Representation of Graphical Images for the Visually Impaired

: The visually impaired have been included in computer industry from the time it began to be popular among wider user population. Various text-to-speech synthesizers have been developed and used as a viable aiding technology that has enabled the visually impaired to use computers, to read various text materials, and to get information quicker and easier. The same technology has been used to enable the visually impaired to work as professional programmers and other computer experts. The inclusion of graphical user interfaces into broad computer usage has made using computers increasingly difficult for the visually impaired. Existing aiding technology has not been able to interpret graphical elements and overall context of the screen real estate. As a response, different solutions for representation of graphical images have emerged. In this paper, an overview of different technology used to represent graphical images is given, along with the future research directions.
