Improved object arrangement and layout design considering interaction for indoor scene synthesis in immersive virtual reality

This study proposes an improved object arrangement and a layout design including movement path and location recommendation algorithm that considers the systematic interaction of virtual reality (VR) users participating in the created virtual scene for efficient and realistic indoor scene synthesis in immersive VR. First, we propose a new object labeling technique as an improved arrangement method based on existing object arrangement optimization. It has a top-down structure wherein commonalities between objects, reset of pairwise relationship objects, and cost calculation process for each object in objects movement are grouped for arrangement. Next, we design a layout that considers VR user participation as a way to apply the created virtual scene to immersive VR. This diversifies the object arrangement pattern by considering not only the rectangular wall layout but also the concave structure layout. In addition, we propose a method to recommend the location of VR users according to the interaction host such that VR users can interact effectively and organically within the defined layout. Consequently, through comparative analysis with existing approaches, the performance of the proposed method was verified and improved results were confirmed. The process of generating natural indoor scene synthesis results was confirmed through step-by-step application of the labeling method.
