This is one of the best Augment Reality demo that I have seen. It is fast to detect (after the initial detection) and it can detect multiple objects.
Sony SmartAR can show objects in 3D space. In one of the demo, it demonstrated the multiple object tracking. For example, when balls come out from the cup, they can be blocked by the books. The AR is clever to identify the book and task, able to simulate the bouncing off.
