Description

情報処理装置Information processing device
　本開示は、タッチ操作により情報を入力する入力装置を備えた情報処理装置に関する。 The present disclosure relates to an information processing apparatus including an input device that inputs information by a touch operation.
　近年、種々の電子機器において入力手段としてタッチ操作により情報の入力を行うタッチパッドを備えたものが普及している（特許文献１～４等）。例えば、特許文献１は、入力手段としてキーボードに加えてタッチパッドを備えたノートブック型のパーソナルコンピュータを開示している。また、特許文献２、３にはそれぞれ、入力手段としてタッチパッドを設けた自動車のステアリング及びカメラが開示されている。 In recent years, various electronic devices equipped with a touch pad for inputting information by a touch operation have become widespread as input means (Patent Documents 1 to 4, etc.). For example, Patent Document 1 discloses a notebook personal computer provided with a touch pad in addition to a keyboard as input means. Further, Patent Documents 2 and 3 each disclose an automobile steering and camera provided with a touch pad as input means.

　タッチパッドは、ユーザの指等が触れるだけで入力を受け付けてしまうため、ユーザが意図せずにタッチパッドに触れた場合に、誤入力の問題が生じる。 Since the touchpad accepts input only by touching the user's finger or the like, a problem of erroneous input occurs when the user touches the touchpad unintentionally.
　例えば、パーソナルコンピュータにおいては通常、タッチパッドはキーボードの近傍に配置される。このため、ユーザがキーボードを用いて入力作業を行っている最中に、ユーザが意図せずにユーザの手の掌の一部がタッチパッドに触れてしまうことが多々ある。このようなユーザが意図しないタッチパッドへの接触は誤入力を生じ、結果としてユーザの意図しない動作を発生させるという問題がある。 For example, in a personal computer, the touch pad is usually arranged near the keyboard. For this reason, a part of the palm of the user's hand often touches the touchpad unintentionally while the user is performing an input operation using the keyboard. Such a touch on the touchpad that is not intended by the user causes an erroneous input, resulting in an operation that is not intended by the user.
　本開示は、タッチパッド上で生じる誤入力の可能性を低減させることができる情報処理装置を提供する。 This disclosure provides an information processing apparatus that can reduce the possibility of erroneous input occurring on a touchpad.

The input area of the touch operation unit includes a specific area and an area other than the specific area. When the external input device is not connected to the connection terminal, the control unit enables the input by the touch operation performed in the entire area of the input area, and when the external input device is connected to the connection terminal, The input by the touch operation made is invalidated.
　本開示における第２の態様において、情報処理装置は、入力領域へのタッチ操作により情報の入力を受け付けるタッチ操作部と、タッチ操作部の入力機能の有効／無効を制御する制御部と、を備える。制御部は、所定の条件が満たされたときに、タッチ操作部の入力領域において、タッチ操作による情報の入力を受け付ける領域を一部の領域に制限する。 In the second aspect of the present disclosure, the information processing apparatus includes a touch operation unit that receives an input of information by a touch operation on the input area, and a control unit that controls validity / invalidity of an input function of the touch operation unit. . When a predetermined condition is satisfied, the control unit restricts an area for accepting input of information by the touch operation to a part of the input area of the touch operation unit.

　以下、図１～４を用いて、実施の形態１を説明する。 (Embodiment 1)
The first embodiment will be described below with reference to FIGS.
［１－１．構成］
　図１は、実施の形態１における情報処理装置の外観を示す図である。情報処理装置１００は、所定のプログラムに基づいて種々の機能を実行する。本実施の形態では情報処理装置の一例としてノートパソコンを用いた例を示す。 [1-1. Constitution]
FIG. 1 is a diagram illustrating an appearance of the information processing apparatus according to the first embodiment. The information processing apparatus 100 executes various functions based on a predetermined program. In this embodiment, an example in which a notebook computer is used as an example of the information processing apparatus is shown.
　図１に示すように、情報処理装置１００は、筐体１１０、キーボード１２０、接続端子１３０、タッチパッド１４０およびタッチパッドボタン１５０を有している。以下、各構成要素について説明を行う。 As illustrated in FIG. 1, the information processing apparatus 100 includes a housing 110, a keyboard 120, a connection terminal 130, a touch pad 140, and a touch pad button 150. Hereinafter, each component will be described.
　キーボード１２０は、情報処理装置１００の使用者からのキー入力を受け付ける。キーボード１２０は筐体１１０に配置される。 The keyboard 120 accepts key input from the user of the information processing apparatus 100. The keyboard 120 is disposed on the housing 110.
