Brain computer interfaces enables user to control devices with electroencephalographic activity from within the brain. The main goal of the BCI research is to develop intelligent interfaces that allow disabled users to communicate with nanorobots and others. The majority of BCI systems work by reading and interpreting cortically – evoked electro- potentials obtained the electroencephalogram data. A Brain computer Interface allows controlling a computer by brain activity only without the need for muscle. As the power of modern computer grows alongside our understanding of the human brain we move ever closer to making some pretty spectacular science into reality. A Brain computer sometimes called a direct neurol interface or Brain machine interface. Most current BCIs are not invasive. BCIs are slow in comparison with normal human because of the complicity and noisness of the signals used as well as the time necessary to complete reconcition and signal processing.BCI acts as direct control over the activities of all individual neurons by means of nanorobots.Arbitary reador write access to the whole brain. This technology is a method of communication based on voluntary neurol activity generated by the brain and independent of its normal output pathways of peripheral nerves and muscles.
