Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handwritten information input device for recognizing and processing characters, figures, etc. by handwriting input from a pen or the like.

[0002]

2. Description of the Related Art Conventionally, handwritten handwriting displayed on the display means of a handwritten information input device (so-called pen computer) is regarded as a collection of dots (dots), and each dot is independent. . When erasing the handwritten handwriting displayed on the display means, for example, when erasing the handwriting written with a pencil or the like on a so-called paper with a so-called eraser, for example, it functions as an eraser. By passing an existing pen or the like over the displayed handwritten handwriting, the handwritten handwriting is erased. Therefore, the individual dots forming the handwritten handwriting on the display means are independently erased along the trajectory of the pen having the eraser function. In other words, the individual dots forming the handwritten handwriting that the pen having the eraser function does not pass through will not disappear.

[0003]

For example, as shown in FIG. 6A, when the character string "Earth was blue" is displayed on the display means of the handwriting information input device, this "Earth is blue" is displayed. The word "blue" in "was blue"
Suppose that the pen having the function of the eraser is to be erased, and the pen having the eraser function is passed, for example, as shown by a passage locus PS shown in FIG. 6B. in this case,
As described above, the eraser function allows individual dots under the pen (eraser) passage locus to be individually erased.

That is, as shown in FIG. 6C, each dot in the portion corresponding to the passage locus PS in FIG. 6B is erased. In the example of FIG. 6, the letter B of “blue” is used.
Despite wanting to erase only a, the above passage locus P
S is "ha" and "ka" on both sides of the above "Blue" character Ba.
Since it also covers a part of the character, the dots forming the part of “ha” and “ka” are also erased.

Further, as shown in FIG. 6B, even if the pen having the eraser function is passed once, all the dots of the character "Ba" of "blue" cannot be erased as shown in C of FIG. Therefore, in order to erase all the dots of the "blue" character Ba, it is necessary to trace over the unerased portion of the "blue" character Ba with the eraser function pen a plurality of times. I won't.

As described above, in the conventional eraser function, when, for example, only one character of a character string input by handwriting is erased, there is a possibility that even a character adjacent to the character to be erased may be erased, and Since each dot forming one character must be erased individually, a plurality of dots on the character can be erased until all the points forming the one character are erased using the eraser function pen or the like. It has to be passed twice and is very difficult to operate. It should be noted that such a conventional eraser function is substantially the same as the function of a normal so-called eraser that erases handwriting on paper.

Further, although the above description describes erasing only characters, this is a problem not only for characters but for all handwriting input such as handwriting.

In view of the above, the present invention provides a handwriting information input device capable of easily and without error erasing characters and handwritings by handwriting displayed on the display means. Is intended.

[0009]

A handwriting information input device of the present invention is proposed to achieve the above-mentioned object, and a recognition means for recognizing a character and / or a graphic for which handwriting is input, First storage means for storing the information of the recognized character and / or graphic, and second storage means for storing the information of the character and / or the graphic input by handwriting as they are, And / or graphics and display means for inputting handwritten characters and / or graphics, and the user recognizes the unit of the recognized characters and / or graphics, or the above recognition. The erasing is performed in a predetermined part of the written character and / or figure or in a unit of combination of the parts.

Here, the handwriting information input device of the present invention further performs the following. That is, second recognition means for recognizing characters in character units, Kanji character deviations, creations, or parts units, and figure recognition in parts units, and the above-described recognized one character unit, Kanji character deviations, creations. Alternatively, a third storage means for storing information on a part-by-part basis is provided, and the erasing is performed on a character-by-character basis, a deviation of kanji characters, construction, or a component unit.

Further, a third recognizing means for recognizing a change in the input direction or the number of drawing instructions in a predetermined direction is provided, and the erasing instruction is the change in the direction or the number of drawing instructions in the predetermined direction. To do. Further, a clock means is provided so that the designated character or figure is erased or erased if left for a predetermined time from the first instruction of erasing.

Further, there is provided partial erasing means for partially erasing the character or figure for which the erasing instruction has been given, and when the erasing instruction is given, the character or figure is partially erased by the first instruction. To display. Further, a detecting means for detecting the special symbol or the special character, and a fourth storing means for storing information on how to erase when the special symbol or the special character is detected by the detecting means are provided, and the unit of the erase is , The range delimited by the above special symbols or special characters.

Further, a detecting means for detecting a space and / or a hyphenation symbol is provided, and the erasing unit is
Either delete the character string enclosed by the space, delete from the space to hyphenation, or delete from the hyphenation to space. The erased character or graphic is either a character or graphic before or after recognition.

