Brain Signal Processing: Technologies, Analysis and Application

Developing fields such as Brain Computer Interface, Virtual Reality are now a day's in research are using brain signal as an equipment for a good start to differentiate tasks. It created new break points in aiding wellness training, rehabilitation, games, education, entertainment etc. Here, the content has been summarized about the technology, which had been developed for acquisition of brain signal, then how those signals are analysed, its utility and its challenges. Previously many authors have discussed about various methods, its empirical analysis and its comparisons. This paper gives a crisp explanation about those analysis and focuses on EEG processing methods for communication system which will be useful in multiple fields.
