However, the configuration is not limited thereto, and for example, an ASIC (Application Specific Integrated Circuit) is specified. Each configuration shown in FIG. 3 may be realized by hardware such as an integrated circuit for use).

  Each configuration of the mobile communication terminal 100 described above is a configuration necessary for realizing the present invention, and other configurations required for a basic function and an additional function as the mobile communication terminal are as required. It shall be provided.

  The operation of mobile communication terminal 100 having such a configuration will be described below. In the present embodiment, an operation when position information is used among operations when the electronic dictionary function of the mobile communication terminal 100 is executed will be described.

(Embodiment 1)
First, an operation when the position information of the mobile communication terminal 100 acquired by the GPS unit 160 is used for the electronic dictionary function will be described as a first embodiment. Here, it is assumed that when a user carrying the mobile communication terminal 100 visits an unknown place such as a sightseeing spot, information about the location is searched by the electronic dictionary function of the mobile communication terminal 100. To do.

  The “electronic dictionary process (1)” executed in the mobile communication terminal 100 in this case will be described with reference to the flowchart shown in FIG. This electronic dictionary process (1) is started when the user of the mobile communication terminal 100 instructs the execution of the electronic dictionary function by operating the operation unit 130.

  When the process is started, the electronic dictionary processing unit 111 displays an “electronic dictionary menu screen” as shown in FIG. 5A on the display unit 140 (step S101). As shown in the figure, the electronic dictionary menu screen displays the operation mode of the electronic dictionary in a selectable manner. In the present embodiment, at least a menu screen including a “current position mode” for performing a dictionary search according to position information by the GPS function is displayed.

  The user of the mobile communication terminal 100 operates the operation unit 130 to select a desired mode. In this embodiment, since the operation of the electronic dictionary function using position information will be described, it is assumed here that “current position mode” is selected. Therefore, when a mode other than the “current position mode” is selected (step S102: No), this process ends.

  When “current position mode” is selected (step S102: Yes), the electronic dictionary processing unit 111 displays a “search range designation screen” as shown in FIG. 5B on the display unit 140 (step S103). . This search range designation screen is a screen for allowing the user to designate the scale of the range centering on the current position of the mobile communication terminal 100. For example, “within 1 km from the current position”, “within 10 km from the current position” ”,“ 100 km from current position ”, etc. are displayed.

  The user of the mobile communication terminal 100 operates the operation unit 130 to specify the desired search range size. For example, when the user of the mobile communication terminal 100 comes to a tourist spot, if the user wants to examine the tourist spot, the search range is specified to be relatively narrow. On the other hand, for example, when it is desired to examine information about the entire area where the tourist spot is located, the search range is specified to be relatively wide.

  When the size of the search range is designated (step S104: Yes), the electronic dictionary processing unit 111 notifies the position information acquisition unit 112 of the size of the search range designated on the search range designation screen, and the mobile communication terminal The position information acquisition unit 112 is instructed to acquire position information indicating the current position of 100. The position information acquisition unit 112 controls the GPS unit 160 in accordance with an instruction from the electronic dictionary processing unit 111, and acquires position information (latitude and longitude information) indicating the current position of the mobile communication terminal 100 measured by the GPS unit 160. Obtain (step S105).

  When the position information indicating the current position of the mobile communication terminal 100 is acquired, the position information acquisition unit 112 defines a search range having a designated scale centered on the current position indicated by the acquired position information (step S106). ). Here, for example, the search range is defined by the approximate distance based on the latitude and longitude. That is, as shown in FIG. 6, the search range is a square range defined by latitude and longitude (coordinates) indicating a point separated by a specified distance in each of the east, west, north, and south directions from the current center position. . That is, this search range can be defined by a range of coordinate values indicating latitude and longitude. Here, since the distance for 1 degree latitude and longitude varies depending on the position on the earth, the exact distance cannot be uniquely defined, but the distance for 1 degree in Japan is about 100 to 110 km. For convenience, it is assumed that the search range is defined as a distance of one degree for each latitude and longitude of about 100 km.

