This paper details and discusses experimental results obtained towards personalizing a museum visit through a personal mobile guide, using an approach relying on users' cognitive style, gaming, social networks, and recommendations. It describes the personalization system, which relies on a Facebook game to infer users' cognitive style, visiting style and interests, and a recommendation algorithm offering sequences of points of interests to visit. A qualitative and quantitative analysis of an experiment conducted in a museum is given, offering first conclusions and perspectives on the approach.
