For example, the control unit 10 acquires the remaining battery level from the remaining battery level detection unit 18 at a predetermined timing (for example, every hour), and records the acquired remaining battery level in a log.

  FIG. 2 (n) shows a log representing the history of weather in the user's residence. The log type of this log is “weather”. This log has two items, “date” and “weather”. The information of the item “date” indicates the date on which the weather was recorded. Information on the item “weather” indicates the weather condition. The control unit 10 of the terminal device 1 obtains weather information by accessing a predetermined website that provides weather information of the user's residence, for example, at a predetermined time, and records the weather information in a log together with the date.

  FIG. 2 (o) shows a log representing the temperature history in the user's residence. The log type of this log is “temperature”. This log has two items of “date” and “temperature”. The information of the item “date” indicates the date when the temperature is recorded. The information of the item “temperature” indicates the temperature of the day. The recorded temperature may be a maximum temperature, a minimum temperature, or an average temperature. Alternatively, the number of log items may be increased so that two or more of the highest temperature, the lowest temperature, and the average temperature can be recorded in the log. The control unit 10 of the terminal device 1 accesses a website that provides temperature information of the user's residence specified in advance at a predetermined time, acquires the temperature information, and records it in a log together with the date. In addition, when the terminal device 1 is equipped with the temperature sensor (not shown), you may acquire temperature (air temperature) from the temperature sensor.

  Examples of various logs stored in the log DB 114 are shown in FIGS. 2A to 2O. However, the logs that can be stored in the log DB 114 are not limited to these, and the log DB 114 stores logs of different log types. May be included. For example, a log indicating a change history related to the setting state of the terminal measure 1 (manner mode on / off, lighting / extinguishing of the display unit 12, on / off of the vibration function, etc.) may be included. Further, the log DB 114 does not necessarily include all the logs shown in FIGS. Further, the items included in the log of each log type described above are not limited to those described above. For example, a log with the log type “music” may include items such as “composer”, “lyricist”, “genre”, etc., and a log with the log type “video” includes “director”, “screenplay” Or the like.

  As will be described in detail later, when the user inputs a character string, the control unit 10 searches the log DB 114 for a log related to the input character string, and displays information included in the searched log as an input candidate. 12 is displayed.

  The keyword DB 115 stores a keyword character string associated with the log type of each log stored in the log DB 114. The keyword DB 115 is used to specify a log (log type) related to the input character string. FIG. 3 shows an example of the keyword DB 115.

  As shown in FIG. 3, “here”, “one”, “bash”, “position”, and “location” are stored as keyword character strings for the log type “position”. Similarly, related keyword character strings are stored for other log types. The keyword character string is not limited to a plurality of characters, and may be a single character.

  When the user inputs a character string, the control unit 10 determines whether the keyword character string stored in the keyword DB 115 is included in the input character string or its conversion candidate. When the keyword character string 115 is included in the input character string or its conversion candidate, the control unit 10 determines that the log of the log type associated with the keyword character string is a log related to the input character string. In other words, the control unit 10 determines that there is a high possibility that the information included in the log includes information that the user desires to input.

  The input candidate setting DB 116 sets which items of information included in the log should be displayed as input candidates when displaying information included in the log related to the input character string as input candidates for the input character string. Remember. Specifically, the input candidate setting DB 116 has a display setting table 117 that stores, for each item, settings for whether or not to display as input candidates for each log type.

  FIG. 4 shows a display setting table for the log type “step count” shown in FIG. 2B as an example of the display setting table 117 included in the input candidate setting DB 116. The display setting table 117 shown in FIG. 4 has the log type “step count” for each log item (“date”, “step count”, “distance”, “walking time”, and “average walking speed”). And whether to display information as input candidates. Whether or not to display information as an input candidate may be set, for example, by setting a flag value that can take either 1 or 0 for each item (for example, “1” is Display indicates that display is to be performed, and “0” indicates that display is not performed.) Similarly, for other log types, the input candidate setting DB 116 has a display setting table 117 for setting whether to display information as input candidates for each item.

  Further, the display setting table 117 sets additional display information to be displayed together when displaying log item information as input candidates. The additional display information is, for example, the unit of information of each item (for example, “step” for the item “steps”, “km” for the item “distance”, “time” for the item “walking time”, and the item “average” It may be “km / h”) for “walking speed”. The additional display information is not limited to a unit, and may be other information such as an arbitrary icon or pictograph selected by the user.

  The keyword DB 115 shown in FIG. 3 and the input candidate setting DB 116 (display setting table 117) shown in FIG. 4 may be created by the provider of the terminal device 1 (for example, a mobile phone company) or by the user. May be. When provided by a communication service provider such as a mobile phone company, the user may download the keyword DB 115 and the input candidate setting DB 116 from a predetermined server of the communication service provider via a communication line. Alternatively, each time access is required without downloading, the keyword DB 115 and the input candidate setting DB 116 prepared on the server may be accessed to obtain necessary information. In that case, the same keyword DB 115 and / or input candidate setting DB 116 may be used in common by a plurality of users, and each of a plurality of users who commonly use the keyword DB 115 and / or input candidate setting DB 116 is stored in these databases. The content (for example, keyword character string) may be added or changed.

  FIG. 5 is a diagram illustrating an example of a functional configuration of the control unit 10 regarding input processing. As illustrated, the control unit 10 includes a log collection unit 101, a conversion unit 102, a character string comparison unit 103, a related log search unit 104, an input candidate detection unit 105, and a display control unit 106. The related log search unit 104 and the input candidate detection unit 105 are examples of the input candidate acquisition unit of the present invention. Each of these units is realized by the control unit 10 executing a program stored in the ROM of the control unit 10 or the storage unit 11. The log collection unit 101 records various types of information collected by the terminal device 1 in the log DB 114 as the various types of logs described above. As described above, the information recorded as a log is the operation of the terminal device 1 by the user (music or video playback, application use, incoming / outgoing phone call, mail transmission / reception, homepage browsing, search word is used. A history relating to search (etc.), a history relating to user behavior (walking, movement of places, etc.), and a history relating to surrounding conditions (temperature, weather, etc.) of the user (or terminal device 1) are included. A part or all of the functions of the log collection unit 101 may be realized by a log recording function of a plurality of applications such as a pedometer application and a browser application.

