　以下、本実施の形態を図面を参照して説明する。
　［第１の実施の形態］
　図１は、第１の実施の形態の情報処理装置を示す図である。情報処理装置１０は、入力デバイス２および表示装置３に接続されている。入力デバイス２は、入力キー＃１，＃２，＃３，＃４，＃５，＃６を有する。入力デバイス２は、各入力キーが押下されるか否かを示す信号を情報処理装置１０に出力する。表示装置３は、表示画面３ａを備える。表示装置３は、情報処理装置１０の命令に従い、表示画面３ａに画像を表示する。画像には、情報処理装置１０による指示、操作の対象を特定するための指示画像３ｂが含まれる。指示画像３ｂは、例えば、マウスカーソル、あるいは、文字の入力位置を示すポインタである。なお、入力デバイス２および表示装置３は、情報処理装置１０と一体化されていてもよい。 Hereinafter, the present embodiment will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a diagram illustrating the information processing apparatus according to the first embodiment. The information processing apparatus 10 is connected to the input device 2 and the display apparatus 3. The input device 2 has input keys # 1, # 2, # 3, # 4, # 5, and # 6. The input device 2 outputs a signal indicating whether or not each input key is pressed to the information processing apparatus 10. The display device 3 includes a display screen 3a. The display device 3 displays an image on the display screen 3a according to the instruction of the information processing device 10. The image includes an instruction image 3b for specifying an instruction and an operation target by the information processing apparatus 10. The instruction image 3b is, for example, a mouse cursor or a pointer indicating a character input position. Note that the input device 2 and the display device 3 may be integrated with the information processing apparatus 10.
　情報処理装置１０は、入力デバイス２から取得した入力信号に応じて、表示画面３ａに表示させる画像を制御するノート型コンピュータや携帯端末などの情報処理装置である。情報処理装置１０は、デバイスドライバやＯＳ（Operating System）など、入力デバイス２への入力操作に応じて表示装置３における表示画面３ａの画像表示を制御するソフトウェアを有する。 The information processing apparatus 10 is an information processing apparatus such as a notebook computer or a portable terminal that controls an image to be displayed on the display screen 3a in accordance with an input signal acquired from the input device 2. The information processing apparatus 10 includes software that controls image display on the display screen 3a in the display device 3 in accordance with an input operation to the input device 2, such as a device driver or an OS (Operating System).
　情報処理装置１０は、記憶部１１、判定部１２および表示制御部１３を有する。記憶部１１は、例えば、ＲＡＭ（Random Access Memory）などの揮発性メモリ、あるいは、ＨＤＤ（Hard Disk Drive）やフラッシュメモリなどの不揮発性記憶装置によって実現される。判定部１２および表示制御部１３は、例えば、ＣＰＵ（Central Processing Unit）やＤＳＰ（Digital Signal Processor）などのプロセッサや、ＡＳＩＣ（Application Specific Integrated Circuit）やＦＰＧＡ（Field Programmable Gate Array）などのその他の電子回路を用いて実現される。プロセッサは、例えば、メモリに記憶されたプログラムを実行する。プロセッサは、プログラムの命令を実行するための演算器やレジスタの他に、データ処理のための専用の回路を含んでいてもよい。 The information processing apparatus 10 includes a storage unit 11, a determination unit 12, and a display control unit 13. The storage unit 11 is realized by, for example, a volatile memory such as a RAM (Random Access Memory) or a nonvolatile storage device such as an HDD (Hard Disk Drive) or a flash memory. The determination unit 12 and the display control unit 13 are, for example, a processor such as a CPU (Central Processing Unit) and a DSP (Digital Signal Processor), and other electronic devices such as an ASIC (Application Specific Integrated Circuit) and an FPGA (Field Programmable Gate Array). This is realized using a circuit. The processor executes, for example, a program stored in the memory. The processor may include a dedicated circuit for data processing in addition to an arithmetic unit and a register for executing program instructions.
　記憶部１１は、入力デバイス２が有する各入力キーの位置関係を示す情報を記憶する。判定部１２は、入力デバイス２から各入力キーにおける押下される状態を示す入力信号を取得する。判定部１２は、取得した入力信号を基に押下される入力キーを識別する。判定部１２は、押下される入力キーが変更される毎に、変更前の入力キーと変更後の入力キーの各位置に基づいて、指示画像３ｂの移動方向を判定する。例えば、判定部１２は、押下される入力キーが変更される毎に、記憶部１１に記憶された位置関係を示す情報に基づいて変更前の入力キーと変更後の入力キーの位置関係を判別し、判別した位置関係に基づいて指示画像３ｂの移動方向を判定する。表示制御部１３は、判定部１２により判定された指示画像３ｂの移動方向に指示画像３ｂの表示位置を移動させる。 The storage unit 11 stores information indicating the positional relationship between the input keys of the input device 2. The determination unit 12 acquires an input signal indicating a pressed state of each input key from the input device 2. The determination unit 12 identifies an input key that is pressed based on the acquired input signal. Each time the input key to be pressed is changed, the determination unit 12 determines the moving direction of the instruction image 3b based on the positions of the input key before the change and the input key after the change. For example, each time the input key to be pressed is changed, the determination unit 12 determines the positional relationship between the input key before the change and the input key after the change based on the information indicating the positional relationship stored in the storage unit 11. Then, based on the determined positional relationship, the moving direction of the instruction image 3b is determined. The display control unit 13 moves the display position of the instruction image 3b in the moving direction of the instruction image 3b determined by the determination unit 12.
　例えば、指示画像３ｂが表示画面３ａの（Ｐ１）の位置に存在する場合において、入力キー＃４→入力キー＃５→入力キー＃２の順に押下されたときの指示画像３ｂの表示位置について説明する。まず、入力キー＃４が押下されたとき、判定部１２は、例えば、入力キー＃４の入力操作の前に押下される入力キーが存在しないため、指示画像３ｂの移動方向を判定しないものとする。この場合、指示画像３ｂの表示位置は表示画面３ａの（Ｐ１）のままである。 For example, when the instruction image 3b is present at the position (P1) on the display screen 3a, the display position of the instruction image 3b when the input key # 4 → the input key # 5 → the input key # 2 is pressed in this order will be described. To do. First, when the input key # 4 is pressed, the determination unit 12 does not determine the moving direction of the instruction image 3b, for example, because there is no input key pressed before the input operation of the input key # 4. To do. In this case, the display position of the instruction image 3b remains (P1) on the display screen 3a.
　次に、押下される入力キーが入力キー＃５に変更されたとき、判定部１２は、例えば、変更前の入力キー＃４の右方向に変更後の入力キー＃５があるため、指示画像３ｂの移動方向を「右」と判定する。表示制御部１３は、判定部１２に判定された右方向に、指示画像３ｂの表示位置を移動させる。 Next, when the input key to be pressed is changed to the input key # 5, the determination unit 12 has, for example, the input key # 5 after the change in the right direction of the input key # 4 before the change. The moving direction of 3b is determined as “right”. The display control unit 13 moves the display position of the instruction image 3b in the right direction determined by the determination unit 12.
