Eye-tracking tech in the Samsung Galaxy S4? Say what?
Navigating the phone with your eyes is one of the Samsung Galaxy S4's rumored features. !!!
Eye-tracking uses the camera to lock onto the motion of a user's peepers, following wherever they move. With it, the phone can perceive where the user is looking, and can respond to a set of behaviors, let's say a very intentional movement to scroll a Web page up and down, or a long, purposeful blink to click.
If your eyes have reached the bottom of a page, eye-tracking software could automatically scroll you down the following paragraphs of text.
This type of technology -- which had been researched for desktop computing long before it was conceived of for the smaller smartphone screen -- has been demoed for a variety of actions: zooming in or out, pausing a video by looking away from a screen, and playing games.
