The Sotto Voce electronic guidebook, which was tested at Filoli mansion [2] [19], also provides content about the exhibits on a handheld device. Users are presented with images of the rooms in the historic house on their PDA’s. Users thus orient themselves in the physical and virtual world together as they locate the content relevant to an artifact. Each image shows artifacts against a physical wall of a room. The visitor can select artifacts from the virtual image and find out more about them, principally in the form of audio content. Visitors could share the content in the relatively quiet environment and it was found to play a positive role in social interactions.
