Description

図1は、本発明の一実施形態に係る携帯型装置1の要部構成を示すブロック図である。携帯型装置1は筐体を把持した片手で操作可能なサイズおよび形状の装置であり、図示のように、タッチパネル11、制御部12、記憶部13、および傾きセンサ(傾き検出部)100を備えている。タッチパネル11は、制御部12の制御に従って画像を表示する表示部111と、ユーザの入力操作を受け付ける入力部112とを備えている。表示部111の表示面が入力部112の入力面を兼ねており、表示面に対するユーザのタッチ操作を携帯型装置1に対する入力操作として受け付ける。制御部12は、携帯型装置1が備える各部を統括的に制御するものであり、操作判定部121、メニュー表示部(表示手段)122、操作記録部123、操作解析部124、持ち手判定部(持ち手判定手段)125、無効領域設定部(無効領域設定手段、解除手段)126、および無操作時間計測部129を備えている。記憶部13は、携帯型装置1が使用する各種データを格納する。図示の例では、ユーザの操作の軌跡を示す操作データ131と、携帯型装置1の持ち手を判定するための持ち手判定条件133とが格納されている。また、傾きセンサ100は、携帯型装置1が保持されている姿勢を特定するためのものである。なお、傾きセンサ100は、ジャイロセンサや加速度センサなどであってもよい。
ッグ操作に限られない。メニュー表示部122は、メニュー表示操作が行われた旨の通知を操作判定部121から受信したときに、表示部111にメニューを表示させる。具体的には、図2に示すような画面を表示する。同図の例では、メニューのオブジェクトO(以下、メニューと呼ぶ)が表示されている。このメニューは、表示面の端部を始点として表示面の中央側に向かって延在しており、複数の項目(この例では6つ)を含む。ユーザは、所望の項目を選択することにより、その項目に対応する処理を携帯型装置1に実行させることができる。操作記録部123は、入力部112が受け付けた入力操作の内容を示す操作データ131を記録し、操作解析部124は、操作データ131を解析し、持ち手判定部125は、操作解析部124の解析結果から持ち手判定条件133に従って持ち手を判別する。無効領域設定部126は、持ち手判定部125の判別結果に応じた位置に無効領域を設定し、設定した無効領域を操作判定部121に通知すると共に、該無効領域に対する操作を受け付けないように指示することによって、無効領域内で行われた操作を無効にする。なお、操作の無効化方法はこれに限定されず、例えば入力部112を制御して無効領域内で行われた操作が操作判定部121に通知されないようにしてもよい。また、無効領域内に操作の対象となるオブジェクトを表示しないように制御してもよい。
図2の画面例では、表示面右下隅の座標を基準座標A(X0,Y0)とし、メニュー右下隅の座標をメニュー基準点B(X0,Y1)としている。また、メニューの幅をW、高さをH、基準座標Aからメニュー基準点Bまでの距離をD(D=Y0-Y1)で示している。オブジェクトOの画像データと共に、上記各パラメータ(W,H,D)を予め記憶しておくことにより、図2のような表示を行うことができる。なお、メニュー表示操作を行った指(典型的には親指)にて、スムーズに項目を選択することができるように、メニュー基準点Bのy座標Y1は、メニュー表示操作の始点のy座標と同一か、またはこれに近い値に設定することが好ましい。なお、表示面の左端を始点とするドラッグ操作を行った場合、表示面の左端を始点としてメニューを表示する。
(N×X0-W)/N<X<X0,((N-1)×Y0+Y1)/N<Y<Y0
と表される。
広く設定しないことが好ましい。これにより、矩形形状の表示面の辺に沿って帯状の無効化領域を設定している特許文献1(同文献の図3、図7等)の技術と比べて、無効領域を設定した状態においても、広い範囲でユーザの入力操作を受け付けることができる。
持ち手判定方法について、メニュー表示操作の軌跡を示す図6に基づいて説明する。上述のように、メニュー表示操作は、表示面の右端または左端を始点とするドラッグ操作である。このため、右手でメニュー表示操作を行ったときの軌跡は、同図の(a)に示すように、表示面の左端から右上に向かう円弧状の軌跡L11、または表示面の右端から左下に向かう円弧状の軌跡L12となる。一方、左手でメニュー表示操作を行ったときの軌跡は、同図(b)に示すように、表示面の左端から右下に向かう円弧状の軌跡L14、または表示面の右端から左上に向かう円弧状の軌跡L13となる。以下では、左端から右上に向かう円弧状の軌跡を右上がりの軌跡と呼び、右端から左下に向かう円弧状の軌跡を左下がりの軌跡と呼ぶ。同様に、左端から右下に向かう円弧状の軌跡を右下がりの軌跡と呼び、右端から左上に向かう円弧状の軌跡を左上がりの軌跡と呼ぶ。
