Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to interactive information for executing a function by designating a button displayed on a screen, such as displaying and selecting a candidate by character recognition of an input stroke using a tablet and a pen. It relates to a processing device.

[0002]

2. Description of the Related Art In recent years, in the field of portable information devices and terminal devices, a display integrated tablet device which has both a display portion for inputting various data items such as kana, alphanumeric characters and symbols, and an input portion. Are being developed and used. In such a device, an input method is adopted in which an operator inputs desired characters and the like by touching a keyboard (hereinafter, referred to as “soft keyboard”) displayed on a screen of the device with a pen. In addition to the soft keyboard, a method of inputting a combination of character recognition for recognizing an input stroke and kana-kanji conversion for converting an input kana into a kanji-kana combination string is used.

[0003] Handwritten character recognition, kana-kanji conversion,
A number of virtual keyboards, such as onon input, user words, "50-sound board" for Japanese kana, "typewriter board" for alphanumeric characters, and "number input board" for numbers and arithmetic symbols. There are also products that can be used by switching between them. With these functions, Japanese characters of various character types can be input. Also, list symbols and commonly used words,
A word selection input method of inputting a corresponding character string by a user's selection operation has also been realized together with the above-described method using handwritten character recognition.

In particular, in the case of handwritten character recognition, erroneous recognition often occurs. Therefore, a method of inputting while sequentially confirming recognized character candidates has been proposed.

FIG. 4 is a schematic diagram showing an example of a screen layout in a conventional information processing apparatus for inputting characters by handwritten character recognition. When character strokes are sequentially input in the box A in the figure, recognition candidates of the recognition result are displayed in the box B.
In the box C, the first candidates of the sequentially input character recognition candidates are sequentially displayed as temporary selection candidate characters, and editing such as deletion and candidate change is performed by a pen operation. The frame of D is a display area for the final confirmed character.

On the other hand, when recognizing a kanji character, a user who has not completely memorized the stroke of the character inputs the reading into a dedicated handwriting input frame and causes the character to be recognized. There is a system equipped with a Kana-Kanji conversion function that converts to a corresponding Kana-Kana mixed line by touching (for example, Liquid Crystal Pencom Z manufactured by Sharp Corporation)
aurus PI5000).

Also, in this system, when inputting the time of the schedule, a bar is displayed between the point where the pen is touched and the point where the pen is touched, and the schedule start time and the end time can be input simultaneously.

Further, in this system, if there is a character that cannot be recognized, a clear reject message "character cannot be recognized" is issued and the input is ignored.

[0009] Also, when editing the input text,
After dragging the text on the screen, "half-width / full-width conversion" can be performed by a "delete" button at a predetermined position, a "convert" button, or a pull-down menu.

[0010] In addition, by dragging a number on the input text and performing a "postal code conversion" instruction in a pull-down menu, a corresponding place name can be input.

In order to input the number of strokes that are difficult to input or difficult to read even in character recognition or kana-kanji conversion, there is a system that searches for a desired kanji by designating the number of strokes or radicals of the character. (For example, Panaward U1PRO N10 manufactured by Matsushita Electric Industrial Co., Ltd.) In this system, a list of radicals is displayed according to an instruction, and when one of 267 radicals is selected, a list of kanji having the corresponding radical is displayed. indicate. When a number of strokes from 1 to 30 is input, a list of corresponding kanji is displayed.

Further, there is a system in which, when displaying a sentence, a predetermined space between lines is left between lines to enhance the striatedness of the text so as to make it easier to read (for example, Microsoft Word V manufactured by Microsoft Corporation).
er. 6.0).

[0013]

However, in the character input method based on handwritten character recognition, it is necessary to sequentially display and confirm recognition candidates as shown in FIG. 4, so that a dedicated character recognition candidate display area is secured. Had to be put. In particular, when used as a portable information terminal, a dedicated display area is originally required for a small display screen area, and there is a problem that "the screen is not effectively used". For this reason, the character input frame that should originally be larger is limited to a small size, which is not limited to a display problem, and has an adverse effect on input such as “input operability is poor”. Forcibly increasing the size would increase the size of the device itself, causing the problem of "losing portability". In addition, although it is possible to switch the screen to display one by one, it is possible to cause flickering of the screen, impair cognitive operability, and easily cause fatigue.

