Stu Dennison writes "Ars Technica has a post up on a new service called EyePassword. EyePassword is a system that attempts to mitigate the issues of shoulder-surfing via a novel approach to user input: no hands required. With EyePassword, a user enters their password using an on-screen keyboard that detects the orientation of their pupils. From the article: 'The gaze-tracking system functions by shining an invisible infrared beam on a user's face. The beam produces a tiny reflection in the eyes that stays put, no matter where a person looks (provided they do not move their head too much). By tracking the stable position of this reflection and the relative position of a person's pupils, the system is able to calculate which keys or buttons a user wishes to input, and interpret the information accordingly ... more than 80 percent of those tested preferred the EyePassword method. Additionally, when testing EyePassword input using an input method where users visually "dwell" on the characters they wish to input, error rates were comparable to keyboarding.'"
