What concrete three-dimensional motion and virtual-reality problems improve medical training and body-surface assessment? The Motion Capture and Analysis Laboratory develops optical motion-capture hardware and software to analyze full-body motion for healthcare research. The group builds virtual-reality simulators — for example, a neonatal endotracheal intubation simulator — combining physics-based models and interactive VR for procedural training. The lab develops optical scanning and machine-learning pipelines to assess physiological features in highly obese subjects, targeting hepatic steatosis and fibrosis. Researchers run interdisciplinary projects that pair motion capture with clinical collaborators to translate sensing and ML into health-focused studies.
