Abstract
【解決手段】眼の位置及び凝視方向を検知する際に、ディスプレー(1)の周囲に配置されたフォトセンサ(1)及び光源(2、3)と計算及び制御ユニット(6)とが使用される。光源の1つはセンサの周囲に配置され、内側と外側の素子(3'、3”)を含んでいる。内側の素子だけが照明された場合は、取り込まれた画像に強いブライト・アイ効果が得られ、その結果、瞳孔の簡単な検知、ひいては凝視方向の安全な決定が行われる。外側の素子及び外側の光源(2)だけが照明された場合は、フォトセンサから眼までの距離の決定が行われる。画像内の瞳孔の決定が可能になった後は、取り込まれた後続の画像内で眼の像が位置する瞳孔の周囲の領域だけが評価される。どの眼が左眼及び右眼であるのかは、目の画像を追跡し、連続的に取り込まれる画像内での眼の位置を評価することによって決定可能である。
