| Abstract: | Currently there has been merely two types of input methods used in the proposed Chinese-based BCI input system:Pinyin input and stroke input.Furthermore,both of them cannot overcome the problems such as low Chinese input rate and being unportable.To solve the problems,a Wubi Chinese input system is proposed on the basis of P300.This system use the low-cost OpenBCI suite,use the Wi-Fi protocol to transmit computer data,the stimulation interface is realized on mobile devices,and Convolutional Neural Network is used to process EEG signal.The experimental results show that the system has the characteristics of high Chinese input rate,high accuracy and portability. |