In a conventional system, as shown in FIG. 4, since the screen is small, the handwriting input frame and the recognition candidate display frame are often close to each other. Sometimes, the pen accidentally touched the handwriting input frame while doing it. The conventional system that activates character recognition processing by giving priority to drawing in the handwriting input box and pen input interprets the erroneous operation input as character handwriting input, obtains the recognition result, and displays it as a candidate in the B or C box. I do. Then, the user has to delete the erroneously input character, display the initial candidates, and then select a desired candidate, which takes time and effort to recover the erroneous operation.

Further, the conventional information processing apparatus has the following problems in addition to the above-mentioned problems.

The same button may be commonly used in a plurality of modes. However, conventionally, the button is displayed at one fixed position for each function, so unless the pen tip is moved a long distance and the button is touched. did not become. That is, there is a problem that "the pen movement distance is long when the same instruction is made in a plurality of modes".

When converting the result of character recognition to Kana-Kanji conversion, the position of the pen differs between the state where the pen is in the vicinity of the recognition frame and the state where the input kana has been corrected. there were.

In addition, when rejection with no corresponding candidate occurs as a result of character recognition, the result is ignored, so that there is a problem that it is difficult to find a missing part after input. Another problem is that it is difficult to distinguish whether or not the reject character has been input by the recognition unit. In addition, there is one that enables the following processing on condition that the rejected character is eliminated, which impairs the flexibility of editing. Further, there is a problem that it takes time to input a reject character.

Further, when inputting the time, there is another problem that it is difficult to understand the exact time by inputting the time in a graph format. In addition, if the input position is not correct, the time input may not be correctly performed.

Further, when the same function is repeatedly applied to a character string, it is necessary to give a function instruction each time the character string is selected, which is difficult to use. It takes time and effort to give individual function instructions for a plurality of correction functions. In particular, this problem occurs in the case of correcting an erroneous recognition result, or performing an allomorph conversion in which difficult characters are input as slang characters with a small number of strokes and then converted into formal characters.

Further, there is a problem that when a kana-kanji conversion instruction is given without noticing a hiragana character recognition error, it takes time and effort to obtain a correct conversion result.

Another problem is that the operation for inputting the place name from the postal code is troublesome. In general, it is difficult to read kanji with many strokes and it is difficult to memorize the stroke order accurately.However, when inputting such kanji, a search method for specifying candidates by specifying the number of strokes of kanji is known. However, such kanji are also difficult to accurately grasp the number of strokes.
There is a problem that "the number of strokes cannot be specified accurately when inputting difficult characters".

Also, it is difficult to display sentences easily on a limited screen size. Further, when a plurality of character types are switched using a software keyboard, when a designated character including an unconvertible character type is composed of a plurality of character types, a character type conversion order useless character type switching operation may be required. For example, in a system called shift JIS code, half-width hiragana characters are not defined,
If "character width conversion" is instructed for "hiragana + half-width numeral", the first instruction does not respond at all in the case of priority for half-width.

Next, the operation and function of the character input device will be described in detail with reference to flowcharts with reference to FIGS. 1 to 6 described above. In the following description, it is assumed that various system variables are initialized in advance. Although not described in detail here, some initial settings can be selected by a user in a predetermined initial menu. For example, the MSB of the prohibited state storage area 609 is set to 0 or 1 at the time of initialization.

FIG. 7 is a flowchart showing a process for changing the system state when the user touches the application selection button 209 shown in FIG. In the input waiting state, the user selects a predetermined application selection button 20 in order to instruct an application selection.
When 9 is touched, a designated application screen corresponding to each button is activated. Therefore, after setting the corresponding application identification information (application ID), the system enters an input waiting state. Here, the typical “Japanese editing”, “English editing”, and “address book / business card” applications are shown, but the same applies to other applications. FIG. 2 shows a display example when "Japanese text editing" is selected as the application.

FIG. 8 is a flowchart showing a process when the character input device performs character input using character recognition when a Japanese text editing application is selected. When the user turns on the power, an initial screen in the form of a frame shown in FIG. 2A is displayed, various system control information is initialized, and the system waits for input.

