The Button Strikes Back BIBA 5-17
  Wendy Hall
This paper explores what has happened to hypermedia since the advent of the World Wide Web. We currently live in a world where access to the internet is dominated by Web browsers and search engines. The concept of hypermedia linking is at best added value and at worst almost irrelevant to most Web sites. But everyone who uses the Web is aware of the concept implicitly and accepts with ease the idea of clicking on a button to follow a link to another page. Search engines are the dominant means of finding information, but everyone is aware of their limitations. This is all set to change as we move into a world of pervasive computing and start to access the internet through small, hand-held devices. Agent technology will become the dominant means of building distributed information management systems. The paper argues that hypermedia technology will become more important in this world, although most users will be unaware of what software technology they are using as they navigate through global information spaces via highly personalised and adaptive environments.
Trailblazing: trends in hypermedia BIBA 19-46
  Daniel Cunliffe
"I believe we shall advance in our mastery over the records we create, rendering them easier to consult by means which would now seem strange and bizarre to us" (Vannevar Bush, 1967)
   The period from the mid 1980s has seen significant growth in hypertext as a coherent research area and in its impact on the general public. Many issues are only becoming apparent as researchers attempt to meet the requirements for long term industrial strength hypermedia applications deployed in real world situations. The papers in Hypermedia and The New Review of Hypermedia and Multimedia present an abridged history of this period of rapid development in the subject. This paper attempts to provide a broad review of some of the contributions to knowledge and general trends that can be identified from among the many papers published.
Media Construction Formalism Specifying Abstractions for Multimedia Scenario Design BIBA 47-87
  Jocelyne Nanard; Marc Nanard; Peter King
Most of the current work on the temporal aspects of hypermedia is oriented towards implementation and rendering. Relatively little work has been directed towards the design of hypermedia artifacts, particularly artifacts comprising large sets of media items with rich sets of temporal relationships. We introduce the media construction formalism (MCF), a formalism permitting the design of media construction abstractions (MCA) for the specification of multimedia scenarios. MCF provides constructs that can be understood and manipulated by designers at different levels of granularity and detail. MCF relies on a temporal model similar to that of SMIL 2.0, but targets design issues. MCF supports abstraction and re-use at the artifact design level and uses the notion of design patterns and the metaphor of roles, players and actors, to provide generic design descriptions. MCF provides an integrated specification of spatial, temporal, and object behavior, including composition which may depend on run time events. MCF provides a designer-friendly environment, incorporating a visual representation of partial designs together with a special-purpose structured editor.
The Link vs. the Event: Activating and Deactivating Elements in Time-Based Hypermedia BIBA 89-109
  Lynda Hardman; Patrick Schmitz; Jacco van Ossenbruggen; Warner ten Kate; Lloyd Rutledge
Activation and deactivation of media items plays a fundamental role in the playing of multimedia and time-based hypermedia presentations. Activation and deactivation information thus has to be captured in an underlying document format. In this paper we show that a number of aspects of activation and deactivation information can be captured using both link structures and events in time-based hypermedia. In particular, we discuss how deactivation and activation can be specified, how the activations and deactivations can be initiated and potential (synchronization) relationships between the elements involved.
   We first introduce the notions of time-based scheduling and event-based scheduling and then present a short summary of linking. We discuss the similarities between event-based scheduling and linking. We describe a number of aspects of activation and deactivation that can be specified within a document. We then discuss how activation and deactivation information can be recorded in link structures and events.
Hybrid Narrative and Categorical Strategies for Interactive and Dynamic Video Presentation Generation BIBA 111-145
  Craig A. Lindley; Frank Nack
There are a number of different approaches for automatically selecting video clips from a video database and sequencing them into meaningful presentations for viewers. The video database represents a multidimensional video hyperspace, and the sequencing algorithms function as (interactive) dynamic linking and path generation techniques within this hyperspace. Sequencing has been based upon either a narrative or a categorical model of video form. Each of these forms has its respective advantages and disadvantages, and varying suitability for different applications. The two primary forms may also be combined into several hybrid forms, both at the same level and at different levels of the syntactic composition of video sequences, to provide more options for authoring interactive dynamic video productions. Narrative, categorical, and hybrid sequence generation strategies can be applied to a variety of media modalities, including the automated generation of behaviour within virtual environments and computer animations.
Navigable History: A Reader's View of Writer's Time BIBA 147-167
  Frank M., III Shipman; Haowei Hsieh
Collecting, analyzing, and sharing information via a hypertext results in the continuous modification of information content over a long period of time. Such tasks will benefit from users having access to this authoring process. The Visual Knowledge Builder (VKB), a spatial hypertext system designed to support collaborative knowledge building, includes navigable history to provide readers a view of the writer's time. VKB acts as a workspace for collecting, organizing, and interpreting information in a hierarchy of two-dimensional planes. During authoring, VKB records events in the hypertext's history and provides methods to access prior states of the hypertext. The reader may play forward or backward through the authoring process as well as search for a variety of authoring events on information objects. Users receive cues about the absolute and relative timelines of the information space through the presentation of information about specific events and their sequence. Examples of VKB's use include note taking, writing, organizing conferences, and sharing information in a research group. Analysis of VKB workspaces in these contexts indicates navigable history supports (1) learning and interpreting authors' work practices, (2) recognizing patterns of activity in the information space, and (3) disambiguating specific actions and content. Hypertexts that include an authoring history add a notion of constructive time for their readers.
Hypertext interactivity: From choice to participation BIBA 169-196
  Gene Golovchinsky; Catherine C. Marshall
Much of hypertext narrative relies on links to shape a reader's interaction with the text. But links may be too limited to express ambiguity, imprecision, and entropy, to allow appropriate control and access to information, or to admit new modes of participation short of full collaboration. We use an e-book form to explore the implications of freeform annotation-based interaction with hypertext narrative. Readers' marks on the text can be used to guide navigation, to create a persistent record of a reading, to enable fluid exploration and revisits, or to recombine textual elements as a means of creating a new narrative. In this paper, we describe how such an experimental capability was created with XLibris, a next generation e-book, using Forward Anywhere as the hypernarrative. We work through a scenario of interaction, and discuss the issues the work raises.
Mind the eye! On the relevance of composition in spatial organization BIBA 197-202
  Moritz Neumuller
This paper focuses on the relationship between semantics and aesthetics in spatial hypertext. The author departs from the observation that certain metaphors from the GUI world have a stronger effect on spatial hypertext than on other information systems. It is argued that the human desire to compose objects on a picture plane not only due to semantic, but also due to aesthetic principles, counteracts the construction of meaning. The author intends to encourage a discussion about the tension between finished presentational structures and working interpretive structures in spatial hypertext systems. The grounding of this discussion are art theory, psychology and other non-hypertext sources.
