Going Back in Hypertext

Abstract

Hypertext interfaces typically involve navigation, the act (and
interaction) of moving from one piece of information to another.
Navigation can be exploratory, or it may involve backtracking to
some previously-visited node. While backtracking interfaces are
common, they may not reflect differences in readers’ purposes and
mental models. This paper draws on some empirical evidence
regarding navigation between and within documents to suggest
improvements on traditional hypertext navigation, and proposes a
time-based view of backtracking.