  When a character is input by the user operating the operation unit 13, the input character string (input character string) is supplied to the conversion unit 102, the character string comparison unit 103, and the display control unit 106. The display control unit 106 causes the display unit 12 to display the input character string. The conversion unit 102 refers to the dictionary DB 112, extracts conversion candidates corresponding to the input character string from the dictionary DB 112, and supplies them to the character string comparison unit 103 and the display control unit 106. The character string comparison unit 103 determines whether the keyword character string stored in the keyword DB 115 is included in the input character string or its conversion candidate. When a keyword character string is included in the input character string or its conversion candidate, the character string comparison unit 103 refers to the keyword DB 115 and acquires a log type related to the keyword character string. The log type acquired by the character string comparison unit 103 is sent to the related log search unit 104. When two or more keyword character strings are included in the input character string or the conversion candidate, the log type related to one of the keyword character strings may be sent to the related log search unit 104, or the keywords All log types related to the character string may be sent to the related log search unit 104.

  The related log search unit 104 accesses the log DB 114 using the log type supplied from the character string comparison unit 103, searches for a log corresponding to the log type, and acquires information included in the searched log. At this time, since the log usually includes a plurality of data sets, a predetermined number of data sets may be acquired in order from the newest one. Alternatively, a data set acquired between a predetermined time before the current time and the current time may be acquired. When there are two or more log types supplied from the character string comparison unit 103, information included in the log of each log type may be acquired. The acquired log information (data set) is sent to the input candidate detection unit 105 together with the log type.

  The input candidate detection unit 105 is set to access the input candidate setting DB 116 using the log type received from the related log search unit 104, refer to the display setting table 117 specified by the log type, and display as an input candidate. Identify the items that have Then, information on items set to be displayed as input candidates among the log information received from the related log search unit 104 is detected and supplied to the display control unit 106.

  The display control unit 106 causes the display unit 12 to display the input candidates supplied from the input candidate detection unit 105 together with the conversion candidates supplied from the conversion unit 102. Further, when the user operates the operation unit 13 to select one of the displayed input candidates and conversion candidates, the display control unit 106 causes the display unit 12 to display the selected candidate as a confirmed input.

2. Operation Next, the operation of the input process in the terminal device 1 configured as described above will be described with reference to FIGS. 6 is a flowchart showing the operation of the input process in the terminal device 1, and FIG. 7 is a schematic diagram showing an example of a screen displayed on the display unit 12 according to the input process.

  As shown in FIG. 6, when a character string is input by the user operating the operation unit 13 (step S1), the conversion unit 102 accesses the dictionary DB 112 to obtain conversion candidates corresponding to the input character string. (Step S2). Further, the display control unit 106 causes the display unit 12 to display the input character string and the conversion candidate acquired by the conversion unit 102 (step S3).

  FIG. 7A shows an example of a screen displayed in step S3 when the character string “Aritai” is input as an example. The display screen includes a status display area 121, a character input area 122, a conversion candidate display area 123, and an input candidate display area 124. In the status display area 121, for example, an icon indicating the reception status of radio waves from the base station of the mobile phone company and an icon indicating the remaining battery level of the terminal device 1 are displayed. The character input area 122 is an area in which the input character string is displayed. In this example, the character string “Aritai” is displayed. Here, the underline of the character string “has been” indicates a state before the input of the character string “has been” is confirmed. In the conversion candidate display area 123, conversion candidates for the input character string acquired by referring to the dictionary DB 112 are displayed. In the example shown in FIG. 7A, “alita”, “walked”, “alita”, and the like are displayed as conversion candidates for the input character string “alita”. In the conversion candidate display area 123, “Aritai” displayed at the top is displayed in white (or referred to as inverted display) to indicate that “Aritai” is designated as a conversion candidate. For example, the user can change the designated conversion candidate by operating a movement key (not shown) included in the operation key 132 of the operation unit 13. If there are a large number of conversion candidates and all of them cannot be displayed in the conversion candidate display area 123, they may be scrollable or displayed over a plurality of pages. When the user presses a confirmation key (not shown) in a state where a conversion candidate is specified, the conversion candidate is selected and displayed in the character input area 122. The input candidate display area 124 is an area in which log information considered to be related to the input character string among logs included in the log DB 114 is displayed as an input candidate. At the time of step S3, since the input candidate has not been acquired yet, the input candidate display area 124 is blank.

  Referring to FIG. 6 again, in step S4, the character string comparison unit 103 determines whether or not the keyword character string stored in the keyword DB 115 is included in the input character string or its conversion candidate. When a keyword character string is included in the input character string or its conversion candidate (step S4: YES), in step S5, the character string comparison unit 103 refers to the keyword DB 115 and acquires a log type related to the keyword character string. . If the keyword character string is not included in the input character string or its conversion candidate (step S4: NO), the process proceeds to step S9. In this example, the input character string “alit” includes the keyword character string “alit” and the keyword character string “alit” is associated with the log type “step count”. Acquires the log type “number of steps” as the log type related to the input character string “Ariita”. It should be noted that the conversion candidate of the input character string “alit” includes the character string “walked” and matches the character string “walked” which is one of the keyword character strings associated with the log type “step count”. . Therefore, even when the keyword character string does not include the character string “alita”, the log type “step count” is specified as the log type related to the input character string “alitai”.

