Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention inputs a handwritten character using a stylus pen or the like at an arbitrary position on the screen,
The present invention relates to a handwritten character input device that recognizes the handwritten character, converts it into a character code, and inputs a text, and a computer program that realizes the handwritten character input device. In particular, the present invention relates to a portable handwritten character input device having a small screen and a computer program for realizing the same.

[0002]

2. Description of the Related Art Generally, a handwritten character input device is
Handwriting is input to a transparent tablet that can be displayed using a stylus pen, and handwriting is input to a display of a personal computer using a pointing device such as a mouse or an ordinary pen tablet.

The relationship between the handwritten character input area of the conventional handwritten character input device and the recognition result display area is roughly classified into the following three patterns.

First, the first pattern is a pattern in which an area for inputting handwritten characters and an area for displaying characters as a recognition result are separate areas. The second pattern is
This is a pattern in which an area for inputting handwritten characters and an area for displaying characters as a recognition result are the same area. Third
The pattern is a pattern in which an area in which handwritten characters can be input is the entire screen, and a character obtained as a result of recognizing the input handwritten character is input and displayed in a text input area designated in advance.

In the case of the handwritten character recognition device of the first pattern, since the handwritten character input area and the text input area for inputting / displaying the recognition result are separately located in different areas, the handwritten character input area is the text input area. May overlap on top of. In particular, in the case of the portable handwritten character input device, since the screen is small, this tendency is remarkable, and there is a problem that the input text cannot be seen below the handwritten character input area.

Next, in the case of the second pattern handwritten character input device, since the handwritten character input area and the text input area are the same area, in order to input one handwritten character, at least 1 cm square area is required. If the handwriting input device is a mobile terminal, the screen is small and it is difficult to take a text input area where many characters can be input.
There was a problem that it was a big constraint on the screen design.

Next, in the case of the handwritten character recognition device of the third pattern, conventionally, there are a command mode for starting and terminating a program and designating a text input area, and a handwriting input mode for enabling handwriting input. In order to input a handwritten character, it is necessary to first specify a text input area to be input, then shift to a handwriting input mode, and input by handwriting. Therefore, it is necessary to return to the command mode, specify the text input area to be input next, enter the handwriting input mode, and repeat handwriting input each time the input of one text input area is completed. There is a problem that it is very troublesome to switch the mode and specify the text input area every time the input area changes.

Further, the information processing apparatus disclosed in Japanese Patent Laid-Open No. 7-65114 discloses displaying the recognized character at the start coordinate point of the first stroke of the handwritten character on the screen. ing. However, this is a method for inputting handwritten characters when the entire screen is a text input area only by indicating the display position of the character, and when the text input area is a part of the screen, the text input area is selected. It does not disclose the method.

[0009]

As described above, the conventional methods have various problems regardless of which method is used.
To make it easier for the user to enter handwritten characters, if the entire screen is set as the handwritten character input area, if the text input area is a part of the screen or there are multiple text input areas on the screen, the recognized characters will be There was a problem that it was not possible to specify which text input area to transfer.

As the performance, size, and price of computers have increased as today's computers and portable terminals have become widespread,
If the screen is small and it is difficult to separate the text input area and the handwritten character input area like a mobile terminal, it is effective to make the handwritten character input area the entire screen. If it is a part of the text or there are multiple text input areas on the screen, it is necessary to switch the handwriting input mode and command mode one by one and specify the text input area where the recognized characters should be input before inputting the handwritten characters. Therefore, the operation is troublesome, and it is required to easily specify the text input area to be input and make the handwritten character area the entire screen without switching the mode.

It is an object of the present invention to have few restrictions on the screen design and, when inputting a handwritten character, input the handwritten character while easily designating the text input area without switching the mode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (Embodiment 1) The basic block diagram and processing flow of the present invention will be described with reference to the flowcharts of FIGS.

