ABSTRACT
We present two touchscreen smartphone keyboard interface designs which dynamically alter key sizes as the user types and highlight likely key targets, based on word completion predictions. Although we find a speed reduction and no accuracy advantage with these methods over standard QWERTY, the text entry experience on mobile devices with these designs is significantly better for users.
