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.

Tango Tablet Development Kit Depth Test

The depth sensor is an important part of your Tango Development Kit. Its input is more complex than the input from a camera; we recommend that you run a depth test to familiarize yourself with some of the depth sensor's features.

Preconditions

  1. Verify that your device has the latest build. Go to Settings › System › About tablet › Build Number and verify your Build Number reads KOT49H.161004 and your Kernel Version date reads Tue Oct 4 (with or without time of day). If so, jump to step 2. If not, update your tablet's build with the following steps:
    • Initiate your OTA update. Go to Settings › System › About tablet › System updates.
    • On the Project Tango Update page, click Restart & Install.
    • To confirm that your device is up-to-date, go to Settings › System › About tablet › Build Number and verify your Build Number now reads KOT49H.161004 and your Kernel Version date reads Tue Oct 4 (with or without time of day). You can also click System Updates; if your system is up-to-date, you will see a message on the screen telling you so.
  2. Download the latest Tango Explorer app from the Play Store.
  3. Make sure the camera cover glass is clean and doesn’t have any visible scratches or fingerprints.
  4. For best results, the device should not be hot when running the test. If your device is hot, consider turning it off for 30 minutes or so before proceeding with the test.

Run the depth test

Find a suitably large wall, ideally with a clean and matte surface at least 6.5 feet (2 meters) wide and 4 feet (1.2 meters) tall, as in this picture:

  1. Position yourself at a distance of about five feet (1.54m) from the wall.
  2. Launch the Tango Explorer app and do the following things to get into the proper mode:
    • Select “Point Cloud” mode from the three options in the left bar (if the bar goes away, you can bring it back by tapping "Tango Explorer").
    • Select “First Person” view by tapping the appropriate box in the bottom right corner.
    • Tap on “Show Diagnostics” in the upper right part of the screen.
  3. Adjust the device so that the back camera glass is parallel to the wall; an easy way to achieve that is to tilt the device so that the depth point cloud appears on the screen as a rectangle with equally sized sides.

  4. Finally, hold the device steady with both hands, and you should start to see a Point Cloud that looks similar to the image above.
