Description

  The present invention relates to a portable information terminal that can improve operability in a portable information terminal having a character input function.

There is a character input method that simplifies character input (see, for example, Patent Document 1). A portable information terminal to which this character input method is applied includes a plurality of reply message sentence candidates that are often used as a reply message when creating a reply mail for a received mail. When a reply mail is created, a plurality of reply message sentence candidates are displayed, and the user can create a message simply by performing an operation of selecting from the plurality. This saves the trouble of inputting and manipulating the message characters one by one.
Japanese Patent Laid-Open No. 9-222952 (page 3, FIGS. 2 to 4)

  In the conventional portable information terminal described in Patent Document 1, there are a plurality of reply message sentence candidates, but the candidates are fixed. Therefore, depending on the contents of the received mail, there is a problem that it cannot be used as a reply message sentence candidate. Further, there is no description for improving operability with respect to normal character input.

  An object of the present invention is to provide a portable information terminal with improved operability with respect to creation of a reply message and normal character input.

  In order to achieve the above object, the portable information terminal of the present invention stores a display order of operation input means for character input, display means for displaying characters, and kana-kanji conversion candidates for the first character.

Display control means for displaying the conversion candidates in the display order stored in the second display order storage means when the conversion candidates are displayed in the displayed display order and the second and subsequent characters are input after the conversion of the first character is confirmed. When the selection is made from the conversion candidates displayed by the display control means, the display order of the selected characters is increased and stored in the first display order storage means or the second display order storage means. Memory control means Characterized by including the.

  Further, the portable information terminal of the present invention includes a selection input means for character selection, a display means for displaying characters, a response character storage for storing a tail character used at the end of an email and a response character group corresponding to the tail character. And a reply mail for the received mail, and when the mail is activated, extract the last character of the received mail body, display the response character group corresponding to the last character, and within the response character group Reply mail means for determining the response character selected by the selection input means as the body of the reply mail.

  According to the present invention, it is possible to improve operability with respect to creation of a reply message and normal character input.

  FIG. 1 is a configuration diagram of a portable information terminal according to each embodiment of the present invention. The portable information terminal 100 includes an operation key 1, a display unit 2, a conversion candidate display order memory 3 for the first character when executing the mail application, a conversion candidate display order memory 4 for the second and subsequent characters when executing the mail application, and a schedule application.

  The operation key 1 has a character input key, a cursor key, a confirmation key, and the like. The display unit 2 is a display unit configured by an LCD or the like. The conversion candidate display order memory 3 is a memory for storing the conversion candidate display order for the first character when performing kana-kanji conversion when executing the mail application. The conversion candidate display order memory 4 is a memory for storing the conversion candidate display order for the second and subsequent characters when performing kana-kanji conversion when executing the mail application. The conversion candidate display order memory 5 is a memory for storing the conversion candidate display order for the first character when performing kana-kanji conversion when executing the schedule application. The conversion candidate display order memory 6 is a memory for storing the conversion candidate display order for the second and subsequent characters when performing kana-kanji conversion when executing the schedule application.

  The antenna 7 and the communication control unit 8 control wireless communication with a base station (not shown). The kana-kanji conversion dictionary 9 stores conversion candidate groups for kana-kanji conversion. The control unit 10 performs overall control of the portable information terminal 100, and in particular, performs kana-kanji conversion processing related to the present invention. The response character candidate memory 11 is a memory that stores response character candidates for reply mail related to the end sentence of the received mail when creating a reply mail for the received mail.

FIG. 2 is an explanatory diagram of a conversion candidate display order memory when executing a mail application of the portable information terminal according to the first embodiment of the present invention, and (a) is an explanatory diagram of the conversion candidate display order memory 3 for the first character. (B) is explanatory drawing of the conversion candidate display order memory 4 for the 2nd character and after.
The conversion candidate display order memory 3 for the first character in (a) is a memory for storing the characters determined to be converted as the first character at the time of character input so that they are ordered in the higher order of the candidate group in the newest history order. For example, “Thank you” for the input character “A” by the operation key is the result of the history order confirmed as the first character in the kana-kanji conversion for character input in the mail application, and is stored first. Is done. In FIG. 2, the character that has been confirmed to be converted as the first character is shown with “”, but the parenthesis “” is not displayed. Other than "Thank you", morning, tomorrow, tomorrow, meet later, let's meet, let's play. These “Thank you” are displayed as conversion candidates in the order of morning, tomorrow, tomorrow, later, meet, play,.

