DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation apparatus suitable for use in a small portable information terminal, and more particularly to a document creation apparatus for inputting characters and designating functions using a handwriting pen.

[0002]

2. Description of the Related Art PDA (Personal Digital Assistant)
) Is a small portable information terminal equipped with various services such as document creation (word processing), communication, text-to-speech, scheduling, etc. to enhance convenience, and the market is expanding mainly in the business field. It is getting. In particular, document creation is a central function, and the pursuit of ease of use has been pursued under the constraints of small portable devices.

In an apparatus for creating a document, input of characters and instructions such as various editing functions are usually performed by using a handwriting pen (hereinafter simply referred to as a "pen"). For these instructions, it is necessary to set the range of the target character. As a method of setting a range, a method of moving a pen on a screen is general [for example, a small portable information terminal “Zaurus” PI-7000 manufactured by Sharp Corporation].
Refer to the instruction manual (1996)].

Usually, a tablet is attached to the entire screen of a display device, and the tablet serves as an input device. The tablet has transparent electrodes arranged in a matrix on the entire surface, and the touched position is recognized by touching the tablet with a pen. Since the tablet is transparent, the screen of the display device can be seen as it is, and the touched characters and various editing instructions are obtained. That is, a handwriting area for characters (for example, an input frame) and a soft keyboard are constituted by the input device and the display device.

[0005] The pen movement is performed on such a screen. That is, in the character string displayed on the screen of the display device, lightly touch the target first character, and continuously move the pen to the target last character while keeping the touch, Release the pen on the last character. By releasing the pen, the target range is determined, and characters in that range are highlighted. Next, various editing buttons displayed on the screen, namely, character recognition, copy, cut, paste,
By lightly touching and releasing the corresponding button among the buttons displaying functions such as deletion once (hereinafter, this operation is referred to as “tap”), predetermined editing is performed on the highlighted character.

The above-described character recognition is an editing function unique to a document creation device of a small portable information terminal, and is implemented for handwritten characters using a pen. The character input is also used in combination with a text character input for selecting (tapping with a pen) a text character generated by a computer from a soft keyboard. The above setting of the target range and various kinds of editing are executed by the character editing device provided in the document creation device.

The above-described conventional range setting has the following problems. That is, the dimensions of the screen of the information terminal are:
It is as small as about 10 cm in width and about 6 cm in height, and a text display area of about 10 lines is provided therein. Therefore, the line spacing is small, and the size of the displayed character is small. When the pen is moved over such a character, the pen is likely to protrude from the last character and touch the next character, or the pen is insufficiently moved to release the pen with the character in front. Also, while the pen is moving, there is a possibility that the adjacent line will be touched due to camera shake, and if the pen may rise even momentarily during the movement, this is set as the final position. In either case, the result of erroneously setting the range is brought about. Further, when the range extends over a plurality of rows, it is not only troublesome to move the pen for a long time, but also the possibility of the above various inconveniences increases. In any case, it is impossible to make corrections on the way, and once inconvenience occurs, resetting is required to return to the beginning.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide an improved document creating apparatus capable of easily setting a character range to be edited. is there.

[0009]

The object of the present invention is to provide a soft keyboard having a button for designating a starting point and a button for designating an ending point, and specifying a starting point for a character to be a starting point in a character string. A start point / end point processing unit that sets the same character as the start point of the edit range by associating the button and sets the same character as the end point of the edit range by associating the end point designation button with the character to be set as the end point in the character string. The problem can be solved effectively by providing the document editing apparatus. The user can select the character to be the starting point, the start point specifying button,
This is because it is only necessary to sequentially tap the character desired to be the end point and the end point designation button with a pen, and the range can be set very easily.

Tapping a character or a button is the most reliable and easy operation in the past, and the range can be designated only by the operation. Therefore, the setting error due to camera shake and the trouble of moving the pen in the case of a long sentence are completely eliminated. Even if you mistakenly tap the end point character and tap a different character, the range setting will not be done unless you tap the end point designation button, so just tap the end point character again. This eliminates the trouble of resetting from the starting point as in the related art.

