Augmented reality basically consists of superimposing digital information onto a representation of the real world. Most of the time, this superimposition is only visual, e.g. synthetic images are added onto images on the real world. In this talk, we will present the various application domains of augmented reality before focusing on the scientific challenges it has to address. Integration of the real and the virtual world include several registration problems:

- The famous geometric one is called pose camera computation where the position and orientation of a camera must be computed with respect to the virtual world in order to be able to project additional content. It can make use of synthetic markers as well as more natural features extracted from the images

- The second one is the visual registration between both worlds, i.e. the influence of each world on the other (occlusions, shadows caused by either virtual or real objects, lighting consistency...).

At last, we will present some of our recent works in the field of augmented reality. We will more specifically present our recent works about augmented maps, as an ongoing collaboration between Keio University HVRL lab and our group. Augmented maps make use of standard unprepared paper maps on which digital content can be reprojected after the map has been recognized and registered with GIS (Geographical Information System). To this end, we first detected road intersections and use their spatial distribution to recognize and locate the map.

Prof. Guillaume Moreau obtained his PhD in computer science in 1998 from Rennes University. After a fi
rst position at Ecole des mines de Paris, he moved as Associate Professor to Ecole Centrale de Nantes in 2002, where he became full Professor in 2011. His research activity takes place at the CERMA laboratory which studies the "atmospheres" of architectural and urban environments. He is currently head of the computer science team of the lab. His research covers various activities in the
elds of virtual reality, from the integration of autonomous human beings to human perception in virtual environments (at the psychophysics, functional or sensitive level). He currently studies the link between digital images and information systems through virtual environments and augmented reality.
