Navigation
Navigation gives you turn-by-turn voice directions to any destination. VISION uses your GPS location and routing to guide you step by step, with automatic warnings if you go off course.
How to Use
Start a route
Hold the button and say:
- “Navigate” or “Navigate to [place]”
Chinese: “导航”
VISION will ask you for the destination if you don’t say one, and confirm before starting.
During navigation
| Command | What it does |
|---|---|
| ”Full directions”, “Read all directions”, “All directions” | Reads out every remaining step |
| ”Current instruction”, “Next step”, “Repeat direction”, “Repeat” | Repeats the current step |
| ”Where am I”, “My location”, “Current location” | Announces where you are now |
| ”Where am I going”, “My destination” | Announces the destination |
| ”Cancel navigation”, “Stop navigation”, “End navigation” | Stops the current route |
Chinese equivalents: “完整路线”, “下一步”, “我在哪”, “当前位置”, “目的地”, “我要去哪”, “停止导航”, “取消导航”
Example Session
You: “Navigate to the pharmacy”
VISION: “Navigate to Guardian Pharmacy, 800 meters away. Walk north.”
(walking…)
VISION: “In a short distance, turn right.”
(you turn)
VISION: “Continue straight for 200 meters.”
VISION: “You’ve reached your destination.”
Safety Features
Off-route detection
If you stray too far from the planned route, VISION alerts you and recalculates:
“You’re off course. Recalculating route…”
Stationary check-in
If you haven’t moved for a while, VISION gently checks in:
“You’ve been stationary for a while. Do you need help?”
Session resume
If your glasses restart during navigation (like a battery swap), the active route resumes automatically on startup.
Favourite Locations
For places you visit often, save them in the mobile app then navigate by voice:
- “List favourites” — reads out your saved locations
- “Navigate to favourite” — starts a route; VISION asks which one
See Location Tracking & Favourites for details.
Caretaker Monitoring
While navigation is active, a linked caretaker can see your live progress on a map — including your route, current position, distance remaining, and estimated arrival time. See Caretaker Features for details.
