Description

文字入力装置、文字入力方法、および文字入力プログラムCharacter input device, character input method, and character input program
 本発明は、文字入力装置、文字入力方法、および文字入力プログラムに関する。特に、筆跡から文字を認識する文字入力装置等に関する。 The present invention relates to a character input device, a character input method, and a character input program. In particular, the present invention relates to a character input device that recognizes characters from handwriting.
 従来、手書き文字を入力可能な文字入力装置が知られている。例えば、「明日の12時に、」という文字列をスタイラスペン等により手書きで入力する場合、1文字の文字記入領域に「12」の筆跡が記入されると、文字入力装置は、「12」の筆跡から認識結果として「1」、「2」の文字コードを取得する。 Conventionally, a character input device capable of inputting handwritten characters is known. For example, when the character string “at 12:00 tomorrow” is input by handwriting with a stylus pen or the like, when the handwriting of “12” is entered in the character entry area of one character, the character input device is “12”. Character codes “1” and “2” are acquired from the handwriting as recognition results.
 この種の先行技術として、1つの文字領域に複数の数字を入力しても認識することができる文字認識装置が知られている(特許文献1参照)。 As a prior art of this type, there is known a character recognition device that can recognize even if a plurality of numbers are input in one character area (see Patent Document 1).
日本国特開平6-236454号公報Japanese Unexamined Patent Publication No. 6-236454
 しかしながら、従来の文字入力装置では、例えば入力された「明日の12時に、」という文字列に対し、右からフォーカスあるいはカーソルを移動させる場合、「時」→「2」→「1」→「の」という順で移動が行われる。すなわち、ユーザが入力した文字「12」に対し、フォーカスが当たる文字は「1」あるいは「2」となり、入力文字との不一致が発生する。このため、ユーザには違和感が生じていた。このことは、フォーカスやカーソルの移動に限らず、1文字を削除する場合や書き直す場合でも同様であった。 However, in the conventional character input device, for example, when the focus or cursor is moved from the right to the input character string “at 12:00 tomorrow”, “hour” → “2” → “1” → “ Are moved in this order. That is, for the character “12” input by the user, the focused character is “1” or “2”, and a mismatch with the input character occurs. For this reason, the user feels uncomfortable. This is not limited to focus and cursor movement, and is the same when deleting or rewriting one character.
 このように、従来では、認識された文字を編集時や表示時にどのように扱うかは考慮されていなかった。 Thus, conventionally, it has not been considered how to handle recognized characters when editing or displaying.
 本発明は、複数の文字で構成される文字列が入力された場合であっても、入力時と表示時又は編集時とで、違和感が生じることなく操作することができる文字入力装置、文字入力方法、および文字入力プログラムを提供することを目的とする。 The present invention provides a character input device and a character input that can be operated without causing a sense of incongruity between input and display or editing even when a character string composed of a plurality of characters is input. It is an object to provide a method and a character input program.
 本発明の文字入力装置は、所定の領域に筆跡を入力する筆跡入力部と、同一の領域に入力された筆跡から、複数の文字で構成された文字列を認識する文字認識部と、前記文字認識部により認識された文字列を表示する表示部と、前記文字認識部により認識された文字列の文字数に応じて、前記文字列の前記表示部による表示時又は編集時の制御を行う制御部と、を備える。 The character input device of the present invention includes a handwriting input unit that inputs handwriting in a predetermined region, a character recognition unit that recognizes a character string composed of a plurality of characters from the handwriting input in the same region, and the character A display unit that displays a character string recognized by the recognition unit, and a control unit that controls when the character string is displayed or edited by the display unit according to the number of characters of the character string recognized by the character recognition unit And comprising.
 この構成によれば、認識された文字列の文字数に応じて、文字列の表示時又は編集時の制御を行うので、複数の文字で構成される文字列が入力された場合も、入力時と表示時又は編集時とで文字数が一致し、違和感が生じることなく操作することができる。 According to this configuration, since control is performed at the time of displaying or editing a character string according to the number of characters of the recognized character string, even when a character string composed of a plurality of characters is input, The number of characters matches during display or editing, and operation can be performed without causing a sense of incongruity.
 本発明の文字入力方法は、所定の領域に筆跡を入力するステップと、同一の領域に入力された筆跡から、複数の文字で構成された文字列を認識するステップと、前記認識された文字列を表示部により表示する表示ステップと、前記認識された文字列の文字数に応じて、前記文字列の表示時又は編集時の制御を行うステップと、を有する。 The character input method of the present invention includes a step of inputting a handwriting in a predetermined region, a step of recognizing a character string composed of a plurality of characters from a handwriting input in the same region, and the recognized character string A display step for displaying the character string, and a step for performing control during display or editing of the character string in accordance with the number of characters of the recognized character string.
 この方法によれば、認識された文字列の文字数に応じて、文字列の表示時又は編集時の制御を行うので、複数の文字で構成される文字列が入力された場合も、入力時と表示時又は編集時とで文字数が一致し、違和感が生じることなく操作することができる。 According to this method, control is performed at the time of displaying or editing a character string according to the number of characters in the recognized character string, so that even when a character string composed of a plurality of characters is input, The number of characters matches during display or editing, and operation can be performed without causing a sense of incongruity.
 本発明の文字入力プログラムは、上記文字入力方法の各ステップをコンピュータに実行させるためのプログラムである。 The character input program of the present invention is a program for causing a computer to execute each step of the character input method.
 このプログラムによれば、認識された文字列の文字数に応じて、文字列の表示時又は編集時の制御を行うので、複数の文字で構成される文字列が入力された場合も、入力時と表示時又は編集時とで文字数が一致し、違和感が生じることなく操作することができる。 According to this program, control is performed at the time of displaying or editing a character string according to the number of characters in the recognized character string, so even when a character string composed of a plurality of characters is input, The number of characters matches during display or editing, and operation can be performed without causing a sense of incongruity.

