🤔 What Are Brain-Computer Interfaces?
BCIs are systems that translate brain signals into digital commands. These interfaces read electrical activity in the brain and send it to a computer, allowing users to control external devices using only their thoughts. 🧠💡
🔬 How Do BCIs Work?
1️⃣ Signal Detection – Electrodes placed on the scalp (non-invasive) or inside the brain (invasive) detect neural activity. ⚡
2️⃣ Signal Processing – AI algorithms interpret brain signals and convert them into commands. 🖥️
3️⃣ Device Control – The processed data is used to perform an action, like moving a cursor or controlling a robotic arm. 🦾
🏥 Applications of Brain-Computer Interfaces
BCIs have the potential to transform multiple industries, from healthcare to entertainment. Let’s look at their most promising uses. 🔍
