The eyes have it
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 prototype laptop can be controlled with eye motions, reducing the need to use the mouse and making it faster to navigate through information such as maps or menus.
Manu Kumar, who worked on eye-tracking techniques at Stanford University and now runs the seed-stage venture capital fund K9 Ventures, says that such technology, if well designed, has a lot to offer most computer users. "To computers, humans are really just a big finger; everything is based around that mode of input," he says. "Using eye tracking increases the bandwidth between the human and the computer."
