Whilst Augmented Reality (AR) offers the possibility of exciting new interaction modalities for mobile users, the prospect of providing a collaborative multi-view, in which multiple viewers may view the same shared AR workspace from multiple perspectives, offers another equally exciting prospect. Currently, this has only been
researched using marker-based AR approaches that present significant scalability issues, as they require the wide scale physical augmentation of our environment
with markers. However, recent advances in marker-less systems using natural feature tracking, coupled with the use of wireless, ad-hoc communication could be
used to create a collaboratively mapped multi-view AR space.
