Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handwriting stroke editing apparatus for editing strokes input by handwriting.

[0002]

2. Description of the Related Art In recent years, a handwriting stroke editing apparatus capable of editing characters and figures input by handwriting has attracted attention. The characters and figures input by handwriting are a collection of strokes. A stroke is a trace of the pen tip from pen touch to pen up is displayed on the display surface. Whether the handwriting stroke editing device treats these strokes as a graphic or as a character It is determined by the person setting the graphic attribute and the character attribute in the block.

A block in which character attributes are set forms a sentence by connecting those blocks and plays a role as a constituent element of the sentence. For example, if a block corresponding to a character (hereinafter, simply referred to as a character) is deleted in a sentence, the handwriting stroke editing apparatus moves another character in the sentence so as to fill the deletion mark. Further, when a new character is inserted into a sentence, the handwriting stroke editing device shifts the positions of other characters in the sentence by the amount of the insertion so that the inserted sentence is opened.

On the other hand, it is important to layout strokes such as how much each stroke included in a block having a graphic attribute is separated or at which angle the strokes are formed, and strokes are deleted from the graphic. Even if the stroke is edited, the handwriting stroke editing apparatus maintains the distance and angle between the strokes in the figure. Therefore, the operator can delete some strokes or add strokes among the strokes forming the existing figure.

In this way, when the character attribute and the graphic attribute are given to each block, for example, a memo is written horizontally from the left side of the screen, and a map indicating the location of the meeting place is drawn on the right side of the screen. It is possible to create a memo in which characters and figures are mixed while using the editing function. Also, make a database of the memos created in this way,
It can be referred to as appropriate.

There are various conventional methods for setting the graphic attribute and the character attribute. As an example of the above method, the operator is allowed to first decide the area for inputting a graphic in advance, and the handwriting stroke editing apparatus sets the graphic attribute to the stroke input by handwriting in the decided area, and other than that. There is a method in which the handwriting stroke editing device sets a character attribute for the stroke input by handwriting in the area.

Secondly, there is a method of instructing the operator whether the attribute of the handwritten information to be input is a character or a figure every time handwriting is input. Thirdly, there is a method in which the input handwriting stroke editing apparatus automatically distinguishes the handwritten information into characters or figures based on the number and length of strokes (for example, "Japanese Patent Laid-Open No. 01-1368").
2 ”). In the automatic discrimination by the recognition process in the third method,
There is a possibility that the figure attribute may be erroneously set due to misrecognition. On the other hand, the first or second method is a graphic attribute,
Character attributes can be set reliably.

[0008]

However, in the conventional handwriting stroke editing apparatus based on the premise of editing characters and figures in the above-mentioned prior art, since the attribute setting is troublesome,
There was a problem that they were shunned by the purpose of writing notes. Because, in writing notes, it is common for the operator to run the pen while thinking about what to write,
In order to do this on the handwriting stroke editing device, it is necessary to easily create figures and characters. Therefore, if it is necessary to explicitly instruct the handwriting stroke editing device to “set attributes from now on” every time handwriting, the operator remembers the troublesomeness of writing notes using the handwriting stroke editing device. I will end up. Alternatively, if the handwriting stroke editing device performs a process different from the instruction by explicitly giving such an instruction, the operator feels frustrated at the handwriting stroke editing device and is forced to make corrections. I shy away from writing notes using an editing device.

According to the present invention, the attribute setting is performed after the memo writing is completed, thereby eliminating the trouble and frustration of the attribute setting at the time of input, and moreover, the attribute setting is surely performed.
It is an object of the present invention to provide a handwriting stroke editing device that allows easy memo writing and facilitates various editing processes.

<Handwriting input processing based on the display example of FIG. 8> Tables from FIG. 8 to FIG. 11 show how the CPU 9 controls the handwriting stroke editing device based on the program stored in the secondary storage device 1. This will be described with reference to the examples. FIG. 8 is a display example showing a state in which a map input by handwriting with a character attribute is changed to a graphic attribute. First, the operator holds the handwriting stroke editing device with his / her left hand and the pen 3 with his / her right hand. It is assumed that the editing device is turned on. After the power is turned on, the CPU 9 displays a menu on the display-integrated tablet 2. This menu contains a character string that prompts the operator to activate which mode of handwriting input processing, attribute selection processing, and editing processing,
When the operator pen-touches any character string with the pen tip of the pen 3 held in the right hand, the CPU 9 reverse-displays the pen-touched character string and executes a process corresponding to the character string.

