- KonferenzbeitragAdaptation to Motivational States in Educational Systems(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Weibelzahl, Stephan; Kelly, DeclanMost current Adaptive Educational Systems model cognitive characteristics of students such as learning goals, knowledge and preferences. However, motivation obviously plays a key role in education. This paper reviews the state-of-the- art regarding adaptation to motivation. Open research issues that need to be addressed are identified.
- KonferenzbeitragAdaptive features of a hypermedia system using bookmark per Web page(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Jung, Hyosook; Park, SeongbinIn this paper, we present a technique called bookmark per Web page by which users can build a new link structure in a hypermedia. It allows users to create their own links for Web pages. Our aim is to provide an adaptive hypermedia with additional adaptive features by considering properties which the author of the hyperspace did not provide when the hyperspace was designed. In addition, a general hypermedia that does not have adaptive features can support personalized views of hyperdocuments using this technique. We expect that the bookmark per Web page can enhance information accessibility and reduce navigation disorientation and cognitive overload. We implemented our technique by modifying AHA![De Bra et al., 2003] which is an open source adaptive hypermedia system. We developed Java servlets and included them in the adaptation engine of AHA!. We added a link at- tribute for each concept at the user profile and assigned URL addresses of new links for its values.
- KonferenzbeitragCharacterizations of User Web Revisit Behavior(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Herder, EelcoIn this article we update and extend on earlier long-term studies on user’s page revisit behavior. Revisits are very common in web navigation, but not as predominant as reported in earlier studies. Backtracking is the most common type of page revisitation and is both used for finding new information and relocating information visited before. Search engines are mainly used for finding new information and users frequently backtrack to result pages. Visits to pages already visited in earlier sessions tend to occur in chunks, but it is not straightforward to create a list of most likely pages that will be revisited. We conclude with a short discussion on design implications for user-adaptive revisitation support.
- KonferenzbeitragConfiguration and Introspection of Situated User Support(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Baldes, Stephan; Kröner, Alexander; Bauer, MathiasUser support which takes into account the user‘s current context is a key issue of ambient intelligence applications. In this contribution we address the question of how a user may configure and keep control of situated user support. Background of our work is a system, which creates an augmented, personal memory from events perceived in an instrumented environment. We show how the user may –assisted by the system– perform a collaborative introspection of this memory in order to learn about and to exploit past events for user support. In particular we discuss methods for evaluating events and for acquiring proactively feedback in order to improve the quality of a binding between situations and system services.
- KonferenzbeitragCourse Generation Based on HTN Planning(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Ullrich, CarstenA course generator automatically assembles learning objects retrieved from one or several repositories to a greater unit. Different frameworks for course generation exists, but only a few allow the representation of sophisticated pedagogical knowledge. In this paper, we describe course generation based on pedagogical tasks and methods, formalized in a hierarchical task network (HTN) planner. We describe the moderate constructivist learning strategy we implemented in this framework, problems that arouse from using HTN planning and their solutions. A first evaluation supports the practical value of our approach.
- KonferenzbeitragEnabling Natural Interaction by Approaching Objects(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Lorenz, Andreas; Zimmermann, Andreas; Eisenhauer, MarkusThis paper introduces the research issues to make a major step towards natural human interaction with mobile multimodal systems. Thereby, we aim at combining explicit and implicit interaction to blended multimodal interaction. Natural inter- action and the requirement to anticipate a mix of purposive behaviour and uncertainty requires rendering information in a way that is compatible with and aware of the situational context. In two application examples we illustrate our approaches of interaction by movement. As the basis for adaptive behaviour, this paper describes the conclusions drawn from tracking the mobile user in two environments: a museum and a maintenance setting. It also illuminates different aspects of this technology, such as accuracy and costs, and illustrates the results of our project using the specific technology.
- KonferenzbeitragEnhancing adaptive capabilities of an adaptive hypermedia system(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Jung, Hyosook; Park, SeongbinIn a complex hyperspace, people may experience the problems of disorientation and cognitive overload[Conklin, 1987] and to overcome these problems, adaptive hypermedia technologies provide personalized information to learners with different learning paces, abilities, interests, etc[De Bra et al., 1999]. However, it is difficult to predict complex situations that could arise during navigation in an adaptive hypermedia in advance. For example, users may want to extend the con- tents of an adaptive hypermedia when they find some information using a search engine. In this paper, we propose an approach by which adaptive capabilities of an exiting adaptive hypermedia such as adapting according to changes of a domain model or a user model can be enhanced.
- KonferenzbeitragEstimating User Affect and Focus of Attention from Physiological Signals in Life-Like Character Based Interaction Scenarios(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Prendinger, HelmutThis paper abstract highlights some of our recent research efforts in designing and evaluating life- like characters that are capable of entertaining affective and social communication with users. The key novelty of our approach is the use of human physiological information: first, as a method to evaluate the effect of life-like character behavior on a moment-to-moment basis, and second, as an input modality for a new generation of interface agents that we call ‘physiologically perceptive’ characters. By exploiting the stream of primarily involuntary human responses, such as biometric signals and eye movements, those characters are expected to respond to users’ affective and social needs in a truly sensitive, and hence effective, friendly, and beneficial way.
- KonferenzbeitragMigrating Characters Performing Explicit Physical Object References(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Kruppa, MichaelThe main goal of the work presented in this paper is to determine an optimal strategy for virtual characters performing judicious combinations of speech, gesture and motion in order to disambiguate references to objects in the physical environment. The work is located in the research area of mobile computing and deals with the combination of mobile and stationary devices.
- KonferenzbeitragMUSE: A Multidimensional Semantic Environment for Adaptive HypermediaSystems(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Carmagnola, Francesca; Cena, Federica; Gena, Cristina; Torre, IlariaThis paper proposes a semantic framework built on multidimensional ontological planes for the design of adaptive systems. The core of the framework is composed by three matrices whose different planes contain the ontological representation of different types of knowledge. On these planes we represent user features, her actions, context, device, content domain, adaptation goals and methods. The join between planes allows us to represent semantic rules for inferring new user features and to define adaptation strategies. We exploit OWL (Ontology Web Language) to rep- resent taxonomic knowledge and SWRL (Semantic Web Rule Language) for rules. The frame- work presents a new approach to build adaptive hypermedia systems that support interoperability.
