Abstract

This paper describes an efficient system for entering data into a pen-enabled computer, and most effectively a handheld device. While keyboard input has been shown to be considerably faster than handwriting input, this is not true for the small PDA interfaces. For this reason, we designed and developed a prototype that uses chatroom abbreviations and shorthand symbols to increase the speed of data entry for these devices. This system was also developed as a prototype system for the speech impaired to rapidly convert hand-drawn symbols on a pen-enabled device into speech output. We created a library of chat-room abbreviations and shorthand symbols, and developed a knn classification system to recognize the symbols. Experimental results show the effectiveness of the system in terms of speed and accuracy.
