Representation Challenges: New Frontieres of AR and AI Research for Cultural Heritage and Innovative Design

Augmented Reality (AR) and Artificial Intelligence (AI) are technological domains that closely interact with space at architectural and urban scale in the broader ambits of cultural heritage and innovative design. This second collection of essays, that originated under the aegis of Representa tion Challenges, by reintroducing the combination of Augmented Reality (AR) and Artificial Intelligence (AI) explores its new frontiers. The ambitious goal of this second step was to explore the new boundaries that AR and Al mark in the fields of cultural heritage and innovative design, opening to international studies. This goal has been fully achieved and surprisingly surpassed, thanks to the lymph provided by new proposals and new scholars, which we hope - at least in a small part - to have contributed to fuel and stimulate. Papers' most cited keywords brings out the interests concerning digital tech nologies, primarily AR and Al, as central themes, and original relationships with digital acquisition methodologies (photogrammetry and UAV photogrammetry), with interpretive and informative visualization (BIM, H-BIM, 3D modelling, VPL, digital fabrication, and mapping), and with visual communication (VR, immersive environment, interactive representation, and hologram). This book collects 49 papers and 5 keynotes lectures and identify five lines of research that may guide future developments.
