本文描述了一种基于眼电的机械臂控制技术。这项技术检测眼睛的运动，通过在眼睛周围放置电极来测量角膜和视网膜之间的电位差。解释了为获得用户眨眼时眼睛的位置而开发的处理算法。除方向外，处理算法的输出还提供四个不同的值(0到3)，以根据用户在一个方向上看的程度来控制机械臂的速度。这允许在眼睛运动的情况下控制机械臂的两个自由度。眨眼已经被用来在测试中标记一些目标。文中给出了在真实机械臂上的实验结果。
This paper describes a technique based on electrooculography to control a robot arm. This technique detects the movement of the eyes, measuring the difference of potential between the cornea and the retina by placing electrodes around the ocular area. The processing algorithm developed to obtain the position of the eye at the blink of the user is explained. The output of the processing algorithm offers, apart from the direction, four different values ( zero to three) to control the velocity of the robot arm according to how much the user is looking in one direction. This allows controlling two degrees of freedom of a robot arm with the eyes movement. The blink has been used to mark some targets in tests. In this paper, the experimental results obtained with a real robot arm are shown.