[0014]

According to the handwritten information input device of the present invention, a character and / or a graphic drawn by handwriting on a screen is recognized, and a unit of the recognized character and / or graphic is recognized by a user's deletion instruction. Alternatively, the erasing is performed in a predetermined part of the recognized character and / or figure, or in a unit of a combination of these parts. Therefore, for example, if the character is erased character by character, only the character desired to be erased can be accurately erased by the user's instruction to erase.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a handwriting information input device of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the handwriting information input device according to the embodiment of the present invention has a function as a recognition means for recognizing a character and / or a graphic input by handwriting, a CPU 51 for controlling each unit, and a dictionary table in advance. As first storage means for storing character and graphic information and reading the character and / or graphic information from the dictionary table in accordance with the recognition result of the handwritten input character and / or graphic. For example, the system ROM 52 (or a work RAM 5 for storing character and / or graphic information corresponding to the recognition result extracted from the system ROM 52)
5), for example, a work RAM 55 as a second storage means for storing the information of the characters and / or the graphic input by handwriting as it is, and the handwriting character and the display of characters and / or graphics. If the user gives a deletion instruction by using a stylus pen 60 which is an input means having an eraser function, the display / tablet block 59 is provided as a display means for inputting / or a graphic. In response to an erasing instruction using the stylus pen 60, the CPU 51 erases in units of the recognized characters and / or figures, or predetermined parts of the recognized characters and / or figures, or a combination of the parts. Is to do.

The handwriting information input device of the embodiment of the present invention will be described in more detail below.

That is, the CPU 51 of the apparatus of this embodiment.
Recognizes a character on a character-by-character basis, a Kanji deviation, construction, or a component unit, and recognizes a graphic on a component unit basis (second recognition means). Further, the ROM 52 is
The dictionary table also stores information on a character-by-character basis, Chinese character deviation, construction, or character and figure component units (third storage means). Therefore, the recognized character can be erased in any of the above-mentioned one-character unit, Chinese character deviation, construction, or component unit, and the figure can also be erased in component unit.

Further, the CPU 51 recognizes a change in the direction of input by the stylus pen 60 having the eraser function or the number of times of drawing instructions in a predetermined direction (third step).
Recognition means). In this case, the erasing instruction is given by the change of the direction or the number of times of the drawing instruction in the predetermined direction. That is, when the direction of the eraser stroke with the stylus pen 60 having the eraser function changes with respect to the first stroke, or when the stroke in the predetermined direction is performed a predetermined number of times, the deletion instruction is given. to decide.

At this time, the apparatus of this embodiment also has a timer 70 as a clock means, and the CPU 51 determines the first instruction (stroke) based on the time information from the timer 70, and the first instruction is made. When it is left for a predetermined time from, the designated character or figure is erased, or the deletion is canceled. Also, the CPU 5
1 also operates as a partial erasing means for partially erasing the character or figure for which the erasing instruction has been made. Even in the case of the erasing instruction in this case, based on the time information from the timer 70. The first instruction (stroke) is determined, and a predetermined portion of the character or graphic is partially erased and displayed by this first instruction.

The RAM 55 also stores information on how to erase when a special symbol or a special character is detected (fourth storage means). At this time, the CPU 5
1 recognizes a special symbol or a special character, and the erasing unit is a range delimited by the special symbol or special character.

Further, the CPU 51 also detects a space and / or a hyphenation symbol. At this time, the unit of erasing is either erasing the character string surrounded by the space, erasing from the space to hyphenation, or erasing from the hyphenation to space.

In the apparatus of this embodiment, the erased character or graphic may be either a character or graphic before or after recognition.

Here, the above can be realized because the characters and figures are handled as follows in the apparatus of this embodiment.

That is, a character or figure drawn by handwriting on the screen (that is, an input handwriting) is a locus of a simple set of dots (dots) on the display screen, and this locus is recognized as a character or a figure. In this case, one character or figure can be cut out according to handwriting information. In other words, the character or figure after recognition can be separated by the above-mentioned "make", "hen", parts, etc. of the character or figure.

From the above, the apparatus of the present embodiment, as described above, recognizes these characters and the like, for example, as "characters" or "pencils" or "characters" by performing the recognition after recognition or even with handwriting. In the situation in which the strokes are divided into "strokes" or "parts" or a series of stroke groups similar to them, a specific portion of the area of the series of stroke groups is once input with a so-called eraser function input device (such as the stylus pen 60) or The entire stroke group can be erased by passing the stroke multiple times.

