It is widely discussed whether the usefulness of mobile systems and services should be evaluated in the field or in the lab. The aim of this paper is to make a case for conducting longitudinal field trials when evaluating the usefulness of mobile services, and to partly base such evaluations on quantitative usage data automatically captured on the device. A framework for automatic capture and analysis of such data is introduced, and it is shown how it has been used to evaluate a mobile service… CONTINUE READING
