Abstract:
Future computing environments will free the user from the constraints of
the desktop. Applications for a mobile environment should take advantage
of contextual information, such as position, to offer greater services to
the user. In this paper, we present the Cyberguide project, in which we
are building prototypes of a mobile context-aware tour guide. Knowledge
of the user's current location, as well as a history of past locations,
are used to provide more of the kind of services that we come to expect
from a real tour guide. We describe the architecture and features of a
variety of Cyberguide prototypes developed for indoor and outdoor use on a
number of different hand-held platforms. We also discuss the
general research issues that have emerged in our context-aware
applications development in a mobile environment.
