The control of computer functions by eye movements was demonstrated in 14 normal volunteers. Electrical potentials recorded by horizontal and vertical electrooculography (EOG) were transformed into a cursor that represented a moving fixation point on a computer display. Subjects were able to spell words and sentences by using eye movements to place the cursor on target letters in the display of an alphabet matrix. The successful demonstration of computer-controlled syntactic construction by eye movements offers a potentially useful technique for computer-assisted communication in special groups, such as developmentally-disabled individuals who have motor paralysis and who cannot speak.
14名正常志愿者展示了通过眼球运动控制计算机功能的过程。通过水平和垂直眼电图（EOG）记录的电位被转换为一个光标，该光标代表计算机显示屏上的一个移动注视点。受试者能够通过眼球运动将光标置于字母矩阵显示屏中的目标字母上，从而拼写单词和句子。通过眼球运动成功演示计算机控制的句法构建，为特殊群体（如患有运动性麻痹且无法说话的发育障碍个体）的计算机辅助通信提供了一种潜在有用的技术。
