Description

  The present invention relates to a character input device with decoration mounted on an information processing device having a text processing capability, and in particular, for inputting message-type text such as an electronic mail in a terminal having a small display device such as a mobile phone. The present invention relates to a character input device with decoration that performs character decoration efficiently.

  As a decoration method in a conventional character input device, various methods have been proposed mainly for a word processor (Japanese processing device). (Type to specify the decoration method later) or specify the color, shape, attributes, etc. of the character before entering the character, and then enter the character to specify the decoration of the sentence to be input later (first In many cases, a method of selecting a decoration method is used.

  For example, if you want to decorate the “surprise” part of the sentence “I was very surprised today,” with red and large letters, Today, I was very surprised. ”Next, move the cursor to the beginning of“ Amazing ”, select the decoration method, specify the decoration range, apply the decoration, and then move the cursor again. Follow the procedure to move to the end of the sentence. On the other hand, when using the method of selecting the decoration method first, after the user inputs up to “Today, Super”, he selects red letters and capital letters from the menu, etc., then inputs “surprise”, and then the menu again. From this time, the red letter and capital letter attribute designation is cancelled, and "Sometimes I did it" is entered.

  Such decoration methods are becoming effective and common in devices with various input means such as dedicated word processor machines and personal computers. However, in either method, the user must revise the sentence in his / her head when inputting characters, and interrupt the operation and perform the operation every time decoration is performed. You have to switch.

  As means for solving such a problem, for example, there is a method as described in Patent Document 1. In this method, a character is input with an arbitrary character size, and a character size candidate other than the character size input as the input character conversion candidate is also output. Then, a candidate having a desired character size is selected from the output candidates, the selected character size and the character type of the conversion target character are learned in pairs, and the learned character type at the next arbitrary character size is learned. , The character size of the input character is automatically converted to the character size learned in pairs. For this reason, at the stage of kana-kanji conversion, the user has to decide on the decoration method.

  In addition to this, there is a method as disclosed in Patent Document 2, for example. In this method, when creating a user dictionary, attributes such as color, typeface, and underline / shading are registered in advance, so that characters, typefaces, underlined / shaded characters can be changed by simply confirming the conversion of the user dictionary. It is a method of input.

JP-A-7-160687 JP-A-8-292953

  By the way, in recent years, text-based communication by e-mail or the like has been actively carried out, and by changing the color of the text itself, changing the size, movement, etc. Means have been provided to convey the emotions of writers who do not communicate to readers.

  However, since the method disclosed in Patent Document 1 assumed a Japanese text input device (word processor) for monochrome display, the decoration method was limited to character widths such as half-width and double-width. When applied to e-mail decorations on telephone terminals, many combinations of colors, sizes, movements, etc. are displayed, so it is easy to lose the original kana-kanji conversion candidates on a mobile information terminal with a small screen. was there.

  In addition, the method disclosed in Patent Document 2 is effective in maintaining the uniformity of the entire document, since it is possible to decorate only the words registered in advance by the user. If it is considered to be applied to the creation of, the procedure reduction effect cannot be expected for words that are not pre-registered. Furthermore, the user needs to register the decoration method for each character in advance through a dedicated user interface.

  The present invention has been made to solve the above-described problem, and in a character input device that decorates a character string before finalizing the input character in the same phase as the kana-kanji conversion, the character string can be easily operated. An object of the present invention is to obtain a decorated character input device capable of embellishing a character.

  The decorated character input device according to the present invention includes a decorated character designating unit for designating conversion of a character string as a decorated character in a kana-kanji conversion process for an arbitrary character string, and a decorated character designating unit. When it is specified that the character string is converted as a decorated character in, a decorated character presenting means for presenting the character string of the decorated character as a conversion candidate, and a confirmation instruction for the presented decorated character conversion candidate If received, it comprises character confirmation means for confirming the conversion candidate as a kana-kanji conversion result of the character string.

  The character input device with decoration according to the present invention explicitly designates a character with decoration for an arbitrary character string in kana-kanji conversion processing, thereby presenting the character string of the character with decoration as a conversion candidate. Because of this, it is possible to decorate characters with simple operations.

