Abstract:
World Wide Web (WWW) searches are the primary source of information for many people for which different search engines are available. Depending on the search query, which might be ambiguous, search engines can return thousands of results to the user potentially causing frustration and a dislike towards the search engine. In this study, using a Brain-Computer Interface (BCI) we investigated the Long-Term Excitement, Short-Term Excitement, Engagement, Meditation and Frustration of study participants while they were performing ambiguous searches using Google, Yahoo! and Bing. The captured emotional data as well as pre-test and post-test questionnaire data suggest that the different search engines and search terms had an influence on the emotions of a participant during searches with ambiguous search queries.
