Information Systems fail to support such endeavors mostly due to limitations and inadequacies in using sign languages, thus precluding the deaf from social inclusion and citizenship. A computational model to describe the sign languages is needed to build effective technological artifacts for the needs of the deaf. This study presents an evaluation of a computational description model in Libras. Thus validated, the model addresses as challenge for the Information Systems community the development of technological tools to bridge the gap towards inclusion and citizenship of the deaf.

The model was used to create a sample of representative signs to aid the recording of a base of videos whose aim is to support the development of tools to support genuine social inclusion of the deaf.

The goal of such observations was to determine requirements that KM tools should address for the specific CP formed by Deaf and non-Deaf members of the CP. The CP studied is a formal knowledge organisation based on learning and the evaluation of socio-linguistic aspects pertaining to the Brazilian Sign Language (Libras). Non-Deaf and members of the Deaf community cultivated such knowledge organisation through specific collaborative meetings and the use of Internet-based tools for KM. Knowledge was created to validate an intellectual artefact (a computational description model of the phonetic structure of Libras (PSL)) to be used as basis in the development of tools to aid the Deaf community in their learning, communication, informational, educational and other needs necessary for full exercise of citizenship. The Internet-based KM tools were paramount for the cultivating of the CP. Nevertheless, additional requirements for the KM tools emerged, such as: video-conferencing, video manipulation features, better management of asynchronous communication, among others.

Information Systems, whose role should be to facilitate those processes, still do not present a natural interaction for the deaf. There are many attempts by Computer Vision researches that are limited in their approach, their object of study, their lack of end use results etc. The challenge is to devise a framework with which to work towards addressing those shortcomings. The present study presents such a framework to support sign language recognition and interaction to serve as "de facto" standard that should be used by Computer Vision in order to claim back the field´s noble task of developing effective technological services that take the deaf´s needs into consideration towards social inclusion.
