Elements Of Hypermedia Design Techniques For Navigation Visualization In Cyberspace

The hypermedia authoring process has been vividly described in a special issue of the Economist as a combination of writing a book, a play, a film, and a radio or television show: A hypermedia document combines all these elements and adds some of its own. The author' s first job is to structure and explain all of the infor mation. The author then must distill the information into brief, descriptive nodes. Each node has to contain a Iist of the ingredients, and instructions on how the ingredients are mixed together to the greatest advantage. The structure of the material provided is translated into an architectural metaphor of some kind; much of the designer' s work is the creation of this imaginary space. Then, the designers must chart the details of what to animate, what to film, who to inter view, and how to arrange the information in the space tobe built [Eco95a]. This book presents guidelines, tools, and techniques for prospective authors such that they can design better hypermedia documents and applications. lt surveys the different techniques used to organize, search, and structure infor mation in a large information system. It then describes the algorithms used to locate, reorganize, and link data to enable navigation and retrieval. It Iooks in detail at the creation and presentation of certain types of visual information, namely algorithm animations. It introduces new mechanisms for editing audio and video data streams.

A surprisingly dry guide intending to provide prospective hypermedia authors with the tools and techniques to design documents and applications. Given the creative content of the subject matter, Gloor (informations systems specialist, Coopers and Lybrand) does an incredible job at making it lifeless and colorless while surveying techniques to organize, search, and structure information, as well as describing the algorithms used to locate, reorganize, and link data for navigation. He particularly focuses on algorithm animation, new mechanisms for editing audio and video data streams, and their application on (ho hum) conference proceedings. Includes lots of flow charts.

This book will be a valuable addition to the growing body of literature on cyberspace and what it means for the future.

This is the 12th volume in a series on information modelling and knowledge bases. The topics of the articles cover a wide variety of themes in the domain of information modelling, design and specification of information systems and knowledge bases, ranging from foundations and theories to systems construction and application studies. The contributions in this volume represent the following major themes: models in intelligent activity; concept modelling and conceptual modelling; conceptual modelling and information requirements specification; collections of concepts, knowledge base design, and database design; human-computer interaction and modelling; software engineering and modelling; and applications.

During the last three decades geosciences and geo-engineering were influenced by two essential scenarios: First, the technological progress has changed completely the observational and measurement techniques. Modern high speed computers and satellite based techniques are entering more and more all geodisciplines. Second, there is a growing public concern about the future of our planet, its climate, its environment, and about an expected shortage of natural resources. Obviously, both aspects, viz. efficient strategies of protection against threats of a changing Earth and the exceptional situation of getting terrestrial, airborne as well as spaceborne data of better and better quality explain the strong need of new mathematical structures, tools, and methods. Mathematics concerned with geoscientific problems, i.e., Geomathematics, is becoming increasingly important. The ‘Handbook Geomathematics’ as a central reference work in this area comprises the following scientific fields: (I) observational and measurement key technologies (II) modelling of the system Earth (geosphere, cryosphere, hydrosphere, atmosphere, biosphere) (III) analytic, algebraic, and operator-theoretic methods (IV) statistical and stochastic methods (V) computational and numerical analysis methods (VI) historical background and future perspectives.

This book addresses the various aspects of computational support systems for learners nowadays. It highlights in particular those learning aspects that rely heavily upon one's imagination of knowledge and new ideas. The question is how learners may become more effective through the use of highly graphical computer systems that now conquer almost every desk. As an extrapolation of the constructionistic paradigm, learning is seen here as a process of conceptual design. Witnessing the prudent introduction of CADD software (Computer Aided Drafting and Design) it is obvious that users are generally scrupulous to accept the computer in the ideational stages of design. This book presents both existing conceptual techniques and those estimated to arrive in the few coming years.

This book describes the research of the authors over more than a decade on an end-to-end methodology for the design and development of Web Information Systems (WIS). It covers syntactics, semantics and pragmatics of WIS, introduces sophisticated concepts for conceptual modelling, provides integrated foundations for all these concepts and integrates them into the co-design method for systematic WIS development. WIS, i.e. data-intensive information systems that are realized in a way that arbitrary users can access them via web browsers, constitute a prominent class of information systems, for which acceptance by its a priori unknown users in varying contexts with respect to the presented content, the ease of functionality provided and the attraction of the layout adds novel challenges for modelling, design and development. This book is structured into four parts. Part I, Web Information Systems – General Aspects, gives a general introduction to WIS describing the challenges for their development, and provides a characterization by six decisive aspects: intention, usage, content, functionality, context and presentation. Part II, High-Level WIS Design – Strategic Analysis and Usage Modelling with Storyboarding, introduces methods for high-level design of WIS covering strategic aspects and the storyboarding method, which is discussed from syntactic, semantic and pragmatic perspectives. Part III, Conceptual WIS Design – Rigorous Modelling of Web Information Systems and their Layout with Web Interaction Types and Screenography, continues with conceptual design of WIS including layout and playout. This introduces the decisive web interaction types, the screenography method and adaptation aspects. The final Part IV, Rationale of the Co-Design Methodology and Systematic Development of Web Information Systems, describes the co-design method for WIS development and its application for the systematic engineering of systems. The book addresses the research community, and at the same time can be used for education of graduate students and as methodological support for professional WIS developers. For the WIS research community it provides methods for WIS modelling on all levels of abstraction including theoretical foundations and inference mechanisms as well as a sophisticated end-to-end methodology for systematic WIS engineering from requirements elicitation over conceptual modelling to aspects of implementation, layout and playout. For students and professional developers the book can be used as a whole for educational courses on WIS design and development, as well as for more specific courses on conceptual modelling of WIS, WIS foundations and reasoning, co-design and WIS engineering or WIS layout and playout development.

This book integrates the science of spatial cognition and the science of team cognition to explore the social, psychological, and behavioral phenomenon of spatial cognition as it occurs in human collectives such as dyads and work teams. It represents the culmination of a process of outlining and defining a growing field of research termed Collective Spatial Cognition. It engages contributions from an international and multi-disciplinary community of scholars, who have collaborated to provide a foundation for knowledge discovery regarding how groups of people of varying size acquire information and solve problems involving spatiality as a key component, leading to action that incorporates the spatial information and problem-solving collectively achieved. The collectives under study can be as small as dyads (teams of two) to large teams-of-teams who are working alongside each other to complete a mutual goal. The book lays the foundation for multi- and interdisciplinary work regarding Collective Spatial Cognition in the years to come, and this book documents that foundation. This book will be of interest to those researching spatial, behavioural, cognitive, and information sciences in the fields of human geography, sociology, psychology, and computer science.
