Description

  The present invention relates to a character input conversion device, a character input conversion method, a personal computer, an information communication portable terminal, and a program, and more particularly to a character input conversion device, a character input conversion method, and the above-described character input suitable for character conversion of many types of characters. The present invention relates to a personal computer or an information communication portable terminal provided with a conversion device, a personal computer using the above-described character input conversion method, an information communication portable terminal, or a program.

  As a character input method for personal computers, personal digital assistants (PDAs), mobile phones, and the like, an input method using a keyboard is generally used. In the case of a language with many types of characters such as Japanese, it is physically difficult to equip keys corresponding to all types of characters. Normally, a character input method is employed in which “kana character string” or “Roman character string” is selected, characters are input from a keyboard, and “character conversion” is performed on the input characters.

  In recent years, mobile phones are equipped not only with a call function but also with special functions having high utility value such as a telephone book, electronic mail, a schedule, and a memo pad. Due to the size limitation due to portability, the mobile phone includes a numeric keypad instead of a keyboard as an input device, and characters are input from the numeric keypad. Japanese character input on a mobile phone has many types of characters, and because it is a character input using a numeric keypad, the number of character input operations is very large and input errors are likely to occur. (Character entry) is a big burden.

  Patent Document 1 below discloses a character string input device and method that can reduce the burden of character input operation on the user of a mobile phone. As shown in FIG. 10, a character string input device 1 disclosed in Patent Document 1 includes an input unit 2, an input situation acquisition unit 3, a situation control unit 4, a situation optimization dictionary 5, and candidate character string generation. Part 6, candidate character string confirmation part 7, and confirmed character string registration part 8. Each of the input status acquisition unit 3, candidate character string generation unit 6, and candidate character string determination unit 7 is connected to the character string processing device 9.

  The operation of this character string input device 1 is as follows. First, when a character string is input to the character string processing device 9, the character string is sent to the candidate character string generation unit 6 through the input unit 2. When the character string processing device 9 is activated and a character is input, the input status acquisition unit 3 acquires the input status from the character string processing device 9.

  Here, the “input status” is what the character string processing device 9 is (for example, a schedule input device, an e-mail input device, etc.), and what is the document targeted by the character string processing device 9. This means a situation at the time of input such as which position in the document (for example, the destination mail address part). For example, when the schedule input device is activated as the character string processing device 9, the schedule input device notifies the input status acquisition unit 3 of information that the schedule input device is selected as the character string processing device 9. . The input status acquired by the input status acquisition unit 3 is sent to the status control unit 4. The situation control unit 4 sets a candidate character string generation state according to the input situation based on the acquired input situation.

  Here, the “candidate character string generation state” means that the situation optimization dictionary 5 is changed according to the input situation, or the generation method of the candidate character string is changed according to the input situation. For example, the situation optimization dictionary 5 selected while inputting a schedule is a dictionary in which a character string is input and registered in the character string processing device 9 used to input the schedule previously. The candidate character string generation unit 6 generates an optimal candidate character string using the situation optimization dictionary 5, and this optimal candidate character string is sent to the character string processing device 9. For example, when “KAIGI” is entered, the situation optimization dictionary 5 used for character conversion selects a dictionary for schedule input. Therefore, a character input person frequently enters the schedule input as the first candidate character. Adopt “conference” as the input character with high priority.

  The optimum candidate character string sent to the character string processing device 9 is output to an output unit (for example, a display unit) in the character string processing device 9. The character input person issues a confirmation instruction from the candidate character string confirmation unit 7 to the output candidate character string. In the candidate character string confirmation unit 7, the confirmed candidate character string is sent to the situation control unit 4. The situation control unit 4 sends the current input situation and the confirmed character string to the confirmed character string registration unit 8. Then, the confirmed character string registration unit 8 registers the confirmed character string in the situation optimization dictionary 5 according to the current input situation.

In this character string input device 1, the character conversion dictionary used for character conversion can be optimally controlled in accordance with the input status of the character input person, so that the character conversion accuracy can be improved. “Improving the accuracy of character conversion” means an improvement in the probability that a converted character string desired by a character input person will be adopted as a character conversion candidate, and an improvement in the probability of being adopted as a higher character conversion candidate. By improving the character conversion accuracy, the number of operations by the character input person can be reduced.
JP 2000-315204 A

  However, in the above-described character string input device 1 and the method thereof, the following points have not been considered. For example, when composing an e-mail, if a character input user enters “Today will hold a meeting on January 1” and wants to input the same character string by e-mail the next day, the character conversion dictionary Selects the most suitable dictionary for the existing input situation, and therefore, the conversion character is a character string “Today will hold a meeting on January 1” as a candidate character string. That is, even though today is “January 2”, “January 1” is selected as a candidate character string, and the character input person deletes the part “January 1”, Since it is necessary to correct and input “January 2” in the deleted portion, an extra character input operation occurs. This is due to the fact that only the input state of the existing character string is focused and the optimum character conversion candidate is generated. As a result, the number of operations by the character input person increases, and the character input operation becomes a burden. turn into. In addition, an increase in the number of operations induces a character input error, and the character input operation becomes a burden from this point.