　接続端子１３０は、外部機器を接続するための端子である。外部機器には、ＳＳＤ(Ｓｏｌｉｄ　Ｓｔａｔｅ　Ｄｅｖｉｃｅ)、ＨＤＤ（Ｈａｒｄ　Ｄｉｓｋ　Ｄｒｉｖｅ）及び光ディスク装置のような外部記憶装置、並びに外部入力装置が含まれる。外部入力装置は、情報処理装置１００の使用者からの様々な入力を受け付ける装置であり、例えば、マウス、キーボード、タッチパッドを含む。本実施の形態の情報処理装置１００において接続端子１３０は、ＵＳＢ（Ｕｎｉｖｅｒａｌ　Ｓｅｒｉａｌ　Ｂｕｓ（登録商標））端子を含む。接続端子１３０は、Ｂｌｕｅｔｏｏｔｈ（登録商標）、ＰＳ／２（登録商標）等の、有線／無線を問わず汎用的なインターフェースの端子を含んでも良い。 The connection terminal 130 is a terminal for connecting an external device. External devices include SSDs (Solid State Devices), HDDs (Hard Disk Drives) and external storage devices such as optical disk devices, and external input devices. The external input device is a device that receives various inputs from the user of the information processing apparatus 100, and includes, for example, a mouse, a keyboard, and a touch pad. In the information processing apparatus 100 according to the present embodiment, the connection terminal 130 includes a USB (Universal Serial Bus (registered trademark)) terminal. The connection terminal 130 may include a general-purpose interface terminal such as Bluetooth (registered trademark) or PS / 2 (registered trademark) regardless of wired / wireless.
　タッチパッド１４０は、使用者の指やタッチペンによるタッチ操作による情報の入力を受け付ける装置である。タッチパッド１４０は、指等によりタッチされた位置を検知し、検知した位置の座標を示す情報を出力する。 The touch pad 140 is a device that receives input of information by a touch operation with a user's finger or a touch pen. The touch pad 140 detects a position touched by a finger or the like, and outputs information indicating the coordinates of the detected position.
　タッチパッドボタン１５０は押下式ボタンであり、情報処理装置１００の使用者からの入力を受け付けることで様々な指令を情報処理装置１００に伝える。タッチパッドボタン１５０はタッチパッド１４０による接触操作の補助として用いられる。 The touch pad button 150 is a push button, and transmits various commands to the information processing apparatus 100 by receiving input from the user of the information processing apparatus 100. The touch pad button 150 is used as an assist for a touch operation by the touch pad 140.
　図２は、実施の形態１における情報処理装置１００におけるタッチパッド１４０及びタッチパッドボタン１５０を拡大して示した図である。タッチパッド１４０は、使用者の指やタッチペンによるタッチ操作（接触操作）を検知する検知面を有する。タッチパッド１４０は、使用者によりタッチされた検知面上の位置の物理的な座標を検知する。検知面の一部の領域は特定領域２１０として設定される。また検知面の特定領域２１０とは異なる領域を他の領域２２０とする。同図においては特定領域２１０および他の領域２２０により、検知面のほぼ全領域となる。 FIG. 2 is an enlarged view of the touch pad 140 and the touch pad button 150 in the information processing apparatus 100 according to the first embodiment. The touch pad 140 has a detection surface that detects a touch operation (contact operation) with a user's finger or a touch pen. The touch pad 140 detects physical coordinates of a position on the detection surface touched by the user. A partial area of the detection surface is set as the specific area 210. An area different from the specific area 210 on the detection surface is defined as another area 220. In the figure, the specific area 210 and the other area 220 constitute almost the entire area of the detection surface.
　通常動作の場合、タッチパッド１４０において、検知面の特定領域２１０および他の領域を含む領域が、使用者のタッチ入力を検知可能な領域（以下「有効領域」という）に設定される。これに対して、接続端子１３０に外部入力装置が接続された場合、タッチパッド１４０の有効領域は特定領域２１０に制限される。すなわち、特定領域２１０は、有効領域が制限された場合であっても、使用者のタッチ操作を検知することができる領域である。一方、他の領域２２０は、タッチパッド１４０の有効領域が制限された場合、使用者からのタッチ操作に基づく入力が無効となる領域である。本開示において他の領域２２０は、タッチパッド１４０の検知面の外縁に沿って設定されている。なお、本開示の他の領域２２０に関して、タッチパッド１４０の中心を通る一点鎖線Ａを境界として、タッチパッドの領域を上下二つの範囲に分けた場合に、キーボード１２０に近い側の範囲内において他の領域２２０が占める面積（範囲）が、キーボード１２０から遠い側の範囲内において他の領域２２０が占める面積（範囲）よりも大きくなるように、他の領域２２０が設定されている。 In the normal operation, the area including the specific area 210 on the detection surface and other areas on the touch pad 140 is set as an area (hereinafter referred to as “effective area”) where the user's touch input can be detected. On the other hand, when an external input device is connected to the connection terminal 130, the effective area of the touch pad 140 is limited to the specific area 210. That is, the specific area 210 is an area where the user's touch operation can be detected even when the effective area is limited. On the other hand, the other area 220 is an area where the input based on the touch operation from the user is invalidated when the effective area of the touch pad 140 is limited. In the present disclosure, the other region 220 is set along the outer edge of the detection surface of the touch pad 140. In addition, regarding another area 220 of the present disclosure, when the area of the touch pad is divided into two upper and lower ranges with a one-dot chain line A passing through the center of the touch pad 140 as a boundary, the other areas within the range closer to the keyboard 120 The other area 220 is set such that the area (range) occupied by the area 220 is larger than the area (range) occupied by the other area 220 in the range far from the keyboard 120.
