During a recent technology demonstration, Sony engineers showed off a striking application of a type of virtual reality that’s probably better known as “augmented reality.”

By overlaying 3D graphics onto the real world, a computer can make objects more informative, more useful or more entertaining. And in this case, Sony managed to turn the whole room into an augmented reality paradise with a lush tree canopy and birds flying overhead.

Sony’s latest augmented reality tech is different than other recent offerings in that it does not require a predetermined marker or place-holder to project 3D graphics onto the real world.

This video may be in Japanese, but you don’t have to understand a word to marvel at the technology being demonstrated.
