实现计算机藏文快速输入的关键问题研究

Research on Key Issues of Implementing Computer Tibetan Fast Input

通过对藏文文法的深入分析研究,利用藏文字符在藏文文法上的排斥性,在通用计算机键盘键有限的键位上合理安排了所有基本藏文字符,并结合藏文字符字频统计、计算机键盘布局理论以及藏文字母与英文字母在发音上的近似性,设计了无重码藏文输入法键盘键位布局,解决了在不使用上档键和冗余键的情况下实现计算机藏文快速输入的难题;通过对藏文编码标准的分析研究,实现了基于《信息技术信息交换用藏文编码字符集基本集》和《信息技术藏文编码字符集扩充集A(B)》国际/国家标准的快速藏文输入法。

By utilizing the repellency of Tibetan characters in the Tibetan grammar, all the basic Tibetan characters are reasonably assigned to the limited keyboard keys of the universal computer. A non-repeated code Tibetan keyboard layout is designed according to the similarity in pronunciation of English and Tibetan alphabet and the rules of computer keyboard layout. And a non-repeated code fast Tibetan input method in accordance with international and national Tibetan character coding standards is implemented on the base of the analysis of Tibetan coding standards. The problem achieving fast Tibetan input without using shift or redundancy keys is also resolved.
