Rumours that the Samsung Galaxy S4 will support eye and head tracking have cropped up on numerous occasions, but this is our first ounce of hard evidence.
The screenshots below were supplied by an unnamed source to SamMobile and clearly show options for eye and head tracking. The functions will be used in certain apps such as Chrome and Google’s Gmail App where the front camera will track the position of your eyes and scroll down the screen as your reach the bottom. Head tracking will work in apps such as the media player, and will automatically pause video when you turn your head away!
Cool stuff! But could these screenshots be fakes just as the @eleaks renders turned out to be? Only time will tell!Source ]