  Such a search range is defined according to the size of the search range designated by the user on the search range designation screen (FIG. 5B). Here, since the distance for each latitude and longitude is about 100 km, when “within 100 km from the current position” is designated, the search is performed by the latitude and longitude that is ± 1 ° from each of the latitude and longitude of the current position. A range can be defined. Similarly, when “within 10 km from the current position” is specified, the search range is defined by the latitude and longitude that is ± 0.1 ° from each of the latitude and longitude of the current position, and “within 1 km from the current position” is specified. If it is, the search range is defined by the latitude and longitude of ± 0.01 ° from each of the latitude and longitude of the current position.

Here, as shown in FIG. 6, for example, the longitude of a position separated by a specified distance in the west direction from the longitude x _{0 of the} current position is x _W , and the longitude of a position separated by the specified distance in the east direction is x _E. In this case, the longitude range of the specified search range is x _W to x _E. Similarly, if the latitude of the current location is y _N from the latitude y ₀ and the latitude of the location separated by the specified distance in the north direction is y _S , the latitude of the specified search range range is y _N ~y _S of. As described above, the position information acquisition unit 112 uses the current position of the mobile communication terminal 100 acquired by the operation of the GPS unit 160 as a reference and sets the search range having a scale desired by the user to the coordinate value indicating the latitude and longitude. It is specified by the range.

  Note that this method is an example of the simplest method that can specify a search range of a designated scale from the latitude and longitude (coordinates) of the acquired current position. As long as the latitude and longitude (coordinates) of the search range based on a more accurate distance can be defined using the mounted GPS function, the method may be applied instead of the method exemplified above.

  When a search range of a designated scale, that is, a coordinate range indicated by latitude and longitude is defined, the position information acquisition unit 112 notifies the dictionary data acquisition unit 113 of the specified coordinate range. The dictionary data acquisition unit 113 accesses the position information storage area 172 in response to the notification from the position information acquisition unit 112, and searches for a headword in which the position information included in the notified coordinate range is recorded (step S107). ).

  As described above, the position information storage area 172 stores the headword of the content related to the location and the position information (latitude and longitude) among the dictionary data registered in the dictionary data storage area 171. The dictionary data acquisition unit 113 searches for a headword in which position information that falls within the coordinate range notified from the position information acquisition unit 112 is recorded.

  When a headword associated with position information within the specified search range is searched (step S108: Yes), the dictionary data acquisition unit 113 notifies the electronic dictionary processing unit 111 of the searched headword. . In this case, the electronic dictionary processing unit 111 displays a “search result display screen” as shown in FIG. 7A on the display unit 140 in which the headwords notified from the dictionary data acquisition unit 113 are displayed in a selectable list. (Step S109).

  That is, based on the current position information obtained by the GPS function of the mobile communication terminal 100, information related to locations around the current position is automatically listed from the dictionary data of the electronic dictionary function. In this case, when the user of the mobile communication terminal 100 operates the operation unit 130 to select a desired entry word from the displayed search results (step S110: Yes), the electronic dictionary processing unit 111 The selected headword is notified to the dictionary data acquisition unit 113.

  The dictionary data acquisition unit 113 accesses the dictionary data storage area 171 in response to the notification from the electronic dictionary processing unit 111, acquires the explanation information associated with the notified entry word, and the electronic dictionary processing unit 111. To hand over. In this case, the electronic dictionary processing unit 111 causes the display unit 140 to display an “explanation information display screen” as shown in FIG. 7B, which displays the explanation information delivered from the dictionary data acquisition unit 113 (step S111). ), The process is terminated.

  If there is no headword associated with the position information within the specified search range in the position information storage area 172 (step S108: No), the process ends.

