Compare The Size: Automatic Synthesis of Size Comparison Animation in Virtual Reality

Size comparison animations have proven to be an effective method for conveying information about the relative sizes of objects, making it an essential tool for various domains such as science, education, architecture, and entertainment. At the same time, Virtual Reality (VR) technology has gained significant attention in recent years, enabling users to immerse themselves in realistic digital environments. However, the manual creation of size comparison animations in VR can be time-consuming and labor-intensive. In this paper, we propose Compare The Size, an automatic synthesis approach for generating size comparison animations in virtual reality. Our propose technical approach can automatically extract size information from input 3D shapes and create procedural animations that showcase their relative sizes. The generated animations can be experienced by users in a virtual environment, providing an immersive and engaging experience. In the end, we validate our proposed approach through a series of numerical experiments and user studies.
