摘　　要：随着科技的发展,人们对于计算机能力的提高日益强大,从而推动了人机交互技术的不断发展。类似于传统的人机交互方式(键盘,鼠标,遥控器等),脑机接口(Brain Computer Interface,BCI)技术同样也可以被当作成一种人机交互方式。在字符输入中,以往的诱发界面常用6×6矩阵(26个字母加10个阿拉伯数字),并按照一定顺序排列并以横、列方式进行闪烁,然后利用P300来分析所输入的字符。本文按照字母出现频率不同以一定方式组合成不同的诱发界面,通过对比找出高性能的BCI打字机。为以后BCI系统诱发界面应用中提供一些必要的参考依据。With the development of science and technology, people for the improvement of computer ability is strong, so as to promote the ever-accelerated development of human-computer interaction technology. Similar to the traditional way of human-computer interaction （keyboard, mouse, remote controller, etc. ）, Brain Computer Interface （BCI） technology is also can be used as a way of human-computer interaction. In the input of characters, previous induced interface commonly used 6 x 6 matrix （26 letters and 10 Arabic numbers）, and according to certain order to arrange and use cross column mode to flick- er, then use P300 to analyze the entered characters. This paper, in accordance with the letters appear at a certain different frequency and in a certain way to combine different induced interface , by comparison to find high performance BCI typewrit er. Provide some necessary reference basis for the application of the future BCI system induced interface application.