　図３は、実施の形態１における情報処理装置の主要な内部構成を示すブロック図である。情報処理装置１００は、プロセッサ３１０と、記憶装置３２０と、外部Ｉ／Ｏコントローラ３５０と、タッチパッドコントローラ３４０とを備える。 FIG. 3 is a block diagram illustrating a main internal configuration of the information processing apparatus according to the first embodiment. The information processing apparatus 100 includes a processor 310, a storage device 320, an external I / O controller 350, and a touch pad controller 340.
　記憶装置３２０は、情報処理装置１００の処理に必要なデータを一時的または恒久的に保存する。例えば、記憶装置３２０には、ＯＳ（Ｏｐｅｒａｔｉｎｇ　Ｓｙｓｔｅｍ）３２５やプログラムなどが保存される。記憶装置３２０には、揮発性メモリ（ＤＲＡＭ、ＳＲＡＭ等）や不揮発性メモリ（フラッシュメモリ等）、ＨＤＤ（Ｈａｒｄ　Ｄｉｓｋ　Ｄｒｉｖｅ）などが用いられる。 The storage device 320 temporarily or permanently saves data necessary for processing of the information processing device 100. For example, the storage device 320 stores an OS (Operating System) 325, a program, and the like. As the storage device 320, a volatile memory (DRAM, SRAM, etc.), a nonvolatile memory (flash memory, etc.), an HDD (Hard Disk Drive), or the like is used.
　バス３３０は、情報処理装置１００の各構成要素が送受信するデータやコマンドを送信させる。制御信号やデータはバス３３０を介して情報処理装置１００の各構成要素の間で送受信される。 The bus 330 transmits data and commands transmitted and received by each component of the information processing apparatus 100. Control signals and data are transmitted and received between the components of the information processing apparatus 100 via the bus 330.
　タッチパッドコントローラ３４０は、使用者からのタッチ操作に対応して、タッチされた座標をプロセッサ３１０が処理できる形式に変換する。例えば（Ｘ，Ｙ）のような座標形式に変換される。 The touch pad controller 340 converts the touched coordinates into a format that can be processed by the processor 310 in response to a touch operation from the user. For example, it is converted into a coordinate format such as (X, Y).
　外部Ｉ／Ｏコントローラ３５０は、接続端子１３０と電気的に接続され、接続端子１３０に接続される外部機器と所定のインターフェースに準拠した通信を行う。接続端子１３０に外部入力装置が接続されている場合、外部Ｉ／Ｏコントローラ３５０は、接続端子１３０に接続された外部入力装置の接続状態に関する情報を取得する。接続状態に関する情報は、接続の有無に関する情報を含む。外部入力装置は、マウスやタッチパッドのような、座標を指示する指示装置であり、外部入力装置に対してなされた使用者の操作にしたがい座標を示す情報を生成し出力する。外部Ｉ／Ｏコントローラ３５０は、外部入出力装置から、使用者によって外部入出力装置に指示された座標を示す情報を取得する。 The external I / O controller 350 is electrically connected to the connection terminal 130 and communicates with an external device connected to the connection terminal 130 in accordance with a predetermined interface. When an external input device is connected to the connection terminal 130, the external I / O controller 350 acquires information regarding the connection state of the external input device connected to the connection terminal 130. The information regarding the connection state includes information regarding the presence / absence of connection. The external input device is an instruction device that indicates coordinates, such as a mouse or a touch pad, and generates and outputs information indicating the coordinates in accordance with a user operation performed on the external input device. The external I / O controller 350 acquires information indicating coordinates instructed to the external input / output device by the user from the external input / output device.
　プロセッサ３１０は、外部入力装置および／またはタッチパッドコントローラ３４０からの座標の情報に基づいて、ＯＳ３２５上で管理する指示座標を計算する。例えば、プロセッサ３１０は、接続端子１３０に外部入力装置としてマウスが接続された際には、当該マウスの移動に応じて得られる情報に基づいて指示座標を計算する。プロセッサ３１０は、記憶装置３２０に保存されたプログラムを実行して情報処理装置１００の各種機能を実現する。プロセッサ３１０は、ソフトウェアと協働して各種機能を実現する汎用のプロセッサで構成できるが、ハードウェアだけで各種機能を実現するよう設計された専用のプロセッサでもよい。 The processor 310 calculates designated coordinates managed on the OS 325 based on coordinate information from the external input device and / or the touchpad controller 340. For example, when a mouse is connected to the connection terminal 130 as an external input device, the processor 310 calculates designated coordinates based on information obtained according to the movement of the mouse. The processor 310 implements various functions of the information processing apparatus 100 by executing programs stored in the storage device 320. The processor 310 can be configured by a general-purpose processor that realizes various functions in cooperation with software, but may be a dedicated processor designed to realize various functions only by hardware.