  After step S5, in step S6, the related log search unit 104 accesses the log DB 114, searches the log corresponding to the log type acquired by the character string comparison unit 103 as a log related to the input character string, and performs a search. The information included in the log is sent to the input candidate detection unit 105 together with the log type. In this example, a log with the log type “step count” is searched, and all or part of the information included in the log is sent to the input candidate detection unit 105 together with the log type.

  Subsequently, in step S <b> 7, the input candidate detection unit 105 is set to be displayed as an input candidate in the corresponding display setting table 117 of the input candidate setting DB 116 out of the log information searched by the related log search unit 104. The item information is detected and sent to the display control unit 106. In this example, as shown in FIG. 4, in the display setting table 117 corresponding to the log type “step count”, the item “step count” and the item “walking distance” are set as items to be displayed as input candidates. The detection unit 105 detects information on the item “number of steps” and information on the item “walking distance” and sends the information to the display control unit 106. At that time, the input candidate detecting unit 105 adds the additional display information set for each item in the display setting table 117 (in this example, “step” for the item “steps” and “km” for the item “walking distance”). ) Are also sent to the display control unit 106. In step S8, the display control unit 106 adds the additional display information to the information detected in step S7, and causes the display unit 12 to display the input candidate.

  FIG. 7B shows an example of the display screen displayed in step S8. As shown in the figure, in this example, among the information included in the log with the log type “step count”, the item “step count” information and the item “walking distance” information are input candidates together with the additional display information. It is displayed in the display area 124. In this example, information (“15432 steps” and “10.5 km”) included in the newest data set is displayed at the top, and older information is displayed below. Further, based on the display priority of the item set in advance, the item “step count” information is displayed before the item “walking distance” information. Although only information corresponding to two data sets is displayed in FIG. 7B, the present invention is not limited to this, and information corresponding to more data sets may be displayed. Alternatively, for example, only information corresponding to the newest data set may be displayed. When there is a lot of information displayed in the input candidate display area 124, scroll display may be possible, or display may be performed over a plurality of pages.

  Referring to FIG. 6 again, in step S9, the user operates the movement key to specify either the conversion candidate displayed in the conversion candidate display area 123 or the input candidate displayed in the input candidate display area 124, Press the enter key to select the specified conversion candidate or input candidate. FIG. 7C shows a state in which the character string “15432 steps” displayed as an input candidate in the input candidate display area 124 is designated. In the figure, the designated input candidate “15432 steps” is displayed in white.

  When a conversion candidate or input candidate is selected by the user, in step S10, the display control unit 106 displays the selected conversion candidate or input candidate in the character input area 122 as a confirmed input. FIG. 7D shows a state where the input candidate “15432 steps” is selected by the user and displayed in the character input area 122. In the example shown in FIG. 7D, even when the input candidate “15432 steps” is selected and displayed in the character input area 122, the conversion candidate display area 123 and the input candidate display area 124 are displayed as they are. Accordingly, if the user selects a conversion candidate or input candidate displayed in this state, the selected conversion candidate or input candidate is input to the character input area 122 as a confirmed input following “15432 steps”. Is displayed. As another mode, when the input candidate “15432 steps” is selected and displayed in the character input area 122, the conversion candidate display area 123 and the input candidate display area 124 are closed, and a new character string is input. Accordingly, the conversion candidate display area 123 and the input candidate display area 124 may be displayed.

  Similar to the case where the character string “alitai” is input, for example, when the character string “1” or “bash” is input, the log type “position” is set as the log type related to the input character string. Information (for example, “Tokyo”) that is specified and set to be displayed as an input candidate by the corresponding display setting table 117 among the log items having the log type “position” shown in FIG. “Nihonbashi 1-2-9 in Chuo-ku, Tokyo” and “1-2-10 Nihonbashi Chuo-ku, Tokyo”) are displayed in the input candidate display area 124 as input candidates. When the character string “ongaku” is input, the log type “music” is specified as the log type related to the input character string, and the log item “log” shown in FIG. Among them, information (for example, “Jingle Bells” and “Various People”) set to be displayed as input candidates by the corresponding display setting table 117 is input candidate display area 124 as input candidates. Is displayed. When the character string “Eiga” is input, the log type “moving image” is specified as the log type related to the input character string, and the log type shown in FIG. Information (for example, “Legendary Speech” or “Rain Sound”) of items (for example, titles) set to be displayed as input candidates by the corresponding display setting table 117 is displayed as input candidates. Similarly, when “phone call” or “phone call” is specified as the log type related to the input character string, for example, information of the items “name” and “phone number” are displayed as input candidates. When “mail transmission” or “mail reception” is specified as the log type related to the input character string, for example, information of the items “name” and “mail address” are displayed as input candidates. Similarly, when another log type is specified as the log type related to the input character string, information of items specified in advance among the information included in the log of the log type is displayed as an input candidate.

  In the above, among the information included in the log related to the input character string (in the example of FIG. 7, the log type is “steps”), the items specified in advance (in the example of FIG. 7, the items “steps” and “ Although the information of “walking distance”) is displayed as an input candidate, the present invention is not limited to this. Information associated with information on items specified in advance may be displayed as input candidates.

