The current research highlights an important aspect of the great and rapid development in the field of science and technology, and modern manufacturing methods as a result of the scientific revolution resulting from the accelerated cognitive development, Which prompted designers in general and interior design, the subject of research in particular, to exploit and invest in digital technology, And the development of digital control in the industrial product design process for the purpose of creativity and innovation through these digital programs, Digital models fulfill the requirements and desires of the interior designer according to the creative skill by using modern software with high efficiency and accuracy in line with the requirements of the user, the interior designer and the beneficiary companies ,Therefore, the research problem can be determined by the following question:What is the nature of the variables in modeling patterns in the stages of contemporary interior space design through the use of virtual reality techniques?
While the aim of this study was: to reveal the importance of digital models in the real interior space through a virtual reality, the current research included three sections: The first topic: the variables and their relationships in the design of the interior space, and the second topic: modeling in interior design between reality and simulation, and the third topic: Digital models in interior design, and the research reached a set of conclusions, the most important of which are:
1.Digital models allow the designer, custodians, and people to be able to explore the interior space before designing it.
2.Designers use Digital Prototyping to design, improve, validate and digitally visualize their spaces throughout the design stages.
3. Innovative digital models can be created through creative designs, achieving multiple design goals (best performance, high efficiency, space efficiency, appropriate design cost).
