盲文容错率包括盲文方案的方案容错率和盲文读者的拼读容错率两个方面。为了合理评估汉语盲文方案的拼读效率、进一步改进盲文方案,提出盲文方案的方案容错率概念并对其进行统计学分析,得出容错率存在的必然性和可控性,指出容错率较大的盲文方案较容易使用和推广,最后给出了盲文方案容错率的优化函数以利于改进现有盲文方案。同时还分析了读者在阅读盲文时,其心理因素对盲文容错率的影响,揭示了盲文方案的方案容错率和盲文读者的拼读容错率之间相互影响、相互促进、相互代偿的关系。
Braille fault tolerance, including the program’s fault tolerance of Braille solutions and Braille readers’ spelling tolerance, are two aspects. In order to reasonably evaluate the spelling efficiency of Chinese Braille, further improve the Braille scheme, put forward the concept of scheme error tolerance of Braille scheme and make a statistical analysis on it, and then draw the inevitability and controllability of the fault tolerance rate. The Braille scheme is easy to use and popularize. Finally, the optimization function of the Braille scheme fault tolerance is given to improve the existing Braille scheme. At the same time, it also analyzes the influence of psychological factors on Braille’s error tolerance when reading Braille. It also reveals the relationship between Braille’s scheme error tolerance and Braille readers’ spelling tolerance, mutual promotion and mutual compensation.
