Summary
Key Insights
-
•
Gestures provide a non-verbal window into users' mental models, often revealing thoughts not expressed in speech.
-
•
Representational gestures, especially those made in personal gesture space, indicate cognitive processes and implicit imagery.

-
•
Speech-gesture mismatches often signal ongoing mental model construction or word searching by users.
-
•
Gestures can reveal emotional attachment or disengagement with technology, influencing adoption and retention.
-
•
Mental models can be anchored by recent technology prototypes, such as chat GPT for AI understanding.
-
•
Structured interview protocols that elicit gesturing and separate talking from tool use optimize gesture data collection.
-
