PROBLEM TO BE SOLVED: To provide an eyeball rotation detection device capable of detecting a right-left rotation of a right eyeball and a right-left rotation of a left eyeball individually.SOLUTION: A right temple electrode 32, a right nose pad electrode, a left nose pad electrode, a left temple electrode 36, and a neutral electrode are provided for detecting an eye potential. In order to detect convergence and divergence, the electrodes are arranged so as to sandwich the eyeballs from a longitudinal position which is in-phase (same vector) with respect to the right and left eyeballs, and a right and left position which is a reverse phase (reverse vector) with respect to the right and left eyeballs in the same plane.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】右眼球の左右回転と左眼球の左右回転を個別に検出できる眼球回転検出装置を提供する。【解決手段】眼電位を検出するために右テンプル電極３２、右ノーズパッド電極、左ノーズパッド電極、左テンプル電極３６、中性電極を設ける。輻輳・開散を検出するために、同一の平面内において、左右それぞれの眼球に対して同相（同じベクトル）となる前後位置、かつ左右それぞれの眼球に対して逆相（逆のベクトル）となる左右位置から眼球を挟むように電極を配置する。【選択図】図１
