Assistive technology designed to convert printed text into audible speech or braille output empowers individuals with visual impairments to access written materials independently. These devices range from simple handheld scanners to sophisticated computer programs capable of processing complex documents and books. For example, a portable device might scan a restaurant menu and vocalize the options, while more advanced software can navigate digital libraries and render academic texts accessible.
This technology plays a vital role in promoting literacy, education, and employment opportunities for people with visual impairments. By bridging the gap between print and accessibility, these tools foster independence and inclusion. Historically, access to written material for the blind relied heavily on braille and human readers. The advent of these technologies marked a significant advancement, opening doors to a wider range of information and experiences.
