Description

情報処理装置、情報処理方法、およびプログラムInformation processing apparatus, information processing method, and program
　本発明は、情報処理装置、情報処理方法、およびプログラムに関する。 The present invention relates to an information processing apparatus, an information processing method, and a program.
　近年、スマートフォンやタブレット端末のような情報処理装置が普及している。このような情報処理装置は、通常、表示パネルに重畳したタッチセンサを搭載しており、ユーザがこのタッチセンサの操作面上に操作体である指を接触または近接させた位置に基づいて入力操作を認識する。以下、接触または近接させることをタッチと称し、タッチした位置をタッチ位置と称する。 In recent years, information processing devices such as smartphones and tablet terminals have become widespread. Such an information processing apparatus usually includes a touch sensor superimposed on a display panel, and an input operation is performed based on a position where a user touches or approaches a finger as an operating body on the operation surface of the touch sensor. Recognize Hereinafter, contacting or approaching is referred to as touch, and a touched position is referred to as a touch position.
　このような情報処理装置は、例えばタッチ位置の軌跡（以下、操作軌跡と称する。）が予め定められたパターンを描く入力操作を認識した場合に、その入力操作に応じた所定の処理を実行することがある。例えばこのような入力操作の一例としては、操作面にタッチしたまま指を動かすドラッグ操作、および操作面をタッチした後に素早くスライドしてから指をはじくように離すフリック操作などが挙げられる。ユーザがこのような入力操作を行うことで描かれる操作軌跡は、ユーザ毎に特徴がある。例えば横方向のドラッグ操作を行うとき、あるユーザはいつも右斜め上方向に向かう軌跡を描いてしまう場合がある。この場合、横方向の直線を描く理想的な軌跡と実際の軌跡とがずれてしまうため、ユーザの入力操作が意図した通りに認識されないことがある。 For example, when such an information processing apparatus recognizes an input operation in which a touch position locus (hereinafter referred to as an operation locus) draws a predetermined pattern, a predetermined process corresponding to the input operation is executed. Sometimes. For example, examples of such an input operation include a drag operation for moving a finger while touching the operation surface, and a flick operation for quickly sliding after touching the operation surface and releasing the finger. The operation trajectory drawn by the user performing such an input operation has a feature for each user. For example, when performing a drag operation in the horizontal direction, a user may always draw a trajectory that goes diagonally upward to the right. In this case, the ideal trajectory that draws a straight line in the horizontal direction deviates from the actual trajectory, and the user's input operation may not be recognized as intended.
　入力操作の認識精度を改善するための技術としては、特許文献１および２に記載の技術がある。 There are techniques described in Patent Documents 1 and 2 as techniques for improving the recognition accuracy of input operations.
　特許文献１には、入力操作の校正用のアプリケーションを起動した状態で、スティックポインタを用いた入力操作に応じたポインティング位置の軌跡である操作軌跡に関する特徴データを収集しておき、この収集した特徴データに基づいて、入力されたポインティング位置を補正する校正装置が開示されている。 In Patent Document 1, feature data relating to an operation locus, which is a locus of a pointing position corresponding to an input operation using a stick pointer, is collected in a state where an application for calibrating an input operation is activated. A calibration device that corrects an input pointing position based on data is disclosed.
　また特許文献２には、校正用のアプリケーションを起動した状態で、ユーザがトラックボールを回転する入力操作を行った場合、その入力操作に応じて変化するポインティング位置の操作軌跡に関する特徴データを収集し、この操作軌跡の特徴に基づいて、入力された位置を補正する補正装置が開示されている。 Further, in Patent Document 2, when a user performs an input operation for rotating a trackball in a state where a calibration application is activated, feature data relating to an operation locus of a pointing position that changes according to the input operation is collected. A correction device that corrects an input position based on the characteristics of the operation locus is disclosed.

It was necessary to perform an input operation to collect the characteristics of For this reason, the user has to perform an input operation only to collect the characteristics of the operation trajectory, and there is a problem that the user has a lot of trouble.

　以下、本発明の実施形態について図面を参照して説明する。なお、以下の説明では、同じ機能を有するものには同じ符号を付け、その説明を省略する場合がある。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, components having the same function may be denoted by the same reference numerals and description thereof may be omitted.
　（第１の実施形態）
　まず本発明の第１の実施形態について説明する。図１は、本発明の第１の実施形態にかかる情報処理装置の外観図である。図１に示す情報処理装置１００は、表示装置１１と、表示装置１１に重畳されたタッチセンサ１２とを有する。表示装置１１およびタッチセンサ１２が重畳されたパネルの表面は、図示しないガラス材料などの保護部材で保護されている。そしてユーザが保護部材に対して操作体を接触または近接させると、この操作体の位置をタッチセンサ１２が検知する。 (First embodiment)
First, a first embodiment of the present invention will be described. FIG. 1 is an external view of an information processing apparatus according to the first embodiment of the present invention. An information processing apparatus 100 illustrated in FIG. 1 includes a display device 11 and a touch sensor 12 superimposed on the display device 11. The surface of the panel on which the display device 11 and the touch sensor 12 are superimposed is protected by a protective member such as a glass material (not shown). When the user brings the operating body into contact with or close to the protection member, the touch sensor 12 detects the position of the operating body.
　なお以下の説明において、操作体はユーザの指とするが、操作体は指以外の物体であってもよい。例えば操作体は、ユーザの身体のうち指以外の部位、またはスタイラスペンなどでもよい。 In the following description, the operating body is a user's finger, but the operating body may be an object other than the finger. For example, the operation body may be a part other than the finger of the user's body, or a stylus pen.
　情報処理装置１００は、例えば携帯電話、スマートフォン、ゲーム機器、ＰＣ（Ｐｅｒｓｏｎａｌ　Ｃｏｍｐｕｔｅｒ）、ＰＤＡ（Ｐｅｒｓｏｎａｌ　Ｄｉｇｉｔａｌ　Ａｓｓｉｓｔａｎｔ：携帯情報端末）、ナビゲーション装置、音楽再生装置、および映像処理装置などである。なおＰＣには、タブレット型ＰＣやノート型ＰＣなども含まれる。また映像処理装置には、カメラ、レコーダ、プレイヤなども含まれる。 The information processing apparatus 100 is, for example, a mobile phone, a smartphone, a game machine, a PC (Personal Computer), a PDA (Personal Digital Assistant), a navigation apparatus, a music playback apparatus, and a video processing apparatus. Note that the PC includes a tablet PC and a notebook PC. The video processing device also includes a camera, a recorder, a player, and the like.
