Structural Changes in User Perception of Minimal Motion in HRI Across Proxemic Conditions

Q: What does this research mean for the field?

User perception and interpretation of a social robot's minimal motion expressions vary significantly depending on proxemic conditions, with unimodal expressions preferred at close range and multimodal expressions reducing ambiguity at longer distances.

Key Points

This research investigates how minimal motion in social robots is perceived across different proxemic conditions.
Mixed-factor design with two distance conditions (60cm, 200cm) and two expression modalities (unimodal, multimodal).
Conducted in a home-like scenario simulating a call-and-response context.
Sample size of 40.
Emotion recognition remained stable regardless of distance and modality, with non-significant differences.
In unimodal conditions, three out of five metrics showed medium-to-large effect sizes, with reliability confirmed for two metrics.
Multimodal conditions indicated strong effect sizes for some items, but did not meet reliability criteria.

Implication

Examines emotional recognition and communication potential in social robots across distance variations.
