Cognitive accessory combining brain-computer interface and smart glasses

Abstract

The present invention relates to wearable smart devices and neural engineering, disclosing a cognitive accessory that combines a brain-computer interface (BCI) with smart glasses, which includes an in-ear electrode module equipped with a plurality of EEG electrodes, a smart glasses frame with temples on both sides, a nose pad at the bottom of the frame, and two lenses installed on the frame. The smart glasses frame integrates a non-invasive brain signal acquisition module, an environmental perception module, an embedded processor, and an AR display module. The brain signal acquisition module uses flexible electrodes distributed inside the nose pad and the temples. By integrating flexible EEG electrodes and miniature fNIRS probes within the smart glasses frame, users can achieve efficient, non-invasive monitoring of brain electrical activity and cerebral blood oxygenation without wearing traditional complex headgear. This design makes the device more lightweight, comfortable, and convenient for long-term wear.
