Using and determining location in a context-sensitive tour guide

The Lancaster Guide project which used the members of the general public to test a network-centric electronic tourist guide was discussed. The study provided insights into the challenges associated with developing location-based applications. The guide relied on a geographic model that contained two distinct object types, which were navigation point objects and location objects. The end-user system of the guide provided capabilities such as access to information; tailored city tours; access to interactive services; and cooperative tools. Location information was obtained using technology such as the Global Positioning System (GPS) and the wireless network.
