6. Frequently Asked Questions (FAQ)

Q1: What is spatial computing?

Spatial computing is a technology paradigm that blends digital content and artificial intelligence into the physical 3D environment, allowing users to interact with digital information using gaze, gestures, and voice.

Q2: How do vision-language AI models work in smart glasses?

Vision-language models analyze the live camera video feed from the smart glasses, understanding physical objects, reading text, and answering user questions about what they are looking at in real time.

Q3: Are modern AI smart glasses heavy or bulky?

No. Thanks to diffractive micro-waveguides and high-density NPU silicon, modern smart glasses weigh under 70 grams—resembling standard stylish prescription eyeglasses.