In this state, when the user first tries to enter the first stroke of the kanji desired to be input into the handwriting input frame 206 with the pen 109, the first point is input. The prohibition information stored in the prohibition state storage area 609 is determined to be true or false. If the LSB is 1 and the prohibition state is set, the input to the handwriting input frame after the input is ignored.

Otherwise, the stroke data detected by the tablet 108 is extracted into the first stroke row of the handwriting information temporary storage area 503 in the main memory 103 via the input / output control unit 107 at a predetermined sampling rate. It is stored as dimensional point sequence data. At the same time, LC
The handwriting is displayed at a position corresponding to the input position of the D panel 106. At this time, referring to the input state storage area 614, if the recognition candidate is in the display state, the recognition candidate frame 205 is deleted, and the saved screen is returned to the original state.

Next, which of the plurality of handwriting input frames 206 is the frame is determined with reference to the screen layout storage unit 312, and it is determined whether or not the frame is the same as the current input frame number 606. If the frame has not changed, the system returns to the waiting state, and the stroke input for the second and subsequent strokes is continuously performed.

When the handwriting input frame changes, first, a second conversion button is displayed outside the new frame. This button performs the same function as the “conversion button” in 208, and can perform a conversion instruction with less movement of the pen during input of the current handwriting.

Similarly, a "recognition button" is displayed outside the frame. When this button is touched, the system regards that the character handwriting currently input to the frame is completed.

Next, the system regards that the handwriting information for one character has been completed in the frame, and starts the character recognition operation. That is, the feature is extracted from the input stroke sequence, and is compared with the standard pattern stored in the character recognition standard pattern dictionary storage unit 307. As a result, a collation score is given to each candidate, and characters that exceed a predetermined lower limit value are stored in the recognition candidate temporary storage area 504 as character recognition results in order from the character with the highest score as the character recognition result. If no candidate has a score equal to or greater than the lower limit, a reject signal is output.

If there is a reject signal, the system
A special code for which no recognition pattern is registered in the dictionary storage unit 307 as an initial recognition candidate in the recognition candidate temporary storage area 504 and which cannot be input to 203 even using other input means is set as a reject character. For example,

[0070]

[Outside 1]

The characters are as follows. In the system according to the present embodiment, the input for special characters performed by designating a delimiter code or the like is not supported by the input pad 202, so that (outside 1) cannot be input to the input box 203.

Thereafter, the system displays the first candidate character string in the input character information temporary storage section 501 on the input box 203, and returns to the input waiting state again.

FIG. 10 is a flowchart showing a process when the user selects a candidate other than the first candidate in a state where the recognition candidate character is displayed in the recognition candidate frame 205 shown in FIG. The user who finds an undesired candidate among the candidates displayed in the input frame 203, determines the position of the corresponding character from among the plurality of recognition candidate characters displayed in the recognition candidate frame 205 or the upper and lower positions thereof. Pen 1 near the position
Touch with 09. The system determines which character in the input character information temporary storage unit 501 is the character specified from the touched position, and determines the recognition candidate temporary storage area 504.
It is determined whether the designated character is a character recognition input character or a kana-kanji conversion input character by determining which of the phrase number storage areas 505 has valid information.

If the input character is a character recognition input character, the system thereafter saves the area for seven characters displayed at the upper left of the handwriting input frame 206 as an overlapping area on the operation control information temporary storage area 304. If the most significant bit (MSB) of the contents of the prohibited state storage area 609 is 0, the least significant bit (LSB) is unconditionally set to 0 in the allowable state,
Is 1, the LSB is set to 1 indicating a prohibited state.
Then, candidates below the next rank of the candidate specified in the current recognition candidate number area 604 are displayed on the recognition candidate frame 205, the recognition candidate display state is set in the input state storage area 614, and the process returns to the input waiting state.

If the character is a conversion character, the notation information of the next rank of the candidate specified in the current conversion candidate number area 605 is displayed on the input box 203 as the first candidate, and the input wait state is entered. Return.

FIG. 11 is a flowchart for explaining the operation when a candidate on the recognition candidate frame 205 is designated by pen touch.

