Description

  The present invention relates to a technique for receiving input of a character string handwritten by a user.

  As a technology for accepting user-written character string input, a predetermined number of character input frames in a virtual character string input reception area in which a plurality of character input frames are connected in the horizontal direction are arranged on the display screen. Placed in the input reception area, accepts user handwriting input into each character input frame placed in the input reception area, displays the handwritten input pattern in the character input frame, and in the character input frame In a handwriting input device that recognizes characters entered in handwriting, the character input acceptance frame to be placed in the input acceptance area is input in the left / right / direction according to the user's left / right scroll operation. If the user's handwriting does not occur for a certain period of time after scrolling the acceptance frame or interrupting the handwriting input in the rightmost character input frame, the character input acceptance frame is set to the left Number of characters input acceptance frame Lumpur technique is known (e.g., Patent Document 1).

JP 2005-301406 A

  According to the technique described above, when inputting a character string consisting of more characters than the number of character input frames arranged in the input reception area, handwriting input of characters is performed on all character input frames in the input reception area. If so, scroll the character input frame to the left by performing a left scroll operation or waiting for the elapse of the predetermined time, and make an uninputted character input frame appear in the input reception area. Therefore, it is necessary to input a handwriting of an uninputted character in the appearing character input frame.

  Here, it is preferable to accept the input of the character string by the user's handwriting in a form in which the user can perform a natural writing operation as much as possible in order to facilitate the handwriting input of the user's character string.

  However, according to the above-described technique, when scrolling is performed in accordance with the user's scrolling operation, the user needs to perform the scrolling operation, which is not an ordinary writing operation for writing a character string on paper. It becomes.

  Also, when scrolling is performed by waiting for the elapse of the predetermined period, the user cannot input a handwritten character while waiting for the elapse of the predetermined period. The operation of continuously writing characters like the writing operation cannot be performed.

  Therefore, an object of the present invention is to accept input of a character string by a user's handwriting in a form in which the user can perform a more natural writing operation.

  In order to achieve the object, the present invention displays a display device, a touch panel, and a horizontally long handwriting input area on the display device on a handwritten character input device that accepts handwriting input of a character string, and the touch panel. A hand touch pattern input to the handwriting input area of the user performed by handwriting in the area of the touch panel corresponding to the displayed handwriting input area, and The handwriting input receiving unit that displays a handwritten pattern that has received an input and a handwritten pattern that is receiving an input in the handwriting input area, and the handwriting that is in a non-contact state with the touch panel The movement from the peripheral position of the touch panel area corresponding to the right area of the input area to the peripheral position of the touch panel area corresponding to the left area of the handwriting input area is detected. A movement detecting means for displaying the handwriting pattern in the handwriting input area when the movement detecting means detects the movement. Is provided with scroll means for scrolling so as to move to the left.

  Here, in such a handwritten character input device, in the scroll means, a margin that is an area where the handwritten pattern on the right side of the handwritten input area is not displayed is less than a predetermined size. Only when the movement detecting means detects the movement, the display of the handwriting pattern in the handwriting input area is configured to scroll so that the display of the handwriting pattern moves to the left. Also good.

  Further, the above handwritten character input device is the hand displayed on the rightmost of the handwritten patterns corresponding to the recognized characters displayed in the handwritten input area in the scroll means. You may comprise so that the scroll may be performed so that the display of a handwritten pattern may move to the left end side of the handwriting input area.

  Alternatively, the handwritten character input device described above is the hand displayed on the rightmost of the handwritten patterns corresponding to the recognized characters displayed in the handwritten input area in the scroll means. The scroll may be configured such that the display of the handwritten pattern exits outside the handwritten input area to the left of the handwritten input area and is no longer displayed in the handwritten input area. .

  Here, the above handwritten character input device is provided with character recognition means for recognizing the character represented by the handwritten pattern received by the handwritten input receiving unit, and the character recognition means accepts the handwritten pattern. After the start, when the input of the handwritten pattern to the area separated from the handwritten pattern is started, when the input of the handwritten pattern is stopped for a predetermined period after the start of accepting the handwritten pattern, and the movement When the detection means detects the movement, the character represented by the handwritten pattern received after recognizing the previous character may be recognized.