When it is determined that the handwriting input process is selected (step m4 in the flowchart of FIG. 3), CP
U9 activates the handwriting input processing mode. After the start, when the operator runs the pen tip on the tablet 4, the coordinate values traced by the pen tip are detected by the XY decoder 6 (step u1 in the flowchart of FIG. 4B). The detected coordinate values are stored in the main storage device 8 (step u2), and between the coordinates on the display surface corresponding to the current detected value and the coordinate value corresponding to the previous detected value by the CPU 9. A line segment connecting the lines is drawn, and the line drawing is repeated to form a stroke (step u3).
When the stroke is formed, the CPU 9 determines the length and direction of the off stroke of the stroke input by handwriting, and determines the break of the block (the flow of FIG. 4A).
Chart step t2). When a break occurs, a character attribute is set by using a block of strokes input by handwriting as a block and stored in the block storage unit 7 (step t3). After the block is stored, if the handwriting input end button is pressed, the processing ends, but if not pressed, the input of a stroke is waited for. By repeating such handwriting input, as shown in FIG. 8A, the annotation "here" is drawn in the upper left of the screen, and the annotation "waiting" is drawn in the lower part. Further, a map (a handwritten map in which a railroad line symbol and a road symbol intersect each other corresponds to this) is drawn on the right end of the screen. A character attribute is set for each of the blocks drawn as described above, and the blocks are stored in the block storage unit 7. The broken line in FIG. 8A shows how the character attribute is added to each block. As shown in the figure, it is roughly classified into two blocks, a character part and a map part, and stored. The map at the right end of the screen is also stored in the block storage unit 7 as a block having one character attribute. After storing these blocks, the process returns to the flow chart of FIG. 3 and the mode selection process is performed by displaying the selection menu (steps m4 to m7).

<Selection Process Based on Display Example of FIG. 8 (b)> It is assumed that the operator performs pen touch to set the mode and select the attribute setting process (step m5). When the operator moves the pen tip of the pen 3 after the activation of the attribute setting process (step m2), the CPU 9 gesture-recognizes the trajectory of the pen tip, and in the case of a selection symbol, the circumscribed rectangle of the stroke of the selection symbol. Is read as the selection range (step s1 in the flowchart of FIG. 5), and all the character blocks whose own area is included in the selection range are extracted (step s2). In the display example of FIG. 8B, since the handwritten maps are surrounded by the egg-shaped closed figures, the character blocks forming these maps are taken out. Then CPU 9
Determines whether all or some of the extracted block areas are included in the selected range (step s3). In this case, since the handwritten map in the figure is within the range, the entire character block of the handwritten map is selected as indicated by the arrow pointing to the lower right in the figure (step s3). The graphic attribute is set to the block (step s8), and the graphic block is stored (step s9).

<Editing Process Based on Display Example of FIGS. 9 (a) and 9 (b)> FIG. 9 shows an annotation input by handwriting with a character attribute,
It is a display example for comparing how a map set as a graphic attribute is edited. It is assumed that the operator selects the editing process (step m6), activates the editing process (step m3), and runs the pen tip on the annotation shown in the display example of FIG. 9A. The CPU 9 reads the selection range selected by the pen tip (step p1 of the flowchart of FIG. 6), extracts the block of the selection range (step p2), and performs gesture recognition of the trajectory of the pen tip. (Step b1 in the flow chart of FIG. 7), it is determined whether the symbol is a deletion symbol (step b2). When the pen tip moves in an X shape, the character string "ko" and "ko" that overlaps the trajectory of the pen tip is deleted (step b3). After the deletion, the remaining lower blocks in the sentence are moved so as to fill the deletion mark (step b4). After the movement, whether or not there is a lower graphic block in the character strings "ko" and "ko" is determined (step b5), but since it does not exist here, the process ends.

<Editing Process Based on FIGS. 9C and 9D>
The operator selects the edit process, starts the edit process, and
It is assumed that the pen tip is run on the map shown in the display example of (a). The CPU 9 gesture-recognizes the stroke drawn by the trajectory of the pen tip to determine whether the pen tip draws a V-shape. When it is determined that the V-shape is drawn, a horizontal line (the horizontal line corresponds to the upper side of the road symbol) that is the range designated by the locus is read as the selection range, and the blocks included in the selection range are extracted. Since the graphic attribute is set to the extracted horizontal line block, the CPU
9 deletes the horizontal line.

<Editing Process Based on Display Example of FIGS. 10A and 10B> FIG. 10 is a display example showing a state in which a part of the character block is set to the graphic attribute. First, the operator
It is assumed that the editing process is selected in the main flow chart shown in FIG. 3, the editing process is activated, and the pen tip is run on the map shown in the display examples of FIGS. CPU
9 recognizes a convex closed figure drawn by the trajectory of the pen tip, and reads the range of the circumscribed rectangle of the stroke of the drawn selection symbol as the selection range (see the flow chart of FIG. 5).
In step s1) of the chart, all character blocks that include part of their own area within the selected range are extracted (step s2), and it is determined whether the extracted range is part of the character block (step). s3). Since only a part is included in this display example, the part within the convex-shaped range is separated from the block (step s4). Due to this separation, the character "su" in the figure (this character "su" is distorted to the left because it was input by hand.) And the handwritten white star ("su" Like letters, the left and right sides are tilted downward because they are entered by hand.) After the division, as shown in Figure 10 (c), set the pointer to the block of white ☆ in the lower block information of the block of the character "Waiting here", and set it to the upper block information of white ☆ The inclusion relation between blocks is set by setting the pointer to the block "Waiting here" (step s5). Among the blocks generated by the separation in step s4, the graphic attribute is set to the white starred block (step s6). In addition, the character attribute is set in the block "wait here", and the block in which the graphic attribute and the character attribute are set is stored (step s7).

