Sign Language 3D Virtual Agent


Accessibility is a growing concern in several research areas. In computer science, programs that provide accessibility are those that enable people with disabilities to use computing resources efficiently. Since virtual environment relies primarily on the visual mode, usually using writing content, it may seem that access for deaf people is not an issue. However, for prelingually deaf individuals, those who were deaf since before learn any language, written information is often of limited accessibility than if presented in signing. Further, for this community, signing is their language of choice, and reading text in a spoken language is akin to using a foreign language. Sign language uses gestures and facial expressions and is widely used by deaf communities. The aim of this work is to develop a 3D virtual agent for presenting sign language information. The avatar consists of an articulated model, representing a human character, which is able to articulate signs. The virtual agent control is done through text scripts that describe the signs in particular notation developed in the context of this work. A sign language 3D virtual agent provides important improvement in human–computer interaction for deaf people, and may also be a tool for teaching and research of sign languages.