In the above handwritten character input device, the contact body may be, for example, a user's finger or a stylus pen.
According to the above handwritten character input device, the user accepts input of characters handwritten from left to right in the handwriting input area with a contact body with a finger or a stylus pen, and the contact body is handwritten. If the handwriting input area is moved from the right side to the left side without touching the input area, the display of the handwriting input area is scrolled so that the display moves to the left, and a new handwriting input area is displayed. A margin for handwriting input of characters is generated, and then an operation of receiving input of characters handwritten from left to right with a contact body by the user is performed on the generated margin.

  Therefore, the user writes characters from left to right on the paper, and when the characters are written to the right edge of the paper, move the brush that is not in contact with the paper to the left of the paper, The writing operation is similar to the normal operation when writing characters on paper, in which characters are written from left to right, exceeding the number of handwritten characters that can fit within the size of the handwriting input area. Handwriting input of character strings consisting of characters can be performed.

  As described above, according to the present invention, it is possible to accept input of a character string by a user's handwriting in a form in which the user can perform a more natural writing operation.

It is a figure which shows the process example of the handwritten input reception process which concerns on embodiment of this invention.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 shows a configuration of a data processing apparatus according to the present embodiment.
As shown in the figure, the data processing device 100 operates on a display device 1 such as an LCD, a touch panel 2 arranged on the display surface of the display device 1, a user detection sensor 3, an operating system 4, and an operating system 4. One or a plurality of applications 5.

  The operating system 4 includes an input system 41 that receives character input from the user. The input system 41 includes an input control unit 411, a handwritten character recognition engine 412, a handwritten character recognition dictionary 413, and a predictive conversion engine. 414, a prediction dictionary 415 is provided.

  Here, the handwritten character recognition engine 412 recognizes the character represented by the handwritten pattern on the touch panel 2 using the handwritten character recognition dictionary 413 in which the character pattern characteristics of each character are registered.

  Also, the predictive conversion engine 414 uses the prediction dictionary 415 in which the correspondence between the character string and the predicted character string is registered, and the plurality of characters recognized by the handwritten character recognition engine 412 for the plurality of patterns handwritten. The character string that the user intends to input is calculated as a predicted character string from the character string that is

  However, the data processing apparatus 100 described above is configured by using a computer, and the operating system 4 and the application 5 are realized by the computer executing a predetermined computer program.

  Further, the data processing apparatus 100 is, for example, a data processing apparatus 100 mounted on an automobile, and in this case, the display device 1 and the touch panel 2 are arranged in a dashboard of the automobile as shown in FIG. 2a. The

  Here, the touch panel 2 detects the touch of the user's finger or stylus pen on the touch panel 2 and the touched coordinates. Here, in the following description, a finger or a stylus pen to be brought into contact with the touch panel 2 for input to the touch panel 2 is referred to as a contact body.

  Next, the user detection sensor 3 is a proximity sensor arranged one by one at a position close to the touch panel 2 below the left area and the right area of the touch panel 2, and is a touch panel of the user's hand or finger. The approach to the left end area of 2 and the approach of the user's hand or finger to the right end area of the touch panel 2 are detected without contact. In addition, an infrared sensor, an ultrasonic sensor, etc. can be used as a proximity sensor.

  However, as the user detection sensor 3, as shown in FIG. 2b, the camera 31 that captures the periphery of the display device 1 and the user's hand or finger in the captured image of the camera 31 are image-recognized, and the user's hand or finger A sensor provided with a position detection unit for detecting the position can also be used.

  Alternatively, as the touch panel 2, the touch panel 2 having a hovering detection function for detecting the approach of the contact body to the touch panel 2 in a non-contact manner is used, and the touch body 2 is in a non-contact position. The touch panel 2 may also be used as the user detection sensor 3 by detecting.

