Texas State University researchers have developed ocular biometric software that can be used in the medical field to identify eye movements associated with concussions and traumatic brain injury patients.
The software also can be applied to human-computer interaction research because it can calibrate where a user's eyes are looking on a computer screen. The researchers tested the software using a game. During the game, users must first allow the software to record and calculate their eye movements as they watch a computer screen. The software recognizes where the user's line of sight is directed and signals an input command so the game can be played using only the eyes. The researchers say they also created hardware platforms for eye-data collection and analysis at lower costs than commercially available systems.
Although eye-tracking technology can cost thousands of dollars, the researchers created iris-recognition devices from $20 Webcams, notes Texas State professor Oleg Komogortsev.
