盲文阅读中的容错率理论及相关影响因素分析

Analysis on Error Tolerance Rate Theory and Its Relative Effecting Factors in Braille Reading

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 error tolerance rate includes two aspects： the scheme error tolerance rate corresponding to Braille scheme and the spelling error tolerance rate corresponding to readers. In order to reasonably evaluate the spelling efficiency of Chinese Braille scheme and further improve it,this paper presents a concept of scheme error tolerance rate and makes a statistical analysis on it. The results show that the error tolerance rate is objective necessary and controllable,pointing out the Braille scheme with the greater error tolerance rate will be easier to use and popularize. Finally,it gives an optimization function of scheme error tolerance rate,which is helpful to improve the current Braille scheme. Meanwhile,it discusses the influences of readers＇ psychological factors on Braille error tolerance rate when reading and reveals the relations of mutual influence,mutual promotion and mutual compensation between the scheme error tolerance rate of Braille scheme and the spelling error tolerance rate of Braille readers.
