2 Concepts Explanation

The urban visual phenomena can be viewed from the perspective of city as a complex system. It is believed that the urban visual system is the city image acquired by visual perception and the subsequent ideological and emotional processing of the physical environment and spiritual environment of the city. This is in essence a Gestalt interaction feature based on the object and subject of vision. The Gestalt visual analysis tools in urban planning and design integrate social, psychological, geographical, and local folk characteristics as well as the available technical and engineering methods to finally give rise to perceptible urban morphology.

From the perspective of complex adaptive system, the following conclusions about Gestalt visual analysis tools can be obtained using the object–subject unification principle and object–environment integration principle. On the one hand, the urban visual system has complex features and a binary structure. Therefore, urban morphology, lifestyle, and cultural activities of human being that depend on the temporal and spatial dimension all fall within the domain of visual analysis. On the other hand, the visual adaptive feature of the city reflects the movement and interaction between the physical elements as the visual object and the human as the visual subject. If the factor of the object–subject interaction is excluded, there will be no independent rule of visual adaption. The visual analysis established without the real perception of man has no practical sense.