  In such a configuration of the data processing apparatus 100, when the input control unit 411 of the input system 41 generates a character input processing start request from the application 5 in response to a predetermined operation by the user, the character shown in FIG. The input window 300 is displayed on the display device 1, accepts input of a character string from the user, and outputs the accepted character string to the application 5 as an input character string.

  As shown in FIG. 3a, the character input window 300 includes a handwriting input area 301, a recognized character display area 302, a predicted character string menu 303, an input box 304, a delete key 305, and a confirmation button 306.

  When the user touches the touch panel 2 and makes a handwriting input in the handwriting input area 301, the input control unit 411 displays a handwriting input pattern in the handwriting input area 301 and a hand to be described later. Perform handwriting input processing to recognize handwritten characters, and place the recognized characters in the recognition character display area below the position where the handwriting input pattern that recognized the characters is displayed. indicate.

  Further, the input control unit 411 uses the predictive conversion engine 414 as a predicted character string that is a character string that the user intends to input from a character string obtained by concatenating characters that have been handwritten in the handwriting input area 301. The calculated predicted character string list is displayed in the predicted character string menu 303.

  Then, as shown in FIG. 3b, if any predicted character string displayed on the predicted character string menu 303 is selected by the user, the input control unit 411 additionally inputs the selected character string into the input box 304. At the same time, the display of the handwriting input area 301, the recognized character display area 302, and the predicted character string menu 303 are erased.

Then, as shown in FIG. 3d, the subsequent handwritten input of characters is accepted.
In addition, when the delete key 305 is operated by the user, the input control unit 411 displays a handwriting input pattern that recognizes a character at the end of the handwriting input area 301 and the character recognized for the character. The display of the recognized character display area 302 is erased. Further, the display of the predicted character string menu 303 is restored to the display that was displayed before the last recognized character was recognized.

  Then, when the confirmation button 306 is operated by the user, the input control unit 411 outputs the character string input to the input box 304 at that time to the application 5 as an input character string.

Here, the application 5 receives the input character string output from the input control unit 411 and processes it.
Hereinafter, the handwritten character input process performed by the input control unit 411 as described above will be described.
FIG. 4 shows the procedure of this handwritten character input process.
As shown in the drawing, the input control unit 411 that has started the handwriting input process starts accepting handwriting input (step 402). Here, the acceptance of handwriting input means that the touch to the coordinates in the handwriting input area 301 detected by the touch panel 2 is accepted as handwriting input, and the coordinates in the handwriting input area 301 detected by the touch panel 2 are received. This is a process of displaying the locus as a handwriting input pattern in the handwriting input area 301. If the user starts handwriting input into the handwriting input area 301 using the touch panel 2 (step 404). It waits for the handwriting input to stop in the handwriting input area 301 (step 406).

  If handwriting input to the handwriting input area 301 is stopped (step 406), a timer for setting a predetermined timeout time (for example, 2 seconds) is started (step 408).

  Then, it is checked whether or not there is enough margin on the right side of the handwriting input area 301 to accept the handwriting input of the pattern for one character (step 410). Here, the margin is an area in which the handwriting input pattern accepted so far is not displayed, and a predetermined length M is used as the size of the margin sufficient to accept the handwriting input for one character. That is, in step 410, when the area between the right end of the handwriting input area 301 and the position advanced from the right end to the left by the length M is an area where no handwriting input pattern is displayed. Then, it is determined that there is enough space on the right side of the handwriting input area 301 to accept handwriting input for one character.

If there is a margin on the right side, the occurrence of the start of handwriting input for the next character (step 412) and the occurrence of a timer timeout (step 414) are monitored.
Here, the start of handwriting input of the next character whose occurrence is monitored in step 412 is, for example, handwriting input to a position that is more than a predetermined distance to the right from the right end of the handwriting input pattern received so far. Detect by the start of.

  If the start of input of the next character occurs (step 412), the handwriting input detected immediately before the stop of the handwriting input detected in step 406 using the handwriting character recognition engine 412 is stopped. The character represented by the handwriting input pattern received after the start of the process is recognized (step 416), and the processing returns to step 406.

