I just returned from CHI 2018 where we successfully presented our full paper on PolarTrack.
Roman Rädle did a fantastic job to explain how the PolarTrack technology enables us to separate mobile displays (e.g. smart phones, tablets) from non-display objects in video feeds. This approach can be used to provide an alternative means to display segmentation for tracking purposes, e.g., for camera-based approaches to locate and track movements of mobile devices on a desk like in HuddleLamp. A video explaining the approach can be found here:
PolarTrack is also a great example of scientific cooperation in this day and age. PolarTrack whose initial ideas originated at the University of Konstanz in Germany was developed into a working prototype and publishable paper at Aarhus University in Denmark and the University of Applied Sciences Upper Austria in cooperation with Microsoft Research Redmond from the US.
