ABSTRACT

This paper describes an experiment that provides evidence to support the distinction between different kinds of device made by Cox & Young (2000). It is hypothesised that limiting the number of interactions participants are allowed during a period of exploration of an interactive device can result in enhanced levels of performance on tasks only if the interactive device itself is a devicey-device rather than a domainy-device. The results demonstrate that after a period of unstructured exploration, participants are able to complete a number of tasks with greater efficiency than the baseline. However, only those who have been limited by the number of interactions they have with the device can complete the most complex tasks with high levels of efficiency comparable to those who have conducted focused exploration.
