论文摘要
本文提出了通过电动图（EOG）信号基于大脑计算机接口的高效且可行的轮椅控制系统的进步。该系统利用眼睛的运动作为控制轮椅运动的目的元素。将皮肤表面电极放置在皮肤上，以获取电动图信号，并借助差分放大器，在参考和感兴趣点之间测量了生物电位，然后将这些获得的低电压脉冲放大，然后通过Sallen-Keye滤光片通过Sallen-Keye滤光片进行噪声和平滑。然后将这些脉冲收集到微控制器上。基于这些脉冲，电动机切换到右侧或左侧的移动。开发和测试了原型系统。该系统显示出令人鼓舞的结果。进行的测试显示，在正确方向上运动效率为99.5％。
This paper presents advancement towards making an efficient and viable wheel chair control system based on brain computer interface via electro-oculogram (EOG) signals. The system utilizes the movement of eye as the element of purpose for controlling the movement of the wheel chair. Skin-surface electrodes are placed over skin for the purpose of acquiring the electro-oculogram signal and with the help of differential amplifier the bio-potential is measured between the reference and the point of interest, afterwards these obtained low voltage pulses are amplified, then passed through a sallen-key filter for noise removal and smoothening. These pulses are then collected on to the micro-controller; based on these pulses motor is switched to move in either right or left direction. A prototype system was developed and tested. The system showed promising results. The test conducted showed 99.5% efficiency of movement in correct direction.
