The GUIDE system has been developed to provide city visitors with a hand-held context-aware tourist guide. The system has been successfully deployed in a major tourist destination and is currently at the stage where it is publicly available to visitors who wish to explore the city. Reaching this stage has been the culmination of a number of distinct(More)
In this paper, we describe our experiences of developing and evaluating GUIDE, an intelligent electronic tourist guide. The GUIDE system has been built to overcome many of the limitations of the traditional information and navigation tools available to city visitors. For example, group-based tours are inherently inflexible with fixed starting times and(More)
47 The GUIDE project [4, 6] has been developed to provide city visitors with up-to-date and context-aware hypermedia information while they explore the city of Lan-caster in England. Visitors view this information via a handheld GUIDE unit based on the Fujitsu TeamPad 7600 tablet PC, which measures 213x153x15mm, weighs 850g, and is powered by a Pentium(More)
One of the most promising possibilities for supporting user interaction with public displays is the use of personal mobile phones. Furthermore, by utilising Bluetooth users should have the capability to interact with displays without incurring personal financial connectivity costs. However, despite the relative maturity of Bluetooth as a standard and its(More)
W e began our work on the Lancaster Guide project in 1997 with the aim of exploring the issues arising from developing and deploying context-sensitive applications. Specifically, we aimed to develop and deploy a context-sensitive tour guide for the city of Lancaster, UK. Motivated by the work on CyberGuide at Georgia Tech, 1 we envisioned a system that(More)
Context-awareness can be used to simplify a user’s understanding of, and interaction with, interactive systems. In effect, through adaptation, context-aware systems can migrate complexity away from the user and into the system (or agent). However, the incorporation of context-awareness raises a number of issues. For example, users are required to trust the(More)
In this paper we describe a technology probe aiming to aid understanding of how digital displays can help support communities. Using a simple photo gallery application, deployed in a central social point in a small village and displaying user-generated photos and videos, we have been able to gain an understanding of this setting, field test our device and(More)
Despite much interest over recent years in the area of context-aware computing, there are still a number of significant gaps in our understanding of the HCI issues associated with such systems. One particular issue that remains relatively unexplored is how to design around the apparently conflicting goals of adapting to changes in context while at the same(More)