Further, for the above series of stroke groups,
When erasing is to be realized by passing the specific area a plurality of times by the eraser function input means, it is possible to partially pass through the area including a series of strokes when the eraser function input means has passed. I also make it clear by deleting. That is, in the case where the eraser function input means is passed through the above-mentioned plurality of times for erasing, the passage condition is not satisfied the necessary number of times, but the eraser function input means has passed at least once. In such a case, the above-mentioned partial deletion is performed as a display showing that state. At this time, a certain fixed time is set in advance in consideration of a case where the input means of the eraser function does not pass the necessary number of times and the fixed time is set in advance. The fact that it is currently being erased is canceled, and the display is restored to the original handwritten state.

The handwriting information input device of this embodiment will be described below in detail. The apparatus of this embodiment is shown in FIG.
As shown in, a tablet provided on the display / tablet block 59 as a coordinate input means for generating coordinate data according to a handwriting input trajectory (handwriting) by the stylus pen 60, a tablet controller 58 for controlling this tablet, and A liquid crystal display provided together with the tablet on the CPU 51 and LCD controller 57 that also functions as display data generation means for generating display data based on coordinate data, and the tablet controller 58 as display means for performing display based on the display data. Part (LCD; liquid crystal display),
The stylus pen 60 has a mode switching button for switching the function of the stylus pen 60 to the mode of the handwriting input function or the mode of the eraser function. The mode switching button may be arranged on the keyboard 54 or the like, provided on the stylus pen 60 itself, or displayed in a predetermined area on the display screen.

That is, in FIG. 1, the apparatus of the present embodiment controls the above-mentioned C for controlling each constituent element via the main bus.
In addition to the PU 51 and the system program, the system ROM 52 serving as the storage unit that stores information of a plurality of predefined editing calibration symbols (so-called gestures), character information, dictionary information (the dictionary table), and the like.
And a work RAM in which the handwritten input (handwriting), data after its recognition, various kinds of in-process data, etc. are written / read out.
55, a display / tablet block 59 including the liquid crystal (LCD) display section and the doublet, a stylus pen 60 as a pen input means, and the display / tablet block 59 connected to the CPU 51 via a main bus. A tablet controller 58 that is connected and controls the tablet, and an LCD that is connected to the CPU 51 via the main bus and that controls the liquid crystal display section of the display / tablet block 59.
A controller 57, a video RAM 56 controlled by the LCD controller 57 and the CPU 51 for writing / reading out image display data, and a keyboard 54 for accepting user's character input and editing operation by keystrokes of keys.
A keyboard controller 53 for controlling the keyboard 54, a mode switching button for switching the mode of the function of the stylus pen 60, and a calendar timer 70 for generating time information serving as a reference for operation timing of each part, date and the like. It is a thing.

The CPU 51 recognizes the pen input handwriting shape based on the coordinate data as described above, and recognizes the handwriting recognized from a plurality of gestures (editing constituent symbols) stored in the system ROM 52. The process of reading out the gesture most similar to the shape is also performed.

Next, the erasure of the above-mentioned characters and the like in the apparatus of this embodiment will be described with a specific example.

For example, as shown in FIG. 2A, a character group (character string) "Earth was blue" is handwritten on the liquid crystal display on the tablet block 59, which is displayed by handwriting. It is assumed that the character string of is displayed.

Here, the stylus pen 60 (not limited to the pen only) having the eraser function of the present embodiment is used for the "Blue" character Ba in the "Earth was blue" character group shown in FIG. 2A. , Other means having an eraser function may be used,
In the present embodiment, the case where the stylus pen 60 is used as an eraser by changing the mode has been described. ) Will be described.

Incidentally, as described above, the point cloud (dot group) which has conventionally existed in the passage locus PS of the stylus pen 60 having the eraser function or in the band area including the passage locus PS is erased. It is supposed to be done. However, as described above, for example, even if it is a handwritten trajectory,
Due to the character recognition function of the device, the handwritten handwriting is segmented into character units to some extent (that is, stroke groups of input handwriting are grouped). Under such a situation, it is not efficient to randomly erase a character portion irrespective of the segment of the character by the eraser passage trajectory as in the above-described conventional example. Therefore, for example, if stroke groups such as handwriting are grouped in "character" units (or "making" or "pencil" units that form a character as described later) segmented by the positional relationship, etc. When the stylus pen 60 having the eraser function passes through a specific area including the stroke group (for example, a specific area EB shown in B of FIG. 2 described later), the entire stroke group (area EA shown in B of FIG. 2 described later) is passed. It is more efficient to erase all strokes inside). In the present embodiment, the specific area EB is a quadrilateral area having a half side length and sharing a diagonal line with a quadrangle (that is, an area EA) circumscribing a character composed of a stroke group of handwriting. Of course, the specific area EB is not limited to the above-mentioned quadrangle, and may be a round shape or the like, and the size thereof may not be half the length of the above-mentioned side. Furthermore, the specific area EB can be set to have a different shape and size after each character.