  FIG. 8 is a diagram illustrating an example of a screen displayed in the input process when “SHASHIN” is input as the input character string. When the character string “shashin” is inputted, as shown in FIG. 8A, “shashin”, “photograph”, “photo studio”, “shashin”, etc. are extracted from the dictionary DB 112 and converted. Displayed in the candidate area. Further, as the log related to the input character string “shashin”, the log with the log type “photo” shown in FIG. 2F is searched by the related log search unit 104, and the information included in the log is the log type “ It is sent to the input candidate detection unit 105 together with the “photo”. The input candidate detection unit 105 accesses the input candidate setting DB 116, refers to the display setting table 117 corresponding to the log type “photo”, and inputs information on which item of log items whose log type is “photo”. It is determined whether to display as. Here, it is assumed that the item “thumbnail” is set to be displayed as an input candidate in the display setting table. In response to this, the input candidate detection unit 105 and the thumbnail image file name described in the item “thumbnail” and the thumbnail image storage location (for example, a predetermined storage location or the original image recorded in the log) are displayed. Thumbnail image data is acquired based on the same storage location as the storage location and sent to the display control unit 106. The display control unit 106 controls the display unit 12 based on the thumbnail image data received from the input candidate detection unit 105 to display the thumbnail image in the input candidate display area 124. FIG. 8B shows a screen in a state where thumbnail images T1 to T5 are displayed in the input candidate display area 124.

  As shown in FIG. 8C, when the user operates the operation unit 13 to select a thumbnail image T1 (for example, an image designated by the file name photo1_t.jpg in FIG. 2F), the user selects FIG. ), The original image P1 of the thumbnail image T1 (for example, the image specified by the file name photo1.jpg in FIG. 2F) is displayed in the character input area 122. At this time, when the size of the image P1 is larger than the size of the character input area 122, the size of the image P1 may be adjusted to a predetermined size smaller than the size of the character input area 122 and displayed.

  In this way, the input candidate detection unit 105 uses the information of a predesignated item included in the log of the log type related to the input character string (for example, the thumbnail image file name “photo1_t.jpg”). Information associated with the information (for example, thumbnail image T1) may be displayed as an input candidate. Further, the information displayed in the input candidate display area 124 as an input candidate may not be information that is actually input to the character input area 122 (for example, the original image P1 of the thumbnail image T1) when selected. Information related to information inputted at the time of selection (for example, thumbnail image T1) may be used.

  FIG. 9 is a diagram showing an example of a screen displayed in the input process when the character string “Meel” is input as still another example. In the example of the keyword DB 115 shown in FIG. 3, the input character string “Mail” is associated with both the log type “mail transmission” and the log type “mail reception”. Therefore, in step S5 in FIG. 6, both the log type “mail transmission” and the log type “mail reception” are acquired, and in step S6, logs corresponding to each of these two log types are searched. The input candidate detection unit 105 selects items specified in the corresponding display setting table 117 (for example, any log type) from the retrieved log type “mail transmission” log and log type “mail reception” log. Also, the information of the items “name” and “mail address”) is detected and supplied to the display control unit 106. As a result, as shown in FIG. 9, the information (name and email address) acquired from the log with the log type “mail transmission” and the information (name and email) acquired from the log with the log type “mail reception”. Address) is displayed on the display unit 12 as an input candidate. In the example shown in FIG. 9, the display screen distinguishes and displays the information acquired from the log with the log type “mail transmission” and the information acquired from the log with the log type “mail reception”. There are two input candidate display areas 124-1 and 124-2. It should be noted that the input candidate display area 124-1 that displays information acquired from the log with the log type “mail transmission” as an input candidate, and the information acquired from the log with the log type “mail reception” is displayed as an input candidate. Which input candidate display area 124-2 is to be displayed above may be determined based on a display priority of a preset log type. When information including a relatively large number of characters such as an e-mail address is displayed as an input candidate, only a part of the information is displayed in the input candidate display area 124, and when selected by the user, all of the information is displayed in the character input area 122. May be displayed.

  As described above, according to the present embodiment, the information included in the log related to the input character string or the information related to the information is presented to the user as input candidates among the logs indicating the user's action history and the like. The information input operation by the user is simplified.

Here, it is assumed that the user A of the terminal device 1 creates an electronic message such as an electronic mail addressed to the user B of the terminal device 2. In the example described below, the electronic message is an e-mail, but any electronic message may be used, such as a message transmitted / received by SMS (Short Message Service).

  As illustrated in FIG. 13, when the user A of the terminal device 1 inputs a character string (S11), the character string comparison unit 103 of the terminal device 1 acquires a log type related to the input character string (step S12). This log type is acquired as the log type in which the keyword character string included in the input character string or its conversion candidate is associated in the keyword DB 115, as in step S5 of FIG.

  In step S13, the communication partner specifying unit 107 specifies a communication partner. Specifically, the user identification information (user ID) of the user (user B in this example) designated as the e-mail destination is acquired. The user ID may be any information that can identify the user. For example, the user ID may be an e-mail address or a name, but needs to be the same as the information used by the server 3 to manage each user's log. For example, when the user A selects a destination of an e-mail address from the address book 113, the communication partner specifying unit 107 specifies a user as a destination (communication partner) and acquires the user ID based on the selection operation.

  In step S <b> 14, the related log search unit 104 transmits the acquired log type, the user ID of the communication partner (user B), and the user ID of the user (user A) of the terminal device 1 to the server 3. For example, the user ID of the user (user A) of the terminal device 1 is stored in advance in the storage unit 11.

  In step S15, the server 3 that has received the log type, the user ID of the user A, and the user ID of the user B accesses the multi-user log DB 314 and associates it with the log DB of the user A (ie, associated with the user ID of the user A). Log DB) 314-1 and user B's log DB (that is, log DB associated with user B's user ID) 314-2 are searched for a log corresponding to the log type. In addition, all or part of the retrieved logs (for example, a predetermined number of data sets in order from the newest one, or a data set acquired between a predetermined time before the current time and the current time), log type, etc. Is transmitted to the terminal device 1 which is the transmission source terminal device.

