Emotional Viscosity Model for Social Agent Design

1 reports · 1 sources

Tomoko Yonezawa submitted a paper that combines research on agents' acceptance of and avoidance of gaze, approach, and contact with an emotional viscosity model describing the accumulation, persistence, suppression, and expression of negative emotions over time, arguing that avoidance should not be viewed merely as interaction failure but as a relational signal marking human-agent boundaries. On this basis, the paper proposes a design perspective in which agents maintain, suppress, or express negative states according to social relationships and interaction history, and discusses design cases such as triadic jealousy, discomfort suppression, patience timing, and spatiotemporal viscosity, further asking about the traceability, boundedness, contestability, and repairability of interventions. The paper was published at the TBSA_2nd workshop at HAI 2026, totaling 5 pages and 2 figures.

  1. From Acceptance and Avoidance to Affective Viscosity: Designing Social Agents That Intervene in Human Relationships

    The paper connects research on an agent's acceptance of and avoidance of gaze with the affective viscosity model, which describes how negative emotions accumulate, persist, are suppressed, and are expressed over time. It argues that avoidance should not be seen merely as an interaction failure, but as a relational signal marking the boundary between humans and agents. On this basis, the paper proposes a design perspective in which agents maintain, suppress, or express negative states depending on social relationships and interaction histories. It discusses design cases including triadic jealousy, discomfort suppression, patience timing, and spatiotemporal stickiness, and then raises questions about whether interventions can be traceable, limited, contestable, and repairable.
