Description

  The present invention relates to an electronic device that can perform conversion into characters including emotion information.

An electronic device such as a mobile phone having a display unit and a key input unit has a function of creating a sentence such as mail creation among a plurality of functions of the electronic device.
When creating a sentence using such an electronic device, it is usually confirmed on the display unit of the electronic device step by step that the characters entered on the key input unit are converted into appropriate characters. Is called. And the confirmation is repeated and the sentence which should be created is completed.

  Here, in order to improve the ease of transmission of the created sentence to the reader, there are cases where characters including emotion information are included in the sentence. Here, characters including emotion information include symbols, pictograms, etc. in addition to kana-kanji numerals. On the other hand, characters entered at the key input unit are usually based on kana. Therefore, when converting into a character including emotion information based on the character input by the key input part, it is necessary to perform the conversion efficiently.

  Therefore, in the “animation selection apparatus and method” disclosed in Patent Document 1, the character input to the key input unit is associated with a predetermined word, thereby converting the character into an animation that expresses the user's emotion. Can be selectively performed without complicated operations.

  In the “emotion expression method in a text message” disclosed in Patent Document 2, when a key of the key input unit is pressed for a long time when a character is input by the key input unit, the character related to the pressed key is determined. A plurality of text parameters are displayed on the display unit. Then, the user is allowed to select one of the plurality of text parameters displayed on the display unit. Furthermore, animation processing is automatically performed on the selected text message, the message is visually emphasized, and emotions are included.

  In the “character input device” disclosed in Patent Document 3, an independent word of a received mail and a character string of a reply mail that has already been transmitted are associated by the same ID. Then, an independent word corresponding to the character string input by the key input unit when the reply mail is created is set as a conversion prediction candidate so that the reply character of the received mail can be smoothly input.

  In the “character input device and character input device program” disclosed in Patent Document 4, in order to make a character string composed of expressions that the user wants to input higher in the conversion prediction candidates, the contents and context of the document being input are used. The optimum context dictionary can be selected accordingly.

  Conventional electronic devices generally require an input operation to include emotion information each time it is converted into characters including emotion information based on characters input by a key input unit. For this reason, in conventional electronic devices, the efficiency of converting characters input at the key input unit into characters including emotion information is low, and convenience is not necessarily high.

In addition, in the method of the cited documents 1 and 2, the operation | work converted into the animation which expresses an emotion is simple. However, the converted animation does not necessarily reflect the user's emotions, and it is difficult to appropriately include emotion information in the created text.
Moreover, in the apparatus of the cited document 3, emotion information can be included in the created text only for the character string associated with the ID assigned to the phrase in the received mail. Moreover, it is limited to the text of a reply mail that emotional expressions can be included in the text. Therefore, emotion information cannot be included in the created text in general text creation other than reply mail.
Furthermore, in the apparatus of the cited document 3, the user's emotion is not necessarily reflected in the word that is the conversion prediction candidate.
In addition, since the apparatus of cited document 4 only selects the context dictionary, emotion information cannot be included in the created document.

  In view of the above circumstances, the problem to be solved by the present invention is that there is no need for an input operation to include complicated emotion information, and the efficiency of converting input characters into characters including appropriate emotion information is high. It is to provide an electronic device that is high and convenient.

The electronic device according to the present invention includes a character input unit that accepts character input, an emotion character discrimination table that stores correspondences between emotion IDs and characters classified according to the type of emotion, and input by the character input unit. When the input character is a character stored in the emotion character discrimination table, an acquisition unit that acquires the emotion ID corresponding to the input character, and a character corresponding to the acquired emotion ID As a prediction conversion candidate for the input character obtained from the database, the display unit for displaying the acquired character, and the input character input in the character input unit is not the character stored in the emotion character discrimination table, In the case where the input character and the previous character input last time can be a single clause, and the previous character is a character to which the emotion ID is assigned, the input character The last character as one of clauses, comprising a deposition unit that imparts emotion ID of the last character as ID of該文clause, wherein the display unit, the predicted characters corresponding to granted emotion ID to the clause obtained from the conversion candidate database, as a prediction conversion candidates for the input character, that displays preferentially the obtained character.