  As described above, when the “electronic dictionary processing (1)” according to the present embodiment is executed, the location is determined based on the current position information acquired by the GPS function of the mobile communication terminal 100. Is automatically obtained from the electronic dictionary. Therefore, the user of the mobile communication terminal 100 can easily obtain information related to the place where the user is located without inputting a search phrase or the like in the electronic dictionary. Thereby, for example, in an unknown place such as a travel destination, when it is desired to comprehensively obtain information related to the place, it can be easily obtained only by acquiring the current position information.

  In addition, since the search range can be specified by the user, information search according to the purpose can be easily performed.

  In the present embodiment, GPS is used as a method for acquiring current position information. However, as long as information indicating the current position of the mobile communication terminal 100 can be obtained, the method is arbitrary. For example, in the case of a mobile communication terminal, since the position registration operation is performed, the mobile communication terminal periodically obtains position information of neighboring base stations. Since the position of the neighboring base station can be regarded as almost the same as the position of the mobile communication terminal, the position information indicating the position (latitude and longitude) of the neighboring base station is used as the current position information of the mobile communication terminal. be able to. In this case, the position information acquisition unit 112 controls the communication control unit 120 to perform a position registration operation, whereby position information based on the position registration can be acquired. According to such a configuration, the above-described effects can be obtained even with a mobile communication terminal not equipped with a GPS function.

(Embodiment 2)
In the first embodiment, the electronic dictionary information related to the place is automatically presented based on the current position of the mobile communication terminal 100. However, when the user inputs a specific headword, Information retrieval based on position information associated with the headword may be performed.

  The “electronic dictionary process (2)” executed in the mobile communication terminal 100 in such a case will be described with reference to the flowchart shown in FIG. This “electronic dictionary processing (2)” is started when the user of the mobile communication terminal 100 operates the operation unit 130 to instruct execution of the electronic dictionary function.

  When the process is started, the electronic dictionary processing unit 111 displays an “electronic dictionary menu screen” as shown in FIG. 5A on the display unit 140 as in the first embodiment (step S201). In the present embodiment, a menu screen including at least a “keyword position search mode” is displayed as an operation mode of the electronic dictionary function.

  The user of the mobile communication terminal 100 operates the operation unit 130 to select a desired mode. In the present embodiment, the operation of the electronic dictionary function using the position information of the headword input by the user will be described. Therefore, the “headword position search mode” is selected here. Therefore, when a mode other than the “entry word position search mode” is selected (step S202: No), this process ends.

  When “entry word position search mode” is selected (step S202: Yes), as in the first embodiment, the electronic dictionary processing unit 111 displays a “search range designation screen” as shown in FIG. The information is displayed on the display unit 140 (step S203).

  As in the case of the first embodiment described above, the user of the mobile communication terminal 100 operates the operation unit 130 to specify the desired search range size.

  When the size of the search range is specified (step S204: Yes), the electronic dictionary processing unit 111 displays a “headword entry screen” for inputting a headword desired by the user as shown in FIG. This is displayed on the unit 140 (step S205).

  A user of the mobile communication terminal 100 operates the operation unit 130 and inputs a desired entry word. Here, for example, in an unknown place such as a travel destination, a phrase indicating the currently visited place (for example, a place name or a name of a tourist spot) is input as a headword.

  When the headword is input by the user's operation (step S206: Yes), the electronic dictionary processing unit 111 sends the size of the search range specified in step S204 to the position information acquisition unit 112 together with the input headword. Notice.

  The position information acquisition unit 112 accesses the position information storage area 172 and uses the position information associated with the headword notified from the electronic dictionary processing unit 111 as the current position information indicating the current position of the mobile communication terminal 100. (Step S207).

  When the current position information is acquired in this way, the same processing as Step S106 to Step S111 in the “electronic dictionary processing (1)” (FIG. 4) of Embodiment 1 is performed (Step S208).

