A Powerful Pseudo-Syllabic Text Entry Paradigm

This paper describes a powerful pseudo-syllabic paradigm for improving the efficiency of typing in languages with transparent orthography (i.e., languages with highly regular correspondence of orthography and phonetics). By adopting a novel orthogonal framework, keyboards are defined as 2-D regular arrays of keys. Non-expert users can fast and intuitively input any possible combination of pseudo-syllables, which are text entry units with simpler consonant-vowel phonemic structure. Moreover, it is possible to input single characters in the typical letter-by-letter way. For transparent languages such as Italian and Spanish, the performed tests have shown a significant improvement in the efficiency of typing texts.
