A new low vision reading aid is under development that uses advanced technology and aims to improve usability and pleasurability while maintaining the learnability of existing reading aids. Existing video magnifier users, other low vision people and normally sighted matched-age controls completed a reading test using existing machines and a mock-up control panel of the redesigned unit to determ...

PURPOSE Detection and recognition of ramps and steps are important for the safe mobility of people with low vision. Our primary goal was to assess the impact of viewing conditions and environmental factors on the recognition of these targets by people with low vision. A secondary goal was to determine if results from our previous studies of normally sighted subjects, wearing acuity-reducing gog...

In this study, we asked how two types of linguistic information--characters used in segmenting words from one another, and sentence context--differ in their usefulness for people with normal and low vision. Given evidence for age-related differences in some forms of cognitive processing, we also investigated the ef...
