Introducing Project Tango Area Learning
May 18, 4:00 PM - 5:00 PM / Stage 1 | Hercules  (PST) 

Motion tracking on a mobile device has already enabled a whole new range of experiences, but what would be possible if your Project Tango device could have a memory? With Area Learning, Project Tango can not only see the space around you, but it can also remember the space around you. This opens up a new range of possibilities for Project Tango developers - attach virtual objects to the world that remain in place even when you restart an app, design multiplayer experiences and know the exact location of each player, pause/resume AR/VR experiences, and eliminate motion tracking drift.

Tango devices will be made available next month. 
Further announcements to be made here on May 18 at 3 PM PST.
