Brain-Computer Interface (BCI), also known as Brain-Machine Interface (BMI), is a revolutionary technology that establishes a direct communication channel between the human brain and external devices. By capturing and decoding neural signals, BCI enables users to control computers, prosthetic limbs, or even drones with their thoughts, bypassing traditional neuromuscular pathways.
The core of BCI involves three key processes: signal acquisition (via EEG, fMRI, or implanted electrodes), feature extraction (using machine learning algorithms), and command translation (converting brain activity into device instructions). This technology has demonstrated transformative potential in healthcare, such as restoring mobility to paralyzed patients through robotic exoskeletons, and in entertainment, where it allows immersive gaming experiences controlled by mental commands.
Recent advancements include China’s approval of new medical BCI standards in March 2025 to accelerate industry growth, while companies like Neuralink continue to push the boundaries with invasive implants that enable users to type text or play video games using only their minds. As BCI evolves, it promises to enhance human capabilities across various sectors, from education to industrial automation
