- Traffic gap detection for pedestrians with low visionDuane R Geruschat
Salus University, Philadelphia, Pennsylvania, USA
Optom Vis Sci 88:208-16. 2011..The purpose of this study was to evaluate the effect of two types of vision loss (central or peripheral) on the ability to detect gaps in traffic...

The Johns Hopkins University School of Medicine, Wilmer Eye Institute, Baltimore, MD 21205, USA
Vision Res 42:2635-44. 2002..Similar to what was found with visually normal subjects, CFL subjects appear to use the expected features and general location of the target to guide their fixations, the guided-search strategy...