Therefore, in this embodiment, as shown in FIG.
As shown in B of FIG. 7, an area EA that covers all of the characters in each of the character groups and an area EA
A specific area EB in the area (for example, an area including the center of the character), and the specific area EB in the area EA
When S passes, only the characters in the area EA including the specific area EB are erased, for example. That is, in the example of B of FIG. 2, the passage trajectory PS is “ha”.
While passing through the respective areas EA of the character of "," the character of "blue" and the character of "ka", each "ha", "blue",
It also passes over the character "ka" (on the strokes that make up the character). However, the passage locus PS has a specific area E
For B, it passes only on the specific area EB corresponding to the character “blue”. In such a case, in the present embodiment, the area EA including the specific area EB through which the passage trajectory PS passes.
Erase only the letters inside (that is, the letters "blue"). As a result, in the present embodiment, as shown in FIG. 2C, only the character "blue" is erased, and the remaining character group "Earth was bad" is not erased by mistake. In other words, although the passage locus PS also extends over the strokes of the characters "ha" and "ka" as described above, the passage locus PS of the characters "ha" and "ka" passes through. Dots will no longer be erased.

In the example of FIG. 2 described above, when the stylus pen 60 having the eraser function passes over the specific area EB once, the case where the character corresponding to the specific area EB is erased has been described. If the character is erased only by passing the stylus pen, the stylus pen 60 having the eraser function may be mistakenly passed so that the character that should not be erased may be erased. For this reason, in the present embodiment, it is possible to erase the corresponding character only when the stylus pen 60 having the eraser function passes over the specific area EB a predetermined number of times (for example, twice or three times). is there. At this time, for example, how many times (including once) has already been performed, the specific area EB
If the stylus pen 60 having the eraser function is passed and the corresponding character is finally erased by the remaining one pass, the user should be visually aware of that fact. To do. For example, as shown in A of FIG. 3, all or part of each dot forming the character (for example, the character “Bb” of “blue”) is erased in a puddle shape (puddle pattern). As a result, the "blue" character Bb is visually apparently lighter in density than the other characters, and thus can be visually recognized by the user. More specifically, for example, the specific area EB
In the case where the corresponding character is erased when the stylus pen 60 having the eraser function passes twice above, for example, in the first passage, the character (for example, as shown in A of FIG. 3) is deleted. When the "blue" character Bb) is brought into the above-mentioned puddle display state and the stylus pen 60 having the eraser function passes again, the character is erased.

In FIG. 3A, the dots of the character to be erased are erased in a puddle shape to reduce the apparent darkness of the character. For example, in FIG. It is also possible to erase only half of the character in the horizontal direction (vertical direction or diagonal direction) as indicated by the character Bc of "blue". Furthermore, in addition, it is possible to select various methods such as changing the color of the character to be erased.

As described above, the stylus pen 60 having the eraser function is erased before it reaches a predetermined number of times (for example, immediately before), that is, the characters Bb and Bc of A and B in FIG. 3 are erased. The state (character) for more than the specified time (for example, 10 seconds or 1 day) in the state before
If the stylus pen 60 having the eraser function is left without being passed (that is, not erased) for the remaining one time, the stylus pen 60 having the eraser function may be left.
Is recognized as an incorrect passage (that is, the character should not be erased), and the original display of the characters Bb and Bc of A and B in FIG. It is also possible to automatically perform the process of returning to the state A) of 2.

As a result, it is possible to prevent erroneous deletion of the above-mentioned characters, and also to prevent characters adjacent to the character to be deleted from being deleted, for example, even characters that are not desired to be deleted. That is, the stylus pen 6 having the eraser function described above.
Even if the passage locus PS of 0 passes even over the specific area EB of the character which is not to be erased and is adjacent to the character to be erased, the stylus having the eraser function is moved over the specific area EB of the character which is not to be erased. If the pen 60 has not passed the predetermined number of times and the specified time has elapsed, it is possible to prevent erroneous erasing of the character that is not desired to be erased (cancel erroneous erasing).