 本発明の実施形態における文字入力装置、文字入力方法、および文字入力プログラムについて、図面を用いて以下に説明する。本実施形態の文字入力装置は、手書き入力機能を有する電子機器に適用される。 A character input device, a character input method, and a character input program according to an embodiment of the present invention will be described below with reference to the drawings. The character input device of this embodiment is applied to an electronic device having a handwriting input function.
(第1の実施形態)
 図1は本発明の第1の実施形態おける文字入力装置1の構成例を示すブロック図である。文字入力装置1は、筆跡入力部11、文字認識部12、制御部13、文字表示部14、およびユーザ操作部15を有して構成される。
(First embodiment)
FIG. 1 is a block diagram showing a configuration example of a character input device 1 according to the first embodiment of the present invention. The character input device 1 includes a handwriting input unit 11, a character recognition unit 12, a control unit 13, a character display unit 14, and a user operation unit 15.
 筆跡入力部11は、文字表示部14の画面に設けられたタッチパネルからなり、スタイラスペン等を用いて文字記入領域11a(後述する図2参照)に記入されたユーザの筆跡を入力する。なお、タッチパネルは接触式のものでもよいし、押圧式のものでもよい。 The handwriting input unit 11 includes a touch panel provided on the screen of the character display unit 14 and inputs a user's handwriting written in the character entry area 11a (see FIG. 2 described later) using a stylus pen or the like. The touch panel may be a contact type or a press type.
 文字認識部12は、筆跡入力部11により入力された筆跡から文字を認識する。文字認識部12には、筆跡入力部11により入力された“00”~“99”等の筆跡や候補文字群を記憶するメモリ12a、および筆跡に対応する文字コード(例えば、Unicode)が登録されたデータベース12bが設けられている。データベース12bは、複数桁の文字に対応する文字コード(例えば「12」に対応する文字コード)を特殊コードとして保持している。文字認識部12は、文字記入領域11a(所定の領域)に記入された1文字の文字を認識する他、複数桁の数字等からなる文字列も認識し、この複数桁の数字(文字列)に対応する特殊コードをデータベース12bから取得してメモリ12aに記憶する。 The character recognition unit 12 recognizes characters from the handwriting input by the handwriting input unit 11. In the character recognizing unit 12, a memory 12a for storing handwriting such as “00” to “99” and a candidate character group input by the handwriting input unit 11, and a character code (for example, Unicode) corresponding to the handwriting are registered. A database 12b is provided. The database 12b holds a character code corresponding to a multi-digit character (for example, a character code corresponding to “12”) as a special code. The character recognition unit 12 recognizes a single character entered in the character entry area 11a (predetermined area) and also recognizes a character string made up of a plurality of digits and the like. Is obtained from the database 12b and stored in the memory 12a.
 さらに、文字認識部12は、認識された文字の文字コードを制御部13に通知する。また、認識された文字が複数桁の数字である場合、複数桁の数字に対応する特殊コードから、個々の数字の文字コードを取得し、制御部13に通知する。なお、ここでは、文字列として、複数桁の数字を挙げているが、後述するように、複数のアルファベットやひらがなで文字列は構成されてもよい。 Further, the character recognition unit 12 notifies the control unit 13 of the character code of the recognized character. When the recognized character is a multi-digit number, the character code of each number is acquired from the special code corresponding to the multi-digit number and notified to the control unit 13. Here, although a multi-digit number is cited as the character string, the character string may be composed of a plurality of alphabets or hiragana as will be described later.
 制御部13は、文字認識部12で認識され、メモリ12aに記憶された文字コードを受け取る。そして、制御部13は、この文字コードをもとに、ユーザ操作部15のイベントに応じて、カーソル位置やフォーカス位置を制御し、認識候補の表示や書き直し等を行う。すなわち、制御部13は、文字認識部12により認識された文字列の文字数に応じて、文字列の文字表示部14による表示時又は編集時の制御を行う。 The control unit 13 receives the character code recognized by the character recognition unit 12 and stored in the memory 12a. Then, the control unit 13 controls the cursor position and the focus position in accordance with the event of the user operation unit 15 based on the character code, and displays or rewrites the recognition candidates. That is, the control unit 13 performs control during display or editing of the character string by the character display unit 14 according to the number of characters of the character string recognized by the character recognition unit 12.
 また、制御部13には、メモリ13a、後述するフォーカスやカーソルの移動を制御するフォーカス/カーソル位置制御部13b、および文字認識部12を制御する文字認識制御部13cが設けられている。 Further, the control unit 13 is provided with a memory 13a, a focus / cursor position control unit 13b that controls the movement of the focus and cursor described later, and a character recognition control unit 13c that controls the character recognition unit 12.
 文字記入領域11aに複数桁の数字が記入された場合、制御部13は、メモリ13aに “1”、“2”など個々の数字の筆跡を記憶する。さらに、制御部13は、文字認識部12で認識された複数桁の数字に対応する、個々の数字の文字コードを文字認識部12から受け取り、メモリ13aに記憶する。 When a plurality of digits are entered in the character entry area 11a, the control unit 13 stores handwriting of individual numbers such as “1” and “2” in the memory 13a. Further, the control unit 13 receives character codes of individual numbers corresponding to the multi-digit numbers recognized by the character recognition unit 12 from the character recognition unit 12, and stores them in the memory 13a.
