BuildAR Augmented Reality workshop 16th Oct 2012

  • Types of AR include location, image, now panoroma (maps onto sphere), and now 3D objects.
  • New AR also enables images, 3D objects
  • Basic model involves a HTML overlay, 3D scene cube, camera view at back.
  • Metaio (made by Junaio) powers Builder. Can have dozens of objects interacting with each other.
  • Range of different approaches to specifying coordinate systems – approach adopted by Junaio and hence BuildAR for location based AR is x axis runs west east, y-axis runs south north, z-axis runs up down.
  • Note locations can be fixed (global locations) or relative to the user.
  • BuildAR calls the point of reference in the real world an “anchor”, and then have “projections” attached to these (rather than “augmentations”).
  • In many ways creating AR is like creating a narrative or cinematic experience with elements of art and
  • Robs model enables creators to punch holes out to the web to embed web-content, and open web-sockets for live feeds of web-content
  • Can even set it up so that a device such as an iphone or Kinnect can act as a controller for content/objects in the AR world
  • Can apply physics engines to the objects you create (for instance on offer via Javascript).
  • OBJ is the mesh format used for 3D objects, MB2 can be used (format that comes out of Quake, can bake in animations), new format from Autodesk (Rob forgets name) can all be used.
  • Having a good object model is important, for instance can just push coordinates and orientations around which is quite efficient.
  • The model BuildAR uses means that almost anything can be plugged and played.
  • Can create custom app from Junaio
  • Designing in this 3D space is a whole new design art and thinking space.
  • Start the design with “why”.

Project ideas from attendees:

  • Margot – masters students creating a little bit of content, and potentially her creating content for students.
  • Susan – create an AR experience associated with the astronomy night brochure that showcases the activities at the event
  • Tom augmenting the experience of museum participants, having virtual objects that you can manipulate, as well as a music experience e.g. cube (Rob noted that the new audio Web API would be perfect for this)
  • Cathie is aiming to create an App for the sculpture park.
  • Matt – ASCILITE
  • Neil – communicating aboriginal stories from children (Rob suggests having the aboriginal flag as a marker that can pull up different location based information)
  • Ming Ming – semiotic analysis support
  • Rob Parker – new biodiversity planet
  • David Grover – maths view puzzle based on cubes
  • Tyrone (TAFE) – has created a couple of AR experiences
  • storytelling, blocking out stories
  • Leon – putting together some multimedia associated with fixed learning resources

BuildAR show – where they are now:

  • Currently in closed beta mode at
  • BuildAR app goes live in a week
  • Junaio uses Catchoom for the visual search – and now BuildAR is in a direct partnership with Catchoom so do not have to be victim to changes
  • Junaio doesn’t have an address bar – need to launch from Safari at the following web address: junaio://channels/?id=141781
  • IEEE International Symposium on Mixed and Augmented Reality (ISMAR) is in South Australia at end of Octoberish next year.
