What is a Braille Display?
Published: Jun 19, 2007
An electronic Braille display is a tactile device that enables the user to read the contents of the computer screen by touch in Braille. It is placed under a conventional computer keyboard or laptop keyboard. They are also referred to as paperless, soft or refreshable Braille displays and vary in size from 20-80 Braille cells. Large Braille displays with 70-80 cells are perfect for desktop PCs and fit under a standard desktop keyboard. Braille displays for laptop and notebook PCs have 40 or less cells.
Use of Braille display
Braille can provide layout information more efficiently and users find using a Braille display to be more accurate. For instance, a spelling mistake is more obvious on a Braille display than hearing a mispronunciation amongst a lot of speech. The general theory is that speech is for speed and Braille is for accuracy. Braille is a natural way of working and an essential communication medium for deaf-blind people.
Price of Braille displays
Braille displays are expensive and their price varies depending on the number of Braille cells and features available. They start at $3000 USD and cost up to $18,000 USD with the most popular displays costing around $4000 USD to $8000 USD.