［１－２．動作］
　以上のように構成された情報処理装置１００の動作を説明する。 [1-2. Operation]
The operation of the information processing apparatus 100 configured as described above will be described.
　図４は、実施の形態１における情報処理装置の行う動作を示すフローチャートである。図４に示すフローチャートにおける各処理はプロセッサ３１０によって周期的に実行される。 FIG. 4 is a flowchart showing an operation performed by the information processing apparatus according to the first embodiment. Each process in the flowchart shown in FIG. 4 is periodically executed by the processor 310.
　本処理は、押下イベントが発生しているときに実行される（Ｓ４００）。押下イベントとは、タッチパッド１４０の検知面上に使用者の指等によるタッチ（接触）が検知されたことを示すイベントである。プロセッサ３１０は、タッチパッドコントローラ３４０を介して押下イベントを認識する。押下イベントの開始を情報処理装置１００に認識させる具体的な方法の一例として、タッチパッドコントローラ３４０が座標を取得する度に、プロセッサ３１０がその座標を、バス３３０を介して取得する方法がある。また、他の方法として、プロセッサ３１０は、ＯＳ３２５が用意するプログラム（ＡＰＩ：Application Programming Interface）を利用して、タッチパッドコントローラ３４０から得るデータに基づき、タッチの検知を行うことができ、押下イベントの開始を認識できる。 This process is executed when a press event has occurred (S400). The press event is an event indicating that a touch (contact) by a user's finger or the like is detected on the detection surface of the touch pad 140. The processor 310 recognizes a press event via the touch pad controller 340. As an example of a specific method for causing the information processing apparatus 100 to recognize the start of the pressing event, there is a method in which the processor 310 acquires the coordinates via the bus 330 every time the touchpad controller 340 acquires the coordinates. Further, as another method, the processor 310 can detect a touch based on data obtained from the touchpad controller 340 using a program (API: Application Programming Interface) prepared by the OS 325, and can detect a press event. You can recognize the start.
　プロセッサ３１０は、接続端子１３０に外部入力装置が接続されているかどうかを確認する（Ｓ４１０）。なお、プロセッサ３１０は、ＯＳ３２５に用意されているプログラム（ＡＰＩ）を利用することで、接続端子１３０に外部入力装置が接続されているか否かを確認することができる。 The processor 310 confirms whether or not an external input device is connected to the connection terminal 130 (S410). Note that the processor 310 can check whether an external input device is connected to the connection terminal 130 by using a program (API) prepared in the OS 325.
　外部入力装置が接続端子１３０に接続されていない場合（Ｓ４１０でＮＯ）、プロセッサ３１０は、タッチパッド１４０の特定領域２１０および他の領域２２０に対するタッチ操作の入力（検知）を有効にする（Ｓ４６０）。すなわち、プロセッサ３１０は、タッチパッド１４０の特定領域２１０および他の領域２２０を含む領域において、検知されたタッチ操作すなわちタッチ入力（座標）を有効なものとして扱う。 When the external input device is not connected to the connection terminal 130 (NO in S410), the processor 310 enables the input (detection) of the touch operation to the specific area 210 and the other area 220 of the touch pad 140 (S460). . That is, the processor 310 treats the detected touch operation, that is, touch input (coordinates) as valid in the area including the specific area 210 and the other area 220 of the touch pad 140.
　一方、外部入力装置が接続端子１３０に接続されている場合（Ｓ４１０でＹＥＳ）、プロセッサ３１０は、タッチパッドコントローラ３４０が取得した座標（タッチ操作された位置の座標）を取得し、記憶装置３２０に記憶する（Ｓ４２０）。 On the other hand, when the external input device is connected to the connection terminal 130 (YES in S410), the processor 310 acquires the coordinates acquired by the touch pad controller 340 (coordinates of the touch-operated position) and stores them in the storage device 320. Store (S420).
　次に、プロセッサ３１０は、記憶装置３２０に記憶された座標が特定領域２１０内の座標であるかどうかを判定する（Ｓ４３０）。具体的には、プロセッサ３１０は、記憶装置３２０に記憶された座標（Ｘ，Ｙ）が特定領域２１０の占める座標群（Ｘ１・・・Ｘｎ、Ｙ１・・・Ｙｎ）に存在するかどうかを判定する。 Next, the processor 310 determines whether or not the coordinates stored in the storage device 320 are the coordinates in the specific area 210 (S430). Specifically, the processor 310 determines whether the coordinates (X, Y) stored in the storage device 320 exist in the coordinate group (X1... Xn, Y1... Yn) occupied by the specific area 210. To do.
　記憶された座標が特定領域２１０内の座標である場合、すなわち、特定領域２１０においてタッチ操作がなされた場合（Ｓ４３０でＹＥＳ）、プロセッサ３１０は、タッチパッド１４０の特定領域２１０および他の領域２２０に対する入力を有効にする（Ｓ４４０）。すなわち、プロセッサ３１０は、タッチパッド１４０の全領域において、検知されたタッチ操作すなわちタッチ入力（座標）を有効なものとして扱う。 When the stored coordinates are coordinates in the specific area 210, that is, when a touch operation is performed in the specific area 210 (YES in S430), the processor 310 performs the process for the specific area 210 and the other area 220 of the touch pad 140. The input is validated (S440). That is, the processor 310 treats the detected touch operation, that is, touch input (coordinates) as valid in the entire area of the touch pad 140.