　次に、表示画面３ａの（Ｐ２）の位置に指示画像３ｂが移動中、押下される入力キーが入力キー＃２に変更される。このとき、判定部１２は、例えば、変更前の入力キー＃５の上方向に変更後の入力キー＃２があるため、指示画像３ｂの移動方向を「上」と判定する。表示制御部１３は、判定部１２に判定された上方向に、指示画像３ｂの表示位置を移動させる。そして、例えば、指示画像３ｂが表示画面３ａの（Ｐ３）の位置に達したとき、入力キー＃２の押下が終了すると、表示制御部１３は、例えば、指示画像３ｂの表示位置を表示画面３ａの（Ｐ３）の位置で停止させる。 Next, while the instruction image 3b is moving to the position (P2) on the display screen 3a, the input key to be pressed is changed to the input key # 2. At this time, for example, the determination unit 12 determines that the moving direction of the instruction image 3b is “up” because there is the input key # 2 after the change in the upward direction of the input key # 5 before the change. The display control unit 13 moves the display position of the instruction image 3b in the upward direction determined by the determination unit 12. For example, when the instruction image 3b reaches the position (P3) of the display screen 3a, when the pressing of the input key # 2 is finished, the display control unit 13 displays the display position of the instruction image 3b, for example, on the display screen 3a. (P3) is stopped.
　第１の実施の形態によれば、押下される入力キーが変更される毎に、変更前後の入力キーの位置関係から、指示画像３ｂの表示位置の移動方向を判定し、判定した移動方向へ指示画像３ｂの表示位置を移動させる。 According to the first embodiment, each time the input key to be pressed is changed, the moving direction of the display position of the instruction image 3b is determined from the positional relationship between the input keys before and after the change, and the determined moving direction is reached. The display position of the instruction image 3b is moved.
　これにより、ユーザは、入力キー＃１，＃２，＃３，＃４，＃５，＃６の入力操作により指示画像３ｂの表示位置を移動させることができる。例えば、ユーザは、ノート型コンピュータにおいて、配置スペースが広いタッチパッドや厚みのあるポインティングスティックを用いずに指示画像の表示位置を移動させることができる。その結果、ノート型コンピュータなどの情報処理装置１０において、小型化、薄型化が可能となり、タッチパッドやポインティングスティックなどのコストを節約できる。 Thereby, the user can move the display position of the instruction image 3b by the input operation of the input keys # 1, # 2, # 3, # 4, # 5, and # 6. For example, in a notebook computer, the user can move the display position of the instruction image without using a touch pad having a large arrangement space or a thick pointing stick. As a result, the information processing apparatus 10 such as a notebook computer can be reduced in size and thickness, and the cost of a touch pad or a pointing stick can be saved.
　また、ユーザは、押下する入力キーを変更することで、連続的に指示画像３ｂの表示位置の移動方向を変更することができる。よって、指示画像の表示位置の移動方向を変更するために、入力キーへの入力操作を２回行う特許文献１に記載の方法などと比べ、操作性が向上する。 Further, the user can continuously change the moving direction of the display position of the instruction image 3b by changing the input key to be pressed. Therefore, the operability is improved as compared with the method described in Patent Document 1 in which the input operation to the input key is performed twice in order to change the moving direction of the display position of the instruction image.
　なお、表示制御部１３は、判定部１２により判定された移動方向が移動中である指示画像３ｂの移動方向と同じ場合、指示画像３ｂの表示位置の移動速度を変更させてもよい。また、判定部１２は、入力キーの押下された時間が閾値未満の場合、入力キーが押下されていないとみなしてもよい。また、情報処理装置１０における入力キーによる指示画像３ｂの表示位置を移動させる機能の有効・無効は、例えば、「ｆ」キーおよび「ｊ」キーを同時に押下するなどの所定の操作により切替えることができる。 The display control unit 13 may change the moving speed of the display position of the instruction image 3b when the movement direction determined by the determination unit 12 is the same as the movement direction of the instruction image 3b that is moving. Moreover, the determination part 12 may consider that the input key is not pressed, when the time when the input key was pressed is less than a threshold value. Further, the validity / invalidity of the function of moving the display position of the instruction image 3b by the input key in the information processing apparatus 10 can be switched by a predetermined operation such as pressing the “f” key and the “j” key at the same time. it can.
　［第２の実施の形態］
　第２の実施の形態では、ノート型コンピュータなどのディスプレイやキーボードが一体化されたコンピュータにおいて、ディスプレイに表示されるマウスカーソルの表示位置をキーボードの入力キーで制御する方法について説明する。まず、第２の実施の形態のコンピュータにおけるハードウェアや機能の構成について説明する。 [Second Embodiment]
In the second embodiment, a method of controlling a display position of a mouse cursor displayed on a display with an input key of a keyboard in a computer such as a notebook computer in which a display and a keyboard are integrated will be described. First, the hardware and functional configurations of the computer according to the second embodiment will be described.

The image displayed on the display 101 includes a mouse cursor. As the display 101, a liquid crystal display or the like can be used. The keyboard 102 is an input device having a plurality of input keys. The keyboard 102 outputs a signal indicating whether or not each input key is pressed to the input signal processing unit 107.
　コンピュータ１００は、キーボード１０２が有する入力キーの操作により、ディスプレイ１０１に表示されるマウスカーソルの表示位置を移動する機能を有する。コンピュータ１００は、キーボード１０２の入力キーの操作によってマウスカーソルの表示位置を移動する機能の有効・無効を、例えば、キーボード１０２上の所定の入力キーを閾値以上の時間押下し続けるなどの特定の操作により切替えることができる。なお、上記機能が無効の状態では、キーボード１０２の各入力キーは、それぞれに対応付けられた文字の入力のために使用される。 The computer 100 has a function of moving the display position of the mouse cursor displayed on the display 101 by operating the input keys of the keyboard 102. The computer 100 determines whether the function of moving the display position of the mouse cursor by operating the input key of the keyboard 102 is valid / invalid, for example, a specific operation such as continuously pressing a predetermined input key on the keyboard 102 for a time longer than a threshold value. Can be switched. When the above function is disabled, each input key of the keyboard 102 is used for inputting a character associated with the input key.

The CPU 103, RAM 104, HDD 105, image signal processing unit 106, input signal processing unit 107, disk drive 108, and communication interface 109 are connected to a bus 110 provided in the computer 100. The display 101 is connected to the image signal processing unit 106, and the keyboard 102 is connected to the input signal processing unit 107.
　ＣＰＵ１０３は、プログラムの命令を実行する演算器を含むプロセッサである。ＣＰＵ１０３は、ＨＤＤ１０５に記憶されているプログラムやデータの少なくとも一部をＲＡＭ１０４にロードし、プログラムを実行する。なお、ＣＰＵ１０３は複数のプロセッサコアを備えてもよく、コンピュータ１００は複数のプロセッサを備えてもよい。また、コンピュータ１００は、以下で説明する処理を複数のプロセッサまたはプロセッサコアを用いて並列実行してもよい。 The CPU 103 is a processor including an arithmetic unit that executes program instructions.

