    Impact of Gender and Age on performing Search Tasks Online
    (Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Singer, Georg; Norbisrath, Ulrich; Lewandowski, Dirk
    More and more people use the Internet to carry out tasks of their daily work routine. To find the right information online Web search engines are the tools of their choice. Apart from finding facts, people use search engines to also execute rather complex and time consuming search tasks. So far search engines have been following the one-for-all approach to serve its users and little is known about the impact of gender and age on people s Web search performance. In this article we present a study that examines (1) how female and male Web users carry out simple and complex search tasks, and (2) how the age of the users impacts their search performance. The laboratory study was done with 56 ordinary people carrying out 12 search tasks each. Our findings confirm that age impacts the search performance significantly while gender influences were smaller than expected.

    Search Trails as Collaboration Artifacts – Evaluating the UX
    (Mensch und Computer 2015 – Proceedings, 2015) Franken, Sebastian; Norbisrath, Ulrich; Prinz, Wolfgang
    Users tend to share search results such as links or excerpts from web pages when performing complex search tasks. We developed a system called SearchTrails that enables sharing of complete search logs in the form of directed graphs, resembling the users’ trails through the Internet. We conducted a study with 29 participants in which we used both written reports and search trails as collaboration artifacts. We researched the value of search trails as artifacts for collaborative search compared to written reports. We did this by evaluating the user experience (UX) with both artifacts. By evaluating a user experience questionnaire (UEQ), we can confirm that search trails can support collaborative search better than written reports containing the essential information of the search trails.

    The Impact of SearchTrails on the Quality of Collaborative Search
    (Mensch und Computer 2016 - Tagungsband, 2016) Franken, Sebastian; Norbisrath, Ulrich; Prinz, Wolfgang
    Several collaborative search systems build upon real time collaboration during search processes. With SearchTrails, we present a novel way of capturing and exchanging the process of search itself between collaborators. We achieve this by asynchronously exchanging search trails between collaborators and thus overcome the necessity of real-time interaction. In a study with 29 participants, we evaluate the value of search trails as collaboration artifacts to answer the research question whether search trails improve the quality of collaborative search results. We show that this is the case and users can build upon the previous work of co-searchers in a very efficient way by analyzing and extending the search trails as given collaboration artifacts.