　図２は、本実施形態にかかる情報処理装置の構成を示すブロック図である。図2に示すように情報処理装置１００は、表示装置１１と、タッチセンサ１２と、制御装置１４と、メモリ１３とを有する。 FIG. 2 is a block diagram showing the configuration of the information processing apparatus according to the present embodiment. As illustrated in FIG. 2, the information processing apparatus 100 includes a display device 11, a touch sensor 12, a control device 14, and a memory 13.
　表示装置１１は、表示画面を表示する。表示装置１１は、例えば液晶ディスプレイ装置や有機ＥＬ（Ｅｌｅｃｔｒｏ　Ｌｕｍｉｎｅｓｃｅｎｃｅ）ディスプレイ装置などである。 Display device 11 displays a display screen. The display device 11 is, for example, a liquid crystal display device or an organic EL (Electro Luminescence) display device.
　タッチセンサ１２は、タッチ位置を検知し、検知したタッチ位置を示す入力信号を制御装置１４に入力する。なお本実施形態において、タッチセンサ１２は、表示装置１１と重畳して設けられるため、表示装置１１の表示面はタッチセンサ１２の操作面と兼用される。タッチセンサ１２は、例えば静電容量式のタッチセンサである。またタッチセンサ１２は、抵抗膜方式、または他の方式のタッチセンサであってもよい。 The touch sensor 12 detects the touch position and inputs an input signal indicating the detected touch position to the control device 14. In the present embodiment, since the touch sensor 12 is provided so as to overlap the display device 11, the display surface of the display device 11 is also used as the operation surface of the touch sensor 12. The touch sensor 12 is a capacitive touch sensor, for example. The touch sensor 12 may be a resistive film type or other type touch sensor.
　メモリ１３は、記憶部の一例であり、制御装置１４によって読取り可能な記録媒体である。メモリ１３は、例えば制御装置１４の動作を規定するプログラムを記憶する。またメモリ１３は、タッチ位置の軌跡を補正する補正量を記憶する。 The memory 13 is an example of a storage unit, and is a recording medium that can be read by the control device 14. The memory 13 stores a program that defines the operation of the control device 14, for example. The memory 13 stores a correction amount for correcting the locus of the touch position.
　制御装置１４は、情報処理装置１００を制御し、例えばＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）である。制御装置１４は、メモリ１３に記憶されたプログラムを読み取り、このプログラムを実行することによって、表示制御部２１、軌跡出力部２２、および統括制御部２３を実現する。 The control device 14 controls the information processing device 100 and is, for example, a CPU (Central Processing Unit). The control device 14 reads the program stored in the memory 13 and executes the program, thereby realizing the display control unit 21, the locus output unit 22, and the overall control unit 23.
　表示制御部２１は、表示画面を生成し、生成した表示画面を表示装置１１に表示する。表示画面の一例としては、待ち受け状態で表示される待ち受け画面、起動するアプリケーションを選択するためのアプリケーションランチャ画面、および情報処理装置１００の機能が制限されたロック状態を解除するためのロック解除画面などが挙げられる。 The display control unit 21 generates a display screen and displays the generated display screen on the display device 11. Examples of the display screen include a standby screen displayed in a standby state, an application launcher screen for selecting an application to be activated, and an unlock screen for releasing a lock state in which the functions of the information processing apparatus 100 are restricted. Is mentioned.
　軌跡出力部２２は、タッチセンサ１２から入力された入力信号の示すタッチ位置の軌跡である操作軌跡を算出し、当該操作軌跡をメモリ１３内の補正量に基づいて補正する。以下、操作軌跡を補正した軌跡を補正軌跡と称する。このとき軌跡出力部２２は、算出した全ての操作軌跡を補正してもよいし、操作軌跡が予め定められた適用条件を満たす場合に、当該操作軌跡を補正してもよい。後者の場合、軌跡出力部２２は、操作軌跡が適用条件を満たす場合、補正軌跡を入力操作の認識に用いる軌跡である認識用軌跡として出力し、操作軌跡が適用条件を満たさない場合、操作軌跡を認識用軌跡として出力する。 The locus output unit 22 calculates an operation locus that is a locus of the touch position indicated by the input signal input from the touch sensor 12, and corrects the operation locus based on the correction amount in the memory 13. Hereinafter, a locus obtained by correcting the operation locus is referred to as a corrected locus. At this time, the trajectory output unit 22 may correct all the calculated operation trajectories, or may correct the operation trajectory when the operation trajectory satisfies a predetermined application condition. In the latter case, the trajectory output unit 22 outputs the correction trajectory as a recognition trajectory that is a trajectory used for recognition of the input operation when the operation trajectory satisfies the application condition, and the operation trajectory when the operation trajectory does not satisfy the application condition. Is output as a recognition trajectory.
　適用条件は、例えば、操作軌跡と予め定められた所定の軌跡との差異が所定の範囲内であることである。所定の軌跡は複数あってもよい。この場合、補正量および適用条件は所定の軌跡毎に設けられる。そして軌跡出力部２２は、所定の軌跡それぞれについて操作軌跡が適用条件を満たすか否かを判断する。軌跡出力部２２は、操作軌跡が少なくとも一つの適用条件を満たす場合、補正軌跡を認識用軌跡として出力し、操作軌跡が適用条件のいずれも満たさない場合、操作軌跡を認識用軌跡として出力する。なお、操作軌跡が複数の適用条件を満たす場合、軌跡出力部２２は、操作軌跡との差異が最も小さい所定の軌跡を選択し、選択された所定の軌跡の補正量に基づいて操作軌跡を補正する。 The application condition is, for example, that a difference between an operation locus and a predetermined locus is within a predetermined range. There may be a plurality of predetermined trajectories. In this case, the correction amount and the application condition are provided for each predetermined locus. The trajectory output unit 22 determines whether or not the operation trajectory satisfies the application condition for each of the predetermined trajectories. The trajectory output unit 22 outputs the correction trajectory as a recognition trajectory when the operation trajectory satisfies at least one application condition, and outputs the operation trajectory as a recognition trajectory when the operation trajectory does not satisfy any of the application conditions. When the operation locus satisfies a plurality of application conditions, the locus output unit 22 selects a predetermined locus having the smallest difference from the operation locus, and corrects the operation locus based on the correction amount of the selected predetermined locus. To do.
　統括制御部２３は、情報処理装置１００の動作を制御する制御部の一例である。 The overall control unit 23 is an example of a control unit that controls the operation of the information processing apparatus 100.