  Preferably, in the electronic device according to the present invention, when the input character input by the character input unit is not a character stored in the emotion character determination table, the acquisition unit displays an emotion as an ID corresponding to the input character. When an ID indicating that the character is not a character to be acquired is acquired and the ID indicating that the character is not an emotion is given as the ID, the prediction conversion candidate corresponding to the input character from the prediction conversion candidate database And the acquired characters are displayed in the order shown in the predictive conversion candidate database.

  More preferably, the electronic device of the present invention includes an updating unit that stores a correspondence relationship between the clause and the emotion ID assigned to the clause in the emotion character discrimination table.

In the electronic device of the present invention, the adding unit may make the input character and the previous character input last time as one phrase when the last input character does not end with a punctuation mark or a line feed character. Judge that you can.
Preferably, in the electronic device of the present invention, the type of emotion includes at least one of happy, angry, sad and fun.
Incidentally, the predictive conversion candidate database, it is not to desired character with the potential following the input character is stored.

  The electronic device of the present invention is highly efficient and convenient for converting input characters into characters including appropriate emotion information.

Hereinafter, the portable terminal 1 will be described as an example of the electronic apparatus of the present invention.
FIG. 1 is a perspective view of the mobile terminal 1. The mobile terminal 1 has an operation unit 2 and a display unit 3.
The operation unit 2 has keys to which various functions are assigned such as a power key, a call key, a numeric key, a character key, a direction key, a determination key, and a call key, and these keys are operated by the user. If so, a signal corresponding to the operation content is generated, and the signal is output to the control unit in the portable terminal 1.

The display unit 3 is configured using, for example, a liquid crystal display (LCD) or an organic EL (OLED) display, and displays an image corresponding to a video signal supplied from the control unit.
The image displayed on the display unit 3 is, for example, a destination telephone number at the time of outgoing call, a telephone number of the outgoing call source at the time of incoming call, contents of text of received mail or outgoing mail, date, time, remaining battery level, standby image There is.

FIG. 2 is a block diagram relating to the configuration of the mobile terminal 1 shown in FIG.
Here, the present invention is characterized by a function of creating a sentence having characters including emotion information by operating the operation unit 2 of the portable terminal 1 shown in FIG. Therefore, only the configuration necessary for realizing the function is shown in FIG. That is, the block diagram shown in FIG. 2 realizes a voice call function, a mail transmission / reception function, a web browsing function, and the like other than the functions necessary for creating a sentence having characters including emotion information in the mobile terminal 1. Therefore, the configuration necessary for this is omitted.

Further, among the functions for creating a sentence, a configuration for realizing a basic function for converting characters input by the operation unit 2 into appropriate characters (normal kanji, numbers, proper nouns, etc.) is also omitted. doing. That is, this function is a normal kana-kanji conversion function for creating a normal sentence composed of kana, kanji, numbers, etc. in a personal computer, a word processor, and a mobile phone.
Therefore, the normal kana-kanji conversion function is regarded as a function well known to those skilled in the art, and the configuration for realizing the function is omitted. For the above reason, in the block diagram shown in FIG. 2, only a configuration for realizing a function of converting a character input by the operation unit 2 into a character including emotion information is shown.

In the block diagram shown in FIG. 2, in the portable terminal 1, the control unit 4, the display unit 3 connected to the control unit 4, and the character input unit 2a connected to the control unit 4 (the operation shown in FIG. Corresponding to one of the functions of the section 2).
An information processing unit 5 for realizing a function of actually creating a sentence having characters including emotion information based on the control of the control unit 4 is connected to the control unit 4.

  Here, the information processing unit 5 includes an emotion character determination table 6 and a prediction conversion candidate database 8. In addition, the information processing unit 5 includes an update unit 10 that appropriately updates the emotion character discrimination table 6 and the prediction conversion candidate database 8. Furthermore, the information processing unit 5 includes an emotion phrase determination unit 11.

  On the other hand, the control part 4 has the acquisition part 7 which acquires emotion ID, and the provision part 9 which provides emotion ID with respect to a phrase.

  The control unit 4 and the information processing unit 5 can be realized, for example, by appropriately designing a CPU (Central Processing Unit) and a memory.

