One of the most amazing developments I've seen in education over the past ten years is the way that technology has created a revolution in possibilities for disabled learners.

Text-to-Speech software helps students with visual impairments by allowing them to listen to the text that appears on a computer screen. This is a huge improvement over Braille because once the programme is installed on the computer, it can read anything on the screen, no matter what format it is in - pdf or website - with no waiting for a Braille translation. This enables students to participate in online activities, use email and text, and have immediate access to course materials.

Visual aids include screen magnification software that enlarges portions of the screen where the reader directs the mouse, screen reader software that translates screen text to Braille, text-to-speech programmes, or audio texts. All of these can be used by students of many different kinds of visual disabilities.
Audio aids include alerting devices that use flashing lights or icons on the computer screen rather than sounds to signal users, close-captioning for videos, TDD also known as Telecommunication for the Deaf, and phones with Voice-Carry-Over technologies that allow students with hearing difficulties to communicate over the phone with their own voice.
For students with physical disabilities, several technologies are available to assist them in completing their schoolwork, including audio books for students who cannot physically handle books, keyboard adapters such as keyguards to prevent mistyping from tremors or loss of control, or voice recognition software for students who cannot type.
Online education also helps disabled students because some of them study better in an environment with limited distractions and more accessibility than might be available in many classrooms or on very large campuses.
