In this work we intend build a Portuguese to \libras automatic translation tool, where \libras is the Brazilian Sign Language, used by Brazilian deaf people. The generated output must be signalized by a 3D graphical avatar and the translation process must consider syntactical aspects of the languages, avoiding the \emph{signalized portuguese} (one sign per Portuguese word), which wouldn't be interesting to deaf people. An important difference between our work and other related works is that our intention is to produce an \emph{open source} system, that is going to be available for the community to use and to collaborate with the system progress, including building new pro-deaf systems based in our modules, as we have projected a modular system aiming to produce reusable code.

Keywords: Computation; \libras; Sign language; Machine translation.
