While listening to Embodied Conversational Agents (ECAs) in Virtual Reality (VR), background events can reduce both task performance and comfort. We ran an exploratory study with n = 5 participants who listened to ECA dialogues in a virtual open‑plan office while performing a dual‑task paradigm (keyword‑detection and r...

To determine which scene-level and behavioral enrichments truly improve the VR experie...
