Brain Computer Interface

        Brain computer interfacing is the maturing technology for the interfacing human brain to the computer. It is a method of commutation based on the neural activity generated by the brain and independent of its normal pathway of peripherals and muscles. The neural activity used in the Brain Computer Interface(BCI) can be recorded using invasive and noninvasive techniques. The goal of BCI is not to determine the person’s intention by strictly listening brain activity but allow the user to interact with the device. The potential of brain computer interfacing systems for helping handicapped people is obvious. There are many computer interfaces designed for the disabled persons. Most of these are require some sort of reliable muscular control such as neck, head, eyes, or other facial muscles.

BCI means Brain computer interface, It  is a communication pathway between humans brain to computer. Basic need of Brain computer interfacing for the disabled person mean handicapped person such as hearing problem, visibility problem etc. It also used in daily life generally mouse, keyboard as input of the computer but by using brain computer interfacing connecting mind as input of the computer is possible. It is used for the writing on the document by using mind, speaking by mind (who cannot speak), and selecting function on computer such as copy file, pest file, and delete file.
