Layering of eye technology for better performance

Computer scientist sees new possibilities for ocular biometrics (Phys.org)

[Oleg Komogortsev and a team at Texas State University] are developing a three-layered, multi-biometric approach that tracks the movement of the eye globe and its muscles, and monitors how and where a person's brain focuses visual attention, in addition to scanning patterns in the iris. The iris is the colored part of the eye.