  On the other hand, when a time-out occurs (step 414), the handwriting input pattern received after the start of handwriting input detected immediately before the stoppage is indicated until the handwriting input detected in step 406 is stopped. The character is recognized (step 418), and the process returns to step 404.

  On the other hand, if it is determined in step 410 that there is not enough space on the right side of the handwriting input area 301 to accept handwriting input for one character, the start of handwriting input for the next character occurs (step 420). Occurrence of timeout of the timer (step 422) and occurrence of movement of the contact body from the right side area of the input area to the left side area of the handwriting input area 301 without touching the touch panel 2 (step 424) To monitor.

  Here, in step 424, the detection content of the user detection sensor 3 is determined from the approach of the user's hand or finger to the area on the right side of the touch panel 2 in a state where no contact is detected on the touch panel 2. The touch body moves without touching the touch panel 2 from the right area of the input area to the left area of the handwriting input area 301 when the user's hand or finger approaches the left area of the hand Is determined to have occurred.

  However, when the camera 31 and the position detection unit are provided as the user detection sensor 3 as described above, the user's hand detected by the position detection unit in a state where the touch of the contact body is not detected by the touch panel 2. Alternatively, when the position of the finger moves around the handwriting input area 301 from the right area of the touch panel 2 to the left area, the contact body moves from the right area of the input area to the left side of the handwriting input area 301. It is determined that movement to the area without touching the touch panel 2 has occurred.

  When the touch panel 2 having a hover detection function is also used as the user detection sensor 3, in step 424, the position where the contact body detected by the touch panel 2 is approaching in a non-contact manner is on the right side of the input area. When the contact object moves from the left area to the left area of the handwriting input area 301, the contact body moves from the right area of the input area to the left area of the handwriting input area 301 without touching the touch panel 2. It is determined that it has occurred.

  Then, if the start of input of the next character occurs (step 420), the handwriting input detected immediately before the stoppage of the handwriting input detected in step 406 using the handwriting character recognition engine 412 is stopped. The character represented by the handwriting input pattern received after the start of the process is recognized (step 426), and the process returns to step 406.

On the other hand, when a time-out occurs (step 422), the handwriting input pattern received after the start of handwriting input detected immediately before the stoppage is indicated until the handwriting input detected in step 406 is stopped. A character is recognized (step 428).
Then, the display of the handwriting input area 301 and the recognized character display area 302 is scrolled by a predetermined movement amount so that the display moves to the left (step 430).
Then, the process returns to step 404.

  Further, when a movement from the right side of the handwriting input area 301 to the left side of the handwriting input area 301 occurs in a non-contact manner with the touch panel 2 (step 424), it is detected at step 406. Until the handwriting input is stopped, the character represented by the handwriting input pattern received after the start of the handwriting input detected immediately before the stop is recognized (step 428).

Then, the display of the handwriting input area 301 and the recognized character display area 302 is scrolled by a predetermined movement amount so that the display moves to the left (step 430).
Then, the process returns to step 404.

The handwritten character input process performed by the input control unit 411 has been described above.
Note that the characters recognized in steps 416, 418, 426, and 428 of the above handwritten character input processing become characters recognized by the handwritten character input processing, and the recognized characters are displayed in the recognized character display area 302. Is displayed.

  Here, the above handwritten character input process may be a process in which steps 410-418 are omitted and the timer is started in step 408, and the process proceeds to monitoring in steps 420-424 as it is. However, in this case, when a timeout occurs (step 422), the handwriting accepted after the start of handwriting input detected immediately before the stoppage of the handwriting input detected at step 406 is stopped. Recognize the character represented by the input pattern, check whether there is enough margin on the right side of the handwriting input area 301 to accept the handwriting input for one character, and if there is no margin, proceed to step 430. The process proceeds to step 404.

Next, a processing example of the above handwritten character input processing will be described.
Now, as shown in FIGS. 5A, 5B, and 5C, when the user sequentially enters characters in the handwriting input area 301 from left to right, the handwriting input pattern is changed to the handwriting input pattern. In addition to being displayed in the input area 301, characters entered by handwriting are recognized and displayed in the recognized character display area 302.

