Effectiveness and Usability of Multi-User Functionality in 360RVW

Ascertain the effectiveness and usability of the multi-user functionality in the 360RVW system during collaborative virtual tours by conducting controlled multi-user evaluations that measure user experience and performance while multiple avatars interact concurrently within the video-based urban environment.

Background

The 360RVW system is designed to allow multiple users to explore large urban environments simultaneously and interact via avatars, aiming to deliver photorealistic, socially engaging virtual tours without 3D models. While the paper evaluates single-user exploration through a user paper, it does not assess multi-user scenarios.

The authors explicitly note that the multi-user capability has not been validated, indicating a need for empirical studies to determine how concurrent users affect usability, presence, navigation, and interaction dynamics in collaborative tours.

References

Although the system is designed to support multiple users, as shown in Figure 1 (c), the effectiveness and usability of this functionality remain unverified. Future research should include evaluations with multiple users to explore the potential benefits and challenges of collaborative virtual tours.
