Explanation
A tracking system that uses cameras on the headset rather than external sensors.
Real-world example
The cameras on the VR headset that see the room instead of requiring separate tracking towers.
Practical applications
- Simplified deployment: no sensor installation required in the room
- Total mobility: use the headset in any space
- Instant setup: power on and play, no complex calibration
- Reduced cost: no external equipment to purchase
Inside-out vs outside-in
Inside-out (cameras on the headset)
- The headset "sees" the environment
- Calculates its position through visual analysis (SLAM)
- Standard on modern headsets (Quest, Pico...)
Example: Meta Quest: 4–6 cameras built into the headset
Outside-in (external stations)
- Fixed sensors in the room look at the headset
- More accurate, no headset occlusion
- Permanent installation required
Example: SteamVR Lighthouse, PlayStation Camera
VR scenario
A company deploys 50 Quest headsets across its regional offices. Each site can start immediately: no installer, no wiring, no technical support. Inside-out tracking makes this mass deployment possible.
Why it matters in professional VR
- Inside-out tracking has democratized VR by eliminating installation complexity
- A decisive criterion for multi-site or mobile projects
- Quality is now comparable to outside-in for most use cases