  The present invention has been made in view of the above points, and can improve the accuracy of character input conversion, reduce the number of character input operations, and reduce the burden of character input operations.

(Embodiment 1)
Embodiment 1 of the present invention relates to a character input conversion device, a character input conversion method, a personal computer, an information communication portable terminal, and a program for performing character conversion or predictive conversion of characters according to the date / time situation (date information) at the time of character input Is described.

[Configuration of Character Input Conversion Device, Personal Computer, and Information Communication Portable Terminal]
As shown in FIG. 1, a character input conversion device 10 according to Embodiment 1 of the present invention includes a character input unit 11 for inputting characters to be converted, which are output from a character string processing device 20, and a character input unit. A date / time status storage unit 13 for storing date / time status such as at least date / time, day of the week, etc., and situation-considered characters that perform character conversion or predictive conversion of characters in accordance with the stored date / time status and create a conversion candidate list for the converted characters A prediction conversion unit 12 and a character selection determination unit 14 for determining conversion characters in the conversion candidate list are provided. Here, in the first embodiment and the embodiments described later, “character” is used to mean at least one character, and “character string”, which is a plurality of characters that are continuously input, is “character”. Included in the concept.

  The character string processing device 20 is an application for inputting characters. For example, an application such as a schedule book or a mailer for creating an e-mail can be practically used for the character string processing device 20.

  The character input conversion device 10 and the character string processing device 20 are incorporated into a word processor of a personal computer, or an information communication portable terminal such as a mobile phone or a personal digital assistant (PDA).

  The date / time status storage unit 13 is built in the character input conversion device 10 in the first embodiment. Note that the date / time situation storage unit 13 can use a part of a memory built in, for example, a personal computer or an information communication portable terminal in which the character input conversion device 10 is incorporated. As the memory, a volatile memory such as a dynamic random access memory (DRAM) or a static random access memory (SRAM) can be practically used. Therefore, the date / time situation storage unit 13 is not limited to being built in the character input conversion device 10, and may be constructed as an external device of the character input conversion device 10.

[Character input conversion method]
Next, using FIG. 1 and FIG. 2, the operation of the character input conversion device 10 will be described, and the character input conversion method will be described together.

  First, as shown in step S <b> 1 of FIG. 2, “character” (or “character string”) converted from the character processing device 20 is input to the character input unit 11 of the character input conversion device 10. As shown in step S <b> 2, the situation-considered character prediction conversion unit 12 performs prediction conversion of “character” on the input “character”.

  As shown in step S <b> 3, it is determined whether or not there is a “character” regarding the date and time situation that changes every moment in the “character” that has undergone prediction conversion. As a result of the determination, if there is no “character” representing the date and time situation, general “character” predictive conversion is performed, and a conversion candidate list is generated as shown in step S6. Here, the prediction conversion of “character” means that character conversion including prediction conversion such as “tomorrow”, “morning”, and “a” is performed as a conversion candidate list when “a” is input, for example. used.

  On the other hand, in the determination shown in step S3, if there is a “character” representing the date / time situation, the processing according to the first embodiment is performed. That is, as shown in step S4, the date / time situation (date / time information) is acquired from the date / time situation storage unit 13 of the character input conversion device 10, and the prediction conversion of “character” is performed using this date / time situation as shown in step S5. I do. The prediction-converted “character” is generated as a conversion candidate list as shown in step S6. The predictive conversion of “character” in accordance with the date / time situation is “at the time of character input”, and in the first embodiment, this “at the time of character input” means that the user (character input person) actually sends the character processing device 20. Is used to include at least the period from the moment when "character" is input to the time immediately before the conversion candidate list shown in step S6 is created.

  As shown in step S7, the character selection confirmation unit 14 can select and confirm the conversion character desired by the user from the conversion candidate list. Here, when it is not desired to convert the input character, as in a general character input conversion device, character input is continuously performed as shown in step S1.

  The confirmed converted character is displayed on the display device (see FIG. 4) of the character string processing device 20. Further, the confirmed converted character is sent to the situation-considered character prediction conversion unit 12, and as shown in step S8, a learning process for increasing the priority of the converted character confirmed in the situation-considered character prediction conversion unit 12 is performed.