The character determination unit 3 is realized by the processor 400 and the application framework 600, and is realized by the front-end processor 400 and the application framework 600. Also, the kana-kanji conversion engine 4 and the decoration method table 5 in FIG. 1 have configurations corresponding to the kana-kanji conversion engine 500 and the decoration method table 403 in FIG. 3, respectively.

FIG. 4 is an explanatory diagram illustrating a display example of the display unit 12 when the front-end processor 400 is operating.
As shown in FIG. 4A, the display unit 12 displays an edit box display unit 201, an input mode display unit 202, soft key display units 203, 204, and 205, a guidance display unit 206, and a candidate list display unit 207. Is done. The edit box display unit 201 is a part that displays an edit state held by the edit box 401 in the front end processor 400. Here, a character part without an underline part is a confirmed character string, and a character part with an underline part is an undetermined character string. The input mode display unit 202 is a display unit for indicating the input mode of the front-end processor 400, and FIG. 4 shows that kana-kanji conversion is effective. The soft key display units 203, 204, and 205 are examples of the soft key 14 in FIG. 2. In the illustrated example, when the function button 13 A is pressed, the function of the soft key display unit 203 is executed and the function is displayed. When the button B of the button 13 is pressed, the function of the soft key display unit 204 is executed. When the button C of the function button 13 is pressed, the function of the soft key display unit 205 is executed. The guidance display unit 206 is a guidance display unit that is displayed when a special function is assigned to the cursor key 15. As shown in FIG. 4B, the candidate list display unit 207 displays a candidate list held in the candidate box 402 in the front-end processor 400. In the illustrated example, kana-kanji conversion candidates are displayed. It shows the state being done.

Next, the operation of the first embodiment will be described.
FIG. 5 is an explanatory diagram showing screen operation transitions in the first embodiment.
6, 7 and 8 are explanatory diagrams showing the flow of control between the modules.
First, as shown in the screen A of FIG. 5, in the edit box display unit 201 is undetermined character string "Hello! (Newline) today is" a definite character string "fun it is," are held And In such a state, as in the guidance display unit 206, when the cursor key 15 is pressed downward, a conversion operation is performed.

When the user presses the downward direction of the cursor key 15, a screen transition from A → B occurs. At this time, each module in FIG. 3 operates as follows.
When the user presses the downward direction of the cursor key 15, a signal indicating that the downward direction key has been pressed is notified from the input means 100 to the front-end processor 400 via the application framework 600 (FIG. 6, step). ST101). Upon reception of this notification, the front-end processor 400 extracts the unconfirmed character string “Fun” from the character string held in the edit box 401 and passes it to the kana-kanji conversion engine 500 as a “read” character string. (Steps ST102 and ST103 in FIG. 6).

  The kana-kanji conversion engine 500 divides the “read” character string into phrase units and generates conversion candidates for each phrase (FIG. 6, step ST104), and the kana-kanji conversion candidate character string for the first phrase. The group is returned to the front-end processor 400 (FIG. 6, step ST105). Since the details of the operation inside the kana-kanji conversion engine 500 are known, a description thereof is omitted here.

The front-end processor 400 stores the kana-kanji conversion candidate character string group of the first phrase in the candidate box 402 (FIG. 6, step ST106).
FIG. 9 represents the character string list held in the candidate box 402 in this state in a logical table format.

Next, the front-end processor 400 issues a drawing instruction to the application framework 600 by designating the kana-kanji conversion candidate group of the first phrase as a drawing character string with size = medium, color = uniform black (FIG. 6). Step ST107). The application framework 600 creates a bitmap image of the candidate list from the data of the designated font size and the R / G / B value of the designated color (FIG. 6, step ST108), and displays it on the display means 200. Send drawing data.
As described above, the kana-kanji conversion candidates appear on the screen as shown in screen B in FIG.

  In the state of screen B, when the user presses the “confirm” key of the soft key display unit 205, the character string “fun” to which the selection cursor is placed in the candidate box 402 is confirmed, and the edit box 401 is displayed. Is replaced with the character string “fun” without decoration information, the candidate list is deleted, and screen drawing is performed (screen C).

Next, an operation procedure and an internal operation when the decoration operation is performed with the screen B as a base point will be described. In the present embodiment, an operation until the user confirms a character with a decoration of “fun” with “font size = large” and “color = yellow” will be described.
When the function button 13 corresponding to the “Deco” button on the soft key display unit 203 is pressed on the screen B, the front end processor 400 receives a notification that the key is pressed through the input unit 100 and the application framework 600. (FIG. 7, step ST201).

