined intervals. The position information storage unit 24 stores position information so that the moving distance of the mobile terminal 10 can be determined. For example, the position information storage unit 24 may store a history of acquired position information. In addition, when position information of a position that is a predetermined distance or more away from the position indicated by the most recent position information stored in the position information storage unit 24 is acquired, the position information stored in the position information storage unit 24 is It may be updated.

  The facility information acquisition unit 26 refers to a facility information database in which facility information including facility position information indicating the position of the facility and facility attribute information indicating the attribute of the facility is stored, and is predetermined from the current position of the mobile terminal 10. The facility information of the facility within the range is acquired and stored in the facility information storage unit 28.

  The facility information database can be configured to be connected to a search server on the Internet, for example. And the facility information acquisition part 26 can acquire facility information by transmitting the search request | requirement containing the positional information on a present position with respect to a search server. That is, the reference to the facility information database is not limited to that directly performed by the mobile terminal 10, but may be indirect via a search server. The search request transmitted to the search server may include, in addition to the position information, an identifier of the mobile terminal 10 or the user, information specifying the genre of the facility, and the like. The search server can search for facility information in consideration of information other than position information.

  The facility location information includes information such as latitude and longitude indicating the location of the facility. The facility attribute information includes various information such as the name and address of the facility. Note that the facility information stored in the facility information storage unit 28 may be a part of a data item included in the facility information stored in the facility information database. In this case, the extraction of the data items stored in the facility information storage unit 28 may be performed by the search server or the facility information acquisition unit 26. The facility indicated by the facility information may include events such as events in addition to the facility itself. That is, information indicating the event holding position may be set in the facility position information, and information indicating the event name or the like may be set in the facility attribute information.

  The direction information acquisition unit 30 acquires direction information (reference direction information) indicating a reference direction that is the direction in which the mobile terminal 10 is facing, and stores the direction information in the direction information storage unit 32. This direction information can be acquired using a sensor such as an electronic compass. The direction information acquired in this way can be used to indicate the direction in which the user of the mobile terminal 10 is facing. Note that the direction information acquisition unit 30 can repeatedly acquire direction information at a predetermined interval. The direction information acquisition unit 30 may acquire direction information using a sensor other than the electronic compass. For example, the direction information acquisition unit 30 may acquire the direction information of the mobile terminal 10 based on the output of a sensor that can detect the moving direction and inclination of the mobile terminal 10.

  The direction calculation unit 34 calculates a facility direction that is a direction with the current position as a reference point for each facility indicated by the facility information stored in the facility information storage unit 28. FIG. 2 is a diagram illustrating a specific example of calculating the facility direction. FIG. 2 shows the current position X of the mobile terminal 10, the position of the facility A, and the position of the facility B. For example, the direction calculation unit 34 can calculate the facility direction based on the current position and the latitude / longitude of each facility based on the angle of each facility with north at the current position being 0 degrees.

  The facility list generation unit 36 generates a facility list in which the facility direction of each facility calculated by the direction calculation unit 34 is associated with the facility information, and stores the facility list in the facility list storage unit 38. Further, the facility list generation unit 36 sorts the facility list stored in the facility list storage unit 38 in priority order based on the difference (angle difference) between the reference direction of the mobile terminal 10 and the facility direction of each facility. . For example, the facility list generation unit 36 can sort the facilities so that the priority order of the facilities whose angle difference is less than a predetermined angle (less than ± n degrees) is high. For example, in the example shown in FIG. 2, the reference direction is 315 degrees, and the directions of facility A and facility B are 45 degrees and 300 degrees, respectively. Here, if the predetermined angle is ± 30 degrees, the facility B is located below the predetermined angle from the reference direction, and therefore the priority in sorting based on the angle difference is higher than the facility A, and the facility B, facility A facility list is generated in the order of A. Note that the facility list generation unit 36 can change the predetermined angle, which is a reference for the angle difference, according to the number of facilities and the facility density. For example, in an area where the number of facilities is small or the facility density is low, the predetermined angle may be increased. The information on the number of facilities and the facility density may be set in the header of facility information acquired by the facility information acquisition unit 26 or based on the facility information stored in the facility information storage unit 28. It is good also as the facility list production | generation part 36 calculating.

  Further, the facility list generation unit 36 can use not only the angle difference but also other information related to the facility such as the distance from the current position to the facility, the popularity of the facility, and the like as a sorting criterion. . The sort key based on the angle difference may be the highest order sort key or the second and subsequent sort keys. In addition, the facility list may be sorted by changing the storage order in the facility list storage unit 38, or information indicating the priority order may be given to the facility information. Further, instead of generating the facility list separately, the facility information stored in the facility information storage unit 28 may be used as the facility list by giving the facility direction.

