thxs for sharing this awesome project . It ‘s very inspiring in so many ways .
Answering specific needs (musical use )
Lowering the floor, (reducing the hardware needs) ,
Opening a wide range of possibilities ( providing tools for creation )
Here goes a few comments & questions .
1/ MT Musical Instruments have been a recurrent topic in this forum, some music apps have been released around some using Flash , Processing or Max ,
but your object approach (musical object editor ) is quite unique .
There is also this ongoing musical GSOC project developed under NUIGroup supervision .
Your insights will be definitly welcome .
2/the form factor :
a / As outlined by Martin ,
the simple paper based reference frame approach of your system,
is simply stunning .
It fits perfectly for a musical use, since the “zones” indicates the right place to interact, the audio gives the feedback to the user .
b/ It also gives a great example of new ways to interact with a multitouch surface (no display (lcd, monitors, or video projector)) .
Even more affordable since the vp is the most expensive part
c/ as described in your paper , your LLP method is using a mirror before reaching the line lens.
Can you post some pics of this setup ? ( transforming ordinary surfaces into MT controllers)
3/ Surface Tracker software
do your tracker implement the built-in tracking from the Optitrack camera ? Is the blob tracking is still done inside the cam ?
Your “tool for creating polygons for drawing arbitrary “ interactive shape is also a great contribution
5 / Do you plan to share the audio apps showcased in the vid ?
Do you plan to update the documentation ? to provide more examples ? or an example suite (as the Trackmate project did )?
How do you envision the future of this awesome project ?
