Visually Impaired Access to computers

Some people may be surprised to find out that the blind and visually impaired are about as likely to be on the internet as a sighted person. It can seem like a daunting task to learn to use a computer system, but the fact is, there are plenty of easy ways for the visually impaired to get online.

A common method for computer access for the blind and visually impaired is a screen reader. There are many screen reader programs available, the most common is the JAWS screen reader. A screen reader takes the output from Microsoft Windows and converts it to speech. The screen reader will tell you that you are currently in the Internet Explorer browser, and it will read to you the contents of the web pages. With time, and practice, a blind or visually impaired user can become very proficient at using a computer system. Screen Readers offer a great degree of flexibility, you have full control over your computer. However, the screen readers are often difficult and time consuming to learn. Each program generally has different button combinations to access different menus and systems. These button combinations must be memorized. There are, literally, hundreds of possible key combinations which provide a great deal of control, but can be very daunting to learn.

Another method for computer access is to use an assistive technology device that simplifies the Windows operating system down to a few common workflows. There are a few devices on the market which do this. The SpeakEasy Media System is one such device. It is a system that comes with hardware and a preconfigured e-mail address. The system provides simple, menu driven access to e-mail, typed documents, news articles, podcast audio shows, encyclopedia entries, dictionary entries, and more. The SpeakEasy does not provide as much control over the system as a screen reader, however it is an excellent option for easy access to the most common functions that the blind and visually impaired will use.

Lastly, there are also machines specifically designed for reading typed documents. These reading machines will take a typed document and convert it into speech. They do not provide any access to the internet, nor do they support any function beyond simply reading a document. However, they are very simple to operate. There are a number of standalone reading machines on the market, one such machine is the Simon reading machine.

The options discussed provide a good cross section of the available access methods to computers for the blind and visually impaired. Screen Readers provide the most functionality, but are also the most difficult to use. Reading machines are simple to use, but lack most functionality. The media system provides most functionality of a screen reader, and also provides an ease of use experience similar to a reading machine.
