Screenshot from Hazard Perception video clip with the viewer's eye movements: the green circle shows the location of gaze on the road. In this clip the motorcycle on the left just passed the driver's car. I conducted a Region of Interest (ROI) analysis to derive the first fixation latency near the potential hazard.
Honda Riding Simulator: in these screenshots the continuous blue line marks the eye movement, the size of the blue circle represents the fixation duration. To measure fixation latency I used Noldus The Observer Video Analysis Software.
