🧭 What navigation in smart glasses does

It helps you get directions in real time while you’re walking, biking, or driving.

📍 1. Turn-by-turn directions (HUD style)

Smart glasses can show or say:

• 👉 “Turn left in 200 feet”
• 👉 Arrows floating in your view
• 👉 Street names and route info

You don’t need to open maps on your phone.

🗺️ 2. Real-world overlay (AR navigation)

More advanced glasses can:

• Overlay arrows directly on the street
• Highlight your route in real space
• Show where to walk step-by-step

👉 It feels like directions are “painted” onto the real world.

🤖 3. Voice-guided navigation

Even without a full display, AI glasses can:

• Speak directions through audio
• Update you as you move
• Re-route you if you miss a turn

Example:

“Walk straight for 5 minutes, then turn right.”

📡 4. Live GPS tracking

Navigation features usually include:

• Real-time location tracking
• Distance remaining
• Estimated arrival time
• Traffic-aware updates

🚶 5. Hands-free safety benefit

This is a big advantage:

• No need to look at your phone while walking
• Keeps your eyes on the road or surroundings
• Safer for biking or busy areas
