Capability at a Glance: Design Guidelines for Intuitive Avatars Communicating Augmented Actions in Virtual Reality

2026-03-06

AI Summary

This study addresses the challenge users face in intuitively understanding and activating superhuman augmentation capabilities in virtual reality. Grounded in affordance theory, the research integrates user-centered design with expert participatory design, engaging professional designers to co-create avatars that effectively communicate both the presence and interaction modalities of such enhancements. The work presents the first systematic set of 16 design guidelines—comprising both general and category-specific principles—for representing augmented abilities in VR. Through controlled experiments and external evaluations, these guidelines were rated by users as clear and practical, and avatars designed following them demonstrated significantly improved intuitiveness. The framework has been successfully deployed across four distinct VR scenarios, offering a reusable design paradigm for augmented reality interactions.

Abstract

Virtual Reality (VR) enables users to engage with capabilities beyond human limitations, but it is not always obvious how to trigger these capabilities. Taking the lens of Affordance, we believe avatar design is the key to solving this issue, which ideally should communicate its capabilities and how to activate them. To understand the current practice, we selected eight capabilities across four categories and invited twelve professional designers to design avatars that communicate the capabilities and their corresponding interactions. From the resulting designs, we formed 16 guidelines to provide general and category-specific recommendations. Then, we validated these guidelines by letting two groups of twelve participants design avatars with and without guidelines. Participants rated the guidelines'clarity and usefulness highly. External judges confirmed that avatars designed with the guidelines were more intuitive in conveying the capabilities and interaction methods. Finally, we demonstrated the applicability of the guidelines in avatar design for four VR applications.