  When the server 3 receives logs retrieved from the log DBs 314-1 and 314-2 of the user A and the user B from the server 3, the input candidate detection unit 105 of the terminal device 1 inputs from the information included in the received logs. Information to be displayed as a candidate is detected (step S17). In addition, the display control unit 106 displays the detected information on the display unit 12 so that the user A can select it as an input candidate (step S18). The processes in steps S17 and S18 are the same as the processes in steps S7 and S8 in FIG.

  FIG. 14 is a schematic diagram illustrating an example of a screen displayed in the input process in the first modification. FIG. 14 shows a screen when the character string “Aritai” is input. As shown in FIG. 14, in this example, the display screen is a first input candidate display area 124 that displays log information acquired from the log DB 314-1 of the user (user A) of the terminal device 1 as an input candidate. -1 and a second input candidate display area 124-2 for displaying log information acquired from the log DB 314-2 of the communication partner (user B) as input candidates.

  In this way, in this example, not only the log DB of the user A of the terminal device 1 where characters are entered, but also the log related to the input character string from the log DB of the user B of the terminal device 2 that is the communication partner. The log information of the type is acquired and displayed so as to be selectable by the user A as an input candidate. Therefore, when the user A creates an electronic message addressed to the user B, if the user A wants to input information related to the user B's action history, such as the number of steps of the user B's recent day or the movie that the user B has recently watched. Such information can be input without inquiring B separately.

  Note that the number of communication partners is not limited to one, but may be a plurality. In that case, log information corresponding to the log type related to the input character string may be acquired from the log DBs of each of the plurality of communication partners, and the acquired log information may be displayed as input candidates. In addition, each user may be able to set which user other than himself / herself is allowed to display information included in the log stored in his / her log DB as an input candidate. Such setting information may be transmitted from the terminal device of each user to the server 3 and stored in the storage unit 31 of the server 3 together with the multi-user log DB 314.

3-2. Modification 2
In the first modification, the log DBs of a plurality of users are stored as the multi-user log DB 314 in the storage unit 31 of the server 3, but the present invention is not limited to this. The storage unit 11 of the terminal devices 1 and 2 may store not only the log DB of the user of the own terminal device but also the log DB of another user who can be a communication partner.

  FIG. 15 is a block diagram illustrating a configuration of a terminal device 1A according to the second modification. In this figure, parts common to those in FIG. The terminal device 1A shown in FIG. 15 is different from the terminal device 1 of FIG. 1 in that a multi-user log DB 114A is stored in the storage unit. The multi-user log DB 114A includes other users' log DBs in addition to the user's log DB of the terminal device 1A. Each user's log DB includes one or more types of logs as shown in FIGS. Another user whose log DB is stored in the multi-user log DB 114A of the terminal device 1A may be, for example, a user selected from the users registered in the address book 113 of the terminal device 1A.

  The control unit 10 of the terminal device 1 </ b> A has a predetermined timing (for example, every hour) for a terminal device (not shown) of a user selected among other users registered in the address book 113. Alternatively, a message requesting transmission of log information is transmitted according to a user operation. The terminal device of another user who has received the message transmits log information that has not been transmitted to the terminal device 1A. Upon receiving the log information from the terminal device of another user, the control unit 10 of the terminal device 1A writes it in the multi-user log DB 114A and updates the multi-user log DB 114A.

  With such a configuration, the log information related to the input character string can be obtained not only from the log DB of the user of the terminal device in which characters are input without accessing the server, but also from the log DB of the user as the communication partner. Can be acquired and displayed as input candidates.

3-3. Modification 3
In the above embodiment, it is determined whether the keyword character string included in the keyword DB 115 is included in one input character string and its conversion candidate. If the keyword character string is included, the log type associated with the keyword character string is Identified as a log type related to the input string. However, the present invention is not limited to this. A related log type may be specified using a plurality of input character strings and conversion candidates.

  FIG. 16 is a diagram illustrating a functional configuration of the control unit 10B of the terminal device according to the third modification. In this figure, parts common to those in FIG. The control unit 10B illustrated in FIG. 16 is different from the control unit 10 illustrated in FIG. 5 in that the control unit 10B includes an input character string storage unit 108 that stores a character string input by operating the operation unit 13. The character string storage unit 108 may be realized by, for example, the RAM of the control unit 10 or may be realized by the storage unit 11.

  As an example, after the user inputs the character strings “Yes,” and “Ongakuto”, converts them into converted character strings “Yesterday,” and “Music”, respectively, and confirms the input, then the character string “Eiga” Will be described. FIG. 17 is a schematic diagram illustrating an example of a screen displayed in that case. In FIG. 17, the input character string is displayed in the character string input area 122.

  The input character string storage unit 108 stores not only the currently input character string “Eiga ga” but also the character strings “Kinou” and “Ongakuto” input before that, and the character string comparison unit 103 stores them. Supply. Here, the number of character strings that can be stored in the input character string storage unit 108 is determined by the storage capacity of the input character string storage unit 108 and the length of each character string. The character strings stored in the input character string storage unit 108 are deleted in order from the old character string, and the newly input character string is stored in the empty space.

  The character string comparison unit 103 determines whether any of the keyword character strings stored in the keyword DB 115 is included in each of the plurality of input character strings stored in the input character string storage unit 108, and the input character string A keyword character string included in any of the plurality of input character strings stored in the storage unit 108 is extracted. In the case of this example, the input character string accumulating unit 108 accumulates three character strings of “Kinou,” “Ongakuto”, and “Eigao” and is included in the keyword DB 115 illustrated in FIG. Among the keyword character strings, since the character string “Ongaku” is included in the character string “Ongakuto” and the character string “Eiga” is included in the character string “Eigato”, the character string comparison unit 103 uses the keyword character string “ Extract “Ongaku” and “Eiga”. Then, the log types “music” and “moving image” are specified as the log types associated with the extracted keyword character strings “ongaku” and “eiga”. The identified log type is sent to the related log search unit 104 as in the above embodiment, and the related log search unit 104 accesses the log DB 114 to correspond to each of the log types “music” and “video”. A log is acquired and sent to the input candidate detection unit 105. Here, in the display setting table 117 corresponding to the log type “music”, the item “song name” is specified as an item to be displayed as an input candidate among the log items having the log type “music”, and the log type “movie” is set. In the corresponding display setting table 117, if the item “title” is specified as an item to be displayed as an input candidate among the log items having the log type “moving image”, the input candidate detecting unit 105 sets the log type to “ Information on the “Music” log item “Song Title” (in this example, “Jingle Bell”, “Various People”) and information on the log item “Title” whose log type is “Movie” (this example) Then, “legendary speech”, “rain sound”...) Are acquired and supplied to the display control unit 106. The display control unit 106 displays the received information on the display unit 12 as an input candidate.

