- KonferenzbeitragTowards a Generic Adaptive System applicable for Web-based Learning Management Environments(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Gütl, Christian; Mödritscher, FelixOne main objective of the AdeLE research project is the research and implementation of an enhanced, flexible and Web-based adaptive e-learning system by the application of finegrained profiling and modeling information using multimodal sensor data in real time. Based on our knowledge about a wide range of existing learning management systems (LMS), we have decided to develop an approach to connect and control existing LMSs in order to extend them with adaptability or adaptivity. Backed on our experiences of the first fully functional implementation of the AdeLE system, we introduce our approach towards a generic adaptive system applicable for Web-based learning management environments in this paper.
- 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.
- KonferenzbeitragUsing Action Analysis in ActiveMath to Estimate Student Motivation(13. GI-Workshop "Adapitivität und Benutzermodellierung in interaktiven Softwaresystemen", 2005) Muehlenbrock, Martin; Scheuer, OliverRecently, there is a growing interest in the automatic analysis of learner interaction data with web-based learning environments. The approach presented in this paper aims at helping to establish a basis for the automatic analysis of interaction data by developing a data logging and analysis system based on a standard data base server and standard machine learning techniques. The analysis system has been connected to a web-based interactive learning environment for mathematics teaching, but is designed to allow for interfacing also to other web based learning environments. The system has been used to correlate student logs from an educational technologies course with a motivation assessment.
- 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.
- 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.
- 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.
- 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.
