Abstract: A communication device that does not depend upon the peripheral nerves and muscles i.e. totally independent from the traditional output pathways of nerves or muscles is known as BCI (Brain Computer Interface) or BMI (Brain Machine Interface). Without hand movement the BCI user is able to communicate with the external device e.g. computer. The people suffering from the severe palsy e.g. amyotrophic lateral sclerosis or brain stem stroke. For them BCI is way to communicate with the external environment. People by himself can accomplish requirements without need of a nurse who is actually revolving all around the patient’s bed all the time. The productions of signals help the users to manipulate the brain activity instead of using motor movements so that the user can use the signals to control the computer or any communicational device. So here a BCI device is launched where subject can able to open any browser without using any hand movement. The BCI measures the brain activity and translate into the control signal which acts as the input for the BCI applications. As the research in BCI has grown rapidly, it is showing renewed interest. A BCI is an artificial intelligence that recognizes a set of brain signals in the following stages: - Signal acquisition, pre-processing or signal enhancement, feature extraction, classification and control interface.
