Some of the traditional “IBMesque” features are expanded in the Y series, including an optical login:
Though it integrates a Webcam above the display like many other contemporary portables, it has one cool feature which uses the camera in a novel way. Forget about biometric fingerprint scanning. The Lenovo Y300 allows one to login just by looking into the Webcam. By taking the distance between the eyes and nose, as well as several high points in one's facial features, the system can recognize authorized users and automatically logs in
Quite fascinating, and definitely a novel idea. Potential releases in other countries aren't mentioned in the articles.
