Abstract

Personalised web interfaces are expected to improve user interaction with web content. But since the delivery of personalised web content is currently not reliable, a key question is how much users may be confused and slowed down when personalised delivery goes wrong. The aim of the study reported in this paper was to investigate a worst-case scenario of failed personalised content presentation – a dynamic presentation of content where content was dynamically presented, but content units were selected at random. We employed eye-tracking to monitor the differences in users’ attention and navigation when interacting with this “dysfunctional” dynamic interface, and a static version. We found that subjects who interacted with the dysfunctional version took 10% longer to read their material than those with static content, and displayed a different strategy in scanning the interface. The relatively small difference in navigation time in first-time viewers of dynamically presented content, and of the results from the eye-tracking patterns, suggests that users are not significantly confused and slowed down by dynamic presentation of content when using a Focus-Metaphor interface
