Using the force of thought to control the earth might appear like a thing removed from sci-fi books. Be that as it may, the advancements we see today were once sci-fi beginning from man arriving on the moon to examine in teleportation. Thus controlling the surroundings through musings is likewise one of the apexes of that development called Brain Computer Interface. Utilizing cerebrum waves measured of an EEG to control PC. The contemporary remote control is supplanted by the force of one's idea which couldturn considerations into reality. The application ranges from utilizing contemplations to play diversions to re-wiring of the brain.The numerous unending potential outcomes extrapolated from this innovation could be of Controlling prosthetic appendages, robots, PC and practicing the cerebrum to rewire itself in stroke patients. The thought of this is basic, utilizing the typical EEG estimation that distinguishes the electrical yield of the cerebrum and utilizing them as a data to different gadgets As no persons contemplations are same; this framework gives distinction to the one utilizing it. Deadened patients who can't utilize their appendages and persons experiencing 'secured disorder' whose cerebrum action are all the same can connect utilizing this kind of non intrusive BCI. This paper is a tricky study that considers in the domain of this advancement distinguishing both its advantages and disadvantages as it prompts another time of savvy advances for what's to come.