  The character input receiving unit 40 receives character input from the user, and is used, for example, when inputting an e-mail or inputting a search keyword. FIG. 3 shows an example of a screen of an application such as e-mail. In FIG. 3, in a region 60 for inputting Japanese, such as the body of an e-mail, a character input by the user using the operation key of the mobile terminal 10 is received by the character input receiving unit 40. Further, the character input receiving unit 40 can output candidates to the area 62 when converting a phrase composed of the received characters into kanji or the like by referring to the dictionary storage unit 42.

  The phrase determination unit 44 predicts a phrase to be input next to the phrase input via the character input reception unit 40. Specifically, the phrase determination unit 44 predicts a phrase related to the input phrase based on the phrase rule stored in the phrase rule storage unit 46. For example, in the word rule, the relevance of a word that is likely to be input continuously is registered, and the word determination unit 44 outputs a list of word candidates based on such word rule. Can do. The phrase determination unit 44 can also update the phrase rules based on the phrases that the user has actually input continuously.

  Further, the phrase rule includes a rule for predicting whether or not the next input phrase is a phrase related to the facility, and the phrase determination unit 44 determines that the next input phrase is the current position. Determine the possibility of a phrase related to a nearby facility. For example, in the phrase rule, after the phrase “from now on”, it may be registered that there is a high possibility that the destination facility going forward is input. In this way, the phrase rule may be for predicting a related phrase to be input next based on a phrase such as “from now on”, and is not just a phrase but the context or date / time of the input sentence. For example, it may be for predicting a related phrase to be input next based on more complicated information.

  The phrase candidate output unit 48 outputs a candidate for the next input phrase based on the determination result in the phrase determination unit 44. The word candidates are, for example, a list in which a plurality of word candidates are arranged on the basis of priority, and are displayed in the area 62 shown in FIG. Specifically, when the phrase determination unit 44 determines that the next input phrase is a phrase related to a facility near the current position, the phrase candidate output unit 48 is stored in the facility list storage unit 38. The name of the facility indicated by the existing facility list can be output to the area 62 according to the priority set in the facility list. On the other hand, if the phrase determination unit 44 determines that the next input phrase is not a phrase related to the facility near the current position, the phrase candidate output unit 48 stores the phrase stored in the phrase rule storage unit 46. Word candidates predicted based on the rules can be output to the region 62. Further, the phrase candidate output 48 may also output a phrase candidate other than the facility when outputting the phrase candidate related to the facility. The facility list generation unit 36, the facility list storage unit 38, and the phrase candidate output unit 48 constitute a facility information output unit.

  The control unit 50 performs various types of control in the mobile terminal 10, and can perform, for example, activation and termination of various applications such as an e-mail application and a search application, and task control.

  FIG. 4 is a flowchart illustrating an example of processing when character input is performed on the mobile terminal 10. This process is executed when an application for inputting characters such as an e-mail application is started by the control unit 50.

  First, the control unit 50 confirms whether an application (character input application) in which character input is performed is activated (S401). When the character input application is activated (S401: Y), the subsequent processing is executed.

  The position information acquisition unit 22 acquires position information indicating the current position of the mobile terminal 10 based on a signal from a GPS satellite and stores the position information in the position information storage unit 24 (S402). Here, it is assumed that the history of position information in a certain period is stored in the position information storage unit 24. The facility information acquisition unit 26 refers to the position information stored in the position information storage unit 24 and confirms whether the mobile terminal 10 has moved a predetermined distance or more (n meters or more) from the previously measured position (S403). .

  If the vehicle has moved more than a predetermined distance (S403: Y), the facility information acquisition unit 26 searches the facility information database for facility information of facilities within a predetermined range from the current position based on the latest position information. And stored in the facility information storage unit 28 (S404). Then, the direction calculation unit 34 refers to the facility information stored in the facility information storage unit 28, and calculates the facility direction of each facility with the current position as a reference point (S405). Further, the facility list generation unit 36 generates a facility list by associating the facility information with the facility direction, and stores it in the facility list storage unit 38 (S406).

