LibrAR: aplicativo de aprendizagem de libras usando realidade aumentada e realidade virtual em dispositivo móvel

This article presents an application that uses Virtual Reality and Augmented Reality to aid the teaching of alphabet letters and numerals in LIBRAS. It has three modules: the first uses a 3D hand to display the letters and numerals in LIBRAS; the second and third are games for the user to train their knowledge in LIBRAS. During the tests with a group of students, only some initial difficulty was observed due to the lack of knowledge in the use of RV and RA technologies, but in the end, everyone was able to use the application and had fun with the tasks that were given to them. We concluded that the application has achieved its goals since the users showed great interest in the application to learn LIBRAS.
