Brain-Computer Interface
A Brain-Computer Interface (BCI) is a direct communication pathway between the brain and an external device, enabling control or information exchange without using peripheral nerves or muscles. It typically involves measuring brain activity (e.g., via EEG, fMRI, or implanted electrodes), processing signals to interpret user intent, and translating it into commands for applications like prosthetics, communication aids, or entertainment systems. BCIs bridge neuroscience, engineering, and computing to assist people with disabilities or enhance human capabilities.
Developers should learn about BCIs when working on assistive technologies, neurotechnology, medical devices, or human-computer interaction projects, as they enable innovative solutions for paralysis, neurological disorders, or immersive experiences. It's crucial for roles in healthcare tech, gaming, robotics, or research labs focusing on neural engineering, where understanding signal processing, machine learning, and real-time systems is essential to build reliable and ethical interfaces.