 文字表示部14は、LCD(Liquid Crystal Display)等の表示装置であり、制御部13の指示に従って、画面に文字等を表示する。文字表示部14は、例えば、文字認識部12により認識された文字列を表示する。 The character display unit 14 is a display device such as an LCD (Liquid Crystal Display), and displays characters and the like on the screen according to instructions from the control unit 13. The character display part 14 displays the character string recognized by the character recognition part 12, for example.
 ユーザ操作部15は、各種キーからなり、キー操作によるカーソル移動などのイベントを入力し、イベントの入力があったことを制御部13に通知する。 The user operation unit 15 includes various keys, inputs events such as cursor movement by key operation, and notifies the control unit 13 that an event has been input.
 なお、制御部13および文字認識部12の機能は、専用のハードウェア回路で実現されてもよいし、CPUによるソフトウェア制御により実現されてもよい。また、制御部13には、USB等の入出力インタフェース(図示せず)が接続され、外部機器とデータの送受信を行うようにしてもよい。 The functions of the control unit 13 and the character recognition unit 12 may be realized by a dedicated hardware circuit, or may be realized by software control by the CPU. Further, an input / output interface (not shown) such as a USB may be connected to the control unit 13 so as to transmit / receive data to / from an external device.
 図2は文字入力装置1の外観例を示す図である。
 文字入力装置1の例えば筐体前面には、文字表示部14、筆跡入力部11、およびユーザ操作部15が設けられている。文字表示部14には、入力された文字列が表示される。筆跡入力部11には、スタイラスペン等により手書き入力可能な文字記入領域11aが設けられている。なお、文字記入領域11aには、前述したように、複数桁の数字などを記入することも可能である。ここでは、手書きで「12」が記入されている。
FIG. 2 is a diagram showing an example of the appearance of the character input device 1.
For example, a character display unit 14, a handwriting input unit 11, and a user operation unit 15 are provided on the front surface of the character input device 1. The character display unit 14 displays the input character string. The handwriting input unit 11 is provided with a character entry area 11a that can be handwritten with a stylus pen or the like. In the character entry area 11a, as described above, it is possible to enter a plurality of digits. Here, “12” is entered by handwriting.
 ユーザ操作部15は、削除キー15a、変換キー15b、訂正キー15c、左キー15d、右キー15e、および確定キー15fなどを有する。なお、ユーザ操作部15は、これら各種キーが表示された部分の画面を切り替えることにより、全角/半角キーなどその他のキーも有してもよい。 The user operation unit 15 includes a delete key 15a, a conversion key 15b, a correction key 15c, a left key 15d, a right key 15e, a confirmation key 15f, and the like. Note that the user operation unit 15 may have other keys such as a full-width / half-width key by switching the screen of the portion on which these various keys are displayed.
 次に、文字入力装置1の動作について説明する。 Next, the operation of the character input device 1 will be described.
 始めに、文字入力装置1によるカーソルおよびフォーカスの移動について説明する。図3は文字入力装置1のカーソルおよびフォーカスの移動手順の一例を示すフローチャートである。この動作を行う文字入力プログラムは、文字入力装置1内のROMに格納され、文字入力装置1内のCPUによって実行される。 First, the movement of the cursor and focus by the character input device 1 will be described. FIG. 3 is a flowchart showing an example of a procedure for moving the cursor and focus of the character input device 1. A character input program for performing this operation is stored in the ROM in the character input device 1 and is executed by the CPU in the character input device 1.
 まず、制御部13が、筆跡入力部11により筆跡が入力されたか否かを判別する(ステップS1)。例えば、図2に示すように、文字記入領域11aには、手書きによる複数桁の数字「12」が入力される。筆跡が入力されない場合、文字入力装置1はステップS5の処理に進む。 First, the control unit 13 determines whether or not a handwriting is input by the handwriting input unit 11 (step S1). For example, as shown in FIG. 2, a handwritten multi-digit number “12” is input to the character entry area 11a. If the handwriting is not input, the character input device 1 proceeds to the process of step S5.
 一方、筆跡入力部11により筆跡の入力があると、文字認識部12は、入力された筆跡に対応する文字を認識する(ステップS2)。このとき、文字認識部12は、筆跡の座標パターンを用いてデータベース12bに登録されている文字コードを取得し、メモリ12aに記憶する。なお、認識された筆跡が複数桁の数字を表すものである場合でも通常と同様に、文字認識部12は、複数桁の数字に対応する文字コードも取得する。ただし、複数桁の数字は特殊な文字コードを利用する。 On the other hand, when a handwriting is input by the handwriting input unit 11, the character recognition unit 12 recognizes a character corresponding to the input handwriting (step S2). At this time, the character recognition unit 12 acquires the character code registered in the database 12b using the coordinate pattern of the handwriting and stores it in the memory 12a. Even when the recognized handwriting represents a multi-digit number, the character recognition unit 12 also acquires a character code corresponding to the multi-digit number as usual. However, special character codes are used for multi-digit numbers.
 制御部13は、文字認識部12から認識された文字コードを受け取り、制御部13内のメモリ13aに記憶する(ステップS3)。認識された文字が複数桁の数字(文字列)である場合、この複数桁の数字に対応する個々の数字の文字コードをメモリ13aに記憶する。ここでは、制御部13は、特殊コードであることから、複数桁数字であると判断し、1つの特殊コードから、複数の通常(個々の)文字コードに変換する。つまり、メモリ13aには、個々の数字の文字コードが記憶される。このような動作を繰り返すことで、メモリ13aには、複数の文字が入力された入力文字列が記憶される。 The control unit 13 receives the character code recognized from the character recognition unit 12, and stores it in the memory 13a in the control unit 13 (step S3). When the recognized character is a multi-digit number (character string), the character code of each number corresponding to the multi-digit number is stored in the memory 13a. Here, since it is a special code, the control unit 13 determines that it is a multi-digit number, and converts it from one special code to a plurality of normal (individual) character codes. That is, the character code of each number is stored in the memory 13a. By repeating such an operation, an input character string in which a plurality of characters are input is stored in the memory 13a.
