Learning Techologies: Motion Capture

by Gary Woodill on June 12, 2008

Motion capture technology promises to speed up the process of developing animated avatars for immersive learning. Existing motion capture software works by tracking the path of a large number of visible markers placed all over the body. Because of the complexity of tracking so many points, motion capture software often gets confused and errors are produced. A new approach using marker-less software from a lab at Stanford University, promises to reduce the error rate, and does not need the actor to wear tight clothing. In fact, capturing the movement of clothing, such as the ruffle of a skirt, leads to more realistic animations. A downloadable paper and video, both entitled Performance Capture from Sparse Multiview Video, describes this new approach.
