Braille

There is an entry for Louis Braille in Wikipedia, complete with a couple of photos of busts of him.

Braille is a writing system that is used by blind and visually impaired. Braille was developed by Louis Braille who went blind as a child and developed the system at age 15. The braille system is raised bumps that are found on paper and each represent something different. The braille alphabet can be found on many websites.

Braille, the system of raised dots which is used by blind or visually impaired people to read, was developed by Louise Braille in 1824.

No, you read it left to right. The fingers feel in the same pattern as the eyes read a line of text on a page. They go from the top left to the top right, move a line down and continue the pattern.

When writing braille by hand using a slate (a special stencil for braille), it is written from the back side of the page, from right to left so that it reads correctly from the front side of the page.

Braille is not a language. It is a group of writing systems that are used by people who are blind. If you read braille text aloud, you are reading whatever language the braille was written in. It's not a spoken language, it's a written language so you don't actually speak it.

Louis was blind at the age of 3 not very old and he died at the age of 43 not old.

They didn't. That is why braille is such a big thing. They could read all by themselves instead of waiting until someone else could read for them.

When Louis Braille was 3, he was playing with one of his father's tools called a Stitching awl. It was used to sew leather.http://wiki.answers.com/wiki/File:Sewing_awl.jpg

It depends where they are. There are six possible dot positions, two columns of three dots each.

So 3 dots could be D, F, H, J, L, M, O, S or U.
