Next, the character input process of the handwritten character input device 1 of the present embodiment will be described.
FIG. 5 is a diagram showing an outline of the character input process of the handwritten character input device 1 of the present embodiment. As illustrated in FIG. 5A, the character “now” is input by handwriting in the first input frame 511-1 of the character input area 51 in a state where nothing is input. As a result, as shown in FIG. 5B, the characters “now” are displayed in the input frame 511-1 in a shape as drawn by hand. At this time, in the prediction candidate area 53, a character predicted from the characters “now” is displayed. In this example, “Today”, “Now”, “This time”, “This year”, “This time”, “Future”, “This week”, “This month”, and “This morning” are displayed. Next, when hand is to be handwritten in the next input frame 511-2, the hand is released from the input frame 511-1 and the character is written in the next input frame 511-2, as shown in FIG. At the beginning of writing a new character, the previously input “now” character is confirmed and changed from a handwritten handwriting to a font format, and “now” is first written in the prediction candidate region 53. A part of the character (“1”) is displayed. Thereafter, character input is performed in the same manner. FIG. 5D shows a state when characters are input up to the input frame 511-5. In other words, “Today is good” is being written. In this way, character input is performed.

When correcting an input character, there are the following three methods for selecting a character to be corrected.
(1) Move the cursor 521 (see FIG. 4).
(2) Tap a character in the sentence display area 52.
(3) Tap the input frame 511 desired to be corrected in the character input area 51.

When the cursor 521 of (1) is moved and corrected, the cursor 521 is moved immediately before the character to be corrected. At this time, when erasing characters, the DEL button 541 (see FIG. 4) may be tapped.
When tapping a character in the sentence display area 52 of (2), the character itself desired to be corrected is tapped. For example, in FIG. 4, when correcting “day” in the sentence display area 52, the letter “day” itself is tapped.
When tapping the input frame desired to be corrected in the character input area 51 of (3), the input frame 511 having the character desired to be corrected is tapped. For example, in FIG. 4, when correcting “day”, the input frame 511-2 is tapped.

  Next, the character correction mode of the handwritten character input device 1 of the present embodiment will be described.

(Character correction mode (I))
The character correction mode (I) of the handwritten character input device 1 will be described.
FIG. 6 is a diagram for explaining the character correction mode (I) of the handwritten character input device 1. In the figure, in the character correction mode (I), the correction target character and the input frame 511 of the character input area 51 are related and emphasized. That is, the background color of the correction target character and the color of the input frame are the same color. In FIG. 6, when correcting the character “Month”, the background color 60 of “Month” in the sentence display area 52 and the color of the input frame 511-2 in the character input area 51 are changed to orange.

  Thus, in the character correction mode (I), the correction target character and the input frame 511 are related and emphasized. By doing so, it is possible to clearly recognize which input frame 511 of the six input frames 511 should be used to input a character, and improve the efficiency of character input. In addition, by displaying in association with the highlighting of the correction target character, it is easy to identify which character is being corrected, and it is easy to recognize.

(Character correction mode (II))
The character correction mode (II) of the handwritten character input device 1 will be described.
FIG. 7 is a diagram for explaining the character correction mode (II) of the handwritten character input device 1. In the figure, the character correction mode (II) is a modification of the character correction mode (I) described above, and the correction target character and the input frame 511 are associated by the connecting line 61. By doing so, it is possible to more clearly recognize which input frame 511 of the six input frames 511 should be used to input a character, and further improve the efficiency of character input. In addition, by displaying the correction target character in association with the highlighted display, it is very easy to identify which character is being corrected, and it is easy to recognize.

(Character correction mode (III))
The character correction mode (III) of the handwritten character input device 1 will be described.
FIG. 8 is a diagram for explaining the character correction mode (III) of the handwritten character input device 1. In the figure, in the character correction mode (III), in addition to the character correction mode (I) described above, the display in the input frame 511 is erased. That is, when correcting the character of “month”, the background color 60 of “month” in the sentence display area 52 and the color of the input frame 511-2 of the character input area 51 are set to orange, and the character in the input frame 511-2 Erase the display (display of “Month”).

