Mind-Media System: A Consumer-Grade Brain-Computer Interface System for Media Applications

Brain science has made many achievements in the media area. However, the brain-computer interface (BCI) is not yet available to the general public because of the cost of the equipment. This paper investigates a consumer-grade brain-computer interface system for media applications, which only cost $45. By the electroencephalogram (EEG) processing method studied in this paper, the EEG signals corresponding to different commands can be identified so that subjects could control the media by their mind without any body movements. The validation experiment on music players demonstrates the effectiveness of our mind-media system.
