Description

  The present invention relates to an information processing terminal and dictionary data synchronization method for synchronizing predictive conversion dictionary data used for predictive conversion.

  Conventionally, methods for synchronizing data among a plurality of information processing devices have been studied. For example, when there is a portable information device having the same user identification number in a range where wireless communication is possible, data received from another portable information device, such as schedule data, alarm data, address book data, memo pad data, etc. Has been disclosed (see Patent Document 1 below). In this data synchronization method, when the update information stored in the storage unit is older than the update information of another portable information device, the data is updated with the data received from the other portable information device.

  However, when predictive conversion dictionary data generated based on a character input history from a user is targeted as data synchronization, the above-described conventional data synchronization method does not always provide data that is highly convenient for the user. It tends to be impossible. That is, in the above data synchronization method, the data is updated to new update information, and therefore, the data may not necessarily be updated to the predictive conversion dictionary data that well reflects the user's character input history.

  Therefore, the present invention has been made in view of such problems, and information processing that can improve user convenience by updating data to predictive conversion dictionary data in which a user's character input history is reflected. An object is to provide a terminal and a dictionary data synchronization method.

In order to solve the above problems, an information processing terminal according to the present invention includes a dictionary data storage unit that stores predictive conversion dictionary data to be output for a character string input from a user, and a character conversion process using the predictive conversion dictionary data. Based on the character string determined by the user by executing the character conversion control means for updating the predictive conversion dictionary data, and the execution of the character conversion process is detected, and the number of times of the terminal that is detected is The number-of-times information holding means for holding, the number-of-information receiving means for receiving the number of times of other terminal that is the number of times of character conversion processing executed in the terminal device from the terminal device in the area capable of wireless communication, the number of times of own terminal and the number of other terminals When the comparison means to compare and the number of times of own terminal is larger than the number of other terminals, the predicted conversion dictionary data is transmitted to the terminal device, and when the number of own terminals is smaller than the number of other terminals, And a dictionary data communication means for reflecting the predictive conversion dictionary data receiving and stored in the dictionary data storage unit a predictive conversion dictionary data from the device.

Alternatively, the dictionary data synchronization method of the present invention includes a dictionary data storage step in which the dictionary data storage means stores predictive conversion dictionary data to be output for a character string input from a user, and the character conversion control means has a predictive conversion. The character conversion control step for updating the predictive conversion dictionary data based on the character string determined by the user by executing the character conversion processing using the dictionary data and the number information holding means detect the execution of the character conversion processing. In addition, the number information holding step for holding the number of times of the own terminal that is the number of executions detected, and the number information receiving means are the number of times character conversion processing is executed from the terminal device in the area capable of wireless communication to the terminal device. The number of times information receiving step for receiving the number of times of the terminal, the comparison means, the comparison step of comparing the number of times of the own terminal and the number of other terminals, and the dictionary data communication means, If the terminal count is greater than the other terminal count, the predicted conversion dictionary data is transmitted to the terminal device. If the own terminal count is less than the other terminal count, the predicted conversion dictionary data is received from the terminal device and the dictionary is received. A dictionary data communication step for reflecting the prediction conversion dictionary data stored in the data storage means.

  According to such an information processing terminal or dictionary data synchronization method, the number of character conversion processes using the predictive conversion dictionary data is detected as the number of times of the own terminal, and the character in the terminal device from the terminal device in the area where wireless communication is possible When the number of times of conversion processing is received as the number of other terminals and the number of own terminals is greater than the number of other terminals, the predicted conversion dictionary data is transmitted to the terminal device, and the number of times of own terminal is less than the number of other terminals The prediction conversion dictionary data received from the terminal device is reflected in the prediction conversion dictionary data. As a result, the prediction conversion dictionary data of the other terminal whose prediction conversion dictionary data held in the terminal in which the character conversion processing using the prediction conversion dictionary data is frequently used is close to the range where wireless communication with the terminal is possible Since it is reflected in the data, it is possible to hold the predictive conversion dictionary data that best reflects the user's character input history in a plurality of terminals. As a result, the convenience of the user of the terminal that performs character conversion input can be improved.

