Measuring Human Motion Under Clothing
SessionHand and Human
DescriptionIn many applications involving clothing, it is essential to know how clothes move relative to the body hidden beneath. This is impossible using traditional optical motion capture methods due to visual occlusion due to clothes and other body parts, and very difficult using previous non-optical methods that have bulky sensors and poor spatial accuracy.
We propose and evaluate a system, Emob, for estimating body motion under clothing using very small electromagnetic sensors attached directly to the skin. It can also be used to measure the motion of clothing layers or sensors below the outer layer of clothes. We show how electromagnetic tracking can even be performed inside a full body scanner, combining high resolution shape measurement with body tracking under clothing. We describe a new calibration procedure that learns to correct the highly non-linear distortion in electromagnetic sensors to improve accuracy by an order of magnitude compared to recent work. We show that our method is effective and demonstrate several novel applications.
