document: Smartback : supporting users in back navigation This paper presents the design and user evaluation of SmartBack , a feature that complements the standard Back button by enabling users to jump directly to key pages in their navigation session , making common navigation activities more efficient . Defining key pages was informed by the findings of a user study that involved detailed monitoring of Web usage and analysis of Web browsing in terms of navigation trails . The pages accessible through SmartBack are determined automatically based on the structure of the user 's navigation trails or page association with specific user 's activities , such as search or browsing bookmarked sites . We discuss implementation decisions and present results of a usability study in which we deployed the SmartBack prototype and monitored usage for a month in both corporate and home settings . The results show that the feature brings qualitative improvement to the browsing experience of individuals who use it .