When the inside of the recognition candidate frame 205 is touched, the selected candidate is identified based on the layout information, and a candidate number is set in 604. Next, it is determined whether or not the kana-kanji conversion is being performed based on whether the content of 505 is valid. If the conversion is being performed, the recognition first candidate displayed in the reading frame is updated according to 604. Then, the control is shifted to FIG. 13B, and after the re-conversion, the conversion candidates are displayed and the apparatus enters the input waiting state. If conversion is not being performed, the first recognition candidate displayed in the input frame 203 is updated according to 604, and input is awaited.

FIG. 12 is a flowchart for explaining the processing when a Chinese character is input by designating a radical. An example of the corresponding screen will be described with reference to FIG.
First, if the single button is tapped when the input frame 203 is empty, a radical designation frame is displayed on the left of the character frame region as shown in FIG. In this state, tapping the areas A, B, and C displays the radicals corresponding to "Changing", "Unknown", and "Creating" as shown in FIG. 29B, and waits for input. When one of the radicals is selected here, a list of kanji corresponding to the radical is displayed. In FIG. 29, a list of the corresponding kanji is displayed in (c) in accordance with the selection of "sanzuihen" in (b). Here, a desired kanji is further searched and selected, and this is input to the character frame 203. FIG.
In FIG. 9C, “dirty” is selected.

FIG. 13 is a flowchart showing the reprocessing for the characters displayed in the input frame 203 shown in FIG. In the input waiting state, first, it is assumed that a character has been input in the input box 203 by any method.
When the “confirm” instruction button in “04” is touched, it is regarded that the display candidate in input frame 203 has been selected, and 604, 6
Performs the determination process of transferring the candidate text No. 05 to the application, and sets “half-width direction” as the character width change priority information.
Is set to 613, and the process returns to the input waiting state. Control frame 204
When the “conversion” button in the box or the “second conversion button” outside the frame of 206 being touched is touched and the kana-kanji conversion is instructed, the value in the phrase number storage area 505 of the input character information temporary storage unit 501 is referred to. Then, it is determined whether or not the kana-kanji conversion has already been performed. If it is in the conversion state, the next candidate is displayed with reference to the current conversion candidate number area 605 for the phrase specified by the current attention phrase number 603, and the process returns to the input waiting state.

If it is not in the conversion state, reference is made to the recognition candidate temporary storage area 504 and the current recognition candidate number area 604, and then the kana-kanji conversion is performed to set the phrase number storage area 505 and other conversion information. , 505 in the input box 203 and the recognition candidate temporary storage area 50.
The first candidate of No. 4, ie, the input reading, is superimposed and displayed in the reading frame immediately below the input frame 203, and the process returns to the input waiting state. This situation is as shown in FIG. Note that the internal processing of the kana-kanji conversion is not the purpose of the present invention, but may be an existing one, and therefore the description is omitted.

When the "recognition button" outside the handwriting input frame 206 is touched, it is considered that the current handwriting input has been completed, and the recognition processing shown in FIG. 8A and thereafter is executed.

When the correction button is touched, the identification information indicating that the correction function has been selected is recorded in the function identification information storage area 610, and the correction button is inverted to wait for input. The same applies to a variant button.

When the part button is touched, a part kanji dictionary is searched using each of the character strings 504 displayed on the input frame 203 as a key. The format of this dictionary is shown in FIG.
As shown in (1), kanji including the kanji as a part is stored in correspondence with the list of kanji to be recognized. The example of FIG. 27 shows a state where the part button is touched in a state where the kanji characters “tree”, “eye”, and “ten” are recognized.
As shown in FIG. 9, when the intersection of each part kanji and the corresponding kanji set is calculated, the kanji “plant” is determined.
As shown in (b), a kanji “plant” is displayed in the input frame 203.

When the "Single Kanji" button is touched in the state where a number is input in the input box 203, the input number is interpreted as the number of strokes as shown in FIG. I do. In the above case, a range of only one upper and lower sides of the designated number of images is designated as the number of images to be displayed. Otherwise, the designated number of strokes is designated as the number of displayed strokes. Next, the number of displayed images is displayed in the input pad column, and the system enters an input waiting state.

The process of selecting a displayed item by touching it is the same as the other processes, and a description thereof will be omitted.

