Abstract
Description
図1は本発明の実施の形態1におけるタッチパネルを備えた表示装置のブロック図である。図1において、PND10は、記憶部11、外部入力部12、スピーカ13、画像表示部17、タッチパネル18、制御部20、GPS受信機23、ジャイロ25、メモリーカードスロット30、スイッチ31を備えている。
以下、別の実施の形態に係る表示装置について説明する。この実施の形態2に係る表示装置は、従来の静電容量型のタッチパネルを備えた表示装置は、装置を片手で保持する場合と両手で保持する場合とでは、タッチパネル近傍にとどまっている時のセンサ信号出力が異なり、それぞれに対応したタッチ操作を区別できなかったところ、操作者の指がタッチパネルにタッチする前にタッチパネル近傍にとどまった後のタッチ操作においても、簡単な構成で検出精度を高め、装置を片手で保持する場合と両手で保持する場合とのそれぞれに対応したタッチ操作を区別することができるタッチパネルを備えたものである。
この場合(車輌に搭載して使用する場合)、PND40の操作は、ダッシュボードなど特定の場所に固定されているため、操作者が意図してPND40を操作するとき意外は、PND40を操作者の指が覆ってしまうという状況は発生しない。
次に、本発明の実施の形態3について説明する。この実施の形態に係る表示装置は、従来、小型の表示装置を片手で保持しながらタッチパネルに入力操作を行うことを考慮した場合、表示装置を保持した手や指の近傍に、表示装置の機能を実行させる操作アイコンを配置することができないところ、操作者の指がタッチパネルにタッチする前にタッチパネル近傍にとどまった後のタッチ操作においても、簡単な構成で検出精度を高めることができ、特に小型あるいは携帯型の表示装置を片手で保持しながら操作する際の操作性を向上させるタッチパネルを備えたものである。
先ず、PND50がスタンド81に取り付けられている場合(据置操作モード時)の動作を説明する。
次に、本発明の実施の形態4について説明する。この実施の形態に係る表示装置は、従来、タッチパネルを備えた表示装置を車載用機器に応用した場合、この表示装置以外の車載機器に対する操作機器が運転席やダッシュボード付近に集中するため、タッチパネルを備えた表示装置付近をユーザの手や腕が横切ることが多々あり、タッチパネル付近の静電容量の変化が著しく、表示装置の誤動作を多く招くことが懸念されていたところ、操作者の指がタッチパネルにタッチする前にタッチパネル近傍にとどまった後のタッチ操作においても、簡単な構成で検出精度を高めることができ、特に車載機器に適用しても、誤動作を低減することができるタッチパネルを備えたものである。
このように、概略の動作が説明される本実施の形態のPND60について、以下にその詳細な動作説明を示す。
