Your phone can help you navigate from one side of the country to the other, help you share memories with friends, or even identify the song that's playing right now. But it can’t answer basic (and important) questions like, “Where’s the nearest building exit?” or “Will this couch actually fit in my apartment?” That’s because while your phone may know where you are in the world, it doesn’t know where you are in the room.

But, for the past three years, the Project Tango team has been working to help devices understand physical space and motion more like people do. Today we’re taking the next step with the first Tango-enabled phone (Lenovo’s PHAB2 Pro). We’re also graduating the effort from Project Tango to, simply, Tango.
