“模拟阅读”脑-机接口刺激物样式对正确率的影响
Influence of the Patterns of Stimulus on Correct Rate in "Imitating Reading" Brain - Computer Interface
摘要
Abstract
This paper performs the experiments for imitating reading visual brain‐computer interface ,subjects’ EEG are recorded when they receives different patterns of stimulus ,and then the signals are classified into seven categories .The visu‐al stimulator is a virtual keyboard on the screen ,which displays seven buttons .In the experiment ,by changing the patterns of stimulus below the button(15 kinds) ,the seven subjects’ correct rate are estimated to find a pattern which makes the cor‐rect rate highest .The results show that the same subject’ accuracy in different patterns of stimulus are different and the high‐est accuracy of different subjects may also appeares in different patterns .Moreover ,the subject’ classification accuracy in no background character condition is higher than the background character case with the same target .关键词
