About

Vasiliki Zygouras is a human-computer interaction researcher whose work explores the social dynamics of voice-user interfaces (VUIs) in multi-user, real-world settings. Her research focuses on how families and small groups perceive, interact with, and form relationships with smart speakers and social robots. In her highly cited 2021 paper, "Small Group Interactions with Voice-User Interfaces" (23 citations), she examined how VUIs use multi-modal cues—such as graphics, expressive sounds, and movement—to convey social engagement and shape group interactions. Her follow-up 2022 study, "Speed Dating with Voice User Interfaces" (14 citations), introduced a novel methodology to understand how families perceive VUIs in group settings, revealing critical insights into trust, turn-taking, and social presence. Zygouras’s work is notable for bridging the gap between single-user VUI design and the complex, often messy reality of home environments where multiple people interact simultaneously. Her contributions have implications for designing more socially aware and inclusive voice interfaces, and her research is increasingly cited in the fields of social robotics, family informatics, and conversational AI.
