RUMOR: The Samsung Galaxy S IV is set to be unveiled on March 14th, and is rumored to offer a feature no other cell phone currently does -- the ability to let you scroll through its screen using just your eyes!

A Samsung employee told the New York Times that the phone will track a user's eyes in order to determine when to scroll.

In February, Samsung filed for a trademark for the phrase, "Samsung Eye Scroll," in the U.S., describing the software as, "Computer application software having a feature of sensing eye movements and scrolling through mobile devices..."  Some other rumors surrounding the phone say it will have a five-inch screen and a 13MP camera.
