Description

  The present invention relates to a data input device, a data input method, and a program for inputting data to an electronic document such as an electronic mail.

  Many portable terminal devices such as mobile phones, PHS (Personal Handyphone System), PDA (Personal Data Assistance, Personal Digital Assistants) can send and receive e-mails.

  However, many portable terminal devices are miniaturized so as to be portable, and the operation unit is small.

  For this reason, inputting data into an e-mail with a mobile terminal device is often accompanied by considerable difficulty as compared to inputting data with a keyboard used in a normal desktop computer.

  FIG. 2 is a diagram for explaining the input candidate character string storage area 21 of the work memory 15 of the mobile phone 11 shown in FIG.

  As shown in FIG. 2, the input candidate character string storage area 21 has a destination mail address (transmission destination mail address) storage area 22.

  In the present embodiment, the input candidate character string storage area 21 has n destination mail address storage areas 22 respectively corresponding to n (n is a natural number of 1 or more) destination mail addresses. Hereinafter, the destination email address is also referred to as a destination email address.

  The destination mail address storage area 22 includes a destination mail address storage memory 23, a title character string storage memory 24, and a text string storage memory 25.

  The destination address storage memory 23 stores the destination mail address of the e-mail.

  The character string storage memory 24 for the title is a character string input to the title of the e-mail corresponding to the destination e-mail address stored in the destination e-mail address storage memory 23 and the e-mail transmitted (or created). Frequency information representing the time zone and the input frequency of the character string that is input to the title of the e-mail sent (or created) in that time zone is stored. Note that m (m is a natural number of 1 or more) records can be stored for sets of character strings, time zones, and frequency information.

  The text string storage memory 25 is a text string input in the text of the email corresponding to the destination email address stored in the destination email address storage memory 23, and the time when the email was sent (or created). The band and the frequency information indicating the input frequency input in the body of the e-mail in which the character string is transmitted (or created) in the time period are stored. Note that a set of character strings, time zones, and frequency information can be stored for p (p is a natural number of 1 or more) records.

  In the present embodiment, the above time zone is divided into two sections, daytime and nighttime.

  FIG. 3 is a flowchart for explaining input candidate character string storage processing and update processing in the input candidate character string storage region 21 in the mobile phone 11 shown in FIG.

  As shown in FIG. 3, the CPU 12 checks the destination email address of the email sent by the user in step S31, and the destination email address already exists in the input candidate character string storage area 21 in step S32. It is determined whether or not to do.

  If the destination mail address of the e-mail already exists in the input candidate character string storage area 21 in step S32, the CPU 12 determines in step S33 the time zone when the e-mail was transmitted (or created) and the e-mail. Check whether the same character string already exists in the destination e-mail address storage area 22 corresponding to the e-mail destination e-mail address. Determine whether or not.

A state is shown in which choices of automatic input candidate sentences are displayed on the e-mail creation screen 40.

  As described above, in the present embodiment, in the process of creating an e-mail, the user inputs data into the destination input area and then inputs the data into the title input area and the text input area. Data with high input frequency corresponding to the input data is displayed as input candidates.

  Therefore, the user simply selects the data to be input to the title input area and the text input area from the input candidates having a high input frequency corresponding to the data input to the destination input area, and immediately inputs the title input area and the text input. Since data can be input to the area, it is possible to reduce the burden on the user by making it easier to input data to the e-mail.

  In this embodiment, the user can edit input candidate character strings in the title input area and the text input area.

  Hereinafter, a specific example of the operation of the mobile phone 11 when editing the input candidate character string will be described.

  FIG. 5 is a diagram for explaining a specific example of the operation of editing the input candidate character string stored in the input candidate character string storage area 21 of the mobile phone 11 shown in FIG.

  FIG. 5D shows that when the title or text in FIG. 5B or FIG. 5C is focused and the edit 52 button is selected by the user's operation, the display control unit 18 The character editing screen is displayed. On the character editing screen, a character string can be edited by a user operation. When the confirm 55 button is selected by the user's operation, the CPU 12 confirms the edited character string, updates the character string stored in the input candidate character string storage area 21, and stores it. .