  That is, the position information acquisition unit 112 defines a search range centered on the current position indicated by the position information acquired in step S207. In this case, as in the case of the first embodiment, based on the position information indicating the current position and the size of the search range notified from the electronic dictionary processing unit 111, the search range is determined by the range of coordinate values indicating latitude and longitude. Stipulate.

  When a search range of a designated scale, that is, a coordinate range indicated by latitude and longitude is defined, the position information acquisition unit 112 notifies the dictionary data acquisition unit 113 of the specified coordinate range. The dictionary data acquisition unit 113 accesses the location information storage area 172 in response to the notification from the location information acquisition unit 112, and the location information included in the notified coordinate range is obtained by the same operation as in the first embodiment. Search recorded headwords.

  When a headword associated with position information within the specified search range is searched, the dictionary data acquisition unit 113 notifies the electronic dictionary processing unit 111 of the headword searched. In this case, the electronic dictionary processing unit 111 causes the display unit 140 to display a “search result display screen” (FIG. 7A) similar to that in the first embodiment.

  That is, based on the position information associated with the headword input by the user of the mobile communication terminal 100, information on the location around the current position is automatically listed from the dictionary data of the electronic dictionary function. Is done. In this case, as in the case of the first embodiment, the “description information display screen” (FIG. 7B) for the headword selected by the user is displayed on the display unit 140, and the process ends.

  As described above, by executing the “electronic dictionary process (2)” according to the present embodiment, based on the position information of the headword input by the user of the mobile communication terminal 100, information related to the location Is automatically obtained from the electronic dictionary. Therefore, for example, if the user of the mobile communication terminal 100 inputs one name of a place where the user is currently visiting, the user can easily obtain related information about the vicinity.

  In addition, since the search range can be specified by the user, information search according to the purpose can be easily performed.

  In the present embodiment, the position information associated with the input headword is treated as the current position information. However, the location of the input phrase may not necessarily be the current position. That is, even if it is not the current position, if a word or the like indicating a place is input, other information related to the place can be easily obtained. Therefore, it is useful not only for collecting information in the area but also for obtaining information in advance at the time of planning before traveling, for example.

(Embodiment 3)
In the first embodiment, the position information is acquired by the current position recognition function (GPS function or position registration function) of the mobile communication terminal 100, and in the second embodiment, from the dictionary data stored in the mobile communication terminal 100. Although the position information is acquired, the position information may be acquired from the outside. In this case, for example, the position information can be acquired using an information service (web service) such as a map service provided via the Internet or the like.

  The “electronic dictionary process (3)” executed in the mobile communication terminal 100 in such a case will be described with reference to the flowchart shown in FIG. This “electronic dictionary processing (3)” is started when the user of the mobile communication terminal 100 instructs the execution of the electronic dictionary function by operating the operation unit 130.

  When the processing is started, the electronic dictionary processing unit 111 displays an “electronic dictionary menu screen” as shown in FIG. 5A on the display unit 140 as in the first embodiment (step S301). In the present embodiment, at least a menu screen including a “web cooperation mode” as an operation mode of the electronic dictionary function is displayed.

  The user of the mobile communication terminal 100 operates the operation unit 130 to select a desired mode. In the present embodiment, the operation of the electronic dictionary function using the position information provided by the web service will be described, and it is assumed here that the “web cooperation mode” is selected. Therefore, when a mode other than the “web cooperation mode” is selected (step S302: No), this process ends.

  When the “web cooperation mode” is selected (step S302: Yes), the electronic dictionary processing unit 111 displays a “search range designation screen” as shown in FIG. It is displayed on the display unit 140 (step S303). In this case, the user of the mobile communication terminal 100 operates the operation unit 130 to specify the desired search range size.

  When the scale of the search range is specified (step S304: Yes), the electronic dictionary processing unit 111 holds the specified content in the work area and also acquires position information acquisition in the web linkage mode to the position information acquisition unit 112. Instruct. The location information acquisition unit 112 controls the communication control unit 120 in response to the notification from the electronic dictionary processing unit 111 and connects to a website that provides location information.

