A blind student will be unable to use the computer screen. Most modern applications use GUIs, so not being able to see the screen often creates accessibility barriers. As a replacement for the screen, the student will get most of their information from a "screen reader" program. A screen reader is a program that describes aloud what appears on your computer screen, speaking the text that’s in documents and windows. There is additional information on how screen readers work, and on some commonly used screen readers.
