Non-Visual Display Access (NVDA) - literally translates "Desktop Accessibility without Visual Control". The program is a completely free product for Windows, which allows the category of blind (or visually impaired) users to work with a PC without visual control (application of vision). The program displays all the information for the user by means of speech, as well as on a special Braille display.
NVDA has open source code. This means that anyone who thinks they can make useful changes to the program can participate in the development of the application. The main goal of the project is to realize the possibilities of full reading of the screen without the use of eyesight for the blind people. Programs and devices for the visually impaired cost quite a lot, while NVDA is distributed completely free of charge. NVDA works with 32/64-bit Windows. It is stated that the program can be used successfully even without installing graphics card drivers. The program already supports more than 20 languages, the list is regularly updated. It supports cursive and unspoken Braille displays. Compatibility of NVDA with the most popular speech synthesizers (that is not present, by the way, in paid software of a similar kind) is carried out.
NVDA enables blind or visually impaired individuals to use a PC with audio and Braille feedback.