　上記のように、コンピュータ１００は、キーボード１０２が有する入力キーの操作により、ディスプレイ１０１に表示されるマウスカーソルの表示位置を移動させることができる。これにより、マウスカーソルの表示位置を移動させるために、配置スペースが広いタッチパッドや厚みのあるポインティングスティックを用いる場合に比べ、コンピュータ１００をより小型化、薄型化することができる。また、タッチパッドやポインティングスティックを搭載しない分、コンピュータ１００を製造するコストを抑えることができる。 However, the computer 100 may not include the disk drive 108 and the communication interface 109.

In addition, the cost of manufacturing the computer 100 can be reduced by the amount that the touch pad and the pointing stick are not installed.
　図３は、コンピュータの機能例を示すブロック図である。コンピュータ１００は、キー配列情報記憶部１２０、移動方向判定部１３０およびマウスカーソル制御部１４０を有する。キー配列情報記憶部１２０は、例えば、ＲＡＭ１０４やＨＤＤ１０５などの記憶装置によって実現される。移動方向判定部１３０およびマウスカーソル制御部１４０の処理は、例えば、デバイスドライバまたはＯＳなどのソフトウェアをＣＰＵ１０３が実行することにより実現される。 FIG. 3 is a block diagram illustrating an example of functions of a computer. The computer 100 includes a key arrangement information storage unit 120, a movement direction determination unit 130, and a mouse cursor control unit 140. The key arrangement information storage unit 120 is realized by a storage device such as the RAM 104 or the HDD 105, for example. The processing of the movement direction determination unit 130 and the mouse cursor control unit 140 is realized by the CPU 103 executing software such as a device driver or OS, for example.
　キー配列情報記憶部１２０は、キーボード１０２に配列された入力キーの位置関係を示すキー配列情報を記憶する。
　移動方向判定部１３０は、キーボード１０２から押下される入力キーの状態を示す入力信号を取得する。移動方向判定部１３０は、取得した入力信号により、押下される入力キーの状態を検知する。入力キーが押下された時間が閾値未満の場合、移動方向判定部１３０は、入力キーが押下されていないとみなす。移動方向判定部１３０は、押下される入力キーが変更されたときに、キー配列情報に基づき、変更前後の入力キーの位置関係を算出する。移動方向判定部１３０は、算出した位置関係からディスプレイ１０１上のマウスカーソルの表示位置の移動方向を判定する。 The key arrangement information storage unit 120 stores key arrangement information indicating the positional relationship of the input keys arranged on the keyboard 102.
The movement direction determination unit 130 acquires an input signal indicating the state of the input key pressed from the keyboard 102. The movement direction determination unit 130 detects the state of the input key that is pressed based on the acquired input signal. When the time when the input key is pressed is less than the threshold, the movement direction determination unit 130 considers that the input key is not pressed. When the input key to be pressed is changed, the movement direction determination unit 130 calculates the positional relationship of the input key before and after the change based on the key arrangement information. The movement direction determination unit 130 determines the movement direction of the display position of the mouse cursor on the display 101 from the calculated positional relationship.
　マウスカーソル制御部１４０は、マウスカーソルの表示位置を制御する。マウスカーソル制御部１４０は、マウスカーソルが移動中でない場合、移動方向判定部１３０が判定した移動方向に対して、マウスカーソルの表示位置を移動させる。マウスカーソル制御部１４０は、マウスカーソルが移動中の場合、移動方向判定部１３０が判定した移動方向と、移動中であるマウスカーソルの移動方向とを比較する。各移動方向が同じ場合、マウスカーソル制御部１４０は、マウスカーソルの表示位置の移動速度を上げる。各移動方向が異なる場合、マウスカーソル制御部１４０は、マウスカーソルの表示位置の移動方向を変更する。なお、マウスカーソルの移動方向や移動速度に関する情報は、コンピュータ１００が有するＣＰＵ１０３が有するレジスタなどの記憶領域に記憶される。 The mouse cursor control unit 140 controls the display position of the mouse cursor. When the mouse cursor is not moving, the mouse cursor control unit 140 moves the display position of the mouse cursor with respect to the movement direction determined by the movement direction determination unit 130. When the mouse cursor is moving, the mouse cursor control unit 140 compares the movement direction determined by the movement direction determination unit 130 with the movement direction of the moving mouse cursor. When the moving directions are the same, the mouse cursor control unit 140 increases the moving speed of the display position of the mouse cursor. When the movement directions are different, the mouse cursor control unit 140 changes the movement direction of the display position of the mouse cursor. Information about the moving direction and moving speed of the mouse cursor is stored in a storage area such as a register of the CPU 103 of the computer 100.
　図４は、キーボードにおけるキーの配置例およびキー配列情報の例を示す図である。キーボード１０２は複数の入力キーを有しており、図４ではそれらの入力キーのうち、例として入力キー＃１１，＃１２，＃１３，＃２１，＃２２，＃２３，＃３１，＃３２，＃３３を示す。 FIG. 4 is a diagram showing an example of key arrangement and key arrangement information on the keyboard. The keyboard 102 has a plurality of input keys. In FIG. 4, among these input keys, as an example, the input keys # 11, # 12, # 13, # 21, # 22, # 23, # 31, # 32 , # 33.
　入力キー＃１１，＃１２，＃１３は上段に、入力キー＃２１，＃２２，＃２３は中段に、入力キー＃３１，＃３２，＃３３は下段に配列されている。また、入力キー＃１１の左斜め下に入力キー＃２１が配置され、入力キー＃２１の左斜め下に入力キー＃３１が配置されている。また、入力キー＃１２の左斜め下に入力キー＃２２が配置され、入力キー＃２２の左斜め下に入力キー＃３２が配置されている。また、入力キー＃１３の左斜め下に入力キー＃２３が配置され、入力キー＃２３の左斜め下に入力キー＃３３が配置されている。 The input keys # 11, # 12 and # 13 are arranged in the upper stage, the input keys # 21, # 22 and # 23 are arranged in the middle stage, and the input keys # 31, # 32 and # 33 are arranged in the lower stage. Further, the input key # 21 is arranged diagonally to the left of the input key # 11, and the input key # 31 is arranged diagonally to the left of the input key # 21. Further, the input key # 22 is arranged diagonally to the left of the input key # 12, and the input key # 32 is arranged diagonally to the left of the input key # 22. Further, the input key # 23 is arranged diagonally to the left of the input key # 13, and the input key # 33 is arranged diagonally to the left of the input key # 23.
　キー配列情報１２１は、キーボード１０２に配列された各入力キーの位置関係を定義した情報である。キー配列情報１２１は、キー配列情報記憶部１２０に記憶されている。キー配列情報１２１は、押下される入力キーが変更されたときに変更前後における入力キーの位置関係を算出するために移動方向判定部１３０により参照される。キー配列情報１２１には、キーボード１０２において、右上から左下方向に並ぶ入力キー（例えば、入力キー＃１１，＃２１，＃３１）が縦方向に設定され、左から右方向に並ぶ入力キー（例えば、入力キー＃１１，＃１２，＃１３）が横方向に設定される。 The key arrangement information 121 is information that defines the positional relationship of the input keys arranged on the keyboard 102. The key arrangement information 121 is stored in the key arrangement information storage unit 120. The key arrangement information 121 is referred to by the movement direction determination unit 130 in order to calculate the positional relationship of the input keys before and after the change when the input key to be pressed is changed. In the keyboard layout information 121, input keys (for example, input keys # 11, # 21, and # 31) arranged in the vertical direction from the upper right on the keyboard 102 are set in the vertical direction, and input keys (for example, input from the left to the right) (for example, , Input keys # 11, # 12, # 13) are set in the horizontal direction.
