Especificação e desenvolvimento de um ambiente educativo móvel para a prática da escrita Braille

Resumo

This paper presents our first efforts to develop GBraille Suite, which consists of accessible educational software focused on learning and practicing of Portuguese through the Braille writing system. This paper presents the design, the development and the initial evaluation of a virtual keyboard based on Braille metaphor and, from this keyboard, it was developed a mobile application to practice spelling and synonymy using multimodal interfaces (screen gestures, voice and device vibration). The initial usability evaluation conducted with visually impaired students of elementary school indicates good acceptance of the applications.
