Sao Mai Computer Center is equipped with seven Braille Displays.
A Braille Display is a technology that replaces the screen. It allows the blind to read the screen output in another way.
The computer screen is organized into lines and columns. The Display can "translate" in Braille 40 characters at a time of the selected line (that can be touched-read on a bar). With navigation buttons (arrow keys) you can read the rest of the line or scroll up and down.
The Braille Display in the picture has keys by which you can write in Braille code. It is equipped with Function keys so that it may be used instead of the keyboard. It can be also used in conjunction with a screen reader software.
