    Abstract
    Navigation is a limited metaphor for hypermedia and website use that potentially constraints our understanding of human-computer interaction. Traces the emergence of the navigation metaphor and the emprical analysis of navigation measures in usability evaluation before suggesting an alternative concept to consider: shape. The shape concept affords a richer analytic tool for considering humans' use of digital documents and invokes social level analysis of meaning that are shared among discourse communities who both produce and consume the information resources

    Abstract
    User problems with large information spaces multiply in complexity when we enter the digital domain. Virtual information environments can offer 3D representations, reconfigurations, and access to large databases that may overwhelm many users' abilities to filter and represent. As a result, user frequently experience disorienting in navigation large digital spaces to locate an duse information. To date, the research response has been predominantly based on the analysis of visual navigational aids that might support users' bottom-up processing of the spatial display. In the present paper, an emerging alternative is considered that places greater emphasis on the top-down application of semantic knowledge by the user gleaned from their experiences within the sociocognitive context of information production and consumption. A distinction between spatial and semantic cues is introduced, and existing empirical data are reviewed that highlight the differential reliance on spatial or semantic information as the domain expertise of the user increases. The conclusion is reached that interfaces for shaping information should be built on an increasing analysis of users' semantic processing
