This work presents the design and the features of a flexible realtime 3D graphics engine aimed at the development of multimedia applications and collaborative virtual environments. The engine, called EnCIMA (Engine for Collaborative and Immersive Multimedia Applications), enables a fast development process of applications by providing a high level interface, which has been implemented using the...

In this paper, we propose three different ways of using IMS Learning Design to support online adaptive learning modules that include educational videogames. The first approach relies on IMS LD to support adaptation procedures where the educational games are considered as Learning Objects. These games can be included instead of traditional content to adapt the learning experience to the preferen...

The Workflow Management System AltaVista Works has been extended to be able to process workflows in a distributed, partly even parallel manner. Build-time data are replicated over all participating workflow servers. The distribution of workflow execution is based on migration. Instead of the usual, static pre-partitioning, highly dynamic management of distribution is applied.

The generalization of game-based Learning Objects as serious learning material requires their integration into pre-existing e-learning infrastructure (systems and courses) and the inclusion of gameplay-aware assessment procedures. In this paper, we propose an approach to the production and development of educational graphic adventure videogames that can be deployed as normal Learning Objects in...

This paper presents the design, implementation and evaluation of a dataflow system, including a dataflow programming model and a dataflow engine, for coarse-grained distributed data intensive applications. The dataflow programming model provides users with a transparent interface for application programming and execution management in a parallel and distributed computing environment. The datafl...

This paper discusses approaches for system integration in the context of eLearning applications, Learning Management Systems, and Campus Management Systems. Three current projects (elecTUM, CampusSource Engine Integration Platform, and e-Framework) are discussed. Finally a Service Oriented Architecture (SOA) for these integration tasks and an abstraction layer of Campus Management Systems is ou...
