Ubiquitous user assistance in a tourist information server

This paper discusses the provision of ubiquitous services for desktop and handheld interfaces. The focus of the paper is on the interactive agenda offered by INTRIGUE, a tourist information server which assists the user in the organization of a tour by providing personalized recommendations of tourist attractions and helping the user to schedule her itinerary. The interactive agenda can be accessed both remotely, by interacting with the central server, and locally to the user's device.
