The Braille system is a method that is widely used by blind people to read and write. Braille was devised in 1821 by Louis Braille, a Frenchman. Each Braille character or cell is made up of six dot positions, arranged in a rectangle containing two columns of three dots each. A dot may be raised at any of the six positions to form sixty-four (26) permutations, including the arrangement in which no dots are raised. For reference purposes, a particular permutation may be described by naming the positions where dots are raised, the positions being universally numbered 1 to 3, from top to bottom, on the left, and 4 to 6, from top to bottom, on the right. For example, dots 1-3-4 would describe a cell with three dots raised, at the top and bottom in the left column and on top of the right column, i.e., the letter m. The lines of horizontal Braille text are separated by a space, much like visible printed text, so that the dots of one line can be differentiated from the Braille text above and below. Punctuation is represented by its own unique set of characters.
a braille printer produces braille printouts of computer files. It works in conjunction software that translates text to braille.It converts a computer file into a BRAILLE DOCUMENT.
it works by dots u can feel them u have to memorize the dots to read it but it works by having dots u feel them
work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........
these are raised bumps on paper, that are coded, blind people have to learn how to touch them and interpret them into words, this is quite a feat and takes months of practice.
Work done by the system is considered as PositiveWork done on the system is considered as Negative
