  3. Key Research Areas • Cognitive-affective Science e.g. Evolutionary Levels of Processing • Hazard Cognition and Driving Simulation • Two Visual Systems and their Eye-movements • Attentional Landscapes and Usability • VR-based Hypercom with Joint-Attention Support

  5. Distractor Effect

  6. Self-Referential Encoding

  7. Driving simulator studies

  8. Driving simulator studies (A) Mean fixation durations around the appearance of red light in the cases of successful braking, categorized by eccentricity. (B) Mean fixation durations for the passing through red light (“0” corresponds to the fixation at the moment of switching to red), categorized by eccentricity.

  9. Ambient Processing Focal Processing

  10. Two visual systems and their Eye-movements • Saccadic amplitude by fixation duration.

  11. Two visual systems and their Eye-movements d‘ as a function of visual prosessing mode

  12. Attentional Landscapes & Usability from Velichkovsky, Pomplun & Rieser,1996

  13. Attentional Landscapes & Usability

  14. Equipment • SIRCA Driving Simulator from ARTEC Group • 3 SR Research Eyelink Systems • 1 LC Technologies binocular Eyegaze System

  15. Eyetracker Driving Simulator Control PC Eyetracking PC SIRCA Driving Simulator

  16. SR Research Eyelink Systems • Features: • Accuracy: Typical average bias error .50 degrees. • • Head Based Video Tracking: The System can compensate for head movements. • • Temporal Resolution: 4ms at250Hz sampling-rate.

  17. LC Technologies binocular Eyegaze System • Features: • Calibration: Calibration is fully automated, fast, easy and can be saved for later sessions. • • Accuracy: The tracking is highly accurate and tolerant to many variations (e.g. pupil drift) typical average bias error .45 degrees. • • Remote Video Tracking: The System is unobtrusive and undistracting. • • Temporal Resolution: 8,3ms at120Hz sampling-rate (binocular)
