  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing an outline of a configuration of a character input device 20 according to an embodiment of the present invention.

  The character input device 20 of the present embodiment is a touch panel type in which an LCD module 40 for displaying various menu screens, texts being created, and the like and a touch panel module 42 for inputting handwritten characters by a pen P are combined. It is configured as a liquid crystal display. Note that a power button 22 for starting the character input device 20 and a memory card slot 44 into which the memory card MC can be inserted are provided on the side portion of the character input device 20.

  The touch panel module 42 is a coordinate input device that inputs the coordinates of the point where the pen P is touched on the touch screen. In this embodiment, multi-point detection for detecting contact of two or more points and gesture operation detection are possible. Adopts a simple projected capacitance method. Of course, the method of the touch panel module 42 is not limited to the capacitance method, and various methods such as a resistance film method and an electromagnetic induction method can be adopted. In addition, although the following demonstrates the case where the character string input by handwriting using the pen P is recognized, all the aspects which can input a handwritten character, such as the aspect input by handwriting with a human fingertip, are included.

  As shown in FIG. 1, the character input device 20 controls input of the main controller 30 that controls the entire device, the LCD controller 41 that controls display of the LCD module 40, and the touch panel module 42. A touch panel controller 43 and a memory card controller 45 that controls reading and writing of data with respect to the memory card MC are provided, and these are electrically connected to each other via a bus 48.

  The main controller 30 is configured as a microprocessor centered on the CPU 31, and various processing programs such as a program for recognizing handwritten characters and editing sentences, character fonts, a dictionary, and an input mode that can be used (handwriting). ROM 32 for storing gesture operations and operation procedures for each character input mode and edit mode), a RAM 33 for use as a work area of the CPU 31 and for storing sentences being created, and a flash memory for storing created sentences 34 and an interface 35 (I / F) for inputting an activation signal from the power button 22. The main controller 30 inputs coordinate signals from the touch panel controller 43 and outputs control signals to the LCD controller 41. The main controller 30 also reads and writes text files via the memory card controller 45 with respect to the memory card MC.

  Next, the operation of the character input device 20 of the present embodiment configured as described above will be described. FIG. 2 is an explanatory diagram illustrating an example of the handwritten character input screen 50. The handwritten character input screen 50 is called when handwritten character input, which is one of various menus on a menu screen (not shown), is selected. The title and current time of the text being created, the built-in battery Title display area 52 for displaying remaining capacity, input area 54 for inputting handwritten characters by operating the pen P and performing various editing operations on recognized character strings, and result display area for displaying fixed character strings 56 is displayed.

  As shown in FIG. 2, various instruction button frames 58 for performing various instructions related to handwritten character input are displayed on the right side of the input area 54. The various instruction button frames 58 can be operated by touching (tapping) the tip of the pen P within the button frame. The handwritten input character string is recognized, and the recognized character string is input as it is. A “recognize and convert” button frame displayed on the input area 54, or a “recognize and convert” button frame that recognizes a handwritten character string and converts it into a kana-kanji mixed character string and displays the converted character string in the input area 54 “Delete one character” button frame for deleting only one character after the recognized character string or the converted character string displayed in the input area 54, the recognized character string or the converted character string displayed in the input area 54 A “rewrite” button frame for erasing all characters in the character string and a “confirm” button frame for confirming the recognized character string and the converted character string displayed in the input area 54 and displaying them in the result display area 56 are prepared. ing. In addition, a recognition mode selection button frame 60 is also provided at the top of the input area 54 for selecting whether to recognize Japanese characters or alphabets when recognizing characters.

  The result display area 56 is an area for newly displaying the recognized character string and the converted character string displayed in the input area 54 from the cursor position by tapping the “confirm” button frame. Displays various editing button frames 62 for editing the displayed text. As the various editing button frames 62, a blank button frame, a backward button frame, a line feed button frame, a tab button frame, and the like are prepared.

