Computers and Software

Technology has changed the way we undertake many tasks, from accessing information to driving a car.
Even if it hasn’t been part of your education or life experience so far, it is possible to learn the skills necessary to make use of computer technology and software. Talk to one of the many low vision service providers about computer training programs and typing courses. Local Computer Pals clubs for seniors, which offer a fun and supportive environment, may also be suitable for learning computer skills. Technical Aid to the Disabled (TAD) can help to provide affordable computer packages for people with a disability.
Another excellent resource is Media Access Australia (MAA). MAA is a not-for-profit organisation devoted to increasing access to media for people with disabilities. Their website contains information on assistive technology.
Maximising vision using computer technology
There are many ways you can maximise remaining vision by using technology, including choosing a large screen to increase the viewing area and increasing the size of items displayed on the screen.
To make type easier to read, choose simple fonts without decorative curves, such as Arial or Calibri, and type in upper and lower case instead of all capitals. Add extra space between words and lines of text.
The following modifications will help you get the most from your computer:
- A large monitor to increase your viewing area
- A large print keyboard or large font keyboard stickers applied to the keys
- Software that increases the cursor size
- If the mouse or cursor is difficult to use, it may be easier to learn to touch type and use keyboard commands
- Enlarge the toolbar display
- Change the colour contrast
Computer technology for people with low vision
Electronic note takers
An electronic note taker is basically an adapted personal data service. Users can do the same tasks that a typical personal data device allows including: taking notes, reading email, diary functions, calculator, playing music, or digital books and data transfer to or from computers. Because the electronic note takers are adapted for persons who are blind or vision impaired, they have built in speech output.
Tablets and small personal computers
Netbooks, ultrabooks, and tablet personal computers are essentially just small computers. They are highly portable which means that those with low vision can readily access low vision technology when out and about.
Software options for people with low vision
Screen magnification software
Screen magnification software increases the size of the image displayed on the screen. This means only a portion of the original screen image can be seen at one time. The mouse or keyboard can then be used to move the magnified window to view other parts of the original screen image.
Screen reading software
Screen reading software is also available to translate text into speech and is designed for people with very little usable vision. They may also be built in to some websites such as this one – by pressing the ‘Listen’ button at the top of the screen, the text will be read aloud.
Screen magnifier and reader
At times, a program with a screen magnifier AND speech reader may help. For example, Type Echo - hearing text as it is typed can be useful for new or slow typists. Listening to long documents or web pages may be less tiring than reading with a screen magnifier.
Additionally, starting with both magnification and a reader may simplify the transition to speech only if vision deteriorates further.

Free software options
There are a number of free software options to choose from, provided by suppliers that include Microsoft, Apple and Linux.
Microsoft Windows has a built-in narrator, and has third party software support, which allows for greater access.

Whether you use Windows or Mac, you access the Internet through a web browser. There are several web browsers available, the most popular being Internet Explorer, Mozilla Firefox and Chrome.
