Increasingly people with visual impairments, including blindness, are using computer interfaces to get most of their information and to communicate with others. These users most often use an assistive technology (AT) device called a Screen Reader. A screen reader is a software application that attempts to identify and interpret what is being displayed on the screen (or, more accurately, sent to standard output, whether a video monitor is present or not). This interpretation is then re-presented to the user with text-to-speech, sound icons, or a Braille output device. Screen readers are a form of AT potentially useful to people who are blind, visually impaired, or have a learning disability, often in combination with other AT, such as screen magnifiers.