When the "half / full" button is touched as a character width change instruction and the character width of the character string in input box 203 is changed accordingly, first, reference is made to character width change priority information 613. I do. If half-width is prioritized, it is determined whether the character string in the input box 203 can be reduced to half-width, half-width is performed if possible, and full-width is performed otherwise. If full-width is prioritized, it is next determined whether the character string in the input box 203 can be full-width, and if possible, full-width is executed; if not, half-width is performed. The determination that half-width and full-width can be made is determined as an attribute for the character code. Since the present system uses the shift JIS code, the following judgment is made.

(A) Full-width hiragana → half-width hiragana impossible (B) Full-width katakana → half-width katakana possible (C) Full-width kanji → half-width kanji impossible (D) Full-width alphanumeric → half-width alphanumeric possible (E) Half-width katakana → full-width Katakana Possible (F) Half-width alphanumeric → Full-width alphanumeric Possible Explaining with the screen of FIG. 28, if the “half / full” button is touched as a character width change instruction in the input state of FIG. Since there is “half-width”, which is the priority direction set at the time of implicit time, it is determined whether half-width is possible. Since a full-width numeral “12” is included, half-width is performed as shown in (b). If the "half / full" button is touched further in this state, it is determined whether "full-width" is possible because the priority direction is reversed, and the half-width "12" and "sui" can be full-width. , (C) is performed.

On the other hand, in the case of the input as shown in (d), it is impossible to determine whether half-width can be achieved by assuming the implicit "half-width". In this case, full-width is performed in this case. As a result, the output is as shown in FIG. If the “half / all” button is further touched in this state, the priority direction does not change, so that it is determined whether “half-width” is possible, and the conversion as shown in (d) is performed if possible.

In any case, possible conversion is performed, and conversion can be alternately performed by touching the same button.

FIG. 15 is a flowchart showing a processing procedure when a correction process is performed on the text text input to the text editing frame 201. When the system detects that the position in the text editing frame 201 has been touched in a state where the function has already been selected, the system refers to the text layout information stored in the operation control information temporary storage area 304, and The number of the character in the text corresponding to the specified position is calculated, and the calculated value is stored in the start position storage area 611 as a start point position, and input is waited.

Similarly, when pen-off is detected, the text character position corresponding to the designated position is stored in the end position storage area 612. Then, first, it is determined whether or not a reject character exists in the range between the start point and the end point. If so, the correction processing in FIG. 16 is first executed. Next, referring to the function identification information stored in the function identification information storage area 610, the corresponding function is stored in the start position storage area 61.
1 and the end text storage area 612. For example, if "variant" is designated, variant character processing is started. If it is "underline", the corresponding part is underlined.

FIG. 16 is an explanatory diagram for explaining an operation in the case where a character rejected by character recognition is corrected and input in the information processing apparatus according to the present invention. FIG.
9A is a diagram for explaining a dictionary storage format for correction, which is stored in the correction dictionary storage unit 313. As shown in the figure, an index of one kanji character is used, and a position where the kanji is included in a term is used as a secondary index. Then, "2
A search for "a term that includes" kai "in the characters" can be easily realized. FIG. 16B is a flowchart showing the procedure of the correction process. First, in the process of “next kanji extraction”, unprocessed kanji is extracted. For example,

[0093]

[Outside 2]

When the designation is made, first, the first character "luck" is extracted. Next, the correction dictionary storage unit 313 is accessed based on the kanji and its location to search for a term. For example, "operation, transportation, athletic meet" or the like is searched for as the first character "luck". Next, if there is an existing term, the intersection with the newly searched term is calculated. At this point, if unprocessed kanji remains in the text to be processed, the process returns to the first process. For example, in the case of (2), the second character is a reject character and processing is excluded, and the third character "" is processed. Then, "concerts, athletic meet, photo session, operation meeting" and the like are searched, and if the intersection with the existing "operation, transportation, athletic meet" is taken, "athletic meet, operation meeting" remains. FIG. 22 shows a screen display example in that case.

