Intelligent wheelchair control system based on BCI and the image display of EEG

Abstract

The intelligent wheelchair control system is built by single chip microcontroller and brain computer interface technology. Based on the application of EEG data is mainly purpose about this design. Firstly, TGAM chip as the core of production of EEG acquisition device - portable headset equipment, achieved EEG data acquisition; Secondly, connecting computer with EEG acquisition device by Bluetooth module, the acquisition of EEG raw data is transmitted to the computer, make use of the eSense algorithms accomplish EEG data quantized; Thirdly, control command is obtained according to processing, control command is transmitted to MCU which control the wheelchair; Finally, MATLAB's GUI functions to achieve EEG image display, compared to the image display of single programming language, the paper proposed multi-language mixed programming method, multi-language mixed programming method better display the three-dimensional image of the EEG.
