The Wearable Low Vision Aid (WLVA) is a portable system that uses machine vision to track potential walking hazards for the visually impaired. A scanning fiber display couples a laser diode to a vibrating optical fiber that projects a virtual image onto the retina to display warning icons that the visually impaired can recognize. Initial low-vision subject testing has given promising results for this low-cost assistive device.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
