PAULA: A Computer-Based Sign Language Tutor for Hearing Adults

This paper describes a new computer-based sign language tutor developed for hearing adults. The tutor, known as PAULA (Practicing ASL Using Linguistic Animation), utilizes the flexibility of 3D graphical animation to provide a better demonstration of signs than is possible with printed or current video sources. PAULA provides opportunities for sign language recognition study and practice that are not currently available to sign language students.