　統括制御部２３は、表示制御部２１を用いて、種々の表示画面を表示装置１１に表示する。 The overall control unit 23 uses the display control unit 21 to display various display screens on the display device 11.
　また、統括制御部２３は、軌跡出力部２２から出力された認識用軌跡に基づいて入力操作を認識し、認識した入力操作に応じた処理を実行する。例えば、統括制御部２３は、所定の表示画面が表示された状態で、認識用軌跡が所定のパターンを描く場合に、その認識用軌跡が示す入力操作に応じた特定の処理を実行する。所定の表示画面としては、上記のロック解除画面、待ち受け画面、およびアプリケーションランチャ画面などが挙げられる。例えば、アプリケーションランチャ画面が表示された状態で、入力操作としてドラッグ操作またはフリック操作を認識すると、統括制御部２３は、当該操作の方向に応じて、アプリケーションランチャ画面の表示領域を変更する。また例えば、ロック解除画面が表示された状態で、入力操作としてロック解除操作を認識すると、統括制御部２３は、ロック状態を解除する。また、所定のパターンは、所定の表示画面ごとに異なっていてもよい。 Further, the overall control unit 23 recognizes the input operation based on the recognition trajectory output from the trajectory output unit 22, and executes a process according to the recognized input operation. For example, when the recognition trajectory draws a predetermined pattern in a state where a predetermined display screen is displayed, the overall control unit 23 executes specific processing according to the input operation indicated by the recognition trajectory. Examples of the predetermined display screen include the lock release screen, the standby screen, and the application launcher screen. For example, when a drag operation or a flick operation is recognized as an input operation in a state where the application launcher screen is displayed, the overall control unit 23 changes the display area of the application launcher screen according to the direction of the operation. For example, when the unlocking operation is recognized as an input operation in a state where the unlocking screen is displayed, the overall control unit 23 releases the locking state. Further, the predetermined pattern may be different for each predetermined display screen.
　なお、所定の軌跡は、所定のパターンを描く軌跡である。所定のパターンが所定の表示画面ごとに異なる場合であっても、軌跡出力部２２は、操作軌跡を算出したときに表示されていた表示画面に関わらず、全ての所定の軌跡について、操作軌跡が適用条件を満たすか否かを判断する。 Note that the predetermined trajectory is a trajectory in which a predetermined pattern is drawn. Even when the predetermined pattern is different for each predetermined display screen, the trajectory output unit 22 has the operation trajectory for all the predetermined trajectories regardless of the display screen displayed when the operation trajectory is calculated. It is determined whether the application condition is satisfied.
　また、所定の表示画面が表示されている場合、統括制御部２３は、軌跡出力部２２が算出した操作軌跡と、所定のパターンとに基づいて、メモリ１３に記憶された補正量を調整する。より具体的には、統括制御部２３は、操作軌跡と所定のパターンとの差異に基づいて、補正量を調整する。所定の表示画面は、情報処理装置１００が起動した後、起動するアプリケーションを選択する選択操作が認識される前に表示される表示画面であることが望ましい。 Further, when the predetermined display screen is displayed, the overall control unit 23 adjusts the correction amount stored in the memory 13 based on the operation locus calculated by the locus output unit 22 and the predetermined pattern. More specifically, the overall control unit 23 adjusts the correction amount based on the difference between the operation locus and the predetermined pattern. The predetermined display screen is desirably a display screen that is displayed after the information processing apparatus 100 is started and before a selection operation for selecting an application to be started is recognized.
　次に、軌跡出力部２２の行う操作軌跡の補正、および統括制御部２３の行う入力操作の認識および補正量の調整について、具体例を挙げてより詳細に説明する。 Next, the correction of the operation trajectory performed by the trajectory output unit 22 and the recognition of the input operation performed by the overall control unit 23 and the adjustment of the correction amount will be described in more detail with specific examples.
　まず本実施形態にかかる情報処理装置が表示するロック解除画面について説明する。図３は、本実施形態にかかる情報処理装置が表示する、横方向の入力操作を受け付けるロック解除画面の一例を示す説明図である。図４は、本実施形態にかかる情報処理装置が表示する、縦方向の入力操作を受け付けるロック解除画面の一例を示す説明図である。 First, the unlock screen displayed by the information processing apparatus according to the present embodiment will be described. FIG. 3 is an explanatory diagram illustrating an example of an unlock screen that is displayed by the information processing apparatus according to the present embodiment and that accepts an input operation in the horizontal direction. FIG. 4 is an explanatory diagram illustrating an example of an unlock screen that is displayed by the information processing apparatus according to the present embodiment and that accepts an input operation in the vertical direction.
　表示制御部２１は、情報処理装置１００の機能が制限されたロック状態で、図３または図４に示すロック解除画面１０２を表示する。なお、表示制御部２１は、例えば、情報処理装置１００がロック状態で所定の操作（操作面にタッチ、またはボタンの押下）が検知された場合に、このロック解除画面１０２を表示する。 The display control unit 21 displays the unlock screen 102 shown in FIG. 3 or 4 in the locked state in which the function of the information processing apparatus 100 is limited. The display control unit 21 displays the unlock screen 102 when, for example, a predetermined operation (touch on the operation surface or button press) is detected while the information processing apparatus 100 is in the locked state.
　ロック解除画面１０２は、ロック解除アイコン２０１とスライドガイド２０２とを含む。統括制御部２３は、ロック解除アイコン２０１上にタッチ位置を検知した後、ロック解除アイコン２０１をスライドガイド２０２に沿った方向にスライドさせるドラッグ操作またはフリック操作を認識すると、ロック状態を解除する。 The unlock screen 102 includes an unlock icon 201 and a slide guide 202. When the overall control unit 23 detects a touch position on the unlock icon 201 and then recognizes a drag operation or a flick operation to slide the unlock icon 201 in the direction along the slide guide 202, the overall control unit 23 releases the locked state.
　例えば図３の例では、統括制御部２３は、ロック解除アイコン２０１Ｓ上にタッチ位置を検知した後、ロック解除アイコン２０１Ｓをスライドガイド２０２Ｓに沿って右方向にスライドさせるドラッグ操作またはフリック操作を認識すると、ロック状態を解除する。同様に図４の例では、統括制御部２３は、ロック解除アイコン２０１Ｈ上にタッチ位置を検知した後、スライドガイド２０２Ｌに沿って上方向にスライドさせるドラッグ操作またはフリック操作を認識すると、ロック状態を解除する。 For example, in the example of FIG. 3, when the overall control unit 23 detects a touch position on the unlock icon 201S, it recognizes a drag operation or a flick operation that slides the unlock icon 201S to the right along the slide guide 202S. Release the lock state. Similarly, in the example of FIG. 4, when the overall control unit 23 detects a touch position on the lock release icon 201H and then recognizes a drag operation or a flick operation that slides upward along the slide guide 202L, the overall control unit 23 changes the lock state. To release.
