On-line recognition of Pitman shorthand for fast mobile text entry

Abstract

A novel solution to on-line Pitman shorthand recognition for high speed text input (>120wpm) to computer and mobile devices such as PDA's is proposed in this paper. Approaches to the recognition of three major components of Pitman shorthand - consonant outlines, vowel and diphthong symbols and shortforms are described in detail. Evaluation shows that the proposed approach achieved 84.4% recognition accuracy.