  In this case, it is assumed that address information (for example, URL (Uniform Resource Locator)) indicating a website that provides the location information providing service is stored in advance in the location information storage area 172 and the location information acquisition unit 112. Controls the communication control unit 120 so that data communication with the website indicated by the address information is performed. Then, for example, a session with the website is established using a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol).

  The website accessed in this case is, for example, a website that provides a map image including position information indicating latitude and longitude, and is hereinafter referred to as a “service providing site”.

  When such a service providing site is accessed (step S305), it is necessary to specify the area of the map to be displayed. In this case, a desired map area is usually designated based on a postal code or an address. Therefore, web page data constituting a screen for searching a map by inputting a zip code or an address is transmitted from the service providing site to the mobile communication terminal 100. In this case, the electronic dictionary processing unit 111 processes the web page data received by the communication control unit 120, thereby displaying a “map search screen” as shown in FIG. 11A on the display unit 140 (step S306). .

  A user of the mobile communication terminal 100 operates the operation unit 130 and inputs a zip code, an address, and the like (hereinafter referred to as “map search information”) for searching a map. When the map search information is input, the electronic dictionary processing unit 111 instructs the position information acquisition unit 112 to transmit the input map search information to the service providing site.

  The location information acquisition unit 112 controls the communication control unit 120 in response to an instruction from the electronic dictionary processing unit 111, and transmits the input map search information through a continuous session with the service providing site (step S307). ).

  In this case, the service providing site searches for map image data corresponding to the map search information received from the mobile communication terminal 100, and displays web page data (hereinafter, referred to as the map image data) on the mobile communication terminal 100. "Map screen data") is transmitted to the mobile communication terminal 100. It is assumed that the map screen data transmitted by the service providing site includes identification information for specifying a map image to be displayed.

  When the communication control unit 120 of the mobile communication terminal 100 receives web page data, a map image is displayed on the display unit 140 by the processing of the electronic dictionary processing unit 111. Here, as shown in FIG. 11B, a “map display screen” in which a cursor that is moved by the operation of the operation unit 130 is displayed on the map image is displayed on the display unit 140 (step S308). The user of the mobile communication terminal 100 operates the cursor key constituting the operation unit 130 to move the cursor to a desired position on the map, and then performs an input operation for instructing determination.

  By this operation, the position on the map desired by the user of the mobile communication terminal 100 is designated. In this case (step S309: Yes), the electronic dictionary processing unit 111 identifies the coordinate value on the map image indicating the designated position, and the identified coordinate value (hereinafter referred to as “map coordinate data”) The position information acquisition unit 112 is notified of the identification information of the map image, and the acquisition of the position information (latitude / longitude information) of the position is instructed.

  In response to an instruction from the electronic dictionary processing unit 111, the position information acquisition unit 112 controls the communication control unit 120 to transmit the map image identification information and the map coordinate data to the service providing site to inquire about the position information. Perform (step S310).

  Here, in the service providing site that provides the map image, the map image data to be provided in the database or the like is accumulated, and the position information indicating the latitude and longitude on each map image corresponds to the coordinate value on the map image. It is assumed that it is recorded. In this case, the service providing site specifies the accumulated map image based on the identification information of the map image transmitted from the mobile communication terminal 100, and calculates the latitude and longitude corresponding to the inquired map coordinate data. The acquired position information is acquired and transmitted to the mobile communication terminal 100.

  In the mobile communication terminal 100, when the communication control unit 120 receives the position information transmitted from the service providing site, the communication information is input to the position information acquisition unit 112. Thereby, the position information acquisition unit 112 acquires position information indicating the latitude and longitude of the position designated by the user on the map image from the service providing site (step S311).

  When the position information is acquired in this way, the same processing as Step S106 to Step S111 in the “electronic dictionary processing (1)” of Embodiment 1 described above is performed (Step S312).