  It is preferable that a terminal detection unit for detecting a terminal device capable of wireless communication is further provided, and the number-of-times information receiving unit requests transmission of the number of other terminals to the terminal device detected by the terminal detection unit. By so doing, it is possible to efficiently synchronize the predictive conversion dictionary data with a terminal that has approached the range where wireless communication is possible.

  It is also preferable that the apparatus further includes a position change detection unit that detects a change in position, and the terminal detection unit detects the terminal device at a timing when the position change is reduced by the position change detection unit. If such a configuration is adopted, detection of another terminal device is started from a terminal that is likely to be carried, and therefore data synchronization processing is started by a terminal that is likely to be used by a user, and a plurality of terminals are Can reduce unnecessary power consumption.

  Furthermore, it further comprises terminal device group information holding means for holding terminal device group information for specifying the terminal device group that shares the predictive conversion dictionary data, and the terminal detection means refers to the terminal device group information, and It is also preferable to detect the included terminal device.

In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a schematic configuration diagram of a mobile phone terminal 1 according to a preferred embodiment of the present invention. A cellular phone terminal 1 shown in FIG. 1 is an information processing terminal that can be connected to a mobile communication network adopting a mobile communication system such as IMT-2000 (International Mobile Telecommunication 2000). Note that various terminal devices such as a PDA (Personal Digital Assistants), a personal computer, and a smartphone can be employed as the information processing terminal according to the present embodiment.

  This mobile phone terminal 1 is an information communication terminal used by a user who wants to create a text when creating text data, when creating an e-mail, or when inputting a search keyword to the WEB site. , A display unit 21 for displaying data such as a display, an image, and the like, an input unit 22 for receiving input of a character string from a user such as an input button and a touch panel, a character conversion control unit 23, and a conversion count holding unit (number of times Information holding means) 24, position change detection section (position change detection means) 25, terminal detection section (terminal detection means) 26, number information transmission / reception section (number information reception section) 27, and comparison section (comparison means). 28, dictionary data communication unit (dictionary data communication unit) 29, dictionary data storage unit (dictionary data storage unit) 30, character conversion history information storage unit 31, and terminal device group information storage And a (terminal device group information holding means) 32. Hereinafter, functions of each component of the mobile phone terminal 1 will be described in detail.

  The input unit 22 of the mobile phone terminal 1 accepts input of character string data using a data input device (not shown) such as an input key or a touch panel from a user, and delivers the character string data to the character conversion control unit 23 Have Further, the input unit 22 has a function of accepting a confirmation input from the user for confirming an input character from among a plurality of prediction conversion candidates displayed on the display unit 21 when the user creates a sentence.

  The character conversion control unit 23 displays a plurality of predictive conversion candidates for the character string data by referring to the dictionary data storage unit 30 according to the character string data input by the user at the time of text creation by the user. To control. That is, the dictionary data storage unit 30 stores prediction conversion candidates corresponding to the input character string data in advance as prediction conversion dictionary data, and the character conversion control unit 23 selects the input character string from the prediction conversion dictionary data. Predictive conversion candidates corresponding to the data are extracted and displayed.

  Further, the character conversion control unit 23 receives a selection input from the user for the displayed prediction conversion candidate via the input unit 22 and performs control so that the prediction conversion candidate is determined as an input character according to the received selection input. . The confirmed predictive conversion candidate is delivered as text data to various application programs such as an e-mail program, a text creation program, and a browser. Further, each time an input character is determined at the time of writing a sentence, the character conversion control unit 23 reads predicted conversion dictionary data stored in the dictionary data storage unit 30 based on the input character, characters input before and after the input character, and the like. In addition to updating, character conversion history information relating to the confirmed input character is generated and stored in the character conversion history information storage unit 31.

  FIG. 2 shows an example of character conversion history information generated by the character conversion control unit 23. As shown in the figure, the input character “o” received from the user, the confirmed character string “oyo” confirmed as the input character from the prediction conversion candidates for the input character, and the date and time “ 2011/2/9 10:01:20 "are stored in association with each other. This character conversion history information is accumulated and stored every time an input character is determined by the user.

