Abstract

We present the Cyberguide project, in which we are building prototypes of a mobile context-aware tour guide that provide information to a tourist based on knowledge of position and orientation. We describe features of existing Cyberguide prototypes and discuss research issues that have emerged in our context-aware applications development in a mobile environment. Keywords: Mobile computing applications, contextawareness, location-dependent applications, hand-held devices 1 Introduction The project we report on in this paper, Cyberguide, has as its main focus the rapid prototyping of handheld mobile applications in order to assess the utility of context-awareness in mobile devices. The challenge we are addressing in Cyberguide is how to build mobile applications that make use of the context of the user. Initially, we are concerned with only a small part of the user's context, specifically location and orientation. The application which drives the development of Cyberguide is a that of ...