  As shown in FIG. 2, the information processing unit 5 includes an emotion character discrimination table 6 that stores a correspondence relationship between characters input to the character input unit 2 a and emotion IDs classified by emotions that the characters mean. Have

Here, in order to show the configuration of the emotion character discrimination table 6 more specifically, reference is made to FIG.
In the emotion character discrimination table 6 shown in FIG. 3, among the characters input to the character input unit, predetermined characters having emotion, for example, “happy”, “angry”, “sad”, “fun”, respectively. Are associated with the classified emotion IDs “A”, “B”, “C”, and “D”. In addition, the character input into the character input unit may be a character that has the same sound and has a plurality of emotions. In such a case, for example, the correspondence is determined according to the order in which the emotion character discrimination table 6 is updated by the update unit 10 described below.
If the character input to the character input unit has no emotion, “E” is made to correspond to the “no emotion” ID for the character. Here, such a correspondence relationship is not determined uniformly, but is appropriately updated by the updating unit 10 (FIG. 2) connected to the emotion character discrimination table 6. That is, the emotion character discrimination table 6 is provided with a learning function.

  As illustrated in FIG. 2, the information processing unit 5 includes a predictive conversion candidate database 8 that stores character candidates having a possibility of being connected to the characters input to the character input unit 2 a in a predetermined priority order.

Here, FIG. 4 is referred to in order to show a more specific example of the configuration of the predictive conversion candidate database 8.
In the predictive conversion candidate database 8 shown in FIG. 4, for example, the characters “Net ☆”, “Things” that have the possibility of being connected to the character “happy” corresponding to the emotion ID “A” (can be predictive conversion candidates). ”And“ (^^) ”are stored in a predetermined order. In addition, the character “sad” corresponding to the emotion ID “C” may be stored in a character “but ...” that may be connected to the meaning, and the character “fun” corresponding to the emotion ID “D” may be connected to the meaning. Stores the character “Shi, Fun ♪”.

  If the character has no emotion (when “E” is given to the character as “no emotion”), the character (for example, “Today is Sunday” or “I did it”) is used as a predictive conversion candidate. ) And the appropriate characters “Ne.” And “Da.” Are stored.

  Here, the contents and storage order of the prediction conversion candidates stored in the prediction conversion candidate database 8 are appropriately updated by the updating unit 10 (FIG. 2) connected to the emotion character discrimination table 6. In other words, the predictive conversion candidate database 8 is provided with a learning function.

  In FIG. 2, the information processing unit 5 includes an emotion phrase determination unit 11 for determining whether or not a combination of characters input to the character input unit 2 a constitutes a phrase including emotion information. A specific method for determining whether or not to constitute a phrase in the emotional phrase determination unit 11 will be described in a later flowchart (FIG. 7).

  Further, in FIG. 2, the control unit 4 that controls the information processing unit 5 corresponds to a character input to the character input unit 2 a when the character input to the emotion character determination table 6 corresponds to the character. It has an acquisition unit 7 that gives an emotion ID and gives a “no emotion” ID when it does not correspond to a character stored in the emotion character discrimination table. Further, when the emotional phrase determining unit 11 determines that the combination of characters input to the character input unit 2a constitutes a phrase including emotional information, the control unit 4 adds an emotion ID to the phrase. Part 9.

The figure which shows the content displayed on the display part 3 of the portable terminal 1 for the flow for creating the text which has the character containing emotion information using the portable terminal 1 which has the structure as shown in FIG. 5 and steps ST0 to ST10 in the flowchart of FIG.
Here, in the flow of creating a sentence, the display unit 3 is input to the input character display unit 12 indicating the characters input to the character input unit 2a and the character input unit 2a as shown in FIG. A conversion BOX 13 indicating a candidate character to be converted corresponding to the character is displayed. The characters displayed in the conversion BOX 13 include characters related to prediction conversion candidates in addition to the character candidates converted by the normal kana / kanji conversion function.

  When a predetermined operation is performed on the operation unit 2 of the portable terminal 1, an initial screen for creating a sentence is displayed on the display unit 3 (FIG. 5A, ST0). Then, the character input unit 2a is operated to input, for example, the character “happy” (ST1). Then, the control unit 4 accesses the emotion character discrimination table 6 and checks the correspondence between the input character “happy” and the character stored in the emotion character discrimination table 6 and the emotion ID (ST2).

