Raskar and colleagues at MIT Media Lab are building a wearable fabric to support millimeter accurate location and bio-parameter tracking at thousands of points on the body. Such a fabric can compute and predict 3D representation of human activity and use them for a closed-loop control to augment human performance. The goal is to support a detailed analysis and control of higher-level human activity. The basic technology uses a new optical motion capture method they have recently developed. The first phase of the project involves building next generation optical communication tools.