  3-5 is explanatory drawing which shows a mode that a sentence is produced by handwritten character input. In order to create a sentence by inputting handwritten characters, first, handwritten characters are input to the input area 54 using the pen P (see FIG. 3). When a handwritten character is input, the “recognize as it is” button frame or the “recognize and convert” button frame is tapped to recognize the handwritten character. When the “recognize and convert” button frame is tapped, the handwritten input character string is recognized, the recognized character string is converted to kana / kanji, and the converted character string is displayed in the input area 54 (FIG. 4). reference). Then, when the “OK” button frame is tapped, the converted character string is displayed as a sentence in the result display area 56 (see FIG. 5).

  Next, recognition of handwritten character strings and kana-kanji conversion will be described in more detail. FIG. 6 is a flowchart illustrating an example of character recognition conversion processing executed by the main controller 30. This process is executed when the handwritten character input screen 50 is activated.

  When the character recognition conversion process is executed, the CPU 31 of the main controller 30 first inputs a handwritten character (step S100) and waits for an operation for instructing character recognition (step S110). Here, the input of the handwritten character is performed by acquiring the coordinates of the point touched by the pen P and storing the set of coordinates as the stroke of the pen P. Here, as described above, the operation for instructing the character recognition can be performed by tapping the “recognize as it is” button frame or by tapping the “recognize and convert” button frame. "Conversion and conversion" can also be performed by a gesture operation. Whether or not the character recognition is instructed by the gesture operation is determined by storing the gesture operation (stroke) corresponding to “recognize and convert” in the ROM 32 in advance, and inputting the gesture operation. Can be performed by comparing the gesture operation (stroke) stored in the pattern matching by pattern matching.

  When character recognition is instructed, the stroke of the pen P is recognized as a character by pattern matching with a dictionary for character recognition stored in the ROM 32 in accordance with a known recognition algorithm (step S120), and the recognized character string is kana. Conversion into a kanji mixed character string (kana-kanji conversion) (step S130). Here, the kana-kanji conversion does not form the gist of the present invention, so a detailed description thereof is omitted. For example, a word stored in the ROM 32 is searched using a word search dictionary from reading of a recognized character string. Then, a phrase that can be established as a grammar is extracted based on the searched word and the grammatical information stored in the ROM 32, and the kanji notation of the extracted phrase is referred to the kana-kanji conversion dictionary stored in the ROM 32. However, it can be done by deciding. If “recognize as it is” is instructed, kana-kanji conversion is not necessary, so the process of step S130 is skipped.

  When the character string is recognized or converted in this way, the recognized or converted character string is displayed in the input area 54 (step S140), and an operation for instructing editing (including confirmation) is waited for (step S140). S150). The operation for instructing editing can be performed by tapping the “delete one character” button frame, the “rewrite” button frame or the “confirm” button frame of the various instruction button frames 58, but by various gesture operations. Can also be done. As editing items that can be performed by a gesture operation, in this embodiment, “insert” for inserting a new character between specified characters in a character string, or replacing a specified character in a character string with a new character. “Overwrite insertion” and “delete” for deleting a specified character in a character string are provided. In addition to this, for example, “replacement” in which two designated characters in the character string are replaced so that “Ia” is “ai”, or “yo” is “yo” in the character string, for example. "Upper case conversion" that converts the specified character from lower case to upper case, for example, "Lower case conversion" that converts the specified character in the string from upper case to lower case so that "yo" is "yo", for example "ki" "Partial append" to add to the specified character in the string and convert it to another character, for example, "gi" to "ki" of the specified character in the string “Partial deletion” that deletes a part and converts it to another character, for example, “union” that re-recognizes a character recognized as a plurality of characters such as “wood” as “forest”, For example, “Hayashi” is recognized as “Kiki” as one character. Re aware of as a multiple of the character "separation", editing items such as "confirmation" to confirm the recognized character string is also available. It is determined whether or not an editing instruction has been given by a gesture operation. Gesture operations (strokes) corresponding to various editing items are stored in the ROM 32 in advance, and when a gesture operation is input, the input strokes and the gestures stored in the ROM 32 are stored. This can be done by comparing the operation (stroke) with pattern matching.

