Experimental setup of the street crossing simulation. a A participant wearing the eye-tracking system is standing in front of the simulator. Screen 2 is straight in front of the participant. Screen 1 and 3 are tilted by 120° with respect of screen 2, around a vertical line at the edge with it. Images are projected onto the three screens by the projectors P1, P2, and P3. An infrared light beamer, on the right hand of Screen 3, sends light to a detector on the opposite side (red dotted line). When the participant decided to cross the street, he or she was instructed to take a step forward, interrupting the infrared beam between the beamer and the detector. b Calibration pattern projected onto screen 2. The central point is at 0° eccentricity. The other four points are at 32°, in the top left, top right, bottom left and bottom right corners
