Gaze Pattern Lock for Elders and Disabled

摘要

The experiences with the eye tracker have highlighted new issues for further investigation and developing solution. On our ongoing research we are trying to combine two different biometric user authentication methods relying on gaze pattern recognition while face features matching. This article presents methodology of using the mobile eye tracking system for user authentication. The project is mostly aimed in to the elderly and disabled computer users and includes supporting authentication procedure that gives access to the classified data with gaze pattern lock. The experiment is to use the eye movement tracking system to collect the data while the eyes of the person who is being identified follow the point on the computer screen. Whole experiment relays on the Yarbus's experiment who showed that the viewers' eye movements differ according to the viewer's task. This article also presents a results of gaze pattern matching as the authentication procedure.
