Assistive Devices for Visually Impaired
Keywords:
visual impairment, total blindness, legal blindness, auxiliary devicesAbstract
The aim of this paper is to describe devices used as support for visually impaired people. In order to do this, we describe important data on the definition of disability, information related to visual disability in the world and in Mexico, as well as its definition and characteristics described by the World Health Organization. Subsequently, a classification of auxiliary devices for visual impairment is depicted: auxiliary devices for displacement, for recognition and specialized.
