Abstract: It is of great significance to conduct research on computer interactive technology for the blind.However,due to lack of international standard,braille fonts of different companies are incompatible with each other,and this has caused a lot of problems.If braille can be presented through Chinese characters point-location encoding,it could be freed from restrictions of braille fonts.The paper presented the transcoding process from braille to Chinese character point-location encoding through nondeterministic finite automata.Then,it is verified through the method of Reverse Order-Splitting-Sets method.It is tested that the transcoding accuracy rate reaches 100%.In this way,braille is computer independence,so that the blind could use computers in a more convenient manner.

Key words: Nondeterministic finite automata,Deterministic,Reverse order-splitting-sets method (ROSS),Braille transcoding
