The connection between the brain and technological equipment is mediated through brain–computer interfaces (BCIs), also known as mind–machine interfaces (MMIs). Stroke and amyotrophic lateral sclerosis (ALS) cause paralysis, making it impossible for those affected to interact with the outside world. Therefore, the BCI system could help these people lead better lives. The chapter details the design and execution of a brain–computer interface system that can be used to operate a wheelchair, turn on lights and fans, send an SOS text message, and more. The user may steer the virtual wheelchair in four different ways now: left, right, forward, and backward. The wheelchair may also be trained to traverse the user’s home, and once there, he or she can choose their destination with a simple blink of the eye. The Neurosky Mind wave headset was used to accomplish the feat. The numerous tasks in the system are executed using parameters such as attention, meditation, and eye blink values, all of which are generated by the headset. You can toggle between the three functions with a blink of your eye. The headset records the user’s brainwaves and transmits them to a computer through Bluetooth that is built into the headset. The computer then processes the data and uses it to control other devices, as specified in the code.