  Then, as shown in FIG. 5c, after completing the handwriting input to the right end of the handwriting input area 301, the hand is released from the touch panel 2, and a finger as a contact body is not in contact with the touch panel 2 as shown in FIG. 5d. If the character is moved to the left side of the handwriting input area 301 as shown in FIG. 5E, the last handwritten character (“w” in the figure) is recognized and recognized as the handwriting input area 301. The display of the character display area 302 is scrolled by a predetermined movement amount so that the display moves to the left. Here, in the examples of FIGS. 5D and 5E, a predetermined movement amount is displayed in the handwriting input pattern 301 in the handwriting input area 301 (the figure of the handwriting input pattern “w” in the figure). Display) is the amount of movement to the left end of the handwriting input area 301. It should be noted that the display of the last recognized character in the recognized character display area 302 is related to the movement of the handwriting input area 301 in accordance with the movement of the handwriting input pattern in which the last character has been recognized. It moves to the lower position of the handwriting input pattern that recognized the last character.

  Now, by such display scrolling of the handwriting input area 301 and the recognized character display area 302, the area on the right side of the display position after scrolling the handwriting input pattern in which the character has been recognized last in the handwriting input area 301 is , It becomes a margin for handwriting input. Therefore, as shown in FIG. 5f, the user can sequentially enter handwritten characters from left to right in this margin.

The processing example of the handwritten character input processing has been described above.
By the way, in the processing example shown in FIG. 5, the display movement amount in the scroll is moved to the left end of the handwriting input area 301, the display of the handwriting input pattern that has recognized the character at the end. However, as shown in FIG. 6, the display movement amount in the scroll is that the handwriting input pattern display in the handwriting input area 301 that recognizes the last character is the handwriting input area 301. It is good also as the quantity which moves to the position of the left outer side.

  That is, as shown in FIG. 6 a, after the user completes handwriting input to the right end of the handwriting input area 301, the finger as the contact body is released from the touch panel 2, and the finger as the contact body is not in contact with the touch panel 2. If it moves to the left area of the handwriting input area 301 as it is, it recognizes the character (“w” in the figure) that was last input by handwriting and, as shown in FIG. The display is scrolled so that the display moves to the left, and the display of the handwriting input pattern in which the character has been recognized last moves to a position outside the left of the handwriting input area 301.

  As a result, the entire handwriting input area 301 becomes a blank space where characters can be handwritten. Therefore, as shown in FIGS. 6 c and 6 d, the user sequentially enters characters to be subsequently input from the left end of the handwriting input area 301. , You will be able to input handwritten from left to right.

  As shown in the processing example of the above handwritten character input processing, according to the present embodiment, the user accepts input of characters handwritten from the left to the right in the handwritten input region 301, and the finger or stylus. If the contact body such as a pen is not in contact with the handwriting input area 301 and moves from the right area of the handwriting input area 301 to the left area, the display of the handwriting input area 301 is changed to the display. Scroll to move to the left, generate a margin for handwriting a new character in the handwriting input area 301, and then handwritten in the generated margin from left to right by the user The operation that accepts input is performed.

  Therefore, the user writes characters from left to right on the paper, and when the characters are written to the right edge of the paper, move the brush that is not in contact with the paper to the left of the paper, A number that exceeds the number of handwritten characters that fit within the size of the handwriting input area 301 in a writing operation similar to the normal operation when writing characters on paper, such as writing characters from left to right. The handwriting input of the character string which consists of the character of can be performed.

The embodiment of the present invention has been described above.
By the way, although this embodiment showed the case where the handwriting input was carried out from the left to the right, this embodiment is handwritten from the top to the bottom like the vertical writing of Japanese. Even in the case of accepting the input of a character string to be input, it can be similarly applied by switching the left and right and the top and bottom of the above embodiment. In addition, when receiving input of a character string in which characters are handwritten from right to left as in Arabic, the present invention can be similarly applied by switching the left and right in the above embodiment. .