The front-end processor 400 extracts all the font colors corresponding to the font color table 601 in the application framework 600 for the character string “fun” selected in the candidate box 402 of the screen B, and says “fun”. Each font color is applied to the character string one by one (FIG. 7, step ST202), and a list of the color candidates is stored in the candidate box 402 (FIG. 7, step ST203). For 600, a drawing instruction is issued assuming that size = medium (FIG. 7, step ST204).
FIG. 10 represents the character string list held in the candidate box 402 in this state in a logical table format.

The application framework 600 creates a bitmap image of the candidate list from the data of the designated font size and the R / G / B value of the designated color (FIG. 7, step ST205), and displays it on the display means 200. Send drawing data.
With the above operation, the character string group “fun” expressed in each color is displayed on the candidate list display unit 207 as shown in the screen E in FIG.
In the present embodiment, for notation, the color is represented as a character such as “fun (red)” in FIG. 5, and each font color is black in the figure, but on the actual device screen. Then, it is assumed that the characters “fun” are displayed for each color.

Next, when the user presses the right direction of the cursor key 15 on the screen E in FIG. 5, a notification that the key is pressed is sent to the front end processor 400 through the input means 100 and the application framework 600 (FIG. 7). Step ST206). When the front end processor 400 detects that the right key is pressed in this state, the front end processor 400 increases the font size by one step from the current size for each display character string stored in the candidate box 402 (FIG. 7, step ST207). The data is stored again in the candidate box 402 (FIG. 7, step ST208), and a drawing instruction is given to the application framework 600 with size = medium (FIG. 7, step ST209).
FIG. 11 represents the character string list held in the candidate box 402 in this state in a logical table format.

The application framework 600 creates a bitmap image of the candidate list from the data of the designated font size and the R / G / B value of the designated color (FIG. 7, step ST210), and displays it on the display means 200. Send drawing data.
With the above operation, as shown in the screen F in FIG. 5, the character group “fun” using each color and the “large” font is displayed on the candidate list display unit 207.

  Next, if the user presses the down direction of the cursor key 15 three times and then presses the “confirm” key (center key) on the soft key display unit 205 (FIG. 7, step ST211), the selection is made in the candidate box 402. The character string “fun (yellow)” to which the cursor is placed is confirmed, and the character string “fun” held in the edit box 401 is replaced with a character string “fun” in a large font and yellow display ( FIG. 7, step ST212). Next, the front-end processor 400 deletes the contents of the candidate box 402 (FIG. 7, step ST213), and learns the weight value (FIG. 7, step ST214). Then, a screen drawing request is made (FIG. 7, step ST215), the application framework 600 constructs a bitmap image for drawing (FIG. 7, step ST216), sends drawing data to the display means 200, The screen is updated (screen G in FIG. 5). The learning in step ST214 will be described later.

  On the other hand, when the “return” key is pressed from the state of the screen F in FIG. 5, the front-end processor 400 once discards the contents of the candidate list in the candidate box 402 and then instructs the kana-kanji conversion engine 500 to “ It is possible to pass the “read” character string and make a reconversion request to return the screen state to the state of screen B.

On the other hand, in the state of screen B in FIG. 5, it is possible to apply a suitable decoration method to the candidates in the candidate box 402 as the designation of a specific character conversion method with decoration, which is a soft key display unit 204. The instruction is given by pressing the function button 13 corresponding to the “recommend” button (right key).
In the following, an operation until the user determines the characters “fun” of “font size = large” and “color = yellow” from the decoration method candidates determined to be suitable by the terminal will be described.

When the function button 13 corresponding to the “Recommend” button on the soft key display unit 204 is pressed on the screen B, the front end processor 400 receives a notification that the key is pressed through the input unit 100 and the application framework 600. (FIG. 8, step ST301).
When the front end processor 400 receives the key press notification, the front end processor 400 searches the decoration method table 403 for the character string “fun” selected in the candidate box 402 of the screen B, and the weight value of each decoration method element. Is acquired (FIG. 8, step ST302).
FIG. 12 represents the internal data of the decoration method table 403 in a table format.

