Spatial Augmented Reality (SAR) consists of projecting directly in physical space information coming from the digital world. Beyond conventional display methods based on screens or planar projections, this approach opens new perspectives for future applications in areas as diverse as aircraft maintenance or scientific mediation. However, even though inherent problems of computer vision and computer graphics are being solved today, the problems related to interaction remain largely unexplored. The characteristics of the used medium challenge the traditional approaches, and new techniques must be explored. The ISAR project focuses on the design, implementation and evaluation of these new interaction paradigms. The ISAR overall goal is to systematically explore the design space of interaction with SAR. Making SAR interactive is the unavoidable step towards the full adoption of SAR in various contexts including industrial and cultural contexts.

To achieve our objectives, we have built a multidisciplinary consortium composed of two research institutes, Inria-Bordeaux and LIG-CNRS, whose teams are specialists in 3D and Human-Computer Interaction (HCI), and a company, Diotasoft, which brings its expertise in the domain of registration in augmented reality.