　なお、キー配列情報１２１には、キーボード１０２において、左上から右下方向に並ぶ入力キー（例えば、入力キー＃１１，＃２２，＃３３）が縦方向に設定されてもよい。
　上記のキー配列情報１２１は、キーボード１０２が有する各入力キーを基準キーとしたとき、各基準キーの周囲の入力キーが基準キーからどの方向にあるのかを定義したものである。例えば図４において、入力キー＃２２を基準キーとしたとき、入力キー＃１２は上方向の入力キーであり、入力キー＃３２は下方向の入力キーであり、入力キー＃２１は左方向の入力キーであり、入力キー＃２３は右方向の入力キーである。また、上下左右のいずれの方向にも合致しない入力キーは、斜め方向にあるものと定義されてもよい。例えば、入力キー＃２２を基準キーとしたとき、入力キー＃１１は左斜め上方向の入力キーであり、入力キー＃１３は右斜め上方向の入力キーである。 In the keyboard layout information 121, input keys (for example, input keys # 11, # 22, and # 33) arranged from the upper left to the lower right on the keyboard 102 may be set in the vertical direction.
The key arrangement information 121 defines the direction in which the input keys around each reference key are located from the reference key when each input key of the keyboard 102 is used as a reference key. For example, in FIG. 4, when the input key # 22 is a reference key, the input key # 12 is an upward input key, the input key # 32 is a downward input key, and the input key # 21 is a leftward key. The input key # 23 is a right direction input key. An input key that does not match any of the up, down, left, and right directions may be defined as being in an oblique direction. For example, when the input key # 22 is a reference key, the input key # 11 is an input key in the upper left direction, and the input key # 13 is an input key in the upper right direction.
　そして、キー配列情報１２１において定義される、基準キーからの方向は、移動方向判定部１３０が判定する移動方向に対応する。具体的には、移動方向判定部１３０は、押下される入力キーが変更されたとき、キー配列情報１２１を参照して、変更前の入力キーを基準キーとした場合における変更後の入力キーの方向を判別し、判別した方向をマウスカーソルの移動方向とする。 The direction from the reference key defined in the key arrangement information 121 corresponds to the movement direction determined by the movement direction determination unit 130. Specifically, when the input key to be pressed is changed, the movement direction determination unit 130 refers to the key arrangement information 121 and determines the input key after the change when the input key before the change is the reference key. The direction is determined, and the determined direction is set as the moving direction of the mouse cursor.
　すなわち、キー配列情報１２１は、次に押下される入力キー（変更後の入力キー）の位置とマウスカーソルの移動方向とを対応付けた対応情報が、キーボード１０２が有する入力キー（変更前の入力キー）毎に登録されている情報である。そして、移動方向判定部１３０は、押下される入力キーが変更されたとき、キー配列情報１２１から、変更前の入力キーに対応する対応情報を読み出して、変更後の入力キーに対応付けられた移動方向を判定する。 In other words, the key arrangement information 121 includes the input key (input before change) that the keyboard 102 has associating information that associates the position of the input key to be pressed next (input key after change) with the moving direction of the mouse cursor. Information registered for each key. Then, when the input key to be pressed is changed, the movement direction determination unit 130 reads the correspondence information corresponding to the input key before the change from the key arrangement information 121 and associates it with the input key after the change. Determine the direction of movement.
　なお、キー配列情報１２１は、変更後の入力キーの位置とマウスカーソルの移動方向とを対応付けた対応情報が、キーボード１０２が有する入力キー毎に個別のテーブル情報に登録された情報であってもよい。この場合、各方向と周囲の入力キーとの対応付けの自由度を高めることができる。例えば、図４の入力キー＃２３に対応するテーブル情報においては、入力キー＃１２，＃１３の両方を上方向に対応付ける一方、入力キー＃２２に対応するテーブル情報においては、入力キー＃１２のみを上方向に対応付けることができる。 The key arrangement information 121 is information in which correspondence information in which the position of the input key after the change is associated with the moving direction of the mouse cursor is registered in individual table information for each input key of the keyboard 102. Also good. In this case, the degree of freedom in associating each direction with surrounding input keys can be increased. For example, in the table information corresponding to the input key # 23 in FIG. 4, both the input keys # 12 and # 13 are associated in the upward direction, while in the table information corresponding to the input key # 22, only the input key # 12 is associated. Can be associated with the upward direction.
　次に、コンピュータ１００において、キーボード１０２の操作に対応するマウスカーソルの表示位置の移動例について説明する。
　図５は、マウスカーソルの表示位置の制御例を示す第１の図である。図５では、マウスカーソル１０１ａがディスプレイ１０１の（Ｐ１１）の位置に表示されているときに、入力キー＃２１→入力キー＃２２→入力キー＃２３の順に入力キーが押下された場合の、マウスカーソル１０１ａの表示位置について説明する。 Next, an example of moving the display position of the mouse cursor corresponding to the operation of the keyboard 102 in the computer 100 will be described.
FIG. 5 is a first diagram illustrating a control example of the display position of the mouse cursor. In FIG. 5, when the mouse cursor 101a is displayed at the position (P11) on the display 101, the mouse when the input keys are pressed in the order of input key # 21 → input key # 22 → input key # 23. The display position of the cursor 101a will be described.
　まず、入力キー＃２１が押下される。このとき、変更前の入力キーが存在しない。そのため、マウスカーソル１０１ａの表示位置の移動方向は、移動方向判定部１３０により判定されない。マウスカーソル１０１ａの表示位置は、ディスプレイ１０１の（Ｐ１１）のままである。 First, input key # 21 is pressed. At this time, there is no input key before the change. Therefore, the movement direction determination unit 130 does not determine the movement direction of the display position of the mouse cursor 101a. The display position of the mouse cursor 101a remains (P11) on the display 101.
　次に、押下される入力キーが入力キー＃２２に変更される。このとき、キー配列情報１２１（図４を参照）において、変更後の入力キー＃２２は、変更前の入力キー＃２１の右方向に対応付けられている。そのため、マウスカーソル１０１ａの移動方向は、移動方向判定部１３０により「右」と判定される。また、入力キー＃２２が押下された時点では、マウスカーソル１０１ａの表示位置は移動していない。この場合、マウスカーソル１０１ａの表示位置は、マウスカーソル制御部１４０によりディスプレイ１０１の（Ｐ１１）から右方向に移動する。 Next, the input key to be pressed is changed to input key # 22. At this time, in the key arrangement information 121 (see FIG. 4), the input key # 22 after the change is associated with the right direction of the input key # 21 before the change. Therefore, the movement direction of the mouse cursor 101a is determined to be “right” by the movement direction determination unit 130. Further, when the input key # 22 is pressed, the display position of the mouse cursor 101a is not moved. In this case, the display position of the mouse cursor 101a is moved to the right from (P11) of the display 101 by the mouse cursor control unit 140.