　図３のロック解除画面１０２Ｓが表示された状態において情報処理装置１００の行う操作軌跡の補正および入力操作の認識について、説明する。図５は、本実施形態にかかる情報処理装置が、ロック解除画面を表示した状態で行う適用条件の判断について説明するための説明図である。図６は、本実施形態にかかる情報処理装置が、ロック解除画面を表示した状態で行う操作軌跡の補正および入力操作の認識について説明するための説明図である。 The correction of the operation trajectory and the recognition of the input operation performed by the information processing apparatus 100 in a state where the lock release screen 102S of FIG. FIG. 5 is an explanatory diagram for explaining determination of application conditions performed by the information processing apparatus according to the present embodiment in a state where the unlock screen is displayed. FIG. 6 is an explanatory diagram for explaining the correction of the operation trajectory and the recognition of the input operation performed by the information processing apparatus according to the present embodiment in a state where the unlock screen is displayed.
　ここで所定のパターンを示すベクトルを基準ベクトルＶ１とし、操作軌跡を示すベクトルを操作ベクトルＶ２とする。ここで、基準ベクトルＶ１についての適用条件は、操作ベクトルＶ２と基準ベクトルＶ１との差異が所定の範囲内であることである。軌跡出力部２２は、操作ベクトルＶ２が、操作ベクトルＶ２と基準ベクトルＶ１との差異が所定の範囲内となる適用範囲２０３内であるか否かに基づいて適用条件を判断する。このため、軌跡出力部２２は、操作ベクトルＶ２が適用範囲２０３内である場合、メモリ１３に記憶された補正量を用いて、操作ベクトルＶ２を補正する。具体的には、軌跡出力部２２は、操作ベクトルＶ２と補正量を示す補正量ベクトルＶ３ｍとの差を求めることで、補正後ベクトルＶ４を求める。これにより、Ｖ４＝Ｖ２－Ｖ３ｍとなる。軌跡出力部２２は、求めた補正後ベクトルＶ４を認識用軌跡を示す認識用ベクトルとして出力する。統括制御部２３は、この補正後ベクトルＶ４に基づいて、入力操作を認識する。 Here, a vector indicating a predetermined pattern is a reference vector V1, and a vector indicating an operation locus is an operation vector V2. Here, the application condition for the reference vector V1 is that the difference between the operation vector V2 and the reference vector V1 is within a predetermined range. The trajectory output unit 22 determines the application condition based on whether or not the operation vector V2 is within the application range 203 where the difference between the operation vector V2 and the reference vector V1 is within a predetermined range. Therefore, when the operation vector V2 is within the application range 203, the trajectory output unit 22 corrects the operation vector V2 using the correction amount stored in the memory 13. Specifically, the locus output unit 22 obtains a corrected vector V4 by obtaining a difference between the operation vector V2 and a correction amount vector V3m indicating a correction amount. As a result, V4 = V2−V3m. The locus output unit 22 outputs the obtained corrected vector V4 as a recognition vector indicating a recognition locus. The overall control unit 23 recognizes the input operation based on the corrected vector V4.
　ここで補正量を示す補正量ベクトルＶ３ｍの調整について説明する。図７は、本実施形態にかかる情報処理装置がロック解除画面を表示した状態で行う補正量の調整について説明するための説明図である。統括制御部２３は、操作ベクトルＶ２と基準ベクトルＶ１との差を、基準軌跡と操作軌跡との差異を示す差異ベクトルＶ３として求める。これにより、Ｖ３＝Ｖ２－Ｖ１となる。 Here, the adjustment of the correction amount vector V3m indicating the correction amount will be described. FIG. 7 is an explanatory diagram for explaining adjustment of the correction amount performed in a state in which the information processing apparatus according to the present embodiment displays the unlock screen. The overall control unit 23 obtains a difference between the operation vector V2 and the reference vector V1 as a difference vector V3 indicating a difference between the reference locus and the operation locus. As a result, V3 = V2−V1.
　統括制御部２３は、軌跡出力部２２が操作ベクトルＶ２を算出する度に、差異ベクトルＶ３を求め、メモリ１３に記憶する。ここで記憶された順番に差異ベクトルＶ３をそれぞれ差異ベクトルＶ３１、差異ベクトルＶ３２・・・差異ベクトルＶ３ｎと称する。そして、差異ベクトルＶ３をメモリ１３に記憶するとき、統括制御部２３は、すでに差異ベクトルＶ３がメモリ１３に記憶されているか否かを判断する。 The overall control unit 23 obtains the difference vector V3 and stores it in the memory 13 every time the locus output unit 22 calculates the operation vector V2. The difference vectors V3 are referred to as difference vector V3 1 , difference vector V3 2 ... Difference vector V3 n in the order stored here. When storing the difference vector V3 in the memory 13, the overall control unit 23 determines whether or not the difference vector V3 is already stored in the memory 13.
　差異ベクトルＶ３が記憶されていない場合、メモリ１３には補正量の初期値として０が記憶されている。統括制御部２３は、このとき差異ベクトルＶ３１を補正量としてメモリ１３に記憶する。 When the difference vector V3 is not stored, 0 is stored in the memory 13 as the initial value of the correction amount. The central control unit 23 stores the difference vector V3 1 In this case the memory 13 as the correction amount.
　またすでに差異ベクトルＶ３が記憶されている場合、統括制御部２３は、すでに記憶された差異ベクトルＶ３１～Ｖ３ｎ－１と、現時点において記憶した差異ベクトルＶ３ｎとを合わせた複数の差異ベクトルＶ３の平均である平均ベクトルＶ３ｍを求める。ここで統括制御部２３は、所定個数Ｎ以上の差異ベクトルＶ３が求められた後は、新しく求められた方からＮ個の差異ベクトルＶ３を用いて平均ベクトルＶ３ｍを求める。統括制御部２３は、求めた平均ベクトルＶ３ｍを補正量としてメモリ１３に記憶する。なお平均ベクトルＶ３ｍは、補正量を示す補正量ベクトルである。 When the difference vector V3 is already stored, the overall control unit 23 adds a plurality of difference vectors V3, which is a combination of the already stored difference vectors V3 1 to V3 n−1 and the currently stored difference vector V3 n. An average vector V3m, which is the average of, is obtained. Here, after obtaining the difference vector V3 of the predetermined number N or more, the overall control unit 23 obtains the average vector V3m using N difference vectors V3 from the newly obtained one. The overall control unit 23 stores the obtained average vector V3m in the memory 13 as a correction amount. The average vector V3m is a correction amount vector indicating a correction amount.
