Research Seminar - May 04, 2001
Seminar Announcement
Abstract:Australian Sign Language (Auslan) is the dominant language for hearing impaired people in Australia. Late last year we were asked to develop a graphics system that could display an animated 3D human model signing in Auslan.We spent the first few weeks researching biomechanics, robotics, and realtime graphics. The biomechanics of the upper body defined the requirements for realistic motion. Robotics gave us a means of simplifying the complex biological model by approximation. Since the final application needs to be realtime, our graphics research highlighted the need for a fast graphics API and simple polygonal models. The system we developed, "Auslan Jam", is an object-oriented hierarchical tree renderer written in C++ and OpenGL. The tree models the forward kinematics of an connected set of nodes, where each node represents a rigid body. In this seminar, we will describe the development of Auslan Jam. We will focus on design, programming methodology, data capture and possible applications. This will be followed by a demonstration of the system. Finally, Sam Yeates will discuss developing a signing application using Auslan Jam. |