  If it is determined that an operation for instructing editing has been performed, it is determined whether the operation is a gesture operation (step S160). If it is determined that the operation is a gesture operation, the used gesture operation (edit item) is stored in the RAM 33 as a use history. If it is stored (step S180) and it is determined that the operation is not a gesture operation, the process of step S180 is skipped. If the operation for instructing editing is not a “confirm” operation (step S190), the editing process corresponding to the instructed editing item is executed (step S200), and the process returns to step S150 to instruct editing. If the operation is a “confirm” operation (step S190), the character string displayed in the input area 54 is displayed in the result area 56 (step S210), and this process ends.

  Next, a process for guiding the operation procedure of the gesture operation will be described. FIG. 7 is a flowchart illustrating an example of the gesture operation guidance process. This routine is repeatedly executed at predetermined time intervals while the handwritten character input screen 50 is activated.

  In the gesture operation guidance process, first, a process for determining the current input mode is performed (step S300). In this embodiment, in this embodiment, the current input mode is determined as the handwriting input mode until it is determined that the character recognition is instructed in step S110 after the handwritten character input is started in step S100 of the character recognition conversion process. The current input mode is determined to be the edit mode until it is determined in step S190 that the “confirm” operation has been performed after the conversion result is displayed in step S140 of the character recognition conversion process. If it is determined that the current input mode is neither the handwritten character input mode nor the edit mode (steps S310 and S320), this process is terminated.

  When it is determined that the current input mode is the handwritten character input mode (step S310), the gesture guidance indicating the operation procedure of the gesture operation for the handwritten character input mode is read from the ROM 32 and displayed in the guidance display area 64. (Step S330), this process is terminated. FIG. 8 shows a gesture operation of “recognize and convert”, and FIG. 9 shows an example of gesture guidance in the handwriting input mode. In the handwritten character input mode, as shown in FIG. 8, a character string is input by handwriting into the input area 54, and "" "" is input at the end of the character string to indicate "recognize and convert". can do. In the present embodiment, the guidance display area 64 is provided in the input area 54, and handwritten characters can be input to the guidance display area 64. The gesture guidance in the handwritten character input mode is displayed as an animation, and as shown in FIG. 9, a state where a handwritten character “AI” is input and “” ”is input by a gesture operation at the end of“ AI ”. This is performed by sequentially switching between the state in which the character recognition and the result of kana-kanji conversion are displayed as “go”.

  On the other hand, when it is determined that the current input mode is not the handwritten character input mode but the edit mode (step S320), the use history of the gesture operation related to the edit instruction stored in the RAM 33 in step S180 of the character recognition conversion process. (Step S340), the editing items are sorted in descending order of usage frequency based on the read usage history (step S350), and gesture guidance indicating the operation procedure of the gesture operation of various editing items is read from the ROM 32 and the usage frequency is A predetermined number (three in the present embodiment) in order from the highest edit item is displayed in the guidance display area 64 (step S360), and this process is terminated. FIG. 10 shows the state of the gesture operation of “Insert”, FIG. 11 shows the state of gesture operation of “Insert Overwrite”, and FIG. 12 shows the state of gesture operation of “Delete”.

  In “Insert”, as shown in FIG. 10, when “|” is input by handwriting between characters to be inserted, a space for one character is formed therefrom, and a new handwritten character is input in the blank portion. It will be ready. In this state, when a handwritten character is input with the pen P and recognition is instructed, the character input by handwriting is recognized, and the recognized new character is inserted into the input area 54.

  In “overwrite insertion”, as shown in FIG. 11, when a character to be overwritten is surrounded by “○” by handwriting, the character is deleted, and a new handwritten character is added to a blank portion after the character is deleted. Is ready for input. In this state, when a handwritten character is input with the pen P and recognition is instructed, the character input by handwriting is recognized, and the recognized new character is overwritten in the input area 54.

  In “delete”, as shown in FIG. 12, when a character “−” is input by hand over the character to be deleted, the character is deleted, and the input area is filled with the erased blank portion. 54 character strings are displayed again.

