As a novel form of the brain-computer interface （BCI）, the online/offline EEG data may be interpreted through its auditory representation which can be considered as a specific tool in EEG monitoring and analysis. In this work, after a comprehensive comparison of the various designs of brainwave music generations, a waveform event mapping system for music display in real time-- the Chengdu Brainwave Music （CBM） is proposed, which is a special on-line BCI system. In CBM, the user datagram protocol （UDP） is adopted to transport EEG data from the recorder to a music generator. The CBM could possibly be used as an audio feedback tool in BCI, or a monitoring tool in clinic EEG, and a subject specified music therapy method.展开更多
