Portable Brain-Computer Interface, Quietly Arriving

Brain-computer interfaces (BCIs) are attempting to enter the consumer market through everyday hardware such as headphones and glasses. The article analyzes how companies like Bridge Neurotech, Neurable, Emot, and Looktech are integrating BCI technology into headphones, earbuds, and smart glasses, discussing the advantages and disadvantages of different signal acquisition methods (such as EEG and ultrasound). It also explores the challenges faced by consumer-grade BCIs in real-world applications, including signal stability, power consumption, and regulatory issues. The article also looks ahead to potential future directions for BCI technology, emphasizing its shift from 'being able to measure' to 'being able to use.'