In the present embodiment, the screen is a transparent tablet, and the text input area displayed on the screen is
A portable device that can use the entire screen as a handwritten character input area will be described as an example of the first coordinate point of the first stroke information of the first handwritten character at which a predetermined coordinate point for determining the text input area is input. The handwritten character input at one time is not limited to one character, and includes a plurality of characters.

In the present embodiment, an example of inputting handwritten characters on a transparent tablet using a stylus pen is given. However, instead of the transparent tablet, handwriting is performed using a pointing device such as a mouse on a display device such as a display device of an ordinary personal computer. Input may be made, a dedicated input tablet may be used for input / display on the display device, or another handwriting input device may be used. The transparent tablet has an input screen and a display screen integrated with each other. When a handwritten character is directly written on the screen using a stylus pen, the written character is displayed as it is.

First, the screen display unit 1 includes a transparent tablet 6
A screen including a text input area is displayed on the screen (step S1). An example of the screen of the transparent tablet 6 is shown in FIG. On the screen, a mode switching button 9 / end button 10, a fixed display character of the input screen, a text input area 8 and the like are displayed on the menu bar. In order to display the screen, the screen display unit 1 has the coordinate data of the text input area 8. In the example of FIG. 3, since the mode switching button 9 and the end button 10 are displayed on the screen, the first coordinate point of the handwritten character cannot be on the button, but it has a key in terms of hardware. In the case of a terminal, if the mode switching button 9 and the end button 10 are assigned to specific keys, the degree of freedom in screen design becomes higher.

Next, the character input section 2 is provided with a transparent tablet 6
The handwritten character input using the stylus pen 7 is received from the screen of (1), the input coordinate point sequence of the handwritten character is input as stroke information, and displayed as it is input on the screen of the transparent tablet (step S2). Then, the input handwritten character is character-recognized by the character recognition unit 3 using the character recognition dictionary 3-1 (step S3).

As the handwritten character recognition method, any of an online recognition method, an offline recognition method, and a hybrid recognition method may be used as the recognition method of each handwritten character, and there is no particular limitation. If there is a frame for inputting handwritten characters, the above recognition method may be applied to the handwritten characters in each frame. It is necessary to separate each character before recognizing.

In order to determine to which text input area the character recognized by handwriting is to be sent, the text input area determination unit 4 determines predetermined coordinate data included in the stroke of the input handwritten character and position information of the text input area. A text input area existing at the predetermined coordinate point is selected based on the coordinate data calculated from (step S4). In the present embodiment, the predetermined coordinate point is set as the start coordinate point of the first stroke of the first input handwritten character, and the text input area at the position where the start coordinate point exists is selected as the text input area to be input. . The input handwritten character data is stored as a time-series coordinate data group in the following structure, for example.

[0030]

[Equation 1]

This expression is a structure defined in C language for storing the input handwritten character data, and x, y
Is a number indicating the x-coordinate value and the y-coordinate value of the coordinate points that make up the handwritten character data, nPnt is the number of coordinate points that make up one stroke of the character, and * pPnt is the number of the coordinate point in nPnt. , NStr is the number of strokes forming the entire input handwritten character, and * pStr is a pointer for indicating the number of strokes in nStr. At the time when handwritten characters are entered, the delimiter for each character is unknown, so one stroke (=
All x, y coordinate points forming an image for each (stroke) are stored as handwritten character data in this array called PATTERN.

Each coordinate data is obtained by acquiring the coordinates of the input handwritten character in a predetermined time unit, and the handwritten character is represented as an aggregate of one or a plurality of coordinate points. The screen display of the characters input by handwriting is performed by drawing a line connecting the coordinate points forming the one stroke based on the data of each stroke. When the handwritten character data is stored in the above structure, the start coordinate point of the first stroke of the first handwritten character is (pattern.pStr [1] .pPnt [1] .x, pattern.pStr
[1] .pPnt [1] .y).

