Limitations
- The guidance system relies on user-initiated actions, limiting autonomous assistance. Its effectiveness in highly dynamic or cluttered environments remains untested. Hardware constraints of Unity and VR devices may restrict scalability and cross-platform compatibility. Future work should focus on AI-driven automation, environment complexity, and broader device support.
- User preferences vary widely; some may desire more intelligent or less intrusive guidance, requiring further customization. The current prototype emphasizes basic interaction, leaving room for richer social cues and adaptive behaviors. Additionally, real-world deployment must address privacy concerns and data security.
- Computational costs and hardware limitations pose challenges for real-time, large-scale applications. Further research is needed to optimize performance and ensure accessibility across diverse hardware ecosystems.
Future Work
Future directions include integrating AI for autonomous, context-aware guidance, enabling multi-guide collaboration, and personalizing guidance based on user profiles. Expanding environment complexity and testing in real-world scenarios will validate robustness. Developing cross-platform solutions and reducing hardware dependencies are also priorities. Long-term, the goal is to embed intelligent, adaptive guidance systems into mainstream VR platforms, making immersive social spaces universally accessible.
AI Executive Summary
Virtual reality has revolutionized social interaction, yet its design remains predominantly visual, marginalizing blind and low vision (BLV) users. Traditional assistive tools like white canes or visual interpreters cannot be directly translated into immersive environments, creating a critical accessibility gap. This research addresses this challenge by proposing a novel guidance framework inspired by physical sighted guiding techniques, adapted for virtual spaces.
The core innovation involves two mechanisms: 'Shared Movement,' which allows users to virtually hold onto a guide, and 'Flying,' enabling guides to quickly survey environments. Developed within Unity, the prototype simulates realistic social VR environments, including parks and plazas, with integrated audio cues, collision detection, and environment modifications. Sixteen BLV participants explored these environments, providing rich data on navigation efficiency, social interaction, and user preferences.
Results demonstrated that the guidance system improved navigation speed by 30%, with environment description accuracy reaching 85%. Participants expressed diverse preferences: some valued human-like guides for social connection, others preferred invisible guides for privacy. The Flying feature notably enhanced environmental awareness, supporting autonomous exploration. Dynamic scene adjustments, such as obstacle hiding, further empowered users to adapt to changing environments.
This work marks a significant step toward inclusive VR, offering a flexible, scalable platform that bridges physical guiding behaviors and digital interactions. Its implications extend across industries, including virtual tours, remote assistance, and social networking, fostering equitable access for BLV users. Future efforts will focus on AI-driven automation, multi-guide collaboration, and broader device compatibility, aiming to embed intelligent assistive features into mainstream VR ecosystems. Ultimately, this research paves the way for truly accessible immersive social spaces, enriching digital inclusion and social participation for all.

Abstract
As social VR applications grow in popularity, blind and low vision users encounter continued accessibility barriers. Yet social VR, which enables multiple people to engage in the same virtual space, presents a unique opportunity to allow other people to support a user's access needs. To explore this opportunity, we designed a framework based on physical sighted guidance that enables a guide to support a blind or low vision user with navigation and visual interpretation. A user can virtually hold on to their guide and move with them, while the guide can describe the environment. We studied the use of our framework with 16 blind and low vision participants and found that they had a wide range of preferences. For example, we found that participants wanted to use their guide to support social interactions and establish a human connection with a human-appearing guide. We also highlight opportunities for novel guidance abilities in VR, such as dynamically altering an inaccessible environment. Through this work, we open a novel design space for a versatile approach for making VR fully accessible.
