A General Framework for Digital Game-Based Training Systems

This dissertation introduces a general framework for developing digital game-based training systems. The framework addresses all aspects of education. In that sense, it involves both teacher and student as game players. A visual review log supports teacher-student-communication. Based on the general framework, a novel digital game-based training system for crime scene investigation training called OpenCrimeScene has been developed and implemented.Diese Dissertation führt ein allgemeines Architekturmodell für die Entwicklung von computerspielbasierten Trainingssystemen ein. Das Architekturmodell spricht alle Aspekte der Ausbildung an. In diesem Sinne bezieht es Lehrer und Schüler als Spieler ein. Ein grafisches Bewertungsprotokoll unterstützt die Lehrer-Schüler-Kommunikation. Basierend auf dem allgemeinen Architekturmodell wurde ein neues computerspielbasiertes Trainingssystem zur Tatortsicherung entwickelt und implementiert

vSLRcam – taking pictures in virtual environments

Our work presents a virtual single lens reflection camera (vSLRcam) application which is employed in a virtual training environment for crime scene investigation. vSLRcam’s back-end is a GPU based simulation of a realistic camera model taking into account SLR camera properties like apperture, shutter speed, lens, etc., as well as their interdependencies. Thus, we can obtain realistic lens effects like motion blur or depth of field in real-time. The application user interface allows for parameterizing the inidividual camera attributes to achieve those effects and, as a result, to take realistic pictures of the scene. The resulting images come very close to real world photographs with equal parameter values. Our main contributions are a common framework for the SLR camera attributes and the simulation of their interdependecies in a single application which is capable of rendering photographic lens effects in real-time
