As LLM-based Conversational Avatars increasingly act as collaborators in hybrid indoor navigation, understanding how their personality traits influence human-avatar proxemic behavior is becoming crucial. Prior work has largely examined personality effects in static or one-sided interactions such as sitting, standing, or approaching. However, there is a gap in research on how avatar personality and motion-related factors (e.g., walking speed) shape proxemics when both the human and avatar are in motion. To address this, we developed an AR indoor navigation system featuring a Conversational Virtual Avatar (CVA) with three distinct personalities: Dominant, Warm, and Conscientious. The CVA guides users to destinations within the environment. In a between-subjects study (N=27), we found statistically significant effects of avatar personality and walking speed on proxemic behavior. Our work contributes to a broader understanding of the role of personality and walking speed of a CVA on human-avatar proxemic behaviour during navigation.

While collaboration in shared extended reality spaces has been extensively explored, larger environments like entire floors or buildings have garnered less attention. To address this gap, spatial navigation and collaboration across realities must be made possible so that users can find each other and foster shared spatial understanding independent from reality. Current developments target either navigation or collaboration but lack the combination. In this poster, we present an extended reality remote collaboration system using an augmented reality (AR) based indoor navigation for on-site and a Building Information Model (BIM) of the physical environment Virtual Reality (VR) system for remote users. We conducted a user study with ten participants (five pairs) to gather initial insights into the system’s usability and preferences for collaborative tools. The results offer initial insights into creating shared spatial understanding across realities. Our work contributes to a collaborative XR navigation system for extensive shared spaces.
