Abstract

This article presents the results of a research project which aimed to create a writing system for sign languages that could be written in handwritten and typed form as well as it could be learnt easily. We concentrated efforts in the investigation of the articulatory nature of the sign of Brazilian Sign Language (Libras) in order to be able to create its system of written representation that could undergo automation of processing. Our investigation led us to identify the articulatory structure of Libras signs which is constituted of four hierarchical levels. Based on this structure, we elaborated the writing system for sign languages, which is as well based on arbitrariness and linearity aspects. As a result, we obtained a system capable of representing Libras in the written mode, in a linear way, encompassing its three-dimensionality with a high degree of precision and attending to the condition of automation of the processing in reading and writing.
