Inadequate support for browsing Browsing is “the process of exposing oneself to a resource space by scanning its contents” [3]. Browsing thus goes beyond simply presenting information to the user. It is a complex task whose mechanics are not well understood by most users [3]. In the spirit of Shneiderman’s visual infor- mation-seeking mantra, Bates [1] and Chang and Rice [3] recommend that browsers need to support four stages of information exploration: 1) Glimpsing the information in the environment; 2) Selection and sampling of this infor- mation; 3) Examining selected information in more detail; 4) Deciding whether to keep or discard the selection. When interacting with a large number of POIs, it is crucial to be able to browse through them.