  In this way, in the character correction mode (III), the correction target character and the input frame 511 are related and emphasized, and the display in the input frame 511 is deleted. By doing in this way, it becomes easy to let a user notice that it is in a state where handwritten input is possible. In other words, if the font display in the input frame 511 remains, it is difficult for the user to determine whether or not handwriting input is possible. Therefore, if the font display disappears, the user can easily perform handwriting input. Can be recognized.

(Character correction mode (IV))
The character correction mode (IV) of the handwritten character input device 1 will be described.
FIG. 9 is a diagram for explaining the character correction mode (IV) of the handwritten character input device 1. In the figure, in the character correction mode (IV), the highlighted display is ended by tapping an area other than the highlighted input frame 511-2. That is, when an area other than the input frame 511-2 is tapped (in FIG. 9, the inside of the input frame 511-4 is tapped), the highlighted display of the input frame 511-2 ends.

  As described above, in the character correction mode (IV), the highlighted display is ended by tapping the area other than the highlighted input frame 511-2. In this way, the correction mode can be easily terminated and canceled without any erroneous operation. The target tap area is an area other than the highlight frame, and has a large area and is easily tapped.

(Character correction mode (V))
The character correction mode (V) of the handwritten character input device 1 will be described.
FIG. 10 is a diagram for explaining the character correction mode (V) of the handwritten character input device 1. In the figure, in the character correction mode (V), a region other than the input frame 511-2 is tapped without inputting handwritten characters in the highlighted input frame 511-2 in the process of the character correction mode (IV). When the highlighting is finished, the original display content is restored. That is, when an area other than the highlighted input frame 511-2 is tapped, the highlighted display is terminated and the original display content ("month") is restored. By returning to the original state in this way, the user can easily recognize that the correction mode has been canceled, and the efficiency of character input is improved.

(Character correction mode (VI))
The character correction mode (VI) of the handwritten character input device 1 will be described.
FIG. 11 is a diagram for explaining the character correction mode (VI) of the handwritten character input device 1. In the figure, in the character correction mode (VI), when a handwritten character is input in an input frame 511-4 other than the highlighted input frame 511-2, a character is added to the end of the sentence. That is, a situation where the correction is canceled once occurs, and both can be added to the end of the sentence. As described above, since the character addition to the end of the sentence can be executed using another input frame, the end of the correction mode and the start of the addition of the end-of-sentence character can be performed at a time, and the efficiency of character input is improved.

Next, the operation of the handwritten character input device 1 according to the present embodiment will be described.
FIG.12 and FIG.13 is a flowchart for demonstrating operation | movement of the handwritten character input device 1 of this Embodiment. It is assumed that the current input frame 511 is An and the previous input frame 511 is Ap. 12 and 13, first, as the initialization process, the processes of steps S1 to S3 are performed. That is, the current input frame An is set to a state without input (step S1), and the previous input frame Ap is set to a state without input (step S2). Then, all input frames are set to an uninput state (step S3).

  After all the input frames are in the non-input state, the input coordinate acquisition unit 31 acquires the input coordinates output from the input unit 2 (step S4). That is, the handwriting by the user's handwritten character input is acquired as input coordinates. The input coordinates acquired by the input coordinate acquisition unit 31 are stored in the input coordinate storage unit 32. Next, it is determined whether there is an input frame corresponding to the input coordinate position (step S5). When it is determined that there is no input frame corresponding to the input coordinate position (when “No” is determined in step S5), the process returns to step S4, and the process of step S4 is repeated. On the other hand, when it is determined that there is an input frame corresponding to the input coordinate position (when “Yes” is determined in step S5), the input area corresponding to the input coordinate position is a storage area corresponding to the current input frame An. (Step S6).

