A virtual reality environment to support chat rooms for hearing impaired and to teach Brazilian Sign Language (LIBRAS)
Improving the way that totally or partially deaf people communicate with the world is a challenging task for our society. One way to improve their communication is to learn sign language, which is a visual language based on hand shapes, orientations, and movements of the hands, arms, or body, and fa...

description | Improving the way that totally or partially deaf people communicate with the world is a challenging task for our society. One way to improve their communication is to learn sign language, which is a visual language based on hand shapes, orientations, and movements of the hands, arms, or body, and facial expressions. This paper aims to present a 3D virtual reality environment to allow deaf users to communicate with each other in a real-time, synchronous, instantaneous fashion via an online chat room and to assist the teaching-learning process of Brazilian Sign Language (LIBRAS). A three-dimensional avatar was developed which can translate words or sentences from Portuguese to LIBRAS. It was performed two experiments to evaluate the communication via the chat room: (1) with chat history enabled (visible) and (2) with chat history disabled (invisible). These evaluations involved 30 end-users, which confirmed that the virtual environment as developed here is effective to distance classes. |
