Reorganization of a keyboard layout based on linguistic characteristics would be an efficient way to improve text input speed. However, a new character layout imposes a learning period that often discourages users. The Quasi-QWERTY Keyboard aimed at easing a new layout acceptance by limiting the changes. But this strategy prejudices the long term performance. Instead, we propose a solution based on the multilayer interface paradigm. The Multilayer Keyboard enables to progressively converge through a freely optimized layout. It transform the learning period into a transition period. During this transition period, user’s performance never regresses and progressively improves.