図7の無効領域設定処理では、入力部112がメニュー表示指示を受け付け(S101)、操作判定部121がメニューを表示させる操作を受け付けた旨をメニュー表示部122に通知する。また、操作判定部121は、メニューを表示させる操作の軌跡を示すデータを操作記録部123に送る。そして、メニュー表示部122は、メニューを表示部111に表示する(S102;表示ステップ)。また、操作記録部123は、操作の軌跡を示す上記データを操作データ131として記録し(S103)、その旨を操作解析部124に通知する。
け付けた入力操作に着目すれば、端部を始点とするドラッグ操作(メニューを表示させる操作)が行われたときに、持ち手の判定結果に応じた無効領域を設定する処理であると表現できる。このように、携帯型装置1は、メニューを表示するタイミング(端部を始点とするドラッグ操作が行われたタイミング)にて、無効領域を設定する。つまり、携帯型装置1は、親指の根元付近が表示面に触れてしまうことによる誤操作が生じる可能性があり、無効領域を設定する必要性が高い状態となったとき(メニューが表示されているとき)に無効領域を設定する。言い換えれば、上記のような誤操作が生じる可能性の低いときには無効領域を設定しない。これにより、常に無効領域を設定する上記特許文献1の技術と比べて、表示画面の全面にて入力操作を受け付け可能な期間を長くすることができる。なお、表示するオブジェクトは、入力操作の対象となるものであればよく、メニューに限られない。また、上記オブジェクトを表示させるための操作は、画面端を始点とするものであればよく、例えば画面の上または下端を始点とするものであってもよい。
本実施形態では、図1に示す構成の携帯型装置1が、上記実施形態とは異なる方式で持ち手判定を行って無効領域を設定する例を図8に基づいて説明する。図8の左側のフローチャートでは、図7の例と同様に、まず、メニューの表示操作を受け付け(S101)、メニューを表示する(S102)。メニューが表示されている状態において、入力部112が表示面に対するタッチ操作を受け付ける(S203)と、操作判定部121は、表示面上において指が触れた領域であるタッチ領域を示すデータを操作記録部123に送る(S203)。そして、操作記録部123は、タッチ領域を示す上記データを操作データ131として記憶部13に記録し(S204)、その旨を操作解析部124に通知する。
析部124は、持ち手判定の対象となるタッチ領域の重心の位置を示す情報(例えば座標)と共に、その旨を持ち手判定部125に通知する。
(N×X0-W)/N<X<X0,((N-1)×Y0+Y1)/N<Y<Y0
と設定してもよい(図4参照)。左手側の期待押下領域も同様である。無論、期待押下領域は、メニューへの入力操作時に指が触れる可能性が高い領域を含むものであればよく、この例に限られない。例えば、図5の無効領域のように、携帯型装置1の持ち手側の角(右下角または左下角)からメニューに向かうにつれて幅広となる領域を期待押下領域としてもよい。期待押下領域の形状も無効領域の形状と同様、矩形および五角形に限られず、台形、円形、三角形、および、六角形以上の多角形などであってもよい。また、期待押下領域と無効領域とは、同一の領域であってもよいし、異なる領域であってもよい。
本実施形態では、図1に示す構成の携帯型装置1が、上記実施形態とは異なる方式で持ち手判定を行って無効領域を設定する例を図9および図10に基づいて説明する。図9の(a)に示すように、携帯型装置1を右手持ちしているときには、親指の付け根に近い携帯型装置1の角(図9の(a)において丸で囲んだ角)が他の角よりも鉛直下方向に位置するように、携帯型装置1が右下がりに傾く。一方、左手持ちしているときには、図9の(b)に示すように左下がりに傾く。これは、片手でしっかりと携帯型装置1を保持しながら操作するためには、脇を締めて、肘を体側面に密着させ固定する必要があり、さらに、掌と携帯型装置1を密着させた状態で、携帯型装置1の左右端を、掌の親指の根本部分(親指内転筋)と、小指・薬指・中指・人指し指の第1間接とで、携帯型装置1の片方の端を掌下部に沿わせる形で挟み込むように保持しながら親指で操作するため、携帯型装置1の左右端のどちらか一方を下方向へ向けることになることによる。
持ち手判定方法のさらに他の例を図11および図12に基づいて説明する。図11は、上下方向のドラッグ操作の軌跡を示す図であり、図12は、ドラッグ操作の軌跡の解析によって持ち手を判定する場合の無効領域設定処理の一例を示すフローチャートである。図11の(a)に示すように、上下方向のドラッグ操作を右手の親指で行う場合、その付け根を支点として親指が動かされる結果、表示面に描かれる軌跡は左側に突出した円弧状となる。一方、上下方向のドラッグ操作を左手の親指で行う場合、表示面に描かれる軌跡は右側に突出した円弧状となる。よって、ドラッグ操作の軌跡が何れの方向に突出しているかを特定することによって、持ち手を判定することができる。つまり、持ち手判定条件133を、ドラッグ操作の軌跡が左側に突き出た弧であれば右手持ちであり、右側に突き出た弧であれば左手持ちであることを示すものとして、持ち手の判定を行うことができる。
