Língua de sinalização em português (LGP)

      ( 

The Portuguese Sign Language (LGP) faces a low diffusion level, among the deaf

as well as the hearing communities. The communication of a deaf person, to be effective, requires the knowledge of LGP, not only on the speaker’s side, but also from the listener’s.

It is also essential that both speak the same sign language. Due to the shortage of

information, or lack of availability of the language, it is common to see people of distinct regions, using different gestures for the same words.

It is in this babylon that, in linguistic terms, the deaf people live nowadays. As

communication is an essential factor to learning, it is fundamental to explore all the possible ways of taking the LGP to a large number of people.

The presented work, focuses on the use of the new technologies in the diffusion

and teaching of the sign language. Even thought there is an agreement on the need of human intervention in the teaching of a sign language, it is also true that there is no dispute in relation to the added value that the new technologies represent as support material in the teaching.

In this dissertation, it is given special emphasis on the technologies that use images and/or models based in three-dimensional graphics to create virtual signers.
