- 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
- Outlines the results of a pilot study designed to consider what constitutes a landmark in hypertext. Tests users' memories for locations visited on the WWW. Reports the results, and outlines a refined methodology for a new study. By understanding more about users' navigation through hypertext information space, the issue of recognition of informative materials on the WWW may be addressed

- Abstract
- For effective access to images, the design of the database interface must be based on principles that match the actual querying needs of users. Analysis of this design problem reveals that the query language must support utilization of both visual and verbal clues. The ViewFinder interface, designed as a client to a database server, supports querying based on both types of clues. Presents details of ViewFinder design. Describes results of usability analysis performed on ViweFinder with a group of 18 users. High search success rates were achieved (greater than 80%) through both types of querying means (visual and verbal). Users generally used more verbal clues than visual clues in searches

- Abstract
- An individual's perception of structure in space is a crucial aspect of navigation. Reports sample results from an ongoing series of studies into how people learn to conceptualize the shape of information. 48 subjects from students and faculty at Indiana University, USA, ranging from novice to expert readers of academic journal literature in cognitive science participated. Results show that ability to sense where one is in information space, is a defining characteristic of expert information users, and that novice or inexperienced users are likely to need help acquiring this sense of location

- Abstract
- At Indiana, we are currentlxy investigating several aspects of electronic document usage that relate to the organization of information in digital environments. This work is collectively referred to under the heading: the perception of ahpe in information. The aim of this research is to identify aspects of presentation that affords users with a sense of location and order in electronic space, and to transfer these findings to developers of digital library applications. As well as empirical research, SLIS is involved in the development of a number of practical projects involving the campus libraries utilising sociotechnical approaches to design, but it is the research component of our efforts that will be emphasized here

- Abstract
- Proposes the artifact as theory perspective which drwas together models of scientific practice and design behaviour and in so doing, offers the view of any information technology system as a conjecture on the part of the design team of human and organizational requirements to be met. By adopting this perspective, information system design can be seen as an ill structured problem best tacked by user centred theories and methods. Outlines this perspective, emphasizing the need for convergence of views at the outset of design, and demonstrating the advantages it offers to both the theory and practice of technology design and the fields of information science