　一方、記憶された座標が特定領域２１０内の座標でない場合、すなわち、特定領域２１０外の領域にてタッチ操作がなされた場合（Ｓ４３０でＮＯ）、プロセッサ３１０は、タッチパッド１４０の特定領域２１０に対する入力を有効にするとともに、他の領域２２０に対する入力を無効にする（Ｓ４５０）。すなわち、プロセッサ３１０は、タッチパッド１４０の特定領域２１０において検知されたタッチ入力を有効として扱うが、他の領域２２０において検知されたタッチ入力は無効として扱う。タッチ入力を無効にする方法としては、例えば、タッチパッドコントローラ３４０が取得する座標情報をフックし、ＯＳ３２５に伝えないようにすることが考えられる。ここで、フックとは、タッチパッドコントローラ３４０とＯＳ３２５の間の情報に割り込みをかけて情報の伝達を遮ることである。 On the other hand, when the stored coordinates are not coordinates in the specific area 210, that is, when a touch operation is performed in an area outside the specific area 210 (NO in S430), the processor 310 performs the operation on the specific area 210 of the touch pad 140. The input is validated and the input to the other area 220 is invalidated (S450). That is, the processor 310 treats the touch input detected in the specific area 210 of the touch pad 140 as valid, but treats the touch input detected in the other area 220 as invalid. As a method of invalidating the touch input, for example, it is conceivable that the coordinate information acquired by the touch pad controller 340 is hooked and not transmitted to the OS 325. Here, the hook is to interrupt information transmission by interrupting information between the touchpad controller 340 and the OS 325.
　以上のように本実施形態の情報処理装置１００は、マウスのような外部入力装置が接続されている場合、タッチパッド１４０の検知面における有効領域を一部の領域（特定領域２１０）に制限する。このようにタッチパッド１４０の有効領域を制限することにより、タッチパッド１４０の誤操作を低減できる。 As described above, the information processing apparatus 100 according to the present embodiment limits the effective area on the detection surface of the touch pad 140 to a partial area (specific area 210) when an external input device such as a mouse is connected. . By limiting the effective area of the touch pad 140 in this way, erroneous operations of the touch pad 140 can be reduced.
［１－３．効果等］
　以上のように、本実施の形態の情報処理装置１００は、入力領域へのタッチ操作により情報の入力を受け付けるタッチパッド１４０と、タッチパッド１４０の入力機能の有効／無効を制御するプロセッサ３１０と、外部入力装置を接続する接続端子１３０と、を備える。タッチパッド１４０の入力領域は、特定領域２１０と、特定領域２１０と異なる他の領域２２０とを含む。プロセッサ３１０は、接続端子１３０に外部入力装置が接続されていない場合、入力領域の特定領域２１０と他の領域２２０においてなされたタッチ操作による入力を有効にする。一方、接続端子１３０に外部入力装置が接続されている場合、プロセッサ３１０は、他の領域２２０でなされたタッチ操作による入力を無効にする。 [1-3. Effect]
As described above, the information processing apparatus 100 according to the present embodiment includes the touch pad 140 that receives input of information by a touch operation on the input area, the processor 310 that controls the validity / invalidity of the input function of the touch pad 140, And a connection terminal 130 for connecting an external input device. The input area of the touch pad 140 includes a specific area 210 and another area 220 different from the specific area 210. When an external input device is not connected to the connection terminal 130, the processor 310 validates an input by a touch operation made in the specific area 210 of the input area and the other area 220. On the other hand, when an external input device is connected to the connection terminal 130, the processor 310 invalidates the input by the touch operation performed in the other area 220.
　以上の構成により、外部入力装置が接続されている際は、情報処理装置１００において、タッチパッド１４０の一部に使用者の指等がタッチされても、当該タッチを入力として処理されなくなる。これにより、使用者が外部入力装置を情報処理装置１００に接続して使用する状況、言い換えれば情報処理装置１００に備えられたタッチパッド１４０を使わない可能性が高い状況において、使用者が誤ってタッチパッド１４０に触れることで生じる誤入力の可能性を低減させることができる。 With the above configuration, when an external input device is connected, even if a user's finger or the like is touched on a part of the touch pad 140 in the information processing device 100, the touch is not processed as an input. Accordingly, in a situation where the user uses the external input device connected to the information processing apparatus 100, in other words, in a situation where there is a high possibility that the user does not use the touch pad 140 provided in the information processing apparatus 100, the user mistakenly The possibility of erroneous input caused by touching the touch pad 140 can be reduced.
　また、本開示の情報処理装置１００において、プロセッサ３１０は外部入力装置が接続されている際は、検知面上における周縁の領域２２０への入力を無効にしている。 Further, in the information processing apparatus 100 of the present disclosure, the processor 310 disables input to the peripheral area 220 on the detection surface when an external input device is connected.
