• Originally background in computer graphics & computer graphics & interactive visualizationinteractive visualization
• Using the VRS scenegraph system for developing VR and desktop applicationsVR and desktop applications
• Dealing with different presentation devicesdifferent presentation devices and user interfaces
Demonstrations need to be device independentdevice independent
Problems arising when using VR-Systems
1.1. InstrumentationInstrumentation of the user
2.2. Cognitive overloadCognitive overload when performing 3D interactions
3.3. Lack of standardizationLack of standardization
