WordGlass: additional keys to present the most likely words
Résumé
In this article, we propose WordGlass, a system of additional keys that are dynamically added as the user types. Each key proposes one of the most likely words. The keys have been spaced out on the keyboard so that one additional key can be displayed above and another below the last key pressed, without obscuring the keys already present. First results show that, WordGlass has some benefits: the prediction use rate is much higher with WordGlass than with WordList. The majority of participants said that it was easier to see a word that was close to the pointer than to look beside the keyboard. This proximity to the cursor was also reflected in the distance covered by the pointer. On average, participants covered 48% less distance with WordGlass than with WordList. With this reduction of the travelled distance and the better use of the words proposed, the participants were 5% faster with WordGlass than with WordList.
