Is there a high level library that handles complex gestures l ike detecting triangles / loops / circles? Is it even possible to build such a library with what Apple already has?
Thanks,
Teja

You can use a “Dollar Recognizer“… its pretty accurate and very easy to use from a single training template. There is even an effort started for an iPhone implementation, although its not been released yet. An implementation is being used by AlphaCount.
