Abstract
A person's thoughts and emotions can be expressed in sign language (SL) in the most natural and intuitive way in the deaf community. PSL is a form of sign language which provides information through the use of hands and other body parts. It is estimated that there are ten million deaf people in Pakistan, but only 5% of them go to school. People who are hearing impaired lack a basic understanding of language and literacy due to the lack of educational resources in Pakistan. An automated system that can overcome this problem is needed to improve communication skills among the deaf community. A PSL dictionary creation system based on Hamnonsys is presented in this thesis. PSL dictionary contains the sign gloss of a given word and Hamnonsys. A virtual keyboard is used for entering Hamnonsys for given signs. A method is also being developed to add nonmanual components to the proposed system, for instance, there is a gaze, mouth gestures, facial expressions, and body posture to consider. When the user retrieves the sign and Hamnonsys from the dictionary, they can be converted to SiGML for input to a signed avatar that will animate the sign. It is possible to retrieve the sign and Hamnonsys from the dictionary. The proposed system could be used to animate signs and for creating Pakistan sign language dictionaries.
