Abstract

People's information needs change as they encounter new situations. The need for an ambient information environment becomes more evident in the case of the mobile traveller where situated information access is one of the main challenges.

The motivation for this work has been to provide relevant information to the right situation and user in an ambient manner. Our way to solve this is to deliver personalised and context-aware information to the mobile user. To this end we have developed a platform, and prototype applications for travellers, and tourists. The system integrates our own tag technology with information from content service providers covering both general travel guide and local information.

The development methodology is user-centred, iterative, and progressive in nature. It combines information retrieval (IR) test and evaluation techniques with iterative and user-centred development techniques at the test and evaluation phase. Combining the two disciplines gives us the ability to test and evaluate both the information aspects and the interaction aspects of any information system in parallel. Another advantage would be that one can develop content and software in parallel.

This paper focuses on the IR test and evaluation framework that has been used in conjunction with the user-centred development. We emphasize the importance of performing IR test and evaluation for mobile systems in terms of users’ situations and tasks. The paper presents the results of some of the findings from a preliminary user test in an outdoor scenario. The test took place in a popular tourist destination in Spain.