  The conversion count holding unit 24 detects the execution of the character conversion process using the predictive conversion dictionary data at a predetermined timing, and holds the number of times of the terminal itself regarding the execution count. Specifically, the conversion count holding unit 24 refers to the character conversion history information storage unit 31, counts the number of records of character conversion history information related to the date and time within a predetermined period, and holds the count as the number of times of the terminal itself. . For example, the conversion count holding unit 24 counts character conversion history information including the date and time within the latest 48 hours. Here, as the timing for detecting the number of times of own terminal, the timing at a certain period, the timing at which the input character is confirmed by the user, or the position change detecting unit 25 described below detects that the position change has decreased. Timing.

  The position change detection unit 25 detects a change in the position of the mobile phone terminal 1. That is, the position change detection unit 25 includes an acceleration sensor, detects the acceleration of the mobile phone terminal 1, and notifies the terminal detection unit 26 of the detected acceleration. Note that the position change detection unit 25 may detect a position change by a positioning function or the like that specifies a base station area that is currently located using a GPS positioning function or mobile communication.

  Based on the acceleration notified from the position change detection unit 25, the terminal detection unit 26, after the change of the position of the mobile phone terminal 1 occurs, the timing at which the change of the position decreases, that is, the acceleration once increases. The terminal device capable of wireless communication is detected at a decreased timing. For example, the terminal detection unit 26 uses a wireless communication such as wireless LAN communication, Bluetooth communication, infrared communication, or the like to transmit a request signal for requesting synchronization processing of predictive conversion dictionary data toward the periphery, and the request signal By receiving a response signal including a terminal ID that identifies the terminal device that has received the message from surrounding terminal devices, a terminal device capable of wireless communication is detected. Here, the terminal detection unit 26 refers to the terminal device group information stored in the terminal device group information storage unit 32 to detect only the terminal devices included in the terminal group specified by the terminal device group information. . As shown in FIG. 3, the terminal device group information storage unit 32 stores terminal device group information registered in advance by the user via the input unit 22, and the terminal device group information includes prediction conversion. A combination of a plurality of terminal IDs that specify a group of terminal devices that are targets of dictionary data synchronization processing is stored. And the terminal detection part 26 detects the terminal device specified by the terminal ID as a terminal device in which radio | wireless communication is possible, when the response signal containing terminal ID contained in terminal device group information is received. Note that the terminal detection unit 26 may perform pairing setting by password authentication or the like in advance with a plurality of terminal devices, and detect only the terminal devices that have been paired.

  When the terminal detection unit 26 detects two or more terminal devices in an area where wireless communication is possible, the number information transmission / reception unit 27 receives prediction conversion dictionary data from the terminal device. The number of other terminals related to the number of executions of the character conversion process using is received using wireless communication. That is, the frequency information transmission / reception unit 27 receives the terminal ID related to the terminal device detected from the terminal detection unit 26, and transmits a request signal for requesting the transmission of the number of other terminals to the terminal device specified by the terminal ID. In response to this, the number of other terminals transmitted from the terminal device is received. In addition, when there is one terminal device in the wireless communicable area detected by the terminal detection unit 26, the number of own terminals held by the conversion number holding unit 24 for the terminal device is Send using wireless communication.

  The comparison unit 28 compares the own terminal count held by the conversion count holding unit 24 with the other terminal count received from the terminal device detected by the terminal detection unit 26. As a result, when the number of times of the own terminal is larger than the number of other terminals, the comparison unit 28 selects the “master terminal” that is the reflection source of the predictive conversion dictionary data, and a plurality of terminal devices that have received the number of other terminals. This is set as a “slave terminal” to which the prediction conversion dictionary data is reflected, and the setting contents are transferred to the dictionary data communication unit 29. On the other hand, if the number of times of own terminal is less than the number of other terminals, the own terminal is “slave terminal”, and the terminal device having the largest number of other terminals among the plurality of terminal devices that have received the number of other terminals is “master terminal” "And set contents are transferred to the dictionary data communication unit 29.

