Brain-Computer Interfaces (BCIs): How They Work, Real-World Applications, Challenges & Ethics
Brain-computer interfaces (BCIs) are reshaping how people interact with machines, with applications spanning medical restoration, assistive technology, and experiential augmentation. At their core, BCIs translate neural activity into commands — capturing brain signals, decoding intent with algorithms, and delivering output to a device or environment. Understanding the different approaches, capabilities, and remaining hurdles helps separate […]
