We present the results of an experience in design and evalua- tion of multimedia guides for art exhibitions based on Apple iPod-class devices, gesture based interaction and rich mul- timedia content. Design is based on decoupling between content, interface and interaction design, adaptation to dif- ferent user skills, and reusability; the evaluation is based on logging users’ actions, time spent in the visit and content access. We report about the lesson learned in building and testing on the field two different guides during a period of six months.