  Here, the input character is “happy” and matches the character “happy” in the emotion character discrimination table 6. In the emotion character discrimination table, since the emotion ID corresponding to “happy” is “A”, the acquisition unit 7 acquires the emotion ID “A” (ST3). When the input character is not “happy” or the like and the input character is a character “XXX” having no emotion, the acquisition unit 7 sets “Emotion” ID “E”. Obtain (ST3 ').

  Thus, when the acquisition unit 7 acquires the ID from the emotion character discrimination table 6, the control unit 4 accesses the learning data BOX (having the prediction conversion candidate database 8) (ST4). After accessing the learning data BOX, the control unit 4 determines whether or not the acquisition unit 7 has acquired the emotion ID (ST5). As a result of the determination, if the acquisition unit 7 has not acquired any of the emotion IDs “A”, “B”, “C”, and “D”, and has acquired “E” that is the “no emotion” ID The control unit 4 refers to the predictive conversion candidate database 8 and indicates “Ne.” And “Is.” Connected to the input characters “XXX” in the conversion box 13 according to a predetermined order (FIG. 5). (B), ST7).

  On the other hand, if the acquisition unit 7 has acquired any of the emotion IDs “A”, “B”, “C”, and “D” as a result of the determination, the control unit 4 determines that the prediction conversion candidate database 8 Referring to the characters “Nets ☆”, “There was a thing!” And “(^^)” that are candidates for predictive conversion for the input character (here “happy”) according to a predetermined order The conversion box 13 is preferentially shown with respect to the normal conversion characters (FIG. 5 (c), ST6). As a result of the determination, if the acquisition unit 7 has acquired any of the emotion IDs “A”, “B”, “C”, and “D”, the control unit 4 determines the normal character of the input character. The converted character may not be displayed on the conversion BOX 13. In addition, when the acquisition part 7 has not acquired any emotion ID, the control part 4 displays a normal conversion character on the conversion BOX13.

  In this way, simply by inputting an input character, a character that becomes a candidate for prediction conversion and includes appropriate emotion information is preferentially shown in the conversion BOX 13. Therefore, when the user converts characters including emotion information based on the characters input by the character input unit 2a, an input operation to include emotion information is not necessary. Therefore, a complicated key input operation that includes emotion information is not required, and the efficiency of converting characters input by the character input unit 2a into characters including appropriate emotion information is high and convenience is improved.

  As described above, the control unit 4 determines whether or not the acquisition unit 7 has acquired the emotion ID from the emotion character discrimination table 6. Then, according to the determination, the conversion BOX 13 indicates characters that are candidates for predictive conversion with respect to the input character according to a predetermined order. Here, a method for selecting a character to be a predictive conversion candidate will be described with reference to a flowchart of FIG. 7 different from the flowchart of FIG.

  First, the control unit 4 checks whether the acquisition unit 7 has acquired an emotion ID from the emotion character discrimination table 6 (ST11). When the acquisition unit 7 has acquired any of the emotion IDs “A”, “B”, “C”, and “D”, the control unit 4 refers to the prediction conversion candidate database 8 and acquires the acquisition unit 7 The prediction conversion candidate corresponding to the emotion ID of the same type as the emotion ID acquired by 7 is extracted from the prediction conversion candidate database 8 (ST12).

And the control part 4 selects the character group used as the prediction conversion candidate corresponding to emotion ID which corresponds to the kind of emotion ID which the acquisition part 7 acquired in the prediction conversion candidate database 8 (ST13). In addition, when the acquisition part 7 has not acquired emotion ID, the control part 4 selects the character group used as the prediction conversion candidate connected with the input character and an appropriate meaning from the prediction conversion candidate database 8 (ST13). ). The selected character group is displayed on the conversion BOX 13 (ST14).
In this way, the method for selecting a character as a predictive conversion candidate has been described with reference to the flowchart of FIG.
Hereinafter, the description returns to the flowchart of FIG.

  After the predicted conversion candidate is displayed in the conversion BOX 13, the character input unit 2 a is operated again to select the next character (next selected character) from the conversion BOX 13, or when another character is input. Think. Here, it is assumed that the character input in ST1 is “the character input last time”, and the next selected character and another character are “characters input this time”. At this time, similarly to ST5, the control unit 4 determines whether or not an emotion ID is given to the character input this time (ST8). If it is determined that an emotion ID is assigned to the character input this time, the process proceeds to ST6.