  Subsequently, the direction information acquisition unit 30 acquires the direction information indicating the reference direction of the mobile terminal 10 at the current position, for example, by acquiring the direction from the electronic compass, and stores the direction information in the direction information storage unit 32 (S407). The facility list generation unit 36 then determines the direction of the mobile terminal 10 at the current position (reference) based on the facility list stored in the facility list storage unit 38 and the direction information stored in the direction information storage unit 32. The facility list is sorted and stored in the facility list storage unit 38 based on the angle difference between the (direction) and the direction of each facility (facility direction) based on the current position (S408). For example, the facility list generation unit 36 can sort the facility list using the angle difference as the first sort key and the distance from the current position as the second sort key. Note that the order of the both may be changed, and another element can be added as a further sort key.

  The character input receiving unit 40 receives character input from the user and performs kana-kanji conversion with reference to the dictionary storage unit 42 (S409). Then, the phrase determination unit 44 predicts whether or not the next input phrase is a phrase related to a facility near the current position based on a phrase rule such as whether or not the input phrase is a specific keyword ( S410). When it is predicted that the next input phrase is not a facility-related phrase (S410: N), the phrase candidate output unit 48 causes the phrase determination unit 44 to follow the phrase rule stored in the phrase rule storage unit 46. The normal phrase candidate list to be generated is output to the phrase candidate display area (S411). On the other hand, when it is predicted that the next input phrase is a phrase related to the facility (S410: Y), the phrase candidate output unit 48 stores the facilities in the sorted facility list stored in the facility list storage unit 38. The name is output to the phrase candidate display area (S412).

  The character input receiving unit 40 determines whether or not there is an instruction to determine a phrase from the displayed phrase candidates (S413). If there is no instruction for determining a phrase from among the phrase candidates (S413: N), the process returns to the process of acquiring position information (S402) and the process is repeated. On the other hand, when an instruction to determine a phrase from the phrase candidates is given (S413: Y), the character input receiving unit 40 displays the determined phrase in the character input area (S414).

  The control unit 50 determines whether or not the termination of the character input application is instructed (S415). While the termination instruction is not performed (S415: N), the process returns to the process of acquiring the position information (S402). Is repeated. On the other hand, when a termination instruction for the character input application is given (S415: Y), the control unit 50 executes a termination process for the character input application (S416).

  Through such processing, when displaying the names of facilities near the current position as word candidates when inputting characters, the names of the facilities are sorted in accordance with the angular difference between the direction of the mobile terminal 10 and the direction of each facility. The name will be displayed. That is, as shown in FIG. 5, the phrase candidates are displayed in a state where the priority of the facilities in the hatched range in the direction in which the user is facing is high, so the operation for selecting the facility name from the phrase candidates It becomes possible to improve the property.

The facility list is sorted and stored in the facility list storage unit 224 based on the angle difference with the direction of each facility (facility direction) based on the current position of the mobile terminal 100 (S1209). Then, the facility information transmission unit 226 of the server 200 transmits the sorted facility information to the mobile terminal 100 (S1210).

  The facility information acquisition unit 110 of the mobile terminal 100 receives the facility information transmitted from the server 200 and stores it in the facility information storage unit 112 (S1211). And the facility information output part 114 of the portable terminal 100 displays the list of facility information on a display as shown, for example in FIG. 9 (S1212).

  The facility information acquisition unit 110 of the portable terminal 100 waits for a user input to select one facility from a plurality of facilities indicated by the facility information displayed in the list (S1213). When a user input for selecting a facility is performed (S1213: Y), the facility information acquisition unit 110 transmits selection information (search request) for acquiring detailed information of the selected facility to the server 200.

  The search request receiving unit 212 of the server 200 receives the selection information transmitted from the mobile terminal 100 (S1215). In the server 200, the facility information acquisition unit 216 acquires detailed information on the selected facility from the facility information database, and the facility information transmission unit 226 transmits the detailed information to the portable terminal 100 (S1216).

  The facility information acquisition unit 110 of the portable terminal 100 receives the detailed information transmitted from the server 200 and stores it in the facility information storage unit 112 (S1217). And the facility information output part 114 of the portable terminal 100 displays the detailed information of a facility on a display as shown, for example in FIG. 10 (S1218).

  The control unit 50 of the mobile terminal 100 determines whether or not the termination of the search application has been instructed (S1219). While the termination instruction has not been performed (S1219: N), the process of determining the input of the search key (S1202). ) And the process is repeated. On the other hand, when an instruction to end the search application is made (S1219: Y), the control unit 50 ends the process.

