Data and documentation for "Designing museum intelligent agents for cognitive support, trust, and cultural identity: A prototype-based HCI study"

This dataset supports the article “Designing museum intelligent agents for cognitive support, trust, and cultural identity: A prototype-based HCI study.” It contains de-identified analytic data from 480 adult participants who completed three tasks using a high-fidelity museum intelligent-agent prototype and subsequently completed a post-use questionnaire.

The accompanying documentation includes a variable codebook, coding information, and data-validation notes. Data were collected between December 15, 2025, and March 15, 2026. The study was approved by the Tsinghua University Science and Technology Ethics Committee (Humanities, Social Sciences and Engineering), approval number THU-04-2025-1137.