FIG. 2 shows an example of a screen for inputting a handwritten character using a pen as an example of a screen showing a start point designation button and an end point designation button provided on a soft keyboard comprising an input device 101 and a display device 107. In the figure, 1 indicates a start point designation button, and 2 indicates an end point designation button. At the center of the screen shown in the figure, there is a text display column. In the text display column, text characters input from the soft keyboard and characters obtained by compressing handwritten characters (hereinafter referred to as "stroke characters") are mixed. Is displayed. The text characters are coded text data inside the computer, but the stroke characters are converted into text characters by character recognition, and text data (code) is given.
Stroke characters are stroke data inside the computer.

Referring back to FIG. 1, the document editing apparatus 102 further includes
A known character recognition unit that recognizes stroke characters and a variety of known edit execution units that execute various editing functions other than character recognition (copy, paste, cut, delete, etc.), and a character string whose range is specified And a means for executing copying, pasting, and cutting for a character string whose range is specified.

As a known peripheral, a RAM (Rand)
om Access Memory (104) serves as a memory for managing text data after character recognition, and the auxiliary storage device A (105) stores input data in a flash memory (not shown) in the document editing device 102. ), And the auxiliary storage device B (106) serves as a storage device for storing input data on a PCMCIA card (usually abbreviated as “PC card”) or the like. Using.

Document editing apparatus 1 including start point / end point processing section 103
FIG. 3 shows the structure of 02 including the related peripherals. In FIG. 3, reference numeral 112 denotes a target (character, start point /
The target determination units A and 121 that determine the end point designation buttons 1 and 2 and various editing function buttons) are initialization processing units that control the operation of the determination unit A112, and 113 is a target that is notified from the determination unit A112. In the case of a character, a character position determination unit 114 for determining the position of the character on the display screen is provided by a character position determination unit 113 when the object notified from the determination unit A 112 is the start point / end point designation buttons 1 and 2. A start point / end point determination unit 116 that determines whether the character whose position has been determined as the start point or the end point is an editing function (character recognition, copy , Pasting, cutting, deleting, etc.), the editing function determining unit 117 acquires the set range as an editing target, and
8) or a target data acquisition unit that sends data in the above range to various editing execution units (119).

The input device 101 has a pen input tablet (110) and a coordinate acquisition unit (111), and notifies the determination unit A112 of the coordinates of the tap position. Display buffer (115)
Is a memory of the RAM 104, which temporarily stores data such as displayed characters, start / end point designations, and various editing functions.

In the above structure, the start point / end point determination unit 11
If the character and button to be tapped are a character to be a start point, a start point designation button, a character to be an end point, and an end point designation button, the character whose position is first determined by the character position determination unit 113 is the read start character. Display buffer
It instructs 115 to perform reading, and further instructs display buffer 115 that the character whose position is determined next by character position determining unit 113 is a reading end character, and instructs reading to end. The display buffer 115 outputs the character string data in the editing range according to this instruction. In this way, the start point designation button is associated with the character to be the start point, the same character is determined as the start point of the edit range, the end point designation button is associated with the character to be the end point, and the same character is set as the end point of the edit range It is determined.

The output data of the display buffer 115 is supplied to a target data acquisition unit 117. On the other hand, the editing function determining unit 116
Determines the output destination of the target data acquisition unit 117 so that predetermined editing is performed on the data in the target range acquired by the target data acquisition unit 117.

As described above, the document editing apparatus 102 including the start point / end point processing section 103 sets the character range to be edited in accordance with the input by the tap of the pen, and performs the desired editing on the same range. Processing can be performed.

When a function other than editing (eg, data input, registration, display, etc.) is executed, another object determination unit B120 shown in FIG. Inform predetermined parts to execute the same function for the target data range.

Next, with reference to several screens on the display device 101, the flow of processing of the document editing device 102 including the start point / end point processing section 103 will be described with reference to an example of editing in which characters whose range is set are recognized. .

