"A new 30-page patent filing by Wayne Westerman and John Elias, co-founders of the Fingerworks firm acquired by Apple during the development of the original iPhone, details a handful of these newly proposed inputs under the title "Multi-Touch Data Fusion." 


The patent describes new ways to interact such as Voice, Finger identification, Gaze Vector (uses your camera to see where you are looking), Biometrics, and Facial Expression.  Take a look below for the Patent Images as they pretty much describe themselves.

According to an update I recieved,  The voice and facial recognition aspects of Apple’s patent application,  filed in June of 2007,  may violate these aspects of Apple’s patent found at: http://www.UltimateMobileDevice.com.
