Paralysis patients, particularly those with amyotrophic lateral sclerosis (ALS), gradually lose the ability to speak because of muscle loss. Even communication through gestures becomes difficult as their condition progresses. Eventually, the only means of communication left is eye movement. Using electrooculogram (EOG) signals, it is possible to improve the communication abilities of those patients who can move their eyes. We examined whether blinking could be detected from the back of the head in a noncontact manner using an in-pillow cloth electrode. We conducted an experiment aimed at detecting blinks in five subjects. The results revealed the possibility of measuring the change of potential related to blinks, with average sensitivity of 96%. This suggested the possibility of establishing a simple tool for ALS patients and paralysis patients to communicate through blinking.
瘫痪患者，尤其是肌萎缩侧索硬化症（ALS）患者，由于肌肉萎缩会逐渐失去说话能力。随着病情发展，即使通过手势交流也变得困难。最终，剩下的唯一交流方式就是眼球运动。利用眼电图（EOG）信号，可以提高那些能够移动眼睛的患者的交流能力。我们研究了是否可以使用枕内布电极以非接触方式从后脑勺检测眨眼。我们进行了一项旨在检测五名受试者眨眼情况的实验。结果显示，测量与眨眼相关的电位变化具有可能性，平均灵敏度为96%。这表明有可能为ALS患者和瘫痪患者建立一种通过眨眼进行交流的简单工具。
