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
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
An Example VR System Architecture
(Semi-) Next Generation UI? Autostereoscopic Displays Standardized UI by using the desktop metaphor Intuitive to use through WIMP paradigm No instrumentation of the user