FIG. 18 (a) is an explanatory diagram for explaining the operation in the case where a simplified font character input by handwriting is corrected to a formal variant character in the information processing apparatus according to the present invention. FIG. 18A illustrates a dictionary storage format for correction, which is stored in the fixed dictionary storage area 303. As shown in the figure, the configuration is such that the corresponding allomorph can be searched using the index of one kanji character. FIG. 18 (b)
Is a flow chart showing the procedure of this allomorph correction processing. First, in the process of “next kanji extraction”, unprocessed kanji is extracted. For example, when "Saito" is specified, the first character "Sai" is extracted. Next, the dictionary shown in FIG. 18A is accessed from the kanji to search for allograph kanji. For example, for the Chinese character “Sai”, “Sai, Sai”
Is searched. If there is such an allomorph, it is displayed on the screen as shown in FIG. 24. Therefore, if the user selects a desired kanji, the character of "sai" of "saito" specified in the sentence is rewritten. If there is no allograph, the process proceeds to the next character.

FIG. 23 is a diagram for explaining the use status of the time input bar for inputting the time. As shown in the example, the “contact application” is activated, and an item input screen appears. Here, when the user finishes inputting the date and touches the pen at the end of the next time field, the cursor is displayed at the corresponding position, and the time bar is displayed in the input pad area at the bottom of the screen.

FIG. 17 shows an operation flow of the input bar for inputting the time thereafter. When the pen is touched on the time bar, first, the touch position is detected. The time value is converted to a time value in 15-minute intervals in correspondence with the y coordinate of the touch position, and a value indicating a two-digit minute is obtained by sandwiching a two-digit time and a colon. Next, this time value is displayed as a decimal Arabic numeral at the lower left position of the time bar as shown in FIG. When the pen is turned off, the hour data and minute data displayed at that time are stored in the hour area and minute area of the column where the cursor is located, respectively, as shown in FIG. The result is the same whether the cursor is in the minute area or the hour area as shown in FIG.

FIG. 25 shows a procedure for correcting the kana-kanji conversion and then correcting the kana-kanji when the kana-kanji recognition is incorrect. If you tap the "Convert" button with the intention of recognizing and inputting "Hikai" of Hiragana in (a),
The reading is converted according to the processing of FIG. 13, and as shown in (b), the conversion result is displayed in the input frame 203 and the reading is displayed in the reading frame immediately below the input frame. In the input, "he" is katakana "he"
If it is recognized, the conversion result is not “closed” but “health / medical world” as shown in FIG. When the user notices this and taps "he" in the reading frame, recognition candidates for "he" are displayed as shown in (c). When the user touches and selects the correct hiragana “to” from the recognition candidate sequence in the recognition candidate frame 205, the reading is corrected at that time, and the conversion is executed, and the display changes to a display as shown in (d).

FIG. 20 is an explanatory diagram for explaining the operation of the information processing apparatus according to the present invention when a corresponding postal code is input by inputting a postal code.
The corresponding screen description is shown in FIG. As shown in the example, the "address book application" is activated, and a screen for inputting each item appears. Here, when the user finishes inputting the name and touches the postal code input field of the next address 1 with a pen, the cursor is displayed at the corresponding position, and at the same time, the lot number display frame and the number input frame are superimposed on the input pad area at the bottom of the screen. Is done. After waiting for input, a number is input to the number input box by character recognition.

The input numbers are sequentially displayed in a number input box. Each time, it is determined whether or not the number of digits of the input numeral is smaller than 5, which is the maximum value. If the number is smaller, the process returns to the number input waiting state. Displayed in the display frame. In FIG. 26 (c), a land number character string "Mita City, Hyogo Prefecture" corresponding to the input of the last "3" is displayed. When the confirmation instruction button is tapped here, the postal code of the number input box and the lot number character string of the lot number character string display frame are simultaneously input into the post code field and the lot number field of the address book application frame as shown in FIG. Is done.

FIG. 18B is a flow chart showing the procedure of the abnormal character correction processing. First, in the process of “next kanji extraction”, unprocessed kanji is extracted. For example, when "Saito" is specified, the first character "Sai"
Is extracted. Next, the dictionary shown in FIG. 18A is accessed from the kanji to search for allograph kanji. The kanji which is the key of this allograph dictionary is a kanji to be recognized, and a standard pattern corresponding to 307 is registered. For example, for the Chinese character "Sai", "Sai, Sai" is searched. If there is such an allomorph, it is displayed on the screen as shown in FIG. 24. Therefore, if the user selects a desired kanji, the character of "sai" of "saito" specified in the sentence is rewritten. If there is no allograph, the process proceeds to the next character.

