Fluid links for informed and incremental link transitions

Abstract

We have developed a novel user interface technique for hypertext, calledfluid links, that has several advantages over current methods. Fluid links provide additional information at a link source to support readers in choosing among links and understanding the structure of a hypertext. Fluid links present this information in a convenient location that does not obscure the content or layout of the source material. The technique uses perceptually-based animation to provide a natural and lightweight feeling to readers. In their richer forms, fluid links can provide a novel hypertext navigation paradigm that blurs the boundaries of hypertext nodes and can allow readers to fluidly control the focus on the material to support their current reading goals.
