Coding by letter shifting and substitution involves manipulating the arrangement of letters in a word to encode a message. The process involves shifting or combining letters to represent the corresponding digits or symbols in a code. This technique allows individuals with limited or no reading ability to communicate by creating visual patterns or sequences that represent spoken words.
For instance, if we have the word "HELLO", we can rearrange the letters to form the code "12345". By manipulating these letters in a specific order, we can create a visual representation of the word.
The same principle applies to substitution, where a symbol or letter is replaced by another. For example, we can substitute the letter "s" for the number "5" in the word "numbers". This allows us to encode the number 5 using a different set of letters.
Coding by letter shifting and substitution is a valuable technique for individuals with limited reading ability. It combines visual and cognitive abilities to create a form of communication that can be easily understood by others
