VirHKey: un clavier gestuel hyperbolique avec retour visuel

The VirHKey uses a new Unistroke text entry method. Gesture recognition is accomplished through a sequence of flicks. This recognition is deterministic, enabling good accuracy. It is done continuously to provide a focus and context visual feedback by using the hyperbolic geometry. This is helpful at the learning stage: the user is able to learn swiftly the gestures to make to reach the right character. We expect that the visual feedback will be helpful for beginner users and should become unnecessary for expert users after few hours of use. Usability tests show very good results compared to existing propositions.
