Eye-tracking cameras offer a new way to control your computer. A camera over the screen is a standard feature for laptops. But only Lenovo’s new model has a pair of cameras below its display to track the movements of a user’s eyes.

The laptop can notice when its user has read to near the bottom of a page and can automatically scroll down to reveal more text.
