This paper is about the analysis of different subdomains of Brain-Computer Interface (BCI) and its applications in day to day life. BCI allows for communication by brain activity without involving the muscular movement. This technology uses the signals from the brain and uses it to perform an outside activity like move wheelchair, robot arm, etc. If an individual wishes to do an activity like moving cursor then neurons capture the signal for this particular activity from the brain and then afterward, these signals are transferred to the finger, and now the individual can move the cursor. With the help of BCI, signals are directly transferred to a device where decoding is achieved, and one can quickly move the cursor. Thus it can be beneficial in case of physically challenged people. The day to day activities of a physically challenged individual will be at ease, which is the primary motivation to develop the particular BCI domain application. Brain-Computer Interface is achieved by invasive techniques like inserting electrode directly into one's brain by surgical methods. These surgical procedures are quite expensive, so there is a scope for future development in non- invasive domain so that everyone can take benefit of this technology. This paper also describes another subdomain of BCI Magnetoencephalography (MEG) which provides a signal with higher resolution than EEG, and thus the efficiency of the entire system can be increased exponentially.

Brain-computer interface (BCI), invasive brain-computer interface, partially invasive brain-computer interface, non-invasive brain-computer interface, electroencephalography, electrocorticography.