  The gesture guidance in the edit mode is displayed by animation. FIG. 13 shows an example of an animation display of gesture guidance in the edit mode. FIG. 13A shows an animation display of the “insertion” gesture guidance, FIG. 13B shows an animation display of the “insertion” gesture guidance, and FIG. 13C shows “deletion”. An animation display of gesture guidance is shown. As shown in FIG. 13A, the animation display of the “Insert” operation procedure shows that a character string recognized as “Au” is displayed, and “|” is a gesture operation between “Au” characters. , A state where a space is formed between the characters “Au”, a state where “I” is input by handwriting in the space between the characters “Au”, and a result that “Ayu” is recognized This is performed by sequentially switching the display of the. In addition, as shown in FIG. 13B, the animation display of the “overwrite insert” operation procedure shows that the character string recognized as “Ah” is displayed, and “A” in the middle is “ "The gesture operation surrounded by" is entered, the middle "A" is erased and a space is formed, "I" is entered by handwriting in the space between the characters "Au", " This is done by sequentially switching the display of the result recognized as “that”. Furthermore, as shown in FIG. 13C, the animation display of the “delete” operation procedure shows that the recognized character string “A” is displayed, and “-” in the middle “I” is a gesture. It is performed by sequentially switching between the state of input by operation, the state where the middle “I” is erased and a blank is formed, and the state where the result recognized as “Yes” is displayed after being filled with blanks. .

  FIG. 14 is an explanatory diagram showing how the display of gesture guidance is switched in the edit mode. In the edit mode, as described above, the gesture guidance is displayed in the guidance display area 64 with a predetermined number as an upper limit. For this reason, the operation procedure of the gesture operation in the edit item that cannot be displayed in the guidance display area 64 can be referred to by switching the display using the right movement button frame 64a and the left movement button frame 64b. Specifically, as shown in FIG. 14, as a gesture that can be used now, when the guidance of “insert”, “insert overwrite”, and “delete” is displayed, when the right move button 64a is tapped once, It is possible to switch to the guidance display of “replacement”, “upper case conversion”, and “lower case conversion”. When the right movement button 64a is tapped once from this state, the guidance display of “partial addition”, “partial deletion”, and “merging” is switched, and further, when the right movement button 64a is tapped once from this state, “separation” "And" Confirm "guidance display. When the left move button 64b is tapped, the previous guidance display is restored.

  Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The touch panel type liquid crystal display comprising the LCD module 40 and the touch panel module 42 of this embodiment corresponds to the “display means” of the present invention, the ROM 32 corresponds to the “storage means”, and the steps of the gesture operation guidance process of FIG. The main controller 30 that executes the process of S300 corresponds to “input mode determination means”, and the main controller 30 that executes the processes of steps S310 to S360 of the gesture operation guidance process corresponds to “operation procedure display means”. The main controller 30 that executes the processes of steps S110 and S150 of the character recognition conversion process corresponds to “operation accepting means”, and the main controller 30 that executes the processes of steps S200 and S210 of the character recognition conversion process performs the “operation corresponding process”. Equivalent to `` execution means '' .

  According to the character input device 20 of the present embodiment described above, a handwritten character is input via the touch panel module 42 (handwritten character input mode), or a recognized character string or a converted character string is edited. In the device that can perform (edit mode), the current input mode is determined, and the operation procedure of the gesture operation that can be used in the current input mode is displayed in the guidance display area 64 in the input area 54 as gesture guidance. Therefore, the user can execute various processes using the gesture operation without having to remember a number of gesture operation procedures and input modes that can be used. As a result, the user can be encouraged to use the gesture operation when inputting handwritten characters, and the convenience can be further improved. In addition, since the operation procedure of the gesture operation is displayed by animation display, the user can easily understand the operation procedure of the gesture operation. Furthermore, since the operation procedure of the gesture operation in the edit mode is displayed up to a predetermined number in the order of frequency of use, the user can immediately refer to the operation procedure of the gesture operation with the high frequency of use.
