Eye tracking is the process of measuring either the point of gaze ("where we are looking") or the motion of an eye relative to the head.

观众面对这张照片时最多看的是身体的那些部位? 用"eye tracking"技术研究, 可以得出结论: "people almost always focus in on faces, breasts and genital areas", 脸部, 胸部, 生殖器.  男女观众都是这样.

把上述的测量过程 (测出你的眼睛注视的地方) 反过来, 变成一个控制过程: 让你的眼睛移向我指点的地方. 就是我说的“眼珠移动技术”.
