Angeling 2D pictures to mimic human sight -> stereoscopic 3D image
Needs to track head position and orientation with a tracker
What is sythetic and what is captured content in VR?
Synthetic content = syntheticaly created out of bacic 3D shapes + simulated physics
Captured content = imaging techniques
What is simulation sickness?
Uncomfortable symptoms when using a VR system. Intensity can differ from person to person
How can simulaton sickness be prevented?
Reducing the delay between motion and rendering of corresponding sensory information
Improve screen refreshing rate
Keep sensory information as synchronized as possible
What are major cues of lateral localization (at the side)?
Interaural time difference (ITD)
Interaural level difference (ILD)
