A new student at a college wishes to have a tour of the campus to get acquainted with the buildings, lecture rooms, and other facilities she has to find and use when she begins her studies. The system suggests a tour that includes all buildings of general interest, such as library and hall, and some of specific interest for her studies. She starts off, finding her way with the help of a map. She can get more information about all places when she is near them, and as far as she is interested. At lunchtime she interrupts her tour and asks for a place to eat. She gets several offers, each with a short description. After she has chosen one, she gets directions of how to find it. After lunch she wants to resume her tour, and the system shows her to the next point in the tour.
