Gaze as Evidence for Common Grounding: A Cross-Corpus Analysis of MapTask and MUNDEX
Cross-corpus analysis finds gaze patterns modestly correlate with grounding alignment in the MapTask and MUNDEX dialogue corpora.
Researchers mapped HCRC MapTask and MUNDEX annotations into a shared partner/task/away vocabulary and computed gaze features around task-relevant dialogue units. Aligned reference interpretations and understood judgments co-occur with more task-directed gaze, lower gaze entropy, and fewer transitions, clearest for task-leading participants. Effects are small and several weaken when recurring participants rather than dialogues are the unit of inference, so gaze is treated as one contributing cue to grounding.

In collaborative tasks with asymmetric information, participants coordinate their understanding through interaction. We ask whether gaze provides evidence about grounding across two such tasks. Working from discrete behavioral annotations, we map HCRC MapTask (Anderson et al.