  That is, the position information acquisition unit 112 defines a search range centered on the current position indicated by the position information acquired in step S311. In this case, as in the case of the first embodiment, the search is performed by the range of coordinate values indicating the latitude and longitude based on the position information indicating the current position and the size of the search range held in the work area by the electronic dictionary processing unit 111. Define the range.

  When a search range of a designated scale, that is, a coordinate range indicated by latitude and longitude is defined, the position information acquisition unit 112 notifies the dictionary data acquisition unit 113 of the specified coordinate range. The dictionary data acquisition unit 113 accesses the location information storage area 172 in response to the notification from the location information acquisition unit 112, and the location information included in the notified coordinate range is obtained by the same operation as in the first embodiment. Search recorded headwords.

  When a headword associated with position information within the specified search range is searched, the dictionary data acquisition unit 113 notifies the electronic dictionary processing unit 111 of the headword searched. In this case, the electronic dictionary processing unit 111 causes the display unit 140 to display a “search result display screen” (FIG. 7A) similar to that in the first embodiment.

  That is, based on the position information of the desired location designated on the map image by the user of the mobile communication terminal 100, information on the location around the current location is automatically enumerated from the dictionary data of the electronic dictionary function. Is done. In this case, as in the case of the first embodiment, the “description information display screen” (FIG. 7B) for the headword selected by the user is displayed on the display unit 140, and the process ends.

  As described above, by executing the “electronic dictionary processing (3)” according to the present embodiment, information related to the place is automatically obtained from the electronic dictionary using the position information provided from the website or the like. To be acquired. Therefore, the user of the mobile communication terminal 100 can easily obtain related information about the vicinity just by intuitively specifying the location on the map screen.

  In addition, since the search range can be specified by the user, information search according to the purpose can be easily performed.

  In the present embodiment, the map information can be obtained from the service providing site. However, it is not always necessary to display the map image as long as the position information indicating the latitude and longitude can be acquired. In this case, for example, position information corresponding to the map search information input on the address input screen shown in FIG. 11A may be transmitted from the service providing site to the mobile communication terminal 100.

  As described above, by applying the present invention as described in the above embodiment, information related to a place can be easily obtained by the electronic dictionary function of an electronic device such as a mobile communication terminal.

  In other words, among the headwords recorded in the dictionary data used for the electronic dictionary function, the headword for the content related to the location is associated with the location information indicating the location, so it is related to the specified location. The headword to be selected can be automatically selected and presented.

  Here, when specifying the location, the position information indicating the current location of the apparatus is used, so that information related to the location where the user is present can be easily obtained by the electronic dictionary function. Thereby, for example, even in a place that is unknown to the user, such as a travel destination, information on the place can be easily obtained.

  In addition, since the headword and the position information are stored in association with each other, based on the position information of the headword input by the user, other headwords associated with the position information around the position are stored. It can also be automatically selected and presented. In this case, for example, if a word or the like indicating the current location of the user is input as an entry word in the electronic dictionary, the position information associated with the entry word can be used as position information indicating the current position. . In this case, if one word / phrase recognized by the user (for example, the name of a tourist spot or a building or the name of a place) is input, information about the surrounding area can be easily obtained. Moreover, since the input phrase does not have to relate to the current position, it is possible to easily acquire information relating to a remote location.

  In addition, for example, the location information can be specified using a service provided via the Internet or the like, so that the location information can be obtained in cooperation with a map providing service or a navigation service that is generally popular as a web service. Can be specified. In this case, information related to the place can be easily obtained from the electronic dictionary by an intuitive operation such as designating a desired place on the map image. In this case, the position information can be acquired even by inputting a zip code or an address. Therefore, when such information is already known, the information can be acquired efficiently.

  In these cases, the user can specify a search range centered on the specified position, so that the desired information can be efficiently acquired by specifying the search range according to the purpose of use. .