　なお、ここではロック解除画面１０２Ｓにて、操作軌跡の補正を行う場合について説明したが、本発明はかかる例に限定されない。他の表示画面においても、平均ベクトルＶ３ｍを用いて操作軌跡の補正を行い、補正後ベクトルＶ４を用いて、入力操作を認識することができる。 In addition, although the case where the operation locus is corrected on the unlock screen 102S has been described here, the present invention is not limited to such an example. On other display screens, the operation locus can be corrected using the average vector V3m, and the input operation can be recognized using the corrected vector V4.
　また縦方向の入力操作を受け付けるロック解除画面１０２Ｌが表示された状態で、統括制御部２３が行う補正量の調整についても、横方向の入力操作を受け付けるロック解除画面１０２Ｓが表示された状態で統括制御部２３が行う補正量の調整の場合と同様である。図８は、本実施形態にかかる情報処理装置が縦方向のロック解除画面を表示した状態で実行する補正量の調整について説明するための説明図である。統括制御部２３は、操作ベクトルＶ２と基準ベクトルＶ１との差を求めることで、差異ベクトルＶ３を求める。これにより、Ｖ３＝Ｖ２－Ｖ１となる。 Further, the adjustment of the correction amount performed by the overall control unit 23 in a state where the unlocking screen 102L for accepting the input operation in the vertical direction is displayed is also performed in the state in which the unlocking screen 102S for accepting the input operation in the horizontal direction is displayed. This is the same as the correction amount adjustment performed by the control unit 23. FIG. 8 is an explanatory diagram for explaining the adjustment of the correction amount that is executed in a state where the information processing apparatus according to the present embodiment displays the lock release screen in the vertical direction. The overall control unit 23 obtains a difference vector V3 by obtaining a difference between the operation vector V2 and the reference vector V1. As a result, V3 = V2−V1.
　また統括制御部２３は、待ち受け画面が表示された状態で補正量の調整を行ってもよい。図９は、本実施形態にかかる情報処理装置が表示する待ち受け画面の一例を示す説明図である。図１０は、本実施形態にかかる情報処理装置が表示する待ち受け画面の他の一例を示す説明図である。 Further, the overall control unit 23 may adjust the correction amount while the standby screen is displayed. FIG. 9 is an explanatory diagram illustrating an example of a standby screen displayed by the information processing apparatus according to the present embodiment. FIG. 10 is an explanatory diagram illustrating another example of a standby screen displayed by the information processing apparatus according to the present embodiment.
　表示制御部２１は、複数の待ち受け画面１０４のうちのいずれかを表示画面として表示する。例えば表示制御部２１は、図９に示す待ち受け画面１０４－１および図１０に示す待ち受け画面１０４－２のいずれかを表示画面として表示することができる。 The display control unit 21 displays one of the plurality of standby screens 104 as a display screen. For example, the display control unit 21 can display either the standby screen 104-1 shown in FIG. 9 or the standby screen 104-2 shown in FIG. 10 as a display screen.
　待ち受け画面１０４は、インジケータ表示領域２１１と、デスクトップ領域２１２と、ドック領域２１３とを有する。インジケータ表示領域２１１には、デスクトップ領域２１２に表示される表示画面全体のうち現在表示されている表示領域の位置を示すインジケータが表示される。図９の場合には、４つの表示領域のうち一番右側の表示領域が現在表示されていることが示されている。また図１０の場合には、４つの表示領域のうち右から２番目の表示領域が現在表示されていることが示されている。デスクトップ領域には、アプリケーションを起動するためのアイコンや、特定の機能をデスクトップに加えるウィジェットが表示される。表示制御部２１は、統括制御部２３が左右のドラッグ操作またはフリック操作を認識すると、このデスクトップ領域２１２に表示される表示領域を切り替える。ドック領域２１３は、デスクトップ領域２１２から独立した領域である。このため、デスクトップ領域２１２が左右に移動されても、ドック領域２１３は動かない。 The standby screen 104 has an indicator display area 211, a desktop area 212, and a dock area 213. In the indicator display area 211, an indicator indicating the position of the currently displayed display area in the entire display screen displayed in the desktop area 212 is displayed. In the case of FIG. 9, the rightmost display area of the four display areas is currently displayed. In the case of FIG. 10, the second display area from the right of the four display areas is currently displayed. In the desktop area, an icon for starting an application and a widget for adding a specific function to the desktop are displayed. When the overall control unit 23 recognizes the left or right drag operation or flick operation, the display control unit 21 switches the display region displayed in the desktop region 212. The dock area 213 is an area independent of the desktop area 212. For this reason, even if the desktop area 212 is moved left and right, the dock area 213 does not move.
　統括制御部２３は、ロック解除画面１０２が表示された状態では、ロック解除操作であるドラッグ操作またはフリック操作の操作軌跡に基づいて、補正量の調整を行ったが、待ち受け画面１０４が表示された状態では、表示領域切替操作であるドラッグ操作またはフリック操作に基づいて、補正量の調整を行う。図１１は、本実施形態にかかる情報処理装置が待ち受け画面を表示した状態で実行する補正量の調整について説明するための説明図である。統括制御部２３は、操作ベクトルＶ２と基準ベクトルＶ１との差を求めることで、差異ベクトルＶ３を求める。ロック解除画面１０２を表示した状態で統括制御部２３が行う補正量の調整と同様に、統括制御部２３は、求めた差異ベクトルＶ３とメモリ１３に記憶された差異ベクトルＶ３とに基づいて、補正量を調整する。 In the state where the unlock screen 102 is displayed, the overall control unit 23 adjusts the correction amount based on the operation locus of the drag operation or flick operation that is the unlock operation, but the standby screen 104 is displayed. In the state, the correction amount is adjusted based on a drag operation or a flick operation that is a display area switching operation. FIG. 11 is an explanatory diagram for explaining the adjustment of the correction amount that is executed by the information processing apparatus according to the present embodiment while the standby screen is displayed. The overall control unit 23 obtains a difference vector V3 by obtaining a difference between the operation vector V2 and the reference vector V1. Similar to the adjustment of the correction amount performed by the overall control unit 23 with the unlock screen 102 displayed, the overall control unit 23 performs correction based on the obtained difference vector V3 and the difference vector V3 stored in the memory 13. Adjust the amount.
