図示のように、情報提示装置は、文字属性判定部1、文字属性データベース(文字属性DB)2、可読性制御知識3、可読性制御部4、表示部7を備えている。文字属性判定部1は、画面表示する文字を入力し、文字属性データベース2から文字の種別(ひらがな、カタカナ、英数字、漢字)や画数や文字密度などを取得し、入力した文字の文字属性を判定し、可読性制御部4へ出力する処理部である。文字属性データベース2は、文字毎の文字種や画数および文字密度といった文字属性を示すデータベースであり、これについては図3を用いて後述する。可読性制御知識3は、文字属性毎のぼかし強度(ぼかす度合い)を定義するための制御知識であり、可読性制御知識3についても図5~図8を用いて後述する。可読性制御部4は、文字属性判定部1が判定した文字属性に従って、可読性制御知識3からぼかし強度を取得し、文字の可読性を制御する制御部であり、ぼかし強度決定部5とぼかし処理実行部6を備えている。ぼかし強度決定部5は、文字属性判定部1が判定した文字属性に従って、可読性制御知識3を利用して文字のぼかし強度を決定するものであり、ぼかし処理実行部6は、ぼかし強度決定部5が決定した文字のぼかし強度に従って、文字のぼかし処理を行うものである。表示部7は、表示画面を有する表示装置とその表示制御部からなり、可読性制御部4が処理したぼかし文字を画面表示するものである。
図2は、実施の形態1の動作を示すフローチャートである。
情報提示装置に文字が入力されると(ステップST100)、文字属性判定部1は、入力した文字に合わせて文字属性データベース2を参照して文字属性を判定し、文字属性判定結果を出力する(ステップST110)。文字属性データベース2には、例えば図3に示すように、文字毎の文字属性として、文字種と画数と文字密度の値が格納されている。文字種は、例えば、ひらがなやカタカナ、英数字や漢字、アルファベットの大文字や小文字といった文字の種類を示す属性であり、画数とは、それぞれの文字の画数である。さらに、文字密度とは、文字を囲む領域中に占める実際の文字部分の割合といった値であり、一般的には画数の多いほどその値も大きくなる。なお、これらの文字属性の値は予め作成しておくものとする。図4は文字属性判定結果の一例であり、ここでは文字列として「横浜こどもセンターKIDS3」の場合を示している。
図9中、(a)はぼかし無し(通常表示)の状態を示すもので、文字の一例として「ビジネスホテル」(文字列1)と「温泉旅館」(文字列2)の2行が表示されるものとする。文字列1はカタカナであり、画数及び文字密度が小さい文字列であり、文字列2は漢字であり、画数及び文字密度が大きい文字列である。(b)は全ての文字に対して均等にぼかし処理(ぼかし強度:弱)を行った例であり、従来技術における文字を単純にぼかした場合に相当し、ぼけ方にばらつきが出ることになる。これに対し、(c)は実施の形態1における表示状態を示し、「ビジネスホテル」(文字列1)については、強くぼかし(ぼかし強度:強)、「温泉旅館」(文字列2)に対しては弱くぼかす(ぼかし強度:弱)制御となっている。その結果、ぼけ方に統一性があり、ぼかした文字としての統一感を与えることができる。
実施の形態2は、実施の形態1のぼかし処理に加えて、さらにぼかし強度に応じたぼかし制御を行う例である。
図10は、実施の形態2の情報提示装置の構成図である。
実施の形態2の情報提示装置は、文字属性判定部1、文字属性データベース(文字属性DB)2、可読性制御知識3、可読性制御部4a、表示部7、ぼかし処理制御部8、ぼかし処理制御知識9を備えている。ここで、可読性制御部4aにおけるぼかし処理制御部8と、ぼかし処理制御知識9の構成以外は図1に示した実施の形態1と同様であるため、対応する部分に同一符号を付してその説明を省略する。
図11のフローチャートにおいて、ステップST100~ステップST120、ステップST140の動作は図2のフローチャートに示した実施の形態1と同様である。実施の形態2では、ステップST120においてぼかし強度決定部5がぼかし強度を決定した後、ぼかし処理制御部8がぼかし処理制御知識9を利用してぼかし制御処理を行う(ステップST200)。その後、ぼかし処理実行部6はぼかし処理制御部8から出力されたぼかし制御結果に基づくぼかし処理を実行する(ステップST210)。ぼかし処理制御知識9としては、例えば図12のぼかし処理制御知識9aに示すように、ぼかし強度に合わせて文字を太字化する(ぼかし強度が大きいほど太い字とする)制御、図13のぼかし処理制御知識9bに示すように、ぼかし強度に合わせてぼかした文字を重ねる回数を変化させる(ぼかし強度が強いほど重ねる回数を多くする)制御、図14のぼかし処理制御知識9cに示すように、ぼかし強度に合わせてぼかした文字をずらしながら重ねる回数を変化させる(ぼかし強度が強いほど重ねる回数を多くする)制御、といったものがある。
・ぼかし強度(強):文字をより太くしてからぼかす
・ぼかし強度(中):文字を少し太くしてからぼかす
・ぼかし強度(弱):文字を太くしないままぼかす
