Dynamics for Warfighter Avatars with Complete Articulated Anatomy

Virtual human avatars will play a critical role in the next generation of advanced training environments, performance-related physiological modeling, and simulation-based design of protective armor. The overall goal of this project is to design and develop computer software for generating dynamic, mission-relevant avatar movements utilizing USARIEM’s static finite element avatars. During the initial Phase II project, we developed and demonstrated 1) scripting complex avatar motions using high level commands, 2) assembling equipment onto the avatar, 3) anthropometry morphing of avatars, and 4) a graphical user interface for avatar assembly and animation. In this sequential Phase II, we will enhance the avatars to create a complete virtual human with physiology and biomechanics. The software will be enhanced by adding 1) prediction of avatar movement, 2) biomechanical characteristics (joint loading, muscle forces, and metabolic cost), 3) a physiology engine to account for environmental factors, clothing, and physical activity, and 4) enhance equipment assembly capabilities with higher fidelity clothing, material, and contact simulation. The software will build on our existing technology and new capabilities will be tested with various avatars (male and female) and in different motions and environmental conditions.