　また統括制御部２３は、アプリケーションランチャ画面が表示された状態で、補正量の調整を行ってもよい。図１２は、本実施形態にかかる情報処理装置が表示するアプリケーションランチャ画面の一例を示す説明図である。アプリケーションランチャ画面１０６は、アイコン表示領域２２１と、スライドバー２２２と、ドック領域２２３とを有する。アイコン表示領域２２１には、複数のアイコンが並んで表示される。ここでアイコン表示領域２２１内に全てのアイコンを表示できない場合には、表示制御部２１は、一部のアイコンをアイコン表示領域２２１内に表示し、統括制御部２３がドラッグ操作またはフリック操作を認識すると、ドラッグ操作またはフリック操作に応じて、アイコン表示領域２２１内に表示させるアイコンを変更する。 Further, the overall control unit 23 may adjust the correction amount while the application launcher screen is displayed. FIG. 12 is an explanatory diagram illustrating an example of an application launcher screen displayed by the information processing apparatus according to the present embodiment. The application launcher screen 106 has an icon display area 221, a slide bar 222, and a dock area 223. In the icon display area 221, a plurality of icons are displayed side by side. If not all icons can be displayed in the icon display area 221, the display control unit 21 displays some icons in the icon display area 221, and the overall control unit 23 recognizes the drag operation or flick operation. Then, the icon displayed in the icon display area 221 is changed according to the drag operation or the flick operation.
　図１３は、本実施形態にかかる情報処理装置がアプリケーションランチャ画面を表示した状態で実行する補正量の調整について説明するための説明図である。統括制御部２３は、操作ベクトルＶ２と基準ベクトルＶ１との差を求めることで、差異ベクトルＶ３を求める。ロック解除画面１０２を表示した状態で統括制御部２３が行う補正量の調整と同様に、統括制御部２３は、求めた差異ベクトルＶ３とメモリ１３に記憶された差異ベクトルＶ３とに基づいて、補正量を調整する。 FIG. 13 is an explanatory diagram for explaining the adjustment of the correction amount executed by the information processing apparatus according to the present embodiment in a state where the application launcher screen is displayed. The overall control unit 23 obtains a difference vector V3 by obtaining a difference between the operation vector V2 and the reference vector V1. Similar to the adjustment of the correction amount performed by the overall control unit 23 with the unlock screen 102 displayed, the overall control unit 23 performs correction based on the obtained difference vector V3 and the difference vector V3 stored in the memory 13. Adjust the amount.
　なお、図９および図１０では、横方向の入力操作を受け付ける待ち受け画面１０４を示したが、待ち受け画面は縦方向の入力操作を受け付けてもよい。例えば図１２に示すアプリケーションランチャ画面１０６と同様に縦方向にスクロール可能な表示画面を待ち受け画面とすることもできる。また図１２では、アプリケーションランチャ画面１０６は、縦方向にスクロール可能な表示画面であったが、アプリケーションランチャ画面は、横方向にスクロール可能な表示画面であってもよい。 Although FIG. 9 and FIG. 10 show the standby screen 104 that accepts an input operation in the horizontal direction, the standby screen may accept an input operation in the vertical direction. For example, a display screen that can be scrolled in the vertical direction as in the application launcher screen 106 shown in FIG. 12 may be used as the standby screen. In FIG. 12, the application launcher screen 106 is a display screen that can be scrolled in the vertical direction, but the application launcher screen may be a display screen that can be scrolled in the horizontal direction.
　以上、本実施形態にかかる情報処理装置１００の構成の一例について説明した。上記の各構成要素は、同様の機能を有する他の構成要素に置き換えることができる。本実施形態を実施する時々の技術レベルに応じて、適宜、利用する構成を変更することが可能である。また、上述のような本実施形態にかかる情報処理装置１００の各機能を実現するためのコンピュータプログラムや、このようなコンピュータプログラムが格納された、コンピュータで読取り可能な記録媒体を提供することができる。記録媒体は、例えば、磁気ディスク、光ディスク、光磁気ディスク、フラッシュメモリなどである。また、上記のコンピュータプログラムは、記録媒体を用いずに、例えばネットワークを介して配信してもよい。 Heretofore, an example of the configuration of the information processing apparatus 100 according to the present embodiment has been described. Each component described above can be replaced with another component having a similar function. The configuration to be used can be changed as appropriate according to the technical level at the time of carrying out the present embodiment. In addition, a computer program for realizing each function of the information processing apparatus 100 according to the present embodiment as described above, and a computer-readable recording medium storing such a computer program can be provided. . The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like. Further, the above computer program may be distributed via a network, for example, without using a recording medium.
　次に、本実施形態にかかる情報処理装置１００の動作について説明する。図１４は、本実施形態にかかる情報処理装置の動作例を説明するためのフローチャートである。 Next, the operation of the information processing apparatus 100 according to the present embodiment will be described. FIG. 14 is a flowchart for explaining an operation example of the information processing apparatus according to the present embodiment.
　まず表示制御部２１は、統括制御部２３の指示に従って、所定の表示画面を表示する（ステップＳ１００）。例えばここで表示制御部２１が表示する表示画面は、ロック解除画面１０２、待ち受け画面１０４、アプリケーションランチャ画面１０６など、情報処理装置１００が起動した後、アプリケーションを起動するまでの間に表示される表示画面である。 First, the display control unit 21 displays a predetermined display screen according to an instruction from the overall control unit 23 (step S100). For example, the display screen displayed by the display control unit 21 here is a display that is displayed until the application is started after the information processing apparatus 100 is started, such as the unlock screen 102, the standby screen 104, and the application launcher screen 106. It is a screen.
　そして軌跡出力部２２は、タッチ操作が行われたか否かを判断する（ステップＳ１０５）。そしてタッチ操作が行われた場合、軌跡出力部２２は、タッチセンサ１２から入力された入力信号に基づいて操作軌跡を算出する（ステップＳ１１０）。 And the locus | trajectory output part 22 judges whether touch operation was performed (step S105). When a touch operation is performed, the trajectory output unit 22 calculates an operation trajectory based on the input signal input from the touch sensor 12 (step S110).
