Researchers at the University of Southern California (USC) integrated visual effects techniques and magnetic resonance imaging (MRI) to create an ultra-realistic animated simulation of the human hand in motion.
The model combined laser scans of the hand's surface with an MRI-based model of the underlying bone structure.
The researchers used lifecasting materials to produce a plastic replica of a model’s hand, then made a negative three-dimensional mold to hold the hand in a single pose for MRI scanning; the procedure was repeated 12 times in different poses, and a data-driven skeleton kinematic model was built, with soft tissue simulation added to calculate musculoskeletal movements consistent with bone movements.
Said USC's Jernej Barbic, "Understanding the motion of internal hand anatomy opens the door for biologically inspired robotic hands that look and behave like real hands."
