Tuio touch data is now available as UnityEngine.Touch objects via the TuioInput object. TuioInput has an identical signature to the native Input object, so existing iPhone and Android touch applications and plugins can be quickly and easily converted to run on Tuio.

Also included in the project is MindstormGestures providing a framework for interacting with objects using touch. 4 example projects are provided including a photo browser.