A specific text input area selection method will be described.
Taking (1) of FIG. 3 as an example, when a screen is displayed, the screen is represented by XY coordinates with the origin at the lower left of the screen.
If you hand-write "aiue" on the screen as shown in (1) of Fig. 3, the entered hand-written characters will be displayed in the text input area 1
And passes over the text input area 2. Set the starting coordinate point of the first stroke of the first handwritten character to (250,412)
And XY at the upper left of the text input area of text input 1
The coordinates are (230, 420) and the lower right XY coordinate is (60
0,380), the X coordinate of the start coordinate point is 230
Since it is 600 or more and the Y coordinate is 380 or more and 420 or less, it can be determined that the start coordinate point exists in this text input area. Even when there are a plurality of text input areas on the screen, the text input area to be selected can be specified by performing the same determination in each text input area.

As the coordinate data of the text input area, the coordinate data of the text input area of the screen at the time of creation on the screen display unit 1 is used. The coordinates of the text input area at the time of creating the screen are often character-by-character coordinate data, but in that case, the text input area determination unit 4 converts the data into dot-by-dot coordinate data of the screen for comparison. Of course, the screen display unit 1 may convert the coordinates of the text input area into dot-unit coordinate data and store the data.

The recognized character display unit 5 transfers and displays the character recognized by the character recognition unit 3 to the text input area selected by the text input area determination unit 4 (step S6).
Normally, the display of the handwritten character is erased at this point. In the example of (1) of FIG. 3, the first start coordinate point of the first stroke of the first character of “aiue” input by handwriting is in the text input area of the text input 1, so (2) of FIG. The character code of the character "aiue" recognized as described above is displayed in the text input area of the text input 1.

In this embodiment, the first handwritten character
The text input area existing at the start coordinate point of the stroke was automatically selected as the input area. However, another method may be to select the text input area at the center of gravity of the entire written character string. . In this case, the position of the center of gravity is obtained by the following formula.

[0037]

[Equation 2]

In the above equation, px and py respectively represent the x coordinate and the y coordinate of the barycentric position of the entire written character string. i
Indicates the stroke number of the entire input handwritten character string, and j indicates the coordinate point of each stroke.

In another embodiment, when the coordinates of the input handwritten character first overlaps with the coordinates of the text input area, the text input area can be selected. In this case, it is sufficient to check whether the coordinates of the input handwritten character data are included in the coordinates of the text input area in order from the beginning.

With this configuration, in a handwritten character input device capable of recognizing and inputting handwritten characters or characters at arbitrary positions on the screen, the degree of freedom in screen design is high, and the handwriting input mode and command mode are set for each text input area. It is possible to automatically select the text input area existing at a predetermined coordinate point included in the stroke information of the handwritten character input on the screen as the text input area to be input without switching the It becomes possible to transfer and display.

Second Embodiment In the first embodiment, the method for selecting the text input area to be input based on the position information of the text input area has been described. In the present embodiment, the text input area determination unit 4 transfers the recognized character to the selected text input area and determines whether the character actually transferred to the text input area is read. A method of determining whether or not the region that has been input is a text input region that actually supports handwritten character input will be described. Since only the internal processing of the text input area determination unit 4 is different from the first embodiment, the first embodiment is different.
This will be described with reference to the configuration diagram of FIG.

The feature of this embodiment is that the recognized character is sent to the area on the screen at a predetermined coordinate point and it is judged whether or not the character sent to the area is actually read normally. is there. In other words, if the characters that were sent normally are read into that area, that area is the text input area,
If not read, the area can be regarded as not a text input area.

The text input area is, for example, Windows.
PenSer with ws95 (trademark of Microsoft) standard
It suffices to register a text input component such as Vice's EditBox for handwritten character input. By doing so, it becomes possible to send the result of recognizing the character input by handwriting to the area and input it. Even in the text input area, if the text input parts do not support handwriting input and the settings are such that the keyboard is used for direct input, an error will occur if handwritten input characters are sent out even in the text input area. The return code shown is returned. In this embodiment, by using this function, it is determined whether or not the area at the designated coordinates is a text input area in which handwriting can be input. The area determination logic of the area determination unit 15 will be described below with reference to the flowchart of FIG.

