It involves the adaptation of natural and human-made environments to the cultural, social, physiological, psychological, economic, historic, and behavioral activities of people. This integrates the aesthetic and environmental preferences of individuals or groups within the interior spaces of a building. Designers of enclosed space employ theories derived from fine arts, architecture, and intuition to guide judgments and aesthetic decisions, while scientific theories and guidelines provide knowledge that guide analysis, prediction, and testing the interactions between people and space. By combining theories, design decisions aim to create meaningful environments for a wide variety of users.
Interior design engages both the public and private scales of buildings.
However, at the private scale the focus of interior design shifts to issues regarding the satisfaction of group and individual needs. How well it satisfies the user's needs and their preferences for function, structure, materials, and aesthetics determine the quality of an interior environment. In 1948 a four-year program in Interior Design was initiated at the University of Florida s College of Art. This curriculum led to a Bachelor of Arts in Interior Design. In 1949 the College of Fine Arts and Architecture was created.