  In the image illustrated in FIG. 17, two input candidate display areas 124-1 and 124-2 for displaying each information of a log with a log type “music” and a log with a log type “moving image” as input candidates. Is provided. In addition, here, the input candidate display area 124-1 that displays information acquired from the log having the log type “moving image” related to the newest input character string “Eigaha” as an input candidate is displayed earlier. Arranged above (that is, preferentially) the input candidate display area 124-2 for displaying information acquired from the log having the log type “music” related to the input character string “ongakuto” as input candidates. Has been.

  As described above, by displaying the log type log information related to the plurality of input character strings stored in the character string storage unit 108 as input candidates, the information input operation by the user is simplified. In particular, according to this modification, even for a character string whose input is confirmed, the log information of the related log type is displayed as an input candidate, so that the log related to the character string whose input has already been confirmed. When the user wants to input log information of a type, the user can select and input log information related to the character string without inputting the same character string again.

3-4. Modification 4
In the example shown in the third modification, among the input character strings stored in the character string storage unit 108, a character string that does not include the keyword character string (that is, “Mino”) acquires information that is an input candidate. Was not taken into account. However, information to be displayed as an input candidate may be acquired from information included in the log by using a character string that is considered to indicate the date and time, such as the character string “Kino,”.

  FIG. 18 is a diagram illustrating a functional configuration of the control unit 10 </ b> C of the terminal device according to the fourth modification. In this figure, parts common to those in FIG. The control unit 10C illustrated in FIG. 18 is different from the control unit 10B in FIG. 16 in that the date / time information generation unit 109 is included. The date / time information generation unit 109 includes, for example, “Kinou”, “Sakujitsu”, “Kyoto”, “Honjitsu”, “Ototsu”, “Ototoi” in the character strings stored in the character string storage unit 108. ”,“ Issakujitsu ”,“ 3 Komae ”,“ 1 Shukanmae ”,“ 1 Jikanmae ”, etc., a character string that is considered to be related to the date and time (referred to as a date / time related character string) Is included. These date-related character strings are stored in the storage unit 11 in advance. The user may be allowed to add or delete the date / time related character string stored in the storage unit 11 through the operation unit 13.

  When a date / time related character string is included in the character string stored in the character string storage unit 108, the date / time information generation unit 109 displays the date / time related character string included in the character string stored in the character string storage unit 108. (For example, “Mino”) is extracted, and date / time information is generated by performing a predetermined process on the extracted date / time related character string. For example, when the character string “Kino” is extracted as the date-and-time related character string, the date and time information generation unit performs a date (for example, November 25, 2011) one day before today's date (for example, November 26, 2011). Date / time information indicating (date) is generated, and the generated date / time information is sent to the related log search unit 104. Note that today's date and current time may be acquired by a calendar function and a clock function (not shown) that are normally provided in a normal terminal device, or may be acquired from a server with which the terminal device can communicate. .

  The related log search unit 104 accesses the log DB 114 using the date / time information supplied from the date / time information generation unit 109 in addition to the log type supplied from the character string comparison unit 103, and logs information corresponding to the log type Get the information indicated by the date and time information. For example, when the log types supplied from the character string comparison unit 103 are “video” and “music”, and the date information supplied from the date information generation unit 109 is “November 25, 2011”, the related log search The unit 104 acquires a data set in which the information of the item “date and time” corresponds to “November 25, 2011” among the information included in the log with the log type “video” and the log with the log type “music” Then, the data is supplied to the input candidate detection unit 105. In the example of the log with the log type “video” shown in FIG. 2E, the top data set (data set including “legendary speech” as title information) corresponds to such a data set. . In the example of the log with the log type “music” shown in FIG. 2D, the above two data sets correspond to such a data set.

  FIG. 19 is a schematic diagram illustrating an example of a screen displayed based on the input process according to the fourth modification. In FIG. 19, as in FIG. 17, after the user inputs the character strings “Kino,” and “Ongakuto”, and converts them into converted character strings “Yesterday” and “Music”, respectively, and confirms the input. , The screen when the character string “Eigao” is entered is shown. In the example shown in FIG. 19, the date / time information “November 2011” supplied from the date / time information generation unit 109 is displayed in the input candidate display area 124-1 for displaying the input candidates acquired from the log having the log type “video”. Only the information “legendary speech” of the item “title” included in the data set corresponding to “25th” is displayed, which is different from the example shown in FIG.

  In this way, unnecessary information can be obtained by acquiring information to be displayed as input candidates from information included in the log using a character string that is considered to indicate the date and time stored in the input character string storage unit 108. The possibility of displaying as an input candidate is reduced.

