摘要
盲文是盲人学习科学文化知识不可或缺的工具,一个优秀的盲文方案有助于提高盲文摸读的效率。触觉阅读(摸读)完全不同于视觉阅读(视读),提高盲文摸读效率必须从提高摸读准确率和摸读速率两方面入手。盲文摸读效率因子是衡量盲文摸读效率和评测盲文方案的重要参考性指标。数学公式为量化评测各种不同版本的盲文方案提供了一种新的工具,弥补了用定性指标评价盲文方案的不足,从而把评测盲文方案的方法推上一个新高度。
Braille is an indispensable tool for persons with visual impairment to learn scientific and cultural knowledge,and an excellent Braille scheme is helpful to promote efficiency of Braille reading by touching.Reading by touching is completely different from reading by eyes.To improve the efficiency of Braille reading by touching,it is necessary to start from the two aspects of improving the accuracy and speed of reading by touching.The efficiency factor of Braille reading by touching is an important reference index to measure reading efficiency by touching and evaluate Braille scheme.The mathematical formula provides a new tool for quantitative evaluation of different versions of Braille scheme,which compensates the lack of qualitative evaluation for Braille scheme,so as to improve the method of evaluating Braille scheme to a new level.
