The popularization of multimedia technologies and their active implementation into the process of the object-spatial environment organization is a pressing issue in scientific researches in the field of interior design. It was defined that the application of multimedia technologies, such as sensory touch objects, are fundamental in the process of the creation of an interactive interior for public use. The paper is devoted to revelation of the compositional location techniques of the interactive sensory objects in the interiors of public buildings. The complex of theoretical methods of scientific research has contributed to the analysis of the design of interactive public interiors through the prism of formal composition. The results of the study revealed the compositional techniques for interactive multimedia objects placed in the interior. We conclude that the location of sensory objects in the interior more often carried out by the use of composite grids: a rectangular mesh scheme and a radial scheme. Interactive multimedia objects add an adaptability and attractiveness to the interior, which is an important factor in the formation of public space.