　このようにすると、タッチパッド１４０の検知面の中で入力が生じる際により接触し易い箇所（タッチパッド１４０の周縁）を優先して無効にすることができる。上記の制御によれば、外部入力装置を接続している際でもタッチパッド１４０の中央寄りの部分（特定領域２１０）は使用できるので、使用者の利便性を維持しつつ誤入力を防止することができる。 In this way, it is possible to prioritize and invalidate a portion (periphery of the touch pad 140) that is more likely to be touched when an input occurs in the detection surface of the touch pad 140. According to the above control, even when an external input device is connected, the portion near the center of the touch pad 140 (specific area 210) can be used, so that erroneous input is prevented while maintaining user convenience. Can do.
　また、外部入力装置の接続時にタッチ入力が無効になる他の領域２２０について、タッチパッド１４０の中心からキーボード１２０側の領域の範囲（面積）を、それ以外の領域の範囲（面積）よりも大きくなるように他の領域２２０を設定している。 In addition, for the other region 220 in which touch input is disabled when the external input device is connected, the range (area) of the region on the keyboard 120 side from the center of the touch pad 140 is larger than the range (area) of the other regions. Another area 220 is set so as to be.
　このようにすると、タッチパッド１４０の検知面のうち誤入力が生じる際により接触し易い箇所を優先して無効にすることができる。一般にタッチパッドで誤入力が発生しやすい箇所はタッチパッドの周縁であってキーボード近傍の箇所であり、タッチパッド１４０の下方向寄りの部分（特定領域２１０）は誤入力が生じ難いと考えられる。上記の制御によれば、外部入力装置を接続している際でも、タッチパッド１４０の下方向寄りの部分（特定領域２１０）は使用をすることができるので、使用者の利便性を維持しつつ誤入力を防止することができる。 In this way, it is possible to prioritize and invalidate a portion of the detection surface of the touch pad 140 that is more likely to come into contact when an erroneous input occurs. In general, the place where erroneous input is likely to occur on the touch pad is the periphery of the touch pad and in the vicinity of the keyboard, and the portion closer to the lower side of the touch pad 140 (specific area 210) is considered to be less likely to cause erroneous input. According to the control described above, even when an external input device is connected, the lower portion (specific area 210) of the touch pad 140 can be used, so that the convenience of the user is maintained. Incorrect input can be prevented.
　（実施の形態２）
　情報処理装置１００の別の動作例を説明する。本実施形態の情報処理装置１００の構成は実施の形態１で説明したとおりである。図５のフローチャートを用いて実施の形態２における情報処理装置１００の動作を説明する。図５に示すフローチャートにおける各処理はプロセッサ３１０よって周期的に実行される。 (Embodiment 2)
Another operation example of the information processing apparatus 100 will be described. The configuration of the information processing apparatus 100 according to the present embodiment is as described in the first embodiment. The operation of the information processing apparatus 100 in the second embodiment will be described using the flowchart of FIG. Each process in the flowchart shown in FIG. 5 is periodically executed by the processor 310.
　本処理は、押下イベントが発生しているときに実行される（Ｓ５００）。押下イベントが発生している場合、まず、プロセッサ３１０は、接続端子１３０に外部入力装置が接続されているかどうかを確認する（Ｓ５１０）。 This process is executed when a press event has occurred (S500). If a press event has occurred, first, the processor 310 checks whether or not an external input device is connected to the connection terminal 130 (S510).
　外部入力装置が接続されていない場合（Ｓ５１０でＮＯ）、プロセッサ３１０は、タッチパッド１４０の検知面の全領域に対する入力を有効にする（Ｓ５６０）。すなわち、プロセッサ３１０は、全領域に対するタッチ入力を有効な入力として扱う。 If the external input device is not connected (NO in S510), the processor 310 enables input to the entire area of the detection surface of the touch pad 140 (S560). That is, the processor 310 treats the touch input for the entire area as a valid input.
　一方、外部入力装置が接続されている場合（Ｓ５１０でＹＥＳ）、プロセッサ３１０は、タッチパッドコントローラ３４０からタッチ操作の開始位置の座標を取得し、記憶装置３２０に記憶する（Ｓ５２０）。ここで、タッチ操作とは、指やタッチペンが検知面にタッチされてから、指やタッチペンが検知面から離れるまでの連続した操作をいう。このような連続した操作として、例えば、スライド、スワイプ、ピンチ、ストレッチ、ドラッグのようなジェスチャ操作がある。よって、タッチ操作の開始位置とは、そのような連続したタッチ操作がなされた場合、最初にタッチされた検知面の位置をいう。プロセッサ３１０は、押下イベントの検出後、タッチが終了したこと（すなわち、指やタッチペンが検知面から離れたこと）を示すイベントが検出されるまでの間は、現在検出されているタッチ操作が連続したタッチ操作であると認識できる。 On the other hand, when the external input device is connected (YES in S510), the processor 310 acquires the coordinates of the start position of the touch operation from the touch pad controller 340 and stores them in the storage device 320 (S520). Here, the touch operation refers to a continuous operation after the finger or touch pen is touched on the detection surface until the finger or touch pen leaves the detection surface. Such continuous operations include, for example, gesture operations such as slide, swipe, pinch, stretch, and drag. Therefore, the start position of the touch operation refers to the position of the detection surface touched first when such a continuous touch operation is performed. After detecting the pressing event, the processor 310 continues the touch operation that is currently detected until an event indicating that the touch has ended (that is, the finger or the touch pen has moved away from the detection surface) is detected. Can be recognized as touch operation.
