  4. 1. Introduction • The results of a web search are generally presented as a collection of web-page surrogates. • The study investigates how searchers interact with graphical search engine results page user interfaces. Lizzeth Cabana Tejada - The Value of Visual Elements in Web Search

  5. 2. REVIEW OF RESEARCH • Others have also used eye-tracking to gain an understanding of what happens during a search. • Some other observations revealed by eye-tracking are that placement and proximity of image search results affects a viewers gaze path.

  6. 3. METHODOLOGY • They collected and analyzed two sources of data: • self-report • Observation • The users completed a series of search tasks using three graphically-enhanced search interfaces. Lizzeth Cabana Tejada - The Value of Visual Elements in Web Search

  7. 3.1 Participants • 36 participants, all undergraduate students at a major research university Lizzeth Cabana Tejada - The Value of Visual Elements in Web Search

  8. 3.2 Search Tasks • Task 1 asked the user to find the schedule of events at a local performance theater. • Task 2 asked to find two sites where a specific camera model could be purchased. • Task 3 asked the user to find two credible sites describing the side-effects of aspirin.

  9. 3.3 Data Collection • Data was collected using questionnaires, the think-aloud process, eye-tracking and participant observation. • They used the Tobii eye-tracking system and ClearView 2.7.1 software to record and analyze the eye-tracking data.

  10. 4. DISCUSSION • Each of these three interfaces uses an arrangement of pagesurrogates which differs from the usual top-to-bottom lineardisplay. Figure 1: Screenshots of ViewZi, SearchMe, and KartOO Lizzeth Cabana Tejada - The Value of Visual Elements in Web Search

  11. We can see differences in scanning behavior across the three interfaces. Lizzeth Cabana Tejada - The Value of Visual Elements in Web Search

  12. The analysis indicates: • The Kartoo display elicited the most scanning. Participants generally spent time looking at all 10 surrogates before clicking to go to a page. • The SearchMe Display elicited careful analysis of individual surrogates, but inhibited scanning beyond the first few results. • The Viewzi display facilitates scanning in a way that is similar to the typical ranked list Lizzeth Cabana Tejada - The Value of Visual Elements in Web Search

  13. In terms of ease of interaction on a scale of 1-9, where 1 is most difficult, 5 is average, and 9 is least difficult • 30% found Kartoo most difficult (1-2), • 70% found SearchMe least difficult (7-9) • 42% found Viewzi average.

  14. Conclusion • The main idea from the initial analysis is that the visual qualities of these displays strongly influence the user interaction. • Training how to search using the visual search engines enhanced the user’s search effectiveness Lizzeth Cabana Tejada - The Value of Visual Elements in Web Search

  15. Conclusion • When asked if they intend to use the visual search engine again, more trained users answered positively than non-trained users. • The most popular search engine that people want to use again was SearchMe. Lizzeth Cabana Tejada - The Value of Visual Elements in Web Search