 制御部13は、制御部13内のメモリ13aに記憶された入力文字列に対し、フラグを設定する(ステップS4)。なお、制御部13は、特殊コードであることから複数桁数字であることを判断し、フラグを設定する。 The control unit 13 sets a flag for the input character string stored in the memory 13a in the control unit 13 (step S4). Note that the control unit 13 determines that it is a multi-digit number because it is a special code, and sets a flag.
 図4はメモリ13aに記憶された入力文字列およびフラグの一例を示す図である。ここでは、メモリ13aには、「明日の12時」という入力文字列と、各文字に対応するフラグの値が記憶されている。具体的には、文字「明」、「日」、「の」、「時」のフラグには、値“0”が設定されている。一方、文字「1」、「2」のフラグには、値“0”以外のフラグが立てられ、ここでは値“2”が設定されている。この数値は、入力された文字列の文字数に対応しており、後述するように、フォーカス移動などを行う際の移動量を表す。 FIG. 4 is a diagram showing an example of the input character string and flag stored in the memory 13a. Here, the memory 13a stores an input character string “12 o'clock tomorrow” and a flag value corresponding to each character. Specifically, the value “0” is set in the flags of the characters “Ming”, “Day”, “No”, and “Hour”. On the other hand, flags other than the value “0” are set for the flags of the characters “1” and “2”, and the value “2” is set here. This numerical value corresponds to the number of characters in the input character string, and represents the amount of movement when performing focus movement or the like, as will be described later.
 なお、上記の説明は、「12」を1マス(図2における1つの文字記入領域11a)に記載した場合を想定してフラグの値が“2”となる説明をしたが、各マスに「1」と「2」をそれぞれ記載したときには、フラグの値は“0”となる。 In the above description, “12” is described in one square (one character entry area 11a in FIG. 2) and the flag value is “2”. When “1” and “2” are described, the flag value is “0”.
 また、フラグには、値“3”以上の値が設定されてもよい。例えば、1マスに「123」と3つの数字を記載した場合にはフラグの値は“3”となる。 Further, a value of “3” or more may be set in the flag. For example, when “123” and three numbers are written in one cell, the flag value is “3”.
 文字表示部14は、制御部13の指示に従って、入力された文字を表示する(ステップS5)。 The character display unit 14 displays the input characters in accordance with instructions from the control unit 13 (step S5).
 この後、制御部13は、ユーザ操作部15の各種キーのうち、左キー15dが押下されたか否かを判別する(ステップS6)。左キー15dが押下されない場合、文字入力装置1は、ステップS1の処理に戻る。 Thereafter, the control unit 13 determines whether or not the left key 15d is pressed among the various keys of the user operation unit 15 (step S6). If the left key 15d is not pressed, the character input device 1 returns to the process of step S1.
 一方、左キー15dが押下された場合、制御部13は、メモリ13aに記憶されたフラグの値を判別する(ステップS7)。フラグの値が“0”である場合、制御部13は、文字表示部14に表示された文字列に対し、カーソルを1つ移動させ(ステップS8)、1文字分のフォーカスを当てる(ステップS9)。この後、文字入力装置1は、ステップS5の処理に戻る。 On the other hand, when the left key 15d is pressed, the control unit 13 determines the value of the flag stored in the memory 13a (step S7). When the value of the flag is “0”, the control unit 13 moves the cursor by one to the character string displayed on the character display unit 14 (step S8), and focuses one character (step S9). ). Thereafter, the character input device 1 returns to the process of step S5.
 また、ステップS7でフラグの値が“0”以外、例えば“2”である場合、制御部13は、フラグの値だけカーソルを移動させ(ステップS10)、移動した部分にフォーカスを当てる(ステップS11)。この後、文字入力装置1は、ステップS5の処理に戻る。 If the flag value is other than “0”, for example “2” in step S7, the control unit 13 moves the cursor by the flag value (step S10), and focuses the moved portion (step S11). ). Thereafter, the character input device 1 returns to the process of step S5.
 図5はカーソルおよびフォーカスの移動の一例を示す図である。左キー15dを押下する前、カーソルおよびフォーカスは、文字列「明日の12時に、」のうち、文字「時」の位置にあったが、左キー15dを押下すると、カーソルおよびフォーカスは、複数桁の数字からなる文字列「12」の位置に移動する。さらに、左キー15dを押下すると、カーソルおよびフォーカスは、文字「の」の位置に移動する。なお、ここでは、カーソルは四角の枠で表され、フォーカスはこの枠内の反転表示で表されている。 FIG. 5 shows an example of cursor and focus movement. Before the left key 15d was pressed, the cursor and focus were at the position of the character “hour” in the character string “12 o'clock tomorrow”. It moves to the position of the character string “12” made up of the numbers. Furthermore, when the left key 15d is pressed, the cursor and focus move to the position of the character “NO”. Here, the cursor is represented by a square frame, and the focus is represented by a reverse display in the frame.
 このように、記憶部としてのメモリ13aは、文字認識部12により認識された複数の文字で構成された文字列の各文字に対応させて文字数に基づくフラグを記憶してもよい。制御部13は、メモリ13aに記憶されたフラグに基づいてこの文字列を1つの文字として、この文字列の表示時又は編集時の制御を行ってもよい。これにより、カーソルおよびフォーカスを移動させると、ユーザが文字記入領域11aに記入した複数桁の数字「12」と同じように、文字数の等しい数字「12」にカーソルが移動してフォーカスが当たるので、ユーザに違和感が生じない。 As described above, the memory 13a as the storage unit may store a flag based on the number of characters in correspondence with each character of a character string composed of a plurality of characters recognized by the character recognition unit 12. The control unit 13 may perform control at the time of displaying or editing the character string by setting the character string as one character based on the flag stored in the memory 13a. As a result, when the cursor and focus are moved, the cursor moves to the number “12” having the same number of characters as the multi-digit number “12” entered by the user in the character entry area 11a. The user does not feel uncomfortable.
