Open Input Framework Grail Library

Registered 2010-08-12 by Duncan McGreggor

Gesture Recognition And Instantiation Library

Grail consists of an interface and tools for handling gesture recognition and gesture instantiation.

When a multitouch gesture is performed on a device, the recognizer emits one or several possible gestures. Once the context of the gesture is known, i.e., in what window the touches land and what gestures the clients of that window listen to, the instantiator delivers the matching set of gestures.

The library handles tentative getures, i.e., buffering of events for several alternative gestures until a match is confirmed.
