Samsung Unpacked teaser video and eye scrolling on the Galaxy S4

Samsung has released a teaser video for their coming Unpacked event March 14. It doesn't say much, just "A new Galaxy" and the number 4. So it's kinda obvious that we will see the new Galaxy S IV android smartphone.

A new rumor says that the S4 will have a new eye tracking feature that makes it possible to scroll with your eyes. It sounds like science fiction, but is probably true. Samsung already have an eye tracking feature called smart stay on the Galaxy S3, that makes the screen stay on as long as you look at it. And it works really great. Not in complete darkness though. But that's understandable. I think this new eye scrolling feature could be the latest version of the Smart Stay feature.
