A Cursor Control Based Chinese-English Brain-Computer Interface Speller
نویسنده
چکیده
In this work, we developed a Chinese-English brain-computer interface speller based on 2-D cursor control. We built the English speller by integrated a motor imagery based 2-D cursor control strategy with a three-layer interface and combined the Pinyin input method with English speller to input Chinese characters. The online experimental results demonstrated that three subjects achieved good performance.

Brain Computer Interface (BCI) speller is a typical BCI-based application to help paralyzed patients express their thoughts. This paper proposed a novel motor imagery based BCI speller with Oct-o-spell paradigm for word input. Furthermore, an intelligent input method was used for improving the performance of the BCI speller. For the English word spelling experiment, we compared synchronous cont...
متن کاملA Chinese Text Input Brain-Computer Interface Based on the P300 Speller
A visual speller is a brain–computer interface that empowers users with limitedmotor functionality to input text into a computer by measuring their electroencephalographic responses to visual stimuli. Most prior research on visual spellers has focused on input of alphabetic text. Adapting a speller for other types of segmental or syllabic script is straightforward because such scripts comprise ...
