Project Tango technology brings a new kind of spatial perception to the Android platform by adding advanced computer vision, image processing, and special vision sensors. Applications built with Project Tango include phone-based measuring and surveying, augmented-reality games tied to the physical environment, remoteshopping apps that visualize products in your home, accurate indoor navigation in stores and malls, educational experiences that allow users to walk through the solar system, real-time 3D reconstruction, and more.
