BB Way Finding

BLACK BOX NETWORK SERVICES INDIA PRIVATE LIMITED

About this app

BB Wayfinding brings precise indoor navigation to any registered facility —
no internet GPS required. Simply open the app, pick your destination, and
follow a live "you are here" dot with turn-by-turn voice guidance straight
to where you need to go.

━━━━━━━━━━━━━━━━━━━━━━━━━
🔵 LIVE INDOOR POSITIONING
━━━━━━━━━━━━━━━━━━━━━━━━━
Your position is calculated on-device in real time by fusing three sources:
- BLE beacons installed throughout the facility
- Your phone's step detector for dead-reckoning between beacons
- Compass heading to track the direction you're walking

The result is a smooth, accurate dot that follows you as you move — even in
areas with sparse beacon coverage.

━━━━━━━━━━━━━━━━━━━━━━━━━
🗺 FLOOR PLAN & ROUTING
━━━━━━━━━━━━━━━━━━━━━━━━━
- Detailed, zoomable floor plan for every registered floor
- Tap any room, desk, or point of interest to instantly compute a walking route
- Dijkstra-based shortest-path routing along the building's walkable graph
- Route snaps to the path — the dot stays on the corridor, not cutting through walls
- Automatic rerouting if you leave the planned path

━━━━━━━━━━━━━━━━━━━━━━━━━
🔊 VOICE TURN-BY-TURN GUIDANCE
━━━━━━━━━━━━━━━━━━━━━━━━━
- Spoken instructions: "Turn left", "Bear right", "Arrive at Reception"
- Announcements are timed to the dot you see on screen — no early or late calls
- Voice guidance can be toggled on or off from Settings at any time

━━━━━━━━━━━━━━━━━━━━━━━━━
🏢 MULTI-FLOOR SUPPORT
