Connected (or Refreshable) Braille Display
A refreshable Braille display is a piece of computer hardware that has a series of refreshable Braille cells on its surface. Each Braille dot in these cells is represented by a tiny pin that can be raised or lowered. This allows individuals who are blind to read information in Braille by running their fingers over the refreshable braille cells and then advancing the display to show the next set of characters. Connected Braille displays work in conjunction with screen reading technology to convey digital information to the user. Whatever information the screen reader is able to provide is displayed in Braille on the device.
