Im building a multi touch screen for my mphys project. My biggest problem is the software… How do I track my blobs and how do I calibrate the points? I’, trying to use the patch CamShiftTracker am I going the right way?
Thank you
or maybe here
Hi Sarah!
I have also built a multitouch table some weeks ago. For the tracking of blobs I used TBeta (nuigroup). It does the whole tracking stuff and is really easy to handle! In vvvv I use the UDP / TUIODecoder nodes to process the blob data.
If you come to the point of hit testing blobs against objects, i can recommend robi_h’s plugin HitTester2D