<Editing Process Based on Display Example of FIGS. 11A and 11B> FIG. 11 is an explanatory diagram showing how a graphic block set as a lower block of a character block moves by editing. . It is assumed that the operator selects the editing process by menu selection, activates the editing process, and runs the pen tip on the annotation shown in the display example of FIG. When the pen tip moves in the X-shape, the CPU 9 deletes the character "MA" that overlaps with the locus (step b3 in the flowchart of FIG. 7), and after the deletion, fills the deletion mark. , Move the rest of the letters in the sentence, "su" (see the flow chart in FIG. 7).
Step b4). When the "su" is moved, the inclusion relation of "wait here" is referred to and it is determined whether or not a lower figure block exists in the remaining lower blocks in the sentence (Fig. 7).
Flow chart step b5). "Wait here"
, There is a white star as a lower block, so
Along with the movement of "su", the white stars below the star are moved to maintain the inclusion relation of each block before the movement (step b6).

<Graphic Editing Process Based on Display Example of FIG. 11C> Since the graphic attributes in the display example of FIG. 11 have the graphic attributes set as described above, they can be edited in stroke units. Therefore, when the operator runs the pen tip, the CPU
A gesture 9 recognizes a convex closed figure drawn by the locus of the pen tip and reads the range of the drawn closed figure as a selection range (step p in the flowchart of FIG. 6).
1). Here, the side that is slightly downward in the figure is selected here, and the selected side is deleted by the editing process.
After the deletion, the operator further runs the pen tip and draws an upward side by moving the pen tip (step p4).

By the above-described editing processing, it is possible to mix graphics and characters, for example, a map is drawn with graphic attributes and annotations are made with the text attributes in the drawn map, and the map and the annotations in the map can be mixed. You can move them together. Furthermore, by inserting or deleting characters, only the annotation can be rewritten without breaking the layout of the map. Similarly, it is possible to mix graphics and characters, such as writing with the character attribute and decorating the written sentence with the graphic attribute. You can also move the sentence and decoration together. Furthermore, the sentence can be rewritten with the decoration of each character.

[0040]

As described above, according to the handwriting stroke editing device of the first aspect and the handwriting stroke editing device of the first aspect, since the graphic attribute is set by the range designation, the graphic attribute Since reliable setting can be done without bothersome and does not irritate the operator,
It becomes easier to write memos using the editing function of figures and characters, and it becomes possible to use the memo writing in the style of running a pen while thinking about what to write and the editing function. Therefore, even an operator who has shunned the handwriting stroke editing device because of the troublesomeness of attribute setting can use the handwriting stroke editing device instead of the memo pad.

Further, according to the handwriting stroke editing apparatus of the second aspect, in addition to the effect of the first aspect, a block consisting of strokes outside the range designated by the range designating means is set to a higher rank, and the block is set. Since the block generated by the generation unit is set as a child, the block generated by the block generation unit can be subordinate to the block having the character attribute. Further, since the block having the character attribute and the block having the graphic attribute generated by the block generating means can be integrated with various editing functions of the handwriting stroke editing apparatus, the convenience of editing is greatly improved.

According to the handwritten stroke editing apparatus of the third aspect, in addition to the effect of the second aspect, the block for which the deletion instruction is given by the deleting means is deleted and the child block whose parent is the block is deleted. Since it is deleted, it is possible to modify the block with the character attribute set with the block with the graphic attribute set, and it is also possible to delete the block with the graphic attribute that is the modification of the block with the character attribute. Therefore, the convenience of editing is greatly improved.

According to the handwriting stroke editing apparatus of the fourth aspect, in addition to the effect of the third aspect, the deletion trace is filled by moving another block in the sentence,
Since the child blocks of those blocks are moved to the destination of the parent block, the block with the character attribute modified by the block with the graphic attribute can be used as a constituent element of the sentence, which improves the convenience of editing. To do.

Further, in the handwritten stroke editing apparatus according to the present invention, a block consisting of strokes within a specified range is generated by the block generation means, a graphic attribute is set in the generated block, and the generated block is generated. Since the graphic attribute set in the block is stored in the storage means, it is possible to partially edit the character in addition to editing character by character. Therefore, it is possible to easily edit the characters and figures input by handwriting, and greatly improve the usability.