  Similarly, with respect to the input character “I” by the operation key, “Okay, no, go, do not go”, for example, indicates the history order in which conversion is confirmed as the first character. Subsequently, other conversion candidates are also displayed. In addition, as an example, for the input character “U” by the operation key, “UN” indicates the history order in which conversion is confirmed as the first character. Subsequently, other conversion candidates are also displayed. In addition, for the input character “ha” by the operation key, “Yes” indicates, for example, the history order in which conversion is confirmed as the first character. Subsequently, other conversion candidates are also displayed.

  The conversion candidate display order memory 4 for the second and subsequent characters in (b) stores the characters determined to be converted for the second and subsequent characters at the time of character input so that the characters are ordered in the higher order of the candidate group in the history order. It is. As an example, for the input character “A” by the operation key, the morning, tomorrow, the day after tomorrow, thank you, later, meet, play, etc. are stored in the order of the history of conversion confirmation.

  Similarly, for the input character “I” by the operation key, as an example, now, when, say, go, have, no, house,. Shows the history order. In addition, as an example, for the input character “U” by the operation key, “happy”, “meeting”, “launching”, “yes”, “up”, “back”,. In addition, for the input character “ha” by the operation key, for example, the history order in which the conversion is confirmed as the second and subsequent characters, for example, talk, nice to meet, yes, first, early, early rise, start, belly,. Show.

  When inputting characters using a limited number of operation keys, such as a portable information terminal, compared to keyboard operations such as a personal computer, the first character is often short and the first character can be used. , The character system used tends to be different. Therefore, when the first character is input, the conversion operability can be improved by displaying the conversion candidate for the first character at the top of the candidate group.

  The characters that have been confirmed to be converted are stored so as to be ordered higher in the candidate group in the order of the latest history, but may be stored so that they are ordered in the upper order of the candidate group in the order of characters that are frequently converted. Good.

FIG. 3 is an explanatory diagram of the conversion candidate display order memory when executing the schedule application of the portable information terminal according to the first embodiment of the present invention. FIG. 3A is an explanatory diagram of the conversion candidate display order memory 5 for the first character. (B) is explanatory drawing of the conversion candidate display order memory 6 for the 2nd character and after.
The difference from FIG. 2 is that the performance of the character used as the first character is different because the application to be executed is different. As in the conversion candidate display order memory 3 (FIG. 2), the conversion candidate display order memory 5 for the first character in FIG. It is a memory that stores data so as to be ordered higher. As an example, “tomorrow, tomorrow, morning”, which is confirmed to be converted as the first character, is different from FIG. Further, as an example, “Meeting and driving” is different from FIG. 2 for the input character “U” by the operation key. Further, as an example, the input character “ka” by the operation key is a history in which “conference, holding, school” is converted and confirmed as the first character.

  Similarly to the conversion candidate display order memory 4 (FIG. 2), the conversion candidate display order memory 6 for the second and subsequent characters shown in FIG. The memory stores data in order so as to be higher in the candidate group. In practice, the history is different from that of the conversion candidate display order memory 4 (FIG. 2).

  FIG. 4 is an operation flowchart of kana-kanji conversion of the control unit of the portable information terminal according to the first embodiment of the present invention. The control unit 10 confirms the application being executed (step S1). If it is a mail application, the conversion candidate display order memory 3 is designated for the first character, and the conversion candidate display order memory 4 is designated for the second and subsequent characters. If it is a schedule application, the conversion candidate display order memory 5 is designated for the first character, and the conversion candidate display order memory 6 is designated for the second and subsequent characters (step S2). Thereafter, kana-kanji conversion processing is performed using the designated memory. As an example, the case of a mail application will be described below.

