  When working with emergent and appealing technologies as Virtual Reality,
Mixed Reality and Augmented Reality, the issue of definitions appear very
often. Indeed, our experience with various publics allows us to notice that
technology definitions pose ambiguity and representation problems for informed
as well as novice users. In this paper we present Immercity, a content curation
system designed in the context of a collaboration between the University of
Montpellier and CapGemi-ni, to deliver a technology watch. It is also used as a
testbed for our experiences with Virtual, Mixed and Augmented reality to
explore new interaction techniques and devices, artificial intelligence
integration, visual affordances, performance , etc. But another, very
interesting goal appeared: use Immercity to communicate about Virtual, Mixed
and Augmented Reality by using them as a support.
