To date, few studies have investigated the eye movement patterns of individuals with glaucoma while they undertake everyday tasks in real-world settings. ...
Furthermore, we discuss current developments in eye-tracking technology and the potential for combining eye-tracking with virtual reality and advanced analytical approaches. ...

Using a driving simulator, we examined the effects of homonymous hemianopia (HH) on head scanning behaviors at intersections and evaluated the role of inadequate head scanning in detection failures. ...
However, head scan magnitudes of HH drivers were smaller than those of the NV group (P < 0.001). ...
The system tracked the head with 18 relative accuracy and a range of 6708, sufficient to capture large scanning movements at intersections. ...