  First, the character input key is checked (step S3). If the character input key is pressed, the process for the first character is started. The corresponding character input and conversion candidate order in the conversion candidate display order memory 3 for the first character are displayed on the display unit 2 (step S4). Then, the candidate designated by the cursor key is displayed as a cursor (step S5), and the confirmation key is checked (step S6). When the confirmation key is pressed, the candidate displayed by the cursor is displayed in the text display field of the display unit 2 (step S7). Then, the display order of the determined candidates is increased and stored in the conversion candidate display order memory 3 for the first character (step S8). This completes the process for the first character.

  The next character input key is checked again (step S9) and the confirmation key is checked (step S10). If the confirmation key is pressed at that time, the kana-kanji conversion process ends (step S20). If the character input key is pressed in step S9, the process for the second and subsequent characters is entered. The corresponding character input and conversion candidate order in the conversion candidate display order memory 4 for the second and subsequent characters are displayed on the display unit 2 (step S11). Then, the candidate designated by the cursor key is displayed as a cursor (step S12), and the confirmation key is checked (step S13). When the confirmation key is pressed, the candidate displayed by the cursor is displayed in the text display field of the display unit 2 following the first character (step S14). Then, the determined candidate display order is increased and stored in the conversion candidate display order memory 4 for the second and subsequent characters (step S15).

  Further, the next character input key is checked (step S16) and the confirmation key is checked (step S17). If the character input key is pressed, step S11 and subsequent steps are repeated. If the enter key is pressed in step S17, the kana-kanji conversion process ends (step S20).

  According to the first embodiment of the present invention, it is possible to improve the operability when inputting the first character by providing the memory for storing the display order of the character conversion candidates for the first character and the second and subsequent characters. In particular, it is possible to improve the operability of character input of a portable information terminal that has few operation keys and is not very operable.

  In addition, although the memory which memorize | stores the display order of each character conversion candidate for the first character and for the second and subsequent characters is provided for each application to be executed, it may not be divided for each application. In addition, the memory for storing the display order of the character conversion candidates for the second and subsequent characters is not particularly provided for the second and subsequent characters, and there is a memory for storing the display order when performing normal kana-kanji conversion. You may use it.

  FIG. 5 is an explanatory diagram of the response character candidate memory of the portable information terminal according to the second embodiment of the present invention. The response character candidate memory 11 registers response character candidates for the first character of the reply mail with respect to keywords that are likely to be used at the end of the received mail. For example, for the received mail tail keyword “?”, “Yes, Yes, No” of affirmative and negative sentences are registered as response character candidates. For the received mail tail keyword “go?”, “Go, do not go”, which is a positive and negative sentence, is registered as a response character candidate. For the keyword “thank you” at the end of the received mail, “Thank you, please come again,” which is a common answer / answer candidate, is registered.

  FIG. 6 is an operational flowchart of reply mail creation of the control unit of the portable information terminal according to the second embodiment of the present invention. The control unit 10 receives the mail (step S31). The content is, for example, “Go today?” When the user performs a reply mail operation, the control unit 10 activates a reply mail editing screen (step S32). Next, the control unit 10 extracts “?” And “go?” As keywords from the end of the received mail (step S33). Then, the response character candidate memory 11 is searched for response character candidates of reply mails for the keywords “?” And “go?”, And “yes, yes, no” and “go, do not go” are detected (step S34). ). All of these are displayed (step S35).

  Next, the character input key is checked (step S36). If there is no character input key operation, cursor designation and confirmation key operation for any of “Yes, Yes, No, Go, Do Not Go” displayed as a response character candidate The character designated by is determined and displayed as a reply mail (step S37). Next, if there is no other key operation (step S38), steps S35 to S37 are repeated, and all the necessary characters in “Yes, yes, no, go, do not go” displayed as response character candidates are extracted. As a result, for example, “Yes, go” can be created as a reply mail only by cursor designation and confirmation key operation.

  If there is another key operation in step S38, the reply mail creation by the response character candidate is finished, and the next process is started (step S40). If there is a character input key operation in step S36, the text creation by the response character candidate is terminated and the character input by the normal character input key is started (step S39). If the end of the received mail extracted in step S33 is “Thank you”, the response character candidate display in step S35 will display “Thank you again, OK again”.

  According to the second embodiment of the present invention, since the response character candidate group of the first character of the reply mail corresponding to the end of the received mail is automatically displayed, the user only needs to select it, so that the character input The operability can be improved.