FIG. 4 shows a screen initially displayed when the power is turned on to the device and the document creation function is selected. The screen displays a list of the titles of the sentences stored in the auxiliary storage device A 105 or the auxiliary storage device B 10 by selecting the buttons “memory” and “card” (tap with a pen) at the upper left of the screen.
The title list of the sentence of the PC card via 6 is displayed,
Whether any of the sentences in this list is to be corrected or a new sentence is to be created is determined by selecting the upper right button “MODIFY” or “NEW”. The screen displays the auxiliary storage device A105
Is displayed as an example.

On this screen, either "correction" or "new" is selected and the process proceeds to the next stage. The screen when the text is being created is the handwriting character input screen shown in FIG. is there. In handwriting, characters are written in an input frame, and the input frame is shown at the bottom of the screen. The written characters are transferred to the sentence display column at the center of the screen automatically or by pressing the "execute" button at the lower right of the screen. At this time, as described above, the handwritten character is reduced in size so as to fit in the line, and becomes a stroke character. Although the stroke characters and the computer-generated text characters are mixed on the screen of FIG. 2, the following description has been made on the case where both are mixed.

Here, character recognition is performed by designating a part or all of the characters in the character string field as a target range. The range is specified by a character to be a start point, a start point designation button 1, a character to be an end point, and an end point. This is performed by sequentially tapping the designation button 2 with a pen, and after confirming the target range, the “recognition” button in the upper right of the screen is tapped. When such range designation is performed, first, the initialization processing unit shown in FIG.
The initialization processing for the start point / end point processing unit 103 is performed by 121.

The initialization processing section 121 is called when the "new" and "correction" buttons are selected in FIG. 4, and enters the operating state. The initialization processing determines the state of the start point / end point processing. The variables that determine the state include "SENTAKU_MODE", "selection information table, start point designation" shown in FIG.
There is "selection information table, end point designation". "SENTAKU_MO
"DE" is "0" when the start point designation button 1 and the end point designation button 2 are not selected, "1" when the start point designation button 1 is selected and the character of the start point is determined, and "1" and end point designation button 2 are set. When the character at the end point is selected and determined, “2” is set. In the “selection information table, start point designation”, “0” is displayed when the start point designation button 1 is not selected, and when the start point designation button 1 is selected, the position of the character tapped to be the start point is set. Information is given. The "selection information table, end point designation" contains "0" when the "end point designation" button is not selected, and the position information of the character tapped as the end point when the end point designation button 2 is selected. Is given.

FIG. 6 shows a processing flow of the structure of FIG. 3 centering on the start point / end point processing unit 103. The processing flow is based on the input device 10
The target determination unit A11 determines whether the information is a tap on the start point designation button 1 (Y) or not (N) through an input processing stage 1101 of coordinate acquisition 111 for acquiring information input from 1.
The process proceeds to the second process 1102. If the tap is on the start point designation button 1, the start position process 1103 is executed by the character position determination unit 113 and the start / end point determination unit 114. If the tap is not a tap on the start point designating button 1, it is a tapping on the end point designating button 2 (Y) or not (N).
Moving to 104, if the tap is on the end point designation button 2, the end point processing 1105 is executed by the character position determination unit 113 and the start point / end point determination unit 114. If it is not a tap to the end point designation button 2, the process proceeds to the processing 1106 of the determination unit A112 for determining whether it is a tap to the "recognition" button (Y) or not (N). The data of the target data acquisition unit 117 is sent to the character recognition unit 118 by the editing function determination unit 116,
Recognition processing 1107 is performed. If it is not a tap to "recognition", no processing is performed, and a state of waiting for the next input is made.

Character position determining section 113 and start point / end point determining section 1
FIG. 7 shows fourteen starting point processes 1103. As described above, when the start point designation button 1 is tapped, the start point processing 1103 is executed. First, a determination 1201 is made as to whether the variable “SENTAKU_MODE” is “0” (initial state) or “2” (range specification final state by specifying the end point). No processing is performed, and the start point processing 1103 ends. If "SENTAKU_MODE" is either "0" or "2", the character being tapped as the start point is highlighted (process 1202). FIG. 8A shows a screen example of the reverse display. Next, the position information of the start point character is given to “selection information table, start point specification” (processing 1203), and “1” (“start point specification” end) is set to “SENTAKU_MODE” (processing 1204). 1103 ends. The position information of the start character is notified to the character position determination unit 113.

