Laqua, Sven, Sasse, M. Angela, Greenspan, Steven and Gates, Carrie (2011): Do you know dis?: a user study of a knowledge discovery tool for organizations. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 2887-2896.

Organisations today have no reliable way of ensuring that all employees are aware of information that may be relevant to their work. In this paper we report on a 2-year project in which we have iteratively designed, developed and tested a knowledge discovery system (KnowDis) for organizations. Early stages of our study revealed that, employees do not know what is available on the corporate intranet, or files and messages they have stored. KnowDis proactively fetches relevant information and displays it in an unobtrusive form; this increases employee awareness without disrupting their tasks. We discuss and characterize knowledge workers' email usage behavior. Our main study with 28 users of KnowDis-enhanced email showed it can improve the user experience and performance on information retrieval tasks for knowledge workers.

Laqua, Sven and Sasse, M. Angela (2009): Exploring blog spaces: a study of blog reading experiences using dynamic contextual displays. In: Proceedings of the HCI09 Conference on People and Computers XXIII 2009. pp. 252-261.

In this paper we report on an eye-tracking experiment conducted with 60 participants to gain an understanding of how people interact with blog environments. We compared a standard blog interface with a novel contextual blog interface, which dynamically adjusts its contextual navigation to a selected article. We measured task performance and interaction behaviour for explorative tasks and goal-oriented search tasks. We further collected subjective feedback to evaluate user preferences. We found that participants using the contextual blog interface completed search tasks 19% faster and made 80% fewer errors. Moreover, participants using the contextual blog interface interacted more with the provided information during the exploration tasks. We did not find significant differences in user preference overall between both blog interfaces. However, a more detailed analysis of our results suggests significant demographic differences for performance, behavioural and subjective measures.