Next, the front-end processor 400 calculates a weight for each combination method that can be decorated simultaneously from the acquired values (FIG. 8, step ST303). In the present embodiment, it is assumed that any “size” and any “color” can be combined, so 3 × 12 = 36 combinations of decoration methods are possible. The weight values of these 36 combination decoration methods are calculated as the product of the weights of the combination elements.
FIG. 13 is an explanatory diagram expressing the combination methods and the weight values of the respective combination methods in a table format.

  Next, the front-end processor 400 extracts elements having a value equal to or greater than a predetermined threshold from the weighting values for each combination method, and rearranges them in descending order of weighting values (FIG. 8, step ST304). In this embodiment, it is assumed that the threshold value = 7, and FIG. 14 shows an example in which the element group extracted and rearranged by the front-end processor 400 is expressed in a table format.

Next, the front-end processor 400 stores the extracted elements in the candidate box 402 (FIG. 8, step ST305), and issues a drawing instruction to the application framework 600 (FIG. 8, step ST306).
FIG. 15 represents the character string list held in the candidate box 402 in this state in a logical table format.

The application framework 600 creates a bitmap image of the candidate list from the data of the designated font size and the R / G / B value of the designated color (FIG. 8, step ST307), and displays it on the display means 200. Send drawing data.
As a result of the above operation, a character string group of “fun” expressed in each color and size is displayed on the candidate list display unit 207 (see FIG. 4) as shown in the screen D in FIG.

  Here, when the user presses down the cursor key 15 twice and then presses the “OK” key of the center key of the soft key display unit 205 (FIG. 8, step ST308), the selection cursor in the candidate box 402 is selected. The character string “fun (yellow)” of the large font size to which is applied is confirmed, and the character string “fun” held in the edit box 401 is the character string “fun” in the large font and yellow display. (Step ST309 in FIG. 8).

  Next, the front-end processor 400 deletes the contents of the candidate box 402 (FIG. 8, step ST310), learns the weight value (FIG. 8, step ST311), and draws the screen on the application framework 600. A request is made (FIG. 8, step ST312). The application framework 600 constructs a bitmap image for drawing (FIG. 8, step ST313), and drawing is executed. The learning operation in step ST311 will be described later.

  In the state of screen D in FIG. 5, when the user presses the “return” key, the front-end processor 400 discards the contents of the candidate box 402 and sends the “read” character to the kana-kanji conversion engine 500. It is possible to return the screen state to the state of the screen B by passing the column and requesting reconversion.

In this embodiment, the combinations that can be decorated at the same time are composed of two types of “size” and “color”. However, “motion” such as blinking, telop, and swing of characters, and “shaded” of characters. It is also possible to increase the number of combinations such as “”. Also in this case, the weights of the combined decoration methods can be calculated by integrating the weights of the decoration methods themselves.
Each weight may be set in advance, but may be set by the user. In this case, it is preferable to provide means for returning all set values to the initial state.

Next, the learning operation in FIG. 7, step ST214 and FIG. 8, step ST311 described above will be described.
The user presses the “Confirm” button on the soft key display unit 203 from the state of the screen F or the screen D in FIG. 5 to confirm the kana-kanji conversion and decoration method and reflect the edit box (FIG. 7, step ST212 and FIG. 8). Before or after step ST309), the front-end processor 400 performs the following operation. The example shown in FIGS. 7 and 8 shows a case where the editing is performed after the edit box 401 is reflected.
FIG. 16 is a diagram illustrating a learning process flow of the front-end processor.
When the front-end processor 400 obtains the event of pressing the confirm button (FIG. 16, step ST401), the front-end processor 400 obtains the character string confirmed from the candidate box 402, and the keyword in the decoration method table 403, that is, the first column in FIG. The determined character string of the eye is searched (FIG. 16, step ST402). Next, it is determined whether or not a confirmed character string exists (FIG. 16, step ST403), and the process branches.

