Minimal Concrete Metaphors

  • Most things are an object
  • Image anchor is a group of objects
  • Geo anchor is a group of objects
  • Scene is a group of objects
  • Everything else is a ‘behavior’ with properties.

Edit in 2D, adjust in-situ

  • AR and VR are different than desktop views
  • You *must* test in the device you will deploy to
  • Make it easy to jump back and forth
  • Requires syncing
  • Requires ease of login or non-login
