ABSTRACT
Braille is a very useful tangible code for reading, writing, and communication for blind and VLV individuals. However, it is also a dying skill, with the majority of blind people failing to use the code. The problem of Braille literacy will be discussed later in this chapter. Braille was invented more than a century ago by Louis Braille, who could not foresee the advent of new technology. This new technology has sometimes aided the readers of Braille, but has also served to discourage other blind individuals from learning to use the code. It is important to point out that while it could have been possible to produce raised-line letters for use by blind people, the letters would need to be larger than Braille characters to make them “tangible” and easy to identify (Loomis, 1979).
