本文提出了一种基于脑电图信号P300波的脑机接口（130）鼠标。这个系统是类似的，因为在任何时候都不会对P300是否在对刺激的反应中产生做出二元决定。相反，屏幕上指针的二维运动，使用一种新颖的脑机接口模式，通过直接结合不同刺激下过滤器产生的输出幅度来控制。该过滤器和要在其中组合的特征通过进化算法进行优化。
In this paper we propose a brain-computer interface (130) mouse based on P300 waves in electroencephalogram (EEG) signals. The system is analogue in that at no point a binary decision is made as to whether or not a P300 was actually produced in response to the stimuli. Instead, the 2-D motion of the pointer on the screen, using a novel BCI paradigm, is controlled by directly combining the amplitudes of the output produced by a filter in the presence of different stimuli. This filter and the features to be combined within it are optimised by an evolutionary algorithm.
