Résumé
In this paper we propose a novel predictive text entry system with a new distribution of its keys around a word list. Our aim is to optimize the use of software keyboards allied to prediction list. A prediction list is generally used to reduce effort by presenting a list of candidate words that may continue the prefix of the user. However, this technique may tire the user by adding additional cognitive and perceptual efforts. The user has to search continuously for his aimed word in the list, moving his eye-gaze between the list and the keyboard. Our new design allows the user not to lose his focus from the keyboard, no from the list, as well as reducing the movements of the cursor. We also present the experiments carried out to compare our new system to the classical alphabetically ordered keyboard with a list next to the keys.
