A b s t r a c t This paper discusses experiences and lessons learned from the design of an open hypermedia system, one that integrates applications and data not " owned " by the hypermedia. The Dexter Hypertext Reference Model [8] was used as the basis for the design. Though our experiences were generally positive, we found the model constraining in certain(More)
This paper discusses how to augment the WWW with a Dexter-based hypermedia service that provides anchors, links and composites as objects stored external to the Web pages. The hypermedia objects are stored in an object-oriented database that is accessible on the Web via an ordinary URL. The Dexter-based hypermedia service is based on the Devise Hypermedia(More)
This paper discusses issues for the design of a Dexter-based cooperative hypermedia architecture and a specific system, DeVise Hypermedia (DHM), developed from this architecture. The Dexter Hypertext Reference Model [9, 10] was used as the basis for designing the architecture. The Dexter model provides a solid foundation for designing a general hypermedia(More)
Early hypertext systems were monolithic and closed, but newer systems tend to be open, distributed, and support collaboration. While this development has resulted in increased openness and flexibility, integrating or adapting various different tools, such as content editors, viewers or even other link servers has remained a tedious task. Many developers(More)
In most development projects, descriptions and prototypes are developed by system designers on their own utilizing users as suppliers of information on the use domain. In contrast, we are proposing a cooperative prototyping approach where users are involved actively and creatively in design and evaluation of early developed prototypes. This paper will(More)
This paper presents a Guided tour system for the WWW, called Ariadne, which implements the ideas of trails and guided tours, originating from the hypertext field. Ariadne appears as a Java applet to the user and it stores guided tours in a database format separated from the WWW documents included in the tour. The main advantages of the system compared to(More)
This paper introduces a novel kinesthetic interaction technique for interactive floors. The interaction techniques utilize vision-based limb tracking on an interactive floor – a 12 m 2 glass surface with bottom projection. The kinesthetic interaction technique has been developed for an interactive floor implemented in a school square. The paper discusses(More)
The Dexter Hypertext Reference model is well suited to modelling anchor-based hypermedia systems and static hypermedia structures. But it is less clear that Dexter is adequate for systems whose linking is based on embedded references like the World Wide Web (WWW), nor for modelling the dynamic aspects of contemporary hypermedia systems like DHM and(More)
