Touchy - Highly configurable jQuery plugin. Exposes event data (velocity, etc) for longpress, drag, pinch, rotate, swipe. Example use cases: prevent conflict between drag and swipe; get pinch abstracted across Android and iOS; create a single finger rotation.
jQuery UI Interactions - Rewrite of the existing jQuery UI interactions, now with mouse, touche and pointer (aka MSPointer) support. Work in progress, but draggable already works great for all three event APIs.
