Movement is present by nature in all creatures of the Creator, phenomenon or latent within cells, and even the fixed elements change with the passage of time and provide a sense of movement when exposed to factors and influences such as wind or rain, so the movement is a divine gift if it is best used by the designer, it provides an integrated design that carries the characteristics of permanence and flexibility. And sustainability, it is considered the design language of adaptation that enables the designer to reach a realistic design that is functional, aesthetically and technologically aware. Interior design is nothing but an imagination of a set of different and changing scenarios that solve the problems of space to provide the right environment for users. Problem : -  The lack of clarity of the correct concept of the movement's design thought and philosophy due to the relative scarcity of reference sources that directly address the movement as a design language, in addition to the lack of clarity of the full impact of its impact on interior design. - Limiting the internal designer to exploiting the movement from the functional and technological aspects and neglecting its aesthetic and psychological impact on the user. Goal: - Shedding light on the correct concept of the movement's thought and philosophy, its value and its relationship to the inner space. - Highlighting the characteristics and value of movement and the importance of its use as a basic factor in designing the internal space from all functional, aesthetic and technological aspects, in addition to its impact on the user. Methodology: The research follows the descriptive method and the analytical method. results: 1- Movement in interior design has two basic types: the moral mental movement and the objective physical movement in the visual field in addition to the movement of linear elements, surfaces, volumes, colors and lighting. The movement is perceived in design through understanding the factors that cause this perception, which are contrast, diversity and unity. And proportion, toning, light and color. 2- Movement in interior design has many philosophical values ​​such as merging, collision, extension, expansion, disassembly ... and others, and those values ​​control movement resulting from linear elements, shapes, surfaces, light and color within the space. 3- Any vacuum that represents an integrated kinematic system that combines formation, functionality and technology.
