Your Kinect Is Watching You

In my lab, a team working with Konica Minolta has developed a system to automatically detect learning. In one study we used the Kinect to gather nonverbal data during one-on-one, student-teacher interactions. Later, we used that data to predict the students? test scores. The early results are encouraging, though preliminary, with around 10 movements (those relating to the shoulder and elbow, for instance) being the most predictive. What makes this type of experiment so powerful is the ?bottom up? nature of the research. Instead of looking for specific known gestures, like nodding or pointing, we can mathematically uncover subtle movement patterns, many of which would not be noticed by the human eye. Just imagine if teachers, based on a small sample of their students? nonverbal behavior, could instantly detect which students needed extra attention or specialized assignments.
