Creating 3DUIs that use Kinect, Wiimotes etc. can be tricky with getting the hardware and software to work, and then coding the actual interaction.
I created the following survey to map problems in 3D user interface development:
If you have tried developing your own 3DUI applications, please answer the survey. The results will help to make things easier for 3DUI hobbyists. I’ll publish the results in a scientific publication next year.
Keep on prototyping,
P.S. Currently we are working hard with getting first major release of RUIS out: Kinect support is mostly added, and we just acquired PS3 to add support for Move.me (and the Move controllers). The release should be out in August or September.
