Experimental Study on Guidance of Curved Bridges and Paths in Suzhou Literati Gardens to the Line of Sight

The study chose curved bridges and paths in three ancient gardens in Suzhou as research object. Tourists were asked to take pictures on the spot, to obtain information about the scenery and view directions they were most interested in visting the garden. Combining the relationship between the paths and the scenes, it applied the experimental method to analyze the visual behavior characteristics of visitors touring the curved bridges and paths. Through quantitative analysis, it is found that the changes of spatial positions brought by the curved bridges in Suzhou literati gardens affected people's visual behaviors. Among them, the visual distances and directions of the scenery had a significant impact on people’s mood to enjoy the scenery. Tourists had the highest interests in viewing the scenes when the sight distance was 3 to 33 meters. The vertical relationship between the path direction and the view direction, and the directional relations of paths to the scenes may enhance visitors' interest in viewing the corresponding landscape. There are some laws in the application of vertical and directional relations in curved bridges.
