This article presents the new version of the DUCK keyboard. To evaluate this new prototype, we chose an evaluation with novice users, in two steps: A first step with a copy of sentences. Then we let them get familiarized with our system for 15 days. Finally, we re-evaluate their performance after this phase of familiarization. Results shows that, after a learning phase, the participants significantly improve their input performance with the DUCK keyboard. Text input speed and accuracy have been improved.
