Hypertext development using a model-based approach

Hypertext development is still, for the most part, at the ‘handcrafting’ level, where each hypertext document must be hand-designed. We present a compiler which takes hyperdocuments designed using a model-based approach and generates stacks executable in Hyper Card. This compiler is implemented in standard SQL over a relational database representation of a hyperdocument designed using the hypermedia design model (HDM). The compiling approach, even though illustrated with HDM, can be used with any ‘structured’ design methodology.     

A model for integrating multimedia information around 3D graphics hierarchies

We present a model for organizing multimedia information especially suitable for applications with three-dimensional content. The model relies on the hierarchical nature of 3D objects, which are utilized as centralizing structure to give coherence to the organization and access of all other medium types. Techniques have been developed to facilitate the manipulation of all medium types through a consistent user interace paradigm. The modeling of space and time constraints as applied to the animation of graphical objects and their synchronization with video has also been explored. Two industrial training applications have been developed to demonstrate the usability of the system.     

A behavioral analysis and verification approach to pattern-based design composition

Integrating software components to produce large-scale software systems is an effective way to reuse experience and reduce cost. However, unexpected interactions among components when integrated into software systems are often the cause of failures. Discovering these composition errors early in the development process could lower the cost and effort in fixing them. This paper introduces a rigorous analysis approach to software design composition based on automated verification techniques. We show how to represent, instantiate and integrate design components, and how to find design composition errors using model checking techniques. We illustrate our approach with a Web-based hypermedia case study.

Evaluation of a hypermedia document as a learning tool

This paper describes a classroom‐based experimental evaluation of an electronic history 'book' presented in a hypermedia environment. It was compared with a paper‐based version of the same material. Observations of children's activities and interactions revealed that they had few problems using the hypermedia document as an information source and also rated it more positively, in terms of ease of use, than those children using the paper‐based version. However, no significant differences were found between the two groups in the number of questions children completed and answered correctly, their interest in the material, and task difficulty. The implications of these findings and the role of evaluation in determining the educational value of computer‐based activities are discussed.
