Who Explains Privacy Policies to Me? Embodied and Textual LLM-Powered Privacy Assistants in Virtual Reality
Virtual Reality (VR) systems collect vast behavioral and biometric data, but privacy policies are often overlooked due to their complexity. This research explores how LLM-powered privacy assistants, integrated into a VR app store, can enhance informed consent. By offering both text-based chat and embodied avatar interactions, the study found that these assistants significantly increase user engagement with privacy information, enabling more deliberate decision-making where privacy acts as a critical 'veto' mechanism for app selection.
Key Executive Takeaways
This study highlights a critical opportunity for enterprises developing VR applications to integrate AI-powered privacy transparency tools. By making complex privacy policies accessible and interactive, companies can foster greater user trust and facilitate informed consent. The research demonstrates that while immersive avatar assistants drive engagement, textual interfaces empower deeper reflection, suggesting a hybrid approach could maximize impact. Proactive disclosure of privacy risks directly at the point of decision is key to building user confidence in the rapidly evolving VR ecosystem.

Unseen Risks in Virtual Reality
VR systems collect high-fidelity behavioral and biometric data (e.g., eye-tracking, motion data) with millimeter-level precision. This data can transform subtle movements into highly identifiable biometric profiles, potentially revealing sensitive inferences like cognitive load, emotional states, or even sexual orientation. Despite these risks, VR privacy documentation remains static and opaque, buried in external menus, leading to a critical awareness gap where users underestimate granted permissions and the granularity of inferred information.
AI-Powered Transparency Solutions
Large Language Models (LLMs) offer a promising approach to bridging the privacy awareness gap. Conversational agents can summarize complex data practices, adapt explanations to user literacy levels, and answer situational questions, addressing key design challenges for privacy-related user interfaces in VR. Past research has shown LLMs can reduce cognitive load by summarizing risks and increase user confidence.
Designing for Informed VR Consent
Our system embeds an LLM-powered privacy assistant into a VR app store, presented in two interaction modes: a text-based floating chat panel and an embodied virtual avatar. The assistant provides a layered design, guiding users with a privacy dashboard and context-aware suggestions. An exploratory within-subjects study (N=21) compared unassisted browsing with these two assisted conditions, qualitatively assessing participants' decision-making and modality preferences.
Impact on Awareness & Decision-Making
Both the avatar and chat conditions supported participants' perceived privacy risk comprehension and awareness. Participants more frequently ruled out applications perceived as higher risk. Privacy primarily functioned as a veto mechanism in app selection, rather than a primary driver. The avatar fostered engaging interaction, while the chat supported reflective review and reading at one's own pace, enabling thorough understanding of complex information.
Optimizing VR Privacy Interfaces
The LLM-powered assistant serves as a supporting decision scaffold, making privacy considerations actionable. There's a trade-off between engagement (avatar) and comprehension (text), suggesting a potential for hybrid interfaces. Future work should explore objective comprehension measures, address hallucination risks with RAG, and balance user privacy with explanation quality (local vs. commercial LLMs).

Privacy as a Veto Mechanism in App Selection
Participants rarely described privacy as the primary driver for selecting a VR application. Instead, it functioned as a veto mechanism. Users consistently eliminated options by ruling out apps that received poor privacy ratings on the dashboard, even when other appealing factors were present.
The privacy assistant was particularly useful for assessing apps that lacked 'instinctive trust', helping users make informed decisions by highlighting high-risk options and effectively blocking them from consideration.
