What is Project Tango?

Project Tango is a Google technology platform that uses computer vision to enable mobile devices, such as smartphones and tablets, to detect their position relative to the world around them without using GPS or other external signals. Project Tango technology gives a mobile device the ability to navigate the physical world similar to how we do as humans. Project Tango brings a new kind of spatial perception to the Android device platform by adding advanced computer vision, image processing, and special vision sensors.

Project Tango is different from other emerging 3D-sensing computer vision products, such as Microsoft Hololens, in that it's designed to run on a standalone mobile device and chiefly concerned with determining the device's position and orientation within the environment.

The software works by integrating three types of functionality:

    Motion-tracking:

 using visual features of the environment, in combination with accelerometer and gyroscope data, to closely track the device's movements in space
    Area learning: storing environment data in a map that can be re-used later, shared with other Project Tango devices, and enhanced with metadata such as notes, instructions, or points of interest

    Depth perception: 

detecting distances, sizes, and surfaces in the environment Together, these generate data about the device in "six degrees of freedom" (3 axes of orientation plus 3 axes of motion) and detailed three-dimensional information about the environment.

Applications on mobile devices use Project Tango's C and Java APIs to access this data in real time. In addition, an API is also provided for integrating Project Tango with the Unity game engine; this enables the rapid conversion or creation of games that allow the user to interact and navigate in the game space by moving and rotating a Project Tango device in real space. These APIs are documented on the Google developer website.
