This research and development project around collective interaction focuses on the creation of technologies using various interfaces and on the production or co-production of dedicated content. The first step of this project was to develop a technology based on laser pointers making it possible to discover in the room, collectively, interactive works. This technology is now used for dedicated productions: directors, video game creators, mapping artists, associated with developers, use it to create new forms of collective interactive writing. This content is distributed in France and internationally.
