CARDS is a comprehensive Augmented Reality (AR) docent system to promote informative and engaging art experiences for exhibition visitors. While utilizing AR to add aesthetic visual effects has been actively explored, facilitating visitor engagement in educational exhibitions through AR has been relatively unexplored. Thus, the proposed system facilitates visitor engagement in informative exhibitions by providing AR-specific interaction features which include context-based sequential AR pins, position-based AR pin configuration, and orientation-based AR visual aids. The objective of CARDS is to enrich the onsite art experience of visitors by presenting information on exhibits in a systematic way, as well as to enhance visitor engagement by taking the bodily movements of visitors as interaction inputs.