As described above, in this embodiment, since the user can edit the input candidate character strings in the title input area and the text input area, the input candidate character string is changed to a character string expected by the user. The effect that it is possible is acquired.
(2) Second Embodiment (2-1) Outline of the Present Embodiment This embodiment is applied to a data input device for inputting data to the first and second input areas provided in an electronic document. Is.

  As shown in FIG. 6, in the data input device of this embodiment, for each first data input to the first input area, the second input area of the electronic document corresponding to the first data is displayed. The storage unit 100 that stores the input second data together with the input frequency, and when the first data is input to the first input area, it is stored in the storage unit 100 corresponding to the first data. And a control unit 200 that displays the second data as input candidates according to the input frequency.

  As a result, the user simply selects the second data from the input candidates having a high input frequency corresponding to the first data input to the first input area, and then immediately selects the second data to the second area. Therefore, it is possible to reduce the burden on the user by making the data input operation to the electronic document easier.

  Furthermore, in the data input device of the present embodiment, the storage unit 100 stores the second data together with the input frequency for each additional information such as an input time period (transmission time period), and the control unit 200 stores the second data. Are displayed as input candidates according to the input frequency for each additional information.

As described above, the present embodiment is applicable not only to the electronic mail described in the first embodiment but also to an electronic document (for example, a schedule table) having a plurality of input areas. The outline of the present embodiment will be described using mail as an example.
(2-2) Example when this embodiment is applied to an electronic mail The electronic mail includes the following three input areas.

(A) Address (email address)
(B) Title (title, subject)
(C) Text In this embodiment, data is input to another input area (second input area) based on data (first data) in any input area (first input area) of an e-mail. Data (second data) input candidates are displayed.

  That is, in the present embodiment, as described in the first embodiment, the input candidates for the title and the text (second input area) are displayed with reference to the destination (first input area) as described in the first embodiment. The input candidates of the destination and the text (second input area) may be displayed based on the title (first input area), or the text (first input area) may be used as a reference. You may display the input candidate of a destination and a title (2nd input area).

  That is, according to the present embodiment, for each data (first data) in any input area (first input area) of the e-mail, another area (second) of the e-mail corresponding to the first data is stored. Data (second data) is stored together with the input frequency, and when the first data is input to the first input area at the time of creation of the e-mail, the first data is stored. The second data stored corresponding to the data is displayed as an input candidate according to the input frequency.

  In addition, the following additional information is added to the electronic mail at the time of transmission.

(A) Transmission date (b) Transmission time (c) Source Therefore, in this embodiment, the second data and its data are added by additional information such as a time zone (transmission time zone) added to the e-mail at the time of transmission. The input frequency may be classified. In this case, the storage unit 100 stores the second data together with the input frequency for each additional information, and the control unit 200 displays the second data as input candidates according to the input frequency for each additional information. In the first embodiment, the time zone is given as an example of the additional information, but the present embodiment is not limited to this. For example, a general mobile phone can hold only one source mail address, but a “2 in 1 (registered trademark)” mobile phone can hold two source mail addresses. Therefore, a transmission source can be used as additional information.

  Further, the body of the e-mail is not only a text sentence but also composed of various data as follows.

(X) Character system (X-1) Text sentence (X-2) Pictograph (Y) Multi data system (Y-2) Image (Y-3) Voice (Y-4) Decoration (decoration)
Therefore, in the present embodiment, for the text, the second data and its input frequency may be classified according to the type of the second data. In this case, the storage unit 100 stores the second data together with the input frequency for each type of the second data, and the control unit 200 stores the second data for each type of the second data. Display as input candidates according to frequency. In this case, the present embodiment is applied to perform the following operation.

Pictogram: Displays pictogram input candidates in descending order of input frequency when pictograms are selected. Image: Displays image input candidates in descending order of input frequency when pasting images. Display decoration: Display decoration candidates in descending order of input frequency when setting decoration. Note that in this embodiment, when the time zone (transmission time zone) is used as additional information for e-mail, the time zone is subdivided. There is no need to divide the time into seconds. For example, as described in the first embodiment, the day can be divided into two sections of day and night, or divided into four sections of morning / day / night / midnight. Or you may. At this time, the time zone widths do not necessarily have to be equal.