　更に、マウスカーソル１０１ａの表示位置がディスプレイ１０１の（Ｐ１２）上を移動中に、押下される入力キーが入力キー＃２３に変更される。このとき、キー配列情報１２１（図４を参照）において、変更後の入力キー＃２３は、変更前の入力キー＃２２の右方向に対応付けられている。そのため、マウスカーソル１０１ａの移動方向は、移動方向判定部１３０により「右」と判定される。また、移動中であるマウスカーソル１０１ａの表示位置の移動方向は右方向であり、移動方向判定部１３０により判定された移動方向と同じである。この場合、マウスカーソル制御部１４０により、マウスカーソル１０１ａの移動速度が増加される。マウスカーソル１０１ａの表示位置は、ディスプレイ１０１における（Ｐ１２）から増加された移動速度で右方向に移動している状態となる。 Furthermore, the input key that is pressed while the display position of the mouse cursor 101a is moving on (P12) of the display 101 is changed to the input key # 23. At this time, in the key arrangement information 121 (see FIG. 4), the input key # 23 after the change is associated with the right direction of the input key # 22 before the change. Therefore, the movement direction of the mouse cursor 101a is determined to be “right” by the movement direction determination unit 130. The moving direction of the display position of the moving mouse cursor 101 a is the right direction, which is the same as the moving direction determined by the moving direction determination unit 130. In this case, the mouse cursor control unit 140 increases the moving speed of the mouse cursor 101a. The display position of the mouse cursor 101a is moving to the right at a moving speed increased from (P12) on the display 101.
　そして、マウスカーソル１０１ａの表示位置がディスプレイ１０１の（Ｐ１３）上を移動中にユーザが入力キー＃２３から指を離し、入力キー＃２３の押下された状態が解除されたとき、マウスカーソル１０１ａの表示位置は、ディスプレイ１０１における（Ｐ１３）の位置に停止する。 Then, when the display position of the mouse cursor 101a moves on (P13) of the display 101, the user releases the input key # 23, and when the pressed state of the input key # 23 is released, the mouse cursor 101a is moved. The display position stops at the position (P13) on the display 101.
　このように、コンピュータ１００において、移動方向判定部１３０により判定されたマウスカーソル１０１ａの移動方向が、現在のマウスカーソル１０１ａの移動方向と同じ場合は、マウスカーソル１０１ａの表示位置の移動速度が増加する。これにより、コンピュータ１００のユーザは、押下する入力キーを連続して変更するという簡単な操作により、マウスカーソル１０１ａの移動方向または移動速度を変化させることができる。 Thus, in the computer 100, when the movement direction of the mouse cursor 101a determined by the movement direction determination unit 130 is the same as the current movement direction of the mouse cursor 101a, the movement speed of the display position of the mouse cursor 101a increases. . Thereby, the user of the computer 100 can change the moving direction or moving speed of the mouse cursor 101a by a simple operation of continuously changing the input key to be pressed.
　図６は、マウスカーソルの表示位置の制御例を示す第２の図である。ここでは、マウスカーソル１０１ａがディスプレイ１０１の（Ｐ１１）に表示されているときに、入力キー＃２１→入力キー＃２２→入力キー＃１２の順に入力キーが押下された場合の、マウスカーソル１０１ａの表示位置について説明する。入力キー＃２２が押下されたときまでのマウスカーソル１０１ａの表示位置については、図５と同様のため、説明を省略する。 FIG. 6 is a second diagram showing a control example of the display position of the mouse cursor. Here, when the mouse cursor 101a is displayed on (P11) of the display 101, when the input key is pressed in the order of input key # 21 → input key # 22 → input key # 12, The display position will be described. The display position of the mouse cursor 101a until the input key # 22 is pressed is the same as in FIG.
　マウスカーソル１０１ａの表示位置がディスプレイ１０１の（Ｐ１２）上を移動中に、押下される入力キーが入力キー＃２２から入力キー＃１２に変更される。このとき、キー配列情報１２１（図４を参照）において、変更後の入力キー＃１２は、変更前の入力キー＃２２の上方向に対応付けられている。そのため、マウスカーソル１０１ａの移動方向は、移動方向判定部１３０により「上」と判定される。また、移動中であるマウスカーソル１０１ａの表示位置の移動方向は右方向であり、移動方向判定部１３０により判定された移動方向と異なる。この場合、マウスカーソル制御部１４０によりマウスカーソル１０１ａの移動方向が上方向に変更され、マウスカーソル１０１ａの表示位置は、ディスプレイ１０１における（Ｐ１２）から上方向に移動している状態となる。 When the display position of the mouse cursor 101a is moving on (P12) of the display 101, the input key to be pressed is changed from the input key # 22 to the input key # 12. At this time, in the key arrangement information 121 (see FIG. 4), the input key # 12 after the change is associated with the upward direction of the input key # 22 before the change. Therefore, the movement direction of the mouse cursor 101a is determined to be “up” by the movement direction determination unit 130. Further, the moving direction of the display position of the moving mouse cursor 101 a is the right direction, which is different from the moving direction determined by the moving direction determination unit 130. In this case, the movement direction of the mouse cursor 101a is changed upward by the mouse cursor control unit 140, and the display position of the mouse cursor 101a is moving upward from (P12) on the display 101.
　そして、マウスカーソル１０１ａの表示位置がディスプレイ１０１の（Ｐ１４）上を移動中にユーザが入力キー＃１２から指を離したとき、マウスカーソル１０１ａの表示位置は、ディスプレイ１０１における（Ｐ１４）の位置に停止する。 Then, when the user releases the input key # 12 while the display position of the mouse cursor 101a is moving on (P14) of the display 101, the display position of the mouse cursor 101a is at the position (P14) on the display 101. Stop.
　このように、コンピュータ１００において、移動方向判定部１３０により判定されたマウスカーソル１０１ａの移動方向が、現在の移動方向と異なる場合は、マウスカーソル１０１ａの表示位置の移動方向が変更される。 As described above, in the computer 100, when the movement direction of the mouse cursor 101a determined by the movement direction determination unit 130 is different from the current movement direction, the movement direction of the display position of the mouse cursor 101a is changed.
　図７は、マウスカーソルの表示位置の制御例を示す第３の図である。ここでは、ディスプレイ１０１に表示されるマウスカーソル１０１ａがディスプレイ１０１の（Ｐ１１）に表示されているときに、入力キー＃３２→入力キー＃３３→入力キー＃２３の順に入力キーが押下された場合の、マウスカーソル１０１ａの表示位置について説明する。ただし、入力キー＃３３は、入力キー＃３２から入力キー＃２３へ押下される入力キーを変更する際に触れられた程度であり、入力キー＃３３の押下された時間は、コンピュータ１００に設定されている押下されたとみなされる閾値の時間より短いものとする。入力キー＃３２が押下されたときのマウスカーソル１０１ａの表示位置については、図５における入力キー＃２１が押下されたときと同様のため、説明を省略する。 FIG. 7 is a third diagram showing a control example of the display position of the mouse cursor. Here, when the mouse cursor 101a displayed on the display 101 is displayed on (P11) of the display 101, the input keys are pressed in the order of input key # 32 → input key # 33 → input key # 23. The display position of the mouse cursor 101a will be described. However, the input key # 33 is only touched when the input key pressed from the input key # 32 to the input key # 23 is changed, and the time during which the input key # 33 is pressed is set in the computer 100. It is assumed that it is shorter than the threshold time that is considered to be pressed. Since the display position of the mouse cursor 101a when the input key # 32 is pressed is the same as when the input key # 21 in FIG. 5 is pressed, the description thereof is omitted.
