In order to give full play to the carrier role of modern public art design and inherit the traditional elements whose vitality is gradually losing, this paper analyzes the modern public art design integrating the traditional elements under the interactive technology. Firstly, it analyzes the origin of modern public art design, which is manifested in the rational product of science and technology and the materialized form of cultural aesthetics. Then, it analyzes the current development situation of blindly seeking internationalization, over-reliance on modern tools, and insufficient design education level, and discusses the classification of modern public art integrating traditional elements and the inheritance problems it faces; under the interactive technology, the traditional elements and features are transmitted imperceptibly through a variety of carrier forms to realize the modern public art design integrating the traditional elements. The experimental results show that the resource utilization and benefit of modern public art are increasing exponentially year by year. With the increase of government investment in modern public art design activities, the complete contour map can be obtained by extracting the marked points.

The traditional indoor virtual reality art design is quite different from the actual placement of items. Based on the perspective of immersive communication, this paper analyzes the specific ways of applying virtual reality technology in art design from the two dimensions of physiological immersion and psychological immersion, so as to analyze the process of Virtual Reality Art Design Based on Immersive communication. The Kinect device is used to collect the indoor spatial feature depth data. After repair and filtering, the processed data is converted into the data in the spatial coordinate system to build the geometric model of the spatial feature data. This paper analyzes the indoor virtual reality art design by using virtual reality technology. The experiment proves that the placement error of the indoor virtual reality artistic achievements is small.