　そして軌跡出力部２２は、算出した操作軌跡が所定の適用条件を満たすか否かを判断する（ステップＳ１１５）。操作軌跡が適用条件を満たす場合、軌跡出力部２２は、メモリ１３に記憶された補正量を用いて操作軌跡を補正する（ステップＳ１２０）。このとき軌跡出力部２２は、操作軌跡を補正した補正軌跡を認識用軌跡として出力する。一方、操作軌跡が適用条件を満たさない場合には、軌跡出力部２２は、ステップＳ１２０の処理を省略することができる。このとき軌跡出力部２２は、操作軌跡を認識用軌跡として出力する。 The trajectory output unit 22 determines whether or not the calculated operation trajectory satisfies a predetermined application condition (step S115). When the operation locus satisfies the application condition, the locus output unit 22 corrects the operation locus using the correction amount stored in the memory 13 (step S120). At this time, the locus output unit 22 outputs a corrected locus obtained by correcting the operation locus as a recognition locus. On the other hand, when the operation trajectory does not satisfy the application condition, the trajectory output unit 22 can omit the process of step S120. At this time, the trajectory output unit 22 outputs the operation trajectory as a recognition trajectory.
　そして統括制御部２３は、軌跡出力部２２が出力した認識用軌跡に基づいて、入力操作を受け付け、その認識用軌跡に基づいて、入力操作を認識する（ステップＳ１２５）。 Then, the overall control unit 23 receives an input operation based on the recognition locus output by the locus output unit 22, and recognizes the input operation based on the recognition locus (step S125).
　また統括制御部２３は、操作軌跡と、入力操作について予め定められたパターンを示す基準軌跡との差異ベクトルを算出する（ステップＳ１３０）。そして統括制御部２３は、算出した差異ベクトルをメモリ１３に記憶する（ステップＳ１３５）。 Further, the overall control unit 23 calculates a difference vector between the operation trajectory and a reference trajectory indicating a predetermined pattern for the input operation (step S130). Then, the overall control unit 23 stores the calculated difference vector in the memory 13 (step S135).
　次に統括制御部２３は、今回ステップＳ１３０の処理が行われることで算出された差異ベクトルと、前回までにステップＳ１３０の処理が行われることで算出され、メモリ１３に記憶された複数の差異ベクトルの平均ベクトルを算出する（ステップＳ１４０）。そして統括制御部２３は、平均ベクトルを補正量として記憶する（ステップＳ１４５）。ここで記憶された補正量は、以降の入力操作認識において用いられる。 Next, the overall control unit 23 calculates a difference vector calculated by performing the process of step S130 this time and a plurality of difference vectors calculated by performing the process of step S130 until the previous time and stored in the memory 13. Is calculated (step S140). Then, the overall control unit 23 stores the average vector as a correction amount (Step S145). The correction amount stored here is used in subsequent input operation recognition.
　なおここでフローチャートに記述されたステップは、記載された順序に沿って時系列的に行われる処理はもちろん、必ずしも時系列的に処理されなくとも、並列的に実行される処理をも含む。また時系列的に処理されるステップでも、場合によっては適宜順序を変更することが可能である。 Note that the steps described in the flowchart here include not only processing performed in time series in the described order but also processing executed in parallel even if not necessarily processed in time series. Even in the steps processed in time series, the order can be appropriately changed depending on circumstances.
　例えば、ステップＳ１１５およびステップＳ１２０で説明された入力操作の認識と、ステップＳ１２５からステップＳ１４０で説明された補正量の調整とは、並列的に実行されてもよいし、また補正量の調整が入力操作の認識よりも先に実行されてもよい。 For example, the recognition of the input operation described in steps S115 and S120 and the adjustment of the correction amount described in steps S125 to S140 may be performed in parallel, or the adjustment of the correction amount is input. It may be executed prior to recognition of the operation.
　以上説明したように、本実施形態によれば、所定の表示画面が表示された状態で、タッチ位置の軌跡である操作軌跡に応じた特定の処理を行うとともに、その操作軌跡に基づいて補正量の調整を行う。このため、補正量の調整を行うためだけに入力操作を行う必要がなくなり、ユーザの手間を低減することが可能になる。また調整した補正量を用いて入力操作の認識を行うことで、入力操作の認識精度を改善することが可能になる。したがって、ユーザの手間を低減させつつ、入力操作の認識精度を改善することが可能になる。 As described above, according to the present embodiment, in a state where a predetermined display screen is displayed, specific processing is performed according to the operation locus that is the locus of the touch position, and the correction amount is based on the operation locus. Make adjustments. For this reason, it is not necessary to perform an input operation only for adjusting the correction amount, and it is possible to reduce the user's trouble. Also, by recognizing the input operation using the adjusted correction amount, it is possible to improve the recognition accuracy of the input operation. Therefore, it becomes possible to improve the recognition accuracy of input operation, reducing a user's effort.
　また本実施形態では、情報処理装置を起動した後、起動するアプリケーションを選択する選択操作が認識される前に表示する表示画面が表示された状態で、操作軌跡に応じた特定の処理を行うとともに、補正量の調整を行う。これにより、アプリケーションが起動される前に補正量を調整することができ、アプリケーション起動後の入力操作の認識精度を確実に改善することが可能になる。 In the present embodiment, after the information processing apparatus is activated, a specific process corresponding to the operation trajectory is performed in a state in which the display screen to be displayed is displayed before the selection operation for selecting the application to be activated is recognized. Adjust the correction amount. As a result, the correction amount can be adjusted before the application is activated, and the recognition accuracy of the input operation after the application is activated can be reliably improved.
　また本実施形態では、情報処理装置を起動した後、起動するアプリケーションを選択する選択操作が認識される前に表示する表示画面の一例として、ロック解除画面、待ち受け画面、アプリケーションランチャ画面が挙げられた。これらの表示画面は、通常の使用方法にてユーザが多く用いる表示画面であり、これらの表示画面が表示された状態で、特定の処理を行うために、ドラッグ操作およびフリック操作など情報処理装置に対して多く用いられる入力操作が確実に行われる。このため、確実に、特定処理を行うために入力される操作軌跡の特徴を収集し、補正量を調整することが可能になる。 Moreover, in this embodiment, after starting the information processing apparatus, as an example of a display screen that is displayed before a selection operation for selecting an application to be started is recognized, an unlock screen, a standby screen, and an application launcher screen are given. . These display screens are display screens that are frequently used by the user in a normal usage method. In order to perform specific processing in a state in which these display screens are displayed, information processing devices such as a drag operation and a flick operation are used. On the other hand, an input operation that is frequently used is performed reliably. For this reason, it is possible to reliably collect the characteristics of the operation trajectory input for performing the specific processing and adjust the correction amount.
