Google Tango is enabling technology for devices to understand their position relative to the world around them. Tango's computer vision platform empowers developers creating next-generation spatially aware application experiences. This workshop explains the Tango hardware and software platform, the technologies in use, how they work, and how to use them. The session will prepare developers to use Tango via the C, Java and Unity SDKs, and conclude with a worked example of building a Tango-enabled Augmented Reality application using Unity. A limited number of Tango Development Kit devices will be available for attendees use.