  When the own terminal is set as the master terminal, the dictionary data communication unit 29 transmits the predicted conversion dictionary data stored in the dictionary data storage unit 30 to all the slave terminals by wireless communication, and the predicted conversion Reflect dictionary data. Further, when the own terminal is set as a slave terminal, the prediction conversion dictionary data is requested from the master terminal, the prediction conversion dictionary data transmitted from the master terminal is received accordingly, and the received prediction conversion is received. The dictionary data is reflected in the predictive conversion dictionary data stored in the dictionary data storage unit 30. Specifically, the received predictive conversion dictionary data is overwritten on the predictive conversion dictionary data stored in the dictionary data storage unit 30.

  Hereinafter, the operation of the mobile phone terminal 1 will be described with reference to FIGS. 4 to 7, and the dictionary data synchronization method in the mobile phone terminal 1 will be described in detail. As shown in FIG. 4, it is assumed that both or one of the terminal devices 1A and 1B is located in an area where the mobile phone terminal 1 can perform wireless communication when the mobile phone terminal 1 moves. The operation of the terminal 1 will be described. Here, it is assumed that the terminal devices 1A and 1B have the same functional configuration as the mobile phone terminal 1. FIG. 5 is a flowchart showing the operation at the time of the character conversion process by the mobile phone terminal 1, and FIGS. 6 and 7 are flowcharts showing the operation at the time of the prediction conversion dictionary synchronization process by the mobile phone terminal 1.

  First, with reference to FIG. 5, the operation | movement at the time of the character conversion process of the mobile telephone terminal 1 is demonstrated. First, a start instruction for character conversion processing using an application program such as an e-mail program is received from the user of the mobile phone terminal 1 (step S101). Then, after the text data input screen is displayed on the display unit 21 by the character conversion control unit 23, a predicted conversion candidate for the input character string input by the user is extracted from the dictionary data storage unit 30 and displayed. An input character confirmation operation is accepted from the user (step S102). In response to this, the character conversion control unit 23 stores the combination of the input character string and the confirmed character string in the character conversion history information storage unit 31 as character conversion history information (step S103). Further, the conversion count holding unit 24 refers to the character conversion history information storage unit 31 at a predetermined timing, counts the number of records of the character conversion history information related to the date and time within the latest predetermined period, and the count number is the own terminal count. (Step S104).

  Next, with reference to FIG. 6, the operation | movement at the time of the synchronous process of the prediction conversion dictionary data of the mobile telephone terminal 1 is demonstrated. First, the movement of the mobile phone terminal 1 is detected by the position change detection unit 25 (step S201). In response to the detection result, the terminal detection unit 26 determines whether or not the movement stop has been detected after the movement of the mobile phone terminal 1 has occurred (step S202).

  As a result of the determination, when the movement stop is not detected (step S202; NO), the determination is repeated. On the other hand, if a stop of movement is detected as a result of the above determination (step S202; YES), wireless communication is possible by the terminal detection unit 26 transmitting a synchronization processing request to the surroundings using wireless communication. The terminal devices 1A and 1B are detected (step S203).

  Then, the terminal detection unit 26 determines whether there is a response signal received from the terminal devices 1A and 1B capable of wireless communication (step S204). As a result, when it is determined that there is no response signal (step S204; NO), the data synchronization process is terminated. On the other hand, if it is determined that there is a response signal (step S204; YES), it is further determined by the frequency information transmission / reception unit 27 whether or not there are two or more terminal devices that have received the response signal ( Step S205).

  As a result of the determination, when it is determined that there are two or more terminal devices that have received the response signal, for example, when both are the terminal devices 1A and 1B (step S205; YES), the number information transmission / reception unit 27, a request signal for requesting the terminal devices 1A and 1B to transmit the number of other terminals is transmitted, and the number of other terminals transmitted from the terminal devices 1A and 1B is received (step S206). Thereafter, the comparison unit 28 compares the own terminal count held by the conversion count holding unit 24 with the other terminal counts received from the terminal devices 1A and 1B detected by the terminal detection unit 26 (step S207). .

