Presentation
In our project, we investigate the scientific validity of a specific self-built Adaptive Learning Tool in the field of dynamic geometry with a particular focus on the individual learning pathways of a highly diverse student population. 164 children of Luxembourg elementary schools, aged between 10 and 13 years, acted as test-group and explored elem...
Article
The Treignac water is a natural mineral water containing mainly orthosilicic acid. On inert substrates, it forms a silica film with fractal structures which cannot be reproduced in laboratory-reconstituted water. These structures form by condensation of orthosilicic acid monomers, following the Witten–Sander model of diffusion-limited aggregation....
Conference Paper
To allow researchers explore the use of active tangibles in different tabletop scenarios, affordable and easy-to-use rapid prototyping tools are needed. This paper presents the design and implementation of active tangibles based on a microcontroller-based development platform called Kniwwelino. They are wirelessly connected via WiFi and can be prog...

Human–robot interaction is a well-studied research field today; robots vary from tele-operators and avatars to robots with social characteristics. In this review paper, first we present related work on tele-operation, mobile robotic telepresence, and social robots. Then, we focus on the role of gestures and body language in robotics, and more preci...
Chapter
Competency self-assessment for Performance Appraisal is receiving increasing attention from both researchers and practitioners. Nevertheless, the accuracy and supposed legitimacy of this type of assessment is still an issue. In the context of an industrial use case, we aim to develop and validate a computer-based competency self-assessment technolo...
Chapter
The construct to assess collaborative complex problem solving has two dimensions: the collaboration and the complex problem solving construct. Both have been defined in the past in the literature, but unfortunately no common model exists. In addition, current assessments lack of authentic tasks which enforce both face-two-face collaboration while s...

Collaborative problem solving is a skill that has become very important in our everyday lives and is constantly gaining attention in educational settings. In this paper, we present COPSE: a novel and unique software framework for instantiating Microworlds as collaborative problem solving activities on tangible tabletop interfaces. The framework pro...
Conference Paper
Full-text available
Currently designed Tangible User Interfaces (TUIs) propose both iconic and symbolic tangible objects (TO). Since iconic TOs should enable to interact more naturally like in the real world and, hypothetically, require less learning time than symbolic TOs, some questions arise: Why do symbolic TOs exist? When to use iconic or symbolic representation...
Chapter
Full-text available
Complex problem solving (CPS) is now established as a key aspect of today’s educational curricula and a central competence for international assessment frameworks. It has become clear that the educational context – particularly among general school-age students – places particular demands on the instruments used to assess CPS, such as computer-base...
Conference Paper
The tangible tabletop has been exploited in many different application domains as one of the most popular setups of Tangible User Interfaces. Proposed interaction techniques are based on, for instance, direct manipulation, dual hand input, or physical actuation. This paper reports on the design and implementation of a new interaction technique to s...
Conference Paper
In this paper, we describe a new software framework for tangible tabletop interfaces: TULIP. The framework uses an abstraction layer to receive information from computer vision frameworks, such as reacTIVision, and a widget model based on MCRit to enable rapid application development. TULIP applies Software Engineering principles such as Separation...

Article
The search of molecular structures inside a large database of chemical compounds is a critical step for many computer programs used in several domains of chemistry. During the last years, the size of many chemical databases has dramatically increased, hence in the meantime, search engines needed to be more and more powerful. The speed and the effic...

The assessment of higher order thinking skills should measure knowledge and procedure as well as attitudes and dispositions. It can be considered as multidimensional regarding the cognitive processes involved in solving, for instance, a complex problem. This paper reports on two empirical studies in which a so called tangible user interface (TUI) w...

In this paper, we present an approach for high stake decision making based on the processing of uncontrolled knowledge originated from e-communities. Knowledge bases fed by such communities can provide a very rich source for a diagnosis or decision-support systems. However, they inherently bear inherent problems due in particular to knowledge heter...
Conference Paper
The main purpose of this paper is to present a new approach for High-Stake Decision Support Systems. We introduce the challenge of the exploitation of heterogeneous community-based knowledge for decision-aid in critical situations. Knowledge shared in e-communities can be very rich, but is also inherently chaotic and questionable. Such uncontrolled...

Purpose – By providing interoperability users can be supported in sharing and reusing vocabularies and knowledge. Ontology alignment plays an important role in the context of semantic interoperability. Usually ontology alignment tools generate results that are difficult to understand or assess. In order to enable users to check and improve alignmen...

The ability of a system to interoperate with another is a multi-dimensional concern which must be considered simultaneously from different perspectives and covering all the concerns relevant for different stakeholders. In this paper, we present a model of interoperability for service-based inter-enterprise computing environments which is based on t...
Conference Paper
Full-text available
Though ontologies are widely used to solve some specific interoperability problems, there is no specific ontology defining what interoperability actually is, independently from any domain. In this paper, we propose and discuss a first version of such an ontology, namely the OoI (Ontology of Interoperability), which we formalized using the Ontology...

Today building Rich Internet Application (RIAs) still requires programmer's skills. The rare open frame- works which allow non-technical users to design rich content education modules are quite limited in terms of presentation and certainly hinder the creativity. EXULIS is a free, open-source cross-platform application that is able to display rich...

This paper aims at proposing a global view of the interoperability problem, independently of any domain. We first describe explicitly the problem, and the context in which it appears. We then suggest a general structure to handle the possible solutions. Finally, we propose some possible application of our model.
Conference Paper
Full-text available
Interoperability usually refers to software system communication. Although there is no widely accepted definition, and therefore no common understanding of the context, there are multiple solutions (protocols, architectures, components) that promise to solve integration issues. The INTEROP network of excellence aims at proposing a large view of int...
