Project Title


The measure of proximity (physical distance between two objects) is central to many studies in psychology. While it is extremely challenging for humans to estimate accurate proximity measure between objects just by looking at a video, recent development in affordable depth camera (e.g., Microsoft Kinect) has made it possible for us to obtain this measure. With depth sensor, the task of continously measuring the 3D spatial location of an object can be reduced to the video object tracking problem (i.e., we only have to localize where the object is on the image plane in order to determine its 3D location in the world).
We address this issue of obtaining accurate, temporally dense measure of proximity by combining state-of-the-art interactive tracking technique with modern sensing technology (depth camera). The focus of this work is on demonstrating how we can use dense measure of proximity to objectively analyze infant-mother interaction during The Strange Situation, a protocol for studying infant attachment security.
