    Supporting Distributed Learning through Immersive Learning Environments

    No full text
    In this paper, we describe a teaching scenario using a virtual environment (known also in the context of the ‘metaverse’). This is motivated by the challenges that arise during the pandemic. More and more teaching scenarios are transferred to online learning settings, which allow learning at any time and at any time. One of the possibilities are virtual 3D environment. These allow more intensive immersion than for example video conferences. Furthermore, they offer new didactic concepts, for example, for group activities. The benefit of using virtual 3D environments we demonstrate by a concrete learning scenario: the simulation of robot programming. A further advantage when using virtual 3D environments are personal assistants (conversational/ pedagogical agents), for example, to the ease the work load borne by teachers; meanwhile, this works well also with natural language due to advantage stage of artificial intelligence implementations

    Flexible queries in distributed structured and semistructured documents

    No full text
    The goal of the thesis is to solve the task of defining a flexible query language for distributed structured and semistructured data and to implement this language. For example, data can be represented as HTML files in the file system, whereby an XML document contains metadata about these files. Hence, these two data sources have to be merged appropriately. In order to satisfy the needs of the heterogeneous group of users, a flexible adaptable query language is required. Therefore a query model is developed which serves as a basis for an abstract syntax for query languages; this abstract syntax can be translated in concrete textual as well as graphical query languages. An implementation of the ideas proposed in the thesis is done in the area of virtual courses, especially in the project ”Virtual University of Applied Sciences”
