Figure 1 . PolarTrack is an optical tracking system for mobile devices that combines an off-the-shelf RGB camera with a rotating linear polarization filter mounted in front of the lens. PolarTrack exploits the use of polarized light in current displays to segment device screens in the camera feed from the background by detecting periodical changes of display brightness while the linear polarizer rotates. ABSTRACT PolarTrack is a novel camera-based approach to detecting and tracking mobile