　（第２の実施形態）
　次に、本発明の第２の実施形態について説明する。なお本発明の第２の実施形態にかかる情報処理装置１００の外観および構成は、第１の実施形態と同じである。 (Second Embodiment)
Next, a second embodiment of the present invention will be described. The appearance and configuration of the information processing apparatus 100 according to the second embodiment of the present invention are the same as those in the first embodiment.
　本実施形態では、所定の表示画面を表示する際に、統括制御部２３は、予め用意された複数のパターンのいずれかを所定のパターンとして決定し、表示制御部２１は、統括制御部２３が決定した所定のパターンに応じた所定の表示画面を表示する。 In the present embodiment, when the predetermined display screen is displayed, the overall control unit 23 determines any of a plurality of patterns prepared in advance as the predetermined pattern, and the display control unit 21 A predetermined display screen corresponding to the determined predetermined pattern is displayed.
　ここで本実施形態にかかる情報処理装置１００の動作例について説明する。図１５は、本実施形態にかかる情報処理装置の動作例を説明するためのフローチャートである。 Here, an operation example of the information processing apparatus 100 according to the present embodiment will be described. FIG. 15 is a flowchart for explaining an operation example of the information processing apparatus according to the present embodiment.
　まず統括制御部２３は、予め用意された複数のパターンのいずれかを所定のパターンとして決定する（ステップＳ２００）。表示制御部２１は、統括制御部２３が決定した所定のパターンに応じた表示画面を表示する。このとき統括制御部２３は、ランダムに、または予め定められた順序に従って、所定のパターンを決定する。 First, the overall control unit 23 determines any of a plurality of patterns prepared in advance as a predetermined pattern (step S200). The display control unit 21 displays a display screen according to a predetermined pattern determined by the overall control unit 23. At this time, the overall control unit 23 determines a predetermined pattern randomly or according to a predetermined order.
　例えば統括制御部２３は、延伸方向がそれぞれ異なる複数の直線状パターンのいずれかを所定のパターンとして決定する。延伸方向は、例えば矩形領域である操作面の縦または横方向の一辺と略平行な方向である。 For example, the overall control unit 23 determines any of a plurality of linear patterns having different stretching directions as a predetermined pattern. The extending direction is, for example, a direction substantially parallel to one side in the vertical or horizontal direction of the operation surface that is a rectangular region.
　具体的には、例えば表示制御部２１がロック解除画面１０２を表示画面として表示する場合には、統括制御部２３は、所定のパターンを縦または横方向の直線状パターンのいずれかに決定し、表示制御部２１は、統括制御部２３が決定した所定のパターンに応じて、図３のロック解除画面１０２Ｓまたは図４のロック解除画面１０２Ｌのいずれかを表示装置１１に表示する。 Specifically, for example, when the display control unit 21 displays the unlock screen 102 as a display screen, the overall control unit 23 determines the predetermined pattern as either a vertical or horizontal linear pattern, The display control unit 21 displays either the unlock screen 102S of FIG. 3 or the unlock screen 102L of FIG. 4 on the display device 11 according to the predetermined pattern determined by the overall control unit 23.
　また例えば表示制御部２１が待ち受け画面１０４を表示画面として表示する場合には、統括制御部２３は、所定のパターンを縦または横方向の直線状パターンのいずれかに決定し、表示制御部２１は、統括制御部２３が決定した所定のパターンに応じて、横方向の直線状パターンの場合には、図９または図１０の待ち受け画面１０４を表示装置１１に表示し、縦方向の直線状パターンの場合には、図示しない縦方向にスクロールすることのできる待ち受け画面を表示装置１１に表示する。 For example, when the display control unit 21 displays the standby screen 104 as a display screen, the overall control unit 23 determines a predetermined pattern as either a vertical or horizontal linear pattern, and the display control unit 21 In the case of a horizontal linear pattern according to the predetermined pattern determined by the overall control unit 23, the standby screen 104 of FIG. 9 or 10 is displayed on the display device 11, and the vertical linear pattern is displayed. In this case, a standby screen that can be scrolled in the vertical direction (not shown) is displayed on the display device 11.
　なおステップＳ２０５の入力操作の認識および補正量の調整処理は、図１４のステップＳ１００からステップＳ１４５と同様であるため、ここでは説明を省略する。 Note that the input operation recognition and correction amount adjustment processing in step S205 are the same as steps S100 to S145 in FIG.

　表示制御部３１は、所定の表示画面を表示部に表示する。 The display control unit 31 displays a predetermined display screen on the display unit.
　検知部３２は、操作面に対して接触又は近接した位置であるタッチ位置を検知する。 The detection unit 32 detects a touch position that is a position in contact with or close to the operation surface.
　記憶部３３は、タッチ位置の軌跡を補正する補正量を記憶する。 The storage unit 33 stores a correction amount for correcting the locus of the touch position.
　軌跡出力部３４は、検知部の検知したタッチ位置の軌跡を算出し、補正量に基づいて軌跡を補正した補正軌跡を認識用軌跡として出力する。 The locus output unit 34 calculates the locus of the touch position detected by the detection unit, and outputs a correction locus obtained by correcting the locus based on the correction amount as a recognition locus.
　制御部３５は、表示画面が表示された状態で、認識用軌跡が予め定められた所定のパターンを描く場合に特定の処理を実行し、かつ、上記状態で、軌跡と、所定のパターンとに基づいて、補正量を調整する。 The control unit 35 performs a specific process when the recognition trajectory draws a predetermined pattern in a state where the display screen is displayed. In addition, the control unit 35 performs the trajectory and the predetermined pattern in the above state. Based on this, the correction amount is adjusted.
　次に本実施形態にかかる情報処理装置３００の動作について説明する。図１７は、本実施形態にかかる情報処理装置の動作を示すフローチャートである。 Next, the operation of the information processing apparatus 300 according to the present embodiment will be described. FIG. 17 is a flowchart illustrating the operation of the information processing apparatus according to the present embodiment.
　表示制御部３１は、所定の表示画面を表示部（図示せず。）に表示する（ステップＳ３００）。 The display control unit 31 displays a predetermined display screen on a display unit (not shown) (step S300).
　検知部３２は、タッチ位置を検知する（ステップＳ３０５）。 The detection unit 32 detects the touch position (step S305).

Also, by recognizing the input operation using the adjusted correction amount, it is possible to improve the recognition accuracy of the input operation. Therefore, it becomes possible to improve the recognition accuracy of input operation, reducing a user's effort.
