Samsung's New Smartphone Will Track Eyes to Scroll Pages - NYTimes.com

Multi-taskers need not apply

"Samsung’s next big smartphone, to be introduced this month, will have a strong focus on software. A person who has tried the phone, called the Galaxy S IV, described one feature as particularly new and exciting: Eye scrolling.
The phone will track a user’s eyes to determine where to scroll, said a Samsung employee who spoke on condition of anonymity because he was not authorized to speak to the news media. For example, when users read articles and their eyes reach the bottom of the page, the software will automatically scroll down to reveal the next paragraphs of text."
