Computers for people with visual disabilities
Someone with a visual disability could find the information on the screen or difficult to read. That is the main obstacle. In addition, the use of the mouse is often a problem because he has no overview or less across the screen.
Fortunately there are tools that provide a solution to these problems and the standard applications of a computer useful for people with visual disabilities.
A custom computer for a visually impaired
One would have impaired vision remaining best use. He therefore uses mostly a magnification program (depending on the visual deviation possibly combined with a larger monitor) the screen image is enlarged. This does mean a loss of overview. Such programs can also enhance the color change to enhance contrast.
While increasing for many the ideal adaptation is impaired when typing text (eg a word processor), meaning speech output in many cases a better alternative to reading documents (eg a web page). Therefore, most visually enlarge a program with a speech program, which enlarged and said display simultaneously possible.

A blind typically uses a Braille display or speech output or a combination of both. A braille display , the text of the computer screen in Braille display. Voice playback software reads the information with a computer voice. Both tools can separately or simultaneously.
Because there is only text can be displayed, there is additional software required: a screen reader (or screen reader in Dutch). This program ensures that the Windows graphical environment is described in text using Braille or speech so they can be used. Finally, there is an alternative to the mouse control is needed.
