Abstract:This study aims to analyze and understand pedestrians’ fixation patterns on urbanscape objects while navigating unfamiliar urban environments, using eye-tracking technology. Thirteen participants engaged in a navigation task from the Basilica di San Lorenzo to Piazza della Signoria in Google Street View, and their eye movements were recorded and analyzed through Semantic Segment Anything (SSA). Three hypotheses were tested, focusing on correlations between dwell time, fixation duration, and deviation from the optimal route. The study revealed that buildings were the most observed and fixated objects across participants, serving as pivotal navigational guides. There was significant variation in fixation duration and count between participants who successfully completed the task and those who did not, indicating the importance of efficient scanning and rapid information processing. The methodology, which also included spatial consideration through Hausdorff distance and think-aloud data, offered a comprehensive understanding of visual behavior and navigation strategies. Findings contribute valuable insights into individualized navigation processes and provide practical recommendations for urban design and planning, emphasizing the importance of visually distinct building facades and pedestrian-friendly thoroughfares.
