Alex R. Bowers, Egor Ananyev, Aaron J. Mandel, Robert B. Goldstein, Eli Peli
2014 Investigative Ophthalmology and Visual Science  
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.  ...
