    User-centred design of flexible hypermedia for a mobile guide: Reflections on the hyperaudio experience

    Get PDF
    A user-centred design approach involves end-users from the very beginning. Considering users at the early stages compels designers to think in terms of utility and usability and helps develop the system on what is actually needed. This paper discusses the case of HyperAudio, a context-sensitive adaptive and mobile guide to museums developed in the late 90s. User requirements were collected via a survey to understand visitors’ profiles and visit styles in Natural Science museums. The knowledge acquired supported the specification of system requirements, helping defining user model, data structure and adaptive behaviour of the system. User requirements guided the design decisions on what could be implemented by using simple adaptable triggers and what instead needed more sophisticated adaptive techniques, a fundamental choice when all the computation must be done on a PDA. Graphical and interactive environments for developing and testing complex adaptive systems are discussed as a further step towards an iterative design that considers the user interaction a central point. The paper discusses how such an environment allows designers and developers to experiment with different system’s behaviours and to widely test it under realistic conditions by simulation of the actual context evolving over time. The understanding gained in HyperAudio is then considered in the perspective of the developments that followed that first experience: our findings seem still valid despite the passed time

    The CoAKTinG project aims to advance the state of the art in collaborative mediated spaces for the Semantic Grid. This paper presents an overview of the hypertext and knowledge based tools which have been deployed to augment existing collaborative environments, and the ontology which is used to exchange structure, promote enhanced process tracking, and aid navigation of resources before, after, and while a collaboration occurs. While the primary focus of the project has been supporting e-Science, this paper also explores the similarities and application of CoAKTinG technologies as part of a human-centred design approach to e-Learning

    Teaching new media composition studies in a lifelong learning context

    Governmental proposals for lifelong learning, and the role of Information and Learning Technologies/Information Communication Technologies (ILT/ICT) in this, idealistically proclaim that ILT/ICT empowers learners. A number of important governmental funding initiatives have recently been extended to the development of ILT in further education, which provides a particularly appropriate environment for lifelong learning. Yet little emphasis is given to more problematic research findings that students may be ‘disarmed’ in the process of learning to use technology. In the current global shift towards new forms of multimedia literacy, it is important to recognize human diversity by carrying out research focusing on the actual problems students face in adapting to Web‐based technology as a new authoring medium. A case study into multimedia creative composition carried out with FE students in 1996–9 found that students tend to experience a problematic but potentially useful period of ‘creative mess’ when authoring in multimedia, and that ‘scaffolding’ strategies can be useful in overcoming this. Such strategies can empower students to derive benefits from multimedia composition if close attention is given to the setting up of the learning environment: a teachers’ model for supporting novice hypermedia authors in further education is proposed, to assist teachers to understand and support the learning processes students may undergo in dynamic composition using new media technology

    What is the problem to which interactive multimedia is the solution?

    This is something of an unusual paper. It serves as both the reason for and the result of a small number of leading academics in the field, coming together to focus on the question that serves as the title to this paper: What is the problem to which interactive multimedia is the solution? Each of the authors addresses this question from their own viewpoint, offering informed insights into the development, implementation and evaluation of multimedia. The result of their collective work was also the focus of a Western Australian Institute of Educational Research seminar, convened at Edith Cowan University on 18 October, 1994. The question posed is deliberately rhetorical - it is asked to allow those represented here to consider what they think are the significant issues in the fast-growing field of multimedia. More directly, the question is also asked here because nobody else has considered it worth asking: for many multimedia is done because it is technically possible, not because it offers anything that is of value or provides the solution to a particular problem. The question, then, is answered in various ways by each of the authors involved and each, in their own way, consider a range of fundamental issues concerning the nature, place and use of multimedia - both in education and in society generally. By way of an introduction, the following provides a unifying context for the various contributions made here

    Kartografski informacijski sustav \u27\u27ÖROK Atlas Online\u27\u27 – AIS Austrija kao komunikacijski portal temeljnih geopodataka o Austriji

