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

(Semi-) Next Generation UI?

• Autostereoscopic Displays
• Standardized UI by using the desktop metaphor
• Intuitive to use through WIMP paradigm
• No instrumentation of the user