  As a result, when the number of times of the own terminal is larger than the number of other terminals (step S207; YES), the predictive conversion dictionary data stored in the dictionary data storage unit 30 is converted by the terminal detection unit 26 by the dictionary data communication unit 29. It is transmitted to the detected terminal devices 1A and 1B (step S208). On the other hand, when the own terminal count is smaller than the other terminal count (step S207; NO), the dictionary data communication unit 29 obtains predicted conversion dictionary data from the terminal device having the largest number of other terminals among the terminal devices 1A and 1B. The received predictive conversion dictionary data is overwritten on the predictive conversion dictionary data stored in the dictionary data storage unit 30 (step S209).

  Moving to FIG. 7, if it is determined that there are less than two terminal devices that have received the response signal as a result of the determination in step S205, for example, if there is only one terminal device 1A (step S205). NO), the number-of-times information transmission / reception unit 27 transmits the number of times of the own terminal held by the conversion number holding unit 24 to the terminal device 1A as the number of other terminals for the terminal device 1A (step S210). . Thereafter, the terminal device 1A compares the own terminal count held in the terminal device 1A with the other terminal count transmitted by the count information transmitting / receiving unit 27 (step S211).

  As a result, when it is determined that the terminal device 1A has more times than the other terminals (step S211; YES), after the mobile phone terminal 1 receives the predictive conversion dictionary data from the terminal device 1A, The prediction conversion dictionary data stored in the dictionary data storage unit 30 is overwritten (step S212). On the other hand, when the terminal device 1A has the number of times of its own terminal less than the number of other terminals (step S211; NO), the terminal device 1A receives the predictive conversion dictionary data from the mobile phone terminal 1 and then receives the predictive conversion received. The dictionary data is overwritten on the predictive conversion dictionary data stored in the terminal device 1A (step S213).

  According to the mobile phone terminal 1 described above, the number of character conversion processes using the predictive conversion dictionary data is detected as the number of times of the own terminal, and the terminal devices 1A and 1B in the area where wireless communication is possible can be performed by the terminal devices 1A and 1B. Is received as the number of times of other terminals, and when the number of times of own terminal is greater than the number of times of other terminals, the predicted conversion dictionary data is transmitted to the terminal devices 1A and 1B, and the number of times of own terminals is the number of times of other terminals. If the number is less than that, the prediction conversion dictionary data received from the terminal device having a large number of other terminals among the terminal devices 1A and 1B is reflected in the prediction conversion dictionary data. As a result, the prediction conversion dictionary data of the other terminal whose prediction conversion dictionary data held in the terminal in which the character conversion processing using the prediction conversion dictionary data is frequently used is close to the range where wireless communication with the terminal is possible Since it is reflected in the data, it is possible to hold predictive conversion dictionary data in which the user's character input history is best reflected in the plurality of terminal devices 1, 1A, 1B. As a result, prediction conversion candidates optimized for the user can be displayed on a plurality of terminals, smooth character input can be realized, and the convenience of the user of the terminal that performs character conversion input can be improved.

  Since the mobile phone terminal 1 requests the terminal devices 1A and 1B detected by the terminal detection unit 26 to transmit the number of other terminals, the prediction conversion dictionary can be efficiently used with a terminal that is close to a wireless communicable range. Data synchronization can be performed.

  In addition, when the terminal detection unit 26 detects the terminal devices 1A and 1B at the timing when the movement is stopped by the position change detection unit 25, detection of another terminal device is started from a terminal that is likely to be carried. Therefore, data synchronization processing is started by a terminal that is highly likely to be used by the user. As a result, there is only a terminal with little movement and a low possibility of being used by the user, and it is possible to prevent the data synchronization processing from being executed until there is no need for data synchronization. Can be suppressed. Moreover, a terminal device can also be efficiently detected by detecting a surrounding terminal device after moving.

  Furthermore, since the terminal detection unit 26 detects only the terminal devices included in the terminal device group with reference to the terminal device group information, a plurality of terminals that perform data synchronization with each other in advance are registered, By executing the data synchronization, the data synchronization process can be efficiently executed and the convenience of the user can be further improved.
