A: Halliday G2 Glasses and Halliday DigiWindow Glasses are designed with different displays and AI capabilities to meet different user needs. Halliday G2 features a waveguide optical system with dual Micro-LED projectors, delivering a more natural viewing experience. Compared with the display technology used in Halliday DigiWindow Glasses, the new display technology offers a wider field of view (FoV) and a larger viewing zone—the range of eye positions where you can still see the complete image. That means no matter your face shape, nose bridge height, it's easier to see a clear picture without constant readjustment.

Halliday G2 also introduces Meeting Flow, an AI-powered meeting system exclusive to Halliday G2, designed to make meetings and conversations smarter and more efficient. It helps you capture important decisions, follow discussions, get instant information when needed, and automatically organize meeting notes after the session.
