Assistive technology enabling access to printed and digital text for individuals with visual impairments encompasses a range of devices. These tools convert textual information into non-visual formats, such as synthesized speech or braille. Examples include screen readers that vocalize on-screen text for computer use, portable scanners that can read printed documents aloud, and refreshable braille displays that provide tactile output. These technologies often integrate optical character recognition (OCR) to interpret printed characters and translate them into accessible forms.
Such accessibility solutions significantly enhance educational and employment opportunities, promote independent living, and foster social inclusion for people with visual impairments. Historically, access to information was severely limited, relying heavily on braille materials and human readers. The development of these technologies represents a substantial advancement, opening up a world of literature, news, and information that was previously inaccessible. This greater access promotes literacy, expands knowledge, and empowers individuals to participate more fully in society.
