This special issue presents interdisciplinary studies about the complex phenomenon that takes place during the aesthetic and synesthetic involvement of a human observer in the perception of cultural heritage and art mediated by virtual and augmented reality or other forms of multimedia technologies.
The objective is to create a snapshot of the current state of the art about transdisciplinary methodological approaches.
