Evaluating Interactive Digital Exhibit Characteristics in Science Museums and Their Effects on Child Engagement

Interactive digital exhibits (IDEs) in science museums are widely used to improve visitor engagement. The human–computer interaction characteristics of such exhibits play a key role in holding the attention of visitors, especially children. To determine these characteristics of IDEs and their effects on child engagement, 60 representative digital exhibits in two science museums were selected and analyzed, and eight characteristics were identified and scored. The holding time of the children was measured at each exhibit, and the average holding time (AHT) across exhibits was calculated. Then, the correlations between the IDE characteristics and engagement levels of the children were evaluated. The results show that three characteristics, namely, competition, social interaction, and visitor control, of IDEs have important effects on child engagement. The reasons for these results were also analyzed, and design considerations and principles for IDEs were identified.