    \u27\u27ÖROK Atlas Online\u27\u27 – Atlas Information System Austria (AIS-Austria) – is a research and development project of the Austrian Conference on Spatial Planning (ÖROK) for the construction of a prototype for an interactive, multi-media thematic atlas in cooperation with the Department of Geography and Regional Sciences (IFGR) – University Vienna, the Department of Geoinformation and Cartography (IGK) – University of Technology Vienna and the Austrian Institute of Regional Planning (ÖIR) – Information Services GmbH (I: D). The project started in September 2004. The project duration is 1,5 years. In the prototype of the web atlas, on the basis of the topographical basic geo-data, predefined and prepared for several scales (the basic scale for Austria is 1:1,000.000), thematic contents will be visualized and made accessible over the interactive map based graphical user interface as a communication portal. AIS-Austria is a hybrid system which should be able to ensure also the printed map in a high graphic resolution (the dual atlas principle). The user navigation and system functionalities, which provide the geo-communication, will be presented.\u27\u27ÖROK Atlas Online\u27\u27 – Atlas Information System Austria (AIS-Austria) – je znanstveno-tehnološki projekt Austrijske konferencije za prostorno planiranje (Österreichische Raumordnungskonferenz). U projektu je razrađen prototip interaktivnog, multimedijskog tematskog atlasa na čijoj realizaciji sudjeluju Institut za geografiju i regionalne znanosti Sveučilišta u Beču, Institut za geoinformacije i kartografiju Tehničkog sveučilišta u Beču i Austrijski institut za regionalno planiranje. Projekt je započeo u rujnu 2004. i trajat će 1,5 godinu. U prototipu atlasa bit će realiziran pristup temeljnim topografskim geopodacima, koji su kartografski unaprijed pripremljeni u nekoliko osnovnih mjerila. Nadalje, vizualizacija i interaktivni pristup tematskim podacima bit će dostupan preko korisničkog sučelja kao komunikacijskog portala, čiji je temelj kartografski prikaz (topografija ili već vizualizirana tematika). AIS-Austria je zamišljen kao hibridni informacijski sustav, koji prema želji korisniku daje mogućnost izdavanja sadržaja po vlastitom izboru u vidu papirnate karte visoke kvalitete (dualni princip atlasa). U članku će biti prikazane mogućnosti navigacije kao i funkcionalnost sustava, što podržava geokomunikaciju

    Personalization in cultural heritage: the road travelled and the one ahead

    Get PDF
    Over the last 20 years, cultural heritage has been a favored domain for personalization research. For years, researchers have experimented with the cutting edge technology of the day; now, with the convergence of internet and wireless technology, and the increasing adoption of the Web as a platform for the publication of information, the visitor is able to exploit cultural heritage material before, during and after the visit, having different goals and requirements in each phase. However, cultural heritage sites have a huge amount of information to present, which must be filtered and personalized in order to enable the individual user to easily access it. Personalization of cultural heritage information requires a system that is able to model the user (e.g., interest, knowledge and other personal characteristics), as well as contextual aspects, select the most appropriate content, and deliver it in the most suitable way. It should be noted that achieving this result is extremely challenging in the case of first-time users, such as tourists who visit a cultural heritage site for the first time (and maybe the only time in their life). In addition, as tourism is a social activity, adapting to the individual is not enough because groups and communities have to be modeled and supported as well, taking into account their mutual interests, previous mutual experience, and requirements. How to model and represent the user(s) and the context of the visit and how to reason with regard to the information that is available are the challenges faced by researchers in personalization of cultural heritage. Notwithstanding the effort invested so far, a definite solution is far from being reached, mainly because new technology and new aspects of personalization are constantly being introduced. This article surveys the research in this area. Starting from the earlier systems, which presented cultural heritage information in kiosks, it summarizes the evolution of personalization techniques in museum web sites, virtual collections and mobile guides, until recent extension of cultural heritage toward the semantic and social web. The paper concludes with current challenges and points out areas where future research is needed

    Sensemaking on the Pragmatic Web: A Hypermedia Discourse Perspective

    Get PDF
    The complexity of the dilemmas we face on an organizational, societal and global scale forces us into sensemaking activity. We need tools for expressing and contesting perspectives flexible enough for real time use in meetings, structured enough to help manage longer term memory, and powerful enough to filter the complexity of extended deliberation and debate on an organizational or global scale. This has been the motivation for a programme of basic and applied action research into Hypermedia Discourse, which draws on research in hypertext, information visualization, argumentation, modelling, and meeting facilitation. This paper proposes that this strand of work shares a key principle behind the Pragmatic Web concept, namely, the need to take seriously diverse perspectives and the processes of meaning negotiation. Moreover, it is argued that the hypermedia discourse tools described instantiate this principle in practical tools which permit end-user control over modelling approaches in the absence of consensus
