Identifying the stimulus of visual perception based on Eye-tracking in Urban Parks: Case Study of Mellat Park in Tehran

Urban parks that provide the context for relationships between people and nature could be good cases for studies and analysis of visual perception in the everyday landscape. The main goal of the research is to evaluate the people’s attention to the primary factors and landscape elements in urban parks. Accordingly, out of 59 regional and trans-regional parks in Tehran, ten major parks were selected as case studies. The main elements of the landscape were extracted and classified based on the Fundamental Values and Factors of Landscape (FVFL). An experimental study was designed to track the eye movement of park visitors, using portable eye-tracking glasses. The results showed that the most effective motivation during visual perception in the experiment was human-made factors with an average of 59.12% of total fixation duration. Besides, the average of fixations duration on natural factors, human activities, and behavioral factors was 20.65% and 20.23%, respectively.
