(a) Route (highlighted in black) with starting point (blue pin) and destination (black flag) depicted on the background map of Google Maps (© 2016 Google). All intersections are annotated with “I-” and a number indicating their position along the route. The intersection annotationss did not appear on the map display for the participants and are only added to this figure to allow references to intersections within this paper. (b) A participant holds the navigation system and wears eye-tracking glasses with an attached laptop in the backpack during the experiment. The experimenter follows the participant and takes notes (re-enacted scene). (Photo: Marc Latzel)
