In 2014, the Orange Foundation, which had already assisted several cultural institutions in integrating new technologies in their premises, offered the Musée d’Orsay to develop a tool using augmented reality for the use of its visitors, by way of sponsorship. The museum direction promoted the choice of one of the museum highlights, Gustave Courbet’s The Painter’s Studio. Not only because this painting is already prominent in the museum’s current news in 2015, as it is undergoing a major restoration in public following a crowdfunding operation, but also because its large dimensions, the number of characters represented, the complexity of its composition and of its symbolism, and the various mysteries it receals make The Painter’s Studio a particularly relevant choice for this project. Eric Jouvenaux will present this innovative mediation experiment that aims at being at once ambitions and surprizing, original in being both educative and poetical, and he will outline its creation process. He will also evoke the extension of the project as a web experience and the strategy deployed to promote the launch of this new tool on social networks.
