Researchers found a way to tuck AR objects behind real ones

Current AR technology does a pretty decent job of placing a virtual image in front of an actual one, but blocking a virtual image with a real object is actually quite difficult and something that available head-mounted augmented reality displays can't do yet. But MIT Technology Review reports that University of Arizona researchers have developed a prototype system that can do just that.

The project was led by Hong Hua, a professor in the College of Optical Sciences, and she told MIT Technology Review that trick is getting precise control of the real-world light. Her prototype does this with a series of lenses and mirrors, not totally unlike a telescope. In the image above you can see a digital teapot is sitting both in front of a can of compressed air and squeeze bottle as well as behind a can of spray paint. With this prototype, Hua's goal was to make it as inexpensive as ...
