Over the past decade, many laboratories have begun to explore brain computer interface (BCI) technology as a new communication option for those with neuromuscular impairments that prevent them from using conventional augmentative communication methods. This work outlines the potential benefits of BCI, summarises a number of developments which have been made in recent years and provides an overview of the fundamental requirements which must be acknowledged for the successful progression of BCI technology. A novel proposal for a unique BCI system is also detailed
