  4. Project goals • Track user’s gaze in realtime • Describe natural gaze behavior on wall-sized displays • Factors that influence gaze behavior • Exploit gaze behavior

  5. Tracking Gaze - Hardware + Videobasedeyetrackers Body motion trackers EyeSeeCam http://www.journalofvision.org/8/14/12/Schumann-2008-jov-8-14-12.pdf

  6. Tracking Gaze - Software(https://www.sourceforge.net/projects/libgaze) • Open-source framework for combining eye-tracking and head-tracking systems • Linux/MacOS/Windowsbasic • implementation in C • APIs in: • jGaze (Java)‏ • pyGaze (Python)‏ • libgazesharp (C#)‏ EyeTracker: Eyelink2 libGaze Application HeadTracker: Vicon Display: Planar

  12. Exploit Gaze Behavior • Multi-modal interfaces (demo in collaboration with HCI-KN) • Facilitate user experience with gaze-contingent actions (DFG proposal with HCI-KN) • Evaluate ‘real-estate’ value of large displays (VIZ-KN) • Overcome computational bottlenecks (CG-Tü)
