Tango Vertigo is an application that allows users to peer into virtual worlds via augmented reality. This app utilizes Google Tango's integrated depth sensing and motion tracking to reveal an underground world in front of the user that may be observed from all angles. An unobstructed 3 meter by 3 meter space is preferred with a minimum unobstructed 1.5 meter by 1.5 meter space recommended. Users may touch and drag to re-locate the virtual world as well as pinch to zoom. A larger area provides a more immersive sensation. A Tango enabled device is REQUIRED. We recommend the Lenovo Phab 2 Pro with Tango for the best experience.