First, the text input area determination unit 4 actually sends the recognized character to the area at the predetermined coordinate point of the handwritten character (step S10). From the area in which the recognized character is transmitted, a return code indicating whether or not the character transmitted to the area is correctly read is received (step S11). It is determined whether the return code is normal (step S12). If the return code is normal (step S12: normal), the designated area is a text input area in which handwritten characters can be input, and the text input area determination processing ends. If the return code is abnormal (step S12: abnormal), the designated area is an area in which handwritten characters cannot be input, and error processing is performed (step S13). Details of the error processing will be described in a third embodiment described later.

As another method for determining whether or not the selected area is a text input area, the recognized character is not sent to the designated area and the text input part is a text corresponding to the handwritten input character. There are a method of determining whether or not it is registered as an input area, and a method of determining the shape of the mouse cursor when the text input area is selected when inputting handwritten characters with a mouse.

A method of determining whether or not the area is registered in the text input part as a text input area corresponding to handwritten input characters will be described below with reference to the flowchart of FIG. For all areas on the screen, the type of area such as a text input area corresponding to handwriting input, a text input area corresponding to keyboard input, or a text output area is registered in advance in the text input part.

First, the handle of the area where the predetermined coordinate points of the handwritten character are present is obtained (step S10a). The type of the handled area is acquired (step S11a). It is determined whether the type of the handled area is registered as a text input area corresponding to handwritten character input (step S12a). When the handled area is the text input area (step S13a: YES), the recognized character is sent to the text input area and displayed. When the handled area is not the text input area corresponding to the handwritten character input (step S13a: NO), error processing is performed (step S14a). The error processing when the designated area is not the text input area will be described in the third embodiment.

Next, a method of determining the shape of the mouse cursor when a text input area is selected by inputting handwritten characters with a mouse will be described. For example, O of a mobile terminal
When S is Windows (trademark of Microsoft) system, if handwritten characters are input with the mouse and the predetermined coordinates are in the text input area, the mouse cursor moves to the text input area, and the shape of the mouse cursor is usually , "I" type, it is possible to determine whether or not it is a text input area by acquiring the handle of the cursor of the GetCursor () function for determining the shape of the cursor and checking the attribute of the cursor. When the mouse cursor moves to the text input area, the mouse cursor itself moves to the beginning of the input area, but even if the mouse cursor moves to the beginning of the text input area, the shape changes to match the text input area. Therefore, it is possible to determine whether or not the mouse cursor is in the text input area. The attribute of the acquired cursor is CURSORINF
It is represented by an O structure, and hCu which is an element in it.
The shape of the cursor can be checked by checking the value of rso r. If the shape of the mouse cursor has been changed, the hCursor of the cursor that matches the shape
You can check the value of. Windows 32 API
In the case of the cursor provided by, it is possible to determine whether or not the mouse cursor is in the text input area by checking whether the value is the same as the value of IDC_IBEAM by setting an appropriate value in the execution environment.

With this configuration, even if the position information of the text input area is not held, it is automatically determined whether or not the area at the predetermined coordinate point of the handwritten character is the text input area by using the text input component of the OS. Can be easily determined.

(Embodiment 3) In the present embodiment, since the predetermined coordinate points of the input handwritten character in Embodiments 1 and 2 do not overlap the text input area on the screen,
An example of the case where the text input area cannot be automatically selected will be described based on the first embodiment. The configuration diagram and processing flow of this embodiment will be described with reference to FIGS. 6 and 7. The same parts as those in the first embodiment are given the same numbers and their explanations are omitted. FIG. 8 is an example of a screen of this embodiment.

Steps S20 to S22 in FIG. 7 are the same as steps S1 to S3 in FIG. 2, and the description thereof will be omitted.

Even if a handwritten character is input, the handwritten character is
As shown in (1) of FIG. 8, when the text input area on the screen does not overlap and the text input area for transferring the character recognized by the text input area determination unit 4 cannot be automatically selected (step S23: NO). Shows the recognized character temporary display unit 12 as shown in (2) of FIG.
Is newly opened and the recognized character is displayed there (step S26). Step S23 corresponds to steps S10 to S12 in the second embodiment.

