Navigation Tools for Text Embedded within Complex-Shaped Area Features and Meandering Linear Features

Abstract: By presenting textual information within the space of corresponding images, the concept of DUAL-USE OF IMAGE SPACE (DUIS) eases the mental integration of textual and pictorial information. This paper applies the DUIS approach which was initially developed for area features to linear features. Moreover, we enhance the DUIS approach with new tools to navigate within embedded texts: The sidebar, the information petals and navigation bars. These tools provide the context as well as the structure of the entire textual information space at a glance thereby reducing the cognitive overheads associated with navigating within large texts.
