1. VR as a Next-Generation User Interface?
Originally background in computer graphics & interactive visualization
Using the VRS scenegraph system for developing VR and desktop applications
Dealing with different presentation devices and user interfaces
 Demonstrations need to be device independent
Problems arising when using VR-Systems
Instrumentation of the user
Cognitive overload when performing 3D interactions
Lack of standardization

2. Intuitive 3D Interaction Metaphors
Virtual Pointer Metaphors
are natural and intuitive
require low effort
usable for local and remote selection
Concept of Improved Virtual Pointer Metaphor (IVPM)
afford unique selection without requirement of an exact hit
usage of adequate visual feedback about active object
different presentation

3. An Example VR System Architecture

4. (Semi-) Next Generation UI?
Autostereoscopic Displays
Standardized UI by using the desktop metaphor
Intuitive to use through WIMP paradigm
No instrumentation of the user
