Analyse de référents de l'activité de co-design dans un contexte de Réalité Mixte

This paper focuses on referents used in co-design in a Mixed Reality context. A co-design device was installed inside a space to be redesigned, thus offering at once real and virtual representations of the space. Our goal is to understand how the real and virtual representations are used as resource in multidisciplinary co-design. An analysis of pointing gestures done by participants was conducted. Our results underscore complementarities at first between the real and the virtual, as design elements are matches to markers in the real space. Then virtual representations are mostly used to support the design and the construct of a common ground, highlighting the ability of the virtual representations to support design.
