Apple has been granted three noteworthy patents relating to the multi-touch technology found in the iPad, iPhone, and iPod touch. The first patent, entitled “Portable Electronic Device with Multi-Touch Input,” describes a method of input that includes “displaying an object on a display surface of a portable electronic device; detecting multi-touch input associated with the object; determining, based on the multi-touch input, an operation to be performed on the object; and performing the operation on the object,” and also mentions gesture recognition and Web page rendering in a multi-touch environment.

The second patent, “Ellipse fitting for multi-touch surfaces,” covers the tracking of multiple fingers and palm contacts as approach, touch and move across a proximity-sensing, multi-touch surface, and the integration of different types of manual input including typing, direct manipulation, and handwriting. The final patent, “Simultaneous Sensing Arrangement,” discusses multi-touch touch-sensor devices and the methods they use to detect and understand touch placement and movement. [via Patently Apple]
