The Tate Modern's Multimedia Tour programme includes three different types of handheld tours: a Multimedia Highlights Tour, a tour in British Sign Language, and a Collections Tour. Through both quantitative and qualitative evaluation we are gaining valuable knowledge about visitors' thoughts on handheld tours in museums. This presentation explores the ways handheld tours relate to other gallery activities and fulfill many of Tate Modern's interpretation aims. It goes on to review content approaches that work for our visitors and those that don’t. Particular areas discussed are opinions on interactive content such as texting and games, artists' contributions, links between audio and visual, use of film clips, and provision of text-based information.