3-5. Modification 5
In the above-described embodiment, on the screen illustrated in FIG. 7, among the log items whose log type is “step count”, information on the items “step count” and “walking distance” specified in the corresponding display setting table 117 is displayed. When displaying as an input candidate, based on the display priority of the predetermined item, the information of the item “number of steps” is displayed before (ie, prioritized) the information of the item “walking distance”. However, when displaying information of a plurality of items as input candidates, the display priority of these items is based on the number of times displayed as input candidates in the past or the number of times selected by the user after being displayed as input candidates. You may decide. Further, in the screen illustrated in FIG. 9, when information included in logs corresponding to two log types “mail transmission” and “mail reception” is displayed as input candidates, a display priority of a preset log type is displayed. Based on the input candidate display area 124-1 for displaying information acquired from a log whose log type is “mail transmission” as input candidates, and information acquired from a log whose log type is “mail reception” as input candidates It is determined which of the input candidate display areas 124-2 to be displayed as (that is, which information is preferentially displayed). However, when displaying information included in logs corresponding to a plurality of log types as input candidates, the display priority may be determined according to the number of times specified as the log type related to the input character string.

  FIG. 20 is a diagram illustrating a functional configuration of the control unit 10D of the terminal device according to Modification 5. In this figure, parts common to those in FIG. The control unit 10D illustrated in FIG. 20 is different from the control unit 10 illustrated in FIG. 5 in that it includes a log type counting unit 201, an item counting unit 202, and a display priority determining unit 203. In this example, the number of times specified as the log type related to the input character string is stored for each log type, and the number of times displayed as the input candidate and the user selected after being displayed as the input candidate are selected. The display / selection number DB 119 for storing the number of times stored is stored in the storage unit 11.

  FIG. 21 is a schematic diagram illustrating an example of the specific number of times DB 118. As shown in the figure, in the specific number of times DB 118, for each log type, the number of times specified as the log type related to the input character string (that is, the keyword character string associated with the log type is the input character string or its The number of times included in the conversion candidate) is stored. When the log type counting unit 201 acquires the log type related to the input character string from the character string comparing unit 103, the log type counting unit 201 increments the specific number of acquired log types by one in the specific number DB 118.

  FIG. 22 is a schematic diagram illustrating an example of the display / selection number DB 119. FIG. 22 shows a display / selection number DB 119 for the log type “step count” as an example. As shown in the figure, in the display / selection count DB 119, for each item of the log type “step count”, the number of times displayed as an input candidate (display count) and the input candidate displayed after being displayed as the input candidate are displayed. The number of times (number of selections) is stored. When the display control unit 106 causes the display unit 12 to display the information acquired from the log of the log type related to the input character string as an input candidate, the item counting unit 202 displays the log type and the item from the display control unit 106. In the display / selection count DB 119, the display count of the received log type item is incremented by one. Further, when the user operates the operation unit 13 and the display control unit 106 displays the selected input candidate in the character string input area 122 of the screen in response to selecting any of the displayed input candidates, The item counting unit 202 receives information indicating the item of the selected input candidate from the display control unit 106, and increments the value of the number of selections of the item by 1 in the display / selection number DB 119.

  The display priority determination unit 203 determines the display priority of each log type based on the specific number of each log type stored in the specific number DB 118. For example, a higher priority is set for a log type with a higher specific number of times. The display priority determination unit 203 determines the display priority of each item based on the display count and selection count of each item stored in the display / selection count DB 119. For example, the display priority of an item is increased as the number of times of display increases and as the number of selections increases.

  When the display control unit 106 displays the information acquired from the log of the log type related to the input character string on the screen of the display unit 12 as an input candidate, based on the priority determined by the display priority determination unit 203. Display. Thereby, possibility that information with high user's interest will be preferentially displayed as an input candidate increases.

3-6. Modification 6
In the above embodiment, the user uses one terminal device, but the present invention is not limited to this. One user may use a plurality of terminal devices, and each terminal device may collect logs.

  FIG. 23 is a diagram illustrating an example of a configuration of a communication system 100A according to the sixth modification. This system 100A includes N (N is an integer of 2 or more) terminal devices (for example, mobile phones, tablet terminals, notebook computers, desktop computers, etc.) 1-1 to 1 used by one user A. -N, and these terminal apparatuses 1-1 to 1-N can communicate with each other via the network 4. The hardware configuration of each of the terminal devices 1-1 to 1-N may be the same as the configuration illustrated in FIG. 1, but the multiple terminal log DB 114B including logs collected by the multiple terminal devices in the storage unit 11 Is different.

  FIG. 24 is a schematic diagram illustrating a configuration of the multi-terminal log DB 114B stored in the storage unit 11 of each of the terminal devices 1-1 to 1-N in the system 100A illustrated in FIG. The multiple terminal log DB 114B includes first to Nth log DBs 114b1 to 114bN corresponding to N terminal apparatuses 1-1 to 1-N. In the first to Nth log DBs 114b1 to 114bN, various kinds of logs collected by the corresponding terminal devices 1-1 to 1-N identify terminal identification information (terminal IDs) for identifying the respective terminal devices 1-1 to 1-N. ) Is stored in association with Each of the N terminal devices 1-1 to 1-N is connected to another terminal device used by the same user via the network 4 according to a predetermined timing (for example, every hour) or a user operation. On the other hand, the terminal device that requests log transmission returns the untransmitted log data together with its own terminal ID to the terminal device that transmitted the request. For example, when the terminal device 1-1 transmits a log transmission request to the other terminal devices 1-2 to 1-N, each of the other terminal devices 1-2 to 1-N has not yet sent to the terminal device 1-1. Log data that has not been transmitted is transmitted to the terminal device 1-1. The transmission request transmitted from the terminal device 1-1 includes information indicating the transmission date and time of the previous log data, and the other terminal devices 1-2 to 1-N that have received the transmission request are indicated by the information. Log data after the transmission date and time may be transmitted to the terminal device 1-1. The terminal device 1-1 of the request transmission source that has received the log data from the other terminal devices 1-2 to 1-N stores the received log data in the log DBs 114b2 to 114bN of the corresponding terminal devices 1-2 to 1-N. Remember.

