The Tango project will be deprecated on March 1st, 2018.
Google is continuing AR development with ARCore, a new platform designed for building augmented reality apps for a broad range of devices without the requirement for specialized hardware.

In addition to working with our OEM partners on new devices, Google is also working closely with Asus, as one of our early Tango partners, to ensure that ZenFone AR will work with ARCore. We'll be back with more information soon on how existing and new ZenFone AR users will get access to ARCore apps.

Known Issues

Lifecycle

  • The current version of the Tango APIs are designed for a single app using Tango Service in the foreground. Multi-app usage is undefined so do not plan on users switching between multiple active Tango apps at this time.
  • Cameras will occasionally crash and cannot be opened. For Tango applications, when they start, the API call TangoService_connect() will always return an error after 10 seconds and the app cannot continue. A reboot is usually required when this happens.

Depth

  • Occasionally, or when under high CPU load, the depth flash may appear in the color image, or no depth points are returned. Let the device cool down and/or reboot.

Calibration

  • ADFs may become tilted with respect to gravity and you’ll find the horizon is no longer correct when relocalizing. You will need to delete the ADF and make a new one if this happens.

OS/Device

  • The default landscape device orientation is uncommon. Some existing apps, especially those built with Unity, may not rotate correctly. See One Screen Turn Deserves Another for more information.

Unity SDK

  • The VideoOverlay feature of the SDK does not work when multithread rendering is turned on.