 また、文字を削除する場合、同様に、削除キー15aを押下することで、カーソルが位置する数字「12」を1つの文字として一度に削除することが可能である。 Similarly, when deleting a character, it is possible to delete the number “12” where the cursor is located as one character at a time by pressing the delete key 15a.
 次に、認識候補の表示および書き直しについて説明する。
 図6は認識候補の表示および書き直し手順の一例を示すフローチャートである。この動作を行う文字入力プログラムは、文字入力装置1内のROMに格納され、文字入力装置1内のCPUによって実行される。
Next, display and rewriting of recognition candidates will be described.
FIG. 6 is a flowchart showing an example of recognition candidate display and rewriting procedures. A character input program for performing this operation is stored in the ROM in the character input device 1 and is executed by the CPU in the character input device 1.
 図3と同様、制御部13は、筆跡入力部11により筆跡が入力されたか否かを判別する(ステップS21)。筆跡が入力されない場合、文字入力装置1はステップS25の処理に進む。 As in FIG. 3, the control unit 13 determines whether or not a handwriting is input by the handwriting input unit 11 (step S21). If the handwriting is not input, the character input device 1 proceeds to the process of step S25.
 一方、筆跡入力部11による筆跡の入力があると、文字認識部12は、入力された筆跡に対応する文字を認識する(ステップS22)。 On the other hand, when a handwriting is input by the handwriting input unit 11, the character recognition unit 12 recognizes a character corresponding to the input handwriting (step S22).
 制御部13は、文字認識部12から認識された文字コードを受け取り、制御部13内のメモリ13aに記憶する(ステップS23)。ここで、複数桁の数字などの文字列が入力された場合の動作は、前述した図3と同様である。 The control unit 13 receives the character code recognized from the character recognition unit 12, and stores it in the memory 13a in the control unit 13 (step S23). Here, the operation when a character string such as a multi-digit number is input is the same as that in FIG.
 制御部13は、制御部13内のメモリ13aに記憶された入力文字列に対し、配列番号を設定する(ステップS24)。ここで、配列番号は、表示あるいは編集時に、認識された文字が配置される位置を表す。配列番号の情報はメモリ13a(記憶部)に記憶される。また、同一の配列番号を持つ複数の文字は1つの文字として扱われる。すなわち、同一の配列番号を持つ文字の数は、入力された文字列の文字数に等しい。 The control unit 13 sets an array element number for the input character string stored in the memory 13a in the control unit 13 (step S24). Here, the array element number represents a position where a recognized character is arranged at the time of display or editing. The array number information is stored in the memory 13a (storage unit). A plurality of characters having the same sequence number are handled as one character. That is, the number of characters having the same sequence number is equal to the number of characters in the input character string.
 図7は配列番号ごとに認識される入力文字と候補文字との対応関係の一例を示す図である。例えば、配列番号(1)では、入力文字「明」の候補文字「明」、「朋」が保持され、配列番号(4)では、入力文字「1」、「2」の候補文字「12」、「72」が保持される。 FIG. 7 is a diagram showing an example of the correspondence between input characters recognized for each sequence number and candidate characters. For example, in the array element number (1), the candidate characters “Akira” and “朋” of the input character “Akira” are held, and in the array element (4), the candidate characters “12” of the input characters “1” and “2” are stored. , “72” is held.
 文字表示部14は、制御部13の指示に従って、入力された文字を表示する(ステップS25)。この後、制御部13は、ユーザによってユーザ操作部15等を介して候補表示操作が行われるまで待つ(ステップS26)。この候補表示操作は、左キー15dや右キー15eの押下によってフォーカス位置a(図7参照)を移動させ、変換キー15bの押下によって筆跡入力部11の位置に候補文字群を表示させ、候補文字にフォーカスを当てる操作である。図8は筆跡入力部11の位置に表示される候補文字群の一例を示す図である。ここでは、文字「12」の候補文字として、「12」、「ロ」、「口」、「72」、「に」、「R」等の文字が表示される。 The character display unit 14 displays the input characters in accordance with instructions from the control unit 13 (step S25). Thereafter, the control unit 13 waits until a candidate display operation is performed by the user via the user operation unit 15 or the like (step S26). In this candidate display operation, the focus position a (see FIG. 7) is moved by pressing the left key 15d or the right key 15e, and the candidate character group is displayed at the position of the handwriting input unit 11 by pressing the conversion key 15b. This is the operation to focus on. FIG. 8 is a diagram illustrating an example of a candidate character group displayed at the position of the handwriting input unit 11. Here, characters such as “12”, “B”, “mouth”, “72”, “ni”, and “R” are displayed as candidate characters for the character “12”.
 続いて、制御部13は、図7(B)に示すように、フォーカス位置aにある文字の認識候補(ここでは、「12」)が選択されたか否かを判別する(ステップS27)。選択されていない場合、文字入力装置1は、ステップS25の処理に戻る。 Subsequently, as shown in FIG. 7B, the control unit 13 determines whether or not a character recognition candidate (here, “12”) at the focus position a has been selected (step S27). If not selected, the character input device 1 returns to the process of step S25.
