摘要
为有运动功能障碍的残疾人设计了一个实时的脑机接口网络浏览器,该系统能够通过采集被试者的大脑皮层脑电信号,对其进行分析并将结果作为浏览器的一种输入装置,从而实现通过人的思维活动来浏览网页的基本功能。文章主要介绍基于视觉诱发电位的脑机接口对网络浏览器的控制。该类型的脑机接口利用的是人在注视固定频率闪烁物体时产生的稳态视觉诱发脑电信号,将其转化为3个控制信号,然后作为一个专用网络浏览器的输入控制信息,从而实现使用浏览器的功能。
A real-time brain-computer interface web browser was designed for the disabled with motor dysfunction. By collected subjects’ electroencephalogram (EEG) signal of the cerebral cortex, the system can analyze it to a result as the input control signal of web browser, and then people can visit the website through their thinking. The article introduces the visual evoked potential-based brain-computer interface for the web browser control. The type of brain-computer interface is the use of fixed frequency in the monitor blinking objects generated EEG steady-state visual evoked its into three control signals, and then as a dedicated web browser control information input to achieve use browser’s functionality.
