中文摘要: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。

Research and Implementation of High Performance BCI Typewriter Based on P300

Abstract: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 flicker, 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 typewriter. Provide some necessary reference basis for the application of the future BCI system induced interface application.
