Assessment of newly designed fonts for visual accessibility.

PLoS ONE
PurposeThe visual accessibility of fonts refers to the range of print sizes and efficiency with which readers can access text. One goal of font design may be to maximize accessibility for a wide range of users including those with low vision.

VI-OCR: “Visually Impaired” optical character recognition pipeline for text accessibility assessment

Scientific Reports
Low vision adversely impacts daily activities, particularly reading. However, quantifying text accessibility for different levels of low vision is challenging, leading to product designs that often overlook the vision status of low vision readers.

Intact high-level visual functions in congenital rod-monochromacy

Frontiers in Neuroscience
High-level visual functions such as reading and face recognition rely on global processes, which are often insensitive to high spatial frequencies. However, it is unknown whether a sharp cone signal is necessary for the development of these skills or ...
