Crystal Viewpoints: Virtual Reality Viewpoint Design for Analytical Measurement of Crystal Structures in Materials Science and Engineering

This Work-in-Progress Research paper provides an exploration of viewpoints that are feasible candidates for visualizing the crystal structures in a Virtual Reality Learning Environment (VRLE). Visualization of crystal structures in Materials Science and Engineering is an important topic for various STEM disciplines. Traditional approaches to visualize these structures are limited to two-dimensional representations via paper sheets or computer screens. Beyond traditional methods, VRLEs are a promising approach for teaching about crystal structures, as their visualization is inherently three-dimensional and can afford a more immersive user experience. However, the optimal selection of viewpoints and perspectives that promote effective exploration and enhanced interactions with the crystal structures inside the VRLEs remains unclear. Our work addresses this gap by comparing three distinct viewing configurations in a VRLE: (A) from the bottom base of the structure, (B) hovering on top of the stacked crystal structure, and (C) from the center of the structure. To compare the viewpoints, we analyze the user preferences between the visualization approaches. Overall, this paper provides guidelines on the design of experiences related to crystalline structures in VRLEs for better student engagement and enjoyment with Materials Science content.
