Cool links!
For AR I've been using the Qualcomm AR kit, which is free and works great with Playmaker. It's very easy to setup and comes with the basic behaviors you'd need to get it working. Then you can just use Playmaker to control the scene...
Have you tried used uart or Qualcomm? What features would you like exposed in Playmaker?
I'm a huge AR fan, so definitely want to support it in Playmaker...
Also a huge Kinect fan. Just got Kinect for windows to play with
. Again, would love to support this in Playmaker, but need to play with it some to figure out the most useful way to integrate it.
Any specific action ideas for both areas would be most welcome!
