so i just revamped a gesture recognition patch for quartz composer. this is doing a point to point evaluation with tolerance settings on a custom gesture.
feel free to download the source or watch the proof of concept video. to record a gesture you you single touch with a second finger double hit (click) record your gesture then use a 3 point/finger touch down to enter runtime evaluation mode. once your in eval mode you can do your gesture at anytime. this is evaluating x/y pos as well as time. feel free to change tolerance setting as needed. this is a proof of concept that will work as handwriting recognition or what ever custom gesture you need. right now im doing a star gesture but feel to make your own.
so the requisites for this is the TUIO plugin built to 64bit for snow leopard, although the algorithm is backwards compatible. it also uses kineme structure maker which is essential in addition im using some kinme gl tools for some touch triangulation but it is used only for a cursor and not really needed. check out the tuio site for a patch of mine they are showcasing. this gives me warm fuzzies.
go to http://kinme.net for requisite plugins as well as tuio.org for the tuio plugin.
here is the direct link to the proof of concept video.
as well as another experiment video of some tuio m_accel and inertia gesturing
im attaching the custom gesture source but feel free to browse my site. its only a couple weeks old so im still filling it with exapmles etc..
