1. A cognitive accessory combining a brain-computer interface (BCI) with smart glasses, comprising:
an in-ear electrode module (1);
a smart glasses frame (201), provided with temples (202) on both sides, a nose pad (204), and two lenses (203) installed on the frame, wherein the smart glasses frame (201) is provided with an embedded processor (4) disposed therein, and the embedded processor (4) integrates a non-invasive brain signal acquisition module (401), an environmental perception module (402), and an augmented reality (AR) display module (403); wherein
the brain signal acquisition module (401) uses flexible electrodes (205) distributed inside the nose pad (204);
the environmental perception module (402) comprises a binocular red-green-blue (RGB) camera (208) integrated on an upper edge of the smart glasses frame (201), motion sensors (3) embedded in the temples (202), and audio sensors (206) located on both sides of the smart glasses frame (201);
the binocular RGB camera (208) supports simultaneous localization and mapping (SLAM) environment modeling and eye tracking;
the motion sensor (3) comprises an accelerometer, a gyroscope, and a magnetometer, and the motion sensor (3) is configured for head posture compensation and motion artifact elimination;
the audio sensor (206) uses a directional microphone array to capture environmental sounds and separate user voice commands; and
an elastic hinge bracket (209) is provided between the temples (202) and the smart glasses frame (201), ends of the temples (202) are configured as elastic telescopic structures, and an impedance detection chip (207) is built into the temples (202) to adjust a pressure according to a user's head circumference, ensuring a contact impedance between the flexible electrodes (205) and skin is <10 kΩ.