Next, the operation of the character-considering character prediction conversion unit 12 of the character input conversion device 10 will be described in detail.
As illustrated in FIG. 3, in the character string processing device 20, for example, when an input character 30 of “Kyo” is input, a conversion candidate list 31 is generated as a result of predictive conversion. The conversion candidate list 31 has a high priority such as “1. X / Y / Z”, “2. Today”, “3. Y month Z day of X”,. This is a list in which conversion candidate characters (or character strings) are arranged in order. Here, the variables “X”, “Y”, “Z”, “A”, “B”, “C” are the date and time situations “year”, “month”, “day”, “day of the week”, “ It represents hours and minutes. “2. Today” is normal character conversion (kanji conversion).

  When such a variable representing the date / time situation exists in the conversion candidate list 31, the date / time situation 50 is acquired from the date / time situation storage unit 13. The date / time situation 50 includes at least information of year, month, day, day of week, hour, and minute when a character is input, such as “2004/1/1, Thursday, 12:00”.

  Further, a date / time variable substitution process 32 is performed according to the input character, and the information obtained from the date / time situation 50 is associated with the variable to generate the character candidate list 33. In the character conversion candidate list 33, the date / time status 50 is substituted into the conversion candidate list 31, and “1.2004 / 1/1”, “2. Today”, “3. The conversion candidate characters are arranged in descending order of priority, such as “8.12: 00”.

  Further, in the character string processing device 20, for example, when the character input 40 “Kino” is input, a conversion candidate list 41 is generated as a result of the prediction conversion. The conversion candidate list 41 is similar to the conversion candidate list 31, and is “1. X / Y / Z”, “2. Yesterday”, “3. Y month Z day of X”,. This is a list in which conversion candidate characters are arranged in descending order of priority, such as “C minutes”. If there is a variable representing the date / time situation in the conversion candidate list 41, the date / time situation 50 is acquired from the date / time situation storage unit 13. This date / time situation 50 is the same as the date / time situation 50 when the character candidate list 33 is generated. For example, the year, month, day, and the like when inputting characters such as “2004/1/1, Thursday, 12:00” Includes at least information on the day of the week, hour, and minute. Furthermore, a date / time variable substitution process 42 is performed in accordance with the input character, and the information obtained from the date / time situation 50 is associated with the variable to generate the character candidate list 43. In the character candidate list 43, the date / time status 50 is substituted into the conversion candidate list 41 and “Yes”, and therefore “1” is calculated from the information corresponding to the day and the information corresponding to the day of the week in the date / time variable substitution process 42. Subtraction, the conversion candidate characters are arranged in descending order of priority, such as “1.2003 / 12/31”, “2. Yesterday”, “3. 31 December 2003”,. Has been.

  As shown in FIG. 4, the display device 21 of the character string processing device 20 shows a display example when the character input 40 “Kino” is performed. The display device 21 is specifically a liquid crystal display device (or an organic electroluminescence display device or a plasma display device) of a mobile phone. Each of “December 31”, “12/31”, and “12/31 (Wednesday)” displayed on the display device 21 is a conversion candidate of “character” that changes according to the time and date situation that changes every moment. is there.

  FIG. 5 shows an example of the conversion character corresponding to the input character including the above example. In FIG. 5, the conversion character enclosed in square brackets is a conversion character whose variable changes according to the date and time situation that changes every moment.

  Further, in the description of the character input conversion method, the description is made on the premise of hardware. However, each process of steps S1 to S8 shown in FIG. 2 is performed by a computer program and realized as software. Also good.

  In such a character input conversion device 10 and a character input conversion method, the date and time status at the time of character input that changes every moment is stored in the date and time status storage unit 13, and according to the stored date and time status at the time of character input, Since character conversion or predictive conversion of characters can be performed, it is possible to improve character conversion accuracy, reduce the number of character input operations, and reduce the burden of character input operations.

For example, when the current weather (at the time of character input) is “sunny”, the temperature is “30 ° C.”, and the humidity is “70%”, the character input conversion device 10 displays “ONDO” as shown in FIG. When such a character is input, a conversion candidate list such as “30 ° C.” and “temperature (“ 30 ° C. ”)” can be generated. When a character such as “Kyoha” is input, a conversion candidate list such as “Today is“ hot ”” and “Today is“ Sunny ”” can be generated. Further, when a character such as “Shitsudo” is input, a conversion candidate list such as “70%” and “humidity (“ 70% ”)” can be generated. In FIG. 7, the conversion characters enclosed in square brackets are conversion characters whose variables change according to the weather conditions that change every moment.

  Note that the character input conversion method according to the second embodiment is substantially the same as the character input conversion method according to the first embodiment, and it is determined whether or not there is a date / time situation corresponding character shown in step S3 of FIG. Instead of determining whether there is a character corresponding to the weather situation, the acquisition of the date / time situation shown in step S4 is replaced with the acquisition of the weather situation, and the situation-considered character prediction conversion shown in step S5 is the situation-considered character prediction conversion corresponding to the weather situation. Therefore, the description is omitted here.
