Braille is a system of touch reading and writing for visually impaired people, in which raised dots represent the letters of the alphabet, numbers, punctuation marks, special symbols and so on. It is named after its creator, Louis Braille, a Frenchman who lost his sight in his childhood and later developed a code for the French alphabet. These characters have rectangular blocks called cells which have tiny bumps called raised dots. The number and arrangement of these dots distinguish one character from another. ----------------------- What’s Braille Academy? Braille Academy is developed to help those who are curious about and interested in learning the Braille system. The two key teaching concepts are gradual introduction and focused repetition. The learning material is categorized into chapters and then levels to ensure efficient learning and training. If you are not particularly interested in Braille but in training and improving your memory in general, Braille Academy is also a useful tool. ----------------------- Levels and challenges? In short, a level focuses on introducing new characters with a small amount of repetition while a challenge trains what you’ve learnt already. In a level, you can click the INFO BUTTON (on the left) to read some TIPS and the hint button (on the right) to see the correct answer. The hints are infinite and always free. In a challenge, you can’t use the hint button anymore and you must make less than 3 mistakes to pass it. In conclusion, I wish you a lot of success and a lot of fun in learning Braille!
