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, ranging from portable handheld scanners to sophisticated desktop systems, employ optical character recognition (OCR) to interpret printed characters and translate them into alternative formats. A common example involves scanning a printed page, which the device then processes and vocalizes aloud, enabling the user to “hear” the text.
Access to information and literacy is a fundamental human right, and these technologies play a vital role in ensuring equal opportunities for individuals with visual impairments. By bridging the gap between printed text and accessible formats, such devices foster independence, promote educational attainment, and enhance overall quality of life. The development of these technologies has a rich history, evolving from bulky and expensive machines to increasingly portable, affordable, and feature-rich solutions.
