Our goal is to understand the world through data. We combine visualization, machine learning, various modeling techniques, and advanced data infrastructure to look at problems in new ways.We build tools that integrate a variety of techniques with usable interfaces to make new analysis accessible. Currently, we are focusing on tools to measure the brain and body at work. Data from EEG, eye-tracking, motion capture and the environment provide a new and data-intensive glimpse of life in an event-rich world. We hope that a better understanding of the interaction between brain and body during real-world behavior will lead to technology for monitoring attention and fatigue as well as reducing cognitive load for people operating in normal and high-stress conditions.The work of the VML has been supported by NIH, NSF, and the Army Research Laboratories.
