Braille is a system of raised dots that can be read with the fingers by people who are blind or who have low vision. The raised dots represent the letters of the alphabet.
Not all blind people would know Braille, some prefer to use computer software while others never had the opportunity to learn. Therefore, always ask people about their preferred way of communication. Should you need to print information in Braille, consult with DPOs or educational institutions, or disability specific humanitarian organisations.