  After the input frame corresponding to the input coordinate position is stored in the storage area corresponding to the current input frame An, the state of the current input frame An is determined (step S7). In this determination, when the character input to the input frame is not input or is being input, the current state of the input frame An is set to input (step S8). On the other hand, when the character input to the input frame is being corrected, the current state of the input frame An is set to be corrected (step S9). If the character input to the input frame has been confirmed (that is, in a fontized state), the current state of the input frame An is set during correction (step S10).

  If it is determined in step S7 that character input to the input frame has not been input, is being input, or is being corrected, the handwriting display unit 33 displays handwriting of handwritten characters in the current input frame An (step S11). Next, the handwritten character recognition unit 35 recognizes a character from the handwriting of the handwritten character (step S12). After the character recognition is performed by the handwritten character recognition unit 35, the sentence display unit 38 displays the character recognized by the handwritten character recognition unit 35 in the current input frame An of the sentence display area 52 of the display unit 5. (Step S13).

  On the other hand, if it is determined in step S7 that character input to the input frame has been confirmed, the character correction operation determination unit 40 sets the current state of the input frame An to being corrected (step S10). Next, the input frame display changing unit 41 changes the frame boundary color of the current input frame An in the character input area 51 of the display unit 5 (for example, changes it to orange) (step S14). Next, the correction target character display change unit 42 changes the background color of the correction target character in the sentence display area 52 of the display unit 5 (for example, changes the color to orange) (step S15). After the frame boundary color of the current input frame An in the character input area 51 of the display unit 5 and the background color of the correction target character in the sentence display area 52 of the display unit 5 are changed, the recognized character font display unit 37 The font display in the current input frame An is deleted (step S16). For example, the character “month” is deleted.

  After any of the processes of step S13 and step S16 is performed, it is determined whether the previous input frame Ap is not in the no-input state and the current input frame An is different from the previous input frame Ap (step S17). ). That is, it is determined whether the input frame touched last time is different from the input frame touched this time. If it is determined in step S17 that the input frame touched last time and the input frame touched this time are the same input frame, the state of the current input frame An is set in the previous input frame Ap (step S23). Return. On the other hand, if the input frame touched last time is different from the input frame touched this time in the determination in step S17, the state of the previous input frame Ap is determined (step S18). In this determination, when the state of the previous input frame Ap is not input or has been confirmed, the current input frame An is set in the previous input frame Ap in step S23 (step S23), and the process returns to step S4. On the other hand, when the state of the previous input frame Ap is being input, the recognized character font display unit 37 erases the handwriting display in the previous input frame Ap (step S19), and then in the previous input frame Ap. The recognized characters are displayed in font (step S21). That is, the handwriting display is converted into a font. Then, the state of the previous input frame Ap is set to confirmed (step S22). Next, the state of the current input frame An is set in the previous input frame Ap (step S23), and the process returns to step S4.

  If it is determined in step S18 that the state of the previous input frame Ap is being corrected, the input frame display changing unit 41 restores the frame border color of the input frame Ap (step S20). Next, the correction target character display changing unit 42 restores the background color 60 of the correction target character (step S24). After the frame boundary color of the input frame Ap and the background color 60 of the correction target character are restored, it is determined whether or not handwriting input has been made in the input frame Ap (step S25). If there is a handwriting input in the input frame Ap (if “Yes” is determined in the determination in step S25), the process proceeds to step S19, and the handwriting display in the input frame Ap is erased. On the other hand, when there is no handwriting input in the input frame Ap (when it is determined as “No” in the determination in step S25), the recognized character font display unit 37 displays the original recognized character in the input frame Ap as a font ( Step S26). After the original recognized character is displayed in font in the input frame Ap, the process proceeds to step S22, and the state of the previous input frame Ap is set to confirmed. After finishing the process of step S23, it returns to step S4. And the process of step S4-step S23 is repeated.

  Thus, according to the handwritten character input device 1 according to the present embodiment, the sentence display area 52 capable of displaying a plurality of characters and the character input area 51 including the six input frames 511-1 to 511-6 are provided.
