Bringing together cameras, depth sensors, and a custom-designed co-processor inside a mobile device, Google’s Project Tango can display virtual-reality environments or lay computer graphics over the real world, either of which will sync with your physical movements as you hold the device. The technology can also be used to scan the interior of a room to generate a 3D-graphic model of it. Tango was initially demonstrated on Android smartphones with 5-inch screens. More recent public reveals have been shown on Android tablets with 7-inch screens.
A consumer device incorporating Tango technology by LG is set for release sometime in 2015. Whether it will be a smartphone or tablet is unknown as of this writing.
