Plus qu'un problème de confort, le BÉPO est une disposition dangereuse pour la frappe de ces langues, plus dangereuse que l'AZERTY, notamment du fait de la position du W dans cette disposition. Cependant, la disposition BÉPO n'est pas du tout adaptée à la frappe de l'anglais, langue pourtant très utilisée par les Français, ni à celle des autres langues des pays voisins de la France, que les Français utilisent aussi. L'association Ergodis a très bien joué son rôle de lanceur d'alerte sur cette situation. This paper presents our initial keyboard design and our explorative evaluation of SingleTapBraille conducted with braille instructors and visually impaired users.ĭépasser l'AZERTY est aujourd'hui un impératif de santé publique, même s'il est bon de proposer un AZERTY amélioré en plus de la nouvelle disposition.
With SingleTapBraille, a user enters characters including text, numbers, and punctuation by tapping anywhere on the screen with one finger or a thumb several times based on braille patterns. In this paper, we describe SingleTapBraille, a novel nonvisual text input approach for touchscreen devices. However, most of the available touchscreen keyboards are still largely inaccessible to blind and visually impaired people because they require the user to find an object location on a touchscreen in order to interact with an application.
Visually impaired people tend to use touchscreen devices because these devices support a screen reader function, providing a cheaper, smaller alternative to screen reader machines. Touchscreen technology has brought about significant improvements for both normal sighted and visually impaired people. In doing so, we consider possible design improvements for the future development of accessible keyboards for blind users. Based on the evaluation results and the feedback of our participants, we discuss the strengths and weaknesses of previous keyboards that have been used by participants, as well as those of SingleTapBraille. The SingleTapBraille keyboard was better than the QWERTY keyboard in terms of both speed and accuracy, indicating that SingleTapBraille represents an improvement over existing alternatives in making touchscreen keyboards more accessible for blind users. Overall, participants were able to quickly adjust to SingleTapBraille and type on touchscreen devices using their knowledge of Braille patterns within fifteen to twenty minutes of introduction to the system.

We conducted an evaluation study with 7 blind participants to examine the performance of both keyboards on Android platforms. To assess SingleTapBraille, this study compares its performance with that of the commonly used QWERTY keyboard. This application allows blind users to input characters based on braille patterns. This paper provides an evaluation of the SingleTapBraille keyboard, designed to assist people with no or low vision in using touchscreen smartphones. It also presents the implementation of Grade 2 and an initial evaluation of the improved SingleTapBraille keyboard with a blind user. This paper presents our initial keyboard design to enter Grade 1 and our explorative evaluation of SingleTapBraille conducted with braille instructors and visually impaired users. With SingleTapBraille, a user enters characters including text, numbers, and punctuations by tapping anywhere on the screen with one finger or a thumb several times based on braille patterns.