 一方、認識候補が選択された場合、制御部13は、訂正キー15cが押下され、入力文字を書き直すか否かを判別する(ステップS28)。書き直す場合、制御部13は、フォーカス位置aにある文字の修正に移行し(ステップS29)、ステップS21の処理に戻る。図7(C)では、フォーカス位置aにある文字「12」が「14」に書き直された場合が示されている。 On the other hand, when the recognition candidate is selected, the control unit 13 determines whether or not to rewrite the input character by pressing the correction key 15c (step S28). When rewriting, the control unit 13 shifts to correction of the character at the focus position a (step S29) and returns to the process of step S21. FIG. 7C shows a case where the character “12” at the focus position a is rewritten to “14”.
 一方、ステップS28でユーザが書き直さない場合、制御部13は、確定キー15fが押下されたか否かを判別する(ステップS30)。文字入力装置1は、確定キー15fが押下されない場合、ステップS25の処理に戻る。一方、確定キー15fが押下された場合、ステップS21の処理に戻る。 On the other hand, when the user does not rewrite in step S28, the control unit 13 determines whether or not the confirmation key 15f is pressed (step S30). If the enter key 15f is not pressed, the character input device 1 returns to the process of step S25. On the other hand, if the enter key 15f is pressed, the process returns to step S21.
 このように、記憶部としてのメモリ13aは、文字認識部12により認識された複数の文字で構成された文字列の各文字に対応させて同一の配列番号の情報を記憶してもよい。制御部13は、メモリ13aに記憶された同一の配列番号に対応する文字を1つの文字として、文字列の表示時又は編集時の制御を行うようにしてもよい。これにより、認識候補の表示(文字列の候補の表示の制御)や書き直し(書き直し処理)を行う場合も、ユーザが文字記入領域11aに記入した複数桁の数字と同じように扱うことができ、ユーザは違和感を生じない。 As described above, the memory 13a as the storage unit may store the information of the same array number corresponding to each character of the character string composed of a plurality of characters recognized by the character recognition unit 12. The control unit 13 may perform control at the time of displaying or editing a character string, with a character corresponding to the same array number stored in the memory 13a as one character. As a result, even when displaying recognition candidates (controlling the display of character string candidates) and rewriting (rewriting processing), it can be handled in the same way as a multi-digit number entered by the user in the character entry area 11a. The user does not feel uncomfortable.
 第1の実施形態の文字入力装置によれば、複数の文字で構成された文字列が入力された場合も、入力時と表示時及び編集時とで文字数が一致し、違和感が生じることなく、操作することができる。 According to the character input device of the first embodiment, even when a character string composed of a plurality of characters is input, the number of characters matches at the time of input, at the time of display, and at the time of editing, without causing a sense of incongruity. Can be operated.
(第2の実施形態)
 第1の実施形態では、文字記入領域に複数桁の数字が入力された場合、複数桁分のカーソルおよびフォーカス移動が行われ、かつ、複数桁の候補文字が表示された。第2の実施形態では、第1の実施形態の動作の他、複数桁の候補文字を表示する一方、カーソル/フォーカス移動においては1文字ずつ行う動作も可能である。
(Second Embodiment)
In the first embodiment, when a plurality of digits are entered in the character entry area, a plurality of digits of the cursor and focus are moved, and a plurality of digits of candidate characters are displayed. In the second embodiment, in addition to the operation of the first embodiment, a plurality of digits of candidate characters can be displayed, while the cursor / focus movement can be performed one character at a time.
 図9は本発明の第2の実施形態における文字入力装置1Aの構成例を示すブロック図である。文字入力装置1Aは第1の実施形態における文字入力装置1とほぼ同一の構成を有するので、第1の実施形態と同一の構成要素については同一の符号を用いることで、その説明を省略し、ここでは異なる構成要素について説明する。 FIG. 9 is a block diagram showing a configuration example of the character input device 1A according to the second embodiment of the present invention. Since the character input device 1A has substantially the same configuration as the character input device 1 in the first embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Here, different components will be described.
 文字入力装置1Aには、選択制御部23が設けられている。選択制御部23は、第1の実施形態と同様の制御(第1の制御)を行う制御部13と、後述する制御(第2の制御)を行う制御部13Aと、を有し、これらの制御を切り替える。この切り替え動作は、例えばユーザ操作部15のキー操作によりユーザが行なえる。また、選択制御部23は、例えば、ソフトウェアスイッチで構成されてもよいし、ハードウェアスイッチで構成されてもよい。 The character input device 1A is provided with a selection control unit 23. The selection control unit 23 includes a control unit 13 that performs the same control (first control) as in the first embodiment, and a control unit 13A that performs control (second control) described later. Switch control. This switching operation can be performed by the user by a key operation of the user operation unit 15, for example. Further, the selection control unit 23 may be configured with, for example, a software switch or a hardware switch.
 制御部13Aには、制御部13と同様、メモリ13Aa、フォーカス/カーソル位置制御部13Ab、および文字認識制御部13Acが設けられている。 As with the control unit 13, the control unit 13A is provided with a memory 13Aa, a focus / cursor position control unit 13Ab, and a character recognition control unit 13Ac.
 制御部13Aは、複数桁の候補文字が確定した後、文字認識部12のメモリ12aに記憶されている複数桁の筆跡および候補文字を削除し、メモリ13Aaに記憶されている1文字ずつの筆跡をメモリ12aに再入力して文字を認識させる。 The control unit 13A deletes the multi-digit handwriting and the candidate character stored in the memory 12a of the character recognition unit 12 after the multi-digit candidate character is confirmed, and the handwritten character by character stored in the memory 13Aa. Is re-input to the memory 12a to recognize the character.
