Most interfaces include textual information, including for example the document title, URL, and a short query-biased summary of the content. Other interfaces include additional browsing features, such as topic clustering, or thumbnails of the web pages. In this study we analyse three search interfaces, and compare the effectiveness of textual information and additional browsing features. Our analysis indicates that most users spend a substantially larger proportion of time looking at text information, and that those interfaces that focus on text-based representations of document content tend to lead to quicker task completion times for named-page finding search tasks.

One of the main issues affecting the use of eye tracking in research is the quality of captured eye movements (calibration), therefore, in this paper, we propose a method that allows us to determine the quality of calibration, since the existing eye tracking system (Tobii Studio) does not provide any criteria for this aspect. Another issue addressed in this paper is the adaptation of gaze direction. We use a black screen displaying for 3 seconds between screens to avoid the effect of the previous screen on user gaze direction on the coming screen. A further issue when employing eye tracking in the evaluation of web search interfaces is the selection of the appropriate filter for the raw gaze-points data. In our studies, we filtered this data by removing noise, identifying gaze points that occur in Area of Interests (AOIs), optimising gaze data and identifying viewed AOIs.