First, when the character string confirmed this time is not found in the current decoration method table 403, a new line is added to the decoration method table 403 to use the confirmed character string as a key (FIG. 16, step ST404), and then The weight value of each decoration method is registered. As the weight of each decoration method, 0 is entered if the decoration method is not used for the fixed character string, and as follows if the character string is used for the fixed character string.
A = the number of types of combination elements that can be simultaneously decorated. In the present embodiment, “size” and “color” are two.
B = threshold used in FIG. 8, step ST304. 7 in this embodiment.
f (a, b) = a-th root of b INT (a) = integer value of a (rounded down)
, A value of weighting value = INT (f (A, B)) + 1 is registered. In this embodiment, since A = 2 and B = 7, the weight to be entered is 3.
This is because the candidate display (FIG. 5, screen D) by the “recommend” key is immediately performed at the time of the next conversion work. However, when the display is made after several learning results, simply You may register 1 only.

On the other hand, when the character string determined this time is found in the decoration method table 403, the following operation is performed (FIG. 16, step ST406).
Z = maximum value of each weight value in the table. Thirty in the present embodiment.
C = Current weighting value of a particular cell in the discovered table.
Then, a value of weighting value = INT ((Z−C) / 2) is added to the current value. In this embodiment, since Z = 30, a value of 18 is entered when C = 6, a value of 27 is entered when C = 24, and a value does not vary when C = 30.

Although not limited to the above-described method, it is possible to avoid a situation in which the value of only a specific cell protrudes and becomes large by using a method in which the increase value is gradually attenuated after the weighting value becomes high to some extent. If the calculation capability of the device in which this method is installed is low and other operability is affected, 1 is added to C if Z> C, and no change is made if Z = C. good.
In addition, these are approaches that gradually fix the learning results, but a mechanism is adopted in which new words are given priority by performing processing such as periodically deleting words that are not referenced for a certain period of time. It is desirable to have it. It is further desirable to provide a means for the user to return all weight values to their initial values.

  As described above, since the character decoration method is configured to have an operation means for presenting a suitable decoration method to the user in the middle of the kana-kanji conversion, the user can send an e-mail message containing the decorated character. When creating the text, it is possible to input without interrupting the thought of creating the text and without deteriorating the operability of selecting a normal kana-kanji conversion candidate, and the operability at the time of creating the text with decoration can be improved.

  As described above, according to the first embodiment, the decorated character designating means for designating that the character string is converted as the decorated character in the kana-kanji conversion processing of the arbitrary character string, and the decorated character When the designated character is designated by the designating means, the decorated character presenting means for presenting the character string of the decorated character as a conversion candidate, and when the confirmation instruction is received for the presented decorated character conversion candidate Since the character confirmation means for confirming the conversion candidate as the kana-kanji conversion result of the character string is provided, the character can be decorated with a simple operation.

  Further, according to the first embodiment, the decorated character presentation means has the decoration method selection means for selecting the decoration method of the presented character string, and one of the decoration methods is selected by the decoration method selection means. In this case, the user can obtain a decoration result by a desired decoration method because the character string is made up of characters with decoration of the decoration method.

  Further, according to the first embodiment, the decoration method table having the character string and the decoration method weight value information is provided, and the decoration character presentation unit converts the character string when the specific decoration character conversion method is designated. Since the character string of the decoration method based on the weight value in the decoration method table is preferentially presented as a candidate, the user can obtain a decoration result based on the decoration method determined to be suitable in advance.

  In addition, according to the first embodiment, the character determination unit increases the weight value of the character string in the decoration method table when the determination operation is performed on the character string of the decorated character presented as the conversion candidate. The decoration result can be reflected in the decoration method table, whereby a decorated character input device that is easier for the user to use can be obtained.

Embodiment 2. FIG.
In the second embodiment, the user can arbitrarily correct the decoration, and the configuration on the drawing is the same as that of the first embodiment. Therefore, the second embodiment will be described with reference to FIGS. .
The decorated character designating means 1 according to the second embodiment is configured to accept an input relating to correction of decoration based on, for example, the type of emotion and the strength of emotion. The decorated character presentation unit 2 is configured to increase or decrease the weighting value in the decoration method table 5 based on the content of the correction input designated by the decorated character designation unit 1. Other configurations are the same as those in the first embodiment.

