"Rather than using 2-D camera overlays, the app takes data from your phone''s camera sensors to map digital objects in a room. Apple calls this "world tracking," and it helps keep a digital sofa from skittering around the room like a balloon. The furniture items also load faster than they did in the previous iteration, and don''t require any calibration on the part of the user. By scanning the floor alone the app takes measurements"
Customer engagement and personalization Eliminates the need to take measurements and looking through manuals
