Interactive Digital Engagement With Visual Artworks and Cultural Artefacts Enhances User Aesthetic Experiences in the Laboratory and Museum. *International Journal of Human–Computer Interaction*, 1–14. https://doi.org/10.1080/10447318.2022.2143767 Digital technologies reshape the way we interact with our environment, including our experiences with artworks in museums. Advanced computational imaging solutions allow having extremely high-resolution digital reproductions of artworks. We tested whether exploring such reproductions via an interactive interface heightened aesthetic appreciation and enhanced recognition. With this interface, observers can move, turn, zoom, and relight the digital reproductions (http://artmyn.com/). In Study 1, 82 university students (*M* = 22.30 y.) explored paintings in the laboratory. In Study 2, 63 museum visitors (*M* = 43.80 y.) explored precious cultural artefacts at the Martin Bodmer Foundation. In both studies, participants’ aesthetic appreciation (interest, pleasure, intensity, subjective learning) was higher towards artworks they had explored interactively as compared to non-interactively or as physical objects. However, we found no evidence that interactive exploration improved artwork recognition. More studies are needed to learn when and why digital interaction is beneficial above and beyond subjective aesthetic evaluations.