 図10は認識候補の表示とカーソルおよびフォーカスの移動手順の一例を示すフローチャートである。この動作を行う文字入力プログラムは、文字入力装置1A内のROMに格納され、文字入力装置1A内のCPUによって実行される。図10では、選択制御部23によって第2の制御を行うよう選択されている場合を想定する。 FIG. 10 is a flowchart showing an example of recognition candidate display and cursor and focus movement procedures. A character input program for performing this operation is stored in the ROM in the character input device 1A, and is executed by the CPU in the character input device 1A. In FIG. 10, it is assumed that the selection control unit 23 is selected to perform the second control.
 まず、制御部13Aは、筆跡入力部11により筆跡が入力されたか否かを判別する(ステップS31)。筆跡が入力されない場合、文字入力装置1AはステップS35の処理に進む。 First, the control unit 13A determines whether or not a handwriting is input by the handwriting input unit 11 (step S31). If the handwriting is not input, the character input device 1A proceeds to the process of step S35.
 一方、筆跡入力部11による筆跡の入力があると、文字認識部12は、入力された筆跡に対応する文字を認識する(ステップS32)。このとき、入力文字が複数桁の数字である場合には、複数桁の筆跡および候補文字がメモリ12aに記憶される。 On the other hand, when a handwriting is input by the handwriting input unit 11, the character recognition unit 12 recognizes a character corresponding to the input handwriting (step S32). At this time, if the input character is a multi-digit number, the multi-digit handwriting and the candidate character are stored in the memory 12a.
 制御部13Aは、文字認識部12から認識された文字コードを受け取り、制御部13A内のメモリ13Aaに記憶する(ステップS33)。このとき、認識された文字が複数桁の数字である場合、文字認識部12から受け取る文字コードは、第1の実施形態と同様に、複数桁の数字に対応する個々の文字コードである。制御部13Aは、この文字コードをメモリ13Aaに記憶する。 The control unit 13A receives the character code recognized from the character recognition unit 12, and stores it in the memory 13Aa in the control unit 13A (step S33). At this time, if the recognized character is a multi-digit number, the character code received from the character recognition unit 12 is an individual character code corresponding to the multi-digit number, as in the first embodiment. The control unit 13A stores this character code in the memory 13Aa.
 制御部13Aは、複数桁の数字などの文字列の場合、認識された文字を修正する動作を行う(ステップS34)。ここでは、制御部13Aは、文字認識部12のメモリ12aに記憶されている複数桁の筆跡および候補文字を削除し、メモリ13Aaに記憶されている1文字ずつの筆跡をメモリ12aに再入力し、文字を認識させる。これにより、複数桁の筆跡に対応する候補文字に基づき、メモリ12aには、1文字ずつの筆跡および候補文字が記憶される。 The control unit 13A performs an operation of correcting the recognized character in the case of a character string such as a multi-digit number (step S34). Here, the control unit 13A deletes the multi-digit handwriting and the candidate character stored in the memory 12a of the character recognition unit 12, and re-inputs the handwritten character by character stored in the memory 13Aa to the memory 12a. , Make characters recognized. Thereby, based on the candidate character corresponding to the handwriting of multiple digits, the handwriting and the candidate character for each character are stored in the memory 12a.
 図11は文字認識後、認識された文字の筆跡を文字認識部12に再入力して修正される認識文字の一例を示す図である。複数桁の候補文字として「12」が認識され、「12」その他の候補文字として「72」が認識され、これらがメモリ12aに記憶された後、制御部13Aは、以下のような動作を行う。すなわち、制御部13Aは、文字認識部12のメモリ12aに記憶されている複数桁の文字の筆跡を削除し、代わりに、メモリ13Aaに記憶されている候補文字「1」、「2」、および、文字「7」、「2」の筆跡を文字認識部12に再入力する。これにより、複数桁の候補文字が表示された後、文字認識部12のメモリ12aには、候補文字「1」、「2」、その他の候補文字「7」、「2」が記憶される。 FIG. 11 is a diagram illustrating an example of a recognized character that is corrected by re-inputting the handwriting of the recognized character into the character recognition unit 12 after character recognition. After “12” is recognized as a multi-digit candidate character and “72” is recognized as “12” and other candidate characters, and these are stored in the memory 12a, the control unit 13A performs the following operation. . That is, the control unit 13A deletes the handwriting of the multi-digit characters stored in the memory 12a of the character recognition unit 12, and instead of the candidate characters “1”, “2”, and The handwriting of the characters “7” and “2” is re-input to the character recognition unit 12. Thus, after the multi-digit candidate characters are displayed, the candidate characters “1” and “2” and the other candidate characters “7” and “2” are stored in the memory 12a of the character recognition unit 12.
 文字表示部14は、制御部13Aの指示に従って、入力文字を表示する(ステップS35)。 The character display unit 14 displays the input characters in accordance with the instruction from the control unit 13A (step S35).
 この後、制御部13Aは、ユーザ操作部15のうち、左キー15dが押下されたか否かを判別する(ステップS36)。左キー15dが押下されない場合、文字入力装置1Aは、ステップS31の処理に戻る。 Thereafter, the control unit 13A determines whether or not the left key 15d of the user operation unit 15 is pressed (step S36). If the left key 15d is not pressed, the character input device 1A returns to the process of step S31.
 一方、左キー15dが押下された場合、制御部13Aは、文字表示部14に表示された文字列に対し、カーソルを1つ移動させ(ステップS37)、1文字分のフォーカスを当てる(ステップS38)。この後、文字入力装置1Aは、ステップS35の処理に戻る。 On the other hand, when the left key 15d is pressed, the control unit 13A moves the cursor by one to the character string displayed on the character display unit 14 (step S37), and focuses one character (step S38). ). Thereafter, the character input device 1A returns to the process of step S35.