  When the user performs character input in any of the plurality of terminal devices 1-1 to 1-N, the control unit 10 of the terminal device specifies a log type related to the input character string and corresponds to the specified log type Log information is acquired from each of the log DBs 114b1 to 114bN corresponding to the N terminal devices 1-1 to 1-N included in the multiple terminal log DB 114B, and the acquired information is displayed as input candidates. For example, if a user collects daily steps as a log using a mobile device, the user collected a blog or email about recent walking activities using a desktop computer at home. Information such as the number of steps and average walking speed is acquired as input candidates from the step count log (illustrated in FIG. 2B) and displayed. As described above, according to the present modification, when one user uses a plurality of terminal devices, the characters are collected by the terminal device in which the input operation is performed when performing character input on any of these terminal devices. Information related to the input character string is acquired not only from the log but also from a log collected by another terminal device used by the user and displayed as an input candidate. Therefore, the information input operation by the user is further simplified as compared with the case where the input candidates are acquired and displayed only from the logs collected by the terminal device itself on which the character input operation is performed.

  Each of the N terminal devices 1-1 to 1-N used by one user has a plurality of terminal log DBs 114B including the first to Nth log DBs 114b1 to 114bN corresponding to these N terminal devices. Instead of or in addition, for example, a server connected to the network 4 may store a plurality of terminal log DBs including a plurality of log DBs corresponding to a plurality of terminal devices in association with the user ID. In that case, when a character is input in each terminal device, the control unit of each terminal device accesses a plurality of terminal log DBs stored in the server via the network 4 and logs information related to the input character string. You may acquire from the information of the log contained in multiple terminal log DB. Moreover, the log DB of each user included in the multi-user log DB illustrated in FIGS. 11 and 15 may be a multi-terminal log DB including logs collected by a plurality of terminal devices used by the user.

3-7. Modification 7
In the above embodiment, when the information acquired from the log of the log type related to the input character string is displayed as an input candidate, the information included in the newest data set is displayed at the top, and the older information is displayed below. However, the present invention is not limited to this. When the information displayed as the input candidate is numerical data such as the number of steps, for example, a deviation from the average value of the numerical data in a predetermined period (for example, the past month or the past year) is predetermined. Only numerical data larger than the value may be extracted and displayed as input candidates. In addition, numerical data displayed as input candidates may be displayed as input candidates with a priority according to the magnitude of deviation from the average value. For example, if a user who normally walks about 5000 steps a day walks more than 10,000 steps a day, the number of steps that differ greatly from the normal number of steps, such as mail or blog that the user creates It is based on the assumption that numerical data that is very different from ordinary numerical values is highly likely to be input by the user. For example, in the input candidate detection unit 105 shown in FIG. 5, the calculation of the average value of the numerical data in the predetermined period as described above, and the numerical data whose deviation from the average value is larger than the predetermined value Extraction may be performed and the extracted numerical data may be supplied to the display control unit 106. In this case, the input candidate detection unit 105 functions as a variation log extraction unit that extracts information of a log with a large variation. Further, the display control unit 106 may display the numerical data received from the input candidate detection unit 105 as input candidates in order from the top in accordance with the deviation from the average value.

  As described above, when the information displayed as the input candidate is numerical data, only the numerical data whose deviation from the average value of the numerical data in a predetermined period is larger than the predetermined value is extracted as the input candidate. Information that is likely to be input by the user by displaying numerical data that is displayed and / or displayed as input candidates as input candidates with a priority according to the degree of deviation from the average value Can be displayed so that the user can easily select them.

3-8. Modification 8
In the above embodiment, the conversion candidate or input candidate specified by the user operating the movement key can be changed, and when the user presses the confirmation key, the conversion candidate or input candidate specified at that time is selected. However, the present invention is not limited to this. For example, when the operation unit 13 has a touch pad, a conversion candidate or an input candidate displayed at a position touched by the user may be selected and displayed in the character input area 122. Also in this case, similarly to the above embodiment, even if a conversion candidate or input candidate is selected and displayed in the character input area 122, the display of the conversion candidate display area 123 and the input candidate display area 124 may be maintained as it is. That is, when a plurality of conversion candidates and / or input candidates are displayed, the display control unit 106 allows the selection of two or more input candidates in succession.

  As another method, when the user touches the touch pad, the conversion candidate or input candidate displayed at the touched position is specified, and the user presses the enter key in that state (or presses the corresponding soft button). Touched), the designated conversion candidate or input candidate may be selected and displayed in the character input area 122. In this case, a plurality of conversion candidates or input candidates may be simultaneously specified by touch. Thereby, since the user can select a plurality of conversion candidates or input candidates and display them in the character input area 122, the operation of character input is simplified.

3-9. Modification 9
In the above embodiment, the related log search unit 104 acquires the log of the log type supplied from the character string comparison unit 103 from the log DB 114 and sends the log to the input candidate detection unit 105. The input candidate detection unit 105 The information of the item specified by the corresponding display setting table 117 or the information related to the information is acquired from the information included in the log received from the unit 104 and supplied to the display control unit 106 for display as an input candidate. However, the present invention is not limited to this. Based on the log type received from the character string comparison unit 103, the related log search unit 104 extracts items to be displayed as input candidates by referring to the corresponding display setting table 117 of the input candidate setting DB 116, and corresponds to the log type. Only information of items to be displayed as input candidates among information included in the log to be acquired may be acquired from the log DB 114 and supplied to the display control unit 106. That is, the related log search unit 104 may also function as the input candidate detection unit 105.

3-10. Other Modifications In the above embodiment, the character string that can be input is a hiragana character string, but the present invention is not limited to this. For example, a character string may be input by so-called Roman character input.
