🧠 Brain-Computer Interface (BCI) Applications What is a Brain-Computer Interface (BCI)? A Brain-Computer Interface (BCI) is a technology that enables direct communication between the brain and an external device , bypassing traditional neuromuscular pathways. It records brain signals (usually via EEG, fNIRS, or implants) and translates them into commands for devices. 🔧 How BCIs Work (Simplified) Signal Acquisition: Captures brain activity using sensors (e.g., EEG caps or implants). Signal Processing: Filters and decodes the electrical signals into usable data. Translation Algorithm: Converts the processed signal into a control command. Output Device Interaction: Commands control a cursor, prosthetic limb, computer interface, or other systems. 🌍 Key BCI Applications 🧑⚕️ 1. Medical & Assistive Technology Use Case Description Neuroprosthetics Control artificial limbs or exoskeletons with thought. Communication Aids Enable speech or typing for paralyzed ...
