NVDA (non-visual digital access dais) is an easy to use computer program that allows full vision impaired individuals to operate computers easily. NVDA stands for: Non Visual Computer Access. It is designed to provide the user with hand - eye coordination through speech. You may want to call attention to special areas on the computer screen. To do this, just point to them with the pointers on your keyboard or mouse, and press the appropriate keys.
NVDA is used in many places, including educational institutions, rehabilitation centers, corporate settings, offices and homes. This program is very flexible and adaptable to all sorts of environments. In addition, people with low vision can also take advantage of non-visual desktop access using computer software called Nvu viewer. Nvu viewer is like an accessible web browser, which presents web pages just as they would appear to a sighted person. You view the web page as a web page layout with no special computer software involved. You may also want to use this software to make presentations, view photos and share documents.
One thing that is different about NVDA is that it gives disabled users a way to browse the Internet and visit websites that are not accessible to everyone, like books, newspapers and magazines, etc. However, NVDA technology does more than just give disabled people a way to gain access to websites and computer programs. It also provides a way for people who are visually impaired to work in their usual professions. For example, a service operator in a grocery store or a customer service agent in a bank uses NVDA to perform a specific task, without ever seeing another individual handling the same task. A computer programmer can type and view files in their usual work environment using NVDA without having to worry about whether their hands are perfectly in place to type accurately or view a file precisely. All these capabilities have made NVDA technology very useful for many people with various disabilities.
