Brain-Computer Interfaces (BCIs) are innovative technologies that allow direct communication between the brain and external devices. They work by detecting brain signals and translating them into commands that can control computers, prosthetics, or other machines. This technology has the potential to help people with disabilities regain control over their movements or communicate more effectively. Researchers are exploring various applications for BCIs, including assisting those with neurological disorders or enabling virtual reality experiences. As the technology advances, it could lead to new ways for humans to interact with machines, enhancing our capabilities and improving quality of life for many individuals.
