A case study of public interfaces formed by public spaces according to their physical and conceptual qualities in Berlin - Alexanderplatz

A desire to recognize and explore the space is one of the most basic instincts of human beings. When a person begins to make sense of physical space, he establishes a connection between himself and the quality and quantities of the elements through mental assessment. For this reason, while the historical and social developments that occurred in the time cycle change the social, cognitive and physical needs of the human, they also distinguish indirectly public spaces which are the common areas of the communities.Public spaces form public interfaces by defining gabs. Public spaces create visual and perceptual effects on users by the public interfaces that they created. The public interfaces with their horizontal and vertical components reveal the circumstances that change perceptually by defining the physical and visual characteristics of the urban pattern for users.In this study, Section 1 describes the aim of the thesis, summary of the literature and hypothesis. Section 2 expresses the place of humans in the environment with the individual and social sense and the ways of the perceiving the environment with sensory and cognitive sense. In Section 3 firstly, the concept of public space, its development process and its basic components are addressed, and then the concept of public interface and user requirements, perceptual, physical and conceptual properties, which define and constitute the public interface, are investigated in detail in their subsections. Chapter 4 defines the historical and spatial development process of the Alexanderplatz in Berlin-Mitte area which is selected as the case study. In Section 5, the upper and lower scale analysis of Alexanderplatz and its surrounding, are based on the elements that define and constitute the public interfaces in Alexanderplatz, are discussed in detail. Finally, Section 6 includes the information, conclusions and recommendations obtained from about Alexanderplatz.
