Abstract
Physical-motion skills are important in physical education, theater, military training, and a wide range of
vocational training. Teaching them is difficult because events happen quickly and the view of instructors is often occluded.
We are developing training systems using modern surveillance technology that can automatically track and assess students
exercising physical-motion skills. We describe two systems we have implemented, one with inexpensive nonimaging sensors
and one with multi-camera fusion, to track U.S. Marines during training and assess how well they are performing. The key
challenge is visually summarizing the data because there is usually too much for instructors to inspect manually. We describe
several visualization methods we provide, including plots of unusual events in time and space broken down by student and
type of event, plots of continuous-valued metrics, plots of group centroids, and comparison plots of similar exercises. Results
show that interesting phenomena can be seen in the visualizations that are otherwise difficult to recognize.
