The Dalia project focuses on visualization, interaction and collaboration in heterogeneous distributed environments. It proposes to explore the new possibilities offered by the rapid growth in networking, user terminals and data repositories. Networking infrastructures offer today a seamless worldwide connectivity using from high bandwidth connections on optic fibers to mobile connections through wireless networks. User terminals have also deeply evolved, from the classical PC to mobile terminals (laptops, pdas, cell phones) and large high-resolution and immersive displays driven by PC clusters. Digital data are now available from various large data repositories storing static data (maps, GIS, cad models) or dynamics data acquired through sensor networks (rfids, GPS, weather sensors, vehicle traffic sensors, etc.). Dalia focuses on distributed applications where users, located at different sites, are meeting in a virtual space to cooperate on a task involving large data sets provided by distributed servers. Each user joins the collaborative space using its own terminal. The application should adapt to the terminal (rendering capabilities, display size and resolution, available interaction devices) and to the network bandwidth, to ensure users a smooth navigation.
A typical application is crisis management (Tchernobyle, 2004 Tsunami, Katerina Hurricane) involving coordination centers located in different towns equipped with large visualization facilities (from display-walls to multi-projectors virtual reality environments), and mobile rescue teams equipped with handheld devices. These different users all have to communicate with each other, visualize and navigate thought complex data (terrain and building maps, satellite images, weather sensors, traffic informations, rescue team positions, etc.) to coordinate their efforts. But today, setting-up such collaborative applications is still challenging. In this project we propose to address some of the open issues:
Developing solutions in this context requires validations through experiments. The project will benefits from the software and hardware platforms the partners already developed. The Dalia experimental platform will gather the existing platforms located at Orléans (PC cluster and display wall), Bordeaux (PC cluster and reconfigurable multi-projector environment) and Grenoble (PC cluster, display wall and camera network).
The partners involved in the DALIA project are:
The full-body Grimage platform will be presented at Siggraph Emerging Technologies in New Orleans from the 3rd to the 7th of August. More information can be found here.

The GrImage platform in it's portable version was presented in Paris at the "Ville europÃ©enne de la science" (European science city) exposition that took place in Paris from Friday 14th to Sunday 16th of November.
The platform was presented in the Inria's "Digital village". At this occasion, we were filmed by the french TV channel TF1. Here is a link to the TV report.
Dalia is a project funded by Agence Nationale de la Recherche over the 2007-2009 time period.
