Claims (1)
- 操作面に対する物体の近接状態に応じた変量を出力する検出手段と、
前記変量に基づき前記物体の接触領域および接触位置を算出し、前記接触領域の空間特性と所定の判定条件に基づき前記接触領域が指先によるものかパームによるものかを判定するパーム判定機能を有する制御手段を備えたタッチパッドであって、
前記制御手段は、
前記接触位置が前記操作面の周辺部であるときは、前記接触領域の面積または長さに対応する空間特性が所定の面積又は長さに対応する第1条件を超えるときに前記接触領域はパームによるものと判定するとともに、前記空間特性が前記第1条件を超えないときに前記接触領域は指先によるものと判定し、
前記接触位置が前記操作面の中心部であるときは、前記空間特性が前記第1条件よりも大きい面積又は長さに対応する第2条件を超えるときに前記接触領域はパームによるものと判定するとともに、前記空間特性が前記第2条件を超えないときに前記接触領域は指先によるものと判定することを特徴とするタッチパッド。