The character position determining unit 113 and the start point / end point determining unit 1
FIG. 9 shows fourteen end point processing 1105. As described above, when the end point designation button 2 is tapped, the end point processing 1105 is executed. First, it is determined whether the variable "SENTAKU_MODE" is "1"("start point designation" end state) (Y) or not (N).
If 01 is performed and the start point designation end state is not reached, that is, if the end point designation button 2 is tapped in a state where the start point position is not determined, no processing is performed, and the end point processing 1105 ends. If "SENTAKU_MODE" is "1",
The characters from the start point to the end point are highlighted (process 1302).
FIG. 8B shows a screen example of the reverse display. Next, the position information of the end point character is given to "selection information table, end point designation" (step 1303), and "2"("end point designation" end) is set to "SENTAKU_MODE" (step 1304). 1105 ends. The position information of the end point character is notified to the character position determining unit 113.

FIG. 10 shows a recognition process 1107 of the editing function determination unit 116 and the character recognition unit 118. As described above, the recognition process 1107 is executed when the “recognition” button is tapped.
First, it is determined 1401 whether the variable “SENTAKU_MODE” is “0” (initial state) (Y) or not (N). "0"
In the case of, it is a state where the `` recognition '' button is tapped without performing the range selection, the character string data before the character tapped before tapping the `` recognition '' button is sent to the character recognition unit 118, In the character recognition unit 118, recognition 1402 is performed on stroke data in the same character string. continue,
“SENTAKU_MODE” is set to “0” (process 1409), and the process ends.

If it is not "0", the flow shifts to determination processing 1403 as to whether [SENTAKU_MODE] is "1"("start point designation" end) (Y) or not (N). If the designation of the start point is “1”, only the character at the start point (inverted display section) is targeted, and the data of the same character is sent to the character recognition section 118 and the recognition 140
4 is executed. After the recognition 1404, the inverted display is deleted (processing 1405). Subsequently, "SENTAKU_MODE" is set to "0" in the same manner as described above (process 1409), and the process ends.

If it is not "1", the process shifts to a determination process 1406 as to whether or not (S) "SENTAKU_MODE" is "2"("end point designation" is completed, and thus the range designation is finalized). In the case of “2” for which the range is determined by specifying the end point, the character string from the start character to the end character (inverted display section) is targeted, and the data of the character string is sent to the character recognition section 118 and Recognition 1407 is performed on the stroke data. After recognition 1407, the reverse display is deleted (processing 14
08), The recognition result is displayed. FIG. 11 shows an example of the recognition result screen. Subsequently, "SENTAKU_MODE" is set to "0" in the same manner as described above (process 1409), and the process ends.

The processing of the start point / end point processing unit 103 is the same as that shown in FIG.
a, FIG. 8b, and FIG. 11, the case where stroke characters and text characters are mixed, but the present invention is not limited to this, and the same processing is naturally performed for only stroke characters.

Further, as described above, the above processing
Although the editing is for character recognition, the same processing is performed for various types of editing such as copying, pasting, and cutting. In this case, first, the target range is displayed in a reversed character string by the same type of character range specification method as described with reference to FIG. 6 (the recognition described in FIG. 6 is copied, pasted, cut, etc.). Set as part. The screen is the same as the screen of FIG. 8b, for example. Next, on the screen of FIG. 8B, the "menu" button at the upper right corner is tapped. When the button is tapped, a small menu screen appears at the upper right of the screen as shown in FIGS. 12A and 12B. On the same small screen, there are "Delete", "Copy", "Cut", "Paste", and "Recognition conversion". Is selected, and editing of the item is executed for the above-mentioned reverse display portion. FIG.
a shows a case where “copy” is selected. When "copy" is selected, the highlighted portion is copied to a known clipboard. In the case where "cut" is selected, the inverted display portion is copied to the clipboard in the same manner.