　次に、プロセッサ３１０は、記憶装置３２０に記憶された、タッチ操作の開始位置の座標が特定領域２１０内の座標であるかどうかを判定する（Ｓ５３０）。 Next, the processor 310 determines whether or not the coordinates of the start position of the touch operation stored in the storage device 320 are the coordinates in the specific area 210 (S530).
　タッチ操作の開始位置の座標が特定領域２１０内の座標である場合（Ｓ５３０でＹＥＳ）、プロセッサ３１０は、特定領域２１０および他の領域２２０に対する入力を有効にする（Ｓ５４０）。すなわち、プロセッサ３１０は、検知面の特定領域２１０および他の領域２２０を含む領域において、検出されたタッチ入力を有効な入力として扱う。 When the coordinates of the start position of the touch operation are the coordinates in the specific area 210 (YES in S530), the processor 310 validates the input to the specific area 210 and the other area 220 (S540). That is, the processor 310 treats the detected touch input as an effective input in the area including the specific area 210 and the other area 220 on the detection surface.
　このようにプロセッサ３１０は、タッチ操作の開始位置の座標が特定領域２１０内（すなわち、他の領域２２０の外）であれば、情報処理装置１００に外部入力装置が接続されている場合でも、検知面の全領域でのタッチ入力を有効にする。このように制御することにより、特定領域２１０内から特定領域２１０外へ連続したタッチ操作（誤入力では無い可能性の高い入力）を、誤入力であると判定してしまうことを低減できる。すなわち、本実施形態では、特定領域２１０から他の領域２２０に継続してタッチされて入力される可能性を考慮し、一連のタッチ操作の開始位置が特定領域２１０内で検知されたならば、その後、他の領域２２０において検出されたタッチ入力を無効にしないようにしている。これにより、使用者は特定領域２１０から指を離さない限りは、他の領域２２０へ継続して、スライドやスワイプ等の連続したタッチ操作を行うことができる。 As described above, the processor 310 detects the coordinates of the start position of the touch operation within the specific area 210 (that is, outside the other area 220) even when an external input device is connected to the information processing apparatus 100. Enable touch input on all areas of the surface. By controlling in this way, it is possible to reduce the determination that a continuous touch operation (input that is not likely to be an erroneous input) from the specific area 210 to the outside of the specific area 210 is an erroneous input. That is, in the present embodiment, in consideration of the possibility of being continuously touched and input from the specific area 210 to another area 220, if the start position of a series of touch operations is detected in the specific area 210, Thereafter, the touch input detected in the other area 220 is not invalidated. Thus, as long as the user does not release the finger from the specific area 210, the user can continue to another area 220 and perform a continuous touch operation such as a slide or swipe.
　一方、タッチ操作の開始位置の座標が特定領域２１０の外の座標である場合（Ｓ５３０でＮＯ）、プロセッサ３１０は、特定領域２１０に対するタッチ入力を有効にするが、他の領域２２０に対するタッチ入力を無効にする（Ｓ５５０）。すなわち、プロセッサ３１０は、特定領域２１０に対するタッチ入力は有効な入力として扱い、他の領域２２０に対するタッチ入力は無効な入力として扱う。 On the other hand, when the coordinates of the start position of the touch operation are coordinates outside the specific area 210 (NO in S530), the processor 310 validates the touch input for the specific area 210, but does not perform the touch input for the other area 220. Invalidate (S550). That is, the processor 310 treats the touch input for the specific area 210 as a valid input and treats the touch input for the other area 220 as an invalid input.
　以上のように、本実施形態では、連続したタッチ操作の開始位置の座標に基づき、特定領域２１０以外の領域２２０に対するタッチ入力の有効／無効を決定している。これにより、特定領域２１０から開始されたジェスチャ操作を、その操作が終了するまでは、有効なタッチ操作として認識できる。例えば、図６に示すように、特定領域２１０の一点Ａから他の領域２２０の一点Ｂまで連続してタッチ操作が行われた場合、タッチ操作の開始点が特定領域２１０内であれば（Ｓ５３０でＹＥＳ）、移動中に他の領域２２０でタッチ操作が検出されても、その操作は有効なタッチ入力として扱われる（Ｓ５４０）。 As described above, in this embodiment, the validity / invalidity of the touch input to the area 220 other than the specific area 210 is determined based on the coordinates of the start position of the continuous touch operation. Thereby, the gesture operation started from the specific area 210 can be recognized as an effective touch operation until the operation is completed. For example, as shown in FIG. 6, when a touch operation is continuously performed from one point A of the specific area 210 to one point B of the other area 220, the start point of the touch operation is within the specific area 210 (S530). Even if a touch operation is detected in another area 220 during movement, the operation is treated as a valid touch input (S540).
