Hi nightofgrim reacTIVision is a no go for construct2 as it captures motion and turns it into TUIO data You need a TUIO client
Looking at this TUIO client as a possible plugin adaptation: https://github.com/fajran/tuiojs/ could be nice to have true multitouch in the browser?
The speed concerns me though!!!
Then again you could go native with Cinder (C++), or if you are just getting starting and the code stuff is kind of scary (like me!), try open frameworks http://www.openframeworks.ccandybramwell2012-07-14 10:46:11