FIG. 12B shows an example of the screen when the user moves the pen to the position where the copy portion is to be pasted and taps it, and then selects "paste" from the small menu screen. The character string of the copy portion is pasted at a position desired by the user.

The above screen example is for a case where both stroke characters and text characters are mixed. However, the present invention is not limited to this case. Can be applied.

Next, the "recognition conversion" of the small screen is an item for the user to set a method of recognizing stroke data. FIG. 13A shows an example of a screen in which “recognition conversion” is selected. By tapping the part where “recognition conversion” is displayed, the conversion small screen of FIG. 13B appears. The user can select a conversion mode of “batch conversion” or “automatic conversion”. In the “batch conversion”, the documents being edited are displayed together without specifying a range, and then batch recognition is performed. In "automatic conversion", the user does not specify a recognition target, but is automatically recognized each time a character is input, and the results are sequentially displayed.

Although these recognition modes are known, in contrast to "automatic conversion", in the present invention, those which require a certain time, such as characters that are difficult to recognize, can be displayed as stroke characters after character recognition. I did it. For this purpose, a means for calculating the recognition time and a switch means for switching the data output from the character recognition section 118 (FIG. 3) to the stroke data input to the recognition section when the recognition exceeds a predetermined time are used. The recognition unit 118 has been added. By this means, it is possible to have a chance to carefully perform recognition later on a character that may cause erroneous recognition.
FIG. 13C is a screen display example including the stroke character.

Further, in the present invention, it is possible to distinguish between text data after character recognition of stroke data and text data obtained by inputting text characters. FIGS. 14A and 14B show examples of the screen for performing the distinction.
b. Since the document editing apparatus 102 manages the character candidates recognized using the RAM 104, the document editing apparatus 102 can arbitrarily recognize the document being edited at any time until the document is registered, and can display the recognition candidate. FIG. 14A is an example of a candidate display screen that recognizes stroke data. The input frame is displayed by moving and tapping the pen in front of the character to be displayed as a candidate, and tapping again. FIG. 14B is an example of a candidate display when a character whose text is input is tapped. In text character input, since there is no character candidate,
A mark indicating that is displayed in the input box. As a result, in the text display after recognition, it is possible to distinguish a result after stroke data recognition, that is, a character having a recognition candidate from a character having no recognition candidate by text character input. Therefore, re-recognition and correction of candidates can be performed at any time.

When registering stroke data and the like as necessary in addition to the edited text data, the "register" button in the upper right portion is selected in the screen example of FIG. At that time, a registration small screen for executing registration is displayed as shown in FIG. In the small screen, "Title name"
In the column, characters selected from the soft keyboard are written in the title name of the registered data. Next, a "memory" button or a "card" button is selected depending on whether the "registration destination" is the auxiliary storage device A105 or the auxiliary storage device B106.

In the present invention, both the "memory" button and the "card" button can be selected. Therefore, when both are selected, both buttons are highlighted, and data to be registered is supplied to the auxiliary storage device A 105 and the auxiliary storage device B 106, and a simultaneous registration means for activating both is provided. This means is that the auxiliary storage device is 2
The present invention can be applied not only to the table but also to more cases.

When the “execute” button is selected after the button of the registration destination is selected in FIG. 15, the data is stored in the registration destination, and the title list screen of FIG. 4 is displayed. If the "cancel" button is selected instead of "execute", the registered small screen disappears and the original input screen (FIG. 2) is displayed.

The other document editing operations and functional operations of the document editing apparatus 102 including the above-mentioned start point / end point processing unit 103 are known. However, just in case, the operations of the document creating apparatus including the known operations are included. An outline of the whole will be described below. Several display screens and flowcharts were used for the description.

First, the input of characters will be described with reference to the screen shown in FIG. “Note” and “Character” at the upper left of the screen are buttons for selecting handwritten character input and text character input, respectively. In the screen of FIG. 2, “Note” is selected by tapping (reverse display). “View” is a button selected when viewing input data. In addition, the above-mentioned “registration” button is located at the upper right of the screen, and a “cancel” button is arranged to the right.
