Braille system has _____ dot patterns or characters.

Amita is studying in class $8$ of Government Model High School. Recently in her school, an NGO team helping visually- challenged people were invited. The NGO team came and took a session on the difficulty faced by visually-challenged people. They motivated the students to try a small experiment. The students were asked to go to sleep with a piece of cloth tied to their eyes. They had to stay blindfolded for a day so that they could experience the difficulties faced by visually-challenged people. In order to experiment this, Amita went to bed with a piece of cloth tied to her eyes. When she woke up the next morning, she was unable to see anything. Her mother came and helped her with the morning routines. Going to the bathroom, brushing her teeth, and having a bath were a real challenge. Amita felt completely useless and helpless because it took her more than one hour to complete these activities. Amita's friend Jenice came and helped her in getting ready for school. Walking to school with a stick in hand needed some learning. Amita was constantly afraid of falling and hurting herself. By the time it was evening, Amita was relieved that the day was over. Her experience helped her understand the difficulties of visually-challenged people. She thanked God for giving her the gift of sight. What is Braille?