However, if the e-mail input operation is started immediately before the time zone division boundary, the time zone may be changed during the input operation. In this case, the input candidate in the time zone before the change may be a more suitable input candidate. So, for example, the time zone unit is 2 hours, and all the time zones including 2 hours before and after the input work time (the time from the input start time to the end time) are saved together with the second data. Also good. Since it is considered that the input work does not exceed 2 hours, it is not necessary to change the input candidate even if the time zone includes two hours before and after the input work time, even if the time zone is crossed during the input work. .
(2-3) Other examples of this embodiment (2-3-1) In this embodiment, the input frequency of the second data is counted using, for example, a counter, but the count is simply repeated. As the counter value overflows, the counter value will not overflow.

Therefore, for example, a data frame for a plurality of days (for example, 7) is provided for counting the input frequency of the second data, the input frequency of each corresponding day is stored in each data frame, and the next corresponding day In such a case, it is possible to subtract the number of inputs on the old corresponding day and add the number of inputs on the new corresponding day. Specifically, it has 7 data frames from Sunday to Saturday, and when it comes to the next Sunday, it subtracts the number of entries entered on the previous Sunday, and the entry entered on the new Sunday there. Add a number.
(2-3-2) In the present embodiment, at least the following two types are conceivable as a format for storing the second data, the time zone, and the input frequency.
(X) A format including a table for storing the second data itself and the input frequency for each classification Title / day: Axxx (frequency), Bxxx (frequency), Cxxx (frequency),...
Title / Night: Bxxx (Frequency), Dxxx (Frequency), Exxxx (Frequency), ...
Text / Daytime: Axxx (Frequency), Exxx (Frequency), ...
Body / Night: ..., ..., ..., ...
(Y) A format including a table for storing the second data and ID (Index) collectively, and a management table for holding the ID and input frequency of the second data for each classification Data: Axxx (Aid), Bxxx (Bid), Cxxx (Cid), ...
Title / Daytime: Aid (frequency), Bid (frequency), Cid (frequency), ...
Title / Night: Bid (Frequency), Did (Frequency), Eid (Frequency), ...
Body text / daytime: Aid (frequency), Eid (frequency), ...
Body / Night: ..., ..., ..., ...
Since a character string or the like requires a larger storage capacity than an ID, the latter (y) can reduce the storage capacity when storing a large amount of information.
(2-3-3) In the present embodiment, the thesaurus (synonyms) may be collected for the second data, and the input frequency of the second data may be determined (for example, “coming soon” and “ If "Soon" was entered once each, the frequency of each entry would be set twice).
(2-3-4) In the present embodiment, when a plurality of first data is included in the first input area (for example, when a plurality of destinations are included), the first input area is changed according to the combination of the first data. The input candidates for the second data may be changed (for example, for each first data, the corresponding second data is extracted, and only the second data common to both is used as the input candidate).
(2-3-5) In the present embodiment, the second data and its input frequency may be classified according to the contents of the input work such as reply and transfer. In that case, the storage unit 100 stores the second data together with the input frequency for each input work content, and the control unit 200 sets the second data as input candidates according to the input frequency for each input work content. indicate.
(2-3-6) The present embodiment is not limited to a device that operates by connecting to another device (such as a base station), such as a mobile terminal device such as the mobile phone described in the first embodiment, and is independent. The present invention can also be applied to a device (for example, a game machine) that operates in the above.
(2-3-7) In this embodiment, as described in the first embodiment, the user can edit input candidates for the second data to be input to the second input area. is there. In that case, the control unit 200 displays an editing screen, and updates the second data stored in the storage unit 200 to the data input on the editing screen.

  The method performed by the data input device of the present invention may be applied to a program for causing a computer to execute. In addition, the program can be stored in a storage medium and can be provided to the outside via a network.