無効領域の解除について、図13に基づいて説明する。なお、図13のフローチャートは、無効領域が設定された後の処理を示している。無効領域を設定した無効領域設定部126は、無操作時間計測部129に無操作時間を計測するように指示し、無操作時間計測部129は、この指示に従って無操作時間の計測を開始する(S501)。なお、無操作時間とは、入力部112に対する入力操作が行われていない状態の継続時間である。
ドラッグ操作の軌跡に基づいて持ち手を判定する方法は、上記各実施形態の例に限られない。例えば、右手でドラッグ操作を行ったときの軌跡と、左手でドラッグ操作を行ったときの軌跡とを、判定用の軌跡として事前に登録しておき、登録された軌跡と、検出されたドラッグ操作の軌跡とのパターンマッチングによって持ち手を判定してもよい。さらに、上記各実施形態で示した持ち手の判定方法を併用し、予め定めた優先度の高い判定方法から順に適用し、最初に出た持ち手の判定結果を採用すればよい。これにより、例えば、傾きからは持ち手が判定できなかった場合に、ドラッグ操作の軌跡から持ち手を判定して無効領域を設定することも可能になる。
携帯型装置1の制御ブロック(特に制御部12)は、集積回路(ICチップ)等に形成
された論理回路(ハードウェア)によって実現してもよいし、CPU(Central Processing Unit)を用いてソフトウェアによって実現してもよい。後者の場合、携帯型装置1は
、各機能を実現するソフトウェアである制御プログラムの命令を実行するCPU、上記制御プログラムおよび各種データがコンピュータ(またはCPU)で読み取り可能に記録されたROM(Read Only Memory)または記憶装置(これらを「記録媒体」と称する)、上記制御プログラムを展開するRAM(Random Access Memory)などを備えている。そして、コンピュータ(またはCPU)が上記制御プログラムを上記記録媒体から読み取って実行することにより、本発明の目的が達成される。上記記録媒体としては、「一時的でない有形の媒体」、例えば、テープ、ディスク、カード、半導体メモリ、プログラマブルな論理回路などを用いることができる。また、上記制御プログラムは、該制御プログラムを伝送可能な任意の伝送媒体(通信ネットワークや放送波等)を介して上記コンピュータに供給されてもよい。なお、本発明は、上記制御プログラムが電子的な伝送によって具現化された、搬送波に埋め込まれたデータ信号の形態でも実現され得る。
本発明の態様1に係る携帯型装置1は、画像を表示する表示面に対する入力操作を受け付ける携帯型装置であって、所定の入力操作に応じて、上記表示面の一部の領域に、入力操作の対象となる入力対象オブジェクト(メニュー)を表示する表示手段(メニュー表示部122)と、上記携帯型装置が右手で把持されているか、左手で把持されているかを判定する持ち手判定手段(持ち手判定部125)と、上記入力対象オブジェクトの表示中に、該入力対象オブジェクトが表示されていない領域であって、上記持ち手判定手段の判定結果に応じた領域に対する入力操作を無効とする無効領域設定手段(無効領域設定部126)と、を備えている。上記の構成によれば、入力対象オブジェクト(以下、必要に応じてオブジェクトと略称する)の表示中に、持ち手の判定結果に応じた領域を、該領域に対する入力操作を無効にする無効領域に設定するので、オブジェクトに対する入力操作を行うときにオブジェクト以外の領域に誤って触れてしまうことによる誤操作を防ぐことができる。また、オブジェクトの表示中に無効領域を設定するため、オブジェクトが表示されるまでの期間、表示面の全面での入力操作の受け付けが可能である。
手段は、接触が検出された期待接触領域を含む領域に対する入力操作を無効にしてもよい。上記構成によれば、持ち手判定のための特別な構成が不要であり、また持ち手判定のための操作を行わせる必要もなく、期待接触領域を含む領域を無効領域とするので、オブジェクトに対する入力操作時の誤操作を適切に防ぐことができる。
帯型装置をコンピュータにて実現させる携帯型装置の制御プログラム、およびそれを記録したコンピュータ読み取り可能な記録媒体も、本発明の範疇に入る。本発明は上述した各実施形態に限定されるものではなく、請求項に示した範囲で種々の変更が可能であり、異なる実施形態にそれぞれ開示された技術的手段を適宜組み合わせて得られる実施形態についても本発明の技術的範囲に含まれる。さらに、各実施形態にそれぞれ開示された技術的手段を組み合わせることにより、新しい技術的特徴を形成することができる。
