After Pierre Gloor and Hans Berger discovered the human electroencephalogram or EEG produced in the brain in 1969, brain computer interfaces (BCIs) became a reality. However, for more than a couple of decades, besides the common social fascination with such devices, they have not yet been considered as a feasible alternative interface for common daily activities. This is attributed to issues such as response time, costs and long initial user training periods. We define and outlines the current BCI technologies and reviews the current status of BCIs in the context of wearable computers. The use of augmented reality environments and the integration of wireless technologies such as Bluetooth are proposed as potential catalysts in the process of incorporating BCIs into daily life.
