Nerval's Lobster writes "Google's Advanced Technology and Projects Group is working on a new initiative, Project Tango, which could allow developers to quickly map objects and interiors in 3D. At the heart of Project Tango is a prototype smartphone with a 5-inch screen, packed with hardware and software optimized to take 3D measurements of the surrounding environment. The associated development APIs can feed tons of positioning and orientation data to Android applications written in Java, C/C++, and the Unity Game Engine. In addition to a 'standard' 4-megapixel camera, the device features a motion-tracking camera and an aperture for integrated depth sensing; integrated into the circuitry are two computer-vision processors. Google claims it only has 200 developer units in stock, and it's willing to give them to independent developers who can submit a detailed idea for a project involving 3D mapping of some sort. The deadline for unit distribution is March 14, 2014. In theory, developers could use ultra-portable 3D mapping to create better maps, visualizations, and games. ('What if you could search for a product and see where the exact shelf is located in a super-store?' Google's Website asks at one point.) The bigger question is what Google intends to do with the technology if it proves effective. Google Maps with super-detailed interiors, anyone?"
