Projective Augmented Reality in a Museum: Development and Evaluation of an Interactive Application

Abstract

Projective Augmented Reality (AR) offers exciting new ways of interacting with a museum exhibition. This paper presents such a projective AR application that was developed in cooperation with the ''Museum für Abgüsse Klassischer Bildwerke'' (''Museum of Casts of Classical Statues'') in Munich. It allows visitors to digitally paint a sculpture using a tablet while the result is simultaneously projected onto the real object. A first prototype of the application was tested in regard to usability, integration into the exhibition and its ability to transfer knowledge. The prototype was then improved based on the findings of this first user study and further evaluated in a second, comparative study, this time with a stronger focus on knowledge transfer. Applying regression and the bootstrap method demonstrates an increased effect on learning when using the developed application in comparison to the exhibition method traditionally used by the museum.
