A Laptop that Knows Where You're Looking

There is a new laptop by Lenovo which it can sense where the user is looking. It uses the users eye motion to sense where they are looking. This is helpful because where you're reading a text at the bottom of the screen and you don't feel like scrolling down with your mouse the laptop will scroll down by itself with just your eye motions. Also when you aren't looking at the computer it will dim down to save some power. Tobii, a swedish company provided the eye motion software and prototype. The inventor want to make the navigation on the computer more natural. So far only 20 have been made. The computer works by having two cameras at the bottom of the screen one to track the pupil and the other to provide light to make a glint in the eye to make it easier. It is 0.5 degrees accurate. This is a prototype to also test out how ready eye tracking is ready for the market.
