Application of Virtual Reality Technology in Contemporary Environmental Design

In the era of rapid development of science and technology, the theory of interior space design is constantly enriched and improved, and the design methods are gradually diversified. Light environment design is an important part of interior space besides color, material and other elements. In this paper, the concept of perceptual representation of knowledge in virtual reality is proposed and discussed in depth. In terms of theoretical framework, this paper analyzes the practical requirements and theoretical basis for the construction of knowledge perception representation theory, and on this basis, the concept of knowledge perception representation is defined.
