TY - JOUR A1 - Jarz, Ewald T1 - Theoretical Aspects of Multimedia JF - Desidoc Bulletin of Information Technology N2 - This paper is an interdisciplinary synopsis about multimedia learning systems and mass information systems, and presents an action model for construction of these systems and the embedding of this model in an existing concept of system planning. First step in the paper is the containment and definition of the term ‘multimedia’ on the basis of general criterions of the human-machine-human communication. Result is a taxonomy to classify scientific research areas in this field. The second part follows an examination of different concepts of learning theories by means of a five dimensional raster. Output of this examination are two models fitting for computer based learning in general. The third part discusses information presentation and interaction possibilities at the human - machine - interface. Therefore a consistent raster is acquired, where psychological perception parameters and technical parameters of information presentations and interaction possibilities are examined. This results in the so-called storyboarding, which is the description of a process adapted from theater, film and TV for developing a multimedia script. The combination of learntheoretical concepts with the process of storyboarding of multimedia applications and the embedding in a system planning action model is described in the fourth part. The result of this last part shows a phase concept for system planning of multimedia learning systems and mass information systems.

Both during the evolution and application of multimedia technology, well-founded theoretical concepts are missing. The intention of this paper is to show categories of different information representations and interaction types and their strengths in representing contents. A classification of multimedia information and interaction types is given also as an overview of the problem fields of multimedia, especially in the field of learning theory. This classification is used to give some guidelines for using and combining multimedia contents in multimedia systems.

The case study has been used within three courses of business process engineering. It was compared to a case study based solely on text. 13 assumptions have been evaluated. The main conclusion is that the multimedia based case study is much more practice oriented than a text based case study. Also the solutions of the students, which did the multimedia based case study, have been of higher quality. But on the other hand the expectations of the students to a multimedia based system are hard to meet. Based on these experiences some hints in further developing of multimedia based case studies are formulated.

The result is the conclusion that the documentation process can be fully automated. It follows from this analysis that the automated documentation can “only” supply information for the ITIL configuration management, respectively for the CMDB.

Dazu wird in der Arbeit zunächst der Begriff Multimedia anhand von allgemeinen Kriterien der Mensch-Maschine-Mensch - Kommunikation eingegrenzt und definiert. Ergebnis ist eine Systematik zur Einordnung von wissenschaftlichen Forschungsgebieten in diesem Bereich. Im zweiten Schritt erfolgt eine Untersuchung lerntheoretischer Konzepte anhand eines fünfdimensionalen Rasters. Ergebnis sind zwei Modelle, die sich zur elektronisch unterstützten Wissensvermittlung im allgemeinen eignen. Im dritten Schritt erfolgt eine Auseinandersetzung mit Informationsdarstellungen und Interaktionsmöglichkeiten an der Mensch-Maschine-Schnittstelle. Dazu wird ein konsistentes Raster erarbeitet, anhand dessen wahrnehmungspsychologische und technische Parameter von Informationsdarstellungen und Interaktionsmöglichkeiten untersucht werden. Ergebnis ist die Beschreibung von einem aus der Theater-, Film- und Fernsehbranche adaptierten Prozeß zur Erstellung eines multimedialen Drehbuchs, dem Storyboard. Der vierte Schritt beschreibt die Kombination der lerntheoretischen Konzepte mit dem Prozeß des Storyboardings multimedialer Anwendungen und die Einbettung in ein systemplanerisches Vorgehen dazu. Ergebnis ist ein Phasenkonzept zur Systemplanung multimedialer Lern- und Masseninformationssysteme.