Further, in the example of FIGS. 2 and 3 described above,
One specific area EB is set for one character, and when the stylus pen 60 having the eraser function is used to erase all the one character, for example, "making" or " It is also possible to erase in units of "hen". Of course, "creation" and "hen"
Not limited to this, it is also possible to erase a portion corresponding to these. In this case, a plurality of specific areas for the one character are provided in correspondence with the "make" and "hen" that make up the character.

For example, as shown in FIG. 4, for "blue" characters, specific areas EB1 and EB2 are provided, for example, as shown in A of the figure, and only the portion corresponding to the specific area where the passage locus PSa is erased is erased. To do. In the example of FIG. 4, the specific area E
Since the passage trajectory PSa is applied only on B2, only the portion (“month”) below “blue” is erased as shown in B of FIG.

Even in the case of erasing "make" or "pencil" as in the example of FIG. 4, as described above, a visual display of a erasure waiting state for the user, such as a puddle-like erasure, or the above It is possible to apply prevention of erroneous erasure for a specified time.

Next, the erase operation will be described with reference to the flow chart shown in FIG. In this flowchart, a character is input in step S1, and in step S2, the input is recognized to perform segment processing in character units. It should be noted that, in this step S2, it is also possible to perform processing in the case where a segment in units such as "make up" or "hen" is mixed in, not in a segment in complete character units. In the present embodiment, the processing is performed as "characters" including these "make" and "hen".

In the next step 3S, the specific area of each character is set. In the present embodiment, as described above, the specific region is, for example, a quadrangle region having a half side length sharing a diagonal line with a quadrangle circumscribing a character composed of a stroke group of handwriting. In step S4, the eraser stroke is awaited.

In step S5, for example, the stroke of the stylus pen 60 having an eraser function (eraser stroke)
It is determined whether or not is input. This step S
When the eraser stroke is input in step 5 (Ye
s), the process proceeds to step S6, and if no input is made, the process proceeds to step S10 described later.

When it is determined Yes in step S5, in step S6, it is determined whether or not a specific region of the character exists on the locus of the eraser stroke. If No is determined in this step S6, the process proceeds to step S10 described below, and if Yes is determined, the process proceeds to step S7.

In step S7, it is determined whether or not the character corresponding to the specific area on the locus of the eraser stroke is already in the puddle display state. In the present embodiment, as described above, for example, when the locus of the eraser stroke once enters the specific area, the character is displayed as a puddle and is erased the second time. Further, when the interval between passages of the first and second eraser strokes exceeds, for example, 10 seconds, the puddle display is returned to the original display and the character erasing process is canceled. When it is determined in step S7 that the corresponding character is not in the puddle display state, step S8
Then, in step S8, the corresponding character is set to the puddle display state. After this step S8,
Return to 4.

On the other hand, if it is determined in step S7 that the corresponding character is already in the puddle display state, the process proceeds to step S9. In step S9, all stroke point sequences forming the corresponding character corresponding to the specific area are erased. Then, it returns to step S4.

When it is determined in step S5 that the eraser stroke has not been input (No), and when it is determined in step S6 that the specific area of the character does not exist on the locus of the eraser stroke (No). In step S10), it is determined whether or not there is a character in the puddle display state. If it is determined in step S10 that there is no character in the plover display state (No),
Returning to step S4, if it is determined that there is a character in the puddle display state (Yes), the process proceeds to step S11.

In step S11, it is determined whether or not the character in the puddle display state remains in the puddle display state for 10 seconds or longer. If it is determined in step S11 that the puddle display state has not been set for 10 seconds or more (No), the process returns to step S4, and 10
When it is determined that the display has been displayed for more than a second (Ye
After step s), the process proceeds to step S12.

In step S12, the puddle display state is canceled, the handwriting is restored to the initial handwriting, and then the process returns to step S4.

As in the above-described embodiment, the individual points (dots) displayed on the display means are grouped into a group, and an erase command is executed for the group to make the whole group. In addition to deleting all strokes at once, for example, a series of strokes recognized as "character", "make", "hen" or similar to them are automatically cut out, At present, there is no existing device which erases a preset specific area including the eraser (or the stylus pen 60 in that state). Furthermore, when erasing all the dots of a character, it is necessary to make a plurality of passes with the eraser (or the stylus pen 60 in that state) as in the present embodiment, and the trace of the pass can be visually recognized. There is no such thing.