　押下される入力キーが、入力キー＃３２から入力キー＃３３に変更される。このとき、入力キー＃３３は、閾値以上の時間押下されていないため、押下したとみなされない。そのため、マウスカーソル１０１ａの表示位置の移動方向は、マウスカーソル制御部１４０により判定されない。マウスカーソル１０１ａの表示位置は、ディスプレイ１０１の（Ｐ１１）のままである。 The input key to be pressed is changed from the input key # 32 to the input key # 33. At this time, since the input key # 33 has not been pressed for a time equal to or greater than the threshold, it is not considered to have been pressed. Therefore, the movement direction of the display position of the mouse cursor 101a is not determined by the mouse cursor control unit 140. The display position of the mouse cursor 101a remains (P11) on the display 101.
　次に、入力キー＃２３が押下される。このとき、キー配列情報１２１（図４を参照）において、変更後の入力キー＃２３は、変更前の入力キー＃３２の右斜め上方向に対応付けられている。そのため、マウスカーソル１０１ａの表示位置の移動方向は、移動方向判定部１３０により「右斜め上」と判定される。また、入力キー＃２３が押下された時点では、マウスカーソル１０１ａの表示位置は移動していない。そのため、マウスカーソル制御部１４０により、マウスカーソル１０１ａの表示位置は、ディスプレイ１０１における（Ｐ１１）から右斜め上方向に移動される。 Next, input key # 23 is pressed. At this time, in the key arrangement information 121 (see FIG. 4), the changed input key # 23 is associated with the upper right direction of the input key # 32 before the change. Therefore, the movement direction of the display position of the mouse cursor 101a is determined as “upward and rightward” by the movement direction determination unit 130. Further, when the input key # 23 is pressed, the display position of the mouse cursor 101a is not moved. Therefore, the mouse cursor control unit 140 moves the display position of the mouse cursor 101a in the diagonally upper right direction from (P11) on the display 101.
　そして、マウスカーソル１０１ａの表示位置がディスプレイ１０１の（Ｐ１５）上を移動中にユーザが入力キー＃２３から指を離したとき、マウスカーソル１０１ａの表示位置は、ディスプレイ１０１における（Ｐ１５）の位置に停止する。 When the user releases the input key # 23 while the display position of the mouse cursor 101a is moving on (P15) of the display 101, the display position of the mouse cursor 101a is at the position (P15) on the display 101. Stop.
　このように、コンピュータ１００において、入力キーの押下された時間が閾値未満の場合、その入力キーは押下していないとみなされる。
　なお、本実施の形態では、押下される入力キーが変更され、変更後の入力キーがキー配列情報１２１において斜め方向に対応付けられていた場合には、マウスカーソルの移動方向は一律に４５°の方向とされるものとする。例えば、図４の例において、入力キー＃３１を基準キーとした場合、入力キー＃１２，＃１３，＃２２，＃２３はいずれも右斜め上方向に対応付けられている。このような状態において、入力キー＃３１が押下された状態から、入力キー＃１２，＃１３，＃２２，＃２３のどの入力キーが押下された状態に遷移しても、マウスカーソルの移動方向は右斜め上４５°に設定される。 As described above, in the computer 100, when the time when the input key is pressed is less than the threshold, it is considered that the input key is not pressed.
In the present embodiment, when the input key to be pressed is changed and the changed input key is associated with the diagonal direction in the key arrangement information 121, the moving direction of the mouse cursor is uniformly 45 °. The direction shall be For example, in the example of FIG. 4, when the input key # 31 is used as a reference key, the input keys # 12, # 13, # 22, and # 23 are all associated with the upper right direction. In such a state, regardless of which input key # 12, # 13, # 22, or # 23 is pressed from the state in which the input key # 31 is pressed, the moving direction of the mouse cursor Is set to 45 ° diagonally upward to the right.
　ただし、斜め方向に対応付けられた入力キーの位置に応じて、マウスカーソルの移動角度がより細かく定義されてもよい。例えば、入力キー＃３１の次に入力キー＃２２が押下された場合には、マウスカーソルの移動方向を右斜め上４５°とする。また、入力キー＃３１の次に入力キー＃１２が押下された場合には、マウスカーソルの移動方向を右斜め上６０°とする。更に、入力キー＃３１の次に入力キー＃２３が押下された場合には、マウスカーソルの移動方向を右斜め上３０°とする。 However, the movement angle of the mouse cursor may be defined more finely according to the position of the input key associated with the diagonal direction. For example, when the input key # 22 is pressed after the input key # 31, the moving direction of the mouse cursor is set to 45 ° diagonally upward to the right. If the input key # 12 is pressed after the input key # 31, the moving direction of the mouse cursor is set to 60 ° diagonally upward to the right. Further, when the input key # 23 is pressed after the input key # 31, the moving direction of the mouse cursor is set to 30 ° diagonally upward to the right.
　図５～図７で示したように、コンピュータ１００は、キーボード１０２における、押下される入力キーの変更を検知することで、マウスカーソル１０１ａの表示位置の移動方向または移動速度を変更する。コンピュータ１００のユーザは、押下する入力キーを連続して変更するという簡単な操作により、マウスカーソル１０１ａの移動方向または移動速度を変化させることができる。 As shown in FIGS. 5 to 7, the computer 100 detects the change of the input key to be pressed on the keyboard 102, thereby changing the moving direction or moving speed of the display position of the mouse cursor 101a. The user of the computer 100 can change the moving direction or moving speed of the mouse cursor 101a by a simple operation of continuously changing the input key to be pressed.
　次に、マウスカーソル１０１ａの表示位置を制御する処理についてフローチャートを用いて説明する。図８は、カーソルの表示位置を制御する例を示すフローチャートである。
　（ステップＳ１１）移動方向判定部１３０は、キーボード１０２からの入力信号に基づき、キーボード１０２の入力キーが押下されたかを判定する。キーボード１０２の入力キーが押下された場合、処理をステップＳ１２へ進める。キーボード１０２の入力キーが押下されていない場合、例えば一定時間後にステップＳ１１が実行される。 Next, processing for controlling the display position of the mouse cursor 101a will be described using a flowchart. FIG. 8 is a flowchart illustrating an example of controlling the display position of the cursor.
(Step S <b> 11) The movement direction determination unit 130 determines whether an input key on the keyboard 102 is pressed based on an input signal from the keyboard 102. If the input key on the keyboard 102 has been pressed, the process proceeds to step S12. If the input key of the keyboard 102 is not pressed, for example, step S11 is executed after a predetermined time.
　（ステップＳ１２）移動方向判定部１３０は、押下される入力キーを示す情報を基準キーに設定する。基準キーは、コンピュータ１００が有するＲＡＭ１０４などの記憶領域に一時的に記憶する。 (Step S12) The movement direction determination unit 130 sets information indicating the input key to be pressed as a reference key. The reference key is temporarily stored in a storage area such as the RAM 104 of the computer 100.