といった制御知識を示している。すなわち、画数の少ない文字、密度の低い文字は、ぼかすと線が細く薄くなってしまう。そこで、文字を太くしてからぼかすことで、強めのぼかしを表現することができる。一方、画数の多い文字、密度の高い文字は、文字を太くしてからぼかすと文字がつぶれてしまう。そこで、文字を太くしないでぼかすことで、弱めのぼかしを表現することができる。
これにより、ぼかし後の文字列の印象が統一される。
・ぼかし強度(強):ぼかした文字を3回重ねて表示
・ぼかし強度(中):ぼかした文字を2回重ねて表示
・ぼかし強度(弱):ぼかした文字をそのまま表示
といった制御知識を示している。すなわち、画数の少ない文字、密度の低い文字は、ぼかすと線が細く薄くなってしまう。そこで、ぼかした文字を複数回重ねることで、強めのぼかしを表現することができる。一方、画数の多い文字、密度の高い文字は、ぼかした文字を何度も重ねると文字がつぶれてしまう。そこで、ぼかした文字を重ねないことで、弱めのぼかしを表現することができる。
これにより、ぼかし後の文字列の印象が統一される。
・ぼかし強度(強):ぼかした文字を3回ずらしながら重ねて表示
・ぼかし強度(中):ぼかした文字を2回ずらしながら重ねて表示
・ぼかし強度(弱):ぼかした文字をそのまま表示
といった制御知識であり、これは、ぼかし処理制御知識9bに加えて、さらにずらしながら重ねる制御である。
これにより、ぼかし処理制御知識9bと比較して文字の太さも調整することができる。なお、ぼかし処理制御知識9cを使ったぼかし制御として、ずらす方向は横方向でも縦方向でも、さらには縦方向及び横方向の両方であってもよい。
図中、(a)に示す表示例は、ぼかし処理制御知識9aを用いた例であり、文字を太くしてから均一にぼかす制御である。なお、ぼかし無し(通常表示)は、図9(a)で示した例と同様の「ビジネスホテル」(文字列1)、「温泉旅館」(文字列2)である。
この場合、「ビジネスホテル」(文字列1)の文字列は、ぼかし強度が「強」であるため太字にしてからぼかす処理を行っている。一方、「温泉旅館」(文字列2)の文字は、ぼかし強度が「弱」であるため、そのままぼかす処理となっている。これにより、「ビジネスホテル」の文字列(文字列1)と「温泉旅館」(文字列2)の文字列のぼかし後の印象が統一され、表示品質を向上させることができる。
また、シンボル付きのテキストや、アイコン付きのテキストは、シンボルやアイコンはそのまま表示し、文字だけをぼかしても良い。例えば、図17に示すような、シンボル(ピクトグラム)付きの「駐車場」や「トイレ」といった文字列は文字列部分のみぼかし、ピクトグラム部分についてはそのまま表示する。あるいは、シンボルも含めてぼかす、といった処理を行ってもよい。
実施の形態3は情報提示装置を車載情報機器として搭載するようにした例である。
図18は、実施の形態3の情報提示装置を示す構成図である。
実施の形態3の情報提示装置は、文字属性判定部1、文字属性データベース(文字属性DB)2、可読性制御知識3、可読性制御部4b、表示部7を備えている。ここで、可読性制御部4b内の構成以外は図1に示した実施の形態1と同様であるため、可読性制御部4b以外の構成については説明を省略する。
図19のフローチャートにおいて、ステップST100~ステップST140の動作は図2のフローチャートに示した実施の形態1と同様である。実施の形態3では、ステップST100で文字入力があった場合、可読性制御部4bの車速対応ぼかし制御部10は、入力される車速に従い、車両が走行中であるか否かを判定する(ステップST300)。ここで、車両が走行中ではないと判定した場合は、ぼかし処理を行わず、そのまま文字表示を行う(ステップST310)。すなわち、車速対応ぼかし制御部10は、文字属性判定部1、ぼかし強度決定部5及びぼかし処理実行部6に対して、ぼかし処理を行わずそのまま文字表示を行うよう指示する。一方、ステップST300において、走行中であると判定した場合、車速対応ぼかし制御部10は文字属性判定部1、ぼかし強度決定部5及びぼかし処理実行部6に対してぼかし処理を行うよう指示を出し、ステップST110~ステップST140の処理を行う。
一方、操作に不慣れなユーザでは、文字がぼけていて何が表示されているかが判別できないため、操作することを諦めさせることになり、表示画面を注視することで運転操作が疎かになってしまう、といった事態を防止することができる。
このように、本実施の形態の情報提示装置では、ユーザのスキルに合わせた安全な操作方法を提供することができる。
図中、(a)は停止時の状態を示しており、レストラン名100、レストランシンボル101、詳細情報102が全て表示される。(b)は、車速Aが0<A≦T1(T1は0を超える定数)の場合であり、詳細情報102に対しては上記のぼかし処理が行われる。(c)は車速がT1を超える場合であり、レストラン名100と詳細情報102がぼかし処理され、レストランシンボル101のみが通常表示(ぼかし処理無し)される。
このように構成することにより、車両の走行状態に応じてより適した表示状態とすることができる。
