Le système KeyGlass

Abstract : This paper presents the KeyGlass system : a text entry system with dynamic addition of characters based on those previously entered. The prediction system that we use to optimize our system is based on the joint use of a lexicographic tree and a system using bigrams. We present in this article the different steps that led us to this prediction system. Finally we study, through two experiments (one theoretical and the other one with users), the usefulness and effectiveness of our system during a task of text copy. The results show a significant reduction in the distance covered by the pointer on the soft keyboard. However, users are slower to enter text.