　（ステップＳ１３）移動方向判定部１３０は、押下される入力キーが変更されたかを判定する。押下される入力キーが変更された場合、処理をステップＳ１４へ進める。押下される入力キーが変更されていない場合、処理をステップＳ１３へ進める。 (Step S13) The movement direction determination unit 130 determines whether the input key to be pressed has been changed. If the input key to be pressed is changed, the process proceeds to step S14. If the input key to be pressed has not been changed, the process proceeds to step S13.
　（ステップＳ１４）移動方向判定部１３０は、変更後の入力キーの押下された時間が閾値以上かを判定する。閾値は、コンピュータ１００が有するＲＡＭ１０４などの記憶領域に予め記憶されている。変更後の入力キーの押下された時間が閾値以上の場合、処理をステップＳ１５へ進める。変更後の入力キーの押下された時間が閾値未満の場合、変更後の入力キーは押下されていないとみなされ、処理をステップＳ１３へ進める。 (Step S14) The movement direction determination unit 130 determines whether or not the time when the input key after the change is pressed is equal to or greater than a threshold value. The threshold value is stored in advance in a storage area such as the RAM 104 included in the computer 100. If the time when the input key after the change is pressed is equal to or greater than the threshold, the process proceeds to step S15. If the time when the input key after the change is pressed is less than the threshold, it is considered that the input key after the change is not pressed, and the process proceeds to step S13.
　（ステップＳ１５）移動方向判定部１３０は、基準キーと変更後の入力キーとの位置関係を判定し、判定した位置関係を基に、マウスカーソル１０１ａの表示位置の移動方向や移動速度を設定する。詳細は後述する（図９を参照）。移動方向および移動速度の設定情報は、コンピュータ１００が有するＲＡＭ１０４などの記憶領域に記憶される。 (Step S15) The moving direction determination unit 130 determines the positional relationship between the reference key and the changed input key, and sets the moving direction and moving speed of the display position of the mouse cursor 101a based on the determined positional relationship. . Details will be described later (see FIG. 9). The setting information of the moving direction and moving speed is stored in a storage area such as the RAM 104 of the computer 100.
　（ステップＳ１６）マウスカーソル制御部１４０は、ステップＳ１５で設定した移動方向に、設定した移動速度分マウスカーソル１０１ａの表示位置を移動させる。
　（ステップＳ１７）移動方向判定部１３０は、押下される入力キーが変更されたかを判定する。押下される入力キーが変更された場合、処理をステップＳ１８へ進める。押下される入力キーが変更されていない場合、処理をステップＳ１９へ進める。 (Step S16) The mouse cursor control unit 140 moves the display position of the mouse cursor 101a by the set moving speed in the moving direction set in Step S15.
(Step S17) The movement direction determination unit 130 determines whether or not the input key to be pressed has been changed. If the input key to be pressed is changed, the process proceeds to step S18. If the input key to be pressed has not been changed, the process proceeds to step S19.
　（ステップＳ１８）移動方向判定部１３０は、変更後の入力キーの押下された時間が閾値以上かを判定する。この閾値は、ステップＳ１４で使用される閾値と同じ値であってよい。変更後の入力キーの押下された時間が閾値以上の場合、処理をステップＳ１５へ進める。変更後の入力キーの押下された時間が閾値未満の場合、処理をステップＳ１６へ進める。 (Step S18) The movement direction determination unit 130 determines whether or not the time when the input key after the change is pressed is equal to or greater than a threshold value. This threshold value may be the same value as the threshold value used in step S14. If the time when the input key after the change is pressed is equal to or greater than the threshold, the process proceeds to step S15. If the changed input key has been pressed for less than the threshold, the process proceeds to step S16.
　（ステップＳ１９）移動方向判定部１３０は、キーボード１０２からの入力信号の有無により、キーボード１０２のいずれの入力キーも押下されていないキー離れの状態か判定する。キー離れの状態である場合、処理をステップＳ２０へ進める。キー離れの状態でない場合、処理をステップＳ１６へ進める。 (Step S19) The moving direction determination unit 130 determines whether any input key of the keyboard 102 is not pressed, based on the presence or absence of an input signal from the keyboard 102. If the key is off, the process proceeds to step S20. If not, the process proceeds to step S16.
　（ステップＳ２０）移動方向判定部１３０は、キー離れの状態の時間が閾値以上かを判定する。閾値は、コンピュータ１００が有するＲＡＭ１０４などの記憶領域に予め記憶されている。キー離れの状態の時間が閾値以上の場合、マウスカーソル１０１ａの表示位置における移動方向の設定情報をクリアし、処理を終了する。キー離れの状態の時間が閾値未満の場合、処理をステップＳ１６へ進める。 (Step S20) The movement direction determination unit 130 determines whether the time of the key separation state is equal to or greater than a threshold value. The threshold value is stored in advance in a storage area such as the RAM 104 included in the computer 100. When the time of the key separation state is equal to or greater than the threshold value, the setting information of the moving direction at the display position of the mouse cursor 101a is cleared, and the process is terminated. If the time of key separation is less than the threshold, the process proceeds to step S16.
　このステップＳ２０では、キー離れの状態の時間が閾値未満の場合には、キー離れと判定されなくなる。これにより、例えば、ユーザがある入力キーを押下した状態から他の入力キーを連続して押下する際に、瞬間的にいずれの入力キーが押下されていない状態が発生した場合でも、キー離れの発生とは判定されずに、押下される入力キーが他の入力キーに変更されたと判定されるようになる。 In this step S20, when the time of the key separation state is less than the threshold value, it is not determined that the key separation has occurred. As a result, for example, when a user continuously presses another input key from a state in which one input key is pressed, even if a state in which any input key is not pressed instantaneously occurs, It is determined that the input key to be pressed has been changed to another input key without being determined to have occurred.
　図９は、カーソルの移動に関する情報を更新する例を示すフローチャートである。図９のフローチャートが示す処理は、上記のステップＳ１５において実行される。
　（ステップＳ１５１）移動方向判定部１３０は、変更後の押下される入力キーを確認する。 FIG. 9 is a flowchart illustrating an example of updating information regarding cursor movement. The process shown in the flowchart of FIG. 9 is executed in step S15 described above.
(Step S151) The movement direction determination unit 130 confirms the input key to be pressed after the change.
　（ステップＳ１５２）移動方向判定部１３０は、キー配列情報１２１に基づいた基準キーと変更後の入力キーとの位置関係により、マウスカーソル１０１ａの表示位置の移動方向を判定する。 (Step S152) The movement direction determination unit 130 determines the movement direction of the display position of the mouse cursor 101a based on the positional relationship between the reference key based on the key arrangement information 121 and the changed input key.
　（ステップＳ１５３）マウスカーソル制御部１４０は、マウスカーソル１０１ａの表示位置が移動中であるかを判定する。マウスカーソル１０１ａの表示位置が移動中であるかは、例えば、マウスカーソル１０１ａの表示位置の移動方向を示す情報への設定の有無により判断できる。マウスカーソル１０１ａの表示位置が移動中である場合、処理をステップＳ１５４へ進める。マウスカーソル１０１ａの表示位置が移動中でない場合、処理をステップＳ１５６へ進める。 (Step S153) The mouse cursor control unit 140 determines whether the display position of the mouse cursor 101a is moving. Whether the display position of the mouse cursor 101a is moving can be determined by, for example, whether or not the information indicating the moving direction of the display position of the mouse cursor 101a is set. If the display position of the mouse cursor 101a is moving, the process proceeds to step S154. If the display position of the mouse cursor 101a is not moving, the process proceeds to step S156.
