low-fidelity location based information systems
In this article, we describe the intrinsic constraints of mobility and discuss how we can work around and often exploit these constraints using information implied by the context of the mobile user. In particular, we outline some of the work we have been doing in providing information to users on the basis of "Low-Fi" location information retrieved from user's cellular phone. A user's location and other contextual information is used to retrieve task relevant information and avoid many of the problems posed by limits of mobile devices and their use. This is part of an ongoing effort to build "smart" navigational interfaces bound on information about a user's location.
