NonVisual Desktop Access - a free, open-source, assistive technology software that enables blind users to access personal computers

NonVisual Desktop Access (NVDA) allows blind and vision impaired people to access and interact with the Windows operating system and many third party applications.

Major highlights include:
- Support for popular applications including web browsers such as Mozilla Firefox and Google Chrome, email clients, internet chat software, music players, and office programs such as Microsoft Word and Excel
- Reporting of textual formatting where available such as font name and size, style and spelling errors
- Automatic announcement of text under the mouse and optional audible indication of the mouse position
- Support for many refreshable braille displays, including input of Braille via braille displays that have a braille keyboard
- Announcing controls and text while interacting with gestures on touch screens

NVDA has been translated by volunteers into more than 55 languages, and been used by people in more than 175 countries. NVDA is open source software, which means the code is accessible to anyone. This enables translators and developers around the world to continually contribute to its expansion and improvement.

The founders were able to work full-time on the project thanks to a series of corporate grants and individual donations. It has also won multiple awards.