　（ステップＳ１５４）マウスカーソル制御部１４０は、マウスカーソル１０１ａの表示位置の移動方向が変更されたか判定する。移動方向が変更されたかは、ステップＳ１５２で判定された移動方向と、移動中の移動方向とが異なるかにより判定できる。マウスカーソル１０１ａの表示位置の移動方向が変更された場合、処理をステップＳ１５６へ進める。
マウスカーソル１０１ａの表示位置の移動方向が変更されていない場合、処理をステップＳ１５５へ進める。 (Step S154) The mouse cursor control unit 140 determines whether the moving direction of the display position of the mouse cursor 101a has been changed. Whether the moving direction has been changed can be determined based on whether the moving direction determined in step S152 is different from the moving direction during movement. If the moving direction of the display position of the mouse cursor 101a has been changed, the process proceeds to step S156.
If the moving direction of the display position of the mouse cursor 101a has not been changed, the process proceeds to step S155.
　（ステップＳ１５５）マウスカーソル制御部１４０は、マウスカーソル１０１ａの表示位置の移動速度を増加させる。マウスカーソル制御部１４０は、例えば、現在設定されている移動速度に、予め決められた速度加算値を加算する。 (Step S155) The mouse cursor control unit 140 increases the moving speed of the display position of the mouse cursor 101a. For example, the mouse cursor control unit 140 adds a predetermined speed addition value to the currently set moving speed.
　（ステップＳ１５６）マウスカーソル制御部１４０は、マウスカーソル１０１ａの表示位置の移動方向を設定する。
　（ステップＳ１５７）マウスカーソル制御部１４０は、マウスカーソル１０１ａの表示位置の移動速度に、予め決められた初期値を設定する。 (Step S156) The mouse cursor control unit 140 sets the moving direction of the display position of the mouse cursor 101a.
(Step S157) The mouse cursor control unit 140 sets a predetermined initial value for the moving speed of the display position of the mouse cursor 101a.
　（ステップＳ１５８）移動方向判定部１３０は、基準キーを、変更後の入力キーを示す情報に更新する。
　第２の実施の形態によれば、押下される入力キーが変更される毎に、変更前後の入力キーの位置関係から、マウスカーソル１０１ａの表示位置の移動方向を判定する。判定した移動方向と、移動中であるマウスカーソル１０１ａの表示位置の移動方向とが同じであれば、移動速度を変更する。判定した移動方向と、移動中であるマウスカーソル１０１ａの表示位置の移動方向とが異なる場合、移動方向を変更する。これにより、連続的にマウスカーソル１０１ａの表示速度や移動方向を変更させることができる。よって、指示画像の表示位置の移動速度を変更させるたびに、２回のキー入力操作を行う方法と比べ、操作性が向上する。 (Step S158) The movement direction determination unit 130 updates the reference key to information indicating the changed input key.
According to the second embodiment, every time the input key to be pressed is changed, the moving direction of the display position of the mouse cursor 101a is determined from the positional relationship of the input keys before and after the change. If the determined moving direction is the same as the moving direction of the display position of the moving mouse cursor 101a, the moving speed is changed. When the determined moving direction is different from the moving direction of the display position of the moving mouse cursor 101a, the moving direction is changed. Thereby, the display speed and moving direction of the mouse cursor 101a can be changed continuously. Therefore, the operability is improved as compared with the method in which the key input operation is performed twice each time the moving speed of the display position of the instruction image is changed.
　また、入力キーが押下され続けた時間が閾値未満の場合、入力キーが押下されたとみなさないようにする。これにより、斜め方向にマウスカーソル１０１ａの表示位置を移動させるために、押下する入力キーを斜め方向に移動する途中に存在する入力キーに触れても、触れた入力キーにより押下される入力キーが変更されたとみなされない。よって、斜め方向にマウスカーソル１０１ａの表示位置を移動させる場合も、操作性を維持できる。 Also, if the time that the input key is continuously pressed is less than the threshold, it is not considered that the input key has been pressed. Thereby, in order to move the display position of the mouse cursor 101a in the diagonal direction, even if the input key to be pressed touches an input key existing in the middle of moving in the diagonal direction, the input key pressed by the touched input key is It is not considered changed. Therefore, operability can be maintained even when the display position of the mouse cursor 101a is moved in an oblique direction.
　なお、前述のように、第１の実施の形態の情報処理は、情報処理装置１０にプログラムを実行させることで実現でき、第２の実施の形態の情報処理は、コンピュータ１００にプログラムを実行させることで実現できる。このようなプログラムは、コンピュータ読み取り可能な記録媒体（例えば、記録媒体２１）に記録しておくことができる。記録媒体としては、例えば、磁気ディスク、光ディスク、光磁気ディスク、半導体メモリなどを使用できる。磁気ディスクには、ＦＤおよびＨＤＤが含まれる。光ディスクには、ＣＤ、ＣＤ－Ｒ（Recordable）／ＲＷ（Rewritable）、ＤＶＤおよびＤＶＤ－Ｒ／ＲＷが含まれる。 As described above, the information processing according to the first embodiment can be realized by causing the information processing apparatus 10 to execute a program, and the information processing according to the second embodiment causes the computer 100 to execute a program. This can be achieved. Such a program can be recorded on a computer-readable recording medium (for example, the recording medium 21). As the recording medium, for example, a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like can be used. Magnetic disks include FD and HDD. Optical disks include CD, CD-R (Recordable) / RW (Rewritable), DVD, and DVD-R / RW.
　プログラムを流通させる場合、例えば、当該プログラムを記録した可搬記録媒体が提供される。また、プログラムを他のコンピュータの記憶装置に格納しておき、ネットワーク３０経由でプログラムを配布することもできる。コンピュータは、例えば、可搬記録媒体に記録されたプログラムまたは他のコンピュータから受信したプログラムを、記憶装置（例えば、ＨＤＤ１０５）に格納し、当該記憶装置からプログラムを読み込んで実行する。ただし、可搬記録媒体から読み込んだプログラムを直接実行してもよく、他のコンピュータからネットワーク３０を介して受信したプログラムを直接実行してもよい。また、上記の情報処理の少なくとも一部を、ＤＳＰ、ＡＳＩＣ、ＰＬＤ（Programmable Logic Device）などの電子回路で実現することも可能である。 When distributing the program, for example, a portable recording medium on which the program is recorded is provided. It is also possible to store the program in a storage device of another computer and distribute the program via the network 30. The computer stores, for example, a program recorded on a portable recording medium or a program received from another computer in a storage device (for example, the HDD 105), and reads and executes the program from the storage device. However, a program read from a portable recording medium may be directly executed, or a program received from another computer via the network 30 may be directly executed. In addition, at least a part of the information processing described above can be realized by an electronic circuit such as a DSP, an ASIC, or a PLD (Programmable Logic Device).
