- 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.
- 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.
- KonferenzbeitragSeamless Combination of Shared and Personalized Information Presentation to Groups of Visitors in Active Museums – Research Agenda(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Baus, Jörg; Krüger, Antonio; Kuflik, TsviThe goal of the proposed research is to enhance group experiences in a museum by: (1) intelligent distribution of information across several devices, allowing members of a group to follow a public presentation while their personal interests are addressed through individual annotations on a private device, and (2) navigation support of the whole group, by finding a route through the museum that maximizes the interests of all group members and helps to mutually explore and uncover most of the relevant topics related to a cultural heritage site.
- KonferenzbeitragPotentials and Challenges of Context-Awareness for Learning Solutions(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Schmidt, AndreasCurrent e-learning systems fail to take into account the situation of the learner appropriately although there is a big potential for improving those systems. This paper tries to summarize the potentials and highlight the key challenges of context-aware learning systems. It also presents some steps towards mastering the challenges.
- 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.
- 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.
- 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.
- KonferenzbeitragTowards a Service Based Architecture for Assessment(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Cheniti-Belcadhi, Lilia; Henze, Nicola; Braham, RafikIn this paper we propose the outline of a service based architecture for bringing assessment techniques to open e-learning environments. We first describe a use case scenario for a generic assessment framework offering personalized assessment generation and then present its basic architecture as part of the Personal Reader Frame- work. The generic assessment framework enables the search for the appropriate assessment resources after checking the learner’s last saved performances and specific needs (e.g. language preferences, device requirements). In our assessment framework personalization functionalities are available as web services. The communication between these services is based on the Semantic Web technologies and does not need a centralized control. The assessment functionalities are defined in a separate Web service, which a user can subscribe/ un-subscribe as s/he likes.
- KonferenzbeitragThe Virtual Bookshelf Approach(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Broberg, Anders; Hägglund, UlrikaThe amount of information that people have to handle in their everyday life has increased and more is asked of their cognitive ability to select and assimilate the information that is important to them. One way to facilitate the cognitive work is to match information objects with each other and select/filter the ones that are relevant. To do this selection objects must be represented in such a way that comparison is possible. This paper presents the virtual bookshelf approach, which means that the user collects information that he/she finds interesting, and from this collection an information space is created aimed to be used for comparing and deciding the relevancy of new objects.
