InfoCruise: Information Navigation Presenting a Focus Facet Based on Context

In order to find desired information on mobile phones, it is necessary to set search keywords easily and to explore a search if a user's information needs are not well defined. We propose an information navigation method to help users succeed in finding information on mobiles. Our proposal method presents to users a focus facet by analyzing context about contents, users and dialog. The focus facet is presented each time users refine a search. Users can select their desired keyword from the facet, and check the search results, and then users can define their ambiguous needs through interaction. We evaluated our method compared to a traditional search method. In our experiments, a user's load for setting some keywords of our method is lower than the traditional search method. Users can experience greater search success and satisfaction using our method than the traditional search method.