FIG. 29 is an explanatory diagram for explaining a character string text display method in the information processing apparatus. FIG. 29 (a) shows a state where a conventional rasterized character text pattern is displayed on a screen. In order to enhance readability by emphasizing the linearity in the direction of a sentence. In some cases, an interval of several dots is usually provided between lines as a space between lines. In this figure, the text is arranged in the horizontal direction. On the other hand, in the present embodiment, as shown in FIG. 29 (b), the interval between rows is not provided, and the color expression of pixels is changed to emphasize the linearity. This allows
Eliminating the space between lines is unnecessary, and a large amount of text can be displayed in an easy-to-read format on a small screen. FIG. 29C shows a state of displaying the entire text.

In the information processing apparatus of the present embodiment, when the screen format of Japanese text editing is switched to the fine mode, the alternate color switching display appears. The switching instruction, the updating of the font, and the like are performed by a known technique, and a description thereof will be omitted.

[0104]

As described above, according to the present invention, screens that are not used at the same time are displayed in a superimposed manner according to the input state, so that flickering of the screen is suppressed, and the input screen is effectively used, and furthermore, character recognition is performed. The size of the frame can be increased, the shape of the device can be reduced, and the visibility can be improved.

Further, erroneous operation can be avoided by appropriately recognizing the handwriting input and suppressing the display of the result according to the use situation.

Further, by displaying the same function instruction button at a plurality of locations on one screen, the pen movement distance for instruction is shortened, and the cognitive burden of searching for the button is reduced. Especially,
By switching and displaying the recognition button near the handwriting input frame during character recognition writing, the pen movement distance for instruction is shortened, and the cognitive burden of searching for the button is reduced.

Further, by inputting a character that cannot be input as a reject character into the recognition result character string, the fact that the result of character recognition has been rejected can be easily recognized even after the character has been input, and Correction and edit processing becomes easy.

Further, when the time is input, the time is sequentially displayed according to the touch position, so that it is possible to input the time reliably while confirming the input value in advance. In addition, by inputting the hour and minute information separately, the time can be correctly input without specifying the exact input position.

When the same function is repeatedly applied to a character string by designating a character string by a drag operation after designating the function and instructing execution at the timing of pen-off, both the range designation and the execution instruction are performed. Can do it,
There is no need to give a function instruction each time a selection is made. In particular, in the case of performing an allomorph conversion in which characters are input with a small number of strokes that can be input by character recognition and then converted into characters that cannot be recognized, the input operation load can be reduced.

After converting the recognized hiragana characters to kana-kanji characters, the conversion is also performed by an operation for correcting a hiragana recognition error, thereby reducing the burden of operating instructions.

[0111] Also, when a predetermined digit is input, the character string is automatically converted, so that a conversion operation when a fixed character string such as a postal code is determined is unnecessary, and a number and a lot number character string can be created simultaneously. And the operability is improved.

When inputting the pair data, the key input screen is automatically displayed by indicating the coordinates of the key input frame, and by inputting the corresponding pair data simultaneously with the key input, the pair data can be input. Input operations are reduced.

Further, by searching for the corresponding kanji using the recognized character as a key, difficult character input can be facilitated. Further, by allowing the number of strokes to be displayed according to the number of strokes, the knowledge of the exact number of strokes is not required, and the user's knowledge load is reduced, and the operation load such as correction is reduced accordingly. Also, by displaying the radical list on the condition of the position of the radical, the cognitive burden of searching for a desired one from many radicals is reduced.

Further, the text can be displayed in an easy-to-read manner even if there is no line gap or column gap by alternately providing different colors, and the number of characters displayed on the screen increases.

Further, by judging the conversion direction on the condition of the conversion priority and the conversion possibility, there is no useless operation in the character type conversion by the single button instruction, and the operability is improved.

As described above, the information processing apparatus or the information processing method according to the present invention can be very convenient for the user, and the practical effect is extremely large.
