spatial hypertext

This essay discusses the visual characteristics of hypertext (space, contour, depth) by situating it, as an artistic form, in the literary traditions that it extends and modifies. While, from a literary perspective, hypertextuality is nothing new, what is revolutionary is the way that computerized hypertext emulates the spatial and visual qualities that literary texts have historically struggled to effect. To illustrate the concept of spatial form I have chosen to analyze the mola web, a hypertext which is unique, though not abnormal, in the extremity of its link structure. One needs only think of the ubiquitous metaphor of the labyrinth in hypertext criticism or of the recent attention given to spatial user interfaces to see how dependent is the idea of hypertext on a spatial form.

Hypermedia designers have tried to move beyond the directed graph concept, which defines hypermedia structures as aggregations of nodes and links. A substantial body of work attempts to describe hypertexts in terms of extended or global spaces. According to this approach, nodes and links acquire meaning in relation to the space in which they are deployed. Some theory of space thus becomes essential for any advance in hypermedia design; but the type of space implied by electronic information systems, from hyperdocuments to “consensual hallucinations,” requires careful analysis. Familiar metaphors drawn from physics, architecture, and everyday experience have only limited descriptive or explanatory value for this type of space. As theorists of virtual reality point out, new information systems demand an internal rather than an external perspective. This shift demands a more sophisticated approach to hypermedia space, one that accounts both for stable design properties (architectonic space) and for unforseen outcomes, or what Winograd and Flores call “breakdowns.” Following Wexelblat in cyberspace theory and Dillon, McKnight, and Richardson in hypermedia theory, we call the domain of these outcomes semantic space. In two thought experiments, or brief exercises in interface design, we attempt to reconcile these divergent notions of space within the conceptual system of hypermedia.

The Cave Writing Workshop is an advanced experimental electronic writing workshop founded by Robert Coover, exploring the potential of text, sound, and narrative movement in immersive three-dimensional virtual reality. It brings together teams of undergraduate and graduate fiction writers, poets and playwrights, composers and sound engineers, graphic designers, visual artists, 3D modelers and programmers, to develop, within the environment of Brown’s “Cave” in the Technology Center for Advanced Scientific Computing and Visualization, projects that focus on the word. From 2002 onward writers have explored the possibilities of spatial hypertext in an immersive environment. What this paper proposes is an exploration of the history of the twin currents of hypertext and virtual reality that merged to create this particular form of expression, going back to the early hypertext systems developed at Brown University in the 1960’s by Ted Nelson/van Dam/et al and work in immersive virtual reality at University of Illinois’ CAVE in the early 1990s.