　逆に、特定領域２１０の外の領域２２０から特定領域２１０まで連続してタッチ操作が行われた場合、タッチ操作の開始点が特定領域２１０内でないことから（Ｓ５３０でＮＯ）、タッチ操作が他の領域２２０でなされている間は、タッチ入力は無効な入力として処理される（Ｓ５５０）。その後、タッチ操作が特定領域２１０で検出されると、そのタッチ操作は有効な入力として処理される（Ｓ５５０）。 On the other hand, when a touch operation is continuously performed from the area 220 outside the specific area 210 to the specific area 210, the touch operation start point is not within the specific area 210 (NO in S530). In the area 220, the touch input is processed as an invalid input (S550). Thereafter, when a touch operation is detected in the specific area 210, the touch operation is processed as a valid input (S550).
　以上のように、実施の形態１、２に開示した情報処理装置１００は、入力領域へのタッチ操作により情報の入力を受け付けるタッチパッド１４０と、タッチパッド１４０の入力機能の有効／無効を制御するプロセッサ３１０と、を備える。プロセッサ３１０は、所定の条件が満たされたときに、タッチ操作部の入力領域において、タッチ操作による情報の入力を受け付ける領域を一部の領域に制限する。例えば、情報処理装置１００に外部入力装置が接続されている場合、タッチ操作による情報の入力を受け付ける領域を一部の領域に制限する。このようにタッチ操作部の入力領域を制限することにより、情報処理装置１００が外部入力装置に接続されている状況のような、タッチパッド１４０が使われる可能性が低い状況において、使用者が誤ってタッチパッド１４０に触れることで生じる誤入力の可能性を低減させることができる。 As described above, the information processing apparatus 100 disclosed in the first and second embodiments controls the touch pad 140 that receives input of information by a touch operation on the input area, and the validity / invalidity of the input function of the touch pad 140. Processor 310. When a predetermined condition is satisfied, the processor 310 limits an area for accepting input of information by the touch operation to a part of the input area of the touch operation unit. For example, when an external input device is connected to the information processing apparatus 100, an area for receiving input of information by a touch operation is limited to a part of the area. By restricting the input area of the touch operation unit in this way, the user is mistaken in a situation where the touch pad 140 is unlikely to be used, such as a situation where the information processing apparatus 100 is connected to an external input device. Thus, the possibility of erroneous input caused by touching the touch pad 140 can be reduced.
　（他の実施の形態）
　図４または図５のフローチャートに示す機能は、タッチパッド１４０を制御するタッチパッドドライバにより実現されてもよい。または、タッチパッドドライバとは別のユーティリティプログラムにより実現されてもよい。その場合、ユーティリティプログラムは、タッチパッドドライバとＯＳ３２５の間に介在し、タッチパッドドライバで検出されたタッチ入力座標に対して、有効／無効を判断し、有効なタッチ入力座標のみをＯＳ３２５に伝えるようにすればよい。 (Other embodiments)
The functions shown in the flowchart of FIG. 4 or 5 may be realized by a touch pad driver that controls the touch pad 140. Alternatively, it may be realized by a utility program different from the touchpad driver. In that case, the utility program is interposed between the touch pad driver and the OS 325, determines whether the touch input coordinates detected by the touch pad driver are valid or invalid, and transmits only the valid touch input coordinates to the OS 325. You can do it.
　上記の実施形態では、タッチパッド１４０の検知面における有効領域を制限するか否かの所定の条件として、情報処理装置１００に対して外部入力装置が接続されているか否かを判断した（Ｓ４１０、Ｓ５１０）。タッチパッド１４０の検知面における有効領域を制限するか否かを判断する際の基準となる条件は、これに限定されず、例えば、所定の操作がなされたことを条件としてもよい。所定の操作には、例えば、所定のキーが押下されたことや、タッチパッド１４０の検知面の所定領域がタッチされたことが含まれる。上記の実施形態では、特定領域２１０および他の領域２２０により、検知面のほぼ全領域となる形態を示している。これには限定されず、検知面には特定領域２１０および他の領域２２０以外の第３の領域を含んでいても良い。 In the above embodiment, it is determined whether or not an external input device is connected to the information processing apparatus 100 as a predetermined condition as to whether or not to limit the effective area on the detection surface of the touch pad 140 (S410, S510). The condition used as a reference when determining whether or not to limit the effective area on the detection surface of the touch pad 140 is not limited to this, and may be a condition that a predetermined operation is performed, for example. The predetermined operation includes, for example, pressing a predetermined key or touching a predetermined area on the detection surface of the touch pad 140. In the above-described embodiment, the specific area 210 and the other area 220 form a substantially entire area of the detection surface. However, the detection surface may include a third area other than the specific area 210 and the other area 220.