 図12はカーソルおよびフォーカスの移動の一例を示す図である。左キー15dを押下する前、カーソルおよびフォーカスは、文字列「明日の12時に、」のうち、文字「時」の位置にあったが、左キー15dを押下すると、カーソルおよびフォーカスは、複数桁の数字からなる文字列「2」の位置に移動する。さらに、左キー15dを押下すると、カーソルおよびフォーカスは、文字「1」の位置に移動する。 FIG. 12 is a diagram showing an example of cursor and focus movement. Before the left key 15d was pressed, the cursor and focus were at the position of the character “hour” in the character string “12 o'clock tomorrow”. Move to the position of the character string “2” consisting of the numbers. Furthermore, when the left key 15d is pressed, the cursor and focus move to the position of the character “1”.
 このように、第2の実施形態では、文字入力装置1Aが、第1の制御と第2の制御とを切り替える制御部としての選択制御部23を備えている。第1の制御では、文字認識部12によって認識された複数の文字で構成された文字列の文字数に応じてこの文字列の表示時および編集時の制御を行う。第2の制御では、この文字列の表示時又は編集時に前記文字数に応じた制御を行わない。このような文字入力装置1Aによれば、複数桁の数字等の文字列を入力する場合、第1の実施形態と同様の動作を行わせることができる他、制御を切り替えることにより、候補文字の変換だけを複数桁の数字で行わせ、カーソルやフォーカス、削除等の制御を1文字ずつ行わせることも可能である。これにより、ユーザの嗜好に合わせた入力操作が可能となる。 As described above, in the second embodiment, the character input device 1A includes the selection control unit 23 as a control unit that switches between the first control and the second control. In the first control, control at the time of display and editing of the character string is performed according to the number of characters of the character string composed of a plurality of characters recognized by the character recognition unit 12. In the second control, control according to the number of characters is not performed when the character string is displayed or edited. According to such a character input device 1A, when inputting a character string such as a multi-digit number, it is possible to perform the same operation as in the first embodiment, and by switching the control, It is also possible to perform only conversion with a plurality of digits, and to perform control such as cursor, focus, and deletion one character at a time. Thereby, the input operation according to the user's preference is possible.
 なお、本発明は、上記実施形態の構成に限られるものではなく、特許請求の範囲で示した機能、または本実施形態の構成が持つ機能が達成できる構成であればどのようなものであっても適用可能である。 The present invention is not limited to the configuration of the above-described embodiment, and any configuration can be used as long as the functions shown in the claims or the functions of the configuration of the present embodiment can be achieved. Is also applicable.
 例えば、上記実施形態では、複数桁の文字を入力する例として、2桁の数字を挙げたが、これに限られるものではない。複数桁の文字からなる文字列として、アルファベットでは血液型の「AB」、ひらがなでは「あした」、記号では「+-」、記号と数字の組み合わせでは「30℃」など、種々挙げることができる。 For example, in the above embodiment, a two-digit number is given as an example of inputting a multi-digit character. However, the present invention is not limited to this. As a character string composed of a plurality of digits, various characters such as “AB” of blood type in alphabet, “Ashita” in hiragana, “+ −” in symbol, “30 ° C.” in combination of symbol and number can be cited.
 また、上記実施形態は、定型文を表示、編集する場合にも有効である。例えば、文字入力装置は、入力された筆跡から1つの文字「あ」を認識し、この文字に対応する、複数の文字で構成された文字列の候補「あした」を表示する。そして、文字入力装置は、この文字列の候補の文字数に応じて、カーソルやフォーカスの移動、削除などを行うようにしてもよい。 Also, the above embodiment is effective when displaying and editing a fixed phrase. For example, the character input device recognizes one character “A” from the input handwriting and displays a character string candidate “Ashita” composed of a plurality of characters corresponding to this character. The character input device may move or delete the cursor or focus according to the number of characters as candidates for the character string.
 このように、文字認識部12は、所定の領域としての文字記入領域11aに入力された筆跡から1つの文字(例えば「あ」)を認識してもよい。表示部としての文字表示部14は、文字認識部12により認識された1つの文字から複数の文字列で構成された文字列の候補(例えば「あした」)を表示してもよい。制御部13は、文字列の候補の文字数に応じて、文字列の候補の文字表示部14による表示時又は編集時の制御を行うようにしてもよい。これにより、定型文の表示や編集が簡単になる。 As described above, the character recognition unit 12 may recognize one character (for example, “A”) from the handwriting input in the character entry area 11a as a predetermined area. The character display unit 14 as a display unit may display a character string candidate (for example, “Tomorrow”) composed of a plurality of character strings from one character recognized by the character recognition unit 12. The control unit 13 may perform control at the time of display or editing by the character display unit 14 of the character string candidates according to the number of characters of the character string candidates. This makes it easy to display and edit fixed phrases.
 また、本発明は、上記実施形態の機能を実現する文字入力プログラムを、ネットワークあるいは各種記憶媒体を介して文字入力装置に供給し、この文字入力装置内のコンピュータが読み出して実行するプログラムも適用範囲である。 The present invention also includes a program that supplies a character input program that realizes the functions of the above-described embodiments to a character input device via a network or various storage media, and that is read and executed by a computer in the character input device. It is.
 また、上記実施形態の文字入力装置は、手書き入力機能を有する電子機器として、単体の装置であってもよく、スマートフォンやタブレット端末など各種の電子機器に搭載されてもよい。 In addition, the character input device of the above embodiment may be a single device as an electronic device having a handwriting input function, and may be mounted on various electronic devices such as a smartphone and a tablet terminal.
 本発明を詳細にまた特定の実施態様を参照して説明したが、本発明の精神と範囲を逸脱することなく様々な変更や修正を加えることができることは当業者にとって明らかである。
