The document describes a new methodology called "Bubbles Sorting" developed to evaluate the information architecture of VR/AR/MR projects. Participants organized images using plastic balls to simulate the 3D environment. Insights from the study found that people organize images looking at them individually and defining the group, with the most relevant images becoming larger and closer. Two types of favorites emerged: ones to save and ones to share. The methodology provided useful findings for designing the information architecture and interactions in a VR image gallery.