  On the other hand, when it is determined that the emotion ID is not assigned to the current character, the control unit 4 determines the character input this time and the character (character input in ST1) input last time. Emotion phrase determination is performed to determine whether or not the combination of the above can be made into one phrase (ST9).

  The emotion phrase determination will be described based on a flowchart (FIG. 8) showing a specific flow thereof. First, it is checked whether or not the last character of the previously input character is a punctuation mark or a line feed character (a character indicating a line feed) (ST21). If the last character of the last entered character is a punctuation mark or a new line character (No), the combination of the currently entered character and the last entered character does not constitute a clause, so the emotional clause The determination flow ends.

  If the last character of the previously input character is not a punctuation mark or a line feed character (Yes), the emotion ID “A”, “B”, “C”, “ It is checked whether any of “D” has been acquired (see ST3) (ST22). If any of the emotion IDs “A”, “B”, “C”, and “D” has not been acquired for the previously input character (No), the previously input character is input this time. Since the phrase combined with the written character does not include emotion, the emotion phrase determination flow is terminated.

  If any of emotion IDs “A”, “B”, “C”, and “D” has been acquired for the previously input character (Yes), the previously input character and this time are input. A phrase combined with a letter will also contain emotions. That is, for example, when the character input last time is “happy” given the emotion ID “A” and the character input this time is “birthday party”, the character input last time is input this time. The combination of characters “Happy Birthday Party” also includes emotions.

  In this case, the control unit 4 newly assigns an emotion ID “A” as a predetermined character having emotion to the above-mentioned phrase “happy birthday party”. That is, the control unit 4 causes the update unit 10 in the information processing unit 5 to update the emotion character discrimination table 6 (ST23, ST24). That is, in the emotion character discrimination table 6, the phrase (character) “happy birthday party” is updated so that the emotion ID “A” corresponds.

Further, the control unit 4 causes the update unit 10 to update the prediction conversion candidate database 8 so as to correspond to the emotion character discrimination table 6. That is, for example, the characters “Net ☆”, “There was a thing!”, “ (^^) "is stored in a predetermined order.
As described above, after the emotion character discrimination table 6 and the predictive conversion candidate database 8 are updated, the emotion phrase determination flow ends.

  Thus, an emotion ID is newly assigned as appropriate not only for the previously input character but also for a clause composed of a combination with the character input this time. Therefore, when the user converts not only the character previously input in the character input unit 2a but also a character including emotion information based on a clause composed of a combination with the character input this time, the user inputs that the emotion information is included. Work becomes unnecessary. Therefore, the efficiency of converting the character input by the character input unit 2a into a character including appropriate emotion information is high, and convenience is improved.

Furthermore, since the emotion character discrimination table 6 and the predictive conversion candidate database 8 are constantly updated by the update unit 10, the efficiency and convenience of converting the characters input by the character input unit 2a into characters including appropriate emotion information. Is further improved.
In this way, the method for performing emotion phrase determination has been specifically described with reference to the flowchart of FIG.
Thereafter, the description returns to the flowchart of FIG.

  When the emotional phrase determination flow ends, the control unit 4 determines whether the phrase is a phrase including emotion and the emotion ID is given in the emotional phrase determination flow (ST10).

  When it is determined that the emotion ID has been assigned (Yes), the control unit 4 refers to the updated prediction conversion candidate database 8 and puts characters that are prediction conversion candidates for the phrase in a predetermined order. Therefore, it is preferentially shown in the conversion BOX 13 (ST6).

  When it is determined that the emotion ID is not assigned (No), the control unit 4 refers to the updated predictive conversion candidate database 8 and determines “Ne.” This is shown in the conversion BOX 13 in accordance with the order of (ST7).

  In addition, in the above flow, when the character input from the character input unit 2a (previous) or the character input this time is not input, the process of creating a sentence having characters including emotion information ends (ST11).

  Although the portable terminal 1 has been described as an example of the electronic apparatus of the present invention, the electronic apparatus is not limited to the portable terminal 1. In other words, the electronic device of the present invention can be applied to any electronic device that is desired to have a function of converting into characters including emotion information in sentence creation. For example, there are personal computers, PDAs (Personal Digital Assistants), and word processors.
