A visually impaired computer is designed for people with low vision and can be used to a limited extent by blind people. It magnifies text and images on the screen or reads the screen contents. Other features include motion tracking aids, speech recognition software, and area-based navigation. However, it may not allow for completely unlimited use of everything a computer has to offer.
A visually impaired computer is a computer designed for (or which includes programs to allow) easy use by people with low vision. A visually impaired computer can, in some cases, be used even to a limited extent by completely blind people. Computers for the visually impaired generally focus on magnifying text and images on the screen or reading the screen contents for the computer user. Both of these methods can, at a minimum, allow for basic computer use, such as reading and composing documents; operation of some media players; and even, in many cases, surfing the Internet. Some even offer motion tracking aids so that visually impaired people can track the cursor as it moves across the screen.
The most common approach used to make a visually impaired computer is to increase the size of the text and images on the computer screen. Many computer systems include applications that will magnify all normal-sized objects on your computer screen to make them easier to see. This type of visually impaired computer application tends to provide the most help in reading text. Pictures and other objects can look cluttered and distorted if you zoom in too much, but you can usually zoom in on text while maintaining formatting and clarity.
Another type of vision impaired computer works by reading the contents of the computer screen to the computer user. In many cases, the computer user interacts with the computer by giving spoken instructions. As such, this type of vision-impaired computer system tends to rely on speech recognition software.
There are many other types of applications for low vision computers that can greatly help computer users who have low vision. Some programs magnify the cursor or leave a visual trail behind it to make it easier to track on the screen, for example. Others increase the contrast of the screen so that foreground elements, such as text, stand out more against the background. Still others provide area-based navigation so that you can selectively zoom in on a certain area of the screen without radically altering the entire layout by zooming everything.
While a vision-impaired computer system can provide a great deal of assistance, it is generally not enough to allow for completely unlimited use of everything a computer has to offer. Many programming interfaces, websites, and games are nearly or completely unusable if the user is unable to visually track a large amount of information on the screen. Improvements in computer storytelling technology and other forms of visual assistance may eventually increase the functionality such systems can offer.
