PROBLEM TO BE SOLVED: To provide an eyewear imposing no burden on a users skin and providing no uncomfortable feeling.SOLUTION: An eyewear includes: a frame 120 a pair of nose pads 140 a first electrode 152 and a second electrode 154 that are provided on the respective surfaces of the pair of nose pads and can detect eye potential a third electrode that is provided on the surface of a bridge 124 of the frame and can detect the eye potential and a unit that detects the right-eye potential V1 as the potential of the first electrode with the third electrode 156 used as a reference and left-eye potential V2 as the potential of the second electrode with the third electrode used as a reference, (i) when V1+V2 is negative and V1-V2 is substantially zero, determines that the visual axis is turned up, (ii) when V1+V2 is positive and V1-V2 is substantially zero, determines that the visual axis is turned down, (iii) when V1+V2 is substantially zero and V1-V2 is negative, determines that the visual line is turned to the right, and (iv) when V1+V2 is substantially zero and V1-V2 is positive, determines that the visual line is turned to the left.COPYRIGHT: (C)2015,JPO&INPIT【課題】使用者の皮膚に負担をかけず、不快感を与えないアイウエアを提供する。【解決手段】フレーム120と、一対のノーズパッド140と、一対のノーズパッドのそれぞれの表面に設けられ、眼電位を検出可能な第1の電極152及び第2の電極154と、フレームのブリッジ124の表面に設けられ、眼電位を検出可能な第3の電極と、第3の電極156を基準とした第1の電極の電位である右眼の眼電位V1および第3の電極を基準とした第2の電極の電位である左眼の眼電位V2を検出し、(i)V1+V2が負であり、V1-V2が略ゼロの場合に視線が上に向けられたと判断し、(ii)V1+V2が正であり、V1-V2が略ゼロの場合に視線が下に向けられたと判断し、(iii)V1+V2が略ゼロであり、V1-V2が負の場合に視線が右に向けられたと判断し、(iv)V1+V2が略ゼロであり、V1-V2が正の場合に視線が左に向けられたと判断する。【選択図】図1