  When the search result of the nearest facility is displayed by such processing, the names of the facilities are displayed in the order sorted according to the angle difference between the direction of the portable terminal 100 and the direction of each facility. That is, as shown in FIG. 5, since the search result is displayed in a state where the priority of the facility in the hatched range in the direction in which the user is facing is high, the desired facility is selected from the search result. The operability can be improved.

  In the process illustrated in FIG. 12, the facility information acquisition unit 216 of the mobile terminal 100 may newly generate a search request and transmit it to the server 200 every time the direction of the mobile terminal 100 changes. Thereby, for example, when the user points the mobile terminal 100 in various directions at the current position, it is possible to know what kind of facility is in each direction. In addition, when the target facility is determined but the direction is unknown, it is also possible to know in which direction the facility is based on facility information that dynamically changes according to the direction of the mobile terminal 100. The facility information acquisition unit 216 may generate a search request when the direction of the mobile terminal 100 changes by a predetermined angle or more in order to prevent a large amount of search requests from being generated.

  In the second embodiment, the facility information is searched using the current position as a reference point. However, the reference point for the search may be other than the current position. For example, the position of the reference point and the reference direction at the reference point may be designated by user input on the mobile terminal 100. FIG. 13 shows an example of a user input screen for designating the position of the reference point and the reference direction. As shown in FIG. 13, for example, on the map displayed on the mobile terminal 100, the reference point and the direction from the reference point are input so that the position and reference direction of the reference point are designated. Can do. In this case, the facility information acquisition unit 216 generates a search request including the position information indicating the position of the reference point specified in this way and the direction information indicating the reference direction, and transmits the search request to the server 200. That's fine. As a result, it is possible to acquire a list of facilities in a priority order in which the direction at the reference point is taken into account for facilities near the reference point other than the current position.

  Note that this embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention can be changed / improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

  For example, in the present embodiment, the case where the horizontal direction is used as the reference direction that is the direction at the reference point has been described, but the reference direction is not limited to the horizontal direction and may include the vertical direction. When the vertical direction is used, for example, direction information indicating the vertical direction can be acquired by using a gyro sensor or the like. For example, if information indicating altitude is included in the reference point or the location information of the facility, the vertical direction can be calculated in addition to the horizontal direction as the facility direction that is the direction from the reference point to the facility. It becomes. As a result, the facility attribute information can be output in the priority order considering the vertical direction. Specifically, for example, when the mobile terminal is directed upward, it is possible to increase the priority of the facility on the floor above the floor where the user is currently located. Similarly, for example, when the mobile terminal is directed downward, it is possible to increase the priority of facilities on the floor below the floor where the user is currently located, such as an underground shopping center facility.

  Note that only the vertical direction may be used as the reference direction. In this case, for example, a reference direction indicating an upward / downward degree can be specified in accordance with the vertical direction to which the user terminal is directed. Then, the facility direction indicating the degree of upward / downward from the reference position to each facility is specified, and the facility attribute information is output in the priority order based on the difference (altitude difference) between the reference direction and the facility direction. be able to. Specifically, for example, when the user is on the first floor of a department store, the reference direction (for example, the third floor) is specified according to the direction in which the mobile terminal is directed, and the reference direction and the facility direction of each facility are specified. The facility attribute information can be output in a priority order based on a difference from the difference (for example, a difference from the first floor). Further, it may be possible to switch between the horizontal direction and the vertical direction as the reference direction by an operation on the mobile terminal.

  Further, for example, in the present embodiment, as shown in FIG. 3 and FIG. 9, the facility attribute information such as the name of the facility is displayed in a line according to the priority order. However, the display mode of the facility attribute information is as follows. However, the present invention is not limited to this, and it may be anything considering the priority order. For example, the facility attribute information may be displayed in a matrix form in which a plurality of columns are provided vertically and horizontally, or may be displayed three-dimensionally in the depth direction.

  In addition, for example, in this embodiment, the names of facilities are displayed in the order sorted according to the angle difference between the direction of the mobile terminal and the direction of each facility. It may be only the facility in the direction in which is directed. For example, as illustrated in FIG. 16A, only a facility whose angle difference from the mobile terminal is within a predetermined angle (for example, 30 degrees) may be displayed. Further, for example, as shown in FIG. 16B, after the peripheral area of the mobile terminal is divided into four equal parts every 90 degrees, the facility information in the area in the direction where the mobile terminal is directed is downloaded from the server. It is good also as displaying on a portable terminal.

  Further, for example, in this embodiment, the character input application is executed by the stand-alone method and the facility search application is executed by the server / client method. However, the character input application is executed by the server / client method and the facility The search application may be executed in a stand-alone manner.