FIG. 17 is an explanatory diagram showing a screen displayed immediately before the mail application 300 starts the front-end processor 400 in the second embodiment.
The mail application 300 displays a screen as shown in the drawing on the display unit 12 and prompts the user to input a parameter to be reflected when creating a message.
In FIG. 17, a hue selection button 211 is a button prepared for temporarily increasing or decreasing the weighting value in the color decoration of the decoration method table by designating the type of emotion at that time by the user. This shows a state in which the third “sad” is selected among the item choices. The highlight selection button 212 is a button prepared for temporarily increasing / decreasing the weighting value regarding the font size of the decoration method table 403 by designating the strength of emotion at that time, and currently has four items. This shows a state in which the second “ordinary” is selected. The explanation window 213 is a window for displaying a sentence explaining what the combination effect of the selected parameters will be. The edit button 214 is a right soft key for starting editing with the selected parameter, and can be operated by pressing the corresponding function button 13.
With such a configuration, correction input related to decoration can be performed.

Next, the operation when the user selects “hue selection” and “emphasis selection” on the screen shown in FIG. 17 and starts editing the mail will be described. The operation from when the user inputs a character until the kana-kanji conversion candidate is displayed is the same as that in the first embodiment, and thus the description thereof is omitted.
When the function button 13 corresponding to the “recommend” button (right key) of the soft key display unit 204 is pressed on the screen B in FIG. 5, a notification that the key is pressed through the input unit 100 and the application framework 600. Reaches the front-end processor 400. When the front end processor 400 receives the key press notification, the front end processor 400 searches the decoration method table 403 for the character string “fun” selected in the decoration method table 403 on the screen B, and displays each decoration method for the character string. Get element weights.

Next, the front end processor 400 corrects the value for the weight of each decoration method element using a color correction table and a size correction table separately prepared in advance.
FIG. 18 and FIG. 19 are explanatory diagrams expressing the color correction table and the size correction table in a tabular format, respectively, and the first column corresponds to words that can be selected by the user by hue selection and enhancement selection, respectively. .
For example, when the user selects “hue selection” = “sad” on the screen shown in FIG. 17, the values described in the corresponding row in the table, that is, red = −3, yellow = 0, blue = + 3. Is adopted as a correction value for decoration related to color. When the user selects “highlight selection” = “normal” on the screen shown in FIG. 17, the values described in the corresponding row in the table, that is, small = 0, medium = + 2, large = 0,... Is adopted as a correction value for the font size.

The front-end processor 400 adds the correction value to the weighting value of each decoration method element and calculates the weighted product of the combination elements.
FIG. 20 is an explanatory diagram in which the combination methods and the corrected weight values of each combination method are expressed in a table format.
In FIG. 20, P (a) means a function that is a if a is a positive number and 0 if a is a negative number.

Next, the front-end processor 400 extracts elements having a value equal to or greater than a predetermined threshold from the weighting results for each combination method, and rearranges them in descending order of weighting values.
FIG. 21 is an explanatory diagram showing the results when extraction is performed with threshold = 7, as in the first embodiment.
In contrast to the state shown in FIG. 15 in the first embodiment without correction, when the user selects parameters such as “sad” and “normal”, the decoration of the red element and the decoration of the large font size disappear, and instead the blue color You can see that the decoration of the element has appeared.

  In this way, the weighting values in the decoration method table 403 are corrected according to the parameters specified in advance by the user when starting the mail editing, so that the parameters specified by the user first are adjusted. Thus, the presentation content of the decoration combination element can be changed.

  As described above, according to the character input device with decoration according to the second embodiment, the character specification means with decoration accepts correction input related to decoration, and the character presentation means with decoration is the correction specified by the character specification means with decoration. Since the weighting value is increased or decreased based on the contents of the input, in addition to the effects of the first embodiment, a decoration result desired by the user can be obtained.

In addition to the mail application 300, various applications such as a schedule application and a telephone directory application are installed in the mobile phone device that is assumed to be equipped with the decorative character input device of the present invention. It is assumed that 400 is activated. Generally, since only the mail application 300 requires a decoration character string, the necessity of decoration can be specified as a startup parameter of the front-end processor 400, and the decoration function can be specified only in the mail application 300 or an application that requires decoration. It is desirable to make
However, the present invention is not limited to such a cellular phone device, and can be applied to various devices as long as they are devices for inputting decorative characters.

  In addition, the decoration method can be applied not only to fonts and sizes, but also to movements and shading, as well as any decoration method.
