thought-controlled devices

Thought-controlled devices, also known as brain-computer interfaces (BCIs), enable direct communication between the brain and external equipment. They work by detecting electrical signals produced by neural activity—often via sensors placed on the scalp or implanted in the brain—and translating these signals into commands that operate devices like computers, prosthetics, or robotic systems. This technology allows users to control devices using their intentions or thoughts, improving independence for individuals with physical disabilities and opening new possibilities for human-computer interaction. Advancements continue to enhance accuracy, speed, and applicability across medical and technological fields.