The text input area instructing unit 13 receives an instruction of the text input area to be input from the user, as shown in (3) of FIG. 8 (step S27). When switching to the command mode for receiving an instruction from the user, when the recognized character temporary display unit 12 is displayed and a state of waiting for an instruction in the text input area is entered, the handwriting input mode is automatically switched to the command mode. , When the text input area to be input is designated by the stylus pen 7 or the like, the handwriting input mode is automatically returned. Therefore, it is not necessary to manually switch the modes. In addition, the frame of the text input area designated at this time may be made thick or have high brightness to clearly indicate the selected area to the user.

In the text input area instruction section 13, even if the text input area is instructed by the stylus pen in the state of waiting for the instruction, the mode is switched to the command mode. Therefore, the text input area is not regarded as the character input and the text input area is designated Regarded as
The text input area is determined based on the instructed coordinate data, the recognized character and the instruction of the text input area to be input are passed to the recognized character display section 5, and as shown in (4) of FIG. 5 transfers and displays the recognized character in the designated text input area 8 (step S28).

Here, the OK button and the Cancel button are displayed on the separate window 12 together with the recognized characters. After this, if there is no problem with this, the OK button is pressed (step S29: YES) to erase the other window 12 (step S31), and when the transfer of characters is stopped, the Cancel button is pressed (step S29:
By NO, the characters transferred to the text input area 8 are deleted (step S30), and the separate window 12 is deleted (step S31). The error processing in step S13 of the flowchart of FIG. 4 of the second embodiment corresponds to steps S26 to S31.

Other than this method, the character recognized unconditionally may be transferred only by designating the text input area 8 to be input with the stylus pen 7 without providing the OK button. Transfers when pressed, Ca
When the ncel button is pressed, another window 12 may be erased without transferring the characters.

When the text input area for transferring the characters recognized by the text input area determination unit 4 can be automatically selected (step S23: YES), processing steps S24-
Step S25 is step S4 to step S5 of FIG.
The description is omitted here.

In the present embodiment, when the predetermined coordinates of the input handwritten character do not overlap the text input area, the user is prompted to input the text input area. However, there is only one text input area on the screen. If there is only one, it may be determined that the text input area is unconditionally designated without receiving an instruction from the user. Alternatively, it may be determined that the text input area closest to the predetermined coordinates is designated.

Further, in the present embodiment, when the text input area cannot be selected, the recognition character is temporarily displayed in another window, and when the text input area of the transmission destination is selected and the recognition character is transmitted, Cancel is performed. Although it can be done, since the text input area was correctly selected from the beginning and the wrong character was sent after the recognized characters were automatically sent, the character sent immediately before was Canceled.
You may want to e. In order to deal with such a case, a recognition information holding unit (not shown) for holding the stroke information of the character transmitted immediately before and the stroke information of the handwritten character in the character recognition unit 3 and a recognition result cancel button are provided, By pressing the recognition result cancel button after transmitting the recognition character, the recognition character transmitted immediately before is deleted from the text input area, and the stroke information of the handwritten character can be restored. The recognition result cancel button may be provided as a hardware button other than the screen or a software button on the screen. The stroke information of the sent character and the handwritten character may be held only for the immediately preceding one or a plurality of times. In the case of holding the recognition result plural times, each time the recognition result cancel button is pressed, the previous input state is restored. Redisplay of the input handwritten character may or may not be performed. As a result, even after the recognition character has been transmitted, the recognition character transmitted immediately before can be cleared, and the selection from the character candidate as the recognition result can be redone or canceled again.

With this configuration, in a handwritten character input device capable of recognizing and inputting a handwritten character at an arbitrary position on the screen, even if there is no text input area at a predetermined coordinate point of the handwritten character, it is recognized temporarily. By displaying the characters in a separate window and instructing the text input area to be input after that, even if you make a mistake in specifying the text input area with handwritten characters, there is no need to manually switch between the command mode and the handwriting mode. You can specify the text input area in.
