Spatial Interaction Model and Application of VR and AR in Environmental Art Design

The purpose of this article is to explore the application of Virtual Reality (VR) and Augmented Reality (AR) technology in environmental art design. By building a spatial interactive model, the design efficiency is improved, the user experience is enhanced, and the digital transformation in this field is promoted. To achieve this goal, this article deeply analyzes the user interaction needs of environmental art design, and clarifies the expectations of designers, customers and end users for interactive experience. Based on this, this article designs a comprehensive spatial interaction model framework. The framework integrates the advantages of VR and AR technology and develops an efficient algorithm model to support the intuitive expression and real-time interaction of design. In the experiment, we compared the effect of using traditional design methods with that of using spatial interaction models. The results show that the spatial interaction model significantly improves the designer's design efficiency and quality, and at the same time enhances the customer's understanding and satisfaction with the design scheme. User testing further verified the usability, interactivity and functionality of the model, and proved its practical application value in environmental art design.
