An Electronic Device to Aid the Physically Challenged People using Brain Waves

Brain computer interface is a technique used to capture the emotions and thoughts of a brain activity using Electroencephalogram(EEG). So it is useful to communicate with humans.In this paper, it deals with a Neuro sky mind wave to detect the signals for physically challenged people. If the brain activity of a signal and already attained signals are matched it displayed on the PC then it converted into an audible signal.
