The range of your projection depends on what sensor you are using and how far away you can mount it from the projection surface.
Orbbec Astra or Orbbec Astra Pro
The maximum area that you can cover is around 17 ft x 15 ft (5 m x 4.5 m) with the sensor mounted 19.5 ft (6 m) above the projection surface.
Kinect for Xbox One
The maximum area that you can cover is around 19 ft x 16 ft (5.8 m x 4.8 m) with the sensor mounted 15 ft (4.5 m) above the projection surface.
Web Cameras are more flexible for distance, but they do not track as well and are not recommended for floor installations.
Is your display larger than 19 ft x 16 ft (5.8 m x 4.8 m)? Contact us about developing a custom software seaming solution for using multiple sensors.
