Your next screen might sit on your nose. Here's what's inside it.
Samsung's leaked Galaxy Glasses app points to camera controls, on-glass AI, and gesture input from a Galaxy Watch or Ring. Tap a component — it lights up on the model. Drag to spin the glasses.

The bigger picture
Why gestures come from your wrist and finger
Cameras can't always see your hands, and voice is awkward in public. A watch's IMU or a ring's motion sensors detect pinches and wrist-turns with milliwatt power budgets — Samsung's leak describes exactly this Watch + Ring integration, and Meta's Neural Band does it with EMG (reading motor-nerve signals electrically).
The battery problem nobody has solved
A phone budget is ~15 Wh; glasses have room for roughly 1–2 Wh split across the temples. That's why current products either skip displays entirely (audio + camera only), offload compute to your phone, or last 4–6 hours of mixed use. Every gram matters too: comfortable all-day glasses need to stay under ~50 g.
Display: why "waveguide" is the magic word
A tiny microLED projector in the temple fires light into a transparent etched lens layer that bends it into your eye — the waveguide. It's how you get a floating HUD without blocking the world. Efficiency is brutal: often under 1% of projector light reaches the pupil, which is why bright outdoor use is the hard frontier.
Why 2026 is the land-grab year
Ray-Ban Meta proved demand (millions sold). Google is shipping Android XR, Samsung's One UI XR extends its ecosystem lock-in, Apple is reportedly building toward glasses after Vision Pro. Whoever owns the OS on your face owns the next app store — this is the smartphone platform war replaying at eye level.
